Description

Technical Field

[0001] The utility model relates to the technical field of a split-type pressure reducing valve, in particular to a split-type pressure reducing valve body. Background Art

[0002] The pressure reducing valve is a vital fluid control device. Its core function is to accurately reduce the higher inlet pressure to the required lower outlet pressure level. This process requires not only precise mechanical adjustment, but also the use of the kinetic energy of the medium itself to achieve automatic and stable maintenance of the outlet pressure.

[0003] In an external fume hood system, the pressure reducing valve is generally responsible for regulating and controlling the pressure of gas flowing to the laboratory fume hood to ensure a safe and effective operating environment. However, since each fume hood usually needs to be equipped with multiple pressure reducing valves to ensure uniform and stable airflow, a large number of pressure reducing valves are gathered together in a limited space, which is not only difficult to distinguish visually, but also brings difficulties to identification when the staff performs inspections or daily maintenance, which may lead to misoperation and even affect the overall performance of the system; at the same time, the installation and removal of the existing pressure reducing valve requires the removal of the mounting seat and then the pressure reducing valve on it, which is very cumbersome and reduces work efficiency.

[0010] Preferably, the movable plate and the through opening are vertically slidably connected.

[0011] Preferably, a pair of threaded columns are fixedly connected to the side of the arc-shaped plate opposite to the movable plate, through holes corresponding to the threaded columns are opened on the movable plate, and matching nuts are threadedly connected to the threaded columns.

[0012] Preferably, the magnetic card corresponds to the valve body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A valve body of a separately assembled pressure reducing valve comprises a mounting seat 1 and a valve body 2. A screw hole is provided on the mounting seat 1, and a limit screw 3 is connected to the inner thread of the screw hole. A plurality of magnetic strips 4 are fixedly connected to the mounting seat 1, and magnetic cards 5 are magnetically attracted to the magnetic strips 4. Each separately arranged magnetic card 5 makes it easier for the staff to identify the valve body 2.

[0021] The mounting seat 1 is provided with a fixing structure for independently clamping and fixing the valve body 2 .

[0022] The mounting seat 1 is arranged in a concave shape, and a plurality of through openings 11 are provided on the concave side of the mounting seat 1, so as to facilitate the clamping installation of the valve body 2, and the arrangement of the through openings 11 facilitates the installation of the valve body 2 on the fume hood.

[0023] The fixing structure includes a screw rod 6 threadedly connected to the mounting seat 1, and the screw rod 6 corresponds to the through hole 11. The bottom end of the screw rod 6 extends to the concave side of the mounting seat 1 and is rotatably connected to a movable plate 7. An arc plate 8 is fixedly installed on the movable plate 7. A support 9 is fixedly connected to the mounting seat 1. One end of the support 9 opposite to the arc plate 8 is fixedly connected to a placement table 10. After the valve body 2 is placed on the placement table 10, the screw rod 6 is screwed, and the arc plate 8 moves vertically downward under the drive of the screw rod 6 to clamp the fixed valve body 2.

[0024] The movable plate 7 and the through opening 11 are vertically slidably connected to ensure that the movable plate 7 can move vertically stably.

[0025] A pair of threaded columns 12 are fixedly connected on the side of the arc plate 8 relative to the movable plate 7. The movable plate 7 is provided with through holes 13 corresponding to the threaded columns 12. The threaded columns 12 are threadedly connected with matching nuts, so that the arc plate 8 can be easily replaced.

[0026] The magnetic card 5 corresponds to the valve body 2, which is convenient for the staff to identify.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] When using the device, first, after installing the mounting base 1 to a suitable position on the fume hood, tighten the limit screw 3 to fix the mounting base 1 relative to the fume hood;

[0029] The valve body 2 to be installed is placed on the placement table 10, and the screw 6 is screwed. The screw 6 drives the movable plate 7 to move vertically downward in the through opening 11, and the movable plate 7 drives the arc plate 8 to move vertically downward to clamp the fixed valve body 2. The magnetic card 5 corresponding to the valve body 2 is magnetically attracted on the magnetic strip 4, so that the staff can identify the valve body 2;

[0030] When the arc plate 8 needs to be replaced according to the actual size and model of the valve body 2, the nut is screwed to remove the threaded column 12 from the through hole 13, and then the arc plate 8 is removed. The reverse operation can be performed to achieve the installation of different arc plates 8.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
