A valve structure that is easy to install

Abstract

This utility model provides a valve structure that is easy to install, relating to the field of valve installation technology. It includes a valve body, with connecting pipes connected to both ends of the valve body. A flange ring is installed on each valve port and the corresponding connecting pipe port. A sealing ring is fitted onto the outer wall of the connecting pipe. The inner wall of the sealing ring has an L-shaped cross-section, with one inner wall slidingly connected to the outer edge of the flange ring, and the other inner wall fixedly fitted with a pin that passes through a bolt hole on the flange ring surface. This sealing ring and pin replace the traditional initial positioning with multiple bolts. The pin directly passes through the flange ring bolt hole to achieve initial fixation. An arc-shaped strip can work with an annular groove to simultaneously clamp all pins, eliminating the need to apply force to each bolt individually. A spur-toothed ring is located outside the valve port; moving the spur-toothed ring drives the sliding frame to tighten the flange ring via a screw drive, avoiding the difficulty of applying force to bolts in a confined space and reducing workload.

Description

Technical Field

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

[0002] In order to ensure installation efficiency during valve installation, an existing valve structure (publication number CN223375208U) facilitates installation. First, a flange joint is connected to one end of the inlet pipe. The first movable ring is pushed to its side near the flange joint connection surface via a first groove at the top of the inlet pipe and a first limiting slider on the inner wall of the first movable ring. Simultaneously, this moves the first semi-circular support plate to the bottom of the flange joint, where it is in a supporting position. At this point, the installer places the flange end to be connected onto the top of the first semi-circular support plate, ensuring that the pre-drilled mounting holes align correctly. Then, with one hand assisting in positioning, the other hand rotates the first tightening bolt, causing the first clamping plate and the first clamping claw to move towards the back side of the flange connection face until the flange is clamped and fixed to the flange joint. At this point, the worker can screw the two reserved mounting holes on the left and right sides of the flange joint and tighten them initially. Then, loosen the first clamping claw so that its lowest point on the horizontal plane is above the top surface of the flange joint. Then, move the first movable ring towards the valve body side along the first sliding groove so that the flange joint is fully exposed, making it easier for the installer to tighten the remaining reserved mounting holes. The operation method for connecting the flange joint at the outlet pipe end is the same as that for the inlet pipe joint.

[0003] However, existing technology requires the use of bolts when fixing flanges and flange joints. The number of bolts used is large, and some bolts are located at the lower end of the valve body, where the operating space is limited. The large number of bolts leads to long installation time, and the limited operating space at the lower end of the valve body makes it difficult for workers to apply force, further increasing the difficulty of the operation. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a valve structure that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a valve structure that is easy to install, comprising a valve body, wherein both ends of the valve body are connected to connecting pipes, and a flange ring is installed on each valve port of the valve body and the corresponding pipe port. A sealing ring is fitted on the outer wall of the connecting pipe. The inner side wall of the sealing ring has an L-shaped cross-section, and one inner side wall of the sealing ring is slidably connected to the outer edge of the flange ring, while the other inner side wall is fixedly installed with a pin that passes through a bolt hole on the surface of the flange ring. An annular groove is formed on the circumferential surface of the pin away from the sealing ring. A sliding frame is fitted on the surface of the valve body. The bottom edge of the outer edge of the sliding frame extends downward and is fixedly installed with an extension seat. Two symmetrically arranged arc-shaped strips are rotatably connected to the extension seat. The swing edges of the two arc-shaped strips are threadedly connected to bolts that pass through the top edge of the outer edge of the sliding frame, and the two arc-shaped strips are inserted into the inner wall of the annular groove.

[0006] Preferably, a sealing ring is installed on both the inner and outer rings of the other inner side wall of the sealing ring, and a sealing gasket is installed on the inner ring of the opposite face of two adjacent flange rings.

[0007] Preferably, a plurality of guide rails are fixedly installed on the outer surface of the valve plate ladder valve port. The guide rails are arranged parallel to the central axis of the valve body valve port, and the inner side of the sliding frame extends inward and is inserted into the inner wall of the guide rail.

