Imported lined valve

Imported lined valve Overview: gate valve opening and closing parts is, the direction of movement of the fluid direction perpendicular to the gate, gate can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high for 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate board called the flexible gate. Valve types, according to the sealing surface configuration can be divided into wedge gate-type valve and parallel gate-type valve, wedge gate-type valve can be divided into: a single gate type, double plate and flexible gate type; parallel gate-type valve can be divided single-gate type and double plate. Divided by the threaded stem position can be divided into two clear shot valve gate and dark bar. When the valve is closed, the sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. When the valve is closed, the sealing surface can only rely on media pressure to seal, that is, only the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Gate valve with the valve stem linear movement, called the lift rod valve (also called clear shot valve). Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to the diameter of the 1: 1 times, the fluid channel is completely smooth, but at run time, this position is not monitored. Actual use, is the apex of the stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the position of the valve fully open. Therefore, the fully open position of the valve, according to gate position (ie, stroke) to determine. Some valve stem nut located at the gate, handwheel drive stem rotation, leaving the gate to upgrade, this valve is called the rotating rod valve or valve called the dark bar. Imported lined valve characteristics: First, lift the gate sealing surface, can scrape the sealing surface of the adhesive material, automatic clean up debris. Second, the stainless steel gate seals to prevent leakage caused by corrosion. Third, the hard surface to ensure all gold seal seal wear and requirements. Fourth, the valve sealing surface is no recess, no matter accumulates, to ensure open and flexible. Five short length of the structure, saving material, installation space effectively support the pipeline strength. Six stuffing seal design science, so that the seal is safe, effective and durable. Seven triangular bracket save raw materials, to ensure the required mechanical properties. Eight, guide block valve on the shutter right movement, four ram extrusion block ensure an effective seal. Nine, body stiffener designed to improve the strength of the body. Ten, durable stainless steel stem, stud to open and close more quickly. XI, the drive mechanism can be arbitrarily chosen. Twelve, more than 150 caliber, fully enclosed structure, more effective open and prevent leakage. Thirteen, Viton sealing surface to achieve sealing effect, increase the use of temperature. Fourth, vulcanized rubber sealing surface directly in the valve body, will not fall off. Imported lined valve installation and maintenance should note the following: 1, hand wheels, handle and drive mechanism for lifting are not allowed to use, and forbid the collision. 2, Gate Valve should be mounted vertically (ie, stem in a vertical position, the hand wheel at the top). 3. With a bypass valve to open the bypass valve opening should be preceded (in order to balance imports and exports and reduce the pressure opening force). 4, with the valve drive mechanism, install the required product specification. 5, if the valve switch is used frequently, lubrication at least once a month. 6, the valve is used as a cut-off media, in the full flow through, then the pressure medium to run minimal loss. 7, the valve is usually applied to less frequent opening and closing, and keeping the shutter fully open or fully closed condition. 8, the gate does not apply to a regulator or throttling. For the high-speed flow of medium, open the gate in local conditions can cause vibration of the gate, while the vibration it might damage the gate and seat sealing surface, while the throttle damper will suffer erosion of the medium.
