Description
Technical field
The utility model relates to a kind of stop valve, particularly relates to a kind of stop valve for the anti-explosion diesel engine inlet end.
Background technique
Anti-explosion diesel engine is applied to railless free-wheeled vehicle, monorail crane locomotive, the mine locomotives such as tooth road railer, the anti-explosion diesel engine monorail crane is usingd explosion-proof diesel units as power system, the anti-explosion diesel engine unit is mainly by the diesel engine body, cooling system, air inlet system and exhaust system, oil-fired system, shutdown systems and suspension system six parts form, because the applied working condition of anti-explosion diesel engine has higher requirements to fire-proof and explosion-proof, therefore be that inlet end or exhaust end at diesel engine all needs to install the device for back-fire relief, and also the air inlet stop valve should be set between fire retardant device and diesel engine intake mouth, when needs emergency cut-off diesel engine, by closing air inlet stop valve blocking-up air inlet, realize.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of anti-explosion diesel engine air inlet stop valve simple in structure, safe and reliable, easy and simple to handle.
The utility model anti-explosion diesel engine air inlet stop valve, comprise tubular valve pocket and spool video disc, described spool video disc is arranged in valve pocket by lower rotary shaft, wherein said lower rotary shaft upper end passes from valve pocket, and be fixedly connected with fork, described valve pocket upper end is fixedly connected with seal casinghousing by connecting rod, in described seal casinghousing, cylinder is installed, the piston rod of described cylinder is connected with upper rotating shaft by driving mechanism, be set with Returnning spring in described upper rotating shaft, the lower end of upper rotating shaft passes from the seal casinghousing lower end surface, and be fixedly connected with handle, be fixedly connected with driving lever on described handle, offer draw-in groove on described fork, described driving lever is positioned at draw-in groove.
The utility model anti-explosion diesel engine air inlet stop valve, be equipped with bearing between wherein said lower rotary shaft and valve pocket.
The utility model anti-explosion diesel engine air inlet stop valve utilizes cylinder and handle to control the spool video disc and rotates, and both can adopt pneumatic system to control the break-make of stop valve, also can manually control the stop valve break-make, and Security is higher, operates easier.
Below in conjunction with accompanying drawing, anti-explosion diesel engine air inlet stop valve of the present utility model is described further.
The accompanying drawing explanation
The plan view that Fig. 1 is the utility model anti-explosion diesel engine air inlet stop valve;
The side view that Fig. 2 is the utility model anti-explosion diesel engine air inlet stop valve.
Embodiment
As depicted in figs. 1 and 2, the utility model anti-explosion diesel engine air inlet stop valve comprises tubular valve pocket 1 and spool video disc 2, and spool video disc 2 is arranged in valve pocket 1 by lower rotary shaft 3, between lower rotary shaft 3 and valve pocket 1, bearing 12 is installed.Lower rotary shaft 3 upper ends pass from valve pocket 1, and are fixedly connected with fork 4.Valve pocket 1 upper end is fixedly connected with seal casinghousing 6 by connecting rod 5, and cylinder 7 is installed in seal casinghousing 6, and the piston rod of cylinder 7 is connected with upper rotating shaft 8 by driving mechanism.Be set with the Returnning spring (not shown) in upper rotating shaft 8, the lower end of upper rotating shaft 8 passes from seal casinghousing 6 lower end surfaces, and is fixedly connected with handle 9, is fixedly connected with driving lever 10 on handle 9, offers draw-in groove 11 on fork 4, and driving lever 10 is positioned at draw-in groove 11.
When anti-explosion diesel engine works, the cylinder charge that pneumatic system is interior to seal casinghousing 6, the piston rod of cylinder drives rotating shaft 8 by driving mechanism and rotates, and upper rotating shaft 8 is rotated by handle 9, driving lever 10, fork 4 and lower rotary shaft 3 band movable valve plug video discs 2, and the two ends of valve pocket 1 are communicated with.When anti-explosion diesel engine needs emergency shutdown to close; the unloading of pneumatic system control cylinder; upper rotating shaft 8 rotates backward under the active force of Returnning spring; thereby band movable valve plug video disc 2 rotates backward; make the closed at both ends of valve pocket 1; the suction port of anti-explosion diesel engine does not have gas to enter, and anti-explosion diesel engine quits work.The rotation of opening of spool video disc 2 also can be by operating grip 9 realizations.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
