Gate valve (gate 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.
Standard or Nonstandard: Standard Structure: Gate Pressure: Medium Pressure Power: Manual Material: Casting Temperature of Media: Medium Temperature Media: Water Port Size: DN40mm-DN300 Place of Origin: China (Mainland) gate valve: Resilient Seated Flanged Cast iron gate valve: DI gate valve Packaging & Delivery
Packaging Details: air plastic bag inside/wooden box outside
Q:What are the working principles of the electric gate valve?
We see you what type of electric valve, is integral or ordinary type, if the overall type Denso took power on the line, is generally 380V and 220V power supply, and then according to their own needs and then open the signal line, in place and closing in place and remote control line, valve position feedback signal the commonly used 4~20ma over torque protection fault signal.
Q:What are the meaning of the cast rigid gate valves z41h-16c?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel
Q:Why does the centrifugal pump start and stop in the case of closing the gate valve?
Centrifugal pump to close the gate valve in the case of the start: the centrifugal pump power increases with its flow rate, when the flow is zero (valve closed), the minimum power to operate. Start the valve off from the angle of the motor. If the valve is started, the motor itself to start the current is larger, coupled with the power of the pump is also large, easy to cause the motor over-current trip, serious will burn the motor.
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: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: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 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 does the fire hydrant box in the air defense area need to be added with gate valves?
Code for design of basement for civil air defence GB50038The installation and installation of the protective valve on the water supply line of the 6.2.13 air defense basement shall comply with the following requirements:OneWhen the water supply pipe from the entrance into, should be set up in the inner protective sealing door;
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.
