Description

Technical Field

[0001] This utility model relates to the field of valve installation technology, and in particular to a valve installation structure. Background Technology

[0002] In agricultural irrigation, it is sometimes necessary to open branch water pipes to irrigate agricultural products by bypassing the main irrigation water pipe. The conventional way to open branch water pipes on the surface of the main water pipe is to cut the main water pipe and install a three-way valve, a stop valve and a branch water pipe. However, this method requires a professional plastic water pipe welder and the operation steps are cumbersome and the installation is too time-consuming.

[0003] To address this, Chinese utility model patent CN 221857674 U discloses a valve installation structure, including a valve body. The lower end of the valve body is provided with an assembly structure that can be integrated with a water pipe. The assembly structure includes a first arc-shaped clamp and a second arc-shaped clamp, and a water conveying structure is provided between the first arc-shaped clamp and the valve body. In this valve installation structure, the first and second arc-shaped clamps are placed on the surface of the water pipe, and then bolts are used to fix the first fixing plate and the second arc-shaped clamp to the surface of the water pipe. Next, the valve body is screwed into a threaded cylinder. At this point, a rivet will puncture the surface of the water pipe. The rivet is then removed from the surface of the guide tube, and the valve body and the threaded cylinder are then installed together. Water from the water pipe flows into the valve body along the guide tube. Compared to existing technologies, this device utilizes an assembly structure to integrate with the water pipe, and then integrates the water conveying structure with the first arc-shaped clamp, thus allowing for the rapid installation of a bypass water pipe on the surface of the water pipe.

[0004] However, when installing a bypass water pipe later, even if the main valve is shut off, a certain amount of water will still remain in the main water pipe. When the surface of the main water pipe is punctured and the valve body is removed, the water remaining in the main water pipe will spray out from the hole, making it more troublesome to reinstall the valve body and also causing a waste of water resources. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, this utility model provides a valve installation structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a valve installation structure, including a first arc-shaped clamping plate and a second arc-shaped clamping plate. An arc-shaped sealing gasket is provided on the inner ring surface of the first arc-shaped clamping plate. A ball valve assembly is installed on the first arc-shaped clamping plate. The ball valve assembly includes a valve body. A sealing tube is installed at the top of the valve body. A connecting screw is movably installed inside the sealing tube. A piston plate is provided at the bottom end of the connecting screw. A tie is fixedly connected to the bottom end of the piston plate. A connecting tube is fixedly installed at the bottom end of the valve body. A guide hole matching the tie is opened at the axis of the connecting tube.

[0007] Furthermore, the valve body has a first threaded portion at its top end, the sealing tube is fitted and installed at the first threaded portion, the sealing tube has a first screwing portion around its periphery, the sealing tube has a threaded hole at the center of its top end that matches the connecting screw, the connecting screw is fitted and installed in the threaded hole, and the connecting screw has a screwing table at its top end.

[0008] Furthermore, a sealing ring is fixedly installed on the side wall of the piston disc, the sealing ring is tightly attached to the inner side wall of the valve body, and a cone is provided at the bottom end of the connecting pipe.

[0009] Furthermore, the bottom end of the valve body is provided with a second threaded portion, the top periphery of the valve body is provided with a second screwing portion, and a threaded cylinder matching the second threaded portion is fixedly installed at the top center of the first arc-shaped clamp.

[0010] Furthermore, a valve ball is fitted into the middle of the inner cavity of the valve body, a valve stem is movably mounted on the valve body, the valve stem is fixedly connected to the valve ball, and a handle is fixedly mounted on the end of the valve stem away from the valve ball.

[0011] The beneficial effects of this utility model are that, through the design of a sealing tube installed at the top of the valve body, by rotating the connecting screw to the bottom limit position, the rivet is inserted into the guide hole. When the valve body is installed on the first arc-shaped clamp, the rivet, together with the connecting tube, punctures the outer wall of the water pipe. Then, by rotating the connecting screw counterclockwise, the rivet is dislodged from the guide hole, and the water flowing into the valve body is isolated below the piston disc. When the rivet moves into the sealing tube, the ball valve assembly is closed, thereby preventing the water in the main water pipe from continuing to flow out. Afterwards, the sealing tube is removed and an external branch water pipe is installed to complete the installation of the bypass water pipe, thus making the installation of the bypass water pipe time-saving and labor-saving, and reducing the waste of water resources.

