[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure measuring device for a boiler, comprising a boiler assembly, wherein a measuring mechanism is provided on the top of the boiler assembly to improve the accuracy of pressure measurement, and the measuring mechanism includes:

[0007] The disassembly and assembly unit is located above the boiler unit;

[0008] A throttling unit, located above the disassembly unit, includes a connecting pipe. The connecting pipe has a groove inside, and a sliding frame is slidably installed inside the groove. Four throttling orifice plates are fixedly installed inside the sliding frame. Insertion holes are provided on both the left and right sides of the connecting pipe, and a pressure measuring gauge is fixedly installed at the top of the connecting pipe.

[0009] Preferably, the disassembly and assembly unit includes a fixing tube, and fixing brackets are fixedly installed on both the left and right sides of the fixing tube. A plug is slidably installed through the inside of the fixing bracket, and one end of the plug passes through the fixing tube and is adapted to be inserted into the inside of the plug hole.

[0010] Preferably, a sliding ring is slidably mounted on the outside of the insertion post, and a linkage post is fixedly mounted on both the front and rear sides of the sliding ring. A reset spring is sleeved on the outside of the insertion post.

[0011] Preferably, connecting columns are fixedly installed on both the left and right sides of the fixed tube, and a rotating frame is rotatably installed at one end of the connecting column. The two rods of the rotating frame are provided with linkage grooves, and the linkage column slides in the linkage grooves.

[0014] This invention provides a pressure measuring device for boilers. Compared with the prior art, it has the following advantages:

[0015] (1) The pressure measuring device for boiler is equipped with a throttling unit. The sliding frame is installed inside the connecting pipe through a sliding groove. At the same time, four throttling orifice plates are installed in an array inside the sliding frame. When the steam inside the boiler flows to the pressure measuring gauge at the top of the connecting pipe through the orifice of the four throttling orifice plates, the flow rate of the fluid can be accurately calculated by the pressure difference before and after the steam flows through the orifice of the throttling orifice plate, thereby improving the accuracy and stability of the detection.

[0016] (2) The pressure measuring device for boilers is equipped with a disassembly and assembly unit. When the user holds the two rotating frames, the two rotating frames rotate synchronously in opposite directions around the ends of the two connecting columns. At the same time, when the rotating frames rotate, they drive the linkage column to slide inside the linkage groove, thereby causing the linkage column to move the sliding ring to squeeze the reset spring, so that one end of the insertion column is pulled out from the inside of the insertion hole, thereby realizing the disassembly and assembly of the disassembly and assembly unit. This facilitates the cleaning of the inside of the connecting pipe and avoids the accumulation of particles in the orifice of the throttling orifice plate, which would reduce the measurement accuracy of the pressure measuring gauge.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A pressure measuring device for a boiler includes a boiler assembly 1. A measuring mechanism 2 is disposed on the top of the boiler assembly 1 to improve the accuracy of pressure measurement. The measuring mechanism 2 includes:

[0025] The disassembly and assembly unit 21 is located above the boiler unit 1;

[0026] The throttling unit 22 is located above the disassembly unit 21 and includes a connecting pipe 221. The connecting pipe 221 has a groove 223 inside, and a sliding frame 224 is slidably installed inside the groove 223. Four throttling orifice plates 225 are fixedly installed inside the sliding frame 224. Insertion holes 222 are provided on both the left and right sides of the connecting pipe 221, and a pressure measuring gauge 3 is fixedly installed at the top of the connecting pipe 221.

[0027] The sliding frame 224 is slidably installed inside the connecting pipe 221 via the sliding groove 223. At the same time, four throttling orifice plates 225 are installed in an array inside the sliding frame 224. When the steam inside the boiler flows to the pressure measuring gauge 3 at the top of the connecting pipe 221 through the orifices inside the four throttling orifice plates 225, the flow rate of the fluid can be accurately calculated by the pressure difference before and after the steam flows through the orifice inside the throttling orifice plates 225, thereby improving the accuracy and stability of the detection.

[0028] The sliding bracket 224 is slidably inserted into the interior of the connecting pipe 221 through the sliding groove 223, which facilitates the disassembly of the sliding bracket 224 and the cleaning of the throttling orifice plate 225.

[0029] In this embodiment, the disassembly and assembly unit 21 includes a fixed tube 211. Fixed brackets 214 are fixedly installed on both the left and right sides of the fixed tube 211. Insertion pins 2111 are slidably installed inside the fixed brackets 214. One end of the insertion pin 2111 passes through the fixed tube 211 and is adapted to be inserted into the interior of the insertion hole 222. A sliding ring 216 is slidably installed on the outside of the insertion pin 2111. Linkage pins 217 are fixedly installed on both the front and rear sides of the sliding ring 216. A reset spring 215 is sleeved on the outside of the insertion pin 2111. Connecting pins 218 are fixedly installed on both the left and right sides of the fixed tube 211. A rotating bracket 219 is rotatably installed on one end of the connecting pin 218. Linkage grooves 2110 are opened inside the two rods of the rotating bracket 219. The linkage pins 217 are adapted to slide inside the linkage grooves 2110.

[0030] The user holds the two rotating frames 219, causing them to rotate synchronously in opposite directions around the endpoints of the two connecting columns 218. As the rotating frames 219 rotate, they drive the linkage column 217 to slide inside the linkage groove 2110. This causes the linkage column 217 to move the sliding ring 216 and press the reset spring 215, allowing one end of the insertion column 2111 to be pulled out from inside the insertion hole 222. This enables the disassembly and assembly of the disassembly unit 21, facilitating the cleaning of the inside of the connecting pipe 221 and preventing the accumulation of particles in the orifice of the throttling orifice plate 225, which could lead to a decrease in the measurement accuracy of the pressure gauge 3.

[0031] In this embodiment, a retaining ring 212 is fixedly installed inside the fixed tube 211, and a sealing gasket 213 is installed between the retaining ring 212 and the connecting tube 221.

[0032] A sealing gasket 213 is installed between the retaining ring 212 and the connecting pipe 221 to improve the sealing performance of the connection between the retaining ring 212 and the connecting pipe 221.

[0033] In this embodiment, the boiler device 1 includes a base frame 11, a tank 12 is fixedly installed on the top of the base frame 11, a controller 13 is fixedly installed on the front side of the tank 12, a sealing cover 14 is fixedly installed on the top of the base frame 11, a drain outlet 15 is fixedly installed on the bottom of the base frame 11, and a fixing pipe 211 is fixedly installed on the top of the base frame 11.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, steam inside the base frame 11 enters the interior of the connecting pipe 221 through the fixed pipe 211. At this time, the steam flows through the holes inside the four throttling orifice plates 225 to the pressure measuring gauge 3 at the top of the connecting pipe 221 for pressure measurement. When cleaning the interior of the connecting pipe 221, the user pinches the two rotating frames 219, causing the two rotating frames 219 to rotate synchronously in opposite directions around the endpoints of the two connecting columns 218. At the same time, when the rotating frames 219 rotate, they drive the linkage column 217 to slide inside the linkage groove 2110, thereby causing the linkage column 217 to drive the sliding ring 216 to move and squeeze the return spring 215, causing one end of the insertion column 2111 to be pulled out from the inside of the insertion hole 222, thus cleaning the interior of the connecting pipe 221.
