Abstract
The utility model discloses an automatic check valve. The automatic check valve comprises a valve body, a pressing plate, a sealing pad, a valve plate, a rocking bar, a middle head spacer, and a valve cover. The valve body is a horizontal pipe structure with a large belly. An elliptical notch inclining downwards is formed from an inlet end to an internal thick cavity, and the valve plate is disposed in the notch in a sealed manner. The valve plate is an elliptical plate, and the inner surface, close to the inlet end, of the valve plate is provided with the pressing plate. The sealing pad is arranged between the pressing plate and the valve plate, and the valve plate is closely and fixedly connected with the rocking bar. The other end of the rocking bar is fixed onto the upper inner wall of the valve body and is rotatable around a fixed point. The top end of the belly part of the valve body is provided with a mounting port and equipped with the valve cover. The middle head spacer is arranged between the valve cover and the valve body. The automatic check valve is simple in structure and convenient to operate. The automatic check valve can allow and stop the flowing of fluid automatically without needing manual operation. Moreover, the automatic check valve has good check effect and good practicality.
Description
Technical field
The utility model relates to valve technology field, especially a kind of automatic check valve.
Background technique
In existing engineering, there are many occasions will use valve, especially, in chemical industry, hydraulic engineering, need valve as the mobile keying element of fluid.In some engineering, need to guarantee that fluid flows along fixing direction, prevent that fluid from flowing backwards, technician has designed the safety check of one-way conduction for this reason, and fluid flows along the direction designing in advance, if reverse flow, can cause valve closing, stop and reflux.
Model utility content
The utility model provides a kind of automatic check valve, automatically completes conducting and the fluid stopping operation of fluid without External Force Acting.
The technical solution of the utility model:
A kind of automatic check valve, include valve body, pressing plate, sealing gasket, valve plate, rocking bar, middle head gasket, valve gap, described valve body is the flat sleeping pipe structure that tripe is large, entrance point to place, inner thick chamber is the elliptical incision under oblique, incision sealing is mounted with valve plate, described valve plate is oval plate, valve plate is provided with pressing plate by entrance point internal surface, between pressing plate and valve plate, be lined with sealing gasket, valve plate is close to and is fixedly connected with rocking bar, the described rocking bar the other end is fixed on the upper inwall of valve body, can rotate around immovable point, valve body tripe portion top is provided with mount inlet and valve gap is installed, between valve gap and valve body, be lined with middle head gasket.
Advantage of the present utility model:
The utility model apparatus structure is simple, easy to operate, automatically completes conducting and the fluid stopping operation of fluid, and without manual operation, and non-return effect is good, and practicability is good.
