Abstract
The utility model discloses a pneumatic automatic valve which comprises a valve body, a controller, a pressure sensor, an air bag, an air pump and an air storage bottle, wherein the valve body is provided with an inlet and an outlet; the air bag is arranged in the valve body; the air bag is connected with an inflation valve and an air bleeder; the air pump is communicated with the air storage bottle; the air storage bottle is communicated with the air bag through an inflation pipe and the inflation valve; the air pump is connected with the controller; the air bleeder is connected with the controller; and the pressure sensor is arranged on the air storage bottle. The work principle of the pneumatic automatic valve is that the air bag is inflated to expand so as to close a pipeline and is deflated to shrink so as to open the pipeline; and the inflation and deflation can be carried out automatically by the controller according to the setting. In addition, the pneumatic automatic valve can also be used as an overflow valve, and the principle is that when the pressure in the pipeline is larger than the pressure in the air bag, the fluid bursts through the closing of the air bag to reduce the pressure so as to achieve the purpose of limiting the pressure. The pneumatic automatic valve is simple in structure, has good sealing property, low resistance to the fluid and good electric isolation property and is corrosion resistant, beneficial for fertilization and easy to control.
Description
Technical field
The utility model relates to a kind of pneumatic type automatic valve.
Background technique
At present, in clinical medicine and basic medical research, often need control automatically the pipeline inner fluid, control valve commonly used is generally firm structure, and the structure more complicated is not corrosion-resistant, is unfavorable for sterilization, and controls dumbly, and cost is also higher.
Summary of the invention
To above-mentioned existing technology, the utility model provides a kind of pneumatic type automatic valve.
The utility model is realized through following technological scheme:
A kind of pneumatic type automatic valve comprises valve body, controller, pressure transducer, air bag, air pump and air cylinder, and wherein, valve body is provided with outlet and inlet; Air bag is located in the valve body, is connected with gas charging valve and bleed valve on the air bag, and air pump is communicated with air cylinder; Air cylinder is communicated with air bag through gas tube, gas charging valve; Air pump is connected with controller, and bleed valve is connected with controller, and pressure transducer is located on the air cylinder; Be connected with controller, air pump, gas charging valve, bleed valve be the control of controlled device all.
The connecting pipeline of said air pump and air cylinder is provided with one-way valve.
Working principle is: during use, the pneumatic type automatic valve of the utility model is serially connected in the pipeline, blinds off a line through make its expansion to airbag aeration; Make its contraction open pipeline through venting, fill, exit and carry out automatically according to setting: configure pressure through controller in advance, when needs are blinded off a line by controller; Controller is given an order, and air pump is started working and opened gas charging valve simultaneously, makes air bag expansion through inflation; Thereby blind off a line, when pressure transducer detected pressure and reaches setting value, controller was given an order; Air pump quits work, in case air bag is because of inflating too much explosion.When needs were opened pipeline, controller was given an order, and bleed valve is started working, and through venting air bag was shunk, thereby opened pipeline.
In addition; The pneumatic type automatic valve of the utility model can also be worked as relief valve (safety valve) and used; Its principle is: when the pressure in the pipeline during greater than the pressure in the air bag (pressure in the air bag can be controlled according to the setting of pressure transducer); Fluid is washed the sealing of air bag open, and pressure is reduced, and reaches the purpose of restriction pressure.
The utility model is simple in structure, good seal performance, and the resistance of convection cell little (being particularly suitable in low pressure line, using), corrosion-resistant; Help sterilization, electrical isolation performance good (this is particularly important in clinical use), control is easily.In addition, because of valve part fabricating cost is low, can make disposable products.The pneumatic type automatic valve of the utility model can be used for clinical medicine and fundamental research is controlled the pipeline inner fluid automatically.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of pneumatic type automatic valve comprises valve body 1, controller 6, pressure transducer 7, air bag 2, air pump 8 and air cylinder 9, and like Fig. 1, shown in Figure 2, wherein, valve body 1 is provided with outlet 4 and inlet 3; Air bag 2 is located in the valve body 1, is connected with gas charging valve 10 and bleed valve 11 on the air bag 2, and air pump 8 is communicated with air cylinder 9; Air cylinder 9 is communicated with air bag 2 through gas tube 5, gas charging valve 10; Air pump 8 is connected with controller 6, and bleed valve 11 is connected with controller 6, and pressure transducer 7 is located on the air cylinder 9; Be connected the control of air pump 8, gas charging valve 10, all controlled device 6 of bleed valve 11 with controller 6.
Said air pump 8 is provided with one-way valve 12 with the connecting pipeline of air cylinder 9.
Working principle is: during use, the pneumatic type automatic valve is serially connected in the pipeline, through to air bag 2 inflations its expansion being blinded off a line; Make its contraction open pipeline through venting, fill, exit and carry out automatically according to setting: configure pressure through controller 6 in advance, when needs are blinded off a line by controller 6; Controller 6 is given an order, and air pump 8 is started working, and opens gas charging valve simultaneously; Make air bag 2 expansion through inflation, thereby blind off a line, when pressure transducer 7 detects pressure and reaches setting value; Controller 6 is given an order, and air pump 8 quits work, in case air bag 2 is because of inflating too much explosion.When needs were opened pipeline, controller 6 was given an order, and bleed valve 11 is started working, and through venting air bag 2 was shunk, thereby opened pipeline.
In addition; The pneumatic type automatic valve of the utility model can also be worked as relief valve (safety valve) and used; Its principle is: when the pressure in the pipeline during greater than the pressure in the air bag 2 (pressure in the air bag 2 can be controlled according to the setting of pressure transducer 7); Fluid is washed the sealing of air bag 2 open, and pressure is reduced, and reaches the purpose of restriction pressure.
The pneumatic type automatic valve of the utility model can be used for clinical medicine and basic medical research is controlled the pipeline inner fluid automatically.
