What are the construction requirements for all-inclusive ball valves? Now let's take a brief analysis.

The ball is transformed from the plug valve, its center of the ball is rotated 90 action, the ball is rotated around the center line of the valve body to achieve the opening, there is a circular through the hole or channel through its axis. When the center of the ball is rotated to 90°, the valve is closed, and when the pneumatic actuator is working, the ball valve only needs a small torque to complete the valve closing action to achieve the purpose of rapid truncation.

What are the important requirements of the construction of the all-inclusive ball valve? It is a new type of product, which is equipped with a ball and a pneumatic actuator to replace the manual. The actuator drives the valve body to open and close quickly, and the speed can achieve the effect of second-level cutting. It is mainly divided into single acting type, double acting type and regulating type. The pneumatic head is equipped with triplet, positioner, limit switch and other accessories, which can be used as throttling to regulate flow. At the same time with a control box, a switch internal control can be carried out in a remote control room environment. Today, it has replaced many traditional handmade products, not only saving a lot of manpower and resources, but also controlling multiple projects at the same time. The structure is relatively simple, convenient maintenance management, relatively high safety, the selection of high-quality materials can be used properly, and the service life can reach 1 million times.

Ball valves have been widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rockets and other industries, as well as People's Daily life. The construction requirements for installing all-inclusive ball valves are as follows:

1. Careful installation and construction, do not hit the valve made of brittle materials.

2. Before installation, the stainless steel ball valve should be inspected, check the specifications and models, and identify whether there is damage, especially for the valve stem. It is also necessary to rotate a few times to see if it is skewed, because in the process of enterprise transportation development, it is easy to bump the valve stem. At the same time, remove debris from the valve.

3. When the ball valve is lifted, the rope should not be tied to the handwheel or valve stem to avoid damage to these components, and should be tied to the valve body.

4. For the pipeline connected to the valve, be sure to clean it.

5. Compressed air can be used to blow away iron oxide scraps, mud sand, welding slag and other debris. These debris, not only easy to scratch the sealing surface, including large particles of debris (such as welding slag), but also can block the ball valve and make it ineffective.

6. When installing the screw valve, the sealing filler (thread and lead oil or polytetrafluoroethylene raw material belt) should be wrapped on the pipe thread, do not get into the valve, so as to avoid valve memory accumulation and affect the flow of the medium.

7. When installing flange valves, pay attention to tighten the bolts symmetrically and evenly.

8. The flange is not parallel to the pipe flange, and the gap is reasonable to avoid excessive pressure and even cracking of the valve. For stainless steel ball valves with brittle materials and low strength, pay particular attention to the stainless steel ball valves welded with pipes, which should be spot-welded first, and then fully open the closing parts, and then welded dead.
