Abstract
The utility model belongs to the field of valves, and discloses a novel stop valve which overcomes the defect that impurities exist in a valve cavity of an existing stop valve and can not be removed. The novel stop valve comprises a valve body and a valve core, an inlet and an outlet are arranged on the valve body, a valve core port is formed in the top of the valve body, the inlet, the outlet and the valve core port are communicated with an inner cavity of the valve body respectively, internal threads are arranged on the inner wall of the valve core port, external threads matched with the internal threads are arranged on the valve core, and an internal hexagonal hole is formed in the top end of the valve core. Vertical movement of the valve core can be achieved by adjusting through an internal hexagonal wrench, a filter unit is arranged in the inner cavity of the valve body and fixed through a fixing block, and the filter unit is located below the valve core. According to the novel stop valve, the filter unit is additionally arranged in the inner cavity of the valve body, therefore, the impurities passing through the inner cavity of the valve body can be filtered, work efficiency of the stop valve is improved, and the usage range is enlarged.
Description
Technical field
The utility model belongs to valve field, especially relevant with a kind of stop valve.
Background technology
Stop valve is the critical component that is arranged at indoor apparatus of air conditioner and off-premises station.Stop valve comprises valve body and spool, valve body is provided with entrance, outlet and spool mouth, entrance, outlet and spool mouth and body cavity connect, spool mouth inwall is provided with internal thread, spool is provided with the external screw thread with spool mouth screw-internal thread fit, and the spool top is provided with inner hexagonal hole, the adjusting of through hole inner hexagon spanner, realize the movement of spool, thereby realize spool by the conducting between indoor interface and outlet and close.Because the medium by the stop valve inner chamber contains impurity unavoidably, can affect the normal operation of stop valve and next working link thereof.
The utility model content
The purpose of this utility model is intended to overcome in existing stop valve valve pocket the defect that has impurity and can't remove, and a kind of novel cutoff valve with removal of contamination function is provided.
For this reason, the utility model is by the following technical solutions: a kind of novel cutoff valve, comprise valve body and spool, valve body is provided with entrance and exit, the top of valve body is provided with the spool mouth, entrance, outlet and spool mouth connect with body cavity respectively, spool mouth inwall is provided with internal thread, spool is provided with the external screw thread with screw-internal thread fit, the spool top is provided with inner hexagonal hole, adjusting by inner hexagon spanner, realize moving up and down of spool, it is characterized in that, be provided with filter in described body cavity, filter is fixed on the body cavity wall by fixed block, filter is positioned at the below of spool.
As to technique scheme supplement and perfect, the utility model also comprises following technical characterictic.
Described spool comprises valve rod and valve block, and valve block is installed on the lower end of valve rod, and the transverse width of valve block is greater than the transverse width of valve rod.
Be provided with sealing ring on described valve block outer peripheral face, when the spool that prevents stop valve is closed, medium flows into.
Described stop valve also comprises block, mounts cover the top in valve body.
Use the utility model can reach following beneficial effect: the utility model is by body cavity, setting up filter, thereby can filter the impurity passed through in body cavity, improved operating efficiency and the use of stop valve.
