Embodiment Construction

[0028] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0029] Such as Figure 1-5 As shown, a soft-sealed gate valve with a conical seal includes a valve body 1, a bonnet 2, a valve stem 3, a rubber-coated gate 4 and a hand wheel 5;

[0030] The bonnet is fixedly connected to the valve body, and the valve stem and the rubberized gate are arranged inside the bonnet and the valve body; the valve stem runs through the bonnet and is fixed in the bonnet; The upper end opening of the valve cover protrudes and is fixedly connected with the hand wheel; the bottom of the valve stem is fixedly connected with the rubber-coated gate, preferably, the bottom of the valve stem is connected with the rubber-coated gate by screw transmission;

[0031] The sealing surface of the valve body is conical; the rubber-coated gate 4 includes a conical skeleton 401 and a soft rubberized layer 402; the upper part of the conical skele...

Abstract

The invention discloses a conical-sealed soft seal gate valve. The conical-sealed soft seal gate valve comprises a valve body, a valve cover, a valve rod, a rubber wrapping gate plate and a hand wheel; the valve cover is fixedly connected to the valve body; the valve rod and the rubber wrapping gate plate are both arranged in the valve cover and the valve body; the valve rod penetrates through the valve cover, and is fixed in the valve cover; the top end of the valve rod extends out from an upper end opening of the valve cover, and is fixedly connected with the hand wheel; the bottom of the valve rod is fixedly connected with the rubber wrapping gate plate; a sealing surface of the valve body is conical; the rubber wrapping gate plate includes a conical skeleton and a soft rubber wrapping layer; the upper part of the conical skeleton is a fixed part fixedly connected with the valve rod, and the lower part is a sealing part; and the soft rubber wrapping layer coats the lower surface of the conical skeleton, so that the soft rubber wrapping layer and the conical sealing surface of the valve body form soft seal. The gate valve can preferably solve the problems of loose sealing and leakage, and is a substitute good of a traditional gate valve.

Description

technical field [0001] The invention relates to the field of valve equipment used in plumbing, tap water, water supply and drainage, and more specifically, relates to a soft-seal gate valve with conical seal. Background technique [0002] In plumbing, water pipe network, water supply and drainage systems, after a period of use, many traditional gate valves on the market often have more or less lax valve closing and leakage, which has brought great harm to users. The troubles and damages of the environment have seriously affected people's lives and wasted precious water resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conical-seal soft-sealed gate valve, which can be A good solution to the problem of poor sealing and leakage, it is a substitute for traditional gate valves. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide a soft-sealed gate ...
