The valve core is provided with a reset chamber and a sealing chamber, and a through hole is provided between the reset chamber and the sealing chamber. The through hole is provided with a valve stem that moves up and down. The bottom end of the valve stem is provided with a sealing gasket that matches the communication port and changes the switching state of the communication port. A reset structure is provided between the valve stem and the reset chamber to keep the valve stem in a normal state, and a sealing structure is provided between. This utility model has a simple structure, low cost, convenient processing, and enhances the sealing between the valve core and valve stem. It will not leak at 1.5 times the working pressure, with reliable sealing and more stable performance.

It belongs to the same type of valve and is composed of an electric actuator and a globe valve. The opening and closing member of the electric globe valve is a plug shaped valve disc, and the sealing surface is flat or conical. The valve disc moves in a straight line along the centerline of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem is lifted and lowered without the handwheel lifting), as well as a lifting rotating rod type (the handwheel rotates and lifts together with the valve stem, and the nut is set on the valve body). Electric flange globe valves are only suitable for fully open and fully closed, and are not allowed to be adjusted or throttled.

1. The electric flange globe valve has a compact structure, reasonable design, good valve rigidity, smooth channel, and low flow resistance coefficient.

2. The sealing surface of the electric flange globe valve is made of stainless steel and hard alloy, with a long service life.

3. The electric flange globe valve adopts flexible graphite packing, reliable sealing, and easy and flexible operation.

4. Structural types: elastic wedge single gate, rigid wedge single gate, and double gate types.

5. Widely applicable as an opening and closing device for connecting or cutting off the medium in oil and steam pipelines such as petrochemicals and thermal power plants.

structural characteristics

Carefully selected materials, in compliance with relevant domestic and international standards, with a reasonable structure and beautiful appearance.

2. The sealing surface of the valve disc and seat is made of iron-based alloy or Stellite cobalt based hard alloy, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance, and long service life.

4. The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance and abrasion resistance.

5. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.

6. The valve body material variety is complete, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.

7. The reverse seal is made by connecting the sealing seat with threads or welding austenitic stainless steel on the body, ensuring reliable sealing. The replacement of the packing can be carried out without stopping the machine, which is convenient and fast, and does not affect the operation of the system.

8. Equipped with DZW series multi turn electric device, it has a small housing, light weight, full functions, and can be used with remote computers. It can also be optionally equipped with electric devices according to user requirements.

Application Specification

J941HNormally open electric globe valveMain component materials and main uses

Main external dimensions, connection dimensions, and quality

The working principle of electric flange globe valve and American standard gate valve is to rotate the valve to make the valve unobstructed or blocked. Gate valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium. They are widely used in various industries.

3、 Electric flange globe valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. Electric flange globe valve is a widely used new type of valve, which has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable, the sealing surface material of gate valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy to maintain, the gate valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.

When fully open or fully closed, the sealing surfaces of the valve body and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. Electric flange globe valves have a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball rotates 90 degrees, it should appear spherical at both the inlet and outlet to intercept the flow.
