- Q:How about the valve?
- In 1998 began the formal production of valves. As the company expanded in size, in September 2003, changed its name to the British HV VALVES LIMITED (HUDDERSFIELD), referred to as the United kingdom. The design and production of various types of valves, widely used in power, oil, chemical, offshore platforms and other fields, with its excellent quality and service to win the praise of the vast numbers of users.
- Q:What's the meaning of the "single valve"?
- There are nuts, plants, flush three parts. The pipeline steel or steel ingot forging molding machine fittings, connection form the socket welding and threaded, socket welding steel pipe is inserted into the socket is in welding, so called "socket joint, thread connection pipe is screwed in the screw through connection.
- Q:Where is the Shanghai valve? What brand is good?
- A lot of Shanghai brand brand of Shanghai KaiWeiXi, Department of finance the Kemei high Lidun Shanghai Karon these are good
- Q:Where is the valve used?
- Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water works,
- Q:What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism
- Tyco doesn't know much about it. It's often written in the bidding documents, but there are very few actual purchases, so I don't evaluate it any more. The strongest of the balance valves is the TA (Swedish). He was the originator of the balancing valve. Super high-rise complex, the hotel part, you mention these kinds of valves are applied a lot.
- 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's the name of the valve?
- Specific models only go to the original manufacturers to find, and want to use other valve replacement is not impossible, want to provide detailed parameters. Let's go to the valve manufacturer!
- Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
- The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
- Q:Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?
- Do not need ah, at most installed a gate valve, globe valve, and so on, installed on the exhaust valve on the line.
- Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise
- 1/2, 1/4 valve is our usual popular name. "1/2" and "1/4" refer to the size of the valve bore, in inches. And there are 3/4, 3/8 to 24, 30, and 36 inches. Relative to our country on the valve bore that is "DN."". There are about 1 inches =25.4MM conversion, so in general we are 1 inches of the valve is DN25 valve.
