Description

Technical Field

[0001] This utility model belongs to the field of valve quick coupling technology, specifically relating to a quick coupling irrigation valve. Background Technology

[0002] Traditional irrigation valves are mostly connected to pipelines using heat fusion or adhesive bonding. These methods are cumbersome to install, time-consuming, labor-intensive, require specialized tools, and cannot be repeatedly disassembled. The drawbacks of traditional irrigation valves are particularly pronounced in situations requiring frequent adjustments to the pipeline layout.

[0003] In addition, existing quick couplings are mostly used in low-pressure, low-flow scenarios. For the higher water pressure and larger flow rates commonly found in irrigation systems, their sealing reliability and tensile strength are far from sufficient. Summary of the Invention

[0004] The quick-connect irrigation valve of this invention uses threaded connections to connect various components, giving the entire irrigation valve the advantages of good sealing, strong stability, and easy disassembly and assembly.

[0005] This utility model proposes a quick-connect irrigation valve, which includes a valve body, a front valve seat, and a valve cover. The front valve seat is fixedly connected to the valve body. The valve cover is located at both ends of the valve body. The front valve seat is fixed to the interface end of the valve body by a threaded connection. The threaded connection is used to fix and seal the valve ball. Both ends of the valve body are provided with top blocks. The valve cover is fixed to the end of the valve body by a threaded connection.

[0006] Preferably, the top block includes a left top block and a right top block; the valve cover includes a left valve cover and a right valve cover.

[0007] In any of the above embodiments, preferably, one end of the left top block abuts against the left valve cover, and the other end abuts against the front valve seat; a left retaining spring and a left-side irregular-shaped sealing ring are provided between the left top block and the left valve cover, and the left top block provides axial support for the left retaining spring and the left-side irregular-shaped sealing ring; one end of the right top block abuts against the right valve cover, and the other end abuts against the valve body; a right retaining spring and a right-side irregular-shaped sealing ring are provided between the right top block and the right valve cover, and the right top block provides axial support for the right retaining spring and the right-side irregular-shaped sealing ring. During the tightening of the valve cover, the irregular-shaped sealing ring is compressed to achieve a seal, and the retaining spring is radially contracted to achieve clamping of the pipeline.

[0008] During frequent assembly and disassembly, the fit between the front valve seat and the valve body 1 is prone to loosening. When the left top block is tightened with the front valve seat by screwing, the fit between the front valve seat and the valve body 1 becomes more secure, thus preventing loosening.

[0009] In any of the above embodiments, it is preferred that the top block has two steps on its left side, namely a first step and a second step. The first step cooperates with the retaining spring; the second step has a shrinkage allowance for the retaining spring to ensure unobstructed assembly.

[0010] In any of the above embodiments, it is preferred that the tail of the irregular sealing ring is located within the first step of the top block to compress the retaining ring, thereby clamping the pipe with the retaining ring.

[0011] In any of the above embodiments, it is preferred that the valve cover and the front end contact portion of the irregular sealing ring are provided with mutually parallel and cooperating inclined surfaces, forming a wedge-shaped structure, which can meet the requirements of smaller diameter pipes; during the tightening process of the valve cover, axial and radial pressure is generated on the irregular sealing ring, making the irregular sealing ring more reliable in sealing the pipe, while compressing the retaining spring to achieve clamping of the inserted pipe.

[0012] In addition, the cross-section of the irregular sealing ring is similar to that of an L. The beveled surface at the front end of the irregular sealing ring cooperates with the beveled surface inside the cover. During assembly, the sealing force gradually increases, and the thrust on the retaining spring gradually increases, firmly clamping the pipe. When the irregular sealing ring cooperates with the top block to the maximum extent, the vertical plane of the irregular sealing ring coincides with the top block, preventing the irregular sealing ring from deforming and not fitting tightly with the top block.

[0013] In any of the above solutions, it is preferred that the cross-section of the irregular sealing ring is L-shaped, which can simultaneously ensure the seal between the pipe and the irregular sealing ring and the top block.

[0014] In any of the above solutions, it is preferred that the retaining ring is an elastic retaining ring with a C-shaped cross-section. When the retaining ring is not under force, its cross-sectional shape is similar to a C-shaped structure. During installation and disassembly, the pipe contacts the end plane of the retaining ring, and the installation and disassembly process will not be obstructed by the tip of the retaining ring.

[0015] In any of the above embodiments, it is preferred that the valve cover is a structural component with an arc-shaped protrusion on its outer surface and internal threads, and the end of the internal thread has a section of axial plane.

[0016] The quick-connect irrigation valve of this utility model has the following advantages: the cross-section of the irregular-shaped sealing ring is similar to that of an L-shape, and the beveled front end of the irregular-shaped sealing ring cooperates with the beveled surface inside the cover. During assembly, the sealing force gradually increases, and the thrust on the retaining spring gradually increases, firmly clamping the pipe; when the irregular-shaped sealing ring is in maximum cooperation with the top block, the vertical plane of the irregular-shaped sealing ring coincides with the top block, preventing the irregular-shaped sealing ring from deforming and not fitting tightly with the top block; during operation, the connection is completed simply by inserting the pipe and tightening the cover. The entire process does not require complex processes or special tools such as hot melting or gluing, and disassembly is equally simple, greatly improving installation and maintenance efficiency; all components are self-locking through threaded connections, with strong integrity, no loose parts, good shock and impact resistance, and long service life; the huge axial pressure generated by tightening the threads forces the irregular-shaped sealing ring and retaining spring to undergo sufficient elastic deformation, forming an extremely reliable double seal of the end face and radial direction, with high pressure resistance and strong anti-fluctuation ability.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-3 The diagram shown is a structural schematic of a preferred embodiment of the quick-connect irrigation valve according to the present invention.

