Description

Flow control valve with non-return control function

Technical Field

The utility model relates to the technical field of valves, in particular to a flow control valve with a non-return control function.

Background

A flow control valve is a valve for controlling the amount of fluid flow, which controls the amount of fluid flow by the amount of opening of a valve flap. However, none of the conventional flow control valves has a function of preventing the backflow of the fluid.

SUMMERY OF THE UTILITY MODEL

In view of the problems identified in the background art, the present invention provides a flow control valve having a check control function.

The technical scheme of the utility model is realized as follows:

the utility model provides a flow control valve with non return control function, includes the valve body, the valve body about both ends be the opening setting, the left end of valve body is equipped with first disk seat and second disk seat from a left side to the right side in proper order, first disk seat and the coaxial setting of second disk seat are equipped with in the valve body and correspond sealed complex first valve clack and second valve clack with first disk seat and second disk seat respectively, the right-hand member of valve body be equipped with the valve rod, valve rod and second valve clack fixed connection, the second valve clack on be equipped with the ejector pin that stretches out left, first valve clack on be equipped with the guide bar that stretches out left, the valve body in be equipped with guide bar sliding fit's uide bushing, the lateral wall of valve body on be equipped with out the liquid hole.

The utility model is further provided that the first valve seat and the second valve seat are arranged at intervals from left to right.

The utility model is further provided that the ejector rod, the guide rod and the first valve seat are coaxially arranged.

The utility model is further arranged in that the left end of the valve body is connected with a liquid inlet pipe, and a liquid outlet pipe is connected with the liquid outlet hole.

The utility model is further provided that a convex contact part is arranged on the right side of the first valve clack, and the contact part is arranged corresponding to the ejector rod.

By adopting the technical scheme, the utility model has the beneficial effects that:

the flow control valve with the non-return control function provided by the utility model has the advantages that the movement of the second valve clack is controlled by the valve rod, the movement of the first valve clack is controlled by fluid after the second valve clack is opened, and particularly, when liquid backflow occurs, the backflow liquid pushes the first valve clack to move leftwards to form sealing fit with the first valve seat so as to close the liquid inlet of the valve body.
