Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic valves, in particular to a pneumatic valve with replaceable sealing rings. Background Art

[0002] A pneumatic valve is a valve driven by compressed air and is widely used in various industrial fields, including machinery manufacturing, pneumatic industrial manipulators, complex production and manufacturing assembly lines, etc.

[0003] Currently, for the existing pneumatic valves to replace the sealing rings, the connection parts are disassembled and the sealing rings are directly replaced. Due to the long-term use of the sealing rings, the surface of the sealing rings is corroded, and some residues fall into the grooves. When replacing the new sealing rings, the inside of the grooves needs to be cleaned before the new sealing rings can be installed, which is time-consuming and laborious and affects the efficiency of replacing the sealing rings. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the existing residues falling from the sealing rings cannot be cleaned, resulting in time-consuming and laborious replacement and affecting the replacement efficiency, and to propose a pneumatic valve with replaceable sealing rings.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A pneumatic valve with replaceable sealing rings includes a pneumatic valve body. A connecting bracket is fixedly connected to the bottom of the pneumatic valve body. A ball valve is fixedly connected to the bottom end of the connecting bracket. Connecting pipes are arranged at both ends of the ball valve. The other end of each connecting pipe is fixedly connected to a second flange. A first flange is arranged on the other side of the second flange. The first flange and the second flange are fixed by bolts. An installation groove is arranged at one end of the second flange. A first notch is arranged on the circumferential inner wall of the installation groove. The first notch communicates with the connecting pipe. An installation ring is clamped in the installation groove. A sealing ring is sleeved on the outer wall of the installation ring. A second notch is arranged on the circumferential outer wall of the installation ring.

[0007] Further, a handwheel is inserted into one side of the pneumatic valve body.

[0008] Further, an anti-slip pad is bonded to the outer wall of the handwheel.

[0009] Further, one end of the ball valve and one end of one of the connecting pipes are connected by a flange.

[0010] Further, the other end of the ball valve and one end of the other connecting pipe are connected by welding.

[0011] Further, the first notch and the second notch are arranged opposite to each other.

[0012] The beneficial effects of the utility model are:

[0013] 1. By inserting a finger through the first notch into the second notch and then pulling the installation ring outwards, the installation ring and the sealing ring can be removed from the installation groove, which facilitates the replacement of the sealing ring and does not require cleaning of residues, saving time and effort.

[0014] 2. The sealing ring seals the ball valve and the connecting pipe, thus avoiding leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-3 , a pneumatic valve with a replaceable sealing ring, including a pneumatic valve body 1. A connecting bracket 3 is welded to the bottom of the pneumatic valve body 1. A ball valve 4 is welded to the bottom end of the connecting bracket 3. Connecting pipes 5 are provided at both ends of the ball valve 4. The other end of the connecting pipe 5 is welded with a second flange 7. A first flange 6 is provided on the other side of the second flange 7. The first flange 6 and the second flange 7 are fixed by bolts. An installation groove 8 is provided at one end of the second flange 7. A first notch 9 is provided on the circumferential inner wall of the installation groove 8. The first notch 9 communicates with the connecting pipe 5.
