First, the use of track plug valve
The track plug valve (named general valve) is suitable for the pipeline of various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, electric power industry, etc. with nominal pressure CLASS150-900LBS, working temperature -29-180 °C, cutting or connecting the pipeline medium. .

Second, the main structural characteristics of the track plug valve
1 During the switching process, the sealing surface of the valve body does not have any contact with the sealing surface of the sliding plate. Therefore, the sealing surface has no friction, wear, long service life of the valve, and small switching torque;
2 When the valve is being repaired, it is not necessary to remove the valve from the pipeline. It is only necessary to disassemble the bottom cover of the valve and exchange a pair of slides. The maintenance is very convenient;
3 valve body and cock are full-diameter, the medium has no flow resistance when passing through the valve, and can clean the pipeline through the ball, overcoming the shortcomings of the reduced-diameter valve;
4 full-bore general valve valve body cavity is plated with hard chrome, the sealing area is hard and smooth;
The elastic seal on the slide is made of fluororubber and molded into the groove on the surface of the slide. Metal-to-metal seal with fire protection as a resiliently sealed backing;
The 6 valve has an automatic bleed device (optional) that prevents the valve chamber from abnormally boosting and verifying the effect of the valve after the valve is fully closed;
7 The valve switch indicator is synchronized with the switch position, which can accurately display the switch state of the gear transmission full-path general valve.

Third, the working principle of the track plug valve
1. When the valve is fully open, the passage of the plug's passage valve body is aligned to ensure the ideal minimum pressure drop.
2. When turning the handwheel, the plug will rotate in the direction of the valve, and at the same time drive the valve to rotate 90 degrees. When the handwheel is continued to rotate, the plug will be pressed down, the valve will open to the sides, and the valve will be tightly pressed. On the seat, close the valve.
3. When the hand wheel rotates in the opposite direction, firstly move the plug upwards to disengage the valve piece from the valve seat, continue to rotate the hand wheel, so that the plug drives the valve piece to rotate 90 degrees, and finally the passage of the plug is aligned with the passage of the valve body. Leave the valve fully open.
4. The advantage of this valve is that the valve and the valve seat are in the disengaged state during the opening process, the process of the switch is zero friction, the sealing surface is not worn, and the seal is soft sealed, so that the seal is zero when closed. Give way.
