Description

Technical Field

[0001] The utility model relates to the technical field of industrial pressure display meters, in particular to an industrial pressure display meter which is easy to assemble. Background Art

[0002] Industrial pressure indicator, that is, the pressure gauge commonly used in industry, is an important instrument used to measure and display the pressure in the industrial process. The pressure gauge converts the pressure into the displacement of the pointer through the elastic deformation of the internal sensitive elements (such as Bourdon tube, diaphragm box, bellows), thereby displaying the pressure value.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN219776821U discloses an industrial pressure gauge, which is used in conjunction with bolts, a back cover, heat dissipation holes and a heat dissipation fan. When the device is used for a long time, the temperature of the pressure gauge body will rise. Turning on the switch of the heat dissipation fan in conjunction with the setting of the heat dissipation holes will drive the air circulation inside and outside the back cover, which can dissipate the heat of the pressure gauge body and effectively improve the service life of the device. At the same time, the setting of the bolts makes it convenient for the staff to remove the back cover to inspect the heat dissipation fan. However, when installing the pressure gauge, in order to ensure the sealing of the connection, it is usually necessary to wrap raw tape around the connector and then tighten it for installation. After the raw tape is wrapped around the connector, it will make it inconvenient to screw the connector into the pipe, and the raw tape will age easily after long-term use, which will affect the sealing of the pressure gauge.

[0004] Therefore, the utility model provides an industrial pressure display meter which is easy to assemble to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The utility model provides an industrial pressure display gauge which is easy to assemble, and aims to solve the problems in the background technology that the existing pressure gauge needs to be sealed by raw tape during installation, which is inconvenient to install.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an industrial pressure display gauge that is easy to assemble, comprising a gauge body, a connecting pipe arranged on the gauge body, and a fixing ring sleeved on the connecting pipe.

[0009] In order to solve the problem of convenient installation of the pressure display gauge, the end of the fixing ring away from the gauge body is symmetrically provided with an extrusion airbag, the outer edge of the end of the connecting tube away from the gauge body is provided with a sealing airbag ring, a catheter is provided through the extrusion airbag, the end of the catheter away from the extrusion airbag passes through the connecting tube and is connected to the sealing airbag ring, and the fixing ring is provided with an extrusion mechanism for extruding the extrusion airbag. By using the extrusion airbag and the sealing airbag ring in combination, the pressure display gauge does not need to be sealed with raw tape when installed, and the staff can directly install it, and the installation position can be sealed by the sealing airbag ring to ensure the sealing performance during use.

[0010] Preferably, in order to solve the squeezing problem of the squeezing airbag, the squeezing mechanism includes a groove symmetrically provided at the end of the fixing ring away from the watch body, a strut slidably installed in the groove, and a pressure ring fixedly installed at the end of the strut away from the groove and adapted to the squeezing airbag, and a supporting spring is fixedly installed between the strut and the groove. Through the coordinated use of the pressure ring and the strut, the pressure ring can evenly squeeze the squeezing airbag when the connecting pipe is screwed into the installation position, ensuring that the inflation process of the sealing airbag ring is more uniform.

[0011] Preferably, in order to solve the adaptability problem of the pressure ring, the outer diameter of the pressure ring is the same as the outer diameter of the fixing ring. By setting the size of the pressure ring, the pressure ring can be connected to the position of the fixing ring after the pressure display gauge is installed, avoiding affecting the installation of other parts.

[0012] Preferably, in order to solve the problem of detecting the sealing performance at the installation position of the pressure display gauge, the connecting pipe is provided with a liquid reservoir ring at the position between the fixing ring and the gauge body, and the top of the liquid reservoir ring is penetrated by a plurality of mounting pipes distributed in a circular array, and a filling port is provided on the liquid reservoir ring. The sealing performance at the connection position can be detected by the foam water in the liquid reservoir ring, and the foam water can be stored in the liquid reservoir ring for daily detection.

[0013] Preferably, in order to solve the problem of adding foam water, the end of the installation tube away from the liquid storage bag ring is flush with the end of the fixing ring away from the meter body. By setting the end position of the installation tube, the foam water can be added to the surface of the meter body and the installation position after being squeezed out for detection.

The protective cover and the explosion-proof glass can be used together to protect the dial of the watch body and avoid scratches and bumps during use.

[0015] Preferably, in order to solve the installation problem of the protective cover, the buckle mechanism includes a card plate fixedly installed in the opening and a card head fixedly installed on the card plate and the opposite side of the watch body, and the watch body is provided with a card slot adapted to the card head. The protective cover can be quickly disassembled and installed by using the card head and the card slot in combination, which increases the convenience of the device.

