- Q: What is the difference between the copper gate valve and the ordinary material gate valve?!
- The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.
- Q: Function of signal butterfly valve and gate valve
- The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. Available in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powders.
- Q: Z45T-10 what kind of material is the gate valve?
- Cast iron, sealed with copper alloy inside. Shanghai Yu Cheng fluid on the professional production of this thing,
- Q: What is a protective gate valve? What is gate valve knowledge?
- Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,
- Q: Why? God, can you explain to me in detail why?
- The exit of the general pump is the first soft connection (shock absorber), followed by the check valve, and then the partition valve (such as butterfly valve, gate valve, cut-off valve, etc.), this is not the final answer.The question is interesting, and no corresponding information has been found in the relevant standards. We have also discussed the related issues, but differences of opinion is relatively large, the advantages of 1, first installed check valve installed after the valve or butterfly valve, check valve, can be protected, especially in a parallel pump, when the pump does not start, another pump starts when the impact force is gate valve or butterfly valve bear, disadvantages: gate valve or check valve who will protect? There have been a case of butterfly valve is broken. 2, first installed gate valve or butterfly valve installed after the check valve, advantages: can protect the butterfly valve or gate valve, the impact on the check valve to bear. Disadvantages: check valve who will protect, check valve by pressure difference switch, if the high pressure high pressure pipe, pump, if the flow is not stable, so check valve will repeatedly switch, will affect the check valve life. Personal opinion: check valve, check valve performance now have changed, many are using the slow closing check valve, so the impact force is two aspects to bear, because exports are not fully open the valve or butterfly valve, so you can put in check after the gate valve or butterfly valve valve. If not the slow closing check valve installed in the valve or the best after the butterfly.
- Q: What's the difference between open rod gate and dark rod gate valve?
- 4, the dark pole gate valve height smaller size; Ming rod gate valve requires a larger installation space;5, the structure of the rod gate valve is beneficial to the lubrication of the valve stem, and the degree of opening and closing is obvious. The stem thread of the dark rod gate valve is not only unable to lubricate, but also directly accepts the medium erosion and is easy to damage. Therefore, the open bar gate valve is used more widely
- Q: What is the difference between an elastic gate valve and a rigid gate?
- One is cast iron, intermediate rubber gate, one is cast steel, and the other is steel flashboard,
- Q: What is the difference between gate valve Z41T and Z45T?
- The difference between Z41T and Z45T is that 41 is the dark rod, that is, the screw is not out of the turbine, and the 45 is the Ming bar, the screw out of the turbine outside, the price is also different?.
- Q: What is the difference between gate valve and gate valve? Is it the same valve?
- The valve is driven by the valve stem to make vertical lifting of the plate inside the valve body.Gate valve is the same reason. The gate valve and gate valve have steel gate, parallel double gate and so on.So the gate valve and gate valve are the same valve. It's just a different name.
- Q: What is wire feed gate valve? What do you say in French?
- It should be the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connectionI only know their English, I'm sorry I can't help youBox thread valveFlange valve
