Abstract

The invention relates to the technical field of pipeline accessories, in particular to a sealing valve, which 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 onto the valve core; a sealing hole is formed in the valve body, is a counter bored hole, and is located on the inner wall of the valve body and right below the valve core. The sealing hole is formed in the inner wall of the valve body, is the counter bored hole, and is located right below the valve core; the valve core is dropped down during interception, the bottom part of the valve core is embedded in the sealing hole to form a plug structure, and the fluid is thoroughly intercepted, so that the sealability is greatly improved, the occurrence of leakage accidents is avoided, and the normal work of pipelines is ensured.

Description

Sealed valve
Technical field
The present invention relates to pipe fittings technical field, especially a kind of sealed 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, existing valve mechanism is simple, gap between Long-Time Service back valve core and valve body is increasing, and sealing reduces, and causes the leakage of liquid in pipeline.
Summary of the invention
Easily failing to overcome existing valve seal performance, causing the deficiency of leakage, the invention provides a kind of sealed valve.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sealed valve, comprises valve body, spool and adjustable lever, and spool is arranged in valve body, adjustable lever is connected on spool, is provided with closed hole in valve body, and closed hole is a counterbore, be positioned on valve interior wall, position immediately below spool.
The invention has the beneficial effects as follows, valve interior wall arranges closed hole, and closed hole is a counterbore, is positioned at position immediately below spool, when damming, spool declines, and bottom is embedded in closed hole, forms plug-like structure, thoroughly block fluid, substantially increase sealing, stopped 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. closed hole in figure.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of sealed 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 closed hole 4 in valve body 1, closed hole 4 is a counterbore, is positioned on valve body 1 inwall, position immediately below spool 2.
Valve body 1 inwall arranges closed hole 4, closed hole 4 is a counterbore, be positioned at position immediately below spool 2, when damming, spool 2 declines, bottom is embedded in closed hole 4, form plug-like structure, thoroughly block fluid, substantially increase sealing, stop the generation of leakage accident, ensure the normal work of pipeline.
