Embodiment Construction

[0021] 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.

[0022] 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 consists of a panel 1, a seat plate 2, a valve plate 3, an inner flame retardant 4, an outer flame retardant 5, an inner layer flame retardant ring 6 and a surface layer flame retardant ring 13, etc.

[0023] Specifically, the seat plate 2 is annular and can be connected to the crankcase through the seat plate 2...

Abstract

The invention provides an explosion-proof valve, belonging to the field of mechanical technology. The invention solves the problem that a current explosion-proof valve can not extinguish flame completely in the explosion-proof valve. The explosion-proof valve comprises a panel, a base plate and an inner flame retardant device, which form a valve cavity provided with a valve plate forming a sealing space with the seat plate, a spring is arranged between the panel and the valve plate, and an outer flame retardant device is also fixed between the panel and the seat plate, both the outer flame retardant device and the inner flame retardant device are formed by alternatively stacking the front and the back of a plurality of circular sheets of the flame retardant devices, a plurality of channels communicating the valve cavity and the outside are formed by stacking the fronts of the sheets of the flame retardant devices, each channel is provided with at least two bends. The outer flame retardant device and the inner flame retardant device extend the flow route of flame and air flow, the explosion-proof valve has the advantages of safe use, good flame extinguishing property and long service life.

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...
