Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- Fig. 3 refering to fig. 1, the noise elimination drainage clamp of 120/104 main valve and its pop valve, including drainage tube, centre pilot are fixed
Position circle 2 and clamping lever, the centre pilot locating ring 2 are connected to drainage tube, and can deeply be braked and be determined in valve outlet
Position, the clamping lever can closely stabilization be connected to braking valve outlet by drainage tube, the drainage tube other end connection flexible pipe
To muffler to eliminate noise.
The drainage clamp referring to Fig. 1,104 main valves used when brake valve is 104 main valve are eliminated the noise, due to 104 main valves
Balanced portion's exhaust outlet and service portion exhaust outlet in one plane, not it requires that device can be directed at the two exhaust outlets simultaneously
And pinch seal.To prevent the gas of a certain exhaust outlet discharge from entering in another exhaust outlet by drainage tube, to test result
It impacts, unidirectional shut-off damper is installed in the corresponding position of drainage tube, gas can only be discharged from drainage tube, cannot reversely fall
Stream.
The gas of balanced mouth discharge is drained by drainage tube A11.One end installation centers of the drainage tube A11 with bent angle is led
To locating ring 2, sealing adjustable frames 31 are installed outside locating ring, have Gask-O-Seal A51 in pedestal and locating ring.Drainage tube
The other end of A11 is welded on connecting tube A415, and drainage tube A11 has unidirectional shut-off damper with the positions connecting connecting tube A415,
Prevent the air that service portion exhaust outlet is discharged from entering balanced portion's exhaust outlet by drainage tube A11.
Drainage tube B12 is welded on connecting tube A415, in other end connection flexible pipe to muffler.Connecting tube A415 is by two
Divide and dock, center culvert connection, there is sealing ring sealing in junction.It, can at connecting tube A415 docking when operating clamping lever
It is rotated.
Drainage tube C13 is L-shaped, one end installation center guide-localization circle 2, locating ring outside installation sealing adjustable frames
31, there is Gask-O-Seal A51 in pedestal and locating ring.The other end of drainage tube C13 is welded on drainage tube B12, drainage tube C13
Have unidirectional shut-off damper with the positions connecting drainage tube B12, prevent the air of balanced portion's exhaust outlet discharge by drainage tube C13 into
Enter service portion exhaust outlet.

It is entered in muffler by drainage tube D14 to the gas in drainage tube E15.The drainage tube E15 other ends are connected to be delayed with semi-automatic
The sealing for solving the connection of valve handle portion drains seat B33, which connects the sealing being connected to semi-automatic alleviation valve outlet
Seat C34 is drained, is communicated inside the two drainage seats, is because the two gas vents of 120 main valves are while air draft.
Push rod is installed in the directions vertical with deck plate is tested the sealing drainage seat B33 of semi-automatic graduated release valve handle portion
61, push rod 61 is mounted in push rod guide cylinder 62, has resetting spring in push rod guide cylinder 62.Test the cylinder piston on deck plate
Bar pushes push rod 61, push rod 61 to push semi-automatic graduated release valve handle, completes test action.When cylinder piston rod retraction, push rod 61
It is returned to initial position under the active force of resetting spring.
There are gasket in the upper edges sealing drainage seat B33 of semi-automatic graduated release valve handle portion, semi-automatic alleviation valve outlet
2 outer wall of centre pilot locating ring is cased with gasket, seals.
Handle setting plate 425 is mounted on connecting pole 424, and handle B421 is fixed on handle setting plate 425 by pin B422
On, handle B421 and pushing claw A426 are attached by connecting rod B423, claw A426 leading portions is pushed and pushing fastening is installed
Bolt 427.
When operation, 120 main valves are mounted on testing stand, pull handle B421, make pushing claw A426 and connecting pole 424 it
Between open certain angle, meet the space needs of installation.
The sealing of exhaust outlet of main valve is drained into seat A32, the sealing of semi-automatic graduated release valve handle portion drains seat B33, semi-automatic
The sealing drainage seat C34 for alleviating valve outlet is directed at corresponding exhaust outlet, makes the gasket on each drainage seat that each row be completely covered
Air port edge, and 61 top of push rod is directed at cylinder piston rod.By lower handle B421, pushes the front ends claw A426 and move downward, under
The valve deck that fixing bolt 427 compresses 120 main valves is compressed, whole device is fixed.
When each vent of 120 main valves, gas is discharged into drainage tube, and drainage tube caliber is more than diameter of outlet,
So the device does not influence the flow and speed of exhaust.
Referring to Fig. 3,120/104 pop valve used when brake valve is 120/104 pop valve is eliminated the noise, drainage clamp, draw
In the connection flexible pipe to muffler of the one end flow tube F16, the other end, which is provided with, adjusts screw thread 7, centre pilot locating ring 2 and external positioning
Circle 21 is an entirety, on the adjusting screw thread 7 of drainage tube F16, locating ring can on adjusting screw thread 7 limited pendulum
It is dynamic, to adapt to the error that valve body is generated in casting and assembly.There is annular between centre pilot locating ring 2 and external locating ring 21
Gasket B52 plays a part of to seal valve port.Link block B434 is vertically welded on drainage tube F16, and handle C431 is by pin C432
It is fixed on link block B434.Limited block 435 is welded on link block B434, and position is in front of handle C431 bent angles, opponent
Handle C431 motion directions provide constraints.The one end connecting rod C433 is fixed on handle C431 bent angles position, the other end by pin C432
It is fixed on by pin C432 and pushes the rear portions claw B436.It pushes claw B436 and the upper of link block B434 is fixed on by pin C432
Side.Pushing the front ends claw B436 has platen 437, can push down urgent valve deck.
When operation, pop valve is mounted on testing stand, and handle C431 is lifted up, pushing claw B436 is made to lift upwards
It rises, forms opening.Centre pilot locating ring 2 is directed at urgent valve outlet, extend into inside valve port, urgent valve outlet edge with
Gask-O-Seal B52 contacts between centre pilot locating ring 2 and external locating ring 21, handle C431 are pressed downward, the company of drive
Bar C433 action, makes the platen 437 on pushing claw B436 move downward, is contacted with urgent valve deck, then with forcing handle C431,
The device is fixed.At this point, Gask-O-Seal B52 is in close contact with urgent valve outlet edge, sealing function is played.
When pop valve vent, gas is discharged into drainage tube, drainage tube caliber is more than diameter of outlet, so should
Device does not influence the flow and speed of exhaust.
Only presently preferred embodiments of the present invention is explained in detail above, but the present invention is not limited to above-described embodiment,
Within the knowledge of a person skilled in the art, it can also make without departing from the purpose of the present invention each
Kind variation, various change should all be included in the protection scope of the present invention.
