Problems solved by technology

However, since the outer flame retardant and the inner flame retardant in the explosion-proof valve are composed of several circular flame retardant pieces alternately placed on the front and back and stacked layer by layer, the processing flow of the explosion-proof valve becomes complicated and the production efficiency is reduced. , and it is also not conducive to the replacement of internal and external flame retardants in the later period

Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, when the crankcase explosion-proof valve explodes inside the crankcase to generate high-pressure airflow and high-temperature flame and release them, the pressure is weakened and the flame is extinguished in the explosion-proof valve. The crankcase explosion-proof valve is composed of a panel 1, a seat plate 2, an inner flame retardant block 3, an outer flame retardant block 4, a valve plate 5, and a spring 6 and the like.

[0024] Wherein, the seat plate 2 is in the shape of a ring, and the explosion-proof valve is connected to the crankcase through the seat plate 2, and the seat plate 2 is fixedly connected with a panel 1 parallel to it, and the panel 1 is disc-shaped. The inner flame retardant block 3, the outer flame retardant block 4, the valve plate 5 and the spring 6 are all located between the seat plate 2 and the panel 1, wherein a valve cavity 7 is formed between the inner flame retardant block 3, the panel 1 and the s...

Abstract

The invention provides a crankcase anti-explosion valve, and belongs to the technical field of machines. The crankcase anti-explosion valve solves the problem that the assembling process of an existing anti-explosion valve is complex. An elastic earpiece with an improved structure comprises an annular base plate and a face plate fixedly connected with the base plate, the base plate is parallel to the face plate, a valve plate and a spring are fixed between the base plate and the face plate, an inner antiflaming block and an outer antiflaming block are further fixed between the base plate and the face plate, the inner antiflaming block and the outer antiflaming block are annular, and the inner antiflaming block is sleeved with the outer antiflaming block. The crankcase anti-explosion valve has the advantages that production efficiency is high, and the inner antiflaming block and the outer antiflaming block are convenient to replace.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an explosion-proof valve, in particular to a crankcase explosion-proof valve. Background technique [0002] At present, the movement of the crankshaft in the crankcase of an internal combustion engine will cause the oil mist in the crankcase to detonate, thereby generating high-pressure airflow and high-temperature flames. The explosion-proof valve is installed on the crankcase to release the pressure of the crankcase. While depressurizing, it prevents the passage of flame and then closes to prevent air from entering. At present, common explosion-proof valves generally cannot completely extinguish the flame in the explosion-proof valve, and the effect of weakening the high-pressure airflow produced by the explosion is not ideal. [0003] In order to solve this problem, the applicant once provided an explosion-proof valve [application number: 200810061321.7; authorized announcemen...
