Oxygen valve

Oxygen valve YQY Product description: Model: Nitrogen YQD-25x25, hydrogen YQQ-25x25, oxygen YQY-25x25, air YQK-25x25 high voltage measuring range (0-25,0-25) MPa inlet pressure 15MPa adjustment range 1-15MPa Flow 30m3 / h input thread G5 / 8 "thread M16x1.5 output Dimensions 170x125x165 Weight 1.7Kg Notes: Ф6 outlet with brass fittings quantity discount piston vacuum structure Cover and maternal high quality forged brass inlet pipe filter online cover the inner liner using a special plastic material to make the regulator more stable and smooth YQD-25 action and classification principles of high pressure gas cylinder regulator due to high pressure, and the desired gas welding and gas cutting and point of pressure is relatively small, so you need to use a pressure reducer to the gas cylinders stored in the high pressure gas reduced low-pressure gas, and shall ensure that the required work pressure remained stable throughout the state. In short, the high-pressure gas regulator is reduced low-pressure gas, and maintain pressure and flow regulator output remained stable high-pressure gas regulator by use of centralized and job type categories; according to different configurations can be divided into single-stage and two-stage two; press work principle can be divided into positive-action and reaction type categories. Currently, a common domestic pressure reducer single-stage and two-stage reaction type hybrid (the first stage is a positive acting, the second stage of reaction type) categories based. B, structure and working principle YQD-25 high-pressure reducer body 1.YQD-25 high-pressure reducer is made of brass. two-stage vacuum system 'is substantially similar structure, by the valve top rod, pressure springs, elastic membrane system, vacuum door and other component parts. The first stage decompression system is mainly used in high-pressure gas is automatically reduced-pressure gas, the pressure is reduced to the actual needs of pressure, and then into the second grade vacuum system. In the secondary pressure relief system, when screwing the regulator screw, through the regulator spring, the elastic film loaded and valve mandrel, varying degrees of pressure reducing valve for opening and closing, to be used to adjust the first A reduced level of oxygen into the vacuum system or to stop gas supply. 2. The high-pressure regulator at the inlet connector thread size of 315. 875mm, inner diameter of the joint is 5. 5mm, the inner diameter of the outlet fitting 6mm, The maximum flow rate of 80m3 / h. the regulator body is also equipped with high-pressure oxygen tables and low oxygen table, indicate the high pressure chamber (ie, oxygen bottle) and a low gas pressure in the chamber (ie working pressure). hyperbaric oxygen table The range is 0-25MPa. low pressure oxygen table range is 0- 25MPa. When using YQD-25 high-pressure reducer, when screwing the adjustment screw clockwise, you can open the top pressure valve, high-pressure oxygen begins flowing into the gap the low pressure chamber occurs due to expansion in the low pressure oxygen gas leaving the interior volume of the pressure drop, i.e. decompression. C, the safe use of the pressure reducer 370 (1) when the oxygen cylinder regulator deflated or open operation must be slow. If the valve is opened too fast, the working portion of the regulator due to the adiabatic compression of the gas temperature is greatly improved, so that it is possible to make the parts made of organic materials such as rubber filler, a fibrous pad rubber membrane fire burn and can decompressor completely burned. In addition, since excessive gas discharge static electricity sparks generated and pressure reducer with oil, etc., will cause a fire burning burn regulator parts. (2) Precautions before installation reducer and open the cylinder valve when: Before installing the pressure reducer, slightly open the oxygen cylinder valve, blow off the dirt, to prevent dust and moisture into the pressure reducer. When opening the cylinder valve, cylinder valve outlet operator or other person shall not be aligned, to prevent high-pressure gas suddenly out of wounding. Regulator outlet and gas rubber tube joints must be annealed wire or clamp and tighten; prevent the aspirated dangerous disengagement occurs. Note (3) handling and operation of the pressure reducer: When loading regulator threaded fittings must be taken to prevent slip teeth, so as not to spin shot is not strong. In the course of the work must observe the pressure gauge value. Work should be stopped regulating reducer loosen the screw, and then close the oxygen cylinder valve and the gas pressure reducer inside slowly exhausted, so that you can protect the spring and decompression valve from damage. After work, you should remove the regulator on the cylinder, to be properly preserved. (4) The regulator must regularly repair the school, the gauge must be regularly tested. This is done to ensure the accuracy and reliability of the regulator gauge readings. Regulator found in the use of leakage phenomenon, pressure gauge action not working, etc., should be timely maintenance. (5) pressure reducer freezing process. Regulator found in the course of freezing, thawing with hot water or steam, never use a flame or red iron baking. After the pressure reducer heating, wherein the residual moisture must be blown off. (6) The regulator must be kept clean. Shall not be contaminated with grease, dirt on the pressure reducer, if fat, must be used to wipe clean after. (7) of various gases pressure reducer and pressure gauge shall exchange use, as regulator can not be used for oxygen acetylene, LPG and other systems Note: This production of Linhai City Dahua instrumentation products, commodity copper products, so the price of raw materials and the current copper price as the standard!
