Q: Function of signal butterfly valve and gate valve: The signal is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Signal gate valve is usually horizontal installation.

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: Which is more expensive, bronze gate valve or brass gate valve?: But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.

Q: Why does the fire hydrant box in the air defense area need to be added with gate valves?: when the envelope from the introduction of civil air defense, air defense should be set in the side of retaining structure; through the protection unit between the closed wall, should be installed in the pipe walls on both sides of the door closed;2 protection valve nominal pressure shall not be less than 1.OMPa;

Q: Stainless steel gate valve DN150 200300 weight, who knows?: Valve selection of different driving methods, connection forms, structural forms, nominal pressure, sealing surface materials, lining materials, valve body material will affect the weight of the gate valve more or less, it can not be generalized.Take my commonly used Z41H-16P (i.e. PN1.6MPa) series stainless steel gate valve as an example, and the weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.I hope I can help you.

Q: Is the gate valve clockwise or closed?: In general, the valve is clockwise turn off, in the case of special requirements under the opening.

Q: Does the tap belong to a stop valve or a gate valve?: If it is about to pull open and close, it is cock valveIf it is rotated up and down, it is a stop valve

Q: What's the difference between the knife gate valve and the stop valve?: Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!

Q: What's the meaning of flexible z45x-10q door valve?: Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve

Q: What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?: Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
