Definitions
- This invention relates to an air operated valve that opens and closes a fluid passage by driving a piston by the pressure of operating air.
- An object of the present invention is to provide an air operated valve suitable for use in a form using a one-touch joint.
- An air operated valve includes a body provided with a fluid passage, a casing provided above the body, a valve body that opens and closes the fluid passage, and opens or closes the valve body in the opening or closing direction.
- the casing comprises an upper casing and a lower casing that are screwed together,
- the piston driving means has a one-touch joint attached to the top of the upper casing.
- One-touch fittings are well-known joints that fix the pipe with the clamping force of the collet chuck built into the main body, and the connection is completed simply by inserting the operating air introduction pipe into the main body. It can be done easily.
- pulling out the operation air introduction pipe from the one-touch fitting it can be easily done by pushing the release bush of the one-touch fitting with one hand and pulling out the operation air introduction pipe with the other hand. Even when it is frequently required, it can be easily attached and detached.
- An air operated valve is a valve that opens and closes a fluid passage by driving a piston by the pressure of operating air, and there has been no such one that has a built-in one-touch joint.
- the conventional air operated valve with the one-touch joint attached has a problem that the height is increased by the amount of the one-touch joint. Also, it may be necessary to use the one-touch fitting and no one-touch fitting separately. Storage or disposal of air operated valves is an issue, and high compatibility between these valves is required.
- the overall height can be lowered by incorporating the one-touch joint.
- the one-touch joint For example, to replace an air operated valve without a one-touch fitting with an air operated valve with a one-touch fitting, it is only necessary to replace the upper casing with an upper casing having a one-touch fitting. Only the upper casing of the air operated valve is provided, and its storage or disposal becomes easy. Furthermore, when the one-touch joint protrudes from the upper part of the valve, if an impact is applied to the one-touch joint from outside during work, the one-touch joint may break at the threaded portion.
- a through-hole is provided in the center of the top wall of the upper casing.
- the through-hole is composed of a small-diameter portion on the lower end side, a large-diameter portion on the upper end side, and an intermediate-diameter female screw portion provided between them.

- the upper end portion of the valve rod is movably inserted into the small diameter portion of the through hole.
- the valve rod is preferably provided with an axial passage extending downward from its upper end and a radial passage extending radially from the axial passage and leading to the operation air introduction chamber.
- the height of the air operated valve with the one-touch joint can be reduced, and the compatibility between the air operated valve without the one-touch joint and the air operated valve with the one-touch joint becomes higher.
- the number of pistons may be one, or may be plural. As the number of pistons increases, the number of operation air introduction chambers is increased, and the number of radial passages extending in the radial direction from the axial passage and leading to the operation air introduction chamber is also increased.
- the piston drive means moves the valve stem by applying operating air to the piston, and may move the valve stem upward and downward, respectively, or in combination with an elastic member such as a compression coil spring.
- the piston drive means moves the valve stem against the urging force of the elastic member by biasing the valve stem with the elastic member so as to be in the normally open position or the closed position. Also good.
- top and bottom are referred to as the top and bottom of the figure (the body side is the bottom and the casing side is the top), but this top and bottom is for convenience, and the top and bottom are reversed. Sometimes it is used from side to side.
- the casing includes the upper casing and the lower casing that are screwed together, and the piston driving means has the one-touch joint that is attached to the top of the upper casing.
- the operation air introduction pipe can be connected simply by inserting the pipe into the pipe, and the piping work becomes easy.
- the upper casing with other parts in common it is possible to obtain an air operated valve with a one-touch joint and an air operated valve without a one-touch joint. Can be made highly compatible.
- the one-touch joint is built in the valve, the height of the valve is not increased more than necessary, and the apparatus can be miniaturized.
- the one-touch joint is not subject to external impact, and the one-touch joint can be prevented from being damaged.
