High level liquid control device

Abstract

The invention relates to a high-level liquid control device, which is characterized in that the valve body is made of plastic, the lower end is a water inlet of an internal thread, the outer end is a hexagonal screw head, the side of the lower end has an oblate hole with the same width as the valve body, and the upper and lower ends It is a semicircle with edges around it, and there is a groove along the surface. There are symmetrically distributed screw holes corresponding to the blind plate on the inner side of the groove. There is a 60° positive tapered sealing port on the inner upper side. Line and the center line of the valve body are on the same straight line, there is a flat protrusion with a hole in the middle of the upper end of the oblate hole, the outer arm of the oblate hole has a round boss, and there is a threaded protrusion in the middle The cylindrical countersunk through hole has a blind hole on the inner wall of the opposite side. The beneficial effect of the present invention is that the present invention is widely used, has a good water control effect, can save a lot of manpower and material resources, has a long service life, and is not easily damaged. Maintenance is simple.

Description

technical field [0001] The invention relates to solar energy appliances, roof expansion water tank appliances, water tower appliances, high-level oil tank appliances for industrial fans, in particular to a high-level liquid control device. Background technique [0002] This kind of high-level liquid control device on the market is an electric control valve. The power line is outside and is often maintained. Water flows out from the overflow pipe at the top, and the valve must be closed again. There are many overflow pipes in one building, which takes up a lot of space, which is a waste of manpower and material resources. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art and provides a high-level liquid control device. The technical proposal includes: a valve body, a main plate gland, an adjustment support nail, a nut, a spring, a large pad, a tapered rubber pad, and a valve body gland , valve body rubber ring, gland screw...
