Description

The valve {VALVE} having the rotary opening /

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve, and more particularly, to a valve having a rotary opening and closing member.

Generally, a valve refers to a device for controlling the flow rate of a gas or a liquid flowing through a pipe and regulating reverse flow.

In particular, check valves are connected in series between piping and piping or piping and devices (eg boilers, water tanks, etc.) to provide a back flow of feeds (eg water, oil, air, Thereby preventing a water hammer from being generated in the impeller portion of the pump due to the backward flow of the conveyed object.

For example, in a boiler system, hot water is fed in one direction, and water is used to prevent reverse flow of cold water.

Such a check valve is roughly divided into a lift type in which the check valve is linearly moved by the opening / closing water pressure and a swing type in which the check valve is rotated by the pressure of the opening / closing valve. The lift type is a plate type type and ball type.

The structure and operation of a conventional ball-incorporated check valve will now be described.

The outer surface side of the conventional circular check valve is formed with a screw groove for inserting and fixing the pipeline and the device, and a tightening groove for inserting a minus (-) driver when the check valve is fixed. And a spring for preventing a backward flow of the conveyed object by applying a predetermined elastic force to the backflow preventive ball 2.

Here, when the inflow pressure of the object to be conveyed is excessively greater than the elastic force of the spring, the spring is brought into close contact with the object. When the state is maintained for a long time or repeatedly, the resilient restoring force of the spring is weakened, The pressure was changed.

Accordingly, when the backflow phenomenon occurs, the spring can not properly support the backflow prevention ball, and the backflow may be caused.

A prior art related to the present invention is Korean Patent Laid-Open Publication No. 10-2003-0012242 (Feb.
