The use of the lower pressure valve way and pay attention to the things of project with oxygen gas reduced pressure valve is basically the same. But still the general principle: reduce the pressure valve is after opening and closing the throttle, reduced the inlet pressure to a certain demand of outlet pressure, and make the outlet pressure to maintain safe. 2, turn the adjusting screw, change the height of the valve to open, so to adjust out high body over limit and achieve the required pressure value. Their life and suitable for use in different medium. However, should also be pointed out that: dedicated to reduce pressure Industrial Valves normal in other gases. Out so imported high-pressure body by high pressure chamber after throttling pressure lowered into the low pressure chamber, and the export to the office. In order to avoid misuse, a bit of a special reduced pressure valve with right between the cylinder and use special signatures. Reduced pressure valve and cylinder think appropriate and use the surface of the hemisphere petition, by tightening the screw nut to make both the absolute. Hi-pressure dying body blow the dust before installation. The low pressure table outlet pressure can be adjusted by the screw stem. ( 4) When resting office, should put a net the lower residual air in the pressure valve, and then loosen adjusting screw so that permanent compression elastic element variant. High pressure table of value for the pressure of the gas storage in the cylinder. But there is still a little gas, corrosive gases such as ammonia, the demand for lower pressure valve. These two types of qualifications for the best proportion of stem flow valve itself special properties and flow range. Normal for geometric type or with geometric special properties. 3, to reduce the pressure valve is equipped with safety relief valve. Such as hydrogen and propane are right and use the left tooth turnbuckle, also known as reverse turnbuckle, when installation should be believing. ( 5) Reduce the pressure valve should prevent the impact of oscillation, can not contact with corrosive thing. 。 Have in common market nitrogen, air, hydrogen, ammonia, acetylene, propane, moisture and other special reduce pressure valve. These valves should be useful for stem range selection, namely the maximum flow of 20 to 80 one hundred percent and one hundred percent. Q: the use of oxygen gas reduced pressure valve to answer: after the office of oxygen gas reduced pressure valve by valve pressure of stem. ( 2) Installing a lower pressure valve should confirm whether the petition specifications with the joint of the operation system of the cylinder and exactly the same. 1, using the first open the cylinder when the master switch, and then clockwise (low pressure gauge pressure adjustment screw, the compress the main spring and transmission film, spring block and the plunger and valve open. But ordinary reduce import pressure differential pressure valve requires a 0 or higher. 2Mpa。 If because the valve gasket, valve damage, or because other comprised, pressure to rise and exports more than a certain value, the safety valve will be semi-automatic open the exhaust. Also available when the indispensable materials such as ptfe gasket. Because of this, when in use, should maintain the two hemispheres of the surface is bright and clean, so as to ensure satisfactory airtight effect. Supreme inlet pressure mostly, the minimum inlet pressure not less than 2 of outlet pressure. 5 times. The valve must be in a certain extent, reduce pressure ratio value is higher than the system; Even when the maximum or minimum flow it should also be able to is the utility or the utility stem signal of a response. This kind of valve in the pipeline should be water there is no danger. ( 3) Oxygen gas reduced pressure valve should be banned from contact with grease, lest send to ignite fuel police accident. It is to try to take care of reduced pressure valve and make the safe use of devices, and reduce the pressure valve revealed the fault signal device. Different ways have different specific office principle. When the pressure sensor testing to directed valve pressure, the lower pressure valve valve opening decreased; After testing to reduce the pressure valve pressure decreases, and reduce the pressure valve valve opening, to satisfied stem requirements. Outlet pressure and specifications, common for, the outlet pressure of the Buddha. Other Marine valve to reduce the gas pressure valve attention problems: a little gas, such as nitrogen, air, argon gas for a long time, can see fit and use oxygen gas reduced pressure valve. Lower pressure valve category is numerous, common are: the guide piston reduce pressure valve, diaphragm pressure valve, striped tube reducing pressure valve, proportional reducing pressure valve, self-reliance reduce pressure valve, direct utility piston pressure valve, back pressure regulator, etc. Oxygen gas reduced pressure valve of high pressure chamber and the cylinder petition, low pressure chamber for gas exports, and to use the system. Oxygen gas reduced pressure valve installation using the attention of the project: ( 1) According to the requirements of use, oxygen gas reduced pressure valve has many specifications.
