Press type safety valve with good stabilization effect

Abstract

The invention relates to the technical field of safety valves and discloses a press type safety valve with a good stabilization effect. The press type safety valve comprises a valve body, the top of the valve body is fixedly provided with a valve cover, the top of the valve cover is movably provided with a moving rod running through the top of the valve cover and extending into the valve cover, the top of the moving rod is fixedly connected with a press button, and the left side and the right side of the moving rod are both fixedly connected with moving bins located inside the valve cover. According to the press type safety valve with the good stabilization effect, by means of the arrangements of horizontal springs and position-limiting rods, the position-limiting rods are made to be capable of moving horizontally left and right; by means of the manners that the left side of the left position-limiting rod is arranged in an inverted isosceles trapezoid, the right side of the left position-limiting rod is arranged in a horizontal T shape, and clamping blocks are provided eight and each clamping block is a horizontal right triangle, when the moving rod moves downwards through pressingof the press button, the clamping blocks clamp the position-limiting rods at the pressed positions, and pressure adjustment of a vertical spring is realized; and by means of the this structure, threaded connection is avoided, and the whole safety valve is made to be more stable.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a pressure-type safety valve with good stabilization effect. Background technique [0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. , The safety valve belongs to the automatic valve category, mainly used in boilers, pressure vessels and pipelines, the control pressure does not exceed the specified value, and plays an important role in protecting personal safety and equipment operation. Note that the safety valve must pass a pressure test before it can be used. [0003] Spring-type safety valve refers to relying on the elastic pressure of the spring ...
