- Q:How to check the quality of the valve?
- First, visual inspection of the valve appearance, followed by a spectrometer to check the material, material, and then look at the hydraulic test pressure, whether there is leakage.
- Q:What are the types of valves?
- 1.2.3 classification by body materialx09 (1) non-metallic material valves: such as ceramic valves, glass fiber reinforced plastic valves, plastic valvesx09 (2) metal valves: such as copper alloy valves, Aluminum Alloy valves, lead alloy valves, titanium valves, Monel alloy valves, cast iron valves, carbon steel valves, cast steel valves, low-alloy steel valves, high alloy steel valves.x09 (3) metal body lining valve: such as lining lead valve, lining plastic valve and lining enamel valveHa ha, I answered it only a while ago
- Q:How to carry out the valve strength test and air tightness test?
- Refer to the GB/T13927 or ISO5208 standards and need to pass it to you
- Q:1) the valve plate, valve gate valve, the difference (my personal understanding is that if it is on the ball, called the valve, if the valve is called the gate, is actually a meaning in different valve called, please help me understand it right?)2) valve clack. What's the spool?3) the valve seat is welded inside the valve, or is it directly installed inside without welding?4) when opening the valve, if the valve seat is not welded, then, under the pressure of the medium, why not open the seat?.5) excuse me, pressure self sealing (my personal understanding is that when the valve is closed, the valve plate and valve seat depend on the pressure of the media, and they fit together to seal the effect
- 1. can be understood that way2, check valves, stop valves, and throttle valves are called valves3., welding, thread, and there is a cylindrical indentation, as well as plastic deformation press in4, without opening, there is a sphere or other block, open the moment, the pressure will come down, the media through the channel, attack or blocked by the ball, huh, huh5, the pressure self tight refers to the middle flange, where the greater the pressure, the more reliable sealing, within a certain rangeWhen the cut-off valve diameter is less than 150, the medium is low, the inlet is higher and the outlet diameter is greater than 200Some of them are self locking by thread, and some of the globe valves are equipped with locking devices
- Q:What are the key valve enterprises in China? Mainly in those areas?
- Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
- Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
- You really want to go to the big water to fix the valve and be prepared for the follow-up, just in case
- Q:What is the KVS in the valve parameter?
- KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
- Q:I'm going to put a solar energy and an electric water heater installed in the same hot water pipe, a valve, a valve open and close the valve B and vice versa the installation of solar and electric water heater, there can be no linkage valve?
- In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
- Q:Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!
- A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!
- Q:What does the 4 point valve mean?
- That is not clear, American Standard or GB, or what other
