Technical Field

The invention relates to a copper ball valve convenient to open and close.

Background

The ball valve, the half ball valve and the butterfly valve are used in a fluid conveying pipeline, particularly water conveying pipelines, the ball valve, the half ball valve or the butterfly valve are respectively provided with a valve body and a copper valve core, a sealing pair is arranged between the valve body and the copper valve core, and the valve body and the copper valve core are tightly attached through the sealing pair so as to realize the sealing between the copper valve core and the valve body. However, in a low-temperature environment, residual water stains often exist between the copper valve core and the sealing pair, the residual water stains can be condensed into ice after long-term low temperature, and due to the fact that the volume of the frozen water is increased, large resistance can be caused to the rotation movement of the copper valve core, so that the normal opening and closing of the copper valve core are hindered, and the small ice crystals often have certain hardness and sharp surfaces, the surfaces of the sealing pair can be scratched, and the sealing effect of the sealing pair is affected.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a copper ball valve which is convenient to open and close.

A copper ball valve convenient to open and close comprises a valve body, a valve rod and a copper valve core; the utility model discloses a valve body, including the valve body, copper case, electrical heating screw rod, annular groove, heating rod accommodation hole, copper case, valve rod, valve body, the inside cavity of copper case be located the valve body, the top of copper case links to each other with the valve rod, the bottom of copper case links to each other with the electrical heating screw rod, the head of electrical heating screw rod stretch into the counter bore of copper case bottom, be equipped with annular groove on the upper surface of electrical heating screw rod afterbody, annular groove in be equipped with O type circle, the upper surface butt of O type circle is on the outer wall of valve body, the middle part of electrical heating screw rod is equipped with the.

Preferably, the head of the valve rod is connected with a handle seat, and the handle seat is connected with a transverse handle.

Preferably, the left end and the right end of the copper valve core are connected with the inner wall of the valve body through sealing gaskets.

Preferably, the top end of the valve body is connected with a positioning seat, the top end of the positioning seat is connected with a positioning block, the positioning block is sleeved on the valve rod, a positioning ring, a gasket and a wave spring are sequentially connected between the positioning block and the positioning seat, and the top of the valve rod is screwed with a hexagon bolt. The positioning block is tightly pressed on the positioning seat through the hexagon bolt, and the compensation is carried out through the positioning ring, the gasket and the wave spring, so that the threads cannot be loosened, and the sealing performance is ensured.

Preferably, the positioning seat is connected with the valve rod through a self-lubricating sleeve.

Has the advantages that:

thereby the condition that hinders copper ball valve normal use appears the ice crystal easily to sealed department, bottom at copper case is equipped with the electrical heating screw rod, electrical heating rod through among the electrical heating screw rod, the electrical heating screw rod is heated in proper order, copper case heats, thereby make the ice crystal attached to copper case surface melt, it is more smooth and easy to make the copper ball valve open and close, also can not scratch seal structure, and the electrical heating screw rod of bottom has still played spacing effect, prevent that copper case from taking place the skew when rotatory.
