[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-3 The utility model provides a technical scheme:

[0032] A coaxial type breathing valve disc opening height detection device, including the valve body 101 installed in the storage tank or pipeline, for controlling the air inlet and outlet of the storage tank or pipeline;

[0033] The valve cover 1 is installed on the top of the valve body 101, and the air inlet and outlet 104 is installed on one side of the valve body 101, so that the air inlet and outlet of the valve body 101 is realized, the corresponding air exhaust valve disc 6 is installed on the air exhaust valve seat 102, and the corresponding air suction valve disc 3 is installed on the air suction valve seat 103;

[0034] The light transmission hole is arranged on the valve cover 1, and the light transmission hole is sealed by the transparent sealing plate 2, the disc hole corresponding to the light transmission hole is arranged on the air suction valve disc 3, and the sealing plug 5 (black sealing rubber) is arranged in the disc hole, so as to seal the disc hole and prevent the light from penetrating, so that the sealing requirement of the valve cover 1 and the air suction valve disc 3 is realized, and the opening height of the air suction valve disc 3 is also convenient to measure;

[0035] The laser ranging device for detecting the opening height of the valve disc is installed on the top of the transparent sealing plate 2, so that the measurement data can be obtained in real time, in order to realize the independent sealing and separation of the sealing plug 5, the driving structure 7 for driving the sealing plug 5 to move is installed between the valve cover 1 and the air suction valve disc 3, so that the end of the driving structure 7 is hinged with the sealing plug 5, when the opening height of the air exhaust valve disc 6 needs to be measured, the driving mechanism 7 is retracted, the sealing plug 5 is lifted by the driving mechanism 7 at the same time and is folded by 90 degrees, the laser penetrates the disc hole on the air suction valve disc 3 and irradiates to the air exhaust valve disc 6, and the opening height of the air exhaust valve disc 6 is measured.

[0036] As shown in Figure 1

[0037] The transparent sealing plate 2 is a transparent acrylic plate, so that the laser can penetrate the sealing plate 2 to measure the opening height of the air suction valve disc 3.

[0038] As shown in Figure 1

[0039] ​​In order to facilitate the height measurement of the suction valve disc 3, the light transmission hole and the disc hole are coaxially arranged, which ensures the accuracy during the measurement and does not need to be separately disassembled.

[0040] As shown in Figure 1 :

[0041] The driving structure 7 is composed of a guide column and a telescopic oil cylinder, and the guide column is arranged between the piston and the cylinder barrel of the telescopic oil cylinder. The piston end of the telescopic oil cylinder is hingedly connected to the sealing plug. The telescopic oil cylinder drives the movement of the sealing plug 5. When the telescopic oil cylinder is retracted, the sealing plug 5 is lifted and folded by 90 degrees. At this time, the laser can pass through the disc hole on the suction valve disc 3 and irradiate on the exhalation valve disc 6, which is convenient for measurement.

[0042] As shown in Figure 1 :

[0043] The transparent sealing plate 2 and the sealing plug 5 are both circular. The diameter of the transparent sealing plate 2 is smaller than that of the sealing plug 5. When the laser irradiates on any point on the transparent sealing plate 2, the laser can irradiate on the suction valve disc 3, which avoids the error caused by the deviation of the position.

[0044] As shown in Figure 1 :

[0045] The laser ranging device is composed of a laser ranging sensor 4, a data communication module 41 and a terminal 42. When the laser ranging sensor 4 performs laser ranging, the light enters the inside of the valve body 1. The measured data is uploaded to the data communication module 41 in real time. The data communication module 41 transmits the data to the terminal 42 for viewing or storage, which is convenient to use. In order to display the measurement data in real time and facilitate on-site observation, a display is installed on the laser ranging sensor 4, and the display is used for viewing.

[0046] In order to facilitate control, the device is also provided with a control device in communication connection with the driving structure. The control device is a PLC controller (Siemens S7-200).

[0047] As shown in Figures 2-3 :

[0048] When the suction valve disc 3 is opened upward and the exhalation valve disc 6 is closed, the gas enters through the inlet and outlet port 104, and then forms an inlet channel 105 between the suction valve disc 3 and the exhalation valve disc 6. The gas enters the storage tank or pipeline along the inlet channel 105;

[0049] When the suction valve disc 3 is closed and the exhalation valve disc 6 is opened upward, an exhalation channel 106 is formed between the exhalation valve disc 6 and the inlet and outlet port 104. The gas in the storage tank or pipeline is discharged outward through the exhalation channel 106.

[0050] Example 2:

[0051] Different from embodiment 1, the transparent sealing plate 2 and the sealing plug 5 are arranged in a circular ring shape, the circular ring shape is concentric with the valve disc, the area of the circular ring shape is smaller than the area of the valve disc, since the valve disc is circular, the center of the circular ring shape is the center of the valve disc, and the area of the circular ring shape is smaller than the area of the valve disc, which ensures that the outer diameter of the circular ring shape is smaller than the outer diameter of the valve disc, thereby increasing the detection area, and a plurality of laser ranging devices (evenly distributed along the side of the sealing plug 5) can be arranged above the circular ring shape to simultaneously detect the opening height of the valve disc, thereby improving the accuracy of detection.

[0052] Working principle:

[0053] When it is necessary to measure the opening height of the exhalation valve disc 6, the sealing plug 5 of the inhalation valve disc 3 is lifted by the contraction of the telescopic oil cylinder (the sealing plug 5 is folded by 90 degrees when being lifted), so that the laser can pass through the disc hole and irradiate on the exhalation valve disc 6, when the storage tank or the pipeline is overpressure, the exhalation valve disc 6 opens to release the gas in the tank or the pipeline, and when the pressure is constant, the inhalation valve disc 3 falls back, in this process, the laser ranging sensor 4 irradiates on the exhalation valve disc 6 (the laser passes through the disc hole on the inhalation valve disc 3, and the light transmission hole and the disc hole are coaxially arranged, so as not to affect the light), the height change of the valve disc is detected and recorded in real time (uploaded to the data communication module 41, and finally transmitted to the terminal 42 for storage), and the maximum value is the opening height of the exhalation valve disc 6.

[0054] When it is necessary to measure the opening height of the inhalation valve disc 3, the telescopic oil cylinder is elongated to drive the sealing plug 5 to cover the disc hole, when the storage tank or the pipeline is under vacuum negative pressure, the inhalation valve disc 3 opens to inhale the gas, and when the pressure is constant, the inhalation valve disc 3 falls back, in this process, the laser ranging sensor 4 irradiates on the inhalation valve disc 3, the height change of the valve disc is detected and recorded in real time (uploaded to the data communication module 41, and finally transmitted to the terminal 42 for storage, and the terminal is a PC computer), and the maximum value is the opening height of the inhalation valve disc 3.

[0055] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
