Description
Technical field
The present invention relates to field of fluid control, and in particular to a kind of easy rotation is so as to switch the valve of pipeline.
Background technology
Valve is in fluid system, for controlling fluid (liquid, gas, powder) to continue or stop in correspondence pipeline
The device of flow forward.State of the change fluid in pipeline is controlled to be changed into stopping flow forward from continuation flow forward,
Or, it is necessary to rotated to valve when from stopping flow forward being changed into continuing flow forward, change its inner flow passage relative to
The direction of pipeline is realized.
As shown in figure 1, traditional valve is sphere structure, pressure (air pressure, the hydraulic pressure that fluid is produced in body are being run into
Deng) it is larger when, larger resistance can be produced to valve, when changeover valve to its inner flow passage and pipeline are tilted, fluid can be right
The inwall of runner produces a pressure, a component F of the pressure1The resistance for continuing changeover valve can be turned into, cause continuation to be revolved
Rotary valve door can be highly difficult, causes to switch pipeline by changeover valve gruelling.
The content of the invention
In summary, to overcome the deficiencies in the prior art, the technical problems to be solved by the invention are to provide a kind of easy
Rotation is so as to switch the valve of pipeline.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of easy rotation so as to switch the valve of pipeline,
Including, in spherical body, the body interior is axially arranged with side on the runner run through, the body in pipeline
Provided with being rotated for the pressure by fluids within pipes so as to close the first breach of pipeline, the body opposite side is provided with
Its opposite direction is rotated by the pressure of fluids within pipes to open the second breach of pipeline, and first breach and institute
The second breach is stated to be respectively on described body sidewall and at the position at the correspondence runner two ends；First breach includes straight
Face and inclined-plane, described face directly are joined together to form the breach on described body sidewall, and institute with the side on the inclined-plane
State the angle faced directly between the inclined-plane and be less than 90 °.
The beneficial effects of the invention are as follows：The valve is provided with to be rotated to close pipeline by the pressure of fluids within pipes
The first breach, be additionally provided with the pressure by fluids within pipes and rotate its opposite direction so as to open the second breach of pipeline, from
And the resistance of changeover valve generation is reduced, easy changeover valve switchs pipeline, and the first breach and the second breach include one
Individual inclined-plane, valve rotate during Fluid pressure inclined-plane will not be had an effect, Fluid pressure concentrate on the first breach and
Second breach is faced directly, so that the resistance that preferably reduction changeover valve is produced.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement：
Further, second breach is consistent with the structure of first breach.
Further, run through above and below the axial direction of first breach and second breach along the body.
Beneficial effect using above-mentioned further scheme is：Fluid pressure acts on flat on the first breach or the second breach
The surface area in face is bigger, and increase fluid is to the first breach or the pressure of the second breach, so as to overcome what more changeover valves were produced
Resistance, it is easier to which changeover valve switchs pipeline.

Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in Figures 2 and 3, a kind of easy rotation is so as to switch the valve of pipeline, including interior in pipeline 1 is in spherical sheet
It is axially arranged with the runner 3 run through inside body 2, the body 2, it is characterised in that side, which is provided with, on the body 1 is used to borrow
The pressure of fluid in pipeline 1 is helped to be rotated so as to close the first breach 4 of pipeline 1, the opposite side of body 1 is provided with by pipe
The pressure of fluid rotates its opposite direction to open the second breach 5 of pipeline 1 in road 1, and first breach 4 and described
Second breach 5 is respectively on the side wall of body 2 and at the position at the correspondence runner two ends.First breach 4 and institute
State and run through above and below axial direction of second breach 5 along the body 2, preferably：Second breach 5 and first breach
4 structure is consistent.First breach 4 includes facing 6 and inclined-plane 7 directly, it is described face directly 6 and the side on the inclined-plane 7 be connected to one
The breach formed on the side wall of body 2 is acted, and the angle faced directly between 6 and the inclined-plane 7 is less than 90 °.In valve
Fluid pressure will not have an effect to inclined-plane during door rotation, and Fluid pressure concentrates on the straight of the first breach and the second breach
Face, so that the resistance that preferably reduction changeover valve is produced.
Close pipeline 1 and changeover valve unlatching pipeline 1 respectively to illustrate below by changeover valve：
As shown in figure 4, runner 3 opens pipeline 1 in coaxial state, i.e. valve with body 1.Now, pipeline 1 is closed
Need along direction of arrow rotating body 2.When most starting rotation, Fluid pressure F is acted in a plane of the first breach 4,
Because pressure F direction and the direction of changeover valve are consistent, as long as so less power just can make it along general with turn valve
The direction that pipeline 1 is closed is rotated.
Continue changeover valve to position as shown in Figure 5, when the runner 3 on body 2 and the inclination of pipeline 1, fluid can be right
The inwall of runner 3 produces a pressure, a component F of the pressure1The resistance for continuing changeover valve can be turned into.And it is same with this
When, fluid can also produce pressure, a component F of the pressure to a plane of the first breach 42Just with F1It is in opposite direction,
So as to overcome the resistance for continuing changeover valve, remain in that less power just can be with turn valve, until valve is by pipeline 1
Untill closing.
As shown in fig. 6, runner 3 closes pipeline 1 in Axis Cross plumbness, i.e. valve with body 1.Now,
Opening pipeline 1 needs along direction of arrow rotating body 2.When most starting rotation, Fluid pressure F acts on the one of the second breach 5
In individual plane, because pressure F direction and the direction of changeover valve are consistent, as long as so less power just can with turn valve,
It is set to be rotated along the direction for opening pipeline 1.
It is same as above, continue changeover valve when the runner 3 on body 2 and the inclination of pipeline 1, fluid is to the second breach 5
One plane can produce pressure, and a component of the pressure can overcome the resistance for continuing changeover valve, remain in that less
Power just can be with turn valve, untill valve opens pipeline 1.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
