Problems solved by technology

[0004] When the liquid level rises, the floating ball rises and directly collides with the connecting pipe. In the system application, the floating ball control valve needs to be opened and closed frequently. Since the floating ball and the connecting pipe are thin-walled parts, frequent collisions between the two are easy Cause the floating ball or connecting pipe to deform or even wear and tear

Abstract

The invention relates to a ball float control valve, which includes a connecting pipe, a valve seat, a valve needle, a floating ball and a connecting part; The hole fits and forms a seal, which is used to open and close the inner hole of the valve seat; the connecting part is pivotally connected to the valve seat through the first rotating shaft, one end of which is fixedly connected with the floating ball, and the other end is connected with the valve needle, and the floating ball can float with the liquid surface. The connecting part drives the valve needle to move to open and close the inner hole of the valve seat; there is also an abutment part fixed or integrally formed in one of the connecting part and the valve seat, when the connecting part and the valve seat are abutted by the abutting part When connecting, the inner hole of the valve seat is open, and there is a gap between the floating ball and the connecting pipe. The float control valve can effectively improve the durability of the frequently opened and closed float control valve and prolong its service life.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a float control valve. Background technique [0002] The float control valve is a liquid level control device, which has the function of opening and closing the pipeline to mechanically control the liquid level. It does not need to provide power and has no complicated circuits. The oil separator container in the float valve refrigeration system is more commonly used. The main structure is composed of a float ball, a connecting pipe, a valve seat, a valve needle, a rotating shaft, and a connecting part. [0003] Working principle: The floating ball is always suspended on the liquid surface. When the liquid level rises, the floating ball rises, and the connecting part drives the valve needle to move down. At this time, the valve seat hole is opened and the pipeline is opened; when the liquid level drops, the floating ball The ball sinks, and the valve needle is still moved up by th...
