Description
Technical Field
The utility model relates to a valve field has especially related to an air-vent valve with disk seat clearance function.
Background
A pressure regulating valve is a valve for regulating water flow or gas pressure, and is characterized by comprising a compact pressure reducing valve, a medium flow pressure reducing valve, a conventional high-pressure reducing valve, a secondary pressure reducing valve and a low-pressure large flow valve according to the using characteristics, but when the water flow pressure regulating valve is used for a long time, scales are accumulated at an internal water outlet, so that the water outlet difficulty and the water pressure regulation are deviated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide an air-vent valve with disk seat clearance function.
In order to achieve the above object, the technical solution of the present invention is:
the pressure regulating valve with the valve seat cleaning function comprises an indicating rod, a valve body below the indicating rod and a membrane assembly at the lower end of the valve body, wherein a water inlet is formed in the left end of the valve body, a water outlet is formed in the right end of the valve body, a water outlet valve seat is arranged inside the valve body, a valve core is arranged inside the water outlet valve seat, a cleaning brush is arranged on the outer side surface of the valve core, and a limiting sleeve is arranged at the upper end of the.
Preferably, the surface of the cleaning brush is attached to the inner side of the water outlet valve seat.
Preferably, the inner side surface of the cleaning brush is provided with a lug which is clamped into a guide rail of the valve core.
Preferably, the surface of the limiting sleeve is provided with semicircular threads, and the inner side of the top of the cleaning brush is provided with a semicircular bulge which is embedded into the threads of the limiting sleeve.
Through adopting foretell technical scheme, the beneficial effects of the utility model are that:
because the cleaning brush is arranged on the side surface of the valve core in the pressure regulating valve, when the valve core is lifted or opened, the cleaning brush rotates to scrub scale accumulated on the inner side of the water outlet valve seat, and the water outlet difficulty and the water pressure rising caused by the fact that the scale is accumulated in the water outlet of the water outlet valve seat are prevented.
