Product information
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.
The structure of editor mainly composed of a valve body, a valve rod and a butterfly plate and a sealing ring. The valve body is cylindrical, with short axial length.
The working principle of butterfly valve butterfly plate driven by the stem editor, if turned 90 degrees, will be able to complete a hoist. Change the deflection angle of the butterfly plate, you can control the flow of media.
Working condition and medium: butterfly valve used in furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, metallurgical and chemical industry and environment-friendly power generation, building to drainage engineering system transport all kinds of corrosive and non corrosive fluid pipe for regulating and truncated medium flow.
Butterfly valve uses edit (English: butterfly valve butterfly valve refers to close (valve or butterfly valve plate) for the disc, around the valve axis of rotation to achieve the opening and closing a valve, in the pipeline mainly cut off and throttling action. Butterfly valve opening and closing parts is a disc - shaped disc, in the body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Valve fully open to fully closed is usually less than 90 DEG, butterfly and Butterfly Bar itself is not self-locking capability, in order to position the disc to install the valve stem on the worm gear reducer. Using worm gear reducer, not only can make the butterfly board with self locking ability, so that the butterfly board to stop at any position, but also to improve the operating performance of the valve. Special butterfly valve for industrial characteristics can resist high temperature and high applied pressure range, the valve nominal through large diameter, and the use of carbon steel valve manufacturers, valve plate sealing ring using the metal ring instead of rubber ring. Large high temperature butterfly valve using steel welding manufacturing, mainly used for high temperature flue gas channel and gas pipe.

- Q: What are the working principles of the electric gate valve?
- Ordinary type electric valve should be equipped with the control box, the motor is the true story and the inversion, and in general to a trip signal signal is normally open and normally closed, closed in place are normally open and normally closed two points according to their own needs wiring, three lines and then open and close control of the line of control there are also 4 lines to control some manufacturers, as well as the valve position, some three lines connected with the potentiometer, some installed valve position transmitter is connected with two lines, and over torque protection fault signal.
- Q: What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve
- Stop valve and gate valveThe working 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 outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
- 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: Why is gate valve or butterfly valve used for water pump?
- General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
- Q: What is gate valve (with force transfer joint)?
- Flange valve is equipped with a force expansion joints, easy installation
- Q: What is the allowable leakage rate of the gate valve D?
- In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.
- Q: Yes, soft sealing gate valve can reach 25 kilograms, Fujian light valve company has this type of soft sealing gate valveAnonymous browsing | 28 times
- Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
- Q: What does the gate valve SZ45X-1.0 stand for?
- Z- stands for gate valves, 4 for flange connections, 5 for wedge wedge single gate, X for rubber seals, and 1.0- for PN1.0MP
- Q: What is plug welding gate valve?
- Socket welding valve valve cover design in three forms. The first is forging steel bolt type valve cover, according to this design form design of the valve, the valve body and the valve cover bolt nut connection, spiral wound gasket 316 clamp flexible graphite manufacturing: seal. Customers have special requirements can be used when the metal ring connection. Second design form is the welded bonnet, according to this design form of the valve, the valve body and the valve cover with a threaded connection, welded seal. Customers have special requirements can be used when the third is connected through welding. Self sealing valve cover, according to this design form design of the valve, the valve body and valve cover with a threaded connection, pressure from the dense ring seal.The editing characteristics of 1 valve design and manufacture in accordance with API602 and ASME B16.34. tested according to API 598, marked by MSS-SP-25.2. full diameter or diameter shrinkage 3 rod bracket type 4 self centering sleeve type 5 pressure plate bolt connection, spiral wound gasket seal type valve cover nut connection, welded seal type valve cover and screw connect the internal pressure self tightening type valve cover 6 integral sealing seat 7 socket end with ASME B16.118. threaded end (NPT) with ANSI/ASME B1.20.19. valve can be transformed into the throttle type, needle type, ball type and type check
- Q: What is wire feed gate valve? What do you say in French?
- Point to the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connection
