Abstract
The invention relates to the technical field of medical equipment, in particular to an unqualified medical air reflux device capable of ensuring qualified air output and effectively reducing resource waste and further having the technical advantages of being simple in structure and convenient to use. According to the technical scheme, the unqualified medical air reflux device is characterized by comprising an air inlet pipe fitting, a reflux connection pipe connected with the air inlet pipe fitting, an air outlet connection pipe and an emptying connection pipe, wherein a detection element is arranged on the air inlet pipe fitting, a stop valve I and a pneumatic valve I are arranged on the reflux connection pipe, a stop valve II and a pneumatic valve II are arranged on the air outlet connection pipe, and a manually-operated ball valve is arranged on the emptying connection pipe. The unqualified medical air reflux device can detect air quality, ensure that qualified air flows into an air usage point and make unqualified air flow back to the device for deep treatment, accordingly saves resources, reduces the cost and is simple in structure and convenient to operate.
Description
Technical field
The present invention relates to technical field of medical equipment, be specifically related to a kind of defective medical air reflux.
Background technique
Defective medical air reflux is mainly used in the process gas outlet of medical air compressor group, and this device mainly has the outlet of qualified gas, the backflow of defective gas and manual emptying (for subsequent use) three functions.And medical air compressor group is for the medical gas central station of big-and-middle-sized hospital provides medical air supply source and hospital's part medical equipment to provide aerodynamic force source of the gas.Given this, design one device certainly will be needed to ensure the air quality of the process gas outlet of medical air compressor group, guarantee that acceptable air enters and use gas point, defective air is forbidden to enter uses gas point, and resource is wasted very much in the direct emptying of common defective air, by in-depth process in defective air return to medical air compressor group until qualified just more reasonable.
Summary of the invention
For solving the problems referred to above that prior art exists, the present invention aims to provide a kind of defective medical air reflux, and this reflux should be able to guarantee that up-to-standard air exports, and effectively can reduce the wasting of resources, also there is structure simple, technical characterstic easy to use.
To achieve these goals, the present invention adopts following technological scheme:
Defective medical air reflux, it is characterized in that: comprise air inlet pipe fitting and take over the backflow adapter of its connection, outgoing gas connection tube, emptying, air inlet pipe fitting is provided with Detecting element, backflow adapter is provided with a stop valve and a pneumatic valve, outgoing gas connection tube is provided with No. two stop valves and No. two pneumatic valves, emptying adapter is provided with manual ball valve.
As preferably, described Detecting element comprises pressure transmitter, dew point transmitter and carbon monoxide transmitter.
The invention has the beneficial effects as follows: the present invention can detect air quality, guarantee that acceptable air enters and use gas point, by in-depth process in defective air return to equipment, thus economize on resources, reduce costs, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the invention will be further described, but the present invention is not limited to following examples.
As shown in Figure 1, defective medical air reflux provided by the invention, it is characterized in that: comprise air inlet pipe fitting 1 and with the backflow adapter 2 of its connection, outgoing gas connection tube 7, emptying adapter 8, air inlet pipe fitting 1 is provided with Detecting element, backflow adapter 2 is provided with a stop valve 3 and a pneumatic valve 4, outgoing gas connection tube 7 is provided with No. two stop valves 5 and No. two pneumatic valves 6, emptying adapter 8 is provided with manual ball valve 9.Described Detecting element comprises pressure transmitter 10, dew point transmitter 11 and carbon monoxide transmitter 12.
Air inlet pipe fitting 1 exports with the process gas of medical air compressor group and connects, and outgoing gas connection tube 7 is connected with gas point, and backflow adapter 2 is connected with the suction port of medical air compressor group.A stop valve 3, pneumatic valve 4, No. two stop valves 5, No. two pneumatic valves 6, pressure transmitter 10, dew point transmitter 11 and carbon monoxide transmitters 12 are all connected with the programmable controller (PLC) of medical air compressor group.
Working principle of the present invention is:
1, defective medical air reflux is arranged on the process gas outlet of medical air compressor group, adopt pressure transmitter 10, dew point transmitter 11, carbon monoxide transmitter 12 collecting treatment gas signal, the programmable controller (PLC) being sent to medical air compressor group by 4 ~ 20mA analog signals carries out analyzing, judging that whether air source quality is qualified;
2, when pressure, dew point, carbon monoxide three indexs are all qualified, PLC sends instruction and closes a pneumatic valve 4, open No. two pneumatic valves 6 simultaneously, under the prerequisite that No. two stop valves 5 are opened in advance, acceptable air enters with gas point (being usually introduced into gas holder) through air inlet pipe fitting 1, outgoing gas connection tube 7, No. two stop valves, 5, No. two pneumatic valves 6 (gas open form);
3, when pressure, dew point, carbon monoxide three indexs have one defective time, PLC does not send instruction, now pneumatic valve 4 (gas-tight type) normality is opened, No. two pneumatic valve 6 (gas open form) normalities are closed simultaneously, under the prerequisite that a stop valve 3 is opened in advance, defective air is back to the pipeline in-depth process of medical air compressor group until qualified output through air inlet pipe fitting 1, backflow adapter 2, stop valve, 5, pneumatic valve 4 (gas-tight type);
4, emptying adapter 8 is dedicated air outlet, only has during each pneumatic valve operational failure and just uses, guarantee device security.
Finally, it should be noted that and the invention is not restricted to above embodiment, a lot of distortion can also be had.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
Claims (2)
