Description
Technical field
The utility model relates to a kind of medical facility, relates in particular to a kind of its waste gas of anesthesia with Anesthesia machine discharging in the operating room that utilizes and is discharged into outdoor toxic emission valve.
Background technique
The working principle of exhaust emission system product is directly directly to be discharged in the discharge pipe with the operating room Anesthesia machine with by the waste gas that operation patients is breathed out by the vacuum suction source mostly both at home and abroad at present, and its system complex, manufacture cost height, attraction negative pressure fluctuate bigger and wayward.
Summary of the invention
The purpose of this utility model provides a kind of toxic emission valve, and it can overcome defective of the prior art, produce to attract negative regulation and reliable.
For achieving the above object, the utility model is taked following design proposal:
A kind of toxic emission valve includes:
Offer the main valve body of air collecting chamber in one, the air collecting chamber of main valve body is three-port structure, and the one side has the inlet that is used to receive waste gas, and this ingress is provided with an anti-pollution valve; Opposite side is established balanced component; Another side is offered negative cavity;
One has the jet type vacuum pump of suction port, jetburner and jet driving device, and the intakeport of this jet type vacuum pump side and the negative cavity of main valve body connect.
Described balanced component by aeration valve, negative pressure experience diaphragm, the arm spring sheet is formed, the aeration valve is positioned at the passage port that main valve body air collecting chamber and ambient air join, negative pressure is experienced diaphragm and is positioned at main valve body air collecting chamber inside front, and negative pressure is experienced the distortion may command regulations and parameters spring sheet action of diaphragm to open and close the aeration valve.
The inlet of the reception waste gas of described main valve body air collecting chamber connects the Anesthesia machine floss hole.
The suction port of described jet type vacuum pump connects source of compressed air.
Above-mentioned jet type vacuum pump can adopt existing the type equipment, and it is simple in structure, and reliable operation is convenient to operation, without any need for prime mover, can directly be used for pumping poisonous or etchant gas.
The utility model toxic emission valve is mainly used in and cooperates operating room to use, and the waste gas of anesthesia that Anesthesia machine in the operating room is discharged directly is discharged into outdoor.This system and device produces negative pressure by jet driving device, by the balanced component steady pressure.
The utility model has the advantages that: system architecture is simplified, cost is low; Stable and reliable working performance.
Description of drawings
Fig. 1 is the utility model toxic emission valve arrangement schematic representation (main pseudosection).
Fig. 2 is the utility model toxic emission valve arrangement schematic representation (top plan view).
Fig. 3 is a toxic emission valve main valve body balanced component structural representation
Below in conjunction with drawings and the specific embodiments the utility model is described in further details:
Embodiment
Consult Fig. 1, shown in Figure 2, the utility model toxic emission valve is constituted by main valve body 1 and jet type vacuum pump 2.
Offer air collecting chamber 11 in the described main valve body 1, air collecting chamber 11 is three-port structure, and the one side has the inlet 12 that is used to receive waste gas, and this ingress is provided with an anti-pollution valve 13; Opposite side is established balanced component (aeration valve 14, negative pressure are experienced diaphragm 15, arm spring sheet 16).
The utility model toxic emission valve be mainly used in waste gas of anesthesia with Anesthesia machine discharging in the operating room be discharged into outdoor, so the inlet 12 of above-mentioned reception waste gas should be directly or is connect the floss hole of Anesthesia machine by pipeline.
Described jet type vacuum pump 2 has the intakeport 23 of suction port 21, jetburner 22 and side, built-in jet driver element device and jet units device.Suction port 21 connects jet driver element device; The delivery nozzle of jet units device directly has jetburner 22, and this jetburner 22 can connect discharge pipe until outdoor; The intakeport 23 of this jet type vacuum pump side connects with the air collecting chamber of main valve body 11.The suction port external compressed air source of described jet type vacuum pump.
Referring to Fig. 3, described balanced component by aeration valve 14, negative pressure experience diaphragm 15, arm spring sheet 16 is formed, the aeration valve is made up of parts such as valve seat, spring, housings.At the air collecting chamber internal upper part one negative pressure is installed and experiences diaphragm 15, negative pressure surpasses setting value in air collecting chamber, negative pressure is experienced diaphragm and is inhaled downwards and the generation distortion by negative pressure, compressing arm spring sheet moves downward, thereby open the aeration valve, air enters the balancing gas collecting cavity pressure from the aeration valve, when pressure is elevated to certain value, negative pressure is experienced diaphragm and is resetted, and the aeration valve cuts out.
The working principle of the utility model toxic emission valve: feed the drive compression air source from suction port 21, air-flow produces negative pressure through the jet type vacuum pump at air collecting chamber 11 places, (negative pressure that produces of large stream is big more more to drive air pressure) will suck air collecting chamber 11 and discharge by discharge pipe together by jetburner 22 and drive compression air from the waste gas of anesthesia that the Anesthesia machine floss hole sucks.During work, when negative pressure is excessive in the air collecting chamber 11, can experiences diaphragm 15 distortion by negative pressure and open aeration valve 14, suck ambient air, make air collecting chamber 11 internal pressures keep stable to reduce the pressure in the air collecting chamber 11 by arm spring sheet 16.
