Technical Field

The invention belongs to the technical field of valves, and particularly relates to a high-temperature steam valve.

Background

A valve is a device used in a fluid system to control the direction, pressure, and flow of a fluid. The valve is a device that controls the flow rate of a medium in a pipe or equipment by flowing or stopping the medium. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. In the high temperature shaping plastic film course of working, need let in high temperature steam mixed medium in the shaping roller and be used for cooling off the fuse-element, but because steam mixed medium has the gas-liquid phase change, and there is dissolved oxygen in the aquatic, synthesize and can lead to cooling medium pressure shakiness, produce vibrations, and then influence pipeline seal's life-span and the rotation precision of roller.

Disclosure of Invention

The invention mainly aims to provide a high-temperature steam valve, which solves the problem that the existing gas-liquid mixed medium is unstable in pressure in a roller and generates vibration.

In order to achieve the technical effects, the invention adopts the following technical scheme:

a high-temperature steam valve is composed of a valve body, a valve cover, a valve clack, a valve core, a first step and a second step, wherein the valve core comprises a clamping part and a core head.

The valve body is provided with end faces which are tightly connected with the inlet pipeline, the outlet pipeline and the valve cover.

The hair flap and the valve core are arranged in the valve body.

The valve body is provided with a first step and a second step at the connecting end of the inlet pipe.

The first step is used for arranging a sealing ring, preferably a graphite sealing ring, and can provide a good sealing effect.

The second land is for the card and the spool.

The clamping part is a circular ring with a cross-shaped support in the middle, is connected with the core print and has the same thickness as the second step.

The core head is formed by connecting multiple layers of round tables in series, preferably 3 layers, and can block impact of gas-liquid mixed media in a layered mode and reduce vibration.

When the gas-liquid mixed medium enters, the valve clack is opened through the buffering of the valve core and enters the roller.

The invention has the beneficial effects that: (1) the invention has simple structure, low cost and easy popularization and use.

(2) The high-temperature steam valve has good sealing performance and can alleviate the vibration problem caused by the pressure fluctuation of the gas-liquid mixed medium.
