Description

Technical Field

[0001] This application relates to the technical field of transmitters, and specifically to a connection valve for a transmitter. Background Art

[0002] A transmitter is an electrical instrument whose main function is to convert the non-electric signals output by sensors (such as physical quantities like temperature, pressure, flow rate, weight, etc.) into standard electric signals that can be recognized by a controller or a measuring instrument. The connection valve of a transmitter refers to a valve assembly that is connected to the transmitter and is used to control the flow of fluids or gases to ensure that the transmitter can accurately measure the parameters of the measured medium.

[0003] During the connection process of existing transmitters and connection valves, basically, a bolt structure is used to fixedly connect two sets of flanges at the connection point. This requires using a screwdriver to screw and tighten the screws in each hole of the flange during installation, and when disassembling or maintaining, all the screws need to be loosened one by one, making the entire disassembly and assembly process too cumbersome. Utility Model Content

[0004] In view of this, the purpose of this utility model is to solve the shortcomings in the background art and propose a connection valve for a transmitter to solve the problems existing in the prior art.

[0005] To achieve the above purpose, this utility model provides a connection valve for a transmitter, including a connection valve. A valve pipe is fixedly connected to the connection valve. One end of the valve pipe away from the connection valve is fixedly connected to a first flange. An embedding groove is formed on the outer surface of the first flange. A second flange is detachably installed on the outer surface of the first flange through a docking and positioning mechanism. A sealing ring is arranged on the outer surface of the second flange, and the outer surface of the sealing ring is movably clamped with the inner surface of the embedding groove. A transmitter is arranged on the outer surface of the second flange.

[0006] Preferably, the docking and positioning mechanism includes a fixed platform fixedly connected to the outer surface of the connection valve. A flange clamping groove is formed on the fixed platform. Through the docking and positioning mechanism, the first flange and the second flange can be quickly connected, so that the connection valve and the transmitter can be quickly docked.

[0007] Preferably, a platform shaft is fixedly connected to the outer surface of the fixed platform, and a clamping frame is rotatably connected to the outer surface of the platform shaft.

[0008] Preferably, an arc-shaped concave plate is arranged inside the clamping frame. A screw rod is threadedly connected to the inner surface of the fixed platform, and the screw rod passes through the clamping frame movably.

[0009] Preferably, a rotating abutting rod is fixedly connected to the top of the screw rod, and a rotating handle is arranged on the top of the rotating abutting rod.

[0010] Preferably, a support groove is formed on the clamping frame, and the support groove is arranged at the position where the screw on the clamping frame passes through.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. For the connection valve of the transmitter, by rotating the clamping frame and screwing the turning handle, and cooperating with the sealing ring to be embedded into the positioning groove, the connection between the first flange and the second flange can be realized, thereby indirectly connecting the transmitter and the connection valve. During the whole installation process, there is no need to screw the screws one by one like the traditional method, which greatly simplifies the operation process and significantly improves the work efficiency.

[0013] 2. For the connection valve of the transmitter, through the partial wrapping and clamping of the top parts of the two flanges by the arc-shaped concave plate inside the clamping frame, and the cooperation of the screw and the screwing rod, the stability and reliability of the connection are ensured, effectively preventing problems such as medium leakage caused by loose connection.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] Please refer to Figures 1-4, A connecting valve for a transmitter, comprising a connecting valve 1, a valve pipe 2 is fixedly communicated with the connecting valve 1, one end of the valve pipe 2 away from the connecting valve 1 is fixedly connected with a first flange 3, a clamping groove 4 is formed on the outer surface of the first flange 3, a second flange 5 is detachably installed on the outer surface of the first flange 3 through a docking clamping mechanism, a sealing ring 6 is arranged on the outer surface of the second flange 5, the outer surface of the sealing ring 6 is movably clamped with the inner surface of the clamping groove 4, and a transmitter 7 is arranged on the outer surface of the second flange 5.

[0021] Through the above technical solution, when the device is in use, only by screwing the turning handle 15, the first flange 3 and the second flange 5 can be quickly docked through the docking clamping mechanism, and the rubber sealing ring 6 is fitted into the clamping groove 4, so as to quickly connect the connecting valve 1 and the transmitter 7. During this period, no tools such as screwdrivers are needed, nor do we need to screw the screws of each hole on the flange one by one.

