AI Technical Summary

Benefits of technology

The present invention provides a ball valve with an actuator that prevents danger and loss during operation. The actuator has a connection portion with a round groove and a C-shaped buckle that secures the actuator to the ball through buckling, preventing the actuator from blowing out by the pressure of the valve during damage or maintenance. Overall, this design ensures safe and reliable operation of the ball valve.

Problems solved by technology

However, the actuator is easily blowing out from the valve body by the pressure of the fluid inside the valve during a maintenance or repair operation which is very dangerous to the operator and facility.

Abstract

A ball valve having an actuator of blow out prevention includes a valve body, actuator, and a ball. The valve body has a valve chamber inside thereof and a passageway, top bore, bottom bore extending from the valve chamber. The actuator has a connection portion penetrating through the top bore to the valve chamber, the connection portion has a round groove and a C-shaped buckle. The actuator serves to be rotated by an external driver. The ball inside the valve chamber serves to control the flow of the valve chamber. The ball has a connection hole engaging the connection portion of the actuator. The C-shaped buckle retains the actuator connected to the ball through buckling the round groove of the connection portion receiving inside the connection hole of the ball so that the actuator will not blow out by the pressure of the valve during a damage or maintenance.

Description

FIELD OF THE INVENTION[0001]The present invention relates to valve, and particular to a ball valve having an actuator of blow out prevention to prevent damage or danger.DESCRIPTION OF THE PRIOR ART[0002]Known ball valve includes a valve body having a chamber and passageway linking to the chamber, a top bore, and a bottom bore. An actuator penetrates through the top bore into the chamber to rotate a ball inside the chamber to open or close the valve. The ball is arranged to a valve seat to control the flow of the fluid passing through the valve.[0003]However, the actuator is easily blowing out from the valve body by the pressure of the fluid inside the valve during a maintenance or repair operation which is very dangerous to the operator and facility.SUMMARY OF THE PRESENT INVENTION[0004]Accordingly, the primary object of the present invention is to provide a ball valve having an actuator of blow out prevention to prevent danger and loss during operation.[0005]To achieve above object...
