The products are widely used in water source projects, urban water supply and drainage, sewage treatment, eletric power, petroleum, petrochemical, heat supply, shipbuilding, medicine and metallurgy industries. Equipment are used for regulating or cutting off media in pipelines. Suitable media include water sewage, sea water, air, foodstuff and oil. Suitable for gear operators, electric and pneumatic control actuators.
- Q: Valve flange drawing n- up to what
- A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
- Q: Gate valve Z41H-16Q generally used for what place?
- Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.
- 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 can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
- Because of the unsteady flow of fluid near the inlet and outlet of the valve, the measured data cannot be obtained relatively accurately.
- Q: What are the main types of gate valves?
- According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;
- Q: What is the difference between Z41X gate valve and Z45X gate valve?
- All flange soft sealing gate valve, but 41X is Ming bar, 45X is dark pole
- Q: Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?
- We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection
- Q: What are the differences between the gate valve and the cut-off valve?
- The operating principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outletAt the same time, usually with the cut-off valve instead of gate valve, but the valve can also be used instead of cut-off valve. Valve sealing performance better, but the size is generally not large, the size of the gate valve can be done great.The main difference between them lies in:1, different structure, gate valve structure is more complex than the height, larger size, from the appearance point of view than the cut-off gate valve is short and high, especially the gate height space needs a higher open bar, the selection in the installation space under the condition of limited attention to.2, sealing surface, valve in the opening and closing valve and the valve seat surface always contact and friction between the sealing surface, and thus easy to wear, especially in close off the valve when the valve before and after the great pressure, sealing surface wear is more serious. And the valve once the valve is in open condition, it's seat and disc sealing surface between, not in contact,
- 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: The legend of gate valve and stop valve
- Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions. The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve.The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by.
