(Joint part for air brake piping 100)
As shown in fig. 1, the joint portion 100 for air brake piping has a T-shape and has cylindrical portions 110, 120, and 130 communicating with each other via a central communication portion 114.
The cylindrical portion 110 has a large-diameter portion 111, a medium-diameter portion 112, and a small-diameter portion 113 formed in this order from the upper cylindrical portion 110. Further, an inner cylinder portion 131 is formed in the cylindrical portion 130.
The joint part 100 for air brake piping is made of resin. This makes it possible to reduce the weight of the joint compared to a conventional joint having a joint portion for an air brake pipe made of metal such as iron or brass.
(test connector section 200)
The test connector unit 200 is in an open state when a pressure test device, not shown, is connected to the air brake pipe nipple unit 100, and is in a closed state when the pressure test device is removed. Specifically, as shown in fig. 2, test connector section 200 includes: a metal cover member 210 having a through hole 211 formed therein in the axial direction; a valve body 220 that passes through the inside of the through hole 211 in a manner slidable in the axial direction of the through hole 211; a metal valve spring 230 that is disposed in the small-hole portion 113 of the cylindrical portion 110 and biases the valve body 220 so that the valve body 220 protrudes outward from the cover member 210; and a seal 240 (O-ring) disposed in the intermediate hole portion 112, interposed between an inner peripheral surface of the cylindrical portion 110 (an inner peripheral surface of the intermediate hole portion 112) and an outer peripheral surface of the valve body 220 below the communication hole 222 of the valve body 220 in a state where the valve body 220 protrudes outward from the cover member 210, and securing airtightness of the air flow path. The seal 240 is accommodated in a peripheral groove formed by the cylindrical portion 110, the valve body 220, and the cover member 210.
As shown in fig. 2, the through hole 211 includes a small-diameter hole portion 212 for guiding the valve body 220, and a large-diameter hole portion 213 having a larger diameter than the small-diameter hole portion 212. A stepped portion 214 serving as a stopper for restricting the movement of the valve body 220 is formed on the inner wall of the through hole 211.
A screw portion 215 for screwing with the pressure test device is formed on the outer peripheral surface of the lid member 210 at a portion to which the pressure test device is connected.
A rib-shaped protrusion 250 is formed on the outer peripheral surface of the press-fitting portion 217 of the cover member 210 that is press-fitted into the air brake pipe coupling portion 100. Thus, when the cap member 210 is press-fitted into the cylindrical portion 110, the test connector portion 200 and the air brake piping joint portion 100 can be integrated by the protrusion 250 biting into the inner wall of the large diameter portion 111.
As shown in fig. 2, an air discharge hole 221 is formed in the valve body 220, and the air discharge hole 221 is perforated in the axial direction from a surface on one end side and opened in the outward direction, and has a bottom on the other end side. A communication hole 222 penetrating the outer circumferential surface of the valve body 220 from the inner circumferential surface of the air discharge hole 221 is formed on the other end side of the air discharge hole 221. As shown in fig. 3, the communication hole 222 is formed at the following position: when the valve element 220 is pushed in the direction of arrow a, at least a part of the communication hole 222 faces the inside of the small-diameter hole portion 113 located on the other end side of the seal 240, whereby the air discharge hole 221 communicates with the air flow passage inside the air brake piping joint portion 100 via the small-diameter hole portion 113, and the air inside the air brake piping joint portion 100 can be sent to the pressure test equipment.
An abutting portion 223 is formed on the outer peripheral surface of the other end side of the valve body 220, one end of the valve spring 230 is attached to the abutting portion 223, and the outer diameter of the abutting portion 223 is larger than other portions so as to abut against the stepped portion 214 by the biasing force of the valve spring 230.
In a state where the device for pressure test is not connected to the test connector portion 200, as shown in fig. 2, the valve element 220 is biased toward one end side by the valve spring 230, and the communication hole 222 is located in the small-diameter hole portion 212 located on one end side of the seal 240, so that air in the air flow path of the air brake pipe coupling portion 100 is not guided from the communication hole 222 to the air discharge hole 221 (closed state).
