Description
Technical field
This utility model relates to a kind of steriliser door automatic safe sealing ensuring equipment, belongs to field of pharmaceutical machinery.
Background technology
At present, the application of HTHP moist heat sterilizer more and more widely, quantity is increasing especially; Wherein most door sealing system adopts compressed gas sealing joint strip system, comprises steriliser, and door is installed on the steriliser; The steriliser of answering the door is provided with the door sealing groove, in the door sealing groove, is provided with sealing joint strip, steriliser is provided with the compressed gas pipeline; Compression gas pipe wired-AND gate seal groove is connected, and the valve door seal pressure detector is installed on the compressed gas pipeline.During use,, make compressed gas access door seal groove, thereby give sealing joint strip a valve door seal pressure, reach the purpose of effective sealing between door and the steriliser to the extruding of door direction through giving compressed gas pipeline air feed.In above-mentioned work process, if during the hypotony on the compressed gas pipeline, pressure in the chamber will appear greater than valve door seal pressure, the high-temperature high-pressure medium steriliser upper chamber in is very easily revealed, thus the generation security incident.
The utility model content
According to above deficiency of the prior art, the technical problem that this utility model will solve is: a kind of steriliser door automatic safe sealing ensuring equipment is provided, guarantees valve door seal pressure more than or equal to cavity indoor pressure, prevent that the high-temperature high-pressure medium in the chamber from revealing.
The described steriliser door of this utility model automatic safe sealing ensuring equipment comprises steriliser, and door is installed on the steriliser; The steriliser of answering the door is provided with the door sealing groove, in the door sealing groove, is provided with sealing joint strip, steriliser is provided with the compressed gas pipeline; Compression gas pipe wired-AND gate seal groove is connected; The valve door seal pressure detector is installed on the compressed gas pipeline, it is characterized in that: steriliser is provided with safe connecting pipeline, and safe connecting pipeline one end and door sealing groove are connected; Chamber in the other end and the steriliser is connected, and on the safety connecting pipeline, is equipped with and often drives pneumatic operated valve.
Under the normality, often open pneumatic operated valve valve island and get electricly, pneumatic operated valve is in closed condition always.During use, cross when low, often open the outage of pneumatic operated valve valve island when the valve door seal pressure detector detected pressures on the compressed gas pipeline; Thereby make and often drive pneumatic operated valve and be in open mode; Under the connection effect of safety connecting pipeline, make pressure and valve door seal pressure in the chamber be in poised state, prevented effectively because of the pressure in the chamber greater than valve door seal pressure; High-temperature high-pressure medium in the steriliser upper chamber is revealed, avoided the generation of security incident.
On the said safe connecting pipeline check valve is installed, check valve is installed in the door sealing groove and often opens between the pneumatic operated valve.
Check valve is set, and both convenient for maintaining was often driven pneumatic operated valve, can prevent that again the compressed gas in the valve door seal pressure from flowing in chamber.When running into power failure, often open the outage of pneumatic operated valve valve island, often drive pneumatic operated valve and also can be in open mode; If this moment, valve door seal pressure was greater than interior chamber pressure; Check valve will seal, and what seal remains compressed gas, if valve door seal pressure is during smaller or equal to interior chamber pressure; Check valve will be opened, and interior chamber pressure will replace compressed gas to realize door sealing.
Said check valve is provided with the hand-operated valve parallelly connected with often driving pneumatic operated valve with safe connecting pipeline between the chamber.
Hand-operated valve is set, has further facilitated the maintenance of often driving pneumatic operated valve.Cross when low when the valve door seal pressure detector detected pressures on the compressed gas pipeline, when often driving pneumatic operated valve and breaking down again, can also come pressure and valve door seal pressure in the balance chamber through the control hand-operated valve.
Compared with prior art, the utlity model has following beneficial effect:
Through this utility model, it is simple in structure, and is easy to operate.During pressure in valve door seal pressure is lower than chamber; Can often drive pneumatic operated valve or hand-operated valve comes pressure and valve door seal pressure in the balance chamber through controlling; Prevented effectively because of the pressure in the chamber greater than valve door seal pressure; High-temperature high-pressure medium in the sterilizer chamber is revealed, avoided the generation of security incident.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the local structure for amplifying sketch map at A place among Fig. 1;
Among the figure: 1, compressed gas pipeline 2, valve door seal pressure detector 3, door sealing groove 4, sealing joint strip 5, door 6, steriliser 7, safe connecting pipeline 8, chamber 9, check valve 10, often drive pneumatic operated valve 11, hand-operated valve.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done and to be further described:
Like Fig. 1, shown in Figure 2, steriliser door automatic safe sealing ensuring equipment comprises steriliser 6; Door 5 is installed on the steriliser 6,5 sterilisers 6 of answering the door are provided with door sealing groove 3, in door sealing groove 3, be provided with sealing joint strip 4; Steriliser 6 is provided with compressed gas pipeline 1, and compressed gas pipeline 1 is connected with door sealing groove 3, and valve door seal pressure detector 2 is installed on compressed gas pipeline 1; Steriliser 6 is provided with safe connecting pipeline 7; Safe connecting pipeline 7 one ends and door sealing groove 3 are connected, and the chamber 8 in the other end and the steriliser 6 is connected, and on safety connecting pipeline 7, is equipped with and often opens pneumatic operated valve 10 and check valve 9; Check valve 9 is installed in door sealing groove 3 and often opens between the pneumatic operated valve 10, and check valve 9 and safe connecting pipeline 7 between the chamber 8 are provided with the hand-operated valve 11 parallelly connected with often driving pneumatic operated valve 10.