[0008] Preferably, a screw rod is rotatably connected inside the guide rail, which is parallel to the central axis of the valve body and extends through the sliding frame box. A spur gear is fixedly installed on the end of the screw rod facing the valve body and valve seat.

[0009] Preferably, the valve body is fitted with a spur gear ring on the valve port, the inner ring of the spur gear ring is rotatably connected to the guide rail surface, and the inner tooth surface of the spur gear ring meshes with several spur gears at the valve port on the same side.

[0010] Preferably, two arc-shaped slide rails are symmetrically fixedly installed at the top edge of the outer side of the sliding frame. The two arc-shaped slide rails correspond to the swing ends of the two arc-shaped bars, and the swing ends of the arc-shaped bars extend outward to form a T-shaped rotating body and are slidably connected to the inner wall of the adjacent arc-shaped slide rail.

[0011] Preferably, a screw is provided through the sliding frame, and the screw is threadedly connected to the outer surface of the valve port of the valve body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a sealing ring and pins are used to replace the traditional initial positioning of multiple bolts. The pins can be directly passed through the bolt holes of the flange ring to achieve initial fixation, without the need to screw in the bolts one by one, which greatly reduces the number of bolts used and shortens the time spent in the early stage of installation. The arc strip can work with the annular groove to simultaneously clamp all the pins, without the need to apply force to each bolt individually. The straight toothed ring is located on the outside of the valve port, and the operating space is not restricted by the lower end of the valve body. Moving the straight toothed ring can drive the sliding frame to tighten the flange ring through the screw drive, avoiding the difficulty of applying force to the bolts in a narrow space and reducing the labor intensity.

[0014] 2. In this utility model, the sliding bracket is threadedly connected to the valve body by screws, which can effectively fix the position of the sliding bracket, prevent the sliding bracket from loosening due to vibration during long-term use, and ensure the stable connection state of the flange ring.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, an easy-to-install valve structure includes a valve body 1. Both valve ports of the valve body 1 are connected to connecting pipes 2, and a flange ring 17 is installed on each valve port of the valve body 1 and the corresponding pipe port of the connecting pipe 2. A sealing ring 3 is sleeved on the outer wall of the connecting pipe 2. A sealing ring 7 is installed on the inner and outer rings of the other inner side wall of the sealing ring 3. A sealing gasket 8 is installed on the inner ring of the opposite face of two adjacent flange rings 17. The sealing ring 7 and the sealing gasket 8 can ensure the sealing of the inner side of the sealing ring 3.

[0023] The inner wall of the sealing ring 3 has an L-shaped cross section, and one inner wall of the sealing ring 3 is slidably connected to the outer edge of the flange ring 17, while the other inner wall is fixedly installed with a pin 12 that passes through the bolt 15 hole on the surface of the flange ring 17. By passing several pins 12 through the aligned bolt 15 holes on the two flange rings 17, the initial position of the mating flange rings 17 can be fixed. Furthermore, by using the inner wall of the sealing ring 3 to fit against the outer edges of the two mating flange rings 17, the relative position of the two mating flange rings 17 can be further fixed.

[0024] An annular groove 13 is formed on the circumferential surface of the pin 12 away from the sealing ring 3. A sliding bracket 10 is fitted onto the surface of the valve body 1. An extension seat 16 is fixedly installed on the bottom edge of the outer side of the sliding bracket 10. Two symmetrically arranged arc-shaped strips 9 are rotatably connected to the extension seat 16. Bolts 15, which penetrate the top edge of the outer side of the sliding bracket 10, are threaded onto the swing edges of the two arc-shaped strips 9. The two arc-shaped strips 9 are inserted into the inner wall of the annular groove 13. After the pin 12 passes through the aligned bolt holes 15 on the two flange rings 17, it swings along the two arc-shaped strips 9 to the desired position. Figure 1 In the state shown, the two arc-shaped bars 9 can be simultaneously inserted into the annular grooves 13 on the surface of all the pins 12 on the sealing ring 3. At this time, the two arc-shaped bars 9 are fixed in position by bolts 15 passing through the sliding frame 10 and threadedly connected to the surface of the arc-shaped bars 9. Then, by sliding the sliding frame 10 on the surface of the valve body 1, the pins 12 can be pulled to drive the sealing ring 3 and the flange ring 17 on the connecting pipe 2 to the flange ring 17 that is tightly attached to the surface of the valve body 1.

