Description

Technical Field

[0001] The utility model relates to the technical field related to pressure transmitters, in particular to a multi-directional pressure transmitter. Background Art

[0002] Pressure transmitters are used to measure the liquid level, density and pressure of liquids, gases or steam, and then convert the pressure signal into an analog electrical signal output; pressure transmitters mainly include capacitive pressure transmitters and diffused silicon pressure transmitters, ceramic capacitive pressure transmitters, strain gauge pressure transmitters, etc.

[0003] Pressure transmitters are usually installed on pipelines. In a single pipeline environment with sufficient space reserved, the installation of pressure transmitters usually does not cause major problems. However, when installed in a complex pipeline environment with limited space, the messy pipeline directions and narrow space bring great troubles to the installation of pressure transmitters. Especially when multiple pressure transmitters need to be installed in a narrow, parallel pipeline environment, the placement of multiple pressure transmitters may hinder each other, and the surrounding environment may also hinder the installation of the pressure transmitter.

[0004] The existing bracket has a complex structure and is not easy to disassemble and install, which makes it inconvenient to install the pressure transmitter and has poor stability, which in turn affects the use of the pressure transmitter. In addition, many brackets are almost all made of sheet metal processing, which requires special molds, occupies a lot of funds, and has high manufacturing costs. At the same time, after the existing bracket is installed, the position of the pressure transmitter head is fixed and cannot be adjusted, which makes it very inconvenient to check, maintain and calibrate the head, increasing the workload of the staff.

[0021] See Figures 1 to 4As shown, a multi-directional pressure transmitter includes a main body 15. The main body 15 is a prior art and a mature pressure transmitter is selected to work.

[0022] In actual use, the main body 15 is generally connected to different pipes for work, including various horizontal and vertical pipes. Therefore, the main body 15 needs to adjust different angles according to the use conditions. In this embodiment, the conventional shape of the main body 15 is cylindrical. A collar 22 is rotatably installed on the peripheral wall of the main body 15. The collar 22 is sleeved on the main body 15. At the same time, a stud 11 is connected to the collar 22. The stud 11 can be connected to the pipe through a connecting piece such as a connecting buckle or a connecting ring. At the same time, the stud 11 and the connecting piece can be quickly disassembled through threads, and the installation and adjustment are convenient. In order to meet the connection work between the main body 15 and different types of pipes, the upper end of the stud 11 is connected to the collar 22 through a universal ball. The universal ball can make the stud 11 freely adjust the connection angle with the collar 22 during work, so as to facilitate the installation of the main body 15 to a suitable angle.

[0023] The cooperation between the stud 11 and the collar 22 can make the angle between the main body 15 and the pipe, but cannot be fixed very well. During operation, the main body 15 may experience various situations such as angle deviation due to vibration on the pipe, which affects the test accuracy during operation. Therefore, the rear side of the main body 15 is provided with a connecting device connected to the stud 11, and the connecting device includes a chuck 24, and the chuck 24 is rotatably connected to the rear end face of the 15. A support rod 21 is rotatably connected to the chuck 24, and the other free end of the support rod 21 is connected and fixed to the stud 11, so that the main body 15, the support rod 21, and the stud 11 are combined to form a triangle, thereby ensuring a stable state.

[0024] However, the main body 15, the chuck 24, and the collar 22 are all rotatably connected, and may rotate around their own axis during operation. Therefore, a plurality of slots 25 are provided on the circumference of the main body 15. The slots 25 are arranged in a circular array on the circumference of the main body 15, and the slots 25 are connected with the counterweight column 23. Figure 2 As shown, by setting different numbers of the counterweight columns 23, the center of gravity of the main body 15 can be changed, thereby reducing the deviation of the main body 15 during operation. The counterweight columns 23 can be embedded in only a few of the slots 25 as needed. The side with the counterweight columns 23 will sag under the action of gravity, making it difficult for the main body 15 to rotate.

[0025] And as Figure 3As shown, the connection between the chuck 24 and the support rod 21 is movable, while the connection between the support rod 21 and the stud 11 is an adjustable connection.

