Description
Technical field
The utility model belongs to the fixed valve plug of oxygenerator and the installing area of valve body, is on one kind oxygen processed specifically
The fixed valve plug pressuring flat device of machine.
Background technology
In the market, the nitrogen oxygen separating method for oxygenerator mainly have electromagnetism seperating vale, solenoid-driven it is pneumatic
Valve, ceramic core rotating separation valve etc.；Although electromagnetism seperating vale and Electromagnetic Drive pneumatic operated valve materials are easy, exist cost compared with
The shortcomings of high, driving air pressure is larger and needs extra drive.Ceramic core rotating separation valve largely solves electricity
The shortcoming of Magneto separate valve and Electromagnetic Drive pneumatic operated valve, but because its movable valve plug and fixed valve plug are ceramics, both rub at circulation rotating
Wipe, use for a long time can produce violent sound；Further, since the coefficient of friction of ceramics is big, contact of the movable valve plug with fixed valve plug
If rough between face can cause severe friction, so as to cause to kill the generation of phenomenon, the service life of product is influenceed.Therefore,
Chinese patent CN 205578787U disclose a kind of nitrogen oxygen circulation valve, the rotary valve include a fixed valve plug 10 (as shown in Figure 1) and
One valve body 20 (as shown in Figure 2), is provided with five column caps 21 in the valve body, five through holes 11 are correspondingly provided with fixed valve plug 10.Peace
, it is necessary to fixed valve plug 10 is fixedly mounted on valve body 20 during dress, movable valve plug is installed in rotation on fixed valve plug 10 again then.
Therefore, the flatness requirement to fixed valve plug 10 and movable valve plug is high.The installation method of existing fixed valve plug 10 and valve body 20, generally
It is that fixed valve plug 10 is placed on valve body 20, then fixed valve plug 10 is pressed against on valve body 20.Due to five column caps in valve body 20
21 in approximately the same plane, and fixed valve plug 10 is placed on when on valve body 20, if not pushing completely, fixed valve plug 10 is not easy pressure
It is flat, when coordinating with movable valve plug, easily there is gas leakage, cause the oxygen concentration of rotary valve inadequate so that two molecular sieve tanks to cut gas uneven,
Influence oxygen effect processed.
Utility model content
The purpose of this utility model is to provide a kind of fixed valve plug pressuring flat device of oxygenerator, with solve existing fixed valve plug and
The problem of fixed valve plug out-of-flatness when valve body is installed.
To achieve the above object, the utility model uses following technical scheme：
A kind of fixed valve plug pressuring flat device, including the top board, pressing plate and the base plate that set from top to bottom successively and located at described
The lead column of top board, pressing plate and base plate both sides, respectively longitudinally through pressing plate, upper end is fixed on top board two lead columns, and lower end is solid
It is scheduled on base plate, and two lead columns are symmetrical arranged, the base plate is provided with a jack, and the piston rod of jack is fixed on pressing plate
On, it is arranged with compression spring in the lead column between the pressing plate and top board.
According to the utility model, fairlead is arranged with the lead column between the base plate and pressing plate, so that pressing plate is relative
More balanced when lead column is slided up and down, it is more stable.
According to the utility model, the jack is located at the middle part of base plate.
According to the utility model, the jack is hydraulic jack, mechanic jacks etc..
Fixed valve plug pressuring flat device of the present utility model, its advantage is：Simple structure, it is easy to operate, it can be ensured that fixed
Valve element is fixedly mounted on when on valve body, and fixed valve plug can be pushed completely, so that it is guaranteed that fixed valve plug is in state of applanation.

Fig. 2 is the structural representation of valve body.
Fig. 3 is the front schematic view of fixed valve plug pressuring flat device of the present utility model.
Fig. 4 is the side schematic view of fixed valve plug pressuring flat device of the present utility model.
Specific embodiment
Below in conjunction with specific accompanying drawing, the fixed valve plug pressuring flat device to a kind of oxygenerator of the present utility model is made further in detail
Explanation.
As shown in figure 3, being a kind of fixed valve plug pressuring flat device of the present utility model, including the top board for setting from top to bottom successively
1st, pressing plate 2 and base plate 3, and located at the lead column 4 of top board 1, pressing plate 2 and the both sides of base plate 3, two lead columns 4 respectively longitudinally through
Pressing plate 2, upper end is fixed on top board 1, and lower end is fixed on base plate 3, and two lead columns 4 are symmetrical arranged, and the base plate 3 is provided with
One jack 5, the piston rod 51 of jack 5 is fixed on pressing plate 2, is arranged in the lead column 4 between the pressing plate 2 and top board 1
There is compression spring 6.
Fairlead 7 is arranged with lead column 4 between the base plate 3 and pressing plate 2, so that pressing plate 2 is oppositely oriented post about 4
More balanced during slip, it is more stable.
The jack 5 is located at the middle part of base plate 3.
The jack 5 is hydraulic jack, mechanic jacks etc..
By taking hydraulic jack as an example, when using, fixed valve plug is put into valve body, then valve body is placed on pressing plate 2, up time
Pin rotary switch 9, locks jack 5, pulls handle 8 (as shown in Figure 4), drives hydraulic pump, hydraulic system transmission, piston rod 51
It is slow to rise, so that pressing plate 2 slowly rises, until the upper surface of valve body and fixed valve plug is resisted against on top board 1, fixed valve plug and valve
Body is flattened and completed, and at the same time, pressing plate 2 pushes compression spring 6；Then, rotate counterclockwise switch 9, jack 5 is unlocked, compression
The stress of spring 6 is released, and is recovered to original state；Finally, valve body is removed from pressing plate 2.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
