Description
Technical field
The present invention relates to a kind of self-adjustable gate valves, are specifically related to a kind of self-adjustable gate valve.
Background technology
Existing gate is shut off by rotary valve rod realization mostly, but gate valve internal structure is simple, freezes it in pipeline
Afterwards, it is squeezed inside gate valve, component may be damaged, while sealing performance is not very good.
Invention content
The technical problem to be solved by the present invention is to overcome the prior art gate valve inner body impaired, leakproofness that is squeezed to wait carrying
The defect risen, provides a kind of self-adjustable gate valve.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of self-adjustable gate valve, including valve
Body, the left side integrally connected water inlet of the valve body, the right side integrally connected water outlet of the valve body open up circle in the valve body
The cavity of column structure, the cavity is interior to install the column that shuts off, and the bottom of the cavity is fixedly connected with movable block, and the movable block is lived
The lower end of dynamic connection column, the upper end of the column are fixedly connected with the lower end for the column that shuts off, and the upper end of the column that shuts off integrally connects
Valve rod is connect, runs through on the column that shuts off and opens up to recirculation hole, the both sides of the valve body, which are run through, opens up connection inlet and outlet
Conduit, the both sides of the column that shuts off are installed arc plate, are fixedly connected by rubber strip between the avris and the column that shuts off of the arc plate；
The length of the column that shuts off is more than the notch path length of conduit；The conduit is oblique.
Further, it is fixedly connected by spring between the inside of the arc plate and the column that shuts off.
The present invention has an advantageous effect in that compared with prior art：A kind of self-adjustable gate valve, it is reasonable for structure, make
With conveniently, the internal structure of gate valve is mainly improved, is allowed to be squeezed and can be realized while reserved space with reserved space
Shut off, and good airproof performance, it is safe, there is double sealing effect.

Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to figs. 1 to known to Fig. 2：A kind of self-adjustable gate valve, including valve body 1, the left side of the valve body 1 integrally connect
Tap into the mouth of a river 2, the right side integrally connected water outlet 3 of the valve body 1 opens up the cavity 4 of cylindrical structure, institute in the valve body 1
It states and the column 5 that shuts off is installed in cavity 4, the bottom of the cavity 4 is fixedly connected with movable block 6, and the movable block 6 is flexibly connected column 7
Lower end, the upper end of the column 7 is fixedly connected with the lower end for the column 5 that shuts off, the upper end integrally connected valve rod 8 of the column 5 that shuts off,
Through opening up to recirculation hole 9 on the column 5 that shuts off, the both sides of the valve body 1, which are run through, opens up connection water inlet 2 and water outlet 3
Conduit 10, the both sides installation arc plate 11 of the column 5 that shuts off, by rubber strip 12 between the avris of the arc plate 11 and the column 5 that shuts off
It is fixedly connected.
The notch path length that the length of the column 5 that shuts off is more than conduit 10 prevents spilling water convenient for shutting off；The conduit 10 is in
It is skewed, it is skidded off downwards convenient for water after shutting off, avoids valve internal water accumulation；Pass through bullet between the inside of the arc plate 11 and the column 5 that shuts off
Spring 13 is fixedly connected, and rubber strip 12 damages, and can resist arc plate 11.
The principle of the present invention and advantage：In use, operation handwheel, rotation valve rod 8, the column 5 that shuts off rotates with, when the column that shuts off
When 5 recirculation hole 9 is connected to conduit 10, water inlet 2 is connected to the realization of water outlet 3, realizes water outlet at this time, again rotation hand wheel,
Shut off the recirculation hole 9 of column 5 and conduit 10 is staggered, realization is shut off, and arc plate 11 closes water inlet 2 and water outlet 3 at this time, works as water inlet
2 or water outlet 3 when freezing, ice body can squeeze arc plate 11, and rubber strip 12, which is shunk, generates gap, and ice body is given to expand reserved space, when
Rubber strip 12 in gate valve damages, and arc plate 11 can be squeezed and be fitted in cavity by arc plate 11 and the disconnection of column 5 of shutting off, the then stretching, extension of spring 13
On 4 side walls, leak is prevented.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
