Valve is a opening and closing the gate assembly, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, discomfort door parameter varies, usually 5 degrees, the medium temperature is not high for 2 ~ 52 '. Improve the process, make up the sealing surface angle in the process of the deviation, which is called the gate.
Motion editing valve closed, the sealing surface can only rely on media pressure to seal, which only rely on media Z41h flange wedge gate valve pressure on the sealing surface of the disc to the other side of the valve seat to ensure the sealing surface, which is self sealing.
Most of the valve is forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface of the seal.
Movement: gate valve with the valve stem together for a straight line movement, also known as the gate valve.
Usually on the lifting rod with trapezoidal thread, through the valve on the top of the nut and the body of the guide slot, the rotating motion into a linear motion, that is, the operating torque into the operating thrust.
When the valve is opened, when the gate height is equal to 1:1 times the diameter of the valve, the fluid passage is completely free, but at the time of operation, the position can not be monitored.
Actual use, is the apex of the stem as a sign, that is, the open position, as its fully open position. In order to consider temperature changes occur locked phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as a fully open valve position.
Therefore, the valve fully open position, according to the location of the gate (that is, the stroke.
Some gate valve stem nut is located on the gate, the hand wheel rotation to drive the valve stem rotation, and so that the gate to upgrade, this valve is called the rotating rod gate valve or called the dark bar gate valve.

- Q:What are the features and uses of the gate valve?
- What is gate valve? What is the purpose of forged steel gate valves? What are the features of forged steel gate valves?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. The gate valve movement direction perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angles vary with valve parameters. Gate valve drive classification: manual gate valve, pneumatic gate valve, electric gate valve.DefinitionGate valve means the closing of the valve (gate) along the central line of the vertical direction of the valve. The gate valve is mainly used for cutting in the pipeline.The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is betterValve also has shortcomings:The overall size and opening height are larger. Larger space required for installation.In the process of opening and closing, there is relative friction between the sealing surfaces, which may cause galling.Gate valve generally has two sealing surface, processing, grinding and maintenance to increase some difficulties.
- Q:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.
- Flanges for piping above DN50,DN50 (below) can be made of wire or flange (flange for pressure piping)
- Q:Function of gate valve
- 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.
- Q:About fire valve is gate valve or butterfly valve problems?
- Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
- Q:What is an inverted seal gate valve?
- When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.
- Q:GB 300 gate valve, a multi?
- GB DN300 flanged gate valve, PN10 manual 245kg bevel gear 315Other pressure levels, please specify specific pressure.Wenzhou Chaoda group Agel Ecommerce Ltd to provide the answer:
- Q:The valve safety valve check valve + + + = exposed part of a water pump adapter? Five
- As everyone knows, the water pump adapter includes: gate valve, check valve, safety valve, the water outlet pipe and a combination of exposure. If it is a wall type, it should also include a decorative board. If the model is relatively simple and portable pump, pump adapter classification: SQS old ground fire pump adapter, SQD new type of pump adapter, SQB wall type water pump adapter. You can use Baidu Search: Shanghai Huanyao pump adapter
- Q:What is the difference between a flanged gate valve and a wire gate valve?
- Flanged gate valves are flanged and must be welded to the flanges of the pipe, bolted together
- Q:Gate valve is gate valve, gate valve specifications, model code is generally what?
- Gate valve is not gate valve, gate valve does not have a fixed specific model
- Q:Is the axial force and torque of the wedge gate valve the same?
- B higher temperature. C nice wedge single gate valve is suitable for high temperature medium easy to coking. Flexible gate valve features: high temperature, a wedge type single gate valve in a special form. Comparison with wedge gate valve.
