Description

Simple butterfly valve

Technical Field

The utility model relates to a simple and convenient nature butterfly valve.

Background

The ball valve, the half ball valve and the butterfly valve are used in a fluid conveying pipeline, particularly water conveying pipelines, the ball valve, the half ball valve or the butterfly valve are respectively provided with a valve body and a valve core, a sealing pair is arranged between the valve body and the valve core, and the valve body and the valve core are tightly attached through the sealing pair so as to realize the sealing between the valve core and the valve body.

When the butterfly valve needs to be opened, the butterfly valve is often opened or closed by rotating the valve rod by 90 degrees, but the existing butterfly valve is often not firm in sealing when closed, and leakage and other situations are easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, and providing a simple butterfly valve.

The utility model provides a simple and convenient nature butterfly valve, includes the valve body and stretches out the outer valve rod of valve body, the top of valve body is equipped with the supporting seat, valve rod and supporting seat between link to each other through the torsional spring, the hasp include annular lock body, annular lock body's the outside even has outer buckle, annular lock body's inboard even has interior buckle, outer buckle and the draw-in groove on the supporting seat inner wall match, interior buckle and the draw-in groove on the valve rod outer wall match.

Preferably, the top end of the lock catch is connected with an arc-shaped handle.

Preferably, the torsion spring is a stainless steel torsion spring.

Preferably, the valve rod is made of hard aluminum alloy.

Preferably, the valve rod is connected with the supporting seat through a bearing.

Preferably, the inner buckle and the outer buckle are distributed in a right angle, and the widths of the inner buckle and the outer buckle are equal.

Has the advantages that:

1. through the effect of torsional spring, can guarantee that the valve rod receives a power of shutting tightly all the time, prevent that the case is not hard up to lead to the emergence of the valve leakage condition, and the setting of torsional spring can also promote the sealed effect of whole ball valve to when not needing to use, automatic with the inside rotating of valve rod, close the valve, prevent that the water in the pipeline from being extravagant by a large amount.

2. The hasp is used for pinning valve rod and supporting seat, and when the valve rod was rotated to needs, only need through rotatory hasp, because the interior buckle of hasp and the draw-in groove looks joint on the valve rod outer wall this moment can drive the valve rod rotation to change the state of opening and shutting of valve.

3. This device is simple and practical, can be used to the tap setting of outdoor running water, and the setting of special hasp can prevent to be stolen the emergence of using the phenomenon by the people, and even the quilt opens the valve with other instruments, when external force disappearance back, also can be under the effect of torsional spring, rapid with the valve close, only use hasp joint supporting seat and valve rod simultaneously, just can keep the valve to be in normally open state.

FIG. 2 illustrates a second use state of a simple butterfly valve;

1. the valve body 2, the supporting seat 3, the torsion spring 4 and the lock catch.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1-2, a simple butterfly valve, includes valve body 1 and stretches out valve rod 5 outside valve body 1, the top of valve body 1 is equipped with supporting seat 2, valve rod 5 and supporting seat 2 between link to each other through torsional spring 3, hasp 4 include annular lock body, annular lock body's the outside even has outer buckle, and annular lock body's inboard even has interior buckle, outer buckle and the draw-in groove on the 2 inner walls of supporting seat match, interior buckle and the draw-in groove on the 5 outer walls of valve rod match, the top of hasp even has the arc handle, the torsional spring be the stainless steel torsional spring, valve rod 5's material is the stereoplasm aluminum alloy, link to each other through the bearing between valve rod 5 and the supporting seat.

This device is simple and practical for the tap setting of outdoor running water, dedicated hasp design can prevent to be stolen the usefulness by the people, even the quilt opens the valve with other instruments, after external force disappears, also can be under torsional spring 3's effect, rapid with the valve close, only use 4 joint supporting seats 2 and valve rod 5 simultaneously of hasp, just can keep the valve to be in normally open state. Therefore, the tap water can be prevented from being stolen on the one hand and can be prevented from being wasted in a large amount on the other hand outdoors.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
