Because the sealing ring is arranged at the joint, the sealing property of the connection between the valve body and the valve cover is greatly improved. The gate valve with the middle sealing structure is simple in structure, obvious in effect, low in cost and high in practicability.)

1. The utility model provides a take middle seal structure's gate valve, a serial communication port, take middle seal structure's gate valve (1) contain a valve body (2) and a valve gap (3), valve gap (3) detachably with valve body (2) be connected, the center of valve body (2) be equipped with a case (4), the top of valve body (2) be equipped with an annular sealed annular (21), sealed annular (21) in be equipped with a detachable sealing washer (5).

2. The gate valve with the intermediate sealing structure according to claim 1, wherein the sealing ring (5) is an O-ring.

Technical Field

The invention relates to a valve, in particular to a gate valve with an intermediate sealing structure.

Background

The valve wheel of the existing gate valve generally adopts a split structure and is connected by bolts, and the sealing performance of the joint is poor.

Disclosure of Invention

The invention mainly solves the technical problems in the prior art, and provides a gate valve with an intermediate sealing structure.

The technical problem of the invention is mainly solved by the following technical scheme:

the utility model provides a take middle seal structure's gate valve, its characterized in that, take middle seal structure's gate valve contain a valve body and a valve gap, valve gap detachably with the valve body be connected, the center of valve body be equipped with a case, the top of valve body be equipped with an annular sealed annular, sealed annular in be equipped with a detachable sealing washer.

As a preferred embodiment of the present invention, the sealing ring is an O-ring.

The gate valve with the intermediate sealing structure has the following advantages: when in use, the sealing ring is arranged at the joint, so that the sealing property of the connection between the valve body and the valve cover is greatly improved. The gate valve with the middle sealing structure is simple in structure, obvious in effect, low in cost and high in practicability.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.

As shown in fig. 1 to 5, the gate valve 1 with the middle sealing structure comprises a valve body 2 and a valve cover 3, wherein the valve cover 3 is detachably connected with the valve body 2, a valve core 4 is arranged at the center of the valve body 2, an annular sealing ring groove 21 is arranged at the top of the valve body 2, and a detachable sealing ring 5 is arranged in the sealing ring groove 21.

The sealing ring 5 is an O-ring.

When in use, the sealing ring 5 is arranged at the joint, so that the sealing property of the connection between the valve body 2 and the valve cover 3 is greatly improved.

The gate valve with the middle sealing structure is simple in structure, obvious in effect, low in cost and high in practicability.

Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