[0022] Specifically, the docking clamping mechanism includes a fixed platform 8 fixedly connected to the outer surface of the connecting valve 1, and a flange clamping groove 9 is formed on the fixed platform 8.

[0023] Through the above technical solution, the flange clamping groove 9 formed on the fixed platform 8 can support the two flanges, and the two flanges are also located in the flange clamping groove 9.

[0024] Specifically, a platform shaft 10 is fixedly connected to the outer surface of the fixed platform 8, and a clamping frame 11 is rotatably connected to the outer surface of the platform shaft 10.

[0025] Through the above technical solution, during the rotation of the clamping frame 11 along the platform shaft 10, the screw rod 13 needs to be separated from the fixed platform 8 to avoid hindering the rotation of the clamping frame 11.

[0026] Specifically, an arc-shaped concave plate 12 is arranged inside the clamping frame 11, a screw rod 13 is threadedly connected to the inner surface of the fixed platform 8, and the screw rod 13 passes through the clamping frame 11 movably.

[0027] Through the above technical solution, when the arc-shaped concave plate 12 clamps the first flange 3 and the second flange 5, it can further limit the two flanges to make them fit tightly.

[0028] Specifically, a rotating rod 14 is fixedly connected to the top of the screw rod 13, and a turning handle 15 is arranged on the top of the rotating rod 14.

[0029] Through the above technical solution, during the rotation of the screw rod 13, it will gradually penetrate into the fixed platform 8. During this process, the rotating rod 14 will move downward synchronously until the rotating rod 14 abuts against the supporting groove 16. At this time, if the rotating rod 14 continues to move downward, it will drive the clamping frame 11 to tighten (that is, the arc-shaped concave plate 12 further clamps the two flanges during the downward movement).

[0030] Specifically, a bracket 11 is provided with a support groove 16.

[0031] Through the above technical solution, a perforation is provided on the bracket 11 and is just below the support groove 16. After the screw rod 13 passes through the support groove 16, it can pass through the perforation.

[0032] Working principle: During the connection of the connection valve 1 and the transmitter 7, the first flange 3 at the other end of the valve pipe 2 on the connection valve 1 needs to be installed and docked with the second flange 5 on the transmitter 7. During this period, the bracket 11 needs to be rotated along the table shaft 10 to open the bracket 11. Then, the second flange 5 is brought close to and attached to the first flange 3. During this period, both groups of flanges are in the flange slot 9, and the sealing ring 6 on the second flange 5 is completely embedded in the positioning groove 4 (this design is to ensure that the connection is in a good sealing state). After that, the bracket 11 is rotated back along the table shaft 10 so that the arc-shaped concave plate 12 inside the bracket 11 is stuck on the top of the two groups of flanges and partially wraps and clamps them. Then, the screw rod 13 is passed through the perforation provided on the surface of the bracket 11, and the screw rod 13 is inserted into the top screw hole of the fixed table 8. Then, the rotary handle 15 is rotated to drive the rotary abutting rod 14 to rotate synchronously with the screw rod 13. During the rotation of the screw rod 13, it will gradually penetrate into the fixed table 8. During this period, the rotary abutting rod 14 will move down synchronously until the rotary abutting rod 14 moves down to the support groove 16. At this time, if the rotary abutting rod 14 continues to move down, it will cause the bracket 11 to tighten further, that is, the bracket 11 cooperates with the arc-shaped concave plate 12 to further clamp the two groups of flanges tightly until the first flange 3 and the second flange 5 are stably clamped, and the effect of indirectly and stably connecting the transmitter 7 and the connection valve 1 can be achieved. When disassembling and assembling, only the rotary handle 15 needs to be rotated in the reverse direction to release the restriction on the bracket 11, and the two groups of flanges can be easily separated, achieving the effect of convenient disassembly. No other tools are needed during the whole disassembly and assembly process, and there is no need to screw the screws one by one, effectively improving the disassembly and assembly efficiency.
