Abstract

The utility model relates to a flushing valve, more specifically a new float bowl valve core for flushing valves. The utility model relates to a valve body and a sealing ring which is sheathed with the valve body, wherein the lower part of the valve body is provided with an annular groove of which the inner part casts a sealing washer, and the sealing washer and the valve body are stuck into a whole body. Compared with original float bowl bodies, the improved integral float bowl body has the advantages that the integral type sealing water stopping washer is directly cast on the float bowl body, the water stopping washer and the float bowl body are tightly combined together for preventing the defect of the looseness of original circular nuts, the utility model avoids the loss of water stopping function caused by the dropping of the water stopping washer caused by the looseness of circular nuts and enhances service life, the sealing water stopping washer is directly cast on the float bowl body saving a circular nut, and the utility model saves material and processing expenses, reduces cost and enhances economic benefit.

Description

A kind of novel flushing valve floating drum spool

Technical field:

The utility model relates to a kind of flushing valve, is specifically related to a kind of novel flushing valve floating drum spool.

Technical background:

The floating drum body rubber sealing packing ring of various sanitary wares all is a separate type on the existing market, must lock with round nut during assembling, threads engage is adopted in round nut and floating drum body lower end, round nut rubber sealing packing ring locking floating drum body lower end, become end face seal with the water level mouth, but nut is loosening easily in use for some time, severe patient even come off, influence sealing effectiveness, cause sealing out of control.

Summary of the invention:

The purpose of this utility model provides a kind of novel flushing valve floating drum spool.

A kind of novel flushing valve floating drum spool comprises valve body, is sheathed on the sealing ring on valve body top, and valve body lower portion is provided with annular groove, is cast with seal washer in the annular groove, and seal washer and valve body stick into an integral body.

For the reinforced seal effect, the joint ring outside also is cast with seal washer, sticks into an integral body with seal washer, joint ring, valve body in the annular groove.

Improve the whole floating drum body in back and original floating drum body relatively, have these points advantage: the direct pouring of integral seal sealing packing ring is on the floating drum body, sealing packing ring and floating drum body strong bonded are together, can prevent the defective that original round nut is loosening, more needn't worry round nut to get loose and cause the sealing packing ring to come off and lose the worry of sealing effect, improve application life; The direct pouring of hermetic seal packing ring on the floating drum body, can be saved a round nut, save material and processing charges, reduce cost, increase economic efficiency.
