Description

Technical Field

[0001] This utility model relates to the field of brake system connector technology, specifically a cone-seal exhaust connector. Background Technology

[0002] In the braking system of port quay cranes, the brake discs generate heat and gas due to friction during operation. If these are not discharged in time, it may lead to a decrease in braking performance and accelerated wear of components. Currently, most exhaust solutions on the market use a structure with a one-way valve installed in the flow channel for exhaust, which has the drawbacks of being prone to clogging, having a short lifespan, and being inconvenient to maintain. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a cone-seal venting joint with simplified structure, convenient maintenance and adaptability to the venting requirements of quay crane brake discs, comprising:

[0004] Hose connector: used to connect to a hose, with a first threaded connecting post integrally formed on its right end, and a tapered head at the end of the first threaded connecting post;

[0005] Valve block connector: used to connect to the valve block, with a threaded connecting sleeve on the left end and a tapered groove on the right end face of the threaded connecting sleeve;

[0006] The first threaded connecting post is threaded into the threaded connecting sleeve, and the tapered head is placed in the tapered groove. A vent hole is vertically opened on the tapered head, and the vent hole is connected to the first vent channel in the hose connector. A second vent channel is opened inside the valve block connector, and the second vent channel is connected to the vent hole through the gap between the tapered groove and the tapered head.

[0007] As a preferred embodiment of this utility model, when the first threaded connecting column and the threaded connecting sleeve are tightened, the conical head and the conical groove fit together to block the gas flow (normal sealing state); when loosened, a gap is generated between the conical head and the conical groove, and the gas flows (exhaust state); the gas is discharged sequentially through the first exhaust channel inside the hose connector, the exhaust hole, the gap between the conical groove and the conical head, and the second exhaust channel inside the valve block connector.

[0008] As a preferred embodiment of this utility model, the left end of the hose connector is integrally formed with a conical sleeve and a fastening groove. The hose is fitted through the conical sleeve and fixed with fasteners and fastening groove.

[0009] As a preferred embodiment of this utility model, the outer surface of the middle part of the hose connector is provided with a hexagonal screw plate, which facilitates the rotation of the hose connector.

[0010] As a preferred embodiment of this utility model, the right end of the valve block connector is provided with a second threaded connecting post for assembly with the valve block.

[0011] As a preferred embodiment of this utility model, the outer peripheral surface of the left end of the valve block connector is provided with a hexagonal nut for easy tightening and assembly.

[0012] As a preferred embodiment of this utility model, a sealing groove is provided on the right end face of the hexagonal nut, and the sealing groove is used to place the ED sealing ring.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] This invention replaces the moving parts of a one-way valve with a conical seal formed by a conical head and a conical groove, reducing vulnerable parts, adapting to port salt spray environments, and significantly extending service life. Under normal conditions, tightening achieves a seal; when venting is needed, manual loosening allows venting through the gap, eliminating the need for automatic components and preventing venting failure due to blockage. For cleaning, simply unscrew the hose connector and valve block connector to clean the vent hole, conical surface, etc., without disassembling complex flow channels, making operation convenient. The hose is fixed by a conical sleeve and a fastening groove, and the valve block connector is assembled with the valve block via a second threaded connecting post. Combined with the sealing effect of the ED sealing ring, the overall connection is firm and has good sealing performance. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] like Figs. 1 to 3 As shown, a cone-seal exhaust connector includes a hose connector 1 and a valve block connector 2;

[0022] The left end of the hose connector 1 is integrally formed with a conical sleeve 3 and a fastening groove 4. The hose (not shown in the figure) is fitted over the conical sleeve 3 and fixed by clamping (fastener) into the fastening groove 4. The outer surface of the middle part is provided with a hexagonal threaded plate 5. The first threaded connecting post 7 at the right end is integrally formed with the conical head 9. The vent hole 8 on the conical head 9 is connected to the first venting channel 6 inside the hose connector 1.

[0023] The left end of the valve block connector 2 is provided with a threaded connecting sleeve 11, the outer surface of which is a hexagonal nut 10, and the right end face of the hexagonal nut 10 is provided with a sealing groove 13 (with built-in ED sealing ring); the right end face of the threaded connecting sleeve 11 is a tapered groove 12, and the internal second exhaust channel 15 extends through to the right end of the second threaded connecting post 14.

[0024] The working principle of this utility model:

[0025] Normal sealing: Tighten the valve block connector 2 to the valve block through the second threaded connecting post 14, and the ED sealing ring ensures a seal with the valve block; screw the first threaded connecting post 7 of the hose connector 1 into the threaded connecting sleeve 11, and after tightening, the conical head 9 fits tightly with the conical groove 12, blocking the airflow channel and preventing gas from flowing.

[0026] Exhaust operation: When exhaust is required, use a wrench to hold the hexagonal screw 5 and rotate the hose connector 1 to separate the conical head 9 from the conical groove 12 to create a gap. The gas is then discharged sequentially through the first exhaust channel 6, the exhaust hole 8, the gap, and the second exhaust channel 15.

[0027] Maintenance and cleaning: When cleaning is required, fully unscrew the first threaded connecting post 7 and the threaded connecting sleeve 11, and directly clean the vent hole 8, the conical head 9, the conical groove 12, etc., without disassembling other parts.
