[Problems to be solved by the invention]

 In this conventional pipe joint, the contact between the O-ring 17 and the tapered surface 18 is slight, and it is difficult to adjust the amount of fluid blown out from the duster nozzle. There was a case. Further, since the duster nozzle 19 is provided obliquely with respect to the fluid passage 20, it is difficult to adjust the angle to remove dust because the duster nozzle 19 is too close to an air device mounted on the periphery.

According to the present invention, the communication port is provided so as to be perpendicular to the fluid passage so that the presence of peripheral equipment does not hinder the flow direction of the fluid discharge hole to be a direct downward direction, so that it is easy to grasp the pipe joint. It is an object of the present invention to provide a pipe joint with a duster capable of finely adjusting the blowout amount from a fluid blowout hole by making the contact angle between the duster adjusting ring and the tapered surface sharp, while making it easy to use. .

By operating the push button, the ejection direction is orthogonal to the fluid passage, so that the spraying direction can be reliably controlled with respect to peripheral devices.

In the second invention, the communication port between the duster nozzle and the fluid passage is provided with a tapered surface, and the fluid outlet is opened and closed between the duster adjusting ring attached to the valve stem to open and close the fluid from the fluid outlet. The amount of blowing can now be fine-tuned. In the third invention, since the pressure receiving area on the push button side is larger than the pressure receiving area received by the valve body when the valve body is closed, even when high-pressure compressed air or the like flows in the fluid passage. Therefore, force is always applied in the direction to close the valve. In addition, since the dust outlet nozzle is provided with the fluid outlet, the fluid can be ejected in a direction perpendicular to the fluid passage, and the duster nozzle also serves as a spring holder, so that the duster nozzle can be shortened.

In the fourth invention, the taper surface provided in the communication port of the duster nozzle is made to have an acute angle, so that the contact surface with the duster adjusting ring can be finely adjusted. Therefore, the amount of fluid blown out from the fluid blowout hole can be controlled. Can be.

【Example】

 The pipe joint with a duster of the present invention will be described with reference to FIGS. FIG. 1 is a partial cross-sectional overall view of a pipe joint with a duster of the present invention, and FIG. 2 is an enlarged partial cross-sectional overall view of the same. 1 is a pipe joint main body, 2 is a sleeve provided on the outer periphery of the pipe joint main body, and 3 is a tool locking ball pushed out by the sleeve 2 toward the center. The tools to be locked include a spray gun, an air sander, an air glider and the like.

Reference numeral 4 denotes a fluid passage, and reference numerals 5 and 6 denote communication ports, which are provided at positions perpendicular to the middle of the fluid passage 4. The communication port 5 is on the push button side, and the communication port 6 is on the valve body side. Reference numeral 7 denotes a nipple for connecting to an air hose. Reference numeral 8 denotes a valve stem, which is provided so that the fluid passage 4 is orthogonal to the end by inserting an end portion into the communication ports 5, 6.

Reference numeral 9 denotes a valve element provided at one end of the valve rod 7. A duster adjusting ring 10 is provided on the valve body 9 of the valve rod 8 so that the communication port 6 can be sealed. Reference numeral 11 denotes a tapered surface, which is provided on the communication port 6 side and is formed at an acute angle so that the duster adjusting ring 10 can be in contact with the compressed air blowout.

Reference numeral 12 denotes a closing ring, which is provided in the communication port 5 and can seal the valve stem 8 and the push button 16. Reference numeral 13 denotes a spring which is in contact with the valve element 9 of the valve rod 8 and is normally biased in a direction to close the valve element. A duster nozzle 14 is provided on the communication port 6 side and also serves as a spring holder. As an engagement means to the pipe joint main body 1, a screw mounting by a screw or the like is possible. When the screw is installed, the duster nozzle can be easily assembled, and the protruding state from the pipe joint can be finely adjusted. In addition, after the valve rod 8 is inserted into the communication ports 5 and 6 during the assembly, the spring 13 is moved. It can be easily done by loading and attaching the duster nozzle 14.

Reference numeral 15 denotes a fluid outlet, which is provided in the duster nozzle 14 and can blow out compressed air from the fluid passage 4 by adjusting the valve element 9. Reference numeral 16 denotes a push button, which is attached to the valve stem 8 to enable external valve operation. The operation of the present invention in the above configuration will be described.

Since the pressure receiving area received by the valve body 9 is smaller than the pressure receiving area on the push button 14 side, the fluid does not blow out from the fluid blowout hole 15 even when the fluid such as the compressed air has a high pressure. . Further, since a force is applied to the valve body 9 by the spring 13 to close the valve body 9, the valve body 9 can be kept closed even when there is no compressed air or the like in the fluid passage 4.

Since the pressure receiving area and the spring are provided as described above, the operation of the push button 16 is light and fine adjustment is easy. Since the spring 13 is housed inside the duster nozzle 14, the nozzle can be made compact. The duster nozzle 14 is provided with a fluid blowout hole 15 so that the blowout direction can be made perpendicular to the fluid passage, so that the duster nozzle 14 can be easily directed to a device requiring duster action.

Further, by making the tapered surface 11 in contact with the duster adjusting ring 10 an acute angle, the gap between the duster adjusting ring 10 and the duster adjusting ring 10 can be finely adjusted, and the amount of air blown out from the fluid outlet hole 15 of the duster nozzle can be adjusted. It is possible.

[0020]

[Effect of the invention]

 The pipe joint of the present invention has a push button and a fluid outlet through a valve stem so that the fluid passage is orthogonal to the fluid passage, and a spring receiver is provided in the duster nozzle to make it compact, so it can be grasped with one hand. Easy, easy to operate and safe. The fluid blowout hole can blow out the fluid from the space between the fingers with a proper direction to the portion where dust is generated. In the case of conventional oblique blowing, compressed air hits the surrounding air equipment, which results in reflection and further scattering of dust, but this inconvenience has been resolved.

Further, by making the tapered surface an acute angle, it is possible to finely adjust the blowout amount from the fluid blowout hole.