[0025] Several guide rails 6 are fixedly installed on the outer surface of the valve plate ladder valve port. The guide rails 6 are arranged parallel to the central axis of the valve port of the valve body 1, and the inner side of the sliding frame 10 extends inward and is inserted into the inner wall of the guide rails 6. A screw 14, which is parallel to the central axis of the valve port of the valve body 1 and is threaded through the extension of the sliding frame 10, is rotatably connected inside the guide rails 6. A spur gear 5 is fixedly installed on the end of the screw 14 facing the valve seat of the valve body 1. A spur gear ring 4 is sleeved on the valve port of the valve body 1. The inner ring of the spur gear ring 4 is rotatably connected to the surface of the guide rails 6, and the inner tooth surface of the spur gear ring 4 is meshed with several spur gears 5 at the valve port on the same side. In actual use, by turning the spur gear ring 4, the meshing spur gears 5 can be driven to rotate the corresponding screw 14. By using the threaded connection between the screw 14 and the extension of the sliding frame 10, the sliding frame 10 can slide relative to the flange ring 17 and along the central axis of the valve port of the valve body 1.

[0026] Two arc-shaped slide rails 11 are symmetrically fixedly installed on the top edge of the outer side of the sliding frame 10. The two arc-shaped slide rails 11 correspond to the swing ends of the two arc-shaped bars 9 respectively. The swing ends of the arc-shaped bars 9 extend outward to form a T-shaped rotating body and are slidably connected to the inner wall of the adjacent arc-shaped slide rail 11. The arc-shaped bars 9 ensure that the two arc-shaped bars 9 are stable and do not wobble during the swing opening and closing process. A screw 18 is installed through the sliding frame 10. The screw 18 is threaded to the outer surface of the valve port of the valve body 1. By using the screw 18 to pass through the sliding frame 10 and threaded to the surface of the valve body 1, the relative position of the sliding frame 10 and the valve body 1 can be fixed, and the surface sliding frame 10 can be loosened.

[0027] The method of using this utility model is as follows:

[0028] Place the valve body 1 between the two connecting pipes 2, adjust the position of the valve body 1 so that the flange ring 17 of the connecting pipe 2 is aligned with the flange ring 17 of the valve port of the valve body 1, separate the two arc strips 9 to achieve misalignment between the arc strips 9 and the pin 12, slide the sealing ring 3 on the connecting pipe 2 so that the inner pin 12 passes through the aligned bolt 15 holes on the two flange rings 17, and achieve the initial position fixation of the flange rings 17.

[0029] Adjust the position of the sliding bracket 10 so that the two arc-shaped bars 9 on the extension seat 16 swing to the position corresponding to the annular groove 13 of the pin 12. Swing the arc-shaped bars 9 so that their inner sides are engaged in the annular grooves 13 of all the pins 12. Insert bolts 15 into the swing ends of the two arc-shaped bars 9 so that the bolts 15 pass through the top edge of the outer edge of the sliding bracket 10 and are threadedly connected to the arc-shaped bars 9 to fix the position of the arc-shaped bars 9.

[0030] The spur ring 4 outside the valve port of the valve body 1 is moved, and the spur ring 4 and the spur gear 5 are meshed and driven to rotate the screw 14 inside the guide rail 6. The screw 14 is connected to the inner extension of the sliding frame 10 by the thread, so that the sliding frame 10 slides along the guide rail 6 away from the connecting pipe 2. Then, the pin 12 is pulled by the arc strip 9 and the annular groove 13. Then, the pin 12 is pulled to pull the sealing ring 3 and the flange ring 17 of the connecting pipe 2, so that they are tightly attached to the flange ring 17 of the valve body 1.

[0031] A screw 18 is passed through the sliding bracket 10 to make the screw 18 threadedly connected to the outer surface of the valve port of the valve body 1, thereby fixing the position of the sliding bracket 10, preventing loosening, and completing the docking.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
