Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically an integrated control ball valve. Background Technology

[0002] In modern chemical, aerospace, and transportation industries, various valves and instruments are frequently used, and ball valves are among the most popular due to their simple structure, good sealing performance, and light weight. However, existing ball valves typically use box-shaped packing seats with upper and lower mating parts, which cannot guarantee sealing performance. Furthermore, ball valves on the market often leak due to poor sealing, or rely on external sealing methods, which are detrimental to improving product performance. Moreover, few ball valves currently available have pneumatic automatic control functions; opening and closing are achieved only by manually turning a handwheel, resulting in extremely poor convenience, time-consuming and labor-intensive operation, and failing to meet the demands of comprehensive automatic control technology. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide an integrated control ball valve.

[0004] One of the objectives of this utility model is achieved through the following technical solution:

[0005] An integrated control ball valve includes a valve body, valve stem, valve seat, valve core, air filter pressure reducing valve, solenoid valve, and pneumatic actuator. The valve body has flanges on both sides and a valve core in the center. Valve seats are nested on both sides of the valve core. One side of the valve body has an end cap mounting interface. The end cap positions the valve seat on the same side and is tightened by an external thread structure on the outer periphery of the end cap engaging with an internal thread structure in the mounting interface. The valve stem is fixedly connected to the valve core and engages with an upper port in the middle of the valve body. A stuffing box is provided at the engagement point between the valve stem and the upper port. A connecting shaft is connected to the upper end of the valve stem, and a solenoid valve and the pneumatic actuator are connected to the connecting shaft. The solenoid valve is controlled by a signal from a central control room to open or close the valve. An air filter pressure reducing valve is externally connected to the solenoid valve. A bracket is provided at the bottom of the pneumatic actuator.

[0006] The pneumatic actuator has two connecting rods on its left side. The connecting rods are installed on the left side of the pneumatic actuator by a first bolt. A clamp is fixedly connected to the end of the connecting rod away from the pneumatic actuator.

[0007] Preferably, the two clamps are located on the front and rear sides of the air filter pressure reducing valve, and two second bolts are provided between the two clamps, which are connected to each other by the two second bolts.

[0008] Preferably, the connecting rod has a mounting hole that matches the first bolt.

[0009] Preferably, an anti-slip pad is fixedly connected to the inner side of the clamp, and the anti-slip pad is in contact with the outer side of the pneumatic actuator.

[0010] Preferably, the bottom of the bracket is locked to the outer periphery of the stuffing box by screws, thereby fixing the pneumatic actuator. The pneumatic actuator uses its elastic diaphragm to convert the air pressure input from the air compressor into a thrust on the push rod. The push rod causes the valve core to move accordingly, changing the valve opening and realizing self-control adjustment. A sealing ring is provided at the contact surface between the mounting interface and the valve body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model relates to an integrated control ball valve. The device replaces the original handwheel control valve rod rotation control ball valve opening and closing with a pneumatic actuator to achieve automatic opening and closing. It has a simple structure, low maintenance workload, and low equipment cost. The designed air filter pressure reducing valve sets the outlet pressure by adjusting the internal spring pressure. It uses a diaphragm to sense changes in outlet pressure and drives the piston through the opening and closing of the pilot valve to adjust the flow area of ​​the throttling part of the main valve, thereby achieving pressure reduction and stabilization. It is equipped with an installation interface and a mounting end cover, which makes the valve core installation simple, improves maintenance speed, and reduces maintenance costs.

[0013] 2. This utility model discloses an integrated control ball valve. The connecting rod is installed on the left side of the pneumatic actuator by cooperating with the first bolt through the mounting hole. At this time, two clamps are wrapped around the front and rear sides of the air filter pressure reducing valve. Then, the two clamps are fixed to the outside of the air filter pressure reducing valve by the second bolt. At this time, the air filter pressure reducing valve is supported and fixed on the pneumatic actuator by the clamps and the connecting rod, which improves the stability of the air filter pressure reducing valve and ensures the normal operation of the air filter pressure reducing valve.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an integrated control ball valve, including a valve body 1, a valve stem 4, a valve seat 2, a valve core 3, an air filter pressure reducing valve 12, a solenoid valve, and a pneumatic actuator 8. The valve body 1 has flanges on both sides and a valve core 3 in the center. The valve core 3 has valve seats 2 nested on both sides. The valve body 1 has an installation interface 13 for an end cap 11 on one side. The end cap 11 positions the valve seat 2 on the same side and is tightened by the external thread structure on the outer periphery of the end cap 11 and the internal thread structure in the installation interface 13. The valve stem 4 is fixedly connected to the valve core 3 and cooperates with the valve body upper port in the middle of the valve body 1. A stuffing box 5 is provided at the valve stem 4 and the valve body upper port.

[0024] The upper end of the valve stem 4 is connected to a connecting shaft 7, and a solenoid valve 9 and a pneumatic actuator 8 are connected to the connecting shaft 7.

The bottom of the pneumatic actuator 8 is provided with a bracket 6. The bottom of the bracket 6 is locked to the outer periphery of the stuffing box 5 by screws, thereby fixing the pneumatic actuator 8.

[0025] A further implementation scheme is that the pneumatic actuator 8 uses its elastic diaphragm to convert the air pressure input from the air compressor into a thrust on the push rod, which causes the valve core 3 to produce a corresponding displacement, thereby changing the opening degree of the ball valve and realizing self-control regulation.

[0026] A further embodiment is that a sealing ring 10 is provided at the contact surface between the mounting interface 13 and the valve body 1.

[0027] Two connecting rods 16 are provided on the left side of the pneumatic actuator 8. The connecting rods 16 are installed on the left side of the pneumatic actuator 8 by the first bolt 14.

The two clamps 15 are located on the front and rear sides of the air filter pressure reducing valve 12, respectively. Two second bolts 18 are provided between the two clamps 15, and the two clamps 15 are connected by the two second bolts 18. The connecting rod 16 has a mounting hole 17, which matches the first bolt 14. An anti-slip pad is fixedly connected to the inner side of the clamp 15, and the anti-slip pad is in contact with the outer side of the pneumatic actuator 8.

[0028] The connecting rod 16 is fitted with the first bolt 14 through the mounting hole 17, thereby installing the connecting rod 16 on the left side of the pneumatic actuator 8. At this time, the two clamps 15 are wrapped around the front and rear sides of the air filter pressure reducing valve 12. Then, the two clamps 15 are fixed to the outside of the air filter pressure reducing valve 12 by the second bolt 18. At this time, the air filter pressure reducing valve 12 is supported and fixed on the pneumatic actuator 8 by the clamps 15 and the connecting rod 16, which improves the stability of the air filter pressure reducing valve 12 and ensures the normal operation of the air filter pressure reducing valve 12.
