Embodiment Construction

[0016] In the valve assembly process of this embodiment, the valve includes a valve body 11, a valve core 5 with a valve stem 1, a rear valve stem 9, an upper gland 3 and a lower gland 8, and the valve core 5 can be O-shaped The spool, the following steps are used during assembly: first take the valve body 11 and the spool 5 with the valve stem 1 and the rear valve stem 9; place the sealing seat 10 in the cavity of the valve body 11; put the valve core 5 The rod 1 extends into the cavity of the valve body from the side of the valve body 11, reaches a proper position, and rotates the valve core in the vertical direction, so that the valve rod 1 on the valve core 5 protrudes above the valve body 11, and at the same time seals The seat 10 is set on the valve stem 1, and then continue to push the valve core 5, so that the valve core 5 is completely placed in the cavity of the valve body 11, and then the rear valve stem 1 is extended through the through hole at the bottom of the val...

Abstract

The invention discloses an assembly technology of a valve, which is characterized by comprising the following steps: taking a valve body (11), a valve core (5) with a valve rod (1), and a back valve rod (9); the assembly process comprises the following steps: firstly arranging a sealing seat (10) in the cavity of the valve body; extending the valve rod of the valve core into the cavity of the valve body from the side surface of the valve body; when the valve rod reaches a proper position, rotating the valve core in the vertical direction to enable the valve rod on the valve core to extend above the valve body; then extending the valve rod into a lower axle sleeve (6) at the bottom of the valve core through a through hole at the bottom of the valve body, and fixing and positioning a back pressing cover (8) on the back valve rod; sleeving an upper pressing cover (3) with an upper axle sleeve (2) into the valve rod and then fixing at the valve body; and finally, fixing a sealing end cover (4) with the valve body and assembling the valve core in the valve body. The assembly technology of the valve changes the traditional technology that the valve core of the valve is inserted into the cavity of the valve body from the top of the valve body, thus the volume of the valve body is reduced, and the sealing performance of the valve body is good after the assembling process is finished.

Description

technical field [0001] The invention relates to a valve assembly process. Background technique [0002] At present, the structure of the valve includes a valve stem, a valve core, a valve body, a rear valve stem, an upper gland and a rear gland. When assembling this valve, the valve stem is first fixed on the valve core, and then the valve The core is inserted into the cavity of the valve body from top to bottom, and then the sealing seat is set on the valve core, and then the rear valve stem is installed, and the lower gland and the upper gland are assembled, and the assembly is completed. This assembly method must make the valve body large enough, otherwise, the valve core cannot be inserted into the cavity of the valve body from top to bottom. Therefore, the valve of this assembly method has a large volume, which is a kind of material. waste. And its sealing performance is not good enough. Contents of the invention [0003] In view of the deficiencies in the backgrou...