On the other hand, as shown in fig. 3, in a state where the pressure test device (not shown) is connected to the test connector unit 200, one end surface of the valve element 220 abuts against the pressure test device, the valve element 220 is pushed down in the through hole 211 against the urging force of the valve spring 230, and the communication hole 222 provided in the valve element 220 moves to a position below the seal 240, whereby air in the air flow path of the air brake pipe joint unit 100 is guided from the communication hole 222 to the pressure test device through the air discharge hole 221 (open state).
The valve element 220 may be made of resin or metal. The valve spring 230 may be, for example, a coil spring.
As a method of assembling the test connector portion 200, for example, in the cylindrical portion 110, the valve spring 230 is inserted into the small-diameter hole portion 113, the seal 240 is inserted into the middle-diameter hole portion 112, the valve body 220 is inserted into the cylindrical portion 110, and finally, the cap member 210 is pressed into the large-diameter hole portion 111, and the ridge protrusion portion 250 is engaged with the inner wall of the large-diameter hole portion 111 and fixed.
(adapter for device connection 300)
The device connecting adapter 300 is a member for connecting a brake-related component to the air brake piping joint 100, and includes a metal housing 310 and a rubber gasket member 320 for ensuring airtightness, as shown in fig. 1.
A through passage 311 is formed in the housing 310, and the through passage 311 is used to pass air from inside the brake related component into the air brake piping joint part 100.
A screw portion 312 for screwing with a brake related member is formed on the outer periphery of a portion of the housing 310 on the side to which the brake related member is connected.
A gasket groove 314 for disposing a gasket member 320 is formed on the outer periphery of the press-fitting portion 313 of the housing 310 press-fitted into the cylindrical portion 120. A rib-shaped protrusion 330 is formed on the outer periphery of the press-fitting portion 313. Thus, when the adapter 300 for connecting equipment is press-fitted into the cylindrical portion 120, the projection 330 bites into the inner wall of the cylindrical portion 120, and the adapter 300 for connecting equipment and the air brake pipe joint portion 100 can be integrated.
(adapter part for pipe connection 400)
The pipe connection adapter part 400 is a member for connecting the pipe 500 to the air brake pipe coupling part 100, and as shown in fig. 1, includes a resin grommet 410 rotatably installed therein, a metal cap 420 for fixing the grommet 410 in a slip-off state, a metal collet 430 disposed to be able to advance and retreat with respect to the cap 420, and a rubber seal 440 for securing airtightness.
The back ring 410 is formed with a tapered surface 411 for expanding the diameter of the collet 430 as described below. A collet claw 431 and an inner tapered surface 433 for holding the tube 500 in the cylindrical portion 130 are formed on the inner periphery of the collet 430, and an outer tapered surface 432 is formed on the outer periphery. A rib-shaped protrusion 450 is formed on the outer circumference of the cover 420. Thus, when the cap 420 is press-fitted into the cylindrical portion 130, the protrusion 450 bites into the inner wall of the cylindrical portion 130, and the pipe connector portion 400 and the air brake pipe coupling portion 100 can be integrated.
When the pipe coupling adaptor 400 applies internal pressure to the inserted pipe 500 and displaces the collet 430 in the direction of removal of the pipe 500 from the cover 420, the collet 430 contracts in diameter along its outer circumferential tapered surface 432, and as shown in fig. 1, the collet fingers 431 pierce the pipe 500 and firmly grip the pipe 500. On the other hand, when the collet 430 is displaced in the direction opposite to the removal direction of the tube 500 (the insertion direction of the tube 500) with respect to the cover 420 by a special tool, the tapered surface 411 of the grommet 410 comes into contact with the inner peripheral tapered surface 433 of the collet 430 to expand the diameter of the collet 430, and the collet fingers 431 inserted into the tube 500 are released, whereby the tube 500 is released.
