Problems solved by technology
[0004] The anti-explosion valve used in this technical solution can discharge the flammable gas in the intake pipe from the exhaust hole on the casing in the event of flashback, effectively protecting the intake pipe, air filter and center of the engine. However, in this scheme, when the explosion-proof valve is exhausted, the spool is subjected to bending moment, which leads to serious wear of the spool; the gas in the intake pipe is not exhausted enough

Embodiment approach
[0038] As an embodiment of the present invention, the chute 41 is a rectangular slot, and a swing block 42 is installed in the chute 41 through a rotating shaft; Two sets of springs are arranged symmetrically between the arc surface and the chute 41, and the swing block 42 is driven by the main shaft 4 to move, so that the arc surface of the swing block 42 squeezes the swing rod 22; when in use, the high-pressure gas pushes the valve core 3 to move, and the valve core 3 Drive the main shaft 4 to move, the main shaft 4 drives the swing block 42 to move, the two arc surfaces at one end of the swing block 42 squeeze the other end of the swing rod 22, when the pressure of the swing rod 22 on the two arc surfaces is different, the swing The block 42 automatically adjusts the swing angle around the rotating shaft to ensure that the eccentric moment on the two arc surfaces will not act on the main shaft 4 .

The invention belongs to the technical field of engines, and particularly relates to a method for improving the self-protection ability of an engine. An explosion-proof valve used in the method comprises a conical sleeve, an exhaust pipe, swinging sheets, a sliding bearing, a spring and a clamp spring. The conical sleeve is fixedly connected into a cylindrical hole in the end face of a valve element. A conical groove is formed in the center of the conical sleeve. The exhaust pipe is slidably mounted in a center hole of the sliding bearing. A set of swinging sheets is arranged at one end of theexhaust pipe. The middles of the swinging sheets are hinged to one end of the exhaust pipe, and torsional springs are arranged at the hinged positions. Circular-arc-shaped protrusions are arranged atone ends of the swinging sheets, and a cone is formed by the set of swinging sheets in a surrounded mode. According to the method, the swinging sheets at the end of the exhaust pipe penetrate throughthe conical sleeve, the conical groove face on the conical sleeve extrudes the circular-arc-shaped protrusions on the swinging sheets, the swinging sheets swing, the conical groove of the conical sleeve deforms and is expanded, thus high-pressure gas is exhausted through the exhaust pipe, and finally the valve is opened while the explosion-proof valve resists the fierce explosion pressure.
Description
technical field [0001] The invention belongs to the technical field of engines, in particular to a method for improving the self-protection ability of engines. Background technique [0002] At present, commonly used engines, especially pneumatic engines, use premixed intake air during use, so the intake pipe is filled with flammable gas. If backfire occurs, the combustible gas in the intake pipe will burn violently and cause The pressure rises sharply, resulting in damage to the intake pipe, even the air filter and intercooler, or even more serious accidents. [0003] In the prior art, there are also some technical solutions for explosion-proof valves for engines. For example, a Chinese patent with the application number 201310019357.X discloses a method for improving the self-protection ability of the engine. The end of the housing away from the base is provided with an air vent, the housing is provided with a main shaft, the end of the main shaft close to the base is prov...
