Abstract
The invention discloses a door sealing system of a high-temperature sterilization cabinet. The door sealing system comprises a communicating pipeline, an air compression device, a one-way valve, a pneumatic control one-way valve and a door sealing four-way safety valve, wherein the gas output terminal of the air compression device is communicated with one end of the pneumatic control one-way valve and the first opening of the door sealing safety valve via the pipelines at the same time; the second opening of the door sealing safety valve is communicated with gas in the high-temperature sterilization cabinet; the other end of the pneumatic control one-way valve is connected with one gas inlet of the communicating pipeline; the other gas inlet of the communicating pipeline is connected with one end of the one-way valve; the other end of the one-way valve is communicated with the third opening of the door sealing four-way safety valve; the fourth opening of the door sealing four-way safety valve is communicated with the gas in the high-temperature sterilization cabinet; and two gas outlets of the communicating pipeline are respectively communicated with two grooves in an accommodation seal ring on a door panel of the sterilization cabinet. The door sealing system has the beneficial effects that pressure compensation is realized by means of the gas in the cabinet in the case of insufficient compressed air pressure so as to eliminate various potential safety hazards caused by insufficient seal.
Description
Technical field
The invention belongs to sterilizing cabinet technical field of sealing technology, relate in particular to the door sealing system of high-temperature sterilization cabinet.
Background technology
High-temperature sterilization cabinet is a kind of cabinet that utilizes steam to carry out sterilizing, and it is widely used in pharmaceutical field.High-temperature sterilization cabinet in normal operation, need to seal with cabinet intracorporeal space the door of sterilizing cabinet, and for this reason, prior art provides the door sealing system of a high-temperature sterilization cabinet.
Usually, the door-plate of high-temperature sterilization cabinet is provided with two grooves near door-plate top and bottom respectively, the accommodating sealing ring of difference in two grooves, as shown in Figure 1, the door sealing system of the high-temperature sterilization cabinet that prior art provides comprises a connecting pipe road, this connecting pipeline comprises an air inlet and two gas outlets, and air inlet connects the gas output end of pressing empty device by a valve, and two gas outlets communicate with two grooves respectively.In use, open valve, make to press the compressed air of empty device output to enter connecting pipeline, thereby sealing ring is pressed on to door-plate inner surface and plays sealing function.
But due in process of production, produce High Temperature High Pressure in high-temperature sterilization cabinet, once extraneous compressed air stops, sealing cannot ensure, has serious potential safety hazard.
Summary of the invention
The object of the embodiment of the present invention is to provide the door sealing system of a high-temperature sterilization cabinet, cannot ensure sealing to solve the door sealing system of existing high-temperature sterilization cabinet, has the problem of serious potential safety hazard.
The embodiment of the present invention is achieved in that a kind of door sealing system of high-temperature sterilization cabinet, and described system comprises: connecting pipeline, press empty device, check valve, gas control check valve, door sealing insurance cross valve; Press the gas output end of empty device by one end of pipeline connection gas control check valve, the gas output end of the empty device of described pressure is simultaneously by the first port of door sealing easing valve described in pipeline connection, and the second port of described door sealing easing valve is communicated with the interior gas of cabinet of high-temperature sterilization cabinet; The other end of described gas control check valve connects an air inlet of pipeline, another air inlet of connecting pipeline connects one end of check valve, the other end of check valve is communicated with the third connectivity mouth of described door sealing insurance cross valve, and the four-way mouth of described door sealing insurance cross valve is communicated with the interior gas of cabinet of high-temperature sterilization cabinet; Two gas outlets of described connecting pipeline communicate with two grooves of accommodating sealing ring on sterilizing cabinet door-plate respectively.
Outside the approach that the door sealing system of high-temperature sterilization cabinet provided by the invention seals at the existing compressed air of reservation, utilize gas in cabinet to carry out pressure compensation to compressed air pressure deficiency or situation about making zero, play the effect to the dual-seal of sterilizing cabinet door-plate, eliminated the not enough existing various potential safety hazards of sealing.
Brief description of the drawings
Fig. 1 is the structure chart of the door sealing system of the high-temperature sterilization cabinet that provides of prior art;
Fig. 2 is the structure chart of the door sealing system of high-temperature sterilization cabinet provided by the invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 2, the door sealing system of high-temperature sterilization cabinet of the present invention comprises: connecting pipeline 5, press empty device 1, gas control check valve 2, check valve 3, door sealing insurance cross valve 4; Wherein, press the gas output end of empty device 1 by one end of pipeline connection gas control check valve 2, press the gas output end of empty device 1 simultaneously by the first port B of pipeline connection door sealing easing valve 4, the second port D of door sealing easing valve 4 is communicated with the interior gas of cabinet of high-temperature sterilization cabinet; The other end of gas control check valve 2 connects an air inlet of pipeline 5, another air inlet of connecting pipeline 5 connects one end of check valve 3, the third connectivity mouth A of the other end communicating door sealing insurance cross valve 4 of check valve 3, the four-way mouth C of door sealing insurance cross valve 4 is communicated with the interior gas of cabinet of high-temperature sterilization cabinet; Two gas outlets of connecting pipeline 5 communicate with two grooves of accommodating sealing ring on sterilizing cabinet door-plate respectively.
The door sealing system of this high-temperature sterilization cabinet is in the time of normal work, if the compressed air pressure of pressing empty device 1 to export is normal, gas control check valve 2 is in opening, check valve 3 insures cross valve 4 all in closed condition with door sealing, thereby in the cabinet of high-temperature sterilization cabinet, gas is not connected with the extraneous compressed air entering, the compressed air that the external world enters is directly entered connecting pipeline 5 and sealing ring is pressed in to door-plate by gas control check valve 2, usually, now the cabinet internal gas pressure of high-temperature sterilization cabinet is 0.2 to 0.3MPa, and the compression gas-pressure that the external world enters is 0.6-0.8MPa; In the time pressing empty device 1 to occur occurring that extremely or due to other reason extraneous compressed air pressure reduces or makes zero; gas control check valve 2 is closed; check valve 3 and door sealing insurance cross valve 4 are opened; the interior gas of cabinet of high-temperature sterilization cabinet insures cross valve 4 by door sealing in turn and check valve 3 enters connecting pipeline 5; thereby realize the effect of the door-plate sealing to sterilizing cabinet, play the function of dual-seal protection.Check valve 3 is wherein made mistakes and is caused compressed air to enter gas in cabinet and arrange for further anti-locking system.
Outside the approach that the door sealing system of high-temperature sterilization cabinet provided by the invention seals at the existing compressed air of reservation, utilize gas in cabinet to carry out pressure compensation to compressed air pressure deficiency or situation about making zero, play the effect to the dual-seal of sterilizing cabinet door-plate, eliminated the not enough existing various potential safety hazards of sealing.
