Problems solved by technology

[0003] like image 3 As shown, the sleeve valve sealing device in the prior art has only one sealing ring whose inner edge is bent upwards, so it can only prevent the outside water from entering the inner cavity of the sleeve, and the water in the inner cavity of the sleeve is easy to flow out, which cannot effectively Realize two-way sealing

Embodiment Construction

[0014] like figure 1 , figure 2 As shown in the structural diagram of the sleeve valve of the present invention, the sleeve valve of the present invention comprises an outer cylinder 1, an adjusting cylinder 2, a screw rod 20 and a hoist 21, the outer diameter of the adjusting cylinder 2 is smaller than that of the outer cylinder 1, and the outer cylinder 1 Inserting the adjusting cylinder 2, under the drive of the hoist 21 and the screw rod 20, the adjusting cylinder 2 can move up and down relative to the outer cylinder 1. A sealing device 22 is provided on the upper end of the outer cylinder 1. The sealing device 22 includes a flange 3, a gasket 9, a lower sealing ring 8, a gasket 7, an upper sealing ring 4, a pressure plate 5 and a bolt 6. The inner diameter of the flange 3 is the same as that of the outer cylinder 1. The outer diameter of the flange is adapted and welded on the outer cylinder 1, and the bolt 6 connects the flange 3, the gasket 9, the lower sealing ring ...

Abstract

The invention relates to a sleeve valve, comprising an outer cylinder (1), an adjusting cylinder (2) that can slide up and down in the outer cylinder (1), and a flange (3), A sealing device composed of an upper sealing ring (4) with an inner edge bent upward and a pressure plate (5), and a lower sealing ring with an inner edge bent downwards is also provided between the upper sealing ring (4) and the flange (3) (8). The invention can store more lubricating oil in the oil storage tank, and the sealing effect is better.

Description

technical field [0001] The invention relates to a valve, in particular to a sleeve valve. Background technique [0002] Sleeve valve, also known as lifting valve, is generally used in the sedimentation tank mud discharge well to discharge mud outside the pool. Because its structure is an inner and outer telescopic sleeve, it can also be used to adjust the water level in the water distribution well or the water outlet well, such as a single-pipe dredger Mud discharge, air flotation water discharge, etc., are generally made of carbon steel or stainless steel. However, since the lift pump is usually installed in the water distribution well, when the lift pump needs to be repaired for some reason, the sleeve valve is required to have a two-way sealing function, which can not only prevent water from flowing backward, but also prevent the water in the secondary settling tank from leaking into the drain. In the mud well, maintenance personnel can maintain the lift pump on the spot...
