Present embodiment in use, the quick-fried relief opening sealing and fixing of the vapour of the quick-fried device of seal disc 1 corresponding vapour is installed (as adopting the flange connection as shown in Fig. 1, also can adopt welding to wait other modes), first solenoid valve is communicated with hydraulic power (hydraulic power is not shown in the drawings), second solenoid valve is communicated with oil drain passage, and oil drain passage is communicated with (oil sump tank is not shown in the drawings) with oil sump tank.During work, when the needs throttle down, control second solenoid valve and be in closed condition, controlling first solenoid valve opens, hydraulic oil enters cylinder body 5 by first oil through 55, and hydraulic oil promotes piston 51 and compression press spring 53, and valve body 31 stretches into valve opening 11 and valve opening 11 is sealed afterwards.At this moment can begin to boost in the quick-fried device of vapour, because the pressure effect of hydraulic power, valve can't be opened because of the air pressure in the quick-fried device of vapour.To begin vapour quick-fried when needs, when namely opening valve, control first solenoid valve and be in closed condition, controlling second solenoid valve opens, under the acting in conjunction power of steam to the thrust of the thrust of

valve body

31 and 53 pairs of pistons 51 of stage clip, hydraulic oil passes back into oil sump tank from second oil through 56, and valve body 31 quick regressions are also left valve opening 11, finish the quick unlatching of valve.At this moment the damping device of four discrete bumper post 71 formations cushions valve body dish 3.The effect of vent 57 is the gas in the cylinder body 5 not to be sealed when piston 51 moves back and forth in the present embodiment, to reduce piston 51 running resistances, vent 57 is not limited to be arranged on cylinder body 5 sidewalls, and vent 57 also can constitute like this: allow in the position that piston rod 52 passes cylinder body 5 and leave the gap between piston rod 52 and the cylinder body 5.

Because the existence of stage clip 53, in the valve opening process, the thrust of stage clip 53 makes the process of valve opening faster (taking the valve opening time that records through high-speed camera is 1/80s).Adopt small one and large one oil through of two sectional areas in addition, namely first oil through 55 and second oil through 56 are because need bigger flow so that piston 51 rollback fast in opening the valve process, and the process of throttle down does not have requirement fast.In the present embodiment, the head of valve body 31 is taper, and when opening the valve process and just begun, when namely valve body 31 had just begun to break away from valve opening 11, steam can outwards penetrate along conical surface, faster pressure release like this.Present embodiment medi-spring tube 531 is not necessary, and the effect of spring strut 531 mainly is to replace piston rod 52 as the matrix that stage clip 53 is overlapping, and makes stage clip 53 non-warping in telescopic process.

The quick-fried device of the utility model vapour with in the quick open valve in order to realize that when valve body 31 contacts with valve opening 11 valve body 31 can be with valve opening 11 sealings, valve body 31 can also be such with valve opening 11: the diameter of valve body 31 is greater than the diameter of valve opening 11, and valve body 31 is a circular plate; Perhaps the diameter of valve body 31 is greater than the diameter of valve opening, and valve opening 11 is provided with chamfering, and the wall of the head of valve body 31 and this chamfer surface coincide.In the prior art, utilize an entity that the structure of a hole sealing is comparatively common.

The quick-fried device of the utility model vapour as shown in Figure 2 is with second embodiment of quick open valve (simultaneously referring to Fig. 3), and itself and first embodiment's difference is: the head of valve body 31 is sphere shape in the present embodiment; Valve body dish 3 all is connected with each slide bar 2 by linear bearing 6 in the present embodiment, so equally also makes valve body dish 3 to slide along slide bar 2; Damping device in the present embodiment is ring washer 7, and ring washer 7 is coaxial with piston rod 52; In addition, except stage clip 53, the side away from seat board 4 of cylinder body 5 inherent pistons 51 is provided with extension spring 54 in the present embodiment, and extension spring 54 is connected with piston 51; First oil through 55 and second oil through 56 all are arranged on the end face of cylinder body 5 in the present embodiment.The using method of present embodiment is identical with first embodiment with working procedure, does not repeat them here.The sort of discrete damping device during employing ring washer 7 is implemented than first as damping device in the present embodiment, can be in all directions balanced, symmetrical ground buffering, guarantee that valve body dish 3 is vertical with slide bar 2 and do not distort all the time, prevents that valve body dish 3 is because of distortion heavy wear and reduction of service life.Extension spring 54 is similar with the effect of stage clip 53 in the present embodiment, all can give the active force that 51 1 in piston is pulled back piston rod 52 behind valve closing.Valve body dish 3 all is connected with each slide bar 2 by linear bearing 6 in the present embodiment, and linear bearing 6 can alleviate frictional force, and reduces wear.Extension spring 54 can be used simultaneously with stage clip 53 in the present embodiment, also can only adopt one.The quick-fried device of the utility model vapour can be the annular ring of being made by rubber-like material such as rubber with the damping device of mentioning in the quick open valve, also can be existing buffer in the prior art, as hydraulic buffer.In addition, the radical of slide bar 2 also is not limited to four, can be at least two.What deserves to be mentioned is in addition, for the quick-fried device of vapour that the quick-fried relief opening of a plurality of vapour is arranged, be 201110177699.5 as the applicant at the application number that proposes before, application publication number is CN102294200A, Shen Qing Publication day is the quick-fried devices of the disclosed a kind of many mouthfuls of disengaged vapors of the Chinese invention patent application on December 28th, 2011, need to use a plurality of valves to open the valve process simultaneously, in order to guarantee out the synchronism of valve, can utilize the two or more oil throughs of same electromagnetic valve, be that first oil through in two or more cylinder bodies is communicated to first solenoid valve jointly, and second oil through is communicated to second solenoid valve jointly.

Above-described embodiment is described preferred implementation of the present utility model; be not that 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.
