Abstract
The utility model discloses a pneumatic valve with controllable flow. The pneumatic valve with the controllable flow comprises a valve body. A fluid channel is arranged in the valve body, two ends of the fluid channel respectively are of an inlet and an outlet, a rubber pipe is arranged in the fluid channel, two ends of the rubber pipe are connected with the inner wall of the valve body in a sealing mode, an anti-corrosion layer is arranged on the inner wall of the rubber pipe, and the end wall of the rubber pipe is tightly connected with the end portion of the inlet and the end portion of the outlet of the fluid channel of the valve body through a corrosion-resistance pad. Ventilating openings are formed in the side wall of the valve body and respectively and externally connected with an air inlet pipe and an air exhausting pipe, control valves are respectively installed in the air inlet pipe and the air exhausting pipe, and the air inlet pipe is externally connected with an air source. A gap is arranged between the valve body and the interior fluid channel, and the valve body and the interior fluid channel form a sealed air bag structure. The pneumatic valve is compact in structure, big in sealing area, and capable of achieving opening and closing of the valve by swelling or shrinking of the rubber pipe by air pressure, achieves soft opening and closing, reduces friction, and can prolong service life due to the fact that the corrosion-resistance layer is arranged.
Description
Technical field
The utility model relates to the controlled pneumatic valve of a kind of flow.
Background technique
Valve is widely used in industrial and agricultural production.Existing Air control valve mainly contains the compositions such as pneumatic actuator, pilot line and valve.Its actuator is mainly that the to-and-fro motion by 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 damage because of friction, thereby need reinforcement sealing structure, in addition in using process, mordant material easily corrodes valve interior wall, make working life short, need frequent dismounting and change part.
The model utility content
The technical problem of all solutions of the utility model provides a kind of pneumatic valve of built-in rubber pipe, its compact structure, sealing area is large, control the distending of rubber pipe or shrink the keying that realizes valve by air pressure, thereby make valve realize flexible the keying, reduce friction, be provided with simultaneously anti-corrosion layer, can improve long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
the pneumatic valve that a kind of flow is controlled, include valve body, has the fluid passage in valve body, the two ends of fluid passage be respectively into, outlet, it is characterized in that: be provided with rubber pipe in described fluid passage, the two ends of described rubber pipe are connected with the inner wall sealing of valve body, the rubber pipe inwall is provided with anti-corrosion layer, the fluid passage of described rubber pipe end wall and valve body is advanced, outlet end closely connects by wear-resistant pad, the sidewall of described valve body is provided with ventilating hole and the external suction tude of difference and outlet pipe, be separately installed with control valve in described suction tude and outlet pipe, described suction tude external gas source, have the gap between described valve body and internal fluid channels and form airtight airbag structure.
On described suction tude or outlet pipe, pressure gauge is installed.
The utility model has the advantages that:
The utility model compact structure, sealing area is large, controls the distending of rubber pipe or shrinks and realize the keying of valve by air pressure, thereby making valve realize flexible the keying, reduces friction, is provided with simultaneously anti-corrosion layer, can improve long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
referring to Fig. 1, the pneumatic valve that a kind of flow is controlled, include valve body 1, has fluid passage 2 in valve body, the two ends of fluid passage 2 be respectively into, outlet, be provided with rubber pipe 3 in fluid passage 2, the two ends of rubber pipe 3 are connected with the inner wall sealing of valve body 1, rubber pipe 3 inwalls are provided with anti-corrosion layer 11, the fluid passage 2 of rubber pipe 3 end walls and valve body 1 is advanced, outlet end closely connects by wear-resistant pad 12, the sidewall of valve body 1 is provided with ventilating hole 4 and the external suction tude 5 of difference and outlet pipe 6, be separately installed with control valve 7 in suction tude 5 and outlet pipe 6, suction tude 5 external gas sources 8, have the gap and form airtight air bag 9 between valve body 1 and rubber pipe 3.
Further, on suction tude 5 or outlet pipe 6, pressure gauge 10 is installed, is used for measuring the air pressure in valve body 1.
To the interior inflation of valve body 1, the air pressure in valve body 1 increases source of the gas 8 gradually by suction tude 5, and under the effect of gas pressure, rubber pipe 3 produces distortion, and shrinks to the center gradually, until cut off fluid passage 2 fully, reaches the purpose of valve closing; Valve body 1 is by 6 pairs of external venting of outlet pipe, and the air pressure in valve body 1 reduces gradually, and rubber pipe 3 begins to recover under the effect of self tension force, until fluid passage 2 is fully unimpeded, reaches the purpose of valve opening.
Claims (2)
1. pneumatic valve that flow is controlled, include valve body, has the fluid passage in valve body, the two ends of fluid passage be respectively into, outlet, it is characterized in that: be provided with rubber pipe in described fluid passage, the two ends of described rubber pipe are connected with the inner wall sealing of valve body, the rubber pipe inwall is provided with anti-corrosion layer, the fluid passage of described rubber pipe end wall and valve body is advanced, outlet end closely connects by wear-resistant pad, the sidewall of described valve body is provided with ventilating hole and the external suction tude of difference and outlet pipe, be separately installed with control valve in described suction tude and outlet pipe, described suction tude external gas source, have the gap between described valve body and internal fluid channels and form airtight airbag structure.
2. the controlled pneumatic valve of a kind of flow according to claim 1, is characterized in that: on described suction tude or outlet pipe, pressure gauge is installed.
