Abstract
The utility model discloses an air leakage detector for braking air bags of an operating table, which comprises an air source, an air pressure regulating valve and a water tank. The height of the water tank is adaptive to that of each braking air bag, the water tank is divided into a plurality of cavities for containing the braking air bags in a multi-line and multi-row manner, the sectional area of each cavity is two times that of each braking air bag, each cavity is filled with water, the plurality of braking air bags with copper core valves facing upwardly are arranged on the cavities in one by one, the air source is connected with an air inlet of the air pressure regulating valve through an air inlet pipeline, and an air outlet of the air pressure regulating valve is connected with each braking air bag arranged in the corresponding cavity through a plurality of air outlet pipelines. The air leakage detector can accurately monitor whether the braking air bags are in air leakage and perform full-detection on the premise of no harm to the braking air bags, so that non-leakage of the braking air bags is guaranteed and a braking device can be ensured to work properly.
Description
Technical field
The utility model relates to a kind of gas leak detection device of operating table brake air sac.
Background technology
Brake gear on the operating table adopts the air brake gear now, and this air brake gear requires highly sensitive, low-carbon (LC) low noise, environment friendly and pollution-free.The vital part of air brake gear is a rubber pneumatic bag.The structure of this rubber pneumatic bag comprises rubber cavity 41 and copper core valve 42 (see figure 1)s, and copper core valve 42 is cast on the inwall of openend of rubber cavity 41.Rubber pneumatic bag requires elastic properties of materials good, and good, the good leak tightness of wearing quality guarantees that air does not have leakage, thereby guarantees that brake gear can be not malfunctioning.Therefore must carry out strict gas leakage to product detects.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of gas leak detection device of operating table brake air sac to be provided, it simple in structure, easy to detect.
The technical scheme that realizes above-mentioned purpose is: a kind of gas leak detection device of operating table brake air sac, comprise source of the gas, an air pressure regulator and a tank, wherein, the height of described tank and the height of described brake air sac are adaptive, this tank is divided into a plurality of cavitys that are used to hold a described brake air sac in the mode of multiple lines and multiple rows, the sectional area of each cavity is the twice of the sectional area of described brake air sac, all fills water in each cavity; A plurality of described brake air sacs are placed in each cavity one by one in its copper core valve mode up; Described source of the gas is connected with the air intake opening of described air pressure regulator by an admission line, and the gas outlet of this air pressure regulator places the brake air sac of described cavity to be connected by many outlet pipes and each.
The technical scheme of the gas leak detection device of operating table brake air sac of the present utility model, adopt the method for external pressurized, the simulation brake gear, the leakproofness of check air bag, whether can accurately monitor brake air sac leaks gas, and can under the situation of brake air sac not being had any injury, examine entirely, thereby can guarantee that brake air sac does not have leakage and guarantees that brake gear can be not malfunctioning.
Description of drawings
Fig. 1 is the sectional view of brake air sac;
Fig. 2 is the structural representation of the gas leak detection device of operating table brake air sac of the present utility model.
Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 2, the gas leak detection device of operating table brake air sac of the present utility model comprises source of the gas 1, an air pressure regulator 2 and a tank 3, wherein,
The height of tank 3 and the height of brake air sac are adaptive, this tank 3 is divided into a plurality of cavitys 30 that are used to hold a brake air sac in the mode of multiple lines and multiple rows, the cross-sectional area of each cavity 30 is twices of the cross-sectional area of brake air sac, all fills water in each cavity 30;
A plurality of brake air sacs are placed in the cavity 30 one by one in its copper core valve mode up;
Source of the gas 1 is connected with the air intake opening of air pressure regulator 2 by an admission line 10, and the gas outlet of this air pressure regulator 2 places the brake air sac of cavity 30 to be connected by many outlet pipes 20 and each.
The effect of each parts is in the gas leak detection device of operating table brake air sac of the present utility model: source of the gas 1 is pressurized air, is used for to the brake air sac pressurising, and brake air sac is expanded; Air pressure regulator 2 both had been used for controlling the switch of break-make between source of the gas 1 and the brake air sac, can regulate the pressure size of the gas that enters in the brake air sac again; Tank 3 is used to hold brake air sac, and it is separated into a plurality of cavitys 30 can detect a plurality of brake air sacs simultaneously, to increase work efficiency.
The principle of work of the gas leak detection device of operating table brake air sac of the present utility model is: source of the gas will (be generally 8 MPas greater than the pressed gas of hydraulic pressure by air pressure regulator 2, this pressure is the twice of the pressure of brake air sac when normally using) charge into brake air sac, brake air sac is expanded, cavity in each tank has limited the expanding volume of brake air sac, guarantee that brake air sac can unrestrictedly not expand, thereby can under the situation of brake air sac not being had any injury, examine entirely, brake air sac seals 30 minutes voluntarily by its copper core valve, observe the water surface in each cavity, because the gaseous tension in the brake air sac is greater than hydraulic pressure, if bubble occurs in the water in the cavity that has, the brake air sac gas leakage in this cavity is described then.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
