Abstract

The invention discloses an anti-rotary type safety valve. A valve port is formed in the bottom of a valve body; a steam exhaust port is formed in the side wall of the valve body; a valve rod with a spring is arranged in the valve body; a valve element at the bottom of the valve rod is abutted to the valve port; first chutes are formed in the two sides of the valve element; limiting sliding blocks suitable for the corresponding first chutes are formed in an inner cavity of the valve body; a sliding rod is arranged at the top end of the valve rod; the interior of the sliding rod is of a cavity structure; second chutes are formed in the inner side wall of the sliding rod; the top end of the valve rod is arranged in the cavity of the sliding rod and is also provided with a protrusion part; and the protrusion part is clamped in the second chutes separately. The anti-rotary type safety valve is stable in structure, high in safety and long in service life and can effectively prevent the valve element and the valve rod from rotating.

Description

technical field [0001] The invention belongs to the field of boiler safety control, and in particular relates to an anti-rotation safety valve. 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, easy rotation and displacement of the valve core, short service life, and manual maintenance Convenience, when the operator performs other related operations, it is easy to cause problems such as accidental touch. Contents of the invention [0003] In view of this, the present inventio...
