Description
Technical field
The utility model is related to control valves, and in particular to one kind is used in hydrogen peroxide low-temperature plasma sterilizer make
Flapper valve.
Background technology
Hydrogen peroxide（Chemical formula：H2O2）It is a kind of strong oxidizer, there is stronger corrosivity.Exist using hydrogen peroxide
As medical instrument sterilizing program in, hydrogen peroxide low-temperature plasma sterilizer is after disinfecting action is completed, hydrogen peroxide quilt
Vacuum pump directly detaches vacuum cavity, and the content of hydrogen peroxide into vacuum pump crosses the service life of conference reduction vacuum pump, together
When certain influence is also had on environment.When vacuumizing, in order to maintain the vacuum state in sterilized instrument, controlled in no valve
In the case of, vacuum extractor will operate always, otherwise will make gas backflow.So on the one hand to waste compared with multiple-energy-source,
Another aspect hydrogen peroxide can also have an impact the cavity and component of vacuum extractor, reduce its service life.Using valve
During control, due to working under hydrogen peroxide environment, in addition the own structural characteristics of existing structure electromagnetic barriers valve, there are valve bodies
It is perishable, reliability is low for shut-off, high failure rate and it is of high cost the problem of.
The content of the invention
Technical problem to be solved in the utility model is：There is provided it is a kind of it is corrosion-resistant, shut-off is reliable, failure rate and at low cost
Hydrogen peroxide low-temperature plasma sterilizer hydrogen peroxide tap device assembly.
The technical solution of the utility model is：Hydrogen peroxide low-temperature plasma sterilizer hydrogen peroxide coupler group
Part, including flapper valve, solenoid electric valve, threeway and hydrogen peroxide decomposer, the housing of flapper valve and hydrogen peroxide decomposer is equal
A ducted body for expanding chamber is additionally provided with there are two port and centre position to set, the valve chamber of flapper valve is adjacent with a port
It is the sealing plane for sealing on one side, another side is equipped with by-pass portion at another port inner edge, is set in the valve chamber of flapper valve
There are silica gel baffle and sealing plane to cooperatively form sealing structure gear between two ports of flapper valve, hydrogen peroxide decomposer
Filtration with manganese sand body is equipped in cavity, flapper valve is equipped with one end of by-pass portion and solenoid electric valve connects respectively with a port of threeway
It connecing, the other end of flapper valve is used for and is evacuated reservoir, the other end and atmosphere of solenoid electric valve, and the of threeway
Three ports are connected with a port of hydrogen peroxide decomposer, another port of hydrogen peroxide decomposer is used for vacuumizing
Device connects.
The utility model has the technical effect that：It has the advantages that corrosion-resistant, shut-off is reliable, failure rate and at low cost, mistake
Hydrogen oxide be decomposed device decomposition, relevant device is allow to keep higher service life, can reduce complete machine maintenance, operation into
Originally with the service life of raising complete machine, it is also beneficial to the protection to ambient enviroment.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of the utility model flapper valve.
Specific embodiment
As illustrated in fig. 1 and 2, hydrogen peroxide low-temperature plasma sterilizer hydrogen peroxide tap device assembly, including flapper valve
1st, the housing of solenoid electric valve 2, threeway 3 and hydrogen peroxide decomposer 4, flapper valve 1 and hydrogen peroxide decomposer 4 is equipped with two
A port and centre position are additionally provided with a ducted body for expanding chamber 5, the valve chamber of flapper valve 1（Expand chamber 5）With a port phase
Adjacent one side is the sealing plane 6 for sealing, and another side is equipped with by-pass portion 7, the valve of flapper valve 1 at another port inner edge
Silica gel baffle 8 is equipped in chamber and sealing plane 6 cooperatively forms sealing structure gear between two ports of flapper valve 1, peroxidating
The cavity of hydrogen decomposer 4（Expand chamber 5）In be equipped with filtration with manganese sand body 9, flapper valve 1 is equipped with one end and the Electromagnetic Control of by-pass portion 7
A port of the valve 2 respectively with threeway 3 is connected, and the other end of flapper valve 1 is used for and is evacuated reservoir, solenoid electric valve
2 other end and atmosphere, the 3rd port of threeway 3 are connected with a port of hydrogen peroxide decomposer 4, hydrogen peroxide
Another port of decomposer 4 is used to be connected with vacuum extractor.By-pass portion 7 allows stop of the air-flow from silica gel baffle 8.
Filtration with manganese sand body 9 is made of manganese sand outsourcing tulle pouch.
The valve chamber of the flapper valve 1 is circular cylindrical cavity, and the silica gel baffle 8 is circular plate body.
It the flapper valve 1 and is evacuated between container and is additionally provided with bellows 10 and connects.
The course of work, solenoid electric valve 2 are closed, and vacuum pump startup vacuumizes vacuum tank, at this moment, flapper valve 1
It opens, hydrogen peroxide is broken off when passing through hydrogen peroxide decomposer 4, and gas is extracted after decomposition, reaches vacuum requirement
Afterwards, solenoid electric valve 2 is opened, and air enters, and at this moment, since vacuum tank is in negative pressure state, enters sky from solenoid electric valve
After gas, 5 both sides of silica gel baffle form pressure differential, and silica gel baffle 5 can be rapidly drawn onto on sealing plane 6 to block to be connected with vacuum tank
Logical port, turns off vacuum pump, and by the sealing of flapper valve 1, vacuum tank just maintains the vacuum state of negative pressure always.
