Description
Technical field
The present invention relates to control valve, and in particular to used in a kind of sterilizer for hydrogen peroxide low-temperature plasma
Flapper valve.
Background technology
Hydrogen peroxide（Chemical formula：H2O2）It is a kind of strong oxidizer, with stronger corrosivity.Exist using hydrogen peroxide
As medicine equipment sterilizing program in, hydrogen peroxide low-temperature plasma sterilizer complete disinfecting action after, 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, will otherwise 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 of vacuum extractor and part, 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
Perishable, shut-off reliability is low, fault rate is high and high cost problem.
The content of the invention
The technical problems to be solved by the invention are：The mistake of a kind of reliable corrosion-resistant, shut-off, fault rate and low cost is provided
Hydrogen oxide low-temperature plasma sterilizer mechanical shutter valve.
Technical solution of the invention is：Hydrogen peroxide low-temperature plasma sterilizer mechanical shutter valve, it is by keeping off
The combined member that plate valve and solenoid electric valve are connected and composed by threeway, flapper valve is made up of valve chest and silica gel baffle plate, valve casing
Body is the ducted body for being provided with two ports and a valve pocket for swelling, and one in two ports is connected with threeway, another use
In be evacuated reservoir, the valve pocket one side adjacent with container is evacuated is the sealing plane for sealing, another side
By-pass portion is provided with the inner edge of port, silica gel baffle plate is placed in the valve pocket of flapper valve and cooperatively form sealing structure gear with sealing plane
Between two ports of valve chest, flapper valve and solenoid electric valve are connected with a port of threeway respectively, and the 3rd of threeway the
Individual port is used to be connected with vacuum extractor, the other end and atmosphere of solenoid electric valve.
The solution have the advantages that：It has the advantages that corrosion-resistant, shut-off reliable, fault rate and low cost, with compared with
Service life high, can reduce the service life of the maintenance, operating cost and the whole machine of raising of whole machine.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific 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, and valve chest 4 is to be provided with
The ducted body of the valve pocket 6 that two ports and swell, one in 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 container is evacuated of valve pocket 6 is the sealing plane 7 for sealing, and another side is in end
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 and cooperatively forms sealing structure with sealing plane 7
Between two ports of valve chest 4, a port of flapper valve 1 and solenoid electric valve 2 respectively with threeway 3 is connected gear, 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
Stopping for silica gel baffle plate 5 can not be received.
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, and after reaching requirement, solenoid electric valve 2 is opened
Open, air enters, at this moment, because vacuum tank is in negative pressure state, from 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 rapidly drawn onto on sealing plane 7 port blocked and connected with vacuum tank, turns off true
Empty pump, by the sealing of flapper valve 1, vacuum tank just maintains the vacuum state of negative pressure always.
