DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-4 A multi-parameter transmitter shown includes a measuring cylinder 1 and a multi-parameter measuring meter 6. The multi-parameter measuring meter 6 is arranged in the middle of the measuring cylinder 1. A conduit 101 is inserted and connected to the middle of the measuring cylinder 1. The measuring end of the multi-parameter measuring meter 6 is inserted and connected to the conduit 101.

[0026] It should be noted that a multi-parameter transmitter is a device used to measure and transmit multiple physical quantities. They are usually used in industrial control and monitoring systems and can simultaneously measure and transmit multiple parameters, such as temperature, pressure, flow, humidity, etc. In this solution, sensors and circuits are set in the multi-parameter measurement table 6, which can convert the signals of various physical quantities into standard electrical signal outputs, such as 4-20mA current signals or 0-10V voltage signals, so as to be used for remote monitoring or control systems.

[0027] Specifically, a flange 7 for connecting the multi-parameter measuring meter 6 and the conduit 101 is provided between the interpenetration of the two. In the present embodiment, the multi-parameter measuring meter 6 is connected to the conduit 101 through a flange-like structure, so that the measuring element in the multi-parameter measuring meter 6 extends from the conduit 101 into the measuring cylinder 1, so that the parameter measurement is performed after the measured object flows through the measuring cylinder 1.

[0028] Furthermore, a plurality of connection terminals 601 are provided on the side of the multi-parameter measurement meter 6 .

[0029] Protective cylinders 2 are provided at both ends of the measuring cylinder 1, and flanges 3 are provided on the side of the multiple protective cylinders 2 away from the measuring cylinder 1. A sealing mechanism for protection is inserted and connected in the middle of the protective cylinder 2. The sealing mechanism includes a sealing plate 4, and a sealing block 8 inserted and connected to the inner wall of the protective cylinder 2 is provided on one side of the sealing plate 4.

[0030] Specifically, a connector for connecting the outer wall of the blocking plate 4 and the top of the flange 3 is provided between the two, and the connector includes:

[0031] A first connecting ring 301, which is arranged on the top of the flange 3;

[0032] A second connecting ring 401, which is arranged on the outer wall of the blocking plate 4;

[0033] The connecting rope 5 has two ends which are respectively sleeved on the middle of the first connecting ring 301 and the second connecting ring 401 .

[0034] It should be noted that, through the structural combination design of the first connecting ring 301, the second connecting ring 401 and the connecting rope 5, the entire sealing mechanism can be suspended at both ends of the protective cylinder 2. In this way, when the entire sealing mechanism is removed, the connection between the three can also be utilized to prevent the sealing mechanism from falling off, thereby making the sealing mechanism easy to take and use.

[0035] Specifically, the outer wall of the blocking block 8 is provided with a plurality of receiving chutes, and an extrusion piece is provided between the outer wall of the blocking block 8 and the inner wall of the protective cylinder 2, and the extrusion piece includes:

[0036] Extrusion blocks 9, multiple extrusion blocks 9 are respectively slidably inserted and connected in multiple storage chutes, and the inner walls on both sides of the multiple storage chutes are provided with support chutes;

[0037] A supporting spring 10, wherein a plurality of supporting springs 10 are respectively disposed in a plurality of supporting slide grooves.

[0038] Furthermore, both sides of the multiple extrusion blocks 9 are fixedly connected with support sliders 901, and the multiple support sliders 901 are respectively slidably inserted and connected in the multiple support sliding grooves.

[0039] It should be noted that, in the present embodiment, the outer ring wall of the blocking block 8 has the same radius as the inner ring wall of the protective cylinder 2. Through the setting of the extrusion piece, the blocking block 8 can be better embedded in the protective cylinder 2. After the extrusion block 9 is extruded, it will move toward the direction close to the blocking block 8 and drive the connected supporting slider 901 to move synchronously. During the movement, the supporting spring 10 will be squeezed, and at the same time, the restoring force of the supporting spring 10 will react to the supporting slider 901, causing the extrusion block 9 to move away from the blocking block 8, thereby allowing the blocking block 8 to remain in an inserted state in the protective cylinder 2.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
