Description

Technical Field

[0001] This utility model relates to a pressure transmitter mounting mechanism and belongs to the field of pressure transmitters. Background Technology

[0002] A pressure transmitter is a device used to measure the pressure of liquids, gases, or vapors and convert the pressure signal into a standard electrical signal (such as a 4-20mA current signal or a 1-5V voltage signal). A sheet metal frame is a common structure for supporting pressure transmitters. The frame has a circular opening through which the external threaded tube of the pressure transmitter passes, and a limit nut is screwed on. The limit nut engages with a boss on the pressure transmitter, restricting the relative position of the pressure transmitter and the sheet metal frame. The frame is then bolted to a support. If the limit nut and the external threaded tube cannot be easily separated, it hinders the separation of the pressure transmitter from the frame, making recovery of the pressure transmitter difficult. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure transmitter mounting mechanism to solve the problems mentioned in the background art. This utility model provides a backup method for disassembling the pressure transmitter and the sheet metal frame, which facilitates the recycling of the pressure transmitter.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pressure transmitter mounting mechanism, comprising a pressure transmitter, wherein an external threaded tube is fixedly connected to the lower part of the outer surface of the pressure transmitter, a boss is sleeved on the upper end of the external threaded tube and fixedly connected to the external threaded tube and the pressure transmitter, a back sheet metal plate is provided on one side of the pressure transmitter, a side sheet metal plate is fixedly connected to one side of the back sheet metal plate, a top sheet metal plate is installed on the upper part of both side sheet metal plates, and a semi-circular groove is opened on the opposite surface of the two top sheet metal plates, the external threaded tube passes through the space formed by the two semi-circular grooves, a limiting nut located below the top sheet metal plate is threaded onto the external threaded tube, two first through holes arranged vertically are opened on one side of the back sheet metal plate, a U-shaped screw is provided on one side of the back sheet metal plate, the two ends of the U-shaped screw pass through the two first through holes respectively, and a positioning nut is threaded onto both ends of the U-shaped screw, and a pulling hole is opened on the upper surface of both top sheet metal plates, the two pulling holes being symmetrically arranged about the space formed by the two semi-circular grooves.

[0005] Furthermore, each of the two side sheet metal plates has a strip-shaped opening at the upper part of its opposite surface. A support plate is inserted into the strip-shaped opening. The support plate is positioned above the limiting nut. An end plate is connected and fixed to the end of the support plate away from the limiting nut. The end plate is in contact with the side sheet metal plate. Multiple pull rings are evenly installed on the side of the end plate away from the support plate.

[0006] Furthermore, two second through holes arranged left and right are provided on one side of the back sheet metal plate, and the second through holes have the same specifications as the first through holes.

[0007] Furthermore, a lower curved portion is connected and fixed to the lower end of the back sheet metal plate, and an upper curved portion is connected and fixed to the upper end of the back sheet metal plate. Both the lower curved portion and the upper curved portion are integrally formed with the back sheet metal plate.

[0008] Furthermore, the top sheet metal plate and the side sheet metal plate are integrally formed structures, and the side sheet metal plate and the back sheet metal plate are integrally formed structures.

[0009] Furthermore, a hexahedron is fitted onto the lower end of the externally threaded tube and fixed to the externally threaded tube, and a ball valve is threadedly connected to the lower end of the hexahedron.

[0010] The beneficial effects of this utility model are:

[0011] 1. After the external threaded tube passes through the space formed by the two semi-circular grooves, tighten the upper limit nut. Then, the upper limit nut and the boss cooperate with each other to complete the assembly of the pressure transmitter with the sheet metal frame formed by the top sheet metal plate, side sheet metal plate and back sheet metal plate. After the U-shaped screw is sleeved on the column rod and the end of the U-shaped screw passes through the back sheet metal plate, tighten the positioning nut to complete the restriction of the position of the sheet metal frame, that is, the position of the pressure transmitter is restricted.

[0012] 2. Pass the two ends of the U-shaped screw through the two first through holes respectively, so that the U-shaped screw can be fitted onto the horizontally arranged column. Pass the two ends of the U-shaped screw through the two second through holes respectively, so that the U-shaped screw can be fitted onto the vertically arranged column.

[0013] 3. When the limit nut and the external threaded pipe cannot be easily separated due to corrosion or other reasons, hooks are inserted into both pulling holes. The hooks are used to pull the top sheet metal plate. Because the top sheet metal plate is relatively thin, the distance between the two top sheet metal plates can be increased, making it easier to remove the external threaded pipe from the space formed by the two semi-circular grooves. This provides a backup method for separating the pressure transmitter and the sheet metal frame, and facilitates the recovery of the pressure transmitter.

