Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?

Stop valve: a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very cooperative for cutting or regulating and throttling.Advantages: in the process of opening and closing, because the friction between the valve and the sealing surface of the valve body is smaller than that of the gate valve, the utility model has the advantages of wear resistance. Second, the opening height is generally only 1/4 of the seat channel; therefore, it is much smaller than the gate valve; usually there is only one sealing surface on the valve body and the disc; therefore, the manufacturing process is better and the service is easy to maintain. Because its packing is generally a mixture of asbestos and graphite, it has a higher temperature resistance. Steam valves are normally used with stop valves.Disadvantages: as a result of the medium through the valve flow direction has changed, so the minimum flow resistance valve is higher than most other types of valves; second, due to longer travel, opening slower than the ball.

Q:Analysis of the advantages of elastic seat sealing gate valve?

General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.

Q:What are the standards for the execution of cast iron dark pole gate valves?

Three, cast iron gate valve structure features:1.. The structure is simple and compact, the design is reasonable and novel, the rigidity of the valve is very good, the passage has a large flow area, the medium is unimpeded, and the resistance is small;2., the sealing surface of the material selected carbide and stainless steel, has a reliable sealing performance, long service life;3. cast iron dark rod gate valve using graphite material for packing, easy to operate;4., can use a variety of driving methods, such as manual, electric, pneumatic, gear drive, etc.;5., the position of the two sides of the gate valve is symmetrical, so the medium can flow freely on both sides, and the installation is very convenient;6. cast iron hidden rod gate valve structure length is short, the quoted manufacturing process is good, the scope of application is very wide;

Q:What valve is z45w gate valve?

Cast iron gate valve with turbine head, please contact me

Q:Soft sealed gate valve and hard sealing gate valve which good?

If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.

Q:What is the difference between an elastic gate valve and a rigid gate?

Brief introduction: the valve gate valve is a gate 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. 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.

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:Fire protection gate valve from the wall how many distance there is no regulation?

Don't know don't answer. "According to the provisions of article 6.2.13 GB50038-2005" code for design of basement for civil air defense engineering, into or through the door unit between the door closed wall should be set up in the inner side or two nominal pressure pipeline is not less than 1.0MPa, the spool is stainless steel or copper gate or globe valve water pipe from the air enclosure structure. The installation position from the wall should be not more than 200mm.

Q:What does "Z45W-10T" mean?What does each letter stand for?

W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;