[0024] The quick-connect irrigation valve of this utility model includes a valve body 1, a front valve seat 2, and a valve cover 6. The front valve seat 2 is fixedly connected to the valve body 1. The valve cover 6 is located at both ends of the valve body 1. The front valve seat 2 is fixed to the interface end of the valve body 1 by a threaded connection. The threaded connection is used to fix and seal the valve ball. Both ends of the valve body 1 are provided with top blocks 3. The valve cover 6 is fixed to the end of the valve body 1 by a threaded connection.

[0025] In this embodiment, the top block 3 includes a left top block 3B and a right top block 3A; the valve cover 6 includes a left valve cover 6B and a right valve cover 6A.

[0026] In this embodiment, one end of the left top block 3B abuts against the left valve cover 6B, and the other end abuts against the front valve seat 2. A left retaining ring 4B and a left-side irregular sealing ring 5B are provided between the left top block 3B and the left valve cover 6B, with the left top block 3B providing axial support for the left retaining ring 4B and the left-side irregular sealing ring 5B. One end of the right top block 3A abuts against the right valve cover 6A, and the other end abuts against the valve body 1. A right retaining ring 4A and a right-side irregular sealing ring 5A are provided between the right top block 3A and the right valve cover 6A, with the right top block 3A providing axial support for the right retaining ring 4A and the right-side irregular sealing ring 5A. During the tightening process of the valve cover 6, the irregular sealing ring 5 is compressed to achieve a seal, and the retaining ring 4 is radially contracted to clamp the pipeline.

[0027] During frequent assembly and disassembly, the fit between the front valve seat 2 and the valve body 1 is prone to loosening. When the left top block 3B and the front valve seat 2 are tightened together by screwing, the fit between the front valve seat 2 and the valve body 1 becomes more secure, thus preventing loosening.

[0028] In this embodiment, the top block 3 has two steps on its left side, namely the first step and the second step. The first step cooperates with the retaining spring 4; the second step has a shrinkage allowance for the retaining spring 4 to ensure unobstructed assembly.

[0029] In this embodiment, the tail of the irregular sealing ring 5 is set in the first step of the top block 3 to compress the retaining spring 4, so as to achieve the clamping of the pipe by the retaining spring 4.

[0030] In this embodiment, the valve cover 6 and the front end contact parts of the irregular sealing ring 5 are both provided with mutually parallel and cooperating inclined surfaces, forming a wedge structure, which meets the requirements of smaller diameter pipes; during the tightening process of the valve cover 6, axial and radial pressure is generated on the irregular sealing ring 5, making the irregular sealing ring 5 more reliable in sealing the pipe, while squeezing the snap ring 4 to achieve clamping of the inserted pipe.

[0031] In addition, the cross-section of the irregular sealing ring is similar to that of an L-shape. The beveled surface at the front end of the irregular sealing ring mates with the beveled surface inside the cover. During assembly, the sealing force gradually increases, and the thrust on the retaining spring gradually increases, firmly clamping the pipe. When the irregular sealing ring is in maximum engagement with the top block, the vertical plane of the irregular sealing ring coincides with the top block, preventing the irregular sealing ring from deforming and becoming loosely engaged with the top block.

[0032] In this embodiment, the cross-section of the irregular sealing ring 5 is L-shaped, which can simultaneously ensure the seal between the pipe and the irregular sealing ring 5 and the top block 3.

[0033] In this embodiment, the retaining ring 4 is an elastic retaining ring with a C-shaped cross-section. When the retaining ring 4 is not under force, its cross-sectional shape is similar to a C-shaped structure. During installation and disassembly, the pipe contacts the end plane of the retaining ring 4, and the installation and disassembly process will not be obstructed by the tip of the retaining ring 4.

[0034] In this embodiment, the valve cover 6 is a structural component with an arc-shaped protrusion on its outer surface and internal threads, and the end of the internal thread has an axial plane.

[0035] The assembly process of this utility model's quick-connect irrigation valve is as follows:

[0036] First, tighten the right port of the front valve seat 2 clockwise and fix it to the left port of the valve body 1; tighten the threaded port of the right top block 3B clockwise and fix it to the left port of the front valve seat 2; tighten the threaded port of the left top block 3A clockwise and fix it to the right port of the valve body 1; tighten the threaded port of the left valve cover 6B clockwise and fix it to the left port of the front valve seat 2; tighten the threaded port of the right valve cover 6A clockwise and fix it to the right port of the valve body 1; during the tightening process, the valve cover 6 generates axial and radial forces on the irregular sealing ring 5, causing it to deform and squeeze onto the pipeline, while the radial force squeezes the snap ring 4 onto the top block 3, causing it to deform and clamp the pipeline.

[0037] In its natural state, when the pipe is inserted into the top block 3, the retaining spring 4 is compressed, and the compressed part is temporarily placed in the second step of the top block 3. During the tightening of the valve cover 6, axial and radial forces are generated on the irregular sealing ring 5, causing the irregular sealing ring 5 to deform and press against the pipe, making the sealing effect more reliable. At the same time, the retaining spring 4 is compressed to clamp the inserted pipe.

[0038] During disassembly, the valve cover 6 is loosened by turning it counterclockwise. The clamping force of the valve cover 6 on the irregular sealing ring 5 and the retaining spring 4 gradually disappears. The irregular sealing ring 5 springs back, the retaining spring 4 expands, and the pipe can be easily pulled out, achieving quick and repeatable disassembly and assembly.

[0039] It will be readily understood by those skilled in the art that the quick-connect irrigation valve of this utility model comprises any combination of the parts described in this specification. Due to space limitations and for the sake of brevity, these combinations are not described in detail here, but after reading this specification, the scope of this utility model, which consists of any combination of the parts constituted in this specification, is self-evident.