[0019] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0020] according to Figure 1-5 As shown, a valve mounting structure includes a first arc-shaped clamping plate 1 and a second arc-shaped clamping plate 2. An arc-shaped sealing gasket 3 is provided on the inner ring surface of the first arc-shaped clamping plate 1. A ball valve assembly is fitted on the first arc-shaped clamping plate 1. The ball valve assembly includes a valve body 4. A valve ball 10 is fitted in the middle of the inner cavity of the valve body 4. A valve stem 11 is movably mounted on the valve body 4. The valve stem 11 is fixedly connected to the valve ball 10. A handle 12 is fixedly mounted on the end of the valve stem 11 away from the valve ball 10. A sealing tube 5 is fitted on the top of the valve body 4. A connecting screw 6 is movably mounted inside the sealing tube 5. A piston disc 61 is welded to the bottom end of the connecting screw 6. A tie 62 is welded to the bottom end of the piston disc 61. A connecting pipe 7 is fixedly mounted and welded to the bottom end of the valve body 4. A guide hole 71 matching the tie 62 is opened at the axis of the connecting pipe 7.

[0021] In this embodiment, the top of the valve body 4 is provided with a first threaded portion 41. The sealing tube 5 is installed at the first threaded portion 41 through a threaded fit. The outer periphery of the sealing tube 5 is provided with a first screwing portion 51. The sealing tube 5 is connected to a tool such as a wrench through the first screwing portion 51, thereby fastening the sealing tube 5 to the top of the valve body 4. A threaded hole 52 matching the connecting screw 6 is opened at the center of the top of the sealing tube 5. The connecting screw 6 is installed in the threaded hole 52 through a threaded fit. The top of the connecting screw 6 is provided with a screwing table 63. The connecting screw 6 is connected to the valve body 4 through a screwing table 63. The screwing table 63 can be connected to tools such as wrenches so that the user can rotate the connecting screw 6. The user rotates the connecting screw 6 to move the rivet 62 between the valve body 4 and the sealing tube 5. The bottom end of the valve body 4 is provided with a second threaded part 42, and the top periphery of the valve body 4 is provided with a second screwing part 43. The top center of the first arc-shaped clamp 1 is fixedly installed with a threaded cylinder 9 that matches the second threaded part 42. The valve body 4 is connected to the threaded cylinder 9 through the second threaded part 42, so that the valve body 4 can be fastened to the first arc-shaped clamp 1.

[0022] In this embodiment, a sealing ring 8 is fixedly installed on the side wall of the piston disc 61. The sealing ring 8 is in close contact with the inner side wall of the valve body 4. When the rivet 62 is removed, the water is isolated below the sealing ring 8 by the action of the piston disc 61 and the sealing ring 8, thereby preventing the water from spraying out. The bottom end of the connecting pipe 7 is provided with a truncated cone 72, which is flush with the bottom conical surface of the rivet 62. The truncated cone 72 allows the connecting pipe 7 to be easily inserted into the water pipe.

[0023] In use, the first arc-shaped clamp 1 and the second arc-shaped clamp 2 are first securely installed on the outside of the water pipe. After rotating the connecting screw 6 to its bottom limit position, the valve body 4 is fitted onto the threaded cylinder 9. At this time, the anchor bolt 62 is inserted into the guide hole 71. When the valve body 4 is fitted onto the threaded cylinder 9, the anchor bolt 62, together with the connecting pipe 7, punctures the outer wall of the water pipe. Then, the connecting screw 6 is rotated counterclockwise to disengage the anchor bolt 62 from the guide hole 71, and the water in the water pipe will flow through the guide hole 71. The flow hole 71 enters the valve body 4. Under the action of the sealing ring 8, the water is isolated below the piston disc 61. When the rivet 62 moves into the sealing tube 5, the handle 12 is turned so that the valve ball blocks the inner cavity of the valve body 4, thereby closing the ball valve assembly to prevent the water in the pipe from spraying out. Then, the sealing tube 5 is removed from the valve body 4, and the external branch water pipe is installed on the valve body 4 to complete the installation of the bypass water pipe. This makes the process of installing the bypass water pipe time-saving and labor-saving, and can reduce the waste of water resources.
