When the pressure in the container drops below the allowable value, the valve has automatically shut down, so that the vessel pressure is always lower than the upper limit of allowable pressure, automatic protection from accidents that may occur due to overpressure, it is also known as pressure vessel safety valve final protection devices. Safety valve can automatically open and close according to pressure of work, usually installed in equipment pipeline protection system security or closed system. Safety valves are automatic valves, mainly used in boilers, pressure vessels and piping, control pressure does not exceed a predetermined value, for personal safety and equipment operation plays an important protective role. Safety valve is a safety valve, its opening and closing pieces by the external force is normally closed state, when the media pressure equipment or pipeline increases, automatic opening exceeds a predetermined value, through to the outside of the system to prevent the emission medium medium pressure pipeline or equipment exceeds a predetermined value. When the equipment or pipeline pressure exceeds a predetermined value, which automatically open relief, to ensure that equipment and the pipeline medium pressure within the specified value, to prevent accidents. The valve automatically opens, the media from releasing, reduced; when the pressure returned to normal, the spring pressure turn the valve to the seat, the valve automatically closes. A safety valve to prevent the line or class of device is the medium pressure exceeds a predetermined value, so as to achieve security purposes. Kind of a safety valve in the form of import safety valve lever hammer hammer 1. leveraged safety valve is the use of leverage to balance the weight and role of the force on the valve. According to the principle of leverage it can use smaller mass weight by increasing the leverage effect of a larger force, and by moving the position of the weight (or mass conversion hammer) to adjust the safety valve opening pressure. Simple lever hammer safety valve structure, adjust easily and more accurately, the applied load will not increase the valve flap and a larger increase for higher temperature of the occasion, it was more commonly used in the past, especially It is used in high temperature boiler and pressure vessel. But hammer lever safety valve structure is relatively bulky, easy loading mechanism vibration, and often due to vibration leakage; lower its back seat pressure, not easy to close after opening and holding tight. 2. Spring inching valve spring Weiqi safety valve compression spring force to balance the role of the force on the valve. Spiral ring-shaped spring compression can be adjusted by turning the nut on top of it to regulate the use of such a structure can be corrected according to the safety valve open (setting) pressure. Spring inching valve structure is compact, lightweight, high sensitivity, the installation location is not limited, but also because of the sensitivity of the vibration is small, it can be used on mobile pressure vessel. The disadvantage of this safety valve is the added load will occur with the opening of the valve changes, that with the increase of the valve flap, increasing the amount of compression of the spring acting on the valve's power will also increase. This rapid opening of the safety valve is unfavorable. In addition, the valve spring on the long-term due to high temperatures leaving the affected stretch is reduced. When used in a high temperature container, often considered spring insulated or thermal issues, allowing the structure becomes complicated. 3. The pulse valve pulse valve from the main valve and secondary valve structure, driven by pulsed operation of the main valve and auxiliary valve, its complex structure, generally apply only to safety discharge large boilers and pressure vessels. The spring safety valve spring safety valve discharge mode according to different media, and can be divided into fully enclosed, semi-enclosed and open, three. 1. closed fully enclosed valve exhaust valve, the gas all through the tailpipe emissions, the media can not leak between the outside, mainly for medium toxic. Container of flammable gas. 2. The semi-enclosed portion of the gas valve semi-closed valve discharged through the exhaust pipe, but also part of leakage from a gap between the bonnet and the valve stem, the multi-media to not pollute the environment for container gas. 3. Open valve open valve bonnet is open, the spring chamber and the atmosphere, which will help reduce the temperature of the spring, mainly for the medium is steam, and does not pollute the atmosphere of hot gas container. Import safety valve installation and maintenance of a safety valve should be installed vertically highest position in the pot business, set boxes. Between the valve and the drum or header shall not be equipped with access to the steam outlet pipe and valves. 2, the lever hammer safety valve should prevent their own mobile devices and limit leverage deviant lead frame, spring safety valve should lift the handle and prevent casual twist the adjusting screw means. 3, for the rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; for the rated pressure is greater than 3.82MPa steam boiler safety valve throat diameter of not less than 20mm. 4, the valve connecting the boiler tube, its cross-sectional area should not be less than the cross-sectional area of ??the valve imports. If several valves installed together on a short pipe and drum directly connected via a short tube cross-sectional area should not step on all exhaust valve area of ??1.25 times. 5, the safety valve should normally be installed in exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area, to ensure that the exhaust flow. Safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and not allow the installation of drainage pipe valve. 6, rated evaporation to 0.5t / h boiler, at least two safety valves installed; Rated evaporation is less than or equal to 0.5t / h boiler, at least install a safety valve. Separable economizer outlet at the outlet of the steam superheater safety valve must be installed. 7, the safety valve of the pressure vessel is preferably mounted directly on the pressure at the highest position on the container body. Liquefied gas tank valve must be installed in the gaseous phase. Generally available short tube connected to the container, this safety valve spool valve diameter shall be not less than the diameter of the valve. 8, the safety valve shall be installed between the container and general valves or containers of flammable viscous medium, in order to clean or replace the safety valve of convenience, can be equipped with shut-off valve, the shut-off valve must be all in normal operation open and add seals to prevent tamper. 9 of explosive or toxic media pressure vessel, safety valve discharge media must have safety devices and recovery system. Installation leveraged safety valve must remain vertical position, the spring safety valve is also preferably mounted vertically, so as not to affect their operation. It should also pay attention to the mounting fits, concentricity and should be part of each bolt even force. 10, newly installed safety valve should be accompanied by product certification, before installation to be recalibrated, to seal and issue a check valve. 11, outlet valve should be no resistance, avoid backpressure phenomenon, if the installation of the drain pipe, which should be greater than the inside diameter of the outlet valve diameter, valve excluded mouth should pay attention to antifreeze, for containing flammable or toxic, poisonous media container, outdoor drain pipe should be through a safe place or proper disposal facilities, drain pipe fitted with any valve are not allowed. 12 can not be equipped with any valve between the pressure equipment and valves, to Sheng flammable, explosive, poisonous or viscous medium container for easy replacement, cleaning, loading valve, its structure and diameter dimensions should interfere with the normal operation of the safety valve. In normal operation, the cut-off valve must be fully open and add seals.
