Plug values are indispensiblefor connecting the high-pressure manifold during cementing and fracturing operations in oil fields. They are also used for similar high-pressure fluid control operations. Up to now,this product is ideal for use in cementing and fracturing manifoldsbecause of its good features such as compact structure,small torque ,easy maintenance,quick opening action and labor-saving,ect.
Operating principle and structural charavteristics：
■the plug value is mainly made up of the body,the hand wheel,thepluger and the others.
■the 1502 union connetion is applied to connect its inlet and outlet to he pipeline (this can be custom-made according to different requirements) .the precise fit between the value body and the liner is insured by means of cylindrical fitting, and the sealant is inlaid through the outer cylindrical surface of the liner to make sure that it is hermitically sealed.
■the cylindrical meal-to-meal fit between the liner and the pluger is adopted to insure a high fiiting accuracy and thereby reliable sealing performance.
■note：even under a pressure of 15000psi,the value can be opened or closed with ease. |
