Abstract
The invention discloses the sealing surface fluid erosion prevention device positioned at drain pipe chamber side on a kind of valve body, including pipe (1), holds out against screw (2), pipe (1) inwall is formed with several spiral depressions (3), the pipe (1) is real similar to gun barrel, each described depression (3) depth, width is 1.0 1.5 millimeters, the pipe (1) is filled in the feed liquor tube chamber of valve body (4), pipe (1) wall has screwed hole, and the screw (2) holds out against the feed liquor lumen wall of valve body (4) through the screwed hole.Because the pipe (1) inwall is formed with several spiral depressions (2), when opening state entirely at the door lock, liquid stream passes through valve body (4) inner chamber in rotary manner, liquid stream is cylindrical during outflow rushes at the drain pipe chamber, it is to avoid the sealing surface positioned at drain pipe chamber side on erosion valve body (4).
Description
Technical field
The invention belongs to valve protection device, more specifically to the sealing positioned at drain pipe chamber side on a kind of valve body
Face fluid erosion prevention device.
Background technology
A kind of existing gate valve includes handle, and valve body, door lock, the valve body and the door lock respectively have two sealing surfaces, when
The sealing surface positioned at drain pipe chamber side when opening state at the door lock entirely on the valve body is easily by the feed liquor tube chamber from the valve body
The erosion in round table-like liquid stream gone out, so that valve closing is not complete, leakage.Therefore it provides being located at drain pipe chamber on a kind of valve body
The sealing surface fluid erosion prevention device of side, tool is of great significance.
The content of the invention
It is an object of the invention to provide the sealing surface fluid erosion prevention device positioned at drain pipe chamber side on a kind of valve body.
The sealing surface fluid erosion prevention device positioned at drain pipe chamber side on a kind of valve body of the present invention, including pipe, holds out against screw,
The tube wall is formed with several spiral depressions, and the pipe plug has screw thread in the feed liquor tube chamber of valve body, the tube wall
Hole, the screw holds out against the feed liquor lumen wall of valve body through the screwed hole.
The following beneficial effect of present invention tool：
The pipe plug is in after the feed liquor tube chamber of valve body, because the tube wall is formed with several spiral depressions, when
When opening state entirely at the door lock, liquid stream passes through body cavity in rotary manner, during outflow liquid stream it is cylindrical rush at it is described go out
Liquid pipe chamber, it is to avoid the sealing surface positioned at drain pipe chamber side on erosion valve body.
Brief description of the drawings
Fig. 1 is the structural representation of the sealing surface fluid erosion prevention device positioned at drain pipe chamber side on a kind of valve body of the invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1, the sealing surface fluid erosion prevention device positioned at drain pipe chamber side on a kind of valve body, including pipe 1, hold out against spiral shell
Silk 2, the inwall of pipe 1 is formed with several spiral depressions 3, and the pipe 1 is real similar to gun barrel, and the depression 3 is generally
Four to six, 3 depth of each depression, width is 1.0-1.5 millimeters, and the pipe 1 fills in the feed liquor tube chamber in valve body 4, institute
Stating the wall of pipe 1 has screwed hole, and the screw 2 holds out against the feed liquor lumen wall of valve body 4 through the screwed hole.
The pipe 1 is preferably made of plastic.
