And the through hole 5 of one end of valve rod 2 and the valve seat 1 coordinates with through hole 5 described in opening and closing of fault, and the other end of valve rod 2 stretches out
In outside the stomata 4；Spring 6 is equipped on the valve rod 2, the spring 6 is used to that the valve rod 2 to be driven to move to the through hole 5
It is dynamic.The vacuum valve of the utility model does not possess matching relationship between valve deck 3 and valve seat 1, valve deck 3 is only located on valve seat 1,
Fixing seal is carried out by the way that valve deck 3 and valve seat 1 are installed on container 15, makes to be very easy under dismounting between valve deck 3 and valve seat 1
It cleans, use can thoroughly clean all parts of vacuum valve later, avoid peculiar smell；Meanwhile valve rod 2 is in the gas of valve deck 3
In hole 4, simple in structure by the through hole 5 of 6 driving stem of spring, 2 seal valve seat 1, sealing effect is good, and exhaust and pumping are in valve deck
It can complete, operate more convenient at 3 stomata 4.
As shown in Figure 1, the edge of the valve seat 1 is equipped with the baffle ring 7 coordinated with the step surface 16 of the container 15；The valve
The edge of lid 3 is equipped with the mounting post 8 detachably coordinated with container 15.By baffle ring 7 valve seat 1 is made to be pressed in the step surface 16 of container 15
On, then by mounting post 8 removably valve deck 3 is fixed on container 15, make valve deck 3 and valve seat 1 with container 15 removably
Connection is fixed, not only cleaning easy to disassemble, but also can guarantee the leakproofness between valve deck 3 and valve seat 1.
As shown in figure 3, having block 9 on the valve rod 2, one end of the spring 6 is withstood on the block 9, the bullet
On the valve deck 3 on the other end top of spring 6.Holddown spring 6 is coordinated by block 9 and valve deck 3, allows spring 6 more stably
Elastic force is provided to valve rod 2, valve rod 2 is enable to be maintained at the state of the through hole 5 of closed valve seat 1, ensures that the vacuum of container 15 is air tight.
The lateral edges of the block 9 offer circular or U-shaped groove 10.When opening vacuum valve, valve rod 2 lift off a seat 1 through hole 5
During place, groove 10 can make air very swimmingly by through hole 5, improve air and pass through speed.
As shown in Fig. 2, the upper surface of the valve deck 3 is equipped with to rotate the handle 11 of the valve deck 3.User can pass through
Swing handle 11 can rotate easily valve deck 3, convenient for vacuum valve is disassembled from container 15.
As shown in figure 3, there is the plug 12 of taper with described 5 matched one end of through hole on the valve rod 2.Pass through taper
Plug 12 and the through hole 5 of valve seat 1 coordinate, shape more matches between plug 12 and through hole 5, can effectively improve plug 12 to through hole
5 leakproofness.The gasket 13 of taper is equipped on the plug 12.Increase the sealing heat of taper on plug 12, it can be further
Improve leakproofness of the plug 12 to the through hole 5 of valve seat 1.
As shown in Figure 1, being equipped with sealing ring 14 between the valve deck 3 and valve seat 1, valve deck 3 and valve seat 1 can be further improved
Between leakproofness.
When being installed, valve seat 1 is placed at the blow vent of container 15 first, the baffle ring 7 on valve seat 1 is made to be pressed onto appearance
On the step surface 16 of device 15, then sealing ring 14 is put on valve seat 1, gasket 13 is attached on plug 12, then by 6 sets of spring
It is put at the through hole 5 of valve seat 1 on valve rod 2, then by valve rod 2, finally covers valve deck 3 on valve seat 1, make valve rod 2 from insertion valve
The stomata 4 of lid 3 is simultaneously stretched, and rotates valve deck 3, the mounting post 8 on valve deck 3 is made to snap onto in the L-shaped mounting groove 17 on container 15,
The structure of mounting groove 17 is as shown in Figure 4；So under the fixation of container 15, valve deck 3 compresses valve seat 1, makes valve deck 3 and valve
It is tightly sealed between seat 1, while spring 6 provides elastic force under the pressure of valve deck 3 to valve rod 2, makes the plug 12 of valve rod 2
The closure of through hole 5 of valve seat 1 is got up.15 inside of container and external necessary channel, the through hole 5 of valve seat 1 are sealed.Installation
Structure afterwards, as shown in Figure 1.
When needing to vacuumize container 15, the suction pipe of vacuum machine is set to 4 outer wall of stomata of valve deck 3, vacuum machine work
After form negative pressure, 15 air pressure inside of container overcomes 6 elastic force of spring that the plug 12 of valve rod 2 is open-top, and the through hole 5 of valve seat 1 is just beaten
It opens, 15 inner air of container will pass through the passage between the through hole 5 of valve seat 1 and the stomata 4 of valve deck 3, be drawn into vacuum machine
Interior, such container 15 can be evacuated.When reaching vacuum state in container 15,15 inside of container and vacuum machine air pressure phase
Deng, 6 elastic force of spring effect under, valve rod 2 is moved to valve seat 1, and the through hole 5 on valve seat 1 is closed by plug 12, from valve deck 3
On remove the suction pipe of vacuum machine, can be always held at the state of 1 through hole 5 of closed valve seat in 6 elastic force of spring effect lower valve rod 2, hold
Device 15 will be constantly in vacuum state, and the storage time for extending 15 interior items of container undergoes no deterioration.When user needs to take out
During article in container 15, it is only necessary on the surface of valve deck 3, one end that valve rod 2 is pulled to expose, make valve rod 2 lift off a seat 1 it is logical
Hole 5, the through hole 5 of stomata 4 and valve seat 1 that such extraneous air will pass through valve deck 3 are entered in container 15, treated inside and outside container 15
After air pressure balance, container 15 can be opened and take out article.
Vacuum valve is cleaned if necessary after use, can make valve deck 3 by rotating the handle 11 on valve deck 3
On mounting post 8 exited out of container 15 L-shaped mounting groove 17, valve deck 3 can be removed from container 15, due to vacuum valve
All parts between do not possess the relation of being fastenedly connected, after valve deck 3 is removed from container 15, other parts can be very
It easily takes off, all parts of such vacuum valve can be cleaned easily.
The above is only the better embodiment of the utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
