Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, and in particular to a fixed sprinkler irrigation device with strong sealing performance. Background Technology

[0002] In the field of agricultural irrigation, stationary irrigation equipment is widely used due to its convenient installation and stable operation. Its core lies in achieving stable water delivery and precise control through pipeline connection structures. However, existing equipment often faces the problem of insufficient sealing during long-term use: on the one hand, the connection between the pipeline and the valve body often uses a single seal, which is prone to leakage under high-pressure water flow or frequent switching, leading to water waste; on the other hand, farmland irrigation water often contains impurities such as silt, which cause continuous erosion and wear on the valve core inside the valve body, not only reducing sealing performance but also shortening the service life of the equipment.

[0003] Meanwhile, the traditional connection structure is cumbersome to disassemble and maintain, and the threaded connection lacks a targeted sealing design, making it prone to leakage due to installation errors or loosening after long-term use. Furthermore, the mating joint between the valve core and valve stem 36 often suffers from gap leakage during valve core rotation due to its simple sealing structure. Therefore, developing a fixed irrigation equipment connection structure with strong sealing performance, wear resistance, and easy maintenance has become a key requirement for improving agricultural irrigation efficiency and reducing operating costs.

[0004] The purpose of this invention is to provide a fixed sprinkler irrigation device with strong sealing performance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a three-way connecting pipe, a connecting pipe threaded at the top of the three-way connecting pipe, a reinforced sealing valve body threaded at the top of the connecting pipe, and a water outlet pipe at the top of the reinforced sealing valve body.

[0006] As a preferred embodiment of this utility model, the reinforced sealing valve body includes a ball valve core, a valve stem is provided on one side of the ball valve core, a handle is provided at the top of the valve stem, the ball valve core is disposed in a sealing clamp kit, a first sealing buffer is provided in both ports of the sealing clamp kit, a second sealing buffer is provided on the valve stem, the second sealing buffer is disposed in the sealing clamp kit and fits against the outer wall of the ball valve core.

[0007] As a preferred embodiment of this utility model, the sealing jacket includes an upper jacket and a lower jacket. The bottom of the upper jacket is provided with a mating groove, and the top of the lower jacket is provided with a mating protrusion. The mating protrusion is inserted into the mating groove. Several fitting reinforcing ribs are provided on the inner walls of both the lower jacket and the upper jacket, and a mud and sand chamber is formed between two adjacent fitting reinforcing ribs. The ball valve core is disposed between the several fitting reinforcing ribs.

[0008] As a preferred embodiment of the present invention, the first sealing buffer includes a compression sealing pad, the top of which is provided with a first mounting groove, and a sealing ring is provided in the first mounting groove.

[0009] As a preferred embodiment of this utility model, the second sealing buffer includes a pressure ring sandwiched between the upper and lower jackets. A second compression sealing pad is provided in front of the pressure ring. The second compression sealing pad is fitted onto the outer wall of the ball valve core. A second mounting groove is provided on the back of the second compression sealing pad. A third mounting groove is provided on the front of the pressure ring. A third sealing ring is provided between the second compression sealing pad and the pressure ring. The third sealing ring is located between the second mounting groove and the third mounting groove.

[0010] As a preferred embodiment of this utility model, both the first and second extrusion sealing gaskets are provided with fitting arc grooves on the side near the ball valve core.

[0011] As a preferred embodiment of this utility model, a Y-shaped sealing gasket is fitted at the bottom of the water outlet pipe, and a conical outward flange is provided on the outer side of the bottom of the Y-shaped sealing gasket, and the conical outward flange is pressed against the inner wall of the valve body.

[0012] As a preferred embodiment of this utility model, a sealing ring is provided at the bottom of the threads at both the upper and lower ends of the connecting pipe.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1. This utility model forms a multi-layered sealing protection through a sealing ring + sealing gasket + fitting structure. It includes a sealing ring one at the pipe thread, a first sealing buffer (compressed sealing gasket one + sealing ring two) at the sealing jacket port, a second sealing buffer (compressed sealing gasket two + sealing ring three) at the connection between the valve stem and the valve core, and a Y-shaped sealing gasket (conical outward-flaring compression valve shell inner wall) at the bottom of the water outlet pipe. This comprehensively seals off potential water leakage from the threaded connection and valve body port to the moving parts of the valve core. It is especially suitable for high-pressure water flow scenarios during irrigation, avoiding water waste caused by leakage.