[ method of use ]
As a method of using the joint 1 with a test connector, for example, an air tank is connected to the device connecting adapter 300, a tube 500 is connected to the tube connecting adapter unit 400, and when the air brake assembling vehicle is operated in a flat state, the pressure test device is not connected to the test connector unit 200, and air output from the air tank is sent to the air tank, an air valve, an air actuator, and the like through the tube 500 via the joint 1 with a test connector. In this case, the joint 1 with the test connector is lighter than a conventional joint, and is therefore more resistant to vibration generated by the running of the air brake equipped vehicle. On the other hand, in the case of performing a test of a pressure test (inspection), the pressure of the air brake pipe between the air tank and the air tank, the air valve, the air actuator, and the like can be measured simply and quickly by merely connecting the pressure test device to the test connector section 200.
In the connector with test connector 1, as shown in fig. 1, the sharp and hard rib-shaped protrusions 250, 330, 450 formed on the cover member 210, the device connecting adaptor 300, and the cover 420, respectively, are engaged with the inner walls of the large-diameter portion 111 and the cylindrical portions 120, 130, respectively, so that they can be easily and firmly integrated.
In the present embodiment, the T-shaped joint portion 100 for air brake piping is used, but the present invention is not limited thereto, and for example, an F-shaped joint portion for air brake piping or the like may be used.
In the present embodiment, the pipe connecting coupling part 400 is used, and the pipe connecting coupling part 400 uses the collet 430 having the collet claw 431 formed therein, but the present invention is not limited to this, and for example, a pipe connecting coupling of a lock ring type described in japanese patent No. 4300459 and japanese patent No. 4468145 may be used as long as the pipe connecting coupling part can be integrated with the air brake pipe coupling part.

Thus, when the adapter 300 for connecting equipment is pressed into the cylindrical portion 120 ', the projection 340 bites into the inner wall of the cylindrical portion 120 ', and the adapter 300 for connecting equipment and the joint portion 100 ' for air brake piping can be integrated.
(adapter part for pipe connection 400)
The pipe coupling adapter portion 400 is the same as the above-described embodiment, and therefore, the same reference numerals are given thereto and the description thereof is omitted.
[ method of use ]
As a method of using the joint 1 ' with a test connector, for example, an air tank is connected to the device connecting adapter 300, the tube 500 is connected to the tube connecting adapter unit 400, and when the air brake assembling vehicle is operated in a flat state, the pressure test device is not connected to the test connector unit 200 ', and air output from the air tank is sent to the air tank, the air valve, the air actuator, and the like through the tube 500 via the joint 1 ' with a test connector. In this case, the joint 1' with the test connector is lighter than a conventional joint, and is therefore more resistant to vibration generated by the running of the air brake equipped vehicle. On the other hand, in the case of performing a test of a pressure test (inspection), the pressure of the air brake pipe between the air tank and the air tank, the air valve, the air actuator, and the like can be measured simply and quickly by merely connecting the pressure test device to the test connector portion 200'.
In the joint 1 'with a test connector, as shown in fig. 4, sharp and hard rib-shaped protrusions 270, 340, 450 formed on the test connector part 200', the device connection adapter 300, and the pipe connection adapter part 400, respectively, can be made to bite into the respective inner walls of the cylindrical parts 110 ', 120', 130, and can be easily and firmly integrated.
The joint 1 'with the test connector uses the T-shaped air brake piping joint portion 100', but the present invention is not limited to this, and for example, an F-shaped air brake piping joint portion or the like may be used.
In the joint 1 ' with a test connector, the test connector section 200 ' in which the valve spring 230 ' is supported by the snap ring 251 is used, but the present invention is not limited to this, and for example, a test connector section in which the other end of the housing 219 is plastically deformed toward the center point side of the large-diameter hole section instead of the snap ring to form a caulking section (not shown) and the valve spring is supported by the caulking section may be used.
In the joint 1' with a test connector, the adapter part 400 for pipe connection is used, and the clamp 430 having the clamp claw part 431 is used for the adapter part 400 for pipe connection, but the present invention is not limited to this, and a pipe connection adapter of a lock ring type described in japanese patent No. 4300459 and japanese patent No. 4468145, for example, may be used as long as it can be integrated with the joint part for air brake piping.
