How much do you know about the new gate valve? The Low price socket end gate valve editor will take you to a brief understanding.
The structure of the new gate valve includes a valve stem and a transmission orifice plate. The end of the valve stem is provided with an external thread, and the inner side of the external thread is provided with an annular step. In the screw hole on the wedge block, a retaining spring is set between the outer side of the step and the transmission orifice plate, and a nut presses the step to fix the valve stem and the transmission orifice plate; the cross section of the oblique wedge block is an isosceles trapezoid, and the screw The hole is located in the center of the bottom surface; on both sides of the oblique wedge, there are valve cores consisting of two identical square valve plates, the cross-section of the valve plates is a right-angled trapezoid, and the oblique angle of the right-angled trapezoid is equal to that of the isosceles trapezoid. , the hypotenuse of the right-angled trapezoid and the hypotenuse of the isosceles trapezoid are reversely attached, the parallel sealing surfaces on both sides of the valve core are in contact with the sealing surface of the valve seat, and the friction angle between the parallel sealing surface and the sealing surface of the valve seat is smaller than that of the isosceles trapezoid. The four corners of the spool are respectively provided with resilient elastic mechanisms. The new gate valve has the advantages of wide application range and long service life.
The above is what the editor of Low price socket end gate valve tells: a brief introduction to the knowledge of the new gate valve.
