Example Embodiment

[0012] The present invention will be described below with reference to the drawings.

[0013] Attached figure 2 The sealing device according to the present invention includes a central body 1 and an air chamber end cover 2. The central body 1 and the air chamber end cover 2 are respectively provided with a first through hole 3 and a second through hole 4, and bolts 5 are used. It is connected and fixed with a nut 6; the air chamber end cover 2 is provided with a groove 7 at the position of the second through hole 4, and a sealing ring 8 is arranged in the groove 7.

[0014] The groove 7 is arranged on the side of the air chamber end cover 2 away from the central body 1. .

[0015] During the use of the sealing device of the present invention, the bolt 5 and the air chamber end cover 2 are completely sealed by the sealing ring 8 provided in the groove 7, which effectively improves the center body 1 and the air chamber end cover The tightness of the fixed connection between 2 impro...

Abstract

The invention discloses a sealing device which comprises a central body and an air chamber end cap. The central body and the air chamber end cap are provided with a first through hole and a second through hole respectively and fixed through a bolt and a nut connectedly, the air chamber end cap is provided with a groove at the position of the second through hole, and a sealing ring is arranged in the groove. When the sealing device is in use, space between the bolt and the air chamber end cap is completely sealed by the sealing ring arranged in the groove, so that sealability of connected fixing between the central body and the air chamber end cap is effectively improved and sealability of a pneumatic diaphragm pump is improved.

Description

technical field [0001] The invention relates to a sealing device used on a pneumatic diaphragm pump. Background technique [0002] Existing technology as attached figure 1 The connection between the central body 1 and the air chamber end cover 2 is also fixed by the cooperation between the bolt 5 and the bolt 6. Since the air flow exists in the central body 1 and the air chamber end cover 2, the bolt 5 and the central body There is inevitably a gap between the first through hole 3 in 1 and the second through hole 4 in the air chamber end cover 2, so that the gas in the pneumatic diaphragm pump leaks and forms a flow, which in turn makes the transported liquid permeate . Contents of the invention [0003] In view of the above-mentioned existing technical problems, the object of the present invention is to propose a sealing device. [0004] The technical solution of the present invention is achieved as follows: a sealing device, including a central body and an air chamber...
