Major label description in figure:

Prior art part: 1 vacuum valve, 11 bodies, 111 putting chambers, 112 through holes, 12 cylinder assemblys, 121 pistons, 122 piston rods, 123 gates, 124 connecting rods, 125 shroudings, 126 back-pressure ratches;

The utility model part: 2 vacuum valves, 21 bodies, 211 putting chambers, 212 pivot ears, 2121 connecting rods, 213 vents, 214 chutes, 22 cylinders, 221 pistons, 222 piston rods, 2221 connecting rods, 223 rocking arms, 2231 connecting rods, 224 flashboards, 2241 lugs, A base plate, 225 protruding seats, 226 pulleys.

Five, embodiment

Consult Fig. 4, Fig. 5, shown in Figure 6, be the utility model stereochemical structure side cutaway view, main pseudosection and operating state side cutaway view; This vacuum gate valve 2 includes body 21, cylinder 22; Wherein, cylinder 22 is located at body 21 tops, cylinder 22 inside be provided with can upper and lower displacement piston 221, piston 221 central authorities are provided with can run through the piston rod 222 that enters body 21 inner putting chambers 211, in order to make piston rod 222 can drive the action that flashboard 224 carries out curved side sealing vent 213, be provided with rocking arm 223 in its end by connecting rod 2221; rocking arm 223 then is connected with the lug 2241 that is located at flashboard 224 upper ends by connecting rod 2231 with 224 on flashboard; flashboard 224 1 sides are provided with a pivot ear 212 by connecting rod 2121; pivot ear 212 is located at vent 213 inner and upper; when desire is used vacuum gate valve 2 as Twoway valves; only need be; at this moment by a base plate A with 213 sealings of body 21 below vents, 224 upper and lower displacements that can utilize piston rod 222 of flashboard, and open closed with carrying out arc in flashboard 224 vents 213 1 sides; As shown in Figure 4, as shown in Figure 6, both sides can communicate during unlatching when closed, take over so that dock 180 degree.

Consult Fig. 7, Fig. 8, shown in Figure 9, for the utility model operating state side cutaway view, another example structure figure, another implements movement state diagram; Just the putting chamber 211 in its body 21 of the utility model also can be provided with flashboard 224 in piston rod 222 ends, its structure is to utilize the protruding seat 225 that is located at flashboard 224 tops, by connecting rod 2221 with its two connection, in order to make the flashboard 224 can positioning sliding, be provided with lug 2241 in flashboard 224 both sides, lug 2241 is provided with pulley 226,226 positioning slidings in the chute 214 that body 21 putting chambers 211 are offered of this pulley, during use, one vent 213 of body 21 both sides can be sealed the vent 213 of a side by base plate A, when piston rod 222 carries out knee-action, 224 on flashboard can directly form closed shape to lower seal vent 213 (bottom surface), as Fig. 7, shown in Figure 8; When piston rod 222 during, 213 unlatchings of one side and bottom air vent to top offset, so liquid gas can be by down toward side, or by side down, as shown in Figure 9, so its Twoway valves can dock 90 adapters of spending.

Consult shown in Figure 10, be the movement state diagram of the utility model as three-way valve, it is different from part shown in Figure 9, be to be located at body 21 side vents 213 to remove, at this moment, when flashboard 224 lifted, a large amount of liquid gas then can be by vent 213 dealings of bottom or both sides, so, the three-way valve that becomes capable of being combined.

The advantage of the utility model vacuum gate valve is, it can be used as Twoway valves or need be converted into three-way valve according to using, it is to cooperate the vent base plate, utilize piston rod to be connected by rocking arm with flashboard and flashboard one side is provided with the structural design of pivot ear, make flashboard form the function of arc skew sealing, or by the pulley of flashboard both sides and the slip of chute location and fixing of tailpiece of the piston rod and the protruding seat of flashboard, make it carry out straight line and move up and down, thus the adapter that can dock 90 degree or 180 degree.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
