Embodiment Construction

[0027] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1-5 As shown, this embodiment proposes a fire retardant valve core 1 of a motor vehicle exhaust spark extinguisher. The fire retardant valve core 1 includes a front valve core 101 , an intermediate impeller 102 and a rear valve core 103 arranged coaxially. The front valve core 101 is connected with the rear valve core 103 to form a cavity, and the middle impeller 102 is rotatably arranged in the cavity.

[0029] Wherein, the front valve core 101 , the middle impeller 102 and the rear valve core 103 are connected through a shaft sleeve.

[0030] Specifically, for ease of installation, the shaft sleeve includes a connected first shaft sleeve 104 and a second shaft sleeve 105 , and the first shaft sleeve 104 and the second shaft sleeve 105 are connected and fixed by a fixing member, whic...

Abstract

The invention discloses a motor vehicle exhaust spark arrester and a fire resistant valve core. The fire resistant valve core comprises a front valve core, a middle impeller and a rear valve core; thefront valve core and the rear valve core form a cavity; the middle impeller is rotatably arranged in the cavity; when exhausting, gas and spark are exhausted to the middle impeller; the gas drives the middle impeller to rotate; in a rotating process of the middle impeller, on one hand, the spark impacts the middle impeller to realize the extinction of the spark; on the other hand, the impeller drives the gas to flow and exhaust. Therefore, the air outlet of the fire resistant valve core is more smooth; the back pressure of an engine is reduced; the use efficiency of fuel is improved; the permeability of exhaust emission is improved; the extinction of the spark can be ensured; and the safety of a combustible and explosive place is further improved.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle exhaust spark extinguishing, and in particular relates to a motor vehicle exhaust spark extinguisher and a fire retardant valve core. Background technique [0002] At present, the motor vehicle exhaust spark extinguisher is applied at the end of the tailpipe of the automobile exhaust pipe. The special structure in the spark extinguisher is used to block the sparks generated in the exhaust tailpipe, so that the vehicle can enter various occasions (flammable areas) Explosive factories, gas stations, gas stations, oil depots and other regional places) have safety guarantees during operation, which can effectively reduce the accident rate of fire. If the spark arrester is unqualified, there will be serious safety hazards. Once an accident occurs, it will be impossible make up. [0003] However, most of the existing spark extinguishers use filter screens or other fixed structures to extinguish t...
