Abstract
The utility model discloses a pneumatic valve, which comprises a valve body. The middle part of the valve body is provided with a fluid passage; two ends of the fluid passage are respectively an inlet and an outlet; a rubber hose is arranged in the fluid passage; two ends of the rubber hose are hermetically connected with the inner wall of the valve body; the side wall of the valve body is provided with an air vent and is externally connected with an air inlet pipe and an air exhausting pipe respectively; the air inlet pipe and the air exhausting pipe are internally provided with a control valve respectively; the air inlet pipe is externally connected with an air supply; and a gap is arranged and a closed air bag is formed between the valve body and the rubber hose. The pneumatic valve is simple and compact in structure, large in sealing area and long in service life, is convenient to operate and convenient to mount and repair, and has quite good practical value.
Description
Technical field
The utility model relates to a kind of pneumatic valve.
Background technique
Valve is widely used in the industrial and agricultural production.Existing Air control valve mainly contains compositions such as pneumatic actuator, pilot line and valve.Its actuator mainly is that the to-and-fro motion through cylinder drives butterfly plate or ball valve core or other corresponding mechanism and carries out rigidity and open and close operation, make the sealing position easily because of friction damages, and complex structure causes changing difficulty of Sealing.
The model utility content
The purpose of the utility model provides a kind of pneumatic valve, solves the problem that existing pneumatic valve structural rigidity opens and closes.
The technological scheme of the utility model is following:
A kind of pneumatic valve includes valve body, and the middle part of said valve body has the fluid passage; The two ends of said fluid passage are respectively inlet/outlet; It is characterized in that: be provided with rubber pipe in the described fluid passage, the two ends of said rubber pipe are connected with the inner wall sealing of valve body, said valve body sidewall be provided with ventilating hole and respectively external suction tude and outlet pipe; Be separately installed with control valve in described suction tude and the outlet pipe, the external source of the gas of described suction tude; Have the gap and form airtight air bag between described valve body and the described rubber pipe.
Described pneumatic valve is characterized in that: on described suction tude or the outlet pipe pressure gauge is installed.
The beneficial effect of the utility model:
The utility model is simple in structure, compact, and sealing area is big, adopts the actuator of sebific duct as valve; Distending or contraction through air pressure control sebific duct realize the keying of valve, thereby make valve realize flexible the keying, the situation that the easy friction of actuator damages when not existing rigidity to open and close; Go back the flow that the distending amount of can regulate sebific duct is come regulating valve through regulating the air pressure size, easy to operate, be convenient to installation and maintenance; Long service life has good use value.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of pneumatic valve includes valve body 1; The middle part of valve body 1 has fluid passage 2, and the two ends of fluid passage 2 are respectively inlet/outlet, is provided with rubber pipe 3 in the fluid passage 2; The two ends of rubber pipe 3 are connected with the inner wall sealing of valve body 1; Valve body 1 sidewall be provided with ventilating hole 4 and respectively external suction tude 5 and outlet pipe 6, be separately installed with control valve 7, suction tude 5 external sources of the gas 8 in suction tude 5 and the outlet pipe 6; Have the gap and form airtight air bag 9 between valve body 1 and the rubber pipe 3.
Further, on suction tude 5 or the outlet pipe 6 pressure gauge 10 is installed, is used to measure the air pressure in the valve body 1.
Source of the gas 8 is inflated in valve body 1 through suction tude 5, and the air pressure in the valve body 1 increases gradually, and under the effect of gas pressure, rubber pipe 3 produces distortion, and shrinks to the center gradually, until cutting off fluid passage 2 fully, reaches the purpose of valve closing; Valve body 1 is through 6 pairs of external venting of outlet pipe, and the air pressure in the valve body 1 reduces gradually, and rubber pipe 3 begins to recover under the effect of self tension force, and is unimpeded fully until fluid passage 2, reaches the purpose of valve opening.
Claims (2)
1. a pneumatic valve includes valve body, and the middle part of said valve body has the fluid passage; The two ends of said fluid passage are respectively inlet/outlet; It is characterized in that: be provided with rubber pipe in the described fluid passage, the two ends of said rubber pipe are connected with the inner wall sealing of valve body, said valve body sidewall be provided with ventilating hole and respectively external suction tude and outlet pipe; Be separately installed with control valve in described suction tude and the outlet pipe, the external source of the gas of described suction tude; Have the gap and form airtight air bag between described valve body and the described rubber pipe.
