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 does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
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:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
It's not the valve! But the price relationship!
Q:The difference and use of gate valve and stop valve
Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
Q:Gate valve z41t what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy
Q:What does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
Q:Function of signal butterfly valve and gate valve
The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. It can be used as regulating and throttling devices in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. It is widely used in high buildings, fire protection systems and other piping systems that need to display valve switching status.
Q:Notes on flat gate valves
Use, maintenance, maintenance and precautions1. valve before leaving the factory have made strength and sealing test, the use of all connections should maintain the initial state.2. this series of valve operating handwheel is marked with open and close rotary direction, and the upper part of rod is equipped with open and close height gauge for regulating indication.3. when the valve and pipeline welding, the valve should be opened, appropriate to protect the neck with moisture, minimize heat conduction, to prevent damage to the sealing packing parts.4. when the valve is closed, the lever shall not be used. When the gate is closed to the top, the handwheel shall be turned 1/2 so that the gate is in a floating state.5. in the use of the valve should be regularly to the valve cap injection grease joint into the quantitative grease.6., the valve in use, such as vulnerable parts and leakage, should be replaced in time.7., the valve in the overhaul process, the cavity should be cleaned, the assembly should be added to the transmission parts of grease.8. valve storage during the shutdown, the gate should be in the closed position, long-term storage should be placed in ventilated dry place, regular inspection and maintenance.
Q:What kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
Q:What are the types and product categories of knife gate valves?
Knife gate valve drive mode:Manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electronically controlled, hydraulic and pneumatic drive. Knife gate shape: bright rod, dark rod two kinds. Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine and so on.
