Q:Who knows a door valve heating valve how to open?
The valve has a device resembling a cylinder lock without a dedicated key. However, your home heating is not hot, the valve does not have much relationship. As long as the hole on the valve is parallel to the pipe, the valve is fully open.
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
Q:What is a lift rod valve?
The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised
Q:What valve is the VENT?
VENT generally use a check valve (resembling a screw, spring preload), also directly using the plugA two-way sealing type ball valve for example, in order to detect the leakage of the pressure after the end, also for pressing the cavity is convenient, usually in the body cavity external to the up position to open a checking leak, which is VENT.
Q:Valve connections - two how do different connections work?
The inlet and outlet of valve are respectively connected in two different ways: one end adopts flange connection, the other end adopts thread or socket.
Q:How many kinds of valves are there in the water pipes?
butterfly valveThe butterfly valve has the advantages of simple structure, small volume, light weight, only by a few parts. But only can rotate 90 degrees rapid hoist, simple operation, while the fluid control valves have good properties. The butterfly valve in the fully open position, the disc thickness is only when the medium flows through the power, by the valve the pressure will be very small, so it has better flow characteristics. Our company is mainly metal plastic butterfly valve, eccentric butterfly valve, butterfly valve, inlet butterfly valve, wafer butterfly valve and so on.Globe valveBall valve and plug valve is the same type of valve, only its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing the valve. A valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow, the ball valve is a new valve in recent years has been widely using.
Q:How do you calculate the pressure difference between the front and rear of the valve?
The valve according to feature points, can be divided into isolation, cut off, check, overflow and regulation, which belongs to the regulation is more complex, such as for a compressible medium, constant flow regulating valve after the pressure is more and more big, natural gas pipelines are now part of the regulating valve the self,
Q:What are the other valves used for the control of dual-use items?
This is the export licence for dual-use items and technologies.The electronic key issued by Beijing is only qualified for this certificate.We can do that
Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
Q:What does valve 41F-40C mean?
Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