[0026] Among them, a receiving groove 34 is provided on the rear end surface of the chuck 24. The receiving groove 34 passes through the center of the end surface of the chuck 24, and the receiving groove 34 penetrates up and down, wherein, the two side walls of one end of the receiving groove 34 are connected with an extended connecting groove 31, and a rotating shaft 32 extending into the receiving groove 34 is rotatably installed in the connecting groove 31, and the rotating shaft 32 is fixedly connected to the upper end of the support rod 21, so that the support rod 21 can adjust the angle and connect with the chuck 24 conveniently.

[0027] Furthermore, the upper side of the support rod 21 passes through the rotating shaft 32, and the upper end of the support rod 21 passes through the rotating shaft 32. At the same time, the upper end of the support rod 21 is rounded, and the bottom wall of the accommodating groove 34 is slidably installed with a limiting plate 33 on the upper side of the rotating shaft 32. The limiting plate 33 and the upper end of the support rod 21 are in abutment state, and the limiting plate 33 can slide out of the accommodating groove 34 upward. At the same time, when the support rod 21 is connected in cooperation, it will rotate around the rotating shaft 32 to achieve angle change, and the limiting plate 33 can slide into the accommodating groove 34 after the support rod 21 is rotated. At this time, the limiting plate 33 abuts against the rotated support rod 21, and the friction force is increased by squeezing, thereby limiting the rotation of the support rod 21, ensuring the stability of the angle adjustment, and making the connection more stable. Figure 4 shown.

[0028] As for the connection between the support rod 21 and the stud 11, in the present embodiment, two connecting plates 12 are connected to the stud 11, and the connecting plates 12 and the stud 11 are movably connected. The two connecting plates 12 are horizontally arranged up and down. At the same time, a gap is left between the two connecting plates 12, and the connecting plate 12 is rotatably connected to a rocker 14 at the gap. One end of the upper and lower rockers 14 are respectively connected to the two connecting plates 12, and the other free ends are rotatably connected together through a rotating shaft. At the same time, one end of the two rockers 14 connected together is connected to the lower end of the support rod 21. Through the movement of the upper and lower rockers 14, the distance between the support rod 21 and the stud 11 is adjusted, thereby coordinating the adjustment of the rotation angle of the main body 15.

[0029] Furthermore, the two connecting plates 12, the connecting plate 12 on the side away from the main body 15 and the screw rod 11 are rotationally connected, while the connecting plate 12 on the side close to the main body 15 is not directly connected to the stud 11. The connecting plate 12 can slide on the stud 11 and can rotate at the same time, so as to facilitate the adjustment of the state of the rocker 14 between the two connecting plates 12, thereby cooperating with the support rod 21 for adjustment.

[0030] The connection between the two connecting disks 12 is fixed by a locking rod 13 to prevent the rocker arm 14 from becoming loose and affecting fixation after being adjusted to a suitable position due to changes in external factors, wherein the locking rod 13 and any one of the connecting disks 12 are rotationally connected, and the locking rod 13 and another connecting disk 12 are threadedly connected. The locking rod 13 is a threaded rod, and a self-locking effect is achieved through the threaded connection to prevent the gap between the two connecting disks 12 from changing. At the same time, rotating the locking rod 13 can control the gap between the two connecting disks 12, and can more efficiently adjust the angle of the rocker arm 14 to cooperate with the adjustment work of the support rod 21.

[0031] The working process of this embodiment is mainly to connect the stud 11 and the pipeline through the stud 11 first. At this time, the support rod 21 is not locked. After the stud 11 is connected, the basic position of the main body 15 is fixed. At the same time, the orientation of the main body 15 is adjusted, and the stud 11 is tightened until the connecting plate 12 and the connecting part of the pipeline are abutted to realize the limiting function. At the same time, the rotation of the connecting plate 12 is limited by friction, thereby limiting the rotation angle of the main body 15 around the stud 11, and then the main body 15 itself is adjusted. The appropriate counterweight column 23 is embedded in the slot 25 to limit the angle of the main body 15, and then the chuck 24 and the inclination angle of the main body 15 are rotated to a suitable position, and the limiting piece 33 is inserted into the gap between the support rod 21 and the accommodating groove 34 to limit the rotation of the support rod 21. When the angle of the support rod 21 is adjusted, the locking rod 13 can be rotated to adjust the angle of the rocker for convenient fixation.