[0014] 2. The sealing jacket of this utility model adopts an upper and lower jacket docking structure, combined with the fitting reinforcing ribs on the inner wall. It can not only firmly clamp the ball valve core, but also temporarily store the mud and sand in the water flow through the mud and sand chamber formed by the adjacent reinforcing ribs, reducing the direct scouring and wear of mud and sand on the valve core. The mud and sand can be flushed away when the valve is opened next time. This method extends the service life of the equipment and is suitable for irrigation environments with many impurities, such as farmland.

[0015] 3. The compression sealing gaskets one and two of this utility model are designed with fitting arc grooves on the side near the valve core, which can fit tightly with the outer wall of the valve core, and can maintain good sealing performance even when the valve core is rotating; the conical outward flange of the Y-shaped sealing gasket can adapt to the slight deformation of the connection part by compressing and fitting the inner wall of the valve shell, further improving the sealing reliability and ensuring that the equipment can still seal stably under dynamic working conditions such as long-term fixed installation and frequent switching.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] like Figure 1-12 As shown, the present invention proposes a fixed sprinkler irrigation device with strong sealing performance, which includes a three-way connecting pipe 1, the top of which is connected to the connecting pipe 2 by a thread, the top of the connecting pipe 2 is connected to the reinforcing sealing valve body 3 by a thread, and the top of the reinforcing sealing valve body 3 is directly connected to the water outlet pipe 4, forming a complete water flow path. In the design of the reinforced sealing valve body 3, a ball valve core 35 is used as the control core, with a valve stem 36 extending from one side. A handle 37 is installed at the top of the valve stem 36. By rotating the handle 37, the valve stem 36 and the ball valve core 35 can be driven to rotate synchronously, thereby realizing convenient control of pipeline opening and closing. In order to improve the sealing performance, the ball valve core 35 is wrapped inside the sealing jacket 31. A first sealing buffer 34 is installed at both ends of the sealing jacket 31. At the same time, a second sealing buffer 38 is sleeved on the valve stem 36. The second sealing buffer 38 is located inside the sealing jacket 31 and is tightly fitted with the outer wall of the ball valve core 35, forming multiple sealing protections. The sealing jacket 31 adopts a split structure, consisting of an upper jacket 310 and a lower jacket 312. The bottom of the upper jacket 310 is provided with a mating groove 311, and the top of the lower jacket 312 is provided with a corresponding mating protrusion 313. The mating protrusion 313 is inserted into the mating groove 311 to achieve precise splicing of the two. It is worth noting that the inner walls of the upper jacket 310 and the lower jacket 312 are distributed with multiple fitting reinforcing ribs 32. A mud and sand chamber 33 is formed between adjacent reinforcing ribs, which can temporarily accommodate a small amount of mud and sand flowing through, reducing direct wear on the ball valve core 35. The ball valve core 35 is placed precisely between these reinforcing ribs, and the overall structural stability is improved with the support of the reinforcing ribs. The structure of the first sealing buffer 34 includes a compression sealing pad 340, with a first mounting groove 342 on its top and a sealing ring 341 installed in the groove. Through the synergistic effect of the compression sealing pad 340 and the sealing ring 341, the sealing effect of both sides of the sealing jacket 31 is effectively enhanced. The second sealing buffer 38 is composed of a pressure ring 380, a second compression sealing gasket 381, and a third sealing ring 384. The pressure ring 380 is sandwiched between the upper jacket 310 and the lower jacket 312, and the second compression sealing gasket 381 in front of it is in close contact with the outer wall of the ball valve core 35. The second compression sealing gasket 381 has a second mounting groove 382 on its back, and the pressure ring 380 has a corresponding third mounting groove 383 on its front. The third sealing ring 384 is embedded between these two mounting grooves. The three components work together to enhance the sealing performance at the connection between the valve stem 36 and the ball valve core 35. In addition, the compression sealing gasket 340 and compression sealing gasket 381 are both designed with fitting arc grooves 39 on the side near the ball valve core 35, so that they fit more tightly with the outer wall of the ball valve core 35; the bottom of the outlet pipe 4 is fitted with a Y-shaped sealing gasket 40, and the tapered outer flange 41 of its bottom outer side is pressed against the inner wall of the valve body 30, further improving the sealing performance of the connection between the outlet pipe 4 and the valve body; a sealing ring 20 is also provided at the bottom of the threads at both ends of the connecting pipe 2 to enhance the leak-proof effect of the threaded connection.
