Abstract
A kind of slideway rolling ball type line check valves, including valve body, valve gap, ball, the port of export that described valve body upper and lower end is respectively interconnected, entrance point, having cavity in valve body side, be positioned at the valve gap on the right side of cavity and be fixedly connected with the valve body by bolt, described ball is placed in described cavity, valve body is flexure plane near entrance point sidewall, its flexibility matches with described ball, and above described flexure plane, valve body cross section is fixedly installed a filter screen, and described filter screen has angle with vertical plane.By arrange in valve body one can roller ball, when this ball is rolled to fluid flowing passage, check-valves realizes cutoff function and prevents reverse flow of fluids, when this ball is rolled in cavity, fluid is normal through this stop valve, and compared with general check valve, this check-valves can be installed in the duct in a vertical manner.
Description
Technical field
This utility model relates to valve body technical field, is specifically related to a kind of check-valves.
Background technology
Check-valves refers to rely on medium itself to flow and automatic open and close flap, is used for the valve preventing medium from flowing backwards, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its Main Function is to prevent medium from falling
Stream, prevent pump and drive motor reversion, and the releasing of vessel media.Market upper check valve is all to be horizontally arranged at pipeline
In, due to flap self gravitation, this check-valves can not be arranged in vertical pipeline.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that a kind of slideway rolling ball type
Line check valves.
Technical problem to be solved in the utility model uses following technical scheme to realize:
A kind of slideway rolling ball type line check valves, including valve body, valve gap, ball, described valve body upper and lower end is respectively and interconnects mutually
The logical port of export, entrance point, had cavity in valve body side, be positioned at the valve gap on the right side of cavity and be fixedly connected with the valve body by bolt,
Described ball is placed in cavity, and valve body is flexure plane near entrance point sidewall, and its flexibility matches with ball, when ball is due to from heavy sensation of the body
Power is rolled to when valve body entrance point, and ball outer wall is just fitted with the flexure plane of body wall and made fluid not flow backwards, valve gap position
Being a flexure plane matched with ball in cavity mid portion, above flexure plane, valve body cross section arranges a filter screen, and filter screen is with perpendicular
Facing directly and have angle, when fluid flows into from entrance point, drive ball to be rolled in cavity, fluid flows out from the port of export, on cavity
On side's valve interior wall, a block is set, is possible to prevent ball shock issuable to filter screen in cavity, described ball preferably sky
Bulbus cordis, its material can be metal or plastics, in order to avoid fluid is by producing bigger resistance during this check-valves.
The beneficial effects of the utility model are: by arrange in valve body one can roller ball, when this ball be rolled to fluid flowing
During passage, check-valves realizes cutoff function and prevents reverse flow of fluids, and when this ball is rolled in cavity, fluid is normal through this cut-off
Valve, compared with general check valve, this check-valves can be installed in the duct in a vertical manner.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face combines and is specifically illustrating, and this utility model is expanded on further.
As it is shown in figure 1, a kind of slideway rolling ball type line check valves, including valve body 1, valve gap 6, ball 7, valve body 1 upper and lower end divides
The port of export 3 that Wei not be interconnected, entrance point 2, have cavity 8, be positioned at the valve gap 6 on the right side of cavity 8 and pass through bolt in valve body 1 side
Fixing with valve body 1 and be connected, ball 7 is placed in cavity 8, and valve body 1 is flexure plane 5 near entrance point 2 sidewall, its flexibility and ball 7 phase
Coupling, when ball 7 is rolled near valve body 1 entrance point 2 due to self gravitation, ball 7 outer wall just with the flexure plane 5 of valve body 1 sidewall
Laminating makes fluid not flow backwards, and it is a flexure plane matched with ball 7 that valve gap 6 is positioned at cavity 8 mid portion, on flexure plane 5
Valve body 1 cross section, side arranges a filter screen 4, and filter screen 4 has angle with vertical plane, when fluid flows into from entrance point 2, drives ball 7 to roll
To cavity 8, fluid flows out from the port of export 3, arranges a block 9, be possible to prevent ball 7 at sky above cavity 8 on valve body 1 inwall
Shock issuable to filter screen 4 in chamber 8, ball 7 preferably hollow ball, its material can be metal or plastics, in order to avoid fluid
By producing bigger resistance during this check-valves.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model
Claimed scope is defined by appending claims and equivalent thereof.
