As a kind of preferred version of concentration adjustment valve base, described seal boss and described valve body adopt integral structure.Seal boss and valve body are adopted to integral structure, can increase the intensity of seal boss, ensure that seal boss is tightr with contacting of wear plate.
As a kind of preferred version of concentration adjustment valve base, described seal boss and described valve body adopt split-type structural.Seal boss and valve body are adopted to split-type structural, can, in the sealing ensureing between the first pore and the second pore, reduce the manufacture difficulty of valve seat.
As a kind of preferred version of concentration adjustment valve base, described seal boss adopts O RunddichtringO, and described O RunddichtringO is closely held between described wear plate and described valve body.
Preferably, described seal boss adopts O type rubber seal, is more preferably, and described seal boss adopts any one in O type viton seal ring, O type fluorosioloxane rubber sealing ring, O type neoprene packing circle, O type silicone rubber O-ring.
Preferably, described seal boss is the annular element being centered around outside described the first pore, and described seal boss can be combined with the bottom surface of wear plate mounting groove by welding manner, and described seal boss adopts metal material to make, be more preferably, described seal boss is made of copper.
Adopt seal boss to seal the gap between the first pore and the second pore, can avoid adopting bonding agent, can effectively prevent that the situation that bonding agent is corroded by anesthetis from occurring, and also can effectively prevent that wear plate from coming off from valve body, ensure the reliability of valve seat.
As a kind of preferred version of concentration adjustment valve base, the height of described seal boss is less than the degree of depth of described wear plate mounting groove.
The setting of seal boss is for after wear plate and valve seat are installed, and gapless between the first pore and the second pore, ensures that the gas that is entered into the second pore by the first pore does not produce leakage.
A kind of concentration adjustment valve, comprises valve seat and valve block, and described valve seat adopts concentration adjustment valve base as described above.Between valve seat and valve block, wear plate is set, can effectively alleviates the wearing and tearing between valve block and valve seat, extend the service life of concentration adjustment valve, make the adjusting of concentration adjustment valve can keep for a long time accurate using state.
Contrast prior art, beneficial effect of the present invention is: by wear plate being set at valve body near a side of valve block, this wear plate adopts high-abrasive material to make, can reduce the wearing and tearing between valve seat and valve block, extend the service life of valve seat and valve block, wear plate adopts resistant material to make simultaneously, in use, can effectively prevent that the situation that valve seat is corroded by anesthetis from occurring, further ensure the reliability of product.

Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention.
As shown in Figures 1 to 3, concentration adjustment valve base in this embodiment, comprise valve body 1, the wear plate 2 of resistance to anaesthetic corrosion is set near a side of valve block at valve body 1, in the present embodiment, wear plate 2 adopts rulon series material to make, and utilizes wear-resisting, the decay resistance of this kind of material can reduce the friction between valve seat entirety and valve block, prevent that valve seat from being corroded by anesthetis, extend the service life of valve seat.
As shown in Figure 2, wear plate mounting groove 11 is set on valve body 1, this wear plate mounting groove 11 has a bottom surface 111 and is arranged at the annular nib 112 on bottom surface 111, in the present embodiment, wear plate mounting groove 11 is circular groove, five the first pores 12 that pass through for anesthetic vapor are set on its bottom surface 111, in the peripheral all annulars of each the first pore 12, seal boss 13 is set, this seal boss 13 is integral type setting with valve body 1, i.e. direct punch forming seal boss 13 on valve body 1, the intensity that makes to be like this molded over the seal boss 13 on valve body 1 is higher, the height of seal boss 13 is lower than the degree of depth of wear plate mounting groove 11 simultaneously, be that the height of seal boss 13 is lower than the height of chimb 112, make like this wear plate 2 can be placed in wear plate mounting groove 11.
As shown in Figure 3, wear plate 2 entirety are rondelle, it has annular side 21, this wear plate 2 is placed in wear plate mounting groove 11, and also there is gap 4 between the side 21 of wear plate 2 and the chimb 112 of wear plate mounting groove 11, this is to be that rulon series material is made because wear plate 2 adopts, and the deflection of the material of this series in the time of variations in temperature is greater than the deflection of valve body 1, therefore while using this valve seat under hot conditions, if there is no this gap 4, wear plate 2 will be by valve body 1 crimp so, contacting between the wear plate 2 after distortion and the valve block of concentration adjustment valve can be not smooth, can produce gap, in the use procedure of concentration adjustment valve, gas can be from the slot leakage between wear plate 2 and valve block, cause concentration adjustment valve normally not use.
Five second pores 22 corresponding with the first pore 12 are set on wear plate 2, in addition, on wear plate 2, be also uniformly distributed four sunk screw holes 23, corresponding sunk screw hole 23 arranges four screw connecting holes 14 in the bottom surface 111 of wear plate mounting groove 11, and wear plate 2 is fixed in wear plate mounting groove 11 through sunk screw hole 23 by four hold-down screws 3.
The assembling procedure of concentration adjustment valve base is as follows:
The first step: wear plate 2 is placed in wear plate mounting groove 11, and rotating wear-resistant sheet 2 makes the second pore 22 aim at the first pore 12;
Second step: adopt clamp mechanism that valve body 1 and wear plate 2 are pushed, ensure that seal boss 13 is expressed in wear plate 2;
The 3rd step: pushed the identical power of rear employing hold-down screw 3 is fixed in screw connecting hole 14 through sunk screw hole 23, completed the installation of concentration adjustment valve base.
The quantity of screw connecting hole 14, sunk screw hole 23, hold-down screw 3 is not limited to four described in above-described embodiment, can also be five, six etc., only need to be uniformly distributed.
The quantity of the first pore 12 and the second pore 22 is also not limited to five described in above-described embodiment, and its quantity is to set according to the needs of concentration adjustment valve.
Know-why of the present invention has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, within these modes all will fall into protection scope of the present invention.