[0016] (III) Beneficial effects

[0017] The industrial pressure display gauge which is easy to assemble has a simple structure and is easy to use. By arranging a sealing airbag ring and a mounting tube, the sealing airbag ring is filled with gas by squeezing two squeezing airbags through an squeezing mechanism, and the gap between the end of the connecting tube and the pipeline is effectively filled, thereby significantly enhancing the sealing performance at the connection position between the meter body and the pipeline, and making installation more convenient. Foam water is added to the liquid storage bag ring through the filling port, and the foam water is transported to the contact position between the connecting tube and the pipeline by the mounting tube. If a leak occurs at the connection, the foam water will generate bubbles, which is convenient for staff to quickly detect and identify the leak point, thereby improving the efficiency and accuracy of leak detection. At the same time, the protective cover and explosion-proof glass on the meter body effectively protect the dial from scratches and collisions, thereby extending the service life of the meter.

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.

[0024] Example 1

[0025] The utility model provides an industrial pressure display meter which is easy to assemble. Figure 1-4 As shown, the industrial pressure display gauge comprises a gauge body 1, a connecting pipe 2 arranged on the gauge body 1, and a fixing ring 6 sleeved on the connecting pipe 2;

[0026] The end of the fixing ring 6 away from the watch body 1 is symmetrically provided with an extrusion airbag 3, and the outer edge of the end of the connecting tube 2 away from the watch body 1 is provided with a sealing airbag ring 31. A catheter 32 is penetrated through the extrusion airbag 3, and the end of the catheter 32 away from the extrusion airbag 3 passes through the connecting tube 2 and is connected with the sealing airbag ring 31. The fixing ring 6 is provided with an extrusion mechanism 33 for extruding the extrusion airbag 3.

[0027] When in use, the connecting tube 2 can be connected to the monitoring pipeline. When connecting, first insert the connecting tube 2 into the pipeline and screw it through threads. During the tightening process of the connecting tube 2, the two extrusion airbags 3 can be squeezed by the extrusion mechanism 33. When the extrusion airbags 3 are squeezed, the gas inside the extrusion airbags 3 can enter the sealing airbag ring 31 through the conduit 32 and fill and seal the gap between the end of the connecting tube 2 and the pipeline, thereby ensuring the sealing of the connection position between the meter body 1 and the pipeline.

[0028] Specifically, the extrusion mechanism 33 includes a groove 331 symmetrically opened at the end of the fixing ring 6 away from the watch body 1, a strut 332 slidably installed in the groove 331, and a pressure ring 333 fixedly installed on the end of the strut 332 away from the groove 331 and adapted to the extrusion airbag 3, a support spring 334 is fixedly installed between the strut 332 and the groove 331, and the outer diameter of the pressure ring 333 is the same as the outer diameter of the fixing ring 6; in the process of screwing the connecting pipe 2 into the pipeline, the pressure ring 333 can first contact the pipeline, and as the connecting pipe 2 is screwed in, the pressure ring 333 can be squeezed and drive the strut 332 to slide in the groove 331, so that the pressure ring 333 evenly squeezes the extrusion airbag 3 and inflates the sealing airbag ring 31.

[0029] Furthermore, a protective cover 5 is provided at the outer edge of the dial end of the watch body 1, and an explosion-proof glass 52 is provided inside the protective cover 5. A plurality of make-way openings 51 distributed in a circular array are opened on the protective cover 5, and a snap mechanism 53 is provided inside the make-way openings 51; the protective cover 5 and the explosion-proof glass 52 on the watch body 1 can protect the dial position of the watch body 1 to avoid scratches and collisions.

[0030] More specifically, the snap mechanism 53 includes a card plate 531 fixedly installed in the yield opening 51 and a card head 532 fixedly installed on the card plate 531 and on the side opposite to the watch body 1. The watch body 1 is provided with a card slot 11 adapted to the card head 532. When installing the protective cover 5, the protective cover 5 can be snapped onto the outer edge of one end of the watch body 1 located on the dial, and the card head 532 is aligned with the card slot 11. The protective cover 5 can be pushed so that the card head 532 is snapped into the card slot 11, and the installation of the protective cover 5 is completed. When removing, the protective cover 5 can be directly pulled away from the watch body 1.

[0031] Example 2

[0032] Different from Example 1, the connecting tube 2 is provided with a liquid storage bag ring 4 between the fixing ring 6 and the meter body 1, and a plurality of mounting tubes 41 distributed in a circular array are penetrated through the top of the liquid storage bag ring 4, and a filling port 42 is provided on the liquid storage bag ring 4.

[0033] When in use, after the connecting tube 2 and the meter body 1 are installed, foam water or the like can be added and withdrawn from the liquid storage bag ring 4 through the filling port 42. By lightly pressing the liquid storage bag ring 4, the foam water can enter the installation tube 41 and flow through the installation tube 41 to the contact position between the fixing ring 6 and the pipeline. If a leak occurs at the connection, the foam water will be blown into bubbles, and the staff can use this to observe the sealing during maintenance.

[0034] Specifically, one end of the mounting tube 41 away from the liquid storage bag ring 4 is flush with one end of the fixing ring 6 away from the meter body 1; after the foam water enters the mounting tube 41, it can flow to the part where the connecting tube 2 contacts the pipeline under the action of pressure, so as to perform a sealing test.
