Abstract
The utility model relates to a right-angle check valve comprising a valve body and a valve cover, wherein an inlet and an outlet are arranged in the valve body, the valve cover is connected with the valve body and arranged at the upper end of the valve body, a guide sleeve is arranged on the lower portion of the valve cover, the valve disc is arranged at the lower end of the guide sleeve, the valve disc is sleeved on a guide rod of the guide sleeve and can move up and down along the guide rod, a baffle is arranged between the inlet and the outlet of the valve body, a through hole is arranged in the baffle, and the top end of the valve disc and the baffle can be connected in a contact mode so that the through hole is sealed. The upper end of the guide sleeve is provided with a ring-shaped edge arranged between the valve cover and the upper end face of the valve body, and a sealing ring is also arranged between the ring-shaped edge and the upper end face of the valve body. Compared with the prior art, the valve body, the valve cover, the guide sleeve and the valve disc are made from bronze and high in strength. The guide sleeve and the valve disc can move flexibly and are wear-resistant. The valve disc and the valve body are in good sealing connection. The right-angle check valve is compact in structure, good in sealing property, and long in service life.
Description
Technical field
The utility model relates to valve, the angle check valve of especially a kind of novel structure, good seal.
Background technique
At present, existing safety check generally is flat stifled formula structure, and the material of safety check mainly is cast iron.There are the shortcomings such as the valve volume is large, intensity is not high, poorly sealed, not wear-resistant, easy to leak, and working life is short usually in existing safety check.
The model utility content
The purpose of this utility model provides a kind of compact structure, good seal, the angle check valve that working life is long.
The purpose of this utility model is achieved by the following technical solution:
Angle check valve comprises valve body and valve gap, and valve body is provided with import and outlet, valve gap is connected with valve body, and described valve gap is located at valve body upper end, is provided with guide sleeve below the valve gap, the guide sleeve lower end is provided with valve disc, and valve disc is set on the guide rod of guide sleeve and can moves up and down along guide rod; Be provided with dividing plate between the import of described valve body and the outlet, have through hole on the dividing plate, described valve disc top and dividing plate can form contact and be connected and described through hole is sealed.
As optimal technical scheme of the present utility model, the upper end of described guide sleeve is provided with annular edge, and annular edge is located between the upper-end surface of described valve gap and valve body.
As optimal technical scheme of the present utility model, also be provided with seal ring between the upper-end surface of described annular edge and valve body.
As optimal technical scheme of the present utility model, the axis of described valve body import is perpendicular to the axis of valve outlet.
As optimal technical scheme of the present utility model, described valve body, valve gap, guide sleeve and valve disc all are to be processed into by bronze.
The beneficial effects of the utility model are: with respect to prior art, the utility model valve body, valve gap, guide sleeve and valve disc all are to be processed into by bronze, and intensity is higher, move flexibly between guide sleeve and the valve disc, and more wear-resistant; Can form good being tightly connected between valve disc and the valve body.The utility model compact structure, good seal, long service life.
