The fire-fighting water tank is communicated with at least one group of gas storage tanks through a gas supply pipe, and the gas supply pipe is provided with at least one gas check valve.
Description
Technical Field
The utility model relates to a medical treatment hyperbaric oxygen cabin field, concretely relates to fire water tank is with automatic minute control system of moisturizing of air water.
Background
Hyperbaric oxygen chambers are specialized medical devices for hyperbaric oxygen therapy. According to the requirements of national regulations and standards, the hyperbaric oxygen chamber must be provided with a special fire-fighting system. At present, a steel fire-fighting water tank is generally adopted and is connected with an air storage tank through an air supply pipe, and the bearing pressure in the fire-fighting water tank is the same as the pressure in the air storage tank. The driving pressure of water spraying is more than or equal to 0.6 MPa. When a fire disaster occurs, a spray switch of the fire-fighting water tank is turned on, and the fire-fighting water is sprayed out in a mist shape (the response time is not more than 3s, and the water spraying strength is not less than 50L/square meter.min).
In daily work, the content of water in compressed air is less than or equal to 575 mg/(N.m) through cultivation according to the requirements of the oxygen cabin safety technology supervision regulation. At present, the fire-fighting water tank installed in domestic oxygen cabin unit is communicated with the gas storage tank, the power of the fire-fighting water is the compressed air of the gas storage tank, and the defects caused easily are as follows:
firstly, compressed air with overlarge humidity in the fire-fighting water tank easily enters the oxygen cabin when pressurized air supply is carried out; some units do not change fire-fighting water all the year round, and the water quality is rotten and peculiar smell, so that compressed air pollution is caused, and personnel in the cabin are damaged.
Secondly, the pressure in the fire fighting water tank can not be kept the same as the pressure in the gas storage tank.
SUMMERY OF THE UTILITY MODEL
The to-be-solved problem of the utility model is to provide an automatic minute control system that pressurizes of air water for fire-fighting water tank effectively forms the air-water isolation, prevents that the too high compressed air of humidity from getting into the oxygen under-deck.
The utility model discloses a realize through following technical scheme:
the utility model provides a fire water tank is with automatic minute control system that mends of air water, includes the fire water tank, the fire water tank has at least a set of gas holder through the air supply pipe intercommunication, be equipped with at least one gas check valve on the air supply pipe.
Furthermore, the number of the air storage tanks is two, one end of the air supply pipe is provided with two air supply branch pipes, and the two air supply branch pipes are respectively and correspondingly communicated with the two groups of air storage tanks; and each gas supply branch pipe is provided with the gas one-way valve.
Furthermore, a manual stop valve is arranged on the air supply pipe close to the fire-fighting water tank.
Furthermore, the top of the fire-fighting water tank is communicated with the air supply pipe.
Compared with the prior art, the utility model the beneficial effect who gains as follows:
1. the arrangement of the gas one-way valve divides the gas in the gas supply pipe into two parts, the air in the gas supply pipeline close to the fire-fighting water tank becomes compressed air with overhigh humidity due to contacting with water, the compressed air with overhigh humidity cannot reversely enter the gas storage tank under the action of the gas one-way valve, so that gas-water isolation is effectively formed, the compressed air with overhigh humidity and pollution is prevented from entering the oxygen chamber when the oxygen chamber is pressurized and supplied with gas each time, and the problems of environmental air pollution and overhigh humidity in the chamber are effectively avoided;
2. when the fire-fighting water tank is in standby use, the highest pressure in the tank is always kept the same as the highest pressure of the gas storage tank; when the fire-fighting water tank is used, compressed air in the air storage tank automatically supplements pressure to gas in the fire-fighting water tank, so that the air pressure in the fire-fighting water tank is always kept the same as the highest pressure in the two groups of air storage tanks (more than or equal to 0.6 MPa);
3. the utility model discloses convenient operation thoroughly solves the problem of traditional fire water pitcher, and application prospect is extensive.
Drawings
FIG. 1 is a schematic structural view of an automatic air-water pressure supplementing and sub-controlling system for a fire-fighting water tank;
in the figure: 1. fire-fighting water tank, 2, air supply pipe, 3, gas holder, 4, gas check valve, 5, manual stop valve.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. The described embodiments are only some embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
In medical treatment hyperbaric oxygen cabin equipment field, two sets of gas holders 3 provide compressed air for a fire control water pitcher 1, in the reentrant oxygen cabin after getting into the gas holder in order to prevent the high compressed air of humidity, the utility model provides a fire control water pitcher is with automatic minute control system of pressurizeing of air water, it is including air supply pipe 2. One end of the air supply pipe 2 is provided with two air supply branch pipes which are respectively communicated with the two groups of air storage tanks 3, and the other end of the air supply pipe 2 is communicated with the top of the fire-fighting water tank 1. The two air supply branch pipes are respectively provided with an air one-way valve 4, so that only compressed air in the air storage tank is allowed to enter the fire-fighting water tank and can not reversely flow. Install manual stop valve 5 on air supply pipe 2, can break off the fire water pitcher, carry out the pipeline and overhaul.
Automatic minute control system of pressurizeing of air water for fire water pitcher, make the gas in the air supply pipe be divided into two through setting up gaseous check valve, thereby the air in the air supply line who is close to the fire water pitcher becomes the compressed air that humidity is too high because of the contact water, the compressed air that humidity is too high can't reverse entering gas holder under the effect of gaseous check valve, effectively form air water isolation, make the pollution when avoiding giving oxygen cabin pressurization air feed at every turn, the compressed air that humidity is too high gets into in the oxygen cabin, the problem of under-deck environmental air pollution and humidity are too high has effectively been stopped. When the fire-fighting water tank is in standby use, the highest pressure in the tank is always kept the same as the highest pressure of the air storage tank; when the fire-fighting water tank is used, compressed air in the air storage tanks automatically supplements pressure to gas in the fire-fighting water tank, so that the air pressure in the fire-fighting water tank is always kept the same as the highest pressure in the two air storage tanks, and the water spraying driving pressure is not less than 0.6 MPa.
