By adopting the pre-pressurized air chamber device of the utility model, the problem that the pressure of the existing agricultural liquid conveying system is instable due to the highly pressurised liquid pulse is solved, moreover, the pre-pressurized air chamber device of the utility model has the characteristics of simple structure, convenient manufacture, installation and use, and good use effect.
Description
Technical field the utility model relates to a kind of prepressing type air chamber device, belongs to agricultural liquid transporting system product technical field.
The application of the present agricultural liquid transporting system of background technique on agricultural more and more widely; conveying as agricultural water; the conveying of farm pesticide etc.; be not have prepressing type air chamber device in these agricultural liquid transporting systems; such liquid conveying system is because the liquid of being carried exists pulse phenomenon; so produce fluid pressure phenomenon fluctuated through regular meeting, be unfavorable for that the normal liquid of system is carried and irrigation.
Summary of the invention the utility model provides a kind of prepressing type air chamber device of novelty, adopts pre-inflation elastic air chamber membrane technique, realizes the stable purpose of agricultural liquid delivery system pressures.
The technical solution adopted in the utility model is:
A kind of prepressing type air chamber device, in the cavity that air chamber base, air chamber body, air chamber cover are constituted, be provided with an air chamber barrier film with elastic structure, the valve assembly is pressed on the inner side surface of air chamber cover by the opening end of air chamber barrier film pressing plate with the air chamber barrier film, and air chamber barrier film inner chamber communicates with pressure system by the valve inside in the valve assembly.
The air chamber barrier film is a cup-shaped elastic bag structure, one end is the circular arc closed shape, the other end has an opening, the opening installed inside has air chamber barrier film pressing plate, air chamber barrier film pressing plate is pressed in air chamber barrier film edge of opening on the inner side surface of air chamber cover under valve assembly pressuring action, air chamber barrier film inside is hollow-core construction, is used for the preliminary filling pressed gas.
The valve assembly is the bolt shape structure, and there is a valve inside centre, and the valve assembly is twisted in the middle screw of air chamber barrier film pressing plate, air chamber cover.
The utility model beneficial effect is:
Owing to adopted prepressing type air chamber device of the present utility model, solved the system pressure problem of unstable that existing agricultural liquid transporting system is caused owing to the highly pressurised liquid pulse phenomenon, prepressing type air chamber device of the present utility model has: characteristics simple in structure, that manufacturing is easy to install, using effect is good.

Embodiment
As shown in Figure 1.
Prepressing type air chamber device, by: seal ring A1, air chamber base 2, air chamber base plug 3, seal ring B4, air chamber body 5, air chamber barrier film 6, valve assembly 7, air chamber barrier film pressing plate 8, seal ring C9, air chamber cover 10 are formed.
A kind of prepressing type air chamber device, comprise: air chamber base 2, air chamber body 5, air chamber barrier film 6, valve assembly 7, air chamber barrier film pressing plate 8, air chamber cover 10 structures, air chamber base 2 is connected with 5 assemblings of air chamber body, air chamber body 5 is connected with air chamber cover 10 assemblings, air chamber barrier film 6 is arranged in the cavity that air chamber base 2, air chamber body 5, air chamber cover 10 constituted, and valve assembly 7 is pressed on the inboard of air chamber cover 10 by air chamber barrier film pressing plate 8 opening ends with air chamber barrier film 6.
Air chamber barrier film 6 communicates with pressure system by valve assembly 7.
Be provided with air chamber base plug 3 at the two ends of air chamber base 2.
Air chamber base 2 is provided with seal ring A1, is provided with seal ring B4 between air chamber base 2 and air chamber body 5, is provided with seal ring C9 between air chamber body 5 and air chamber cover 10.
Air chamber base 2 is the end cover type structure, and the end cap bottom offers a plurality of liquid through-holes, and a plurality of liquid through-holes communicate with a fluid passage, and fluid passage is connected with the agricultural liquid transporting system.
Air chamber body 5 is columnar structured, and an end is connected with air chamber base 2, and the other end is connected with air chamber cover 10.
Air chamber barrier film 6 is installed in the cavity that air chamber base 2, air chamber body 5, air chamber cover 10 constituted, and air chamber barrier film 6 is a cup-shaped elastic bag structure, and an end is the circular arc closed shape, and the other end has an opening, and inside is hollow-core construction.
Valve assembly 7 is the bolt shape structure, and there is a valve inside centre, and valve assembly 7 is twisted on air chamber cover 10.
Air chamber barrier film pressing plate 8 is circular platy structure, the diameter of air chamber barrier film pressing plate 8 is greater than air chamber barrier film 6 opening end diameters, and air chamber barrier film pressing plate 8 is pressed in air chamber barrier film 6 inboard of air chamber cover 10 under the tension effect of valve assembly 7 from air chamber barrier film 6 opening end inboards.
Assemble by shown in Figure 1, constitute a prepressing type air chamber device, the air chamber base 2 of prepressing type air chamber device is connected with the agricultural liquid transporting system, valve assembly 7 is connected with pressure system,
At first the pressure air of pressure system is charged into air chamber barrier film 6 by valve assembly 7, make the gas that charges into certain working pressure in the air chamber barrier film 6 in advance, pressure system can be carried out certain adjusting and control to the gas pressure in the air chamber barrier film 6, to reach the purpose of stablizing agricultural liquid transporting system liquid working pressure.
When the agricultural liquid transporting system was worked, because the effect of liquid pulse, when the system pressure short time was too high, air chamber barrier film 6 will be by elastic compression, the liquid pressure energy of air chamber barrier film 6 absorption systems, liquid pulse pressure in the reduction system.
Cross when low when the system pressure short time, air chamber barrier film 6 will be amplified by elasticity, and air chamber barrier film 6 discharges pressure energies, the pressure of liquid in the raising system.
Working pressure in the time of so just keeping the work of agricultural liquid transporting system substantially is relatively stable.
