Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauges, in particular to a flange-type connection pressure gauge. Background Art

[0002] Flange pressure gauge is a pressure gauge suitable for chemical industry, chemical fiber, synthetic fiber, petroleum, dyeing, alkali and other industries. The diaphragm pressure gauge adopts an indirect measurement structure and is suitable for measuring the pressure of granular solid media in liquids and gases with high viscosity, easy crystallization, high corrosiveness and high temperature. The existing flange pressure gauge has certain disadvantages when used. When installing the flange, it needs to be operated through axial installation or longitudinal installation according to the installation environment. The installation structure of the pressure gauge is mostly located on the surface or rear of the pressure gauge and cannot be adjusted according to actual conditions. The flexibility is poor. The pressure gauge will produce certain vibrations during operation, which will have a certain impact on the pressure value, resulting in a large error in the measured pressure value. For this reason, we propose a flange connection pressure gauge. Utility Model Content

[0022] The pressure gauge body 1 includes a mounting rod 101, a first screw hole 102, a pointer 103, and a table body 104. The pointer 103 is embedded in the interior of the table body 104, and the surface of the table body 104 is fixedly mounted with the mounting rod 101. The bottom surface of the mounting rod 101 is arc-shaped, so that the fixing plate 204 can better rotate with the mounting rod 101 as the axis. A first screw hole 102 is opened on one side surface of the mounting rod 101; the fixing structure 2 includes a connecting plate 201, a fixing bolt 202, a second screw hole 203, and a fixing plate 204. The upper surface of the fixing plate 204 is located near the two sides and is fixedly mounted with the connecting plate 201. The connecting plate A second screw hole 203 is provided on one side surface of the block 201; the pressure gauge body 1 and the fixing structure 2 are embedded and installed between the connecting plates 201 through the mounting rod 101, and the fixing bolts 202 are embedded and installed inside the second screw holes 203 and the first screw holes 102; the shock absorbing structure 3 includes a first mounting plate 301, a sealing ring 302, a second mounting plate 303, a support column 304, a first connecting rod 305, a sleeve 306, a shock absorbing spring 307, a fixing block 308, a second connecting rod 309, an inclined rod 310, and a gas spring 311. The upper surface of the second mounting plate 303 is embedded with a sealing ring 302, a sealing ring 3 02 can seal the gap between the first mounting plate 301 and the second mounting plate 303. The inner surface of the sealing ring 302 is embedded with the first mounting plate 301. The lower surface of the first mounting plate 301 is fixedly installed with a sleeve 306. There are two groups of sleeves 306. The lower surfaces of the sleeves 306 are embedded with support columns 304. Shock-absorbing springs 307 are fixedly connected between the sleeves 306 and the support columns 304. There are two groups of shock-absorbing springs 307. A second connecting rod 309 is fixedly connected between the sleeves 306 near the upper position. A fixing block 308 is sleeved on the surface of the second connecting rod 309. A first connecting rod 305 is fixedly connected between the support columns 304, and a gas spring 311 is installed on the surface of the first connecting rod 305. The fixed block 308 and the gas spring 311 are movably connected through an inclined rod 310. The inclined rod 310 is in two groups. The fixed block 308 is fixed on the surface of the second connecting rod 309, and the gas spring 311 is movably installed on the surface of the first connecting rod 305.

When the gauge body 104 needs to be installed longitudinally, the mounting rod 101 and the fixing plate 204 are in the same plane. When the mounting rod 101 needs to be installed axially, the fixing bolts 202 inside the first screw hole 102 and the second screw hole 203 are loosened, and the fixing plate 204 is rotated so that the mounting rod 101 is at a right angle to the connecting plate 201, and then the fixing bolts 202 are tightened to fix it. When the mounting rod 101 vibrates, the first mounting plate 301 moves up and down inside the second mounting plate 303. The first mounting plate 301 and the second mounting plate 303 are sealed by the sealing ring 302. At the same time, the sleeve 306 and the support column 304 are extended and retracted under the action of the shock-absorbing spring 307, thereby playing a certain buffering role. When the sleeve 306 moves, it drives the second connecting rod 309 to move, thereby causing the fixed block 308 to move up and down. Under the connection action of the inclined rod 310, the gas spring 311 on the surface of the first connecting rod 305 is driven to extend and retract, thereby enhancing its buffering and shock-absorbing effect.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
