Abstract
The invention relates to the technical field of a pipeline fitting, in particular to an anti-loosening valve. The anti-loosening valve comprises a valve body, a valve core and an adjusting rod, wherein the valve core is arranged in the valve body; the adjusting rod is connected to the valve core; a spring is arranged in the valve body and sleeves the adjusting rod; the two ends of the spring are clamped between the valve body and the valve core. Due to the fact that the spring is arranged in the valve body and sleeves the adjusting rod, the two ends of the spring are clamped between the valve body and the valve core, the elasticity of the spring can provide continuous pre-tightening force, and the valve core can tightly push the valve body during a flow stopping process, the spring is effectively prevented from loosing, a leakage accident is avoided, and the normal work of a pipeline is guaranteed.
Description
Technical field
The present invention relates to pipe fittings technical field, especially a kind of locking valve.
Background technique
Valve is standard piece conventional during pipe fitting connects, and controls the circulation of two or many pipelines, plays the effect of damming with water conservancy diversion, and existing valve mechanism is simple, and Long-Time Service back valve core easily loosens, and causes the leakage of liquid in pipeline.
Summary of the invention
Easily loosening to overcome existing valve, causing the deficiency of leakage, the invention provides a kind of locking valve.
The technical solution adopted for the present invention to solve the technical problems is: a kind of locking valve, comprises valve body, spool and adjustable lever, and spool is arranged in valve body, adjustable lever is connected on spool, be provided with spring in valve body, spring housing is on adjustable lever, and two ends are stuck between valve body and spool.
The invention has the beneficial effects as follows, in valve body, spring is set, spring housing is on adjustable lever, two ends are stuck between valve body and spool, the elastic force of spring can provide lasting pretightening force, spool can be forced to hold out against valve body closely, effectively preventing from loosening when damming, stop the generation of leakage accident, ensure the normal work of pipeline.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. valve bodies, 2. spool, 3. adjustable lever, 4. spring in figure.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of locking valve, comprises valve body 1, spool 2 and adjustable lever 3, spool 2 is arranged in valve body 1, and adjustable lever 3 is connected on spool 2, is provided with spring 4 in valve body 1, spring 4 is enclosed within adjustable lever 3, and two ends are stuck between valve body 1 and spool 2.
Spring 4 is set in valve body 1, spring 4 is enclosed within adjustable lever 3, two ends be stuck in valve body 1 and spool 2 between, the elastic force of spring 4 can provide lasting pretightening force, spool 2 can be forced valve body 1 is held out against closely when damming, effectively prevent from loosening, stopped the generation of leakage accident, ensure the normal work of pipeline.
