Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Fig. 1 is the structural representation of mechanical type negative pressure protector of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is a kind of mechanical type negative pressure protector, is described further working mechanism of the present utility model below in conjunction with accompanying drawing.
Mechanical type negative pressure protector is provided with the first cylindrical shell 1, the second cylindrical shell 2 be arranged in the first cylindrical shell 1, three cylindrical shell 3 of back-off on the second cylindrical shell 2, be fixed on flange part 18 above the first cylindrical shell 1.
The bottom 12 of the second cylindrical shell 2 stretches out and to link together with the sidewall of the first cylindrical shell 1, first cylindrical shell 1 is divided into the first reception room 111, second reception room 112, first cylindrical shell 1 is provided with by the outward extending blind flange 4 of the first cylindrical shell 1 top sidewall, to seal bottom the first cylindrical shell 1 and outward extending base flange 13, the drainpipe 15 be communicated with the first reception room 111, be positioned at two short tubes 9 be connected to outside the first cylindrical shell 1 on first cylindrical shell 1 sidewall, 11 and be connected to two short tubes 9, between 11 and with two short tubes 9, 11 transparent pipes 10 be communicated with, two short tubes 9, 11 perpendicular to the first cylindrical shell 1, transparent pipe 10 is parallel to the first cylindrical shell 1, drainpipe 15 is provided with a valve 16, the sidewall of the second reception room 112 is provided with some passages 14, base flange 13 is for solid mechanical formula negative pressure protector.
The pipeline 7 that flange part 18 is provided with upper flange 8, lower flange 5 and is connected between upper flange 8 and lower flange 5, upper flange 8 is fixed on gas generator (not shown), lower flange 5 is provided with the water inlet pipe 6 of band sealing plug (not shown), seals the first cylindrical shell 1 together with lower flange 5 is bolted on blind flange 4.
By water inlet pipe 6 to water filling in the first reception room 111 of the first cylindrical shell 1, and observe the water surface 17 in the first cylindrical shell 1 by transparent pipe 10, when the gas pressure in gas generator is less than the pressure in the first reception room 111, 3rd cylindrical shell 3 will be picked up, gas in air just enters the second cylindrical shell 2 by the passage 14 of the second reception room 112, the first reception room 111 is entered along the gap between the second cylindrical shell 2 and the 3rd cylindrical shell 3, and overflow from the water surface 17 the first reception room 111, add in time in gas generator finally by pipeline 7, prevent the negative pressure in gas generator from producing.
When the gas pressure in gas generator is greater than the pressure in the first reception room 111; the water surface 17 in first cylindrical shell 1 declines; the water surface between second cylindrical shell 2 and the 3rd cylindrical shell 3 raises; the differential water pressures that between second cylindrical shell 2 and the 3rd cylindrical shell 3, water and the first cylindrical shell 1 are formed equals the pressure of gas in gas generator; by water inlet pipe 4 to water filling in the first cylindrical shell 1; regulate the position of the water surface 17 in the first cylindrical shell 1; mechanical type negative pressure protector floor space in the utility model is little; use easy to operate, regulate sensitive.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
