Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake / exhaust valve of a dry suit in which an intake valve and an exhaust valve, each of which is a push-in type angle valve, are integrally provided so as to connect the inlet passages and function independently.

More specifically, the present invention relates to an intake / exhaust valve of a dry suit for supplying air from an air tank to the inlet passage of the exhaust valve at the time of exhaust to forcibly exhaust air and exhaust the air in the dry suit to every corner. It is a thing.

[0003]

2. Description of the Related Art Conventionally, a dry suit in which water does not enter the body and clothes of a diver, reduces the buoyancy by discharging the air in the dry suit when the diver is submerged in water, and the air in the dry suit when floating. The air in the tank is supplied to increase buoyancy. Therefore, the dry suit is required to have an intake / exhaust valve for letting air in and out of the dry suit.

However, various intake / exhaust valves of this type of dry suit are disclosed, such as Japanese Utility Model Laid-Open No. 48-60299 and Japanese Patent Laid-Open No. 63-25193, which is the invention of the present inventor.

Among them, the one disclosed in Japanese Utility Model Laid-Open No. 48-60299 is one in which an intake valve and an exhaust valve are provided on the left and right sides of the chest, and a natural exhaust valve is used as the exhaust valve.

In Japanese Patent Laid-Open No. 63-25193, an exhaust valve is arranged on the outer circumference of an intake valve so as to be integrated. When the pressing portion on the inner circumference is pressed, the intake valve opens and the air tank opens. Air is supplied into the dry suit. When exhausting, push the inner pressing part to open the intake valve,
The exhaust valve is opened by pressing the pressing portion on the outer circumference. Then, the air in the dry suit passes through the gap of the exhaust valve and is ejected to the exhaust hole, and the pressure of the air passing through the gap at high speed is lowered (Bernoulli's theorem). The air in the dry suit is forcibly exhausted together with the air in the air tank.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the No. 9 publication, a natural exhaust valve is used as the exhaust valve, so air in the vicinity of the exhaust valve can be exhausted,
There is a problem that the air accumulated in other parts cannot be exhausted. Therefore, the diver himself moves in the water,
It is necessary to guide the air that has accumulated in other parts to the vicinity of the exhaust valve to exhaust it, and it is difficult for beginners to guide the air that has accumulated in other parts to the vicinity of the exhaust valve, and it is not possible to exhaust it sufficiently. It was That is, there is a problem that the air in the dry suit does not escape well for a beginner, which makes it difficult to dive.

In this case, the instructor is
In order to give advice to beginners who cannot exhaust air and to assist exhaust operation, there was a problem that beginners who were able to exhaust air well did not wait for the instructor's instruction during that time and took arbitrary actions.

There is a drawback that a beginner who cannot exhaust sufficiently cannot dive unless he / she attaches an extra weight, and the movement in water is restricted by the weight.

Further, according to Japanese Patent Laid-Open No. 63-25193, since the intake valve is arranged inside the exhaust valve, the check valve and the packing are attached to the exhaust valve to make the exhaust valve watertight. Had the problem of being difficult.

Further, since the air from the intake valve is supplied in the radial direction below the suction gap of the exhaust valve, there is a problem that this air does not effectively pass through the suction gap of the exhaust valve. Therefore, there is a problem in that a high-speed air flow passing through the gap is unlikely to occur and it is difficult to forcibly exhaust the air in the dry suit.

Further, since the O-ring is used to prevent water leakage of the intake / exhaust valve, the operation of the intake / exhaust button is performed by sliding the O-ring inserted in the cylindrical body on the wall surface. It has a drawback that it requires a large amount of force to operate and is difficult to operate.

Further, in water, the O-ring for preventing water leakage of the exhaust valve is filled with water. Therefore, when the pressing portion of the exhaust valve is pushed, a high-speed air flow is unlikely to occur in the suction gap of the exhaust valve. In addition to this, there was a drawback that water leaked from the gap of the exhaust valve into the dry suit.

It is an object of the present invention to provide an intake / exhaust valve for a dry suit that allows even beginners to easily exhaust air in every corner of the dry suit and easily enter (dive).

Further, the intake air from the inlet passage of the exhaust valve is used for forced exhaust so that it can be exhausted in a faster time than that of natural exhaust, and the pressure can be adjusted to the atmospheric pressure at the submerged water depth. It is an object of the present invention to provide an intake / exhaust valve for a dry suit that can be adjusted promptly.

