Quick-release and quick-install safety connection assembly for mining three-way valve

Abstract

This utility model relates to the field of three-way valve technology and discloses a quick-release and quick-install safety connection assembly for a mining three-way valve, including: a valve end, a valve body; and a connection assembly fixedly connected between the valve end and the valve body. This quick-release and quick-install safety connection assembly for a mining three-way valve uses an annular groove on the outer wall of the mating seat to rotatably connect with an annular block, allowing the mounting seat to rotate relative to the mating seat for easy alignment with the connection seat. The threaded connection between the mounting seat and the connection seat allows for quick connection between the valve end and the valve body. As the connection seat and the mating seat gradually approach each other, the inclined surface of the upper abutment block contacts and mates with the inclined surface of the lower abutment block. Simultaneously, the upper abutment block abuts against the reinforcing block, causing the reinforcing block to slide to the left along the adjusting groove until the top of the reinforcing block is parallel to the highest point of the adjusting groove, allowing the upper abutment block to move smoothly. Then, an adjusting spring drives the reinforcing block to reset and engage in the reinforcing groove, thus making the connection between the valve end and the valve body more secure.

Description

Technical Field

[0001] This utility model relates to the field of three-way valve technology, specifically a quick-release and quick-install safety connection component for a mining three-way valve. Background Technology

[0002] The mining three-way valve is a key component of external injection single hydraulic props and two-way props. It consists of three parts: a check valve, an unloading valve, and a safety valve. The prop relies on the check valve of the three-way valve to complete the prop raising and initial support, the unloading valve to complete the prop recovery, and the safety valve to achieve constant working resistance and protect the prop from damage when it is overloaded, thus ensuring a relatively safe working environment on the coal mining face.

[0003] According to Chinese patent CN219412624U, a disassembleable three-way valve includes an upper valve body and a lower valve body. The upper end of the upper valve body is connected to the lower valve body, and the upper end of the upper valve body is provided with a connecting seat. The connecting seat has a plug inside, and the outer wall of the plug is fitted with an annular plate. The bottom of the annular plate is fixed with four equidistantly distributed limiting brackets. The limiting brackets are slidably connected to a clamping head through an internal inclined groove. The inner wall of the connecting seat has four equidistantly distributed slots. The lower end of the lower valve body is provided with a connector, and the connector has a socket inside. The upper end of the outer wall of the upper valve body has a threaded groove, and the upper valve body is threadedly connected to a threaded sleeve through the threaded groove. This design solves the problem in the existing three-way valve where, after installation, the locking block is engaged with the slot by the spring return to achieve a fixed effect. However, relying solely on the spring return pressure for locking can easily lead to loosening during use, resulting in poor sealing and affecting the use of the valve.

[0004] The aforementioned device achieves a secure connection by having the clamping head press against the inner wall of the connector and engaging with the threaded sleeve. However, this connection may loosen over time or under significant external impact or vibration, potentially leading to instability. To address this, we offer a quick-release and quick-install safety connection assembly for mining three-way valves. Utility Model Content

[0014] Compared with the prior art, this utility model provides a quick-release and quick-install safety connection assembly for a mining three-way valve, which has the following advantages:

[0015] 1. The quick-release and quick-install safety connection assembly of this mining three-way valve allows the mounting base to rotate relative to the docking seat by rotating the annular groove on the outer wall of the docking seat with the annular block. During installation, the angle can be flexibly adjusted to facilitate alignment with the connecting seat. The threaded connection between the mounting base and the connecting seat allows for quick connection between the valve end and the valve body, improving installation efficiency. At the same time, the sealing tube is clamped in the fixing groove of the left connecting frame to effectively prevent media leakage, ensuring the normal operation of the mining three-way valve and avoiding safety accidents caused by media leakage.

[0016] 2. The quick-release and quick-install safety connection assembly of this mining three-way valve allows the upper abutment block's inclined surface to contact and align with the lower abutment block's inclined surface as the connecting seat and docking seat gradually approach each other. Simultaneously, the upper abutment block abuts against the reinforcing block, causing the reinforcing block to slide to the left along the adjusting groove until the top of the reinforcing block is parallel to the highest point of the adjusting groove, allowing the upper abutment block to move smoothly. Then, the adjusting spring drives the reinforcing block to reset and lock into the reinforcing groove, thereby making the connection between the valve end and the valve body more secure.

[0025] Example 1: The quick-release and quick-install safety connection assembly for the mining three-way valve provided by this utility model, such as... Figures 1 to 5 As shown: Quick-release and quick-install safety connection assembly for a mining three-way valve, including: valve end 1, valve body 2;

[0026] And a connecting assembly 3 fixedly connected between valve end 1 and valve body 2; a mounting part 31 is fixedly connected between valve end 1 and valve body 2, and a reinforcing part 32 is connected to the mounting part 31.

