cock typeCheck ValveManufacturer, gate valve overview The opening and closing part of the gate valve is the gate plate. The movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, which is not suitable for adjustment and throttling. WedgeType gate valveThe ram can be made into a whole, called a rigid ram; it can also be made into a ram that can produce trace deformation to improve its manufacturability and make up for the deviation of the sealing surface angle during processing. This ram is called an elastic ram. Compact structure, beautiful appearance, full passage channel, small flow resistance coefficient. Sealing vice-material matching reasonable, long service life. The structure of the gate is: elastic wedge-shaped single gate or rigid wedge-shaped single gate.StemThe surface is nitrided and has good corrosion resistance and friction resistance. The filler is made of fluorine material, which has reliable sealing, flexible operation and small opening and closing torque. Various pipes can be selectedFlange standardAnd flange sealing surface type, also can choose manual, worm gear drive, electric, pneumatic, hydraulic and other driving mode, to meet the different needs of users.

Cock check valve manufacturers, expansion joints are socket pipes, the outlet nozzle of each socket joint is plug-in type, and each socket joint can be connected by bolts. The expansion joint is a socket pipe, and the outlet nozzle of each socket joint is a plug-in type. Allowed elbows, sequential elbows, negative pressure elbows, valves, various conduits, clamps, etc. In the pump system, due to the layout of the site and the requirements of the equipment, often used in the local setting of the pump. 1. use method The power distribution of the water pump is generally installed at the top of the water pump room, and the cooling water is installed in time, so that the water pump and the pipeline will not directly emit pressure to the water pump room.

All kinds of industrial automation production of pipeline flow, pressure, temperature control. For example: electric power, metallurgy, petrochemical, environmental protection, energy management, fire protection system, etc. The sealing surface is less brushed and eroded by the medium. No turbulence, no pressure reduction. The structure length is short, the manufacturing process is good, and the application range is wide. Erosion and abrasion are easily caused between the sealing surfaces, and maintenance is difficult. The size is large, the opening needs a certain space, and the opening and closing time is long. Single gate pole type, double gate plate type and elastic gate type; parallel gate type gate valve can be divided into single gate type and double gate plate type.

Professional focus on the original original goods, quality for the enterprise, moral load, always maintain the brand. Shanghai Fanyu fluid equipment product quality is stable and reliable and with its unique performance in the majority of users enjoy a high reputation, continue to introduce digestion of foreign advanced, self-developed all kinds of special conditions regulating valve, applied to the automation of complete sets of technology progress. The pressure reducing valve is also a kind of pneumatic ball valve, then the pressure reducing valve is how to achieve the purpose of work, what is its working principle, let's look at the relevant instructions. Pneumatic ball valve is compressed air as the power, so the pneumatic ball valve in the use of the process often appear air leakage. take a look at below pneumatic ball valve air leakage way what are the bar. Answer: The structure and function of pneumatic stainless steel ball valve 1. floating pneumatic V-shaped ball valve The ball of stainless steel pneumatic ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end. ask how to control the flow of pneumatic ball valve? answer pneumatic ball valve is evolved from the plug valve. It has the same rotation 90 degrees action, except that the cock body is a sphere, with a circular through hole or channel through its axis.

Cock check valve manufacturers, whenever the valve stem seal is damaged due to fire, metal contact will be formed between the convex step and the valve body to ensure the valve stem seal and antistatic function: a spring is arranged between the ball, the valve stem and the valve body to export static electricity generated in the switching process. the actuator adopts a new series of GT pneumatic actuator, with double-acting and single-acting (spring reset), rack and pinion transmission, which is safe and stable, large diameter valve adopts AW series pneumatic actuator fork drive, reasonable structure, large output torque, double acting and single acting, gear type double piston. It can provide users with corresponding national standards, ANSI, JPI, JIS, DIN and other foreign flange standard products. The flange distance can be determined according to the needs of users. The internal thread connection gate valve and butt welding connection gate valve are divided into 100 degree type, two-stage type and stage type. The valve body castings adopt imported advanced technology, with reasonable structure and beautiful appearance.

In the cast iron gate valve market, there are only two types, balance type and arrangement combination type, of course, there are software balance type and mechanical balance type. Balance type: a type used in cast iron gate valve. The arrangement combination type is the center, the stretching balance type is the cross-sectional shape, and the arrangement combination type is the upper corner shape. This kind of gate valve has simple structure, arrangement and convenient operation, and is usually not suitable for segmented propulsion. Mechanical balance type: arrangement combination type is divided into two types: type 9 and type 11. Type 3 includes two types of movable and movable pressure force, and the movable type can be divided into suction spring type and pressure spring type. Both belong to the spring-loaded gate valve, and the balanced pressure type includes the reciprocating type and the metal pipe type. In order to ensure the balanced operation of water, gas, steam and water, the design requirements of water pipes are level, level and level respectively. Waterway boxes at all levels can accommodate 6 pipes and waterway appliances, with a total water flow of 8-10m3/s.

The valve is an accessory of the pipeline transmission medium. It is used to change the flow direction of the pipeline section and the medium, and control the pressure, flow, and temperature of the transmission medium. It has the following 8 functions. Gate valves, globe valves, butterfly valves, ball valves, plug valves and other valves can be used to connect or cut off the various stages of the pipeline medium. Regulating valve, throttle valve, pressure reducing valve and other valves can be used to adjust the medium flow and pressure in the pipeline. Distribution valve, through the plug valve, (through/through) ball valve can be used to change the medium flow direction of the pipeline.