Furthermore, by providing a check valve or packing in the exhaust valve, it is an object to provide an intake / exhaust valve of a dry suit in which water leakage does not occur even if the push valve rod of the exhaust valve is pushed during exhaust. And

Further, since the air in the dry suit can be exhausted to every corner, it is not necessary to attach a weight more than necessary to dive, and to provide an intake / exhaust valve for the dry suit that makes the movement of the diver underwater more comfortable. The purpose is to do.

It is pushed up by the air flow flowing between the middle cylinder 8 and the middle cylinder 8 and flowing into the ventilation hole 93 of the middle cylinder presser 9. The air inside the dry suit is exhausted from the exhaust port 201 of the exhaust cover 20 to the exhaust valve box 1
3 is sucked out to the plurality of exhaust ports 143 of the exhaust valve cover 14 through the plurality of discharge holes 136 in the lower surface 131 of
The air in the dry suit can be exhausted to every corner. When the exhaust is finished, the exhaust operation is stopped by releasing the exhaust button 63.

Therefore, the instructor does not need to give any advice or help, and even a beginner can easily exhaust the air in the dry suit to every corner. For this reason, even a beginner can quickly enter, there is no need to attach an extra weight, and the operation in water becomes easy.

When tightening due to water pressure becomes tight due to the depth of diving, the intake button 53 of the intake valve 1 is pressed against the elasticity of the compression coil spring 33, so that the valve rod 3 descends and the small diameter portion 31. Reaches the insertion hole 48 of the large diameter portion 32. Then, the air in the air tank from the inlet passage 11 of the intake valve 1 is dried from the small diameter portion 31 through the insertion hole 48, the outlet passage 12 of the intake valve 1 and the air supply hole 191 of the intake cover 19 as described above. Air is supplied into the suit. Therefore, the optimum air pressure can be quickly adjusted according to the diving depth.

At the time of ascending, the intake valve 1
The air intake button 53 is pressed against the elasticity of the compression coil spring 33 to supply air into the dry suit. Further, during ascent, the air in the dry suit expands as the depth becomes shallower. Therefore, the expanded excess air is exhausted by pressing the exhaust button 63 of the exhaust valve 2 in the same manner as described above.
Since it is exhausted by forced exhaust, the exhaust speed is fast, and it is easy to adjust the levitation while keeping the levitation speed constant.

According to the present invention, since the intake valve and the exhaust valve are integrated so that their respective inlet flow paths are connected so as to operate independently, the intake valve and the exhaust valve are operated as if they were separated from each other. It is possible to operate the intake valve and the exhaust valve with a finger without hitting the hand and moving the hand.

Further, since the intake valve and the exhaust valve are not constructed such that the O-ring is interposed between the cylindrical body and the sliding outer wall surface, friction with the O-ring is small, and the intake valve and the intake valve are not operated. The exhaust valve and can be operated lightly.

Further, since the forced exhaust valve is used as the exhaust valve, even the beginner can exhaust the air in the dry suit to every corner in a short time. Therefore, it is not necessary for the diver to move his / her body in the water and guide the air accumulated in the part other than the exhaust valve to the exhaust valve to exhaust it.Easy entry is possible, and it is easy for instructors to teach beginners. Become.

Further, since the air in the dry suit can be exhausted to every corner, it is not necessary to attach a weight more than necessary, which facilitates the operation in water.

Since the exhaust valve is equipped with a check valve and packing, the exhaust valve can be made watertight, and water enters the exhaust valve box and the middle cylinder and the sliding gap between the middle cylinder presser when the exhaust valve operates. It is possible to prevent water leakage into the dry suit.

Further, it can be exhausted in a faster time than that of natural exhaust, and the intake / exhaust valve can be operated according to the atmospheric pressure at the depth of the submerged water, so that the pressure can be quickly adjusted to the atmospheric pressure. Become.

Since the upper valve box of the intake valve is made rotatable with respect to the lower valve box, it is twisted in the tube connected to the air tank through the rubber pipe socket and the plug in the inlet passage on one side of the upper valve box. However, only the upper valve box can be rotated with respect to the lower valve box. As a result, the intake / exhaust valve fixed to the arm or the like can be prevented from being twisted due to twisting of the tube, and discomfort during diving can be eliminated.
