Novel breather valve

Abstract

The invention discloses a novel breather valve. The novel breather valve comprises a cylinder body, a hollow lower end cover, a sealing piece and a ball body. The sealing piece is located between thecylinder body and the lower end cover, a baffle is arranged in a steam outlet of the cylinder body, an internal thread is arranged on the inner wall of the cylinder body, and a circular hole is formedin the center position of the baffle. The lower end cover is provided with a end head for entering of steam, a threaded head for penetrating of the steam and at least two limiting vertical plates, the limiting vertical plates are uniformly and separately arranged on an end opening of the top end of the threaded head, the tail end of the threaded head is connected with the end head, and at least two circular arc grooves are uniformly formed downwards in the top end of the inner hole wall of the threaded head. The ball body is placed at the end opening position of the top end of the threaded head and carries out limiting on the threaded head through the limiting vertical plates, the baffle is located above the limiting vertical plates, the circular arc grooves enable a gap to be formed between the ball body and the inner hole wall of the threaded head, and the diameter of the ball body is greater than that of a circular hole and an inner hole of the threaded head. According to the novelbreather valve, the ball body is used for sealing, and the sealing performance is good; and the sealing piece is convenient to disassembly and assembly, and the replacement cost of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of breathing valves, in particular to a novel breathing valve which is easy to assemble and disassemble and prolongs the service life. Background technique [0002] The original breathing valve is spring-type, and it works in the environment of high temperature, high pressure and corrosive smoke for a long time. This harsh environment will reduce the service life of the breathing valve; on the one hand, some corrosive smoke washes and corrodes the sealing surface of the breathing valve On the other hand, the spring of the breathing valve will be corroded, causing the sealing of the breathing valve to be loose, resulting in steam leakage, increasing the boiler supply water, and when people are close to the steam valve, it is easy to cause burns when blowing soot suddenly; at the end of soot blowing As the remaining part of the steam in the casing condenses into water and flows back from the breathing valve, i...
