An adjustable safety valve for a boiler

Abstract

The invention provides a regulating type safety valve for a boiler. A slide rod with a sliding cavity and a limiting rod are arranged in an upper valve body, a valve rod is arranged in a lower valve body, the top end of the valve rod is locked in the sliding cavity in the slide rod, and a spring limiting buckle is fixedly arranged on the valve rod; a spring sleeves the valve rod, and the spring is located between the bottom plate of the upper valve body and the spring limiting buckle and leans against the bottom plate of the upper valve body and the spring limiting buckle; a valve core is further fixedly arranged at the bottom end of the valve rod; a valve port is formed in the bottom of the lower valve body, a steam exhaust port is formed in the side wall, and the valve core leans against the valve port; and the upper valve body and the lower valve body are in threaded connection. The regulating type safety valve for the boiler provided by the invention has the advantages of being simple and rapid to adjust the pressure, stable in structure and high in safety.

Description

technical field

[0001] The invention belongs to the field of boiler safety control, and in particular relates to an adjustable safety valve for a boiler. Background technique

[0002] Boiler is a common energy equipment used in industrial production. During boiler operation, it is very important to control the internal pressure of boiler. As an important component of pressure control, boiler safety valve can play an important role in protecting personal safety and equipment operation. . Common safety valves have various structures such as hammer type and spring type, which can be automatically adjusted according to the set pressure value, but the existing safety valves often have complex structures, manual maintenance and pressure adjustment are inconvenient, and when operators perform other related operations It is easy to cause problems such as accidental touch. Contents of the invention
