Overview

The Huquan electric globe valve is a variation of the conventional electric globe valve. In this valve, the valve disc and seat are usually designed based on the plunger principle. The valve disc is polished into a plunger and connected to the valve stem, and the sealing is achieved by two elastic sealing rings fitted on the plunger. Two elastic sealing rings are separated by a ring, and the sealing ring around the plunger is pressed firmly by the load applied to the valve cover by the valve cover nut.

Product Details

Huquan electric globe valveThe closing principle of an electric globe valve is to rely on the electric thrust to rotate the valve stem, so that the sealing surface of the valve disc is tightly adhered to the sealing surface of the valve seat, preventing the flow of the medium. The electric globe valve only allows one-way flow of the medium and has directionality during installation. The structural length of the globe valve is greater than that of the gate valve, and the fluid resistance is high. During long-term operation, the sealing reliability is not strong.

1. Angle type electric globe valve; In the angle type electric globe valve, the fluid only needs to change direction once, so that the pressure drop through this valve is smaller than that of conventional structure electric globe valves.

2. DC electric globe valve; In DC or Y-shaped electric globe valves, the flow path of the valve body forms a diagonal line with the main flow path, which reduces the degree of damage to the flow state compared to conventional electric globe valves, and therefore reduces the pressure loss through the valve.

3. Piston type electric globe valve: This form of electric globe valve is a variation of conventional electric globe valves. In this valve, the valve disc and seat are usually designed based on the plunger principle. The valve disc is polished into a plunger and connected to the valve stem, and the sealing is achieved by two elastic sealing rings fitted on the plunger. Two elastic sealing rings are separated by a ring, and the sealing ring around the plunger is pressed firmly by the load applied to the valve cover by the valve cover nut.

Huquan electric globe valveIt 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, plastic is widely used as the sealing surface material for gate valves with good sealing performance, and it 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.

6. 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. Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications 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.
