In one embodiment, as shown in Figure 3 and Figure 4, the vacuum valve 330 includes valve body 333, the first barrier flaps 331 With the second barrier flaps 332, the valve body 333 offers the first connected entrance 334, and first barrier flaps 331 offer the second company Port 335, and first barrier flaps 331 are fixedly installed in first connected entrance 334, second barrier flaps 332 are lived Dynamic be arranged in first barrier flaps 331 and activity is connected to second connected entrance 335, for example, second barrier flaps 332 are movably set in one side of first barrier flaps 331 towards the vavuum pump 310, when vavuum pump 310 works, such as Fig. 4 Shown, due to vacuum tube 320 relatively low near 310 one end air pressure of vavuum pump so that the second barrier flaps 332 depart from the first barrier flaps 331, so that the second connected entrance 335 is opened, and then causes the air in vacuum tank 100 to be extracted out by vavuum pump 310, and work as After vavuum pump 310 quits work, as shown in figure 5, the second barrier flaps 332 will be closely attached in the first barrier flaps 331, and due to now In vacuum tank 100, air pressure is relatively low, and the second barrier flaps 332 are tightly adsorbed in the first barrier flaps 331, so that second connects Port 335 is closed so that vacuum tank 100 is sealed.

In order to improve the seal of the vacuum valve 330, for example, the first barrier flaps 331 are made up of elastomeric flexible material, example Such as, the second barrier flaps 332 are made up of elastomeric flexible material, and for example, the elastomeric flexible material is rubber, so, due to the first resistance Partition 331 is made up of soft material with the second barrier flaps 332, therefore, easily curved under the vacuum action by vavuum pump 310 Bent so that the second connected entrance 335 is opened, and after vavuum pump 310 quits work, the second barrier flaps 332 are made due to natural resiliency With and be close to the first barrier flaps 331 so that the second connected entrance 335 is closed.

For example, as shown in Figure 3 and Figure 4, the first connected entrance 334 is circle, and for example, the first barrier flaps 331 are circle, example Such as, the second barrier flaps 332 are circle, and for example, the second connected entrance 335 is circle, for example, second barrier flaps 332 with described First barrier flaps 331 are parallel, and for example, 332 activity of the second barrier flaps is connected to the surface of first barrier flaps 331, example Such as, second barrier flaps 332 are connected with first barrier flaps 331 by dowel 336, and for example, the dowel 336 connects The edge of second barrier flaps 332 is connected to, specifically, the second connected entrance 335 is opened in the middle part of the first barrier flaps 331, and First barrier flaps 331 are connected by the dowel 336 at edge with the second barrier flaps 332, for example, dowel 336 radial around Second barrier flaps 332 are arranged, and for example, the dowel 336 is made up of elastic soft material, and for example, the dowel 336 is rubber Glue muscle, for example, the dowel 336 is made up of polyurethane rubber, and the dowel 336 that rubber is made has good elasticity and tough Property, after the strength suction for being subject to vavuum pump 310, dowel 336 is stretched, and the good toughness of dowel 336 makes which be difficult to be drawn Disconnected, under pull of vacuum effect, the second barrier flaps 332 depart from the first barrier flaps 331, after vavuum pump 310 stops, dowel 336 Recover shape under natural resiliency effect, the second barrier flaps 332 are attached at the first barrier flaps under the elastic reaction of dowel 336 331 surfaces so that the second connected entrance 335 is sealed.

In order that the second barrier flaps 332 can be close in the second barrier flaps 332, for example, the length of dowel 336 is not It is more than the radius of first barrier flaps 331 and the difference of the radius of second barrier flaps 332, for example, the first barrier flaps 331 Radius of the radius more than the second barrier flaps 332, for example, the length of dowel 336 be equal to the radius of first barrier flaps 331 with The difference of the radius of second barrier flaps 332, for example, the length of dowel 336 less than first barrier flaps 331 radius with The difference of the radius of second barrier flaps 332, as the length of dowel 336 is less than or equal to the radius of the first barrier flaps 331 With the difference of the radius of the second barrier flaps 332, and cause dowel 336 when vavuum pump 310 does not work, still in tensioned state, So that the second barrier flaps 332 can be close to the first barrier flaps 331 under the elasticity of dowel 336.

In order to improve the second connected entrance 335 by property, it is to avoid when vavuum pump 310 works, the second barrier flaps 332 are abutted Cause the second connected entrance 335 open in the first barrier flaps 331, for example, as shown in figure 4, first barrier flaps 331 are opened up There are some gaps 337, for example, some gaps 337 are arranged around second connected entrance 335, for example, some gaps 337 are arranged radially around second connected entrance 335, so, under the vacuum action for being subject to vavuum pump 310, the first resistance Partition 331 produces deformation, so that gap 337 becomes big, and then causes air circulation, with the circulation of air so that second Barrier flaps 332 and the first barrier flaps 331 produce gap, and then cause air passage rates very fast, by the second connected entrance 335 Throughput increases, and then causes the first barrier flaps 331 bigger with the gap of the second barrier flaps 332, so as to improve the second connection Mouthfuls 335 by property.For example, the diameter of the second connected entrance 335 is less than the second barrier flaps 332 with the length sum in gap 337 Diameter, so, when vavuum pump 310 does not work, the second barrier flaps 332 can will be close to the second connected entrance 335 and gap 337 Envelope.
