Abstract
The utility model discloses an evacuating device of steam sterilization cabinet preventing overheated air from entering vacuum pump, which comprises a vacuum pump and an exhaust pipe extending into the inner cavity of the steam sterilization cabinet; the pipe end of the exhaust pipe is connected with an exhaust valve; the exhaust valve and the vacuum pump are connected by a condenser. In the utility model, an evacuating pipe between the exhaust pipe and the vacuum pump is prolonged, and is set into a by-pass structure; moreover, cooling pipes are sleeved on each straight section of the evacuating pipe; the air in the sterilization chamber is cooled when passing through the evacuating pipe, thus effectively preventing the overheated air from being pumped into the vacuum pump and leading a gland bush in the vacuum pump from being aged early, thus ensuring the normal use of the vacuum pump.
Description
Technical field
This utility model relates to vacuum extractor, refers more particularly to the vacuum extractor of vacuum sterilizer.
Background technology
The vacuum extractor of traditional vacuum sterilizer, its structure comprises: vacuum pump and the exhaustor that stretches into vacuum sterilizer inner chamber (sterile chamber), the pipe end of exhaustor is provided with air bleeding valve, and air bleeding valve links to each other with vacuum pump by short vacuum-pumping tube.In practical work process, all be after usually with the discharge of steam in the vacuum sterilizer, with regard to directly opening vacuum pump the sterile chamber is carried out evacuation.At this moment, gas temperature in the sterile chamber is also than higher, and the sealing gasket in the vacuum pump all is to be made by the common material of non-refractory usually, when high-temperature gas directly is drawn into vacuum pump, the water cycle of depending merely on vacuum pump cools off, and the high-temperature gas that is drawn into vacuum pump can't be reduced to below the temperature that described sealing gasket can bear.Will cause the sealing gasket premature aging like this, shorten the service life of vacuum pump.
The utility model content
A technical problem to be solved in the utility model is: provide a kind of overheated gas that prevents to enter the vacuum extractor of the vacuum sterilizer of vacuum pump.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the vacuum extractor of vacuum sterilizer, comprise: vacuum pump and stretch into the exhaustor of vacuum sterilizer inner chamber, the pipe end of exhaustor links to each other with air bleeding valve, links to each other by cooler between described air bleeding valve and the vacuum pump.
The concrete structure of described cooler comprises: the vacuum-pumping tube that connects air bleeding valve and vacuum pump, this vacuum-pumping tube is the winding type structure, comprise a plurality of straightways and corresponding changeover portion, be set with cooling tube on each straightway of vacuum-pumping tube, the circuitous serial connection of all cooling tubes is communicated with.
The beneficial effects of the utility model are: this utility model will be by connecting the vacuum-pumping tube lengthening of air bleeding valve and vacuum pump, and be arranged to the winding type structure, and on each straightway of vacuum-pumping tube, be set with cooling tube, gas in the sterile chamber is cooled through vacuum-pumping tube the time, prevented that effectively overheated gas is drawn into vacuum pump, make that the sealing gasket in the vacuum pump can premature aging, guaranteed the normal use of vacuum pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, sterile chamber, 2, exhaustor, 3, air bleeding valve, 4, vacuum-pumping tube, 5, cooling tube, 6, vacuum pump.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, the vacuum extractor of vacuum sterilizer described in the utility model, comprise: vacuum pump 6 and stretch into the exhaustor 2 that the vacuum sterilizer inner chamber is sterile chamber 1, the pipe end of exhaustor 2 is provided with air bleeding valve 3, be provided with cooler between air bleeding valve 3 and the vacuum pump 6, its concrete structure comprises: the vacuum-pumping tube 4 that connects air bleeding valve 3 and vacuum pump 6, this vacuum-pumping tube 4 is the winding type structure, comprise a plurality of straightways and corresponding changeover portion, be set with cooling tube 5 on each straightway of vacuum-pumping tube 4, all cooling tube 5 circuitous serial connections are communicated with.Like this, just between the inwall of the outer wall of vacuum-pumping tube 4 and cooling tube 5, form the cooling duct.During practical application, the water inlet of cooling duct and outlet are connected with the water inlet and the outlet of the cooling water channel of vacuum pump 6 respectively.
