The valve core sleeve in the traditional quick-opening valve core is of an integrated structure, the machining requirement is high, and meanwhile, the machining cost is high.

At present, the machining of the quick-opening valve core in the market is mostly integrated machining, and the machining is almost not divided, because the more accessories are, the qualification rate can be reduced definitely, and the more machining steps are generally. For example, Chinese patent discloses a valve core sleeve in a quick-opening valve core and a processing method thereof (publication number: CN 103711934A), although a groove drawing process is cancelled, the maximum thickness of the wall thickness of a limit boss is kept, and the problem that a cylinder body at the limit boss is easy to generate dark cracks to cause rework in the traditional process is well solved; however, the valve core is integrally machined, which is difficult to machine.

Therefore, how to provide a quick-opening valve core which is convenient to process, reduces the cost and can improve the yield and the product precision is a problem that needs to be solved urgently by technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a quick-open valve core.

A quick-opening valve cartridge comprising: comprises a valve core main body and a positioning disc, wherein the upper part of the valve core main body is provided with a through valve rod hole, and the middle part of the outer wall of the valve core main body is provided with a through water inlet hole;

the positioning disc is clamped in the valve core main body; two sections of corresponding positioning blocks are arranged on the inner wall of the positioning block;

the inner groove wall of the valve core main body is provided with a limit groove matched with the positioning disc, and the positioning disc is clamped in the valve core main body through the limit groove.

Preferably, the limiting groove is a circular groove and is arranged under the valve rod hole tightly attached to the valve core main body.

The beneficial effects of the scheme are as follows: the inner wall of the valve core main body is provided with the circular groove, and the positioning disc is expanded into the circular groove of the valve core main body through the die, so that the positioning disc is not easy to slip off.

Preferably, a second limit groove is formed in the groove wall of the inner portion of the valve core main body.

Preferably, the number of the second limit grooves is two, and the two second limit grooves are symmetrically arranged with respect to the center of the valve core main body.

Preferably, the outer wall of the positioning plate is provided with two clamping blocks matched with the second limiting groove.

The beneficial effect of above-mentioned scheme is: not only the phenomenon of rotation in the valve core main body when the positioning disc edge is pushed into the top of the inner wall of the valve core main body is prevented; but also can fix the still of the ceramic water valve plate to prevent the still from rotating.

Preferably, the valve core main body is manufactured by machining a raw material by cold heading to obtain a valve core main body blank and then machining the valve core main body blank.

Preferably, the positioning disc is manufactured by a stamping process.

Preferably, the positioning disc enters the valve core main body through the stamping action of a die and falls into the circular groove.

The utility model discloses for prior art gain following technological effect:

the utility model discloses with the positioning disk joint in the case main part that opens soon, separate the two, make with different processing technology respectively, not only solved and can not accomplish simultaneously to the problem of dashing the groove and dashing the positioning disk technology, but also for subsequent machining maximum reduction the processing cost, better promotion product percent of pass and product precision.
