Description

[Detailed Description of the Invention] This invention relates to a fluid pressure manual adjustment valve used in a fluid pressure pine surger.

Devices that utilize fluid pressure, such as pneumatic pine surge devices, are preferably structured so that the pine surge pressure can be adjusted as appropriate during use so that a pine surge effect can be obtained according to the user's preference. In that case, the fluid pressure adjusting means may be built into the fluid pressure generating device itself, but it goes without saying that operability is better if it can be operated at hand. To achieve this, a fluid pressure adjustment valve should be installed in the middle of a fluid pipe that supplies fluid pressure so that the fluid pressure can be adjusted quickly. It is required that the structure is simple, the weight can be easily reduced, the reliability is high, and the handling is excellent.

This idea was made in consideration of the above-mentioned circumstances, and it is installed in the middle of the fluid pipe that supplies fluid to the fluid pressure pine surge device, so that the fluid pressure can be adjusted quickly and easily manually according to the user's preference. It is an object of the present invention to provide a fluid pressure manual adjustment valve for a fluid pressure pine surge device that can be used in a fluid pressure pine surge device.

Hereinafter, embodiments of this invention will be described based on the drawings.

Figure 1 shows an example of this invention.
The valve housing 1 is an upper valve housing 1
The valve housing 1a is divided into a middle valve housing 1b and a lower valve housing 1c, and when these are assembled, a fluid chamber is formed inside. A communication hole 2 is provided in the intermediate valve housing 1b to communicate the fluid chambers with each other. Further, the lower valve housing 1c is provided with a fluid inlet 3 and a fluid outlet 4,
It allows the introduction of fluid into the fluid chamber and the evacuation of fluid from the fluid chamber. A hollow sliding shaft 5 passes through the fluid chamber so as to be slidable in the vertical direction.

Further, a diaphragm 11 is provided between the upper valve housing 1a and the intermediate valve housing 1b, and a lower washer member 13 is attached to the male threaded portion 12 formed at the upper end portion of the sliding shaft 5.
1 and the upper washer member 14 are sequentially inserted and tightened with a nut 15 to fix the upper end of the sliding shaft 5 to the diaphragm 11. A coil spring 17 is disposed between the circular groove 16 formed in the upper valve housing 1a and the upper washer member 14 to regulate the positions of the diaphragm 11 and the sliding shaft 5. Further, a manual operating member 20 is provided in the upper valve housing 1a so as to be slidable in the vertical direction, and its lower end portion is brought into contact with the upper end of the sliding shaft 5.

Further, a stepped portion 21 having a different diameter is formed in the portion of the sliding shaft 5 located inside the fluid chamber, and an elastic valve member 22 is fixed to the stepped portion 21. A valve hole 23 is provided between the elastic valve member 22 and the lower valve housing 1c, so that a fluid discharge valve 24 is formed between the elastic valve member 22 and the valve hole 23.

Next, to explain the operation, a fluid pipe connects the fluid inlet 3 and a fluid pressure generating device (not shown), and a fluid pipe connects the fluid outlet 4 and a compression bag for a pine surger (not shown), for example. Suppose we did. Therefore, when the fluid pressure generating device is activated when starting pine surge, pressurized fluid tries to be supplied to the pressure bag for pine surge device through the fluid inlet 3, fluid chamber, and fluid outlet 4. When the fluid pressure rises slightly, it presses the diaphragm 11 in the fluid chamber, causing the sliding shaft 5 to slide slightly upward, causing the elastic valve member 22 and the valve hole 23 to
Since they are separated and the fluid discharge valve 24 opens, the fluid is continuously discharged and the fluid pressure does not increase much. Next, when the user pushes in the manual operation member 20 at the desired time, the elastic valve member 22 closes the valve hole 23 and the fluid discharge valve 24 is closed, so that the fluid flowing in from the fluid inlet 3 is blocked. The fluid pressure is gradually increased by being supplied to the compression bag, increasing the pine surge pressure. Therefore, when the manual operation member 20 is loosened or released after performing pine surge for a predetermined time according to the user's preference, the fluid discharge valve 24 opens again and discharges the fluid inside the fluid chamber to the outside of the valve. The fluid supplied from the pressure generator is also continuously discharged.

FIG. 2 shows another embodiment of this invention, in which the configuration of the fluid discharge valve 24 in FIG. 1 is changed, but the other components are completely the same. That is, the through-valve hole 25 is provided in the fluid chamber side portion of the hollow sliding shaft 5, and the through-valve hole 25
A fluid discharge valve 24 is formed between the intermediate valve housing 1b and the intermediate valve housing 1b. Even in this case, the manual operation member 2
0 is not pushed in, the fluid inside the fluid chamber is discharged to the outside of the valve through the through-valve hole 25, and pine surge pressure is not applied. Also, when the manual operation member 20 is pushed in, the through-valve hole 25 is inserted into the intermediate valve housing. 1b, the fluid discharge valve 24 is closed, and fluid is supplied to the compression bag for the pine surger to increase the pine surge pressure.

As described above, according to the fluid pressure manual adjustment valve for fluid pressure pine surge equipment of this invention, it is possible to freely adjust the pressure of pine surge equipment using fluid pressure at hand, and when the valve is not operated, the fluid is Since the fluid is discharged to the outside, fluid is not supplied inadvertently, and the structure is simple and weight can be easily reduced.
