Abstract
The utility model relates to a combination valve for a gas cylinder assembly of an emergency escape respiration apparatus, which comprises a first valve body and a second valve body which are in seal connection. A switch rod and a medium pressure safety valve are arranged in the first valve body, the rear end of the switch rod is provided with an emergency starting pulling cover, a pair of O-shaped rings for sealing a venting hole of the first valve body is arranged at the front end of the switch rod, and the venting hole of the first valve body is connected with a rapid connector. An alarm whistle and a high pressure safety valve are arranged on the second valve body, and a venting pipe is arranged on a venting opening at the front end of the second valve body. The combination valve has the functions of opening and closing a gas source and decompressing and outputting high pressure gas. A cylinder valve and a decompressor are integrated, the structure is simplified, the cost is reduced, and the medium pressure safety valve and the low pressure safety valve are added. The problem that a traditional cylinder valve structure adopts a rotary hand wheel to open the gas source is solved, the combination valve opens the gas source through a drawing pin, and when a user wears the combination valve, the drawing pin can be automatically pulled to open the gas source. The combination valve is connected with a gas supply pipe through the rapid connector, and connection can be finished only by inserting, thereby being fast and convenient.
Description
Technical field
The utility model relates to a kind of gas cylinder group of Emergency Escape Breathing Device and uses combination brake switch and proporting.
Background technique
Bottle valve on the existing pressurized container and decompressor divide often and to be arranged, and cost is higher and trouble is installed.Existing bottle valve structure often adopts the mode of rotation hand wheel to open source of the gas, opens effort.In addition, existing bottle valve does not have the function of low pressure alarming, can not remind user's pressurized air to be about to use up, and has brought potential safety hazard to the user.
The model utility content
The technical problem that the utility model will solve provides a kind of gas cylinder group of Emergency Escape Breathing Device of simple in structure, the function of installing and using more convenient and the low pressure alarming that has and uses combination brake switch and proporting.
In order to solve the problems of the technologies described above, the utility model provides a kind of gas cylinder group of Emergency Escape Breathing Device to use combination brake switch and proporting, comprising: first valve body that is tightly connected each other and second valve body; Be provided with switch lever and middle pressure safety valve in first valve body, the rear end of this switch lever is provided with emergency starting and draws lid, and the front end of this switch lever is provided with the pair of O shape circle of the vent that is used for shutoff first valve body, and the vent of this first valve body links to each other with a rapid pipe joint; Second valve body is provided with the warning whistle and high-pressure safety valve; The front end air outlet of second valve body is provided with breathing pipe.
Further, also be provided with inflation inlet and pressure gauge on said second valve body, be sealed with plug on the inflation inlet.
Further, be provided with the gas that is used in the gas cylinder group in said first valve body and gas imported the piston of the said warning whistle to report to the police when under-voltage.
Further, the rear end of said switch lever is provided with the pin that draws that is used for fixing this switch lever.
The technique scheme of the utility model is compared existing technology and had the following advantages: the gas cylinder group of the Emergency Escape Breathing Device of (1) the utility model is used combination brake switch and proporting, plays the effect of open and close to source of the gas, high pressure air reducing, output.It has broken conventional pressure container bottle head valve and the theory that decompressor separates design, and bottle valve and decompressor are combined together, and simplified structure reduces cost.Press the safety valve and the low pressure alarming whistle in setting up.The bottle valve structure that breaks traditions rotation hand wheel is opened source of the gas, adopts and draws pin, when user's wearable product, can draw back pin automatically and open source of the gas.Be connected employing rapid pipe joint with air supply pipe, one slotting getting final product is convenient and swift during connection.(2) working principle: when dormant state, draw pin to be fixed on the aperture position of switch lever, this moment, the O shape circle of switch lever front end got in the vent of first valve body, was in the source of the gas state of closing.During use, saidly draw pin to pass through one to start band and link to each other, when the user takes out head-shield with head-shield; Can will draw pin to pull out; Switch lever is motion backward under the effect of gas pressure, and the O shape circle of switch lever front end can shift out the vent of first valve body, and source of the gas is in opening state.Gas enters in the head-shield through rapid pipe joint, breathing pipe, supplies human body respiration.When decompression was broken down, delivery pressure can increase.When being increased to certain limit, middle pressure safety valve can be opened release pressure automatically, plays the effect of protection combination brake switch and proporting.The user wears this combination brake switch and proporting when escape, when gas when using up, the O shape circle of piston nose can move to the notch place of first valve body.The aperture of gas this moment through the notch place enters into the warning post and puts, and blows the warning whistle and sends chimes of doom, reminds user's gas to be about to use up.