[0027] The mounting part 31 includes a docking seat 311 fixedly connected to the left side of the valve body 2. The outer wall of the docking seat 311 has an annular groove 312. An annular block 313 is rotatably connected to the inner surface of the annular groove 312. The outer wall of the annular block 313 is fixedly connected to a mounting seat 314. The inner wall of the left end of the mounting seat 314 is threadedly connected to a threaded groove 315 on the outer wall of the connecting seat 316. A right connecting frame 317 is provided inside the mounting seat 314. A sealing tube 318 is fixedly connected to the left side of the right connecting frame 317. The left end of the sealing tube 318 is engaged with the inner surface of a fixing groove 310. The fixing groove 310 is located on the right side of a left connecting frame 319. The outer wall of the right connecting frame 317 is fixedly connected to the inner wall of the docking seat 311. The outer walls of the left connecting frame 319 are respectively fixedly connected to the inner walls of the connecting seat 316.

[0028] In this embodiment, the outer wall of the sealing tube 318 is in contact with the bottom surface of the lower abutment block 321, which can effectively fill the gap between the two and form a sealing barrier to prevent the medium from leaking from the connection part.

[0029] Example 2: Based on Example 1, the quick-release and quick-install safety connection assembly for the mining three-way valve provided by this utility model, such as... Figures 1 to 5As shown: The reinforcing part 32 includes a lower abutment block 321 fixedly connected to the inner wall of the connecting seat 316. The left side of the lower abutment block 321 is fixedly connected to the right side of the left connecting frame 319. An adjustment groove 322 is provided on the inclined surface of the lower abutment block 321. A stabilizing rod 323 is fixedly connected to the inner surface of the adjustment groove 322. An adjusting spring 324 is sleeved on the outer wall of the left end of the stabilizing rod 323. The left end of the adjusting spring 324 is fixedly connected to the inner left side of the adjustment groove 322. A sliding block 325 is fixedly connected to the right end of the adjusting spring 324. The inner wall of the sliding block 325 is sleeved on the outer wall of the stabilizing rod 323. A reinforcing block 326 is fixedly connected to the top of the sliding block 325. The top of the reinforcing block 326 is engaged with the inner surface of the reinforcing groove 328. The reinforcing groove 328 is opened on the inclined surface of the upper abutment block 327. The right side of the upper abutment block 327 is fixedly connected to the left side of the right connecting frame 317.

[0030] In this embodiment, the inclined surface of the lower abutment block 321 is provided corresponding to the inclined surface of the upper abutment block 327.

[0031] Furthermore, the adjustment groove 322 is trapezoidal, and the highest point of the adjustment groove 322 is parallel to the top surface of the reinforcing block 326, so that the reinforcing block 326 can move stably along the adjustment groove 322, and the upper abutment block 327 can move smoothly.

[0032] Furthermore, the top left end of the upper abutment block 327 is in close contact with the inner wall of the connecting seat 316, which further enhances the overall stability of the connecting assembly 3.

[0033] In actual operation, when this device is in use, the annular groove 312 on the outer wall of the docking seat 311 is rotatably connected to the annular block 313, allowing the mounting seat 314 to rotate relative to the docking seat 311. During installation, the angle can be flexibly adjusted to facilitate alignment with the connecting seat 316. Then, through the threaded connection between the mounting seat 314 and the connecting seat 316, the connection between the valve end 1 and the valve body 2 can be quickly completed, improving installation efficiency. At the same time, the sealing tube 318 is snapped into the fixing groove 310 of the left connecting frame 319, which can effectively prevent media leakage, ensure the normal operation of the mining three-way valve, and avoid safety accidents caused by media leakage.

[0034] Simultaneously, as the connecting seat 316 and the docking seat 311 gradually approach each other, the inclined surface of the upper abutment block 327 contacts and docks with the inclined surface of the lower abutment block 321. At the same time, the upper abutment block 327 abuts against the reinforcing block 326, causing the reinforcing block 326 to slide to the left along the adjusting groove 322 until the top of the reinforcing block 326 is parallel to the highest point of the adjusting groove 322, so that the upper abutment block 327 can move smoothly. Then, the adjusting spring 324 drives the reinforcing block 326 to reset and lock into the reinforcing groove 328, thereby making the connection between the valve end 1 and the valve body 2 more secure.

[0035] When separation is required, the valve body 2 rotates, and the upper abutment block 327 rotates through the right connecting bracket 317, so that the reinforcing block 326 is squeezed and gradually detaches from the reinforcing groove 328. At the same time, the upper abutment block 327 and the lower abutment block 321 are misaligned. At this time, the mounting seat 314 is rotated in the opposite direction, so that the mounting seat 314 is detached from the connecting seat 316, thereby completing the separation of the valve end 1 from the valve body 2.