[0014] 4. When installing the limit nut, insert the support plate into both slots and make the end plate contact the side sheet metal plate. Then, when tightening the limit nut, make the limit nut contact the support plate. At this time, there is a gap between the limit nut and the top sheet metal plate. When removing the pressure transmitter by widening the gap between the two top sheet metal plates, first pull out the support plate in the slot. At this time, the boss, the limit nut and the top sheet metal plate are all frictional resistance, thereby reducing the difficulty of widening the gap between the two top sheet metal plates.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a pressure transmitter installation mechanism, including a pressure transmitter 1, with an external threaded pipe 17 fixedly connected to the lower part of the outer surface of the pressure transmitter 1, and a hexahedron 18 fixedly connected to the lower end of the external threaded pipe 17. A ball valve 7 is threadedly connected to the lower end of the hexahedron 18, so that the ball valve 7 is connected to the container, thus completing the connection between the pressure transmitter 1 and the container, and allowing a wrench to be locked on the hexahedron 18 for easy tightening of the limit nut 16.

[0022] See Figures 1-3The upper end of the externally threaded pipe 17 is fitted with a boss 2 that is connected and fixed to the externally threaded pipe 17 and the pressure transmitter 1. A back sheet metal plate 12 is provided on one side of the pressure transmitter 1. A side sheet metal plate 8 is connected and fixed to one side of the back sheet metal plate 12. The side sheet metal plate 8 and the back sheet metal plate 12 are integrally formed. A top sheet metal plate 3 is installed on the upper end of each of the two side sheet metal plates 8. The top sheet metal plate 3 and the side sheet metal plate 8 are integrally formed. Semi-circular grooves 21 are formed on the opposite surfaces of the two top sheet metal plates 3. A threaded tube 17 passes through the space formed by two semicircular grooves 21. A limiting nut 16 located on the lower side of the top sheet metal plate 3 is threaded onto the external threaded tube 17. A lower curved part 9 is fixedly connected to the lower end of the back sheet metal plate 12, and an upper curved part 13 is fixedly connected to the upper end of the back sheet metal plate 12. Both the lower curved part 9 and the upper curved part 13 are integrally formed with the back sheet metal plate 12. Pulling holes 4 are opened on the upper surfaces of the two top sheet metal plates 3. The two pulling holes 4 are shaped around the two semicircular grooves 21. The space is symmetrically arranged so that the external threaded tube 17 passes through the space formed by the two semi-circular grooves 21. Then, the upper limit nut 16 is tightened, and the upper limit nut 16 cooperates with the boss 2 to complete the assembly of the sheet metal frame formed by the pressure transmitter 1, the top sheet metal plate 3, the side sheet metal plate 8, and the back sheet metal plate 12. The U-shaped screw 11 is sleeved on the column and the end of the U-shaped screw 11 passes through the back sheet metal plate 12. Then, the positioning nut 14 is tightened to restrict the position of the sheet metal frame, that is, the position of the pressure transmitter 1 is restricted. When the upper limit nut 16 and the external threaded tube 17 cannot be separated smoothly due to corrosion or other reasons, hooks are inserted in both pull holes 4. The hooks are used to pull the top sheet metal plate 3. Since the top sheet metal plate 3 is relatively thin, the distance between the two top sheet metal plates 3 can be increased, which makes it easier to take out the external threaded tube 17 from the space formed by the two semi-circular grooves 21. This provides a backup method for separating the pressure transmitter 1 and the sheet metal frame and facilitates the recovery of the pressure transmitter 1.

[0023] See Figures 1-3 Two vertically arranged first through holes 19 are provided on one side of the back sheet metal plate 12. A U-shaped screw 11 is provided on one side of the back sheet metal plate 12. The two ends of the U-shaped screw 11 pass through the two first through holes 19 respectively. The two ends of the U-shaped screw 11 are threaded with positioning nuts 14. Two horizontally arranged second through holes 10 are provided on one side of the back sheet metal plate 12. The second through holes 10 are the same as the first through holes 19, so that the two ends of the U-shaped screw 11 pass through the two first through holes 19 respectively, so that the U-shaped screw 11 can be sleeved on the horizontally arranged column, and the two ends of the U-shaped screw 11 pass through the two second through holes 10 respectively, so that the U-shaped screw 11 can be sleeved on the vertically arranged column.

[0024] See Figures 1-3Each of the two side sheet metal plates 8 has a slot 20 at the upper part of its opposite surface. A support plate 15 is inserted into the slot 20 and is positioned above the limit nut 16. An end plate 6 is fixed to the end of the support plate 15 away from the limit nut 16. The end plate 6 is in contact with the side sheet metal plate 8. Multiple pull rings 5 ​​are evenly installed on the side of the end plate 6 away from the support plate 15. When installing the limit nut 16, the support plate 15 is inserted into both slots 20 and the end plate 6 is in contact with the side sheet metal plate 8. When the limit nut 16 is turned, the limit nut 16 is in contact with the support plate 15. At this time, there is a gap between the limit nut 16 and the top sheet metal plate 3. When removing the pressure transmitter 1 by widening the gap between the two top sheet metal plates 3, the support plate 15 in the slot 20 is pulled out first. At this time, the boss 2, the limit nut 16 and the top sheet metal plate 3 are all frictional resistance, thereby reducing the difficulty of widening the gap between the two top sheet metal plates 3.
