Piston valve welcomes your call to inquire!

The plunger valve is composed of the valve body, bonnet, valve stem, plunger, hole frame, sealing ring, handwheel and other parts. When the handwheel rotates, pass.

The valve stem drives the plunger to reciprocate up and down in the middle of the hole frame to complete the opening and closing functions of the valve. Opening and closing parts of the globe valve.

It is a plug-shaped disc with a flat or cone sealing surface that moves in a straight line along the center line of the fluid.

The closing of the plunger valve consists of a stainless steel plunger, two elastic seals on the top and bottom and a metal spacer.

It is achieved by the close cooperation of the plunger and the sealing ring, the plunger is inserted in two sealing rings, and the sealing area is much larger than that of the ordinary globe valve;

When the plunger valve is opened and closed, the plunger moves slowly in the sealing ring, the contact surface is almost non-wearable, and when closed, the plunger is inserted into the lower seal.

Ring, truncated runner; When opened, the plunger is detached from the lower seal, but it is still hidden in the upper seal, keeping it isolated from the outside world.

No leakage. The shut-off valve is a forced-tight valve, so when the valve is closed, pressure must be applied to the disc.

In order to force the sealing surface not to leak. When the medium enters the valve from under the disc, the resistance that needs to be overcome by the operating force is the valve.

The friction between the rod and the packing is greater than the force of opening the valve with the thrust generated by the pressure of the medium, so the valve stem.

The diameter of the valve should be large, otherwise the failure of the stem top bend will occur.

1. What is a plunger valve The plunger valve is composed of a valve body, valve cover, valve stem, plunger, hole frame, sealing ring, handwheel and other parts. When the handwheel rotates, the plunger is driven by the valve stem to reciprocate up and down in the middle of the hole frame to complete the opening and closing function of the valve. Second, the working principle of the plunger valve The closing of the plunger valve is composed of a stainless steel plunger, two elastic sealing rings and a metal partition, the sealing effect is achieved by the close cooperation between the plunger and the sealing ring, the plunger is inserted in the two sealing rings, and the sealing area is much larger than that of the ordinary globe valve; When the plunger valve is opened and closed, the plunger moves slowly in the sealing ring, and the contact surface is almost not worn, and when it is closed, the plunger is inserted into the lower sealing ring to cut off the flow channel; When opened, the plunger is detached from the lower seal, but it is still hidden in the upper seal, keeping it isolated from the outside world and preventing leakage.

The article refers to the introduction here.

First, the principle of the plunger valve

The opening and closing system of the plunger valve is mainly composed of a plunger and two sealing rings, when the plunger is rotated to open the plunger valve, the plunger slowly moves upward, inserts it in the middle of the sealing ring, and opens the flow channel; When closed, the plunger moves downwards and inserts into the seal underneath to intercept the flow path and remain isolated from the outside world without leakage.

Second, the manufacturer of piston valves

1. Cool Pump and Valve Manufacturing.

Cool Pump & Valve Manufacturing **** is located in Songjiang District, Shanghai, is a company specializing in research and development, production and sales of various pump and valve equipment, the main products are sewage pumps, centrifugal pumps, plunger valves, etc., the company since its inception, from the introduction of advanced technical personnel from major universities, and in every aspect of equipment production, strict management of quality, is committed to producing high-quality products in a harsh environment.

2. Gongzhou valve.

Gongzhou valve **** is located in Fengxian District, Shanghai, the company from the early days of the introduction of very advanced processing and quality inspection technology from Taiwan, strict management of product quality, and strive to provide customers with satisfactory valve products. The company strives to reduce the cost of investment under the premise of ensuring product quality and quality, so as to be able to provide customers with more high-quality and low-cost equipment products.

3. The old lathe valve ****.

Located in Liaocheng City, Shandong Province, the company is committed to R&D, production, processing and sales of various valve equipment, the company has accumulated a very rich practical experience and broad network of contacts in the course of many years of development, laying a very good foundation for the future development. At the same time, in terms of product quality and service, it has also won the recognition and support of new and old customers.

3. The difference between a piston valve and a globe valve

1. The plunger valve relies on the up and down movement of the plunger to complete the opening and closing of the whole valve, and the interception element of the globe valve is a valve disc, and the linear movement is done along the direction of the fluid to complete the opening and closing of the valve

2. The sealing area and effect of the plunger valve are much larger than those of the globe valve

3. The plunger valve can adjust the flow to a certain extent, but the globe valve can only play the role of opening and closing the valve.

The specific steps for the use of the plunger valve are as follows:

1. Cut off the fluid upstream of the plunger valve, so that the valve to be repaired (hereinafter referred to as the valve) no longer has fluid flowing through, and open the valve (all open);

2. Remove the plunger valve nut, rotate the handwheel in the closing direction, and bring the valve cover out

3. When the bonnet stud hole is separated from the stud bolt, turn the bonnet around the stem at a small angle, so that the bottom of the bonnet flange faces the stud bolt head

4. Rotate the piston valve handwheel in the opposite direction, let the valve cover against the stud bolt, and continue to reverse the handwheel until the plunger pulls out the upper sealing ring

5. Use the plunger valve extractor to take out the upper sealing ring and the partition frame, and use the driver to take out the lower sealing ring

6. Replace the old sealing ring with a new sealing ring, and install it into the valve body in the order of the lower sealing ring-partition frame-upper sealing ring

7. After wiping the inner surface of the sealing ring and the outer surface of the plunger, put the plunger in place together with the bonnet and stem, screw on the nut, and press the end face of the bonnet on the upper sealing ring

8. Twist the handwheel in the closing direction and press the plunger into the sealing ring.
