Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figures 1 to 3, the concentration control valve stand in this embodiment, including valve body 1, leans at valve body 1
The side of nearly valve block arranges the wear plate 2 of resistance to anaesthetic corrosion, and in the present embodiment, wear plate 2 uses
Rulon series material is made, and utilizes wear-resisting, the decay resistance of this kind of material can reduce valve seat entirety and valve block
Between friction, prevent valve seat be anesthetized agent corrosion, extend valve seat service life.
As in figure 2 it is shown, arrange wear plate mounting groove 11 on valve body 1, this wear plate mounting groove 11 has an end
Face 111 and the annular nib 112 being arranged on bottom surface 111, in the present embodiment, wear plate mounting groove
11 is circular groove, its bottom surface 111 arranges five the first pores 12 passed through for anesthetic vapor, each
The peripheral all annulars of first pore 12 arrange seal boss 13, and this seal boss 13 sets in integral type with valve body 1
Putting, i.e. direct punch forming seal boss 13 on valve body 1, so makes the sealing being molded on valve body 1
The intensity of boss 13 is higher, and the height of seal boss 13 is less than the degree of depth of wear plate mounting groove 11 simultaneously, i.e.
The height of seal boss 13, less than the height of chimb 112, so makes wear plate 2 can be placed to wear plate peace
In tankage 11.
As it is shown on figure 3, wear plate 2 entirety is rondelle, it has the side 21 of annular, this wear plate 2
It is placed in wear plate mounting groove 11, and the chimb of the side 21 of wear plate 2 and wear plate mounting groove 11
Also there is between 112 gap 4, make this is because wear plate 2 uses rulon series material, and this
Plant the serial material deflection when the variations in temperature deflection more than valve body 1, the most under the high temperature conditions
When using this valve seat, without this gap 4, then wear plate 2 will be deformed by valve body 1 crimp
After wear plate 2 and the valve block of concentration regulation valve between contact will not be smooth, gap can be produced, in concentration
During regulation valve uses, gas can cause concentration to regulate from the slot leakage between wear plate 2 and valve block
Valve can not normally use.
Wear plate 2 arranges five second pores 22 corresponding with the first pore 12, it addition, wear plate
Also being uniformly distributed four countersunk screw hole 23 on 2, corresponding countersunk screw hole 23 is at wear plate mounting groove 11
Bottom surface 111 arranges four screw connecting holes 14, and wear plate 2 passes sunk screw by four fixing screws 3
Hole 23 is fixed in wear plate mounting groove 11.
The assembling procedure of concentration control valve stand is as follows:
The first step: being placed in wear plate mounting groove 11 by wear plate 2, rotating wear-resistant sheet 2 makes the second pore
22 alignment the first pores 12；
Second step: use clamp system to be extruded with wear plate 2 by valve body 1, it is ensured that seal boss 13 is expressed to
In wear plate 2；
3rd step: use identical power to be fixed on through countersunk screw hole 23 by fixing screw 3 after having extruded
In screw connecting hole 14, complete the installation of concentration control valve stand.
Screw connecting hole 14, countersunk screw hole 23, the quantity of fixing screw 3 are not limited to described in above-described embodiment
Four, it is also possible to be five, six etc., it is only necessary to be uniformly distributed.
The quantity of the first pore 12 and the second pore 22 is also not necessarily limited to five described in above-described embodiment, its number
Amount is that the needs according to concentration regulation valve set.
Seal boss 13 be not limited to described in above-described embodiment with valve body 1 in integral structure, it is also possible to valve
Body 1 is in split-type structural, and such as, seal boss 13 can be the ring part being centered around outside the first pore 12
Part, it can be connected with valve body 1 by welding manner, and seal boss 13 can select the copper in metal material
Manufacture, additionally seal boss 13 may be used without O RunddichtringO, wear plate 2 and valve body 1 can be directly by close
It is peripheral that envelope boss 13 is clamped in the first pore 12, so can also realize the first pore 12 and the second pore
Sealing gap between 22.
The know-why of the present invention is described above in association with specific embodiment.These describe and are intended merely to explain this
The principle of invention, and limiting the scope of the invention can not be construed to by any way.Based on herein
Explaining, those skilled in the art need not pay performing creative labour can associate other tool of the present invention
Body embodiment, within these modes fall within protection scope of the present invention.
