Description

Technical Field

[0001] The utility model relates to the technical field of filter differential pressure gauge brackets, in particular to a non-weldable adjustable bracket for a filter differential pressure gauge. Background Art

[0002] A filter differential pressure gauge is an instrument for measuring the differential pressure before and after a filter, used to monitor the operating state of the filter. Especially in an air or liquid filtration system, the filter differential pressure gauge provides real-time filter state information by measuring the pressure difference between the inlet and outlet of the filter.

[0003] Currently, an adjustable bracket for a filter differential pressure gauge in the prior art usually uses a welding method to be fixed to the filter. However, most filters belong to pressure vessels. According to the pressure vessel code TSG-21, some enterprises are not allowed to weld without qualifications. Therefore, for the situation where the position of the differential pressure gauge bracket needs to be changed, or for the situation where the container cost is saved and no longer repaired, a differential pressure gauge bracket installed by a non-welding process is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that traditional fixing usually uses a welding method and the welding type is inconvenient to adjust, and to propose a non-weldable adjustable bracket for a filter differential pressure gauge.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A non-weldable adjustable bracket for a filter differential pressure gauge includes a filter main body. A first flange is fixedly arranged outside the bottom end of the filter main body. A second flange is arranged at the bottom end of the first flange. The first flange and the second flange are fixed by a first bolt. A differential pressure gauge mounting bracket is arranged at the top end of the first flange. An insertion piece is arranged between the first bolt and the first flange. The insertion piece is fixed to the differential pressure gauge mounting bracket by a second bolt.

[0007] Preferably, a connecting plate is fixedly arranged on the outer wall of the bottom end of the differential pressure gauge mounting bracket. A third opening matching the second bolt is formed in the connecting plate.

[0008] Preferably, a first opening matching the first bolt is formed at one end of the insertion piece, and a second opening matching the second bolt is formed at the other end of the insertion piece.

[0009] Preferably, a mounting groove is formed in the differential pressure gauge mounting bracket, and a mounting hole is formed on one side of the mounting groove in the differential pressure gauge mounting bracket.

[0010] Preferably, the threaded end of the first bolt penetrates through the insertion piece, the first flange and the second flange, and a nut is threadedly connected to the outer wall of the first bolt below the second flange.

[0011] Preferably, the number of the inserts is two, and one ends of the two inserts are respectively installed with two ends of the connecting plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are that

[0013] The present utility model mainly consists of a differential pressure gauge mounting bracket and inserts. During installation, first, the inserts are installed by using the first bolts of the filter body itself, and then the connecting plate fixed to one end of the differential pressure gauge mounting bracket and the two inserts are pre-fastened by using the second bolts. After adjusting the differential pressure gauge mounting bracket to face the front, fasten it again. For filter bodies of different specifications, the distances between the first bolts of the filter body itself are different. The inserts of this design can adjust the rotation angle, and can be adjusted by using the third opening in the connecting plate and the first opening and the second opening in the inserts, and can adapt to filter bodies of various sizes, with stronger practicability.

The first flange 2 and the second flange 3 are fixed by a first bolt 4. A differential pressure gauge mounting bracket 6 is arranged at the top end of the first flange 2. An insert piece 7 is arranged between the first bolt 4 and the first flange 2. The insert piece 7 is fixed to the differential pressure gauge mounting bracket 6 by a second bolt 8.

[0022] The overall effect achieved by the entire Embodiment 1 is that this device is mainly composed of a differential pressure gauge mounting bracket 6 and an insert piece 7. During installation, first, the insert piece 7 is installed by using the first bolt of the filter body 1 itself. Then, the connecting plate 13 fixed to one end of the differential pressure gauge mounting bracket 6 and the two insert pieces 7 are pre-fastened by a second bolt 8. After adjusting the differential pressure gauge mounting bracket 6 to face the front, it can be fastened again. For filter bodies 1 of different specifications, the distances between the first bolts 4 of their own are different. The insert piece 7 of this design can rotate the angle, and can be adjusted by using the third opening 14 in the connecting plate 13 and the first opening 11 and the second opening 12 in the insert piece 7, and can adapt to filter bodies 1 of various sizes, with stronger practicability.

[0023] Embodiment 2, as Figures 1-4 shown, a connecting plate 13 is fixedly arranged on the outer wall of the bottom end of the differential pressure gauge mounting bracket 6. A third opening 14 matching the second bolt 8 is arranged in the connecting plate 13. A first opening 11 matching the first bolt 4 is arranged at one end of the insert piece 7. A second opening 12 matching the second bolt 8 is arranged at the other end of the insert piece 7. An installation groove 9 is arranged in the differential pressure gauge mounting bracket 6. An installation hole 10 is arranged on one side of the installation groove 9 in the differential pressure gauge mounting bracket 6. The threaded end of the first bolt 4 penetrates through the insert piece 7, the first flange 2 and the second flange 3. A nut 5 is threadedly connected to the outer wall of the first bolt 4 below the second flange 3. The number of insert pieces 7 is two, and one ends of the two insert pieces 7 are respectively installed with the two ends of the connecting plate 13.
