Abstract
The utility model provides a kind of plug-in valve of freeze dryer, including rubber valve body, and be tiltedly installed with gas in the middle part of the rubber valve body is provided with plastic rotor by rubber Switching-through channel, the end of the rubber valve body；The bottom sintering of the rubber Switching-through channel has ground glass converting interface, and the ground glass converting interface bottom is connected with lyophilized bottle.Using technical solutions of the utility model, greatly reduce because solid mechanical impurity caused by rubber, ageing of plastics reason so that the overall better tightness of freeze dryer, service life are obviously prolonged.
Description
Technical field
It the utility model is related to laboratory glassware technical field, more particularly to a kind of plug-in valve of freeze dryer.
Background technology
The general material of the existing plug-in valve of freeze dryer is rubber and plastics and the rotor of the polytetrafluoro material as rotor, its
Middle rubber and plastics are easy to aging and come off solid impurity, and pollution is produced to lyophilized product.Because aging easily causes sealing
Property reduce, the freeze dryer life-span is caused to have an impact.
Utility model content
The defects of in order to overcome the plug-in valve of prior art freeze dryer easy to aging, the utility model proposes a kind of sealing
By force, the plug-in valve of freeze dryer of freeze dryer service life can effectively be extended.
To achieve these goals, technical scheme is used by the utility model：
A kind of plug-in valve of freeze dryer, including rubber valve body, gas is tiltedly installed with the middle part of the valve body passes through rubber
Switching-through channel, the end of the rubber valve body are provided with plastic rotor；The bottom sintering of the rubber Switching-through channel has frosted glass
Glass converting interface, the ground glass converting interface bottom are connected with lyophilized bottle.
Further, the rubber Switching-through channel is formed in one with the valve body.
Further, the plastic rotor one end rotation be installed on the rubber valve body end inside, wherein with institute
State and a strata polytetrafluoroethylene membrane is coated with the inwall of the end of the rubber valve body of the end thereof contacts of plastic rotor.
Further, the top of the ground glass converting interface is sintered in the bottom of the rubber Switching-through channel, the mill
The middle part of sand glass converting interface is bulbous passage, and the spherical channel lower end is the round table-like passage of decreasing pore size；It is described
Round table-like passage is plugged into the lyophilized bottle.Thus the more favourable lyophilized bottle of sealing, and row buffering can be entered to the dry powder of collection.
Using technical solutions of the utility model, greatly reduce because solid mechanical caused by rubber, ageing of plastics reason
Impurity so that the better tightness of freeze dryer, life-span are more permanent.
Brief description of the drawings
Fig. 1 is the plug-in valve arrangement schematic diagram of freeze dryer in the utility model specific embodiment.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model
As shown in Figure 1, in the utility model specific embodiment, a kind of plug-in valve of freeze dryer, including rubber valve body 1, rubber
What the middle part of valve body 1 was tiltedly installed with gas is provided with plastic rotor 3 by rubber Switching-through channel 2, the end of rubber valve body 1；
The sintering of bottom 21 of rubber Switching-through channel 2 has ground glass converting interface 4, and the bottom of ground glass converting interface 4 is connected with lyophilized bottle
5。
In the utility model specific embodiment, rubber Switching-through channel 2 is formed in one with rubber valve body 1.
In the utility model specific embodiment, it is preferable that one end rotation of plastic rotor 3 is installed on the end of rubber valve body 1
The inside at end 11, wherein with being coated with a strata tetrafluoro on the inwall of the end 11 of the rubber valve body 1 of the end thereof contacts of plastic rotor 3
Film.Plastic rotor 3 and the abrasion of the rubber after aging can effectively be reduced.
In the utility model specific embodiment, it is preferable that the top of ground glass converting interface 4 is sintered in rubber Switching-through channel
2 bottom 21, the middle part of ground glass converting interface 4 is bulbous passage 41, and the lower end of spherical channel 41 is decreasing pore size
Round table-like passage 42；The bottom of round table-like passage 42 is plugged into lyophilized bottle 5.Thus the circle of ground glass and decreasing pore size
Mesa-shaped passage 42 can more favorably seal lyophilized bottle 5, and spherical channel 41 can enter row buffering to the dry powder of collection.Institute in Fig. 1
The lyophilized bottle 5 shown is the schematic diagram for going back the bottom that unsealing is installed to round table-like passage 42.
Using technical solutions of the utility model, greatly reduce because solid mechanical caused by rubber, ageing of plastics reason
Impurity so that the overall better tightness of freeze dryer, service life are obviously prolonged.
The preferable embodiment of the utility model is these are only, but the scope of protection of the utility model is not limited to
This, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., should be included in this
Within the protection domain of utility model.
