Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Reference numerals: 1, a valve cover; 2, a baffle ring; 3.1 a first seal ring; 3.2 a second sealing ring; 4, a rubber expansion piece; 4.1 a first end ring; 4.1 second end ring; 4.3 rubber parts; 5, a valve body; 5.1 air pipe joint; 6.1 first bolt; 6.2 second bolt; 6.3 third bolt; 7, a second mounting flange; 8, a fourth bolt; 9 mounting seats; 9.1 a cylinder body; 9.2, a first mounting flange; 10 concrete wall.

The following detailed description is made with reference to the accompanying drawings: a high-efficiency sealing pneumatic valve comprises a valve body 5, a rubber expansion piece 4, a valve cover 1, a baffle ring 2, a first sealing ring 3.1, a second sealing ring 3.2, a first bolt 6.1, a second bolt 6.2 and a third bolt 6.3; the valve body 5 is provided with an air pipe joint 5.1, the rubber expansion piece 4 is installed in the valve body 5, the rubber expansion piece 4 comprises a first end ring 4.1, a second end ring 4.2 and a rubber piece 4.3 connecting the first end ring 4.1 and the second end ring 4.2, the first bolt 6.1 fixedly connects the baffle ring 2, the first sealing ring 3.1 and the first end ring 4.1, and the second bolt 6.2 fixedly connects the valve cover 1, the baffle ring 2 and one end of the valve body 5; the other end of the valve body 5, the second sealing ring 3.2 and the second end ring 4.2 are fixedly connected by the third bolt 6.3.

The rubber part 4.3 is integrally formed by cloth-sandwiched rubber. The first bolt 6.1, the second bolt 6.2 and the third bolt 6.3 each have 6. The first end ring 4.1 and the second end ring 4.2 are both steel rings.
