Embodiment Construction

[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] As shown in Figure 1, Figure 2 and Figure 3, this explosion-proof valve is applied on the crankcase to release the high-pressure airflow and high-temperature flame generated by the explosion when the explosion occurs inside the crankcase. While releasing, the pressure is weakened and the flame is extinguished in the explosion-proof The valve then closes to prevent air from entering. The explosion-proof valve includes a panel 1, a seat plate 2, a valve port sealing plate 3, a flame retardant sheet 4, a flame retardant 5 and a flame retardant ring 6 and the like.

[0026] Specifically, the seat plate 2 is ring-shaped, and can be connected to the crankcase through the seat plate 2. The panel 1 is disc-shaped, and a fla...

Abstract

The invention provides an explosion-proof valve, belonging to the machinery technology field, which solves the problems that a current explosion-proof valve can not completely blow out flame in the explosion-proof valve, and the effect of reducing high pressure air flow in explosion is not favorable. The explosion-proof valve comprises a ring-shaped seat board, a panel which is fixed with the seat board, a plurality of ring-shaped flame-proof sheets which are fixed between the panel and the seat board. The ring-shaped flame-proof sheets form a valve cavity by superposing layer upon layer, and a gap is left between two adjacent flame-proof sheets. A movable closing plate of a valve orifice is arranged in the valve cavity, a spring whose two ends are respectively pressed on the panel and the closing plate of the valve orifice are arranged between the panel and the closing plate of the valve orifice of the valve, and a ring-shaped flame-proof device is sleeved on the outside of the closing plate of the valve orifice. The ring-shaped flame-proof device is formed by the superposition of a plurality of sheets of flame-proof device, buckling passages are formed between the two adjacent sheets of flame-proof device, and a guiding structure which plays a guiding role for the closing plate of the valve orifice is arranged on the flame-proof device. The invention has the advantages of safe use, wonderful flame blow-out performance, sensitive closure and starting, and long service lift.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an 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. [0003] Common explosion-proof valves such as Chinese Patent Application No. 200620040829.5 disclose "an explosion-proof valve", which discloses a valve seat, a valve cover that is fixedly connected with the valve seat and forms a valve cavity with the valve seat, and is tightened by a spring in the valve cavity. The valve plate pressed on the valve seat, and the flame retardant, the flame retardant is composed of a...
