Description
Technical field
The utility model is related to control valve, and in particular to one kind is used to make in hydrogen peroxide low-temperature plasma sterilizer
Flapper valve.
Background technology
Hydrogen peroxide（Chemical formula：H2O2）It is a kind of strong oxidizer, with stronger corrosivity.Exist using hydrogen peroxide
In such as sterilizing program of medicine equipment, hydrogen peroxide low-temperature plasma sterilizer is after disinfecting action is completed, hydrogen peroxide quilt
Vavuum pump directly detaches vacuum cavity.When vacuumizing, in order to maintain the vacuum state in sterilized instrument, in no Valve controlling
In the case of, vacuum extractor will be operated always, otherwise will make gas backflow.So on the one hand to waste compared with multiple-energy-source,
Another aspect hydrogen peroxide also can produce influence to the cavity and part of vacuum extractor, reduce its service life.Using valve
During control, due to being worked under hydrogen peroxide environment, the own structural characteristics of existing structure electromagnetic barriers valve are added, there is valve body
The problem of perishable, low shut-off reliability, high fault rate and high cost.
The content of the invention
Technical problem to be solved in the utility model is：There is provided a kind of reliable corrosion-resistant, shut-off, fault rate and cost low
Hydrogen peroxide low-temperature plasma sterilizer mechanical shutter valve.
Technical solution of the present utility model is：Hydrogen peroxide low-temperature plasma sterilizer mechanical shutter valve, it is
The combined member connected and composed by flapper valve and solenoid electric valve by threeway, flapper valve is made up of valve chest and silica gel baffle plate,
Valve chest is one in the ducted body of valve pocket swelled provided with two ports and one, two ports and is connected with threeway, another
Individual to be used for and be evacuated reservoir, the valve pocket one side adjacent with being evacuated container is for sealed sealing plane, separately
By-pass portion is simultaneously provided with the inner edge of port, silica gel baffle plate, which is placed in the valve pocket of flapper valve, cooperatively forms sealing knot with sealing plane
Structure is kept off between two ports of valve chest, and flapper valve and solenoid electric valve are connected with a port of threeway respectively, threeway
3rd port is used to be connected with vacuum extractor, the other end and atmosphere of solenoid electric valve.
It is of the present utility model to have the technical effect that：It has the advantages that reliable corrosion-resistant, shut-off, fault rate and cost are low, tool
There is higher service life, maintenance, operating cost and the service life for improving complete machine of complete machine can be reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, hydrogen peroxide low-temperature plasma sterilizer mechanical shutter valve, is by flapper valve 1 and Electromagnetic Control
The combined member that valve 2 is connected and composed by threeway 3, flapper valve 1 is made up of valve chest 4 and silica gel baffle plate 5, valve chest 4 be provided with
One in the ducted body for the valve pocket 6 that two ports and one swell, two ports is connected with threeway 3, and another is used for and quilt
Vacuum-pumping container is connected, and the one side adjacent with being evacuated container of valve pocket 6 is that another side is in end for sealed sealing plane 7
By-pass portion 8 is provided with intraoral edge, silica gel baffle plate 5 is placed in the valve pocket 6 of flapper valve 1 cooperatively forms sealing structure with sealing plane 7
Gear is between two ports of valve chest 4, and a port of flapper valve 1 and solenoid electric valve 2 respectively with threeway 3 is connected, threeway 3
The 3rd port be used for be connected with vacuum extractor, the other end and atmosphere of solenoid electric valve 2.By-pass portion 8 makes air-flow
Can not by silica gel baffle plate 5 stop.
The valve pocket 6 of the flapper valve 1 is circular cylindrical cavity, and the silica gel baffle plate 5 is circular plate body.
The course of work, solenoid electric valve 2 is closed, and vacuum pump startup is vacuumized to vacuum tank, at this moment, flapper valve 1
Open, the gas in vacuum tank is extracted by the by-pass portion 8 of flapper valve 1, is reached after requirement, and solenoid electric valve 2 is opened
Open, air enters, at this moment, because vacuum tank is in negative pressure state, after solenoid electric valve air inlet, 5 liang of silica gel baffle plate
Side forms pressure differential, and silica gel baffle plate 5 can be drawn onto the port blocked and connected with vacuum tank on sealing plane 7 rapidly, turns off true
Empty pump, by the sealing of flapper valve 1, vacuum tank just maintains the vacuum state of negative pressure always.
