Abstract
The utility model discloses an air pressure maintaining device, which comprises a main pipeline, wherein a rapid air-inflation ball valve, a first electric-contact pressure gauge and a one-way valve are sequentially connected onto the main pipeline in an air inlet direction; and a pressure reducing valve is installed at the air inlet end of the rapid air-inflation ball valve and the air outlet end of the first electric-contact pressure gauge through a bypass pipe. The air pressure maintaining device is installed on an air supply pipeline of an alarm system. When the air supply pipeline of the alarm system supplies air, the rapid air-inflation ball valve is opened firstly to enable the alarm system to rapidly inflate air; when the alarm system is about to achieve the air-inflation pressure, the rapid air-inflation ball valve is closed to enable compressed air to only pass through the bypass pipeline and slowly rise to the rated pressure; when the compressed air achieves the pressure, the first electric-contact pressure gauge outputs a stop signal to a control device of the alarm system to stop operating an air compressor of the alarm system, and the air supply pipeline of the alarm system keeps an air pressure maintaining state; and if the air supply pipeline of the alarm system slightly leaks, the first electric-contact pressure gauge outputs a start signal to the control device to start the air compressor to supplement air, and pressure is regulated to the rated pressure.
Description
Technical field
The utility model relates to a kind of device for the pre-alarm system supply air line, particularly relates to a kind of air pressure holding means.
Background technique
Existing air pressure holding means is mainly used on the preact alarm system supply air line, plays the effect that air pressure is kept.The air pressure holding means adopts pressure switch that height air pressure alarm signal and air compressor start stop signal are provided more, but the pressure in the alarm system supply air line is non-adjustable, like this in the situation that the little leakage of generation, pressure reduce, can not send the signal that starts air compressor carrying out tonifying Qi, thereby cause the inconvenience in the use.
The model utility content
In view of this, the air pressure holding means that provides a kind of air pressure adjustable is provided the purpose of this utility model.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of air pressure holding means comprises main line, is connected with fast aeration ball valve, the first pressure gauge with electric contact and one-way valve in turn according to airintake direction on the main line; By by-pass pipe reduction valve is installed at the inlet end of fast aeration ball valve and the outlet side of the first pressure gauge with electric contact.
A kind of air pressure holding means also comprises the second pressure gauge with electric contact, and the second pressure gauge with electric contact is installed between the inlet end of the outlet side of described by-pass pipe and described one-way valve.
A kind of air pressure holding means also comprises the debugging valve, and the debugging valve is installed in the outlet side of described one-way valve.
After adopting said structure, a kind of air pressure holding means of the present utility model has following beneficial effect:
One, this air pressure holding means is installed on the alarm system supply air line, when the alarm system supply air line carries out air feed, open first the fast aeration ball valve, make the alarm system fast aeration, when being about to reach inflation pressure, close the fast aeration ball valve, pressurized air is only passed through from by-pass pipe, slowly rise to rated pressure, when reaching pressure, the first pressure gauge with electric contact output stop signal is to the control gear of alarm system, thus the air compressor of alarm system out of service, and the alarm system supply air line keeps air pressure to keep state; If the air pressure of alarm system supply air line produces little leakage situation, pressure reduces, and then the first pressure gauge with electric contact output actuating signal is carried out tonifying Qi to control gear thereby start air compressor, with adjustable pressure to rated pressure.And the one-way valve that is contained in main line can play unidirectional inflation and prevent the function of press water refluence supply air line.
If the situation of high pressure and low pressure appears in the air pressure of two alarm system supply air lines, then be installed in the second pressure gauge with electric contact output high low pressure alarm signal of one-way valve outlet side, the prompting staff checks.
Description of drawings
Fig. 1 is the structural representation of a kind of air pressure holding means of the present utility model.
Among the figure:
The first pressure gauge with electric contact 3 one-way valves 4
By-pass pipe 5 reduction valve 6
The second pressure gauge with electric contact 7 debugging valves 8
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, a kind of air pressure holding means of the present utility model comprises main line 1, is connected with fast aeration ball valve 2, the first pressure gauge with electric contact 3 and one-way valve 4 in turn according to airintake direction on the main line 1; By by-pass pipe 5 reduction valve 6 is installed at the inlet end of fast aeration ball valve 2 and the outlet side of the first pressure gauge with electric contact 3.
As a preferred embodiment of the present utility model, this device comprises that also the second pressure gauge with electric contact 7, the second pressure gauge with electric contacts 7 are installed between the inlet end of the outlet side of by-pass pipe 5 and one-way valve 4.
As another preferred embodiment of the present utility model, this device also comprises debugging valve 8, and debugging valve 8 is installed in the outlet side of one-way valve 4, can regulate air pressure in the pipeline by debugging valve 8.
This air pressure holding means is installed on the alarm system supply air line, when the alarm system supply air line carries out air feed, open first fast aeration ball valve 2, make the alarm system fast aeration, when being about to reach inflation pressure, close fast aeration ball valve 2, pressurized air is only passed through from by-pass pipe 5, slowly rise to rated pressure, when reaching pressure, the first pressure gauge with electric contact 3 output stop signals are to the control gear of alarm system, thus the air compressor of alarm system out of service, and the alarm system supply air line keeps air pressure to keep state.
If the air pressure of alarm system supply air line produces little leakage situation, pressure reduces, and then the first pressure gauge with electric contact 3 output actuating signals are carried out tonifying Qi to control gear thereby start air compressor, with adjustable pressure to rated pressure.And the one-way valve that is contained in main line can play unidirectional inflation and prevent the function of press water refluence supply air line.
If the situation of high pressure and low pressure appears in the air pressure of alarm system supply air line, then be installed in the second pressure gauge with electric contact 7 output high low pressure alarm signals of one-way valve 4 inlet ends, the prompting staff checks.
Above-described embodiment and accompanying drawing and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
