Embodiment example 1

[0026] Implementation Case 1: A compensating high-seal valve, including a valve stem 1, a valve cover 2, and a valve body 5. The valve stem 1 is set in the valve body 5 and passes through the inner hole of the valve cover 2. The valve cover 2 and the valve body 5 is connected by flange, and also includes packing gland 6, stainless steel packing retaining ring, stainless steel coil spring 3 and conical seal 4, one end of packing gland 6 is connected with valve cover 2, and the other end is connected with stainless steel coil spring 3, stainless steel A stuffing retaining ring 7 is arranged between the coil spring 3 and the conical seal 4, and the coil spring 3 is in a compressed state. Wherein the conical seal 4 has a layered structure and is composed of five conical rings, the diameter of the bottom of the upper conical ring is the same as the diameter of the top of the next conical ring. Wherein, the conical sealing ring has an opening structure, and the opening divides the c...

Abstract

The invention discloses a compensating type high-sealing valve which comprises a valve rod, a valve deck and a valve body. The valve rod is arranged in the valve body and passes through an inner hole of the valve deck. The valve deck is connected with the valve body. The compensating type high-sealing valve further comprises a packing gland, an elastic element and a sealing part. The end portion of the packing gland is connected with the valve deck, and the other end of the packing gland is connected with the end portion of the elastic element. The other end of the elastic element is connected with the sealing part. The sealing part is arranged between the valve rod and the valve body. The compensating type high-sealing valve has the beneficial effects of being high in abrasion resistance and corrosion-preventing performance, abrasion between the valve rod and the sealing part can be compensated automatically, the life of the sealing part is prolonged, and sealing performance is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a compensation type high sealing valve. Background technique [0002] The valve is an important control pipeline component. Its main function is to adjust the opening and closing, flow rate, flow direction, pressure, etc. of the fluid in the pipeline. As a key part of the entire device and system, especially in the petroleum and chemical industries, once the valve fails or the medium leaks, it may cause catastrophic events such as highly toxic release and explosion, which will cause major economic losses and casualties. Therefore, for valves, it is very important to choose the appropriate sealing material and sealing structure. [0003] In valve sealing, the seal between the valve stem and the valve body greatly affects the overall sealing effect of the valve. The seal between the valve stem and the valve body is generally made of annular elastic sealing material (such as rubber...
