Description
Technical field
This utility model relates to a kind of steriliser door sealing and air control unit, particularly a kind ofly is used for that all kinds of dependence compressed gas carry out door sealing, each autocontrol valve is the control device of the steriliser of pneumatic operated valve, belongs to field of pharmaceutical machinery.
Background technology
At present, all kinds of dependence compressed gas carry out door sealing and autocontrol valve is the steriliser of pneumatic operated valve, in the equipment work process, in case fortuitous events such as compressed gas occur stopping, can't guarantee the normal door sealing of equipment, can not guarantee that all operated pneumatic valves are all in the closed position, may cause damage equipment.Along with the development of bio-pharmaceuticals industry, existing mode can not satisfy the security protection demand that improves day by day.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of above-mentioned defective that solved is provided, can guarantees the steriliser door sealing and the air control unit of device security.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of steriliser door sealing and air control unit, comprise steriliser, hermatic door, pneumatic operated valve and compressor inlet pipe, before the steriliser, the back door is connected by pipeline with hermatic door respectively, hermatic door is connected by pipeline with the compressor inlet pipe, be connected with pneumatic operated valve on the pipeline between hermatic door and compressor inlet pipe, it is characterized in that: steriliser Qian Menchu is provided with first pressure transducer, the place, back door is provided with second pressure transducer, the pneumatic operated valve place sets up electric T-shaped valve, electric T-shaped valve one end connects pneumatic operated valve, and an end is connected the compressed gas storage tank after by the pipeline between hermatic door and the compressor inlet pipe.
Described compressor inlet pipe is provided with the 3rd pressure transducer.
Behind compressed gas process filtering pressure reducing valve, the check valve, be divided into three the tunnel, lead to compressed gas storage tank, hermatic door and pneumatic operated valve respectively.The 3rd pressure transducer on the compressor inlet pipe sends warning message when compressed gas pressure is lower than a certain setting value, note checking the compressed gas source situation to remind operator.
In the hermatic door part, the forward and backward door of steriliser is provided with first pressure transducer and second pressure transducer respectively, is used for the detecting gate sealing load.When valve door seal pressure reaches the capping value, think that just door sealing is normal, the behaviour that can sterilize, otherwise will send warning message, remind operator to notice checking whether hermatic door exists unusually.And when carrying out the open and close door operation, when valve door seal pressure reaches preset lower limit, think that just door finds time normally, and otherwise will send warning message, remind operator to notice checking whether hermatic door exists unusually.
In the pneumatic operated valve part, be provided with an electric T-shaped valve.When equipment was in normal operating conditions, electric T-shaped valve was communicated with, and compressed gas is to the normal air feed in valve island.When equipment generation unusual condition (for example pressing emergency stop switch), electric T-shaped valve is obstructed, stops to valve island air feed, and simultaneously remaining compressed gas is discharged in the valve island, guarantees that all pneumatic operated valves cut out, with the assurance device security.
When occurring stopping the supple of gas or steam situation, the 3rd pressure transducer detects compressed gas source pressure and is lower than setting value, sends warning message.Simultaneously, the hermatic door source of the gas transfers to by compressed gas storage tank air feed, guarantees that hermatic door is normal.
The beneficial effect that this utility model had is: steriliser door sealing and air control unit when valve door seal pressure exceeds setting value, can send warning message owing to be provided with first pressure transducer and second pressure transducer, remind operator; Electric T-shaped valve can stop to valve island air feed pneumatic operated valve cutting out when equipment generation unusual condition, has guaranteed device security; When occurring stopping the supple of gas or steam situation, the 3rd pressure transducer detects compressed gas source pressure and is lower than setting value, sends warning message, and the hermatic door source of the gas transfers to by compressed gas storage tank air feed simultaneously, guarantees that hermatic door is normal, has effectively improved the security performance of sterilizing installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, steriliser; 2, hermatic door; 3, pneumatic operated valve; 4, compressor inlet pipe; 5, first pressure transducer; 6, second pressure transducer; 7, electric T-shaped valve; 8, compressed gas storage tank; 9, the 3rd pressure transducer; 10, filtering pressure reducing valve; 11, check valve.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, the forward and backward door of steriliser 1 is connected by pipeline with hermatic door 2 respectively, hermatic door 2 and compressor inlet pipe 4 are connected by pipeline, be connected with pneumatic operated valve 3 on the pipeline between hermatic door 2 and the compressor inlet pipe 4, steriliser 1 Qian Menchu is provided with first pressure transducer 5, the place, back door is provided with second pressure transducer 6, pneumatic operated valve 3 places set up electric T-shaped valve 7, electric T-shaped valve 7 one ends connect pneumatic operated valve 3, one ends and are connected compressed gas storage tank 8 after by the pipeline between hermatic door 2 and the compressor inlet pipe 4; Compressor inlet pipe 4 is provided with the 3rd pressure transducer 9.
