Even if all the bolts of the existing powder flow meter are removed, the pressure from the mounting flange still makes disassembly difficult; the existing powder flow meter is installed at a high position, which makes it inconvenient for workers to operate and increases the difficulty of disassembly; the powder flow meter is also prone to thermal expansion and contraction, causing damage to the equipment structure. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art and solve technical problems such as the difficulty in disassembling the existing powder flowmeter and structural damage after thermal expansion and contraction, the utility model provides a telescopic powder flowmeter.

[0005] The utility model is implemented through the following technical solutions.

[0007] The upper shell is arranged in a circular ring shape, the top of the upper shell is connected to a first mounting flange, a flow meter ring is sleeved inside the upper shell, and connecting rod mounting holes are arranged at the side wall of the upper shell and the corresponding side wall of the flow meter ring, and the connecting rod passes through the connecting rod mounting hole at the side wall of the flow meter ring and the connecting rod mounting hole at the side wall of the upper shell in sequence, and then the end thereof is fixedly connected to the digital display meter;

[0008] The lower shell is arranged below the upper shell, a gap is arranged between the lower shell and the upper shell, the lower shell is arranged in a circular ring shape, and a second mounting flange is connected to the bottom end of the lower shell;

[0009] The fixing ring is sleeved on the outer side of the bottom end of the upper shell, the gap, and the outer side of the top end of the lower shell. The top and bottom ends of the fixing ring are both provided with stainless steel cable ties.

[0010] Furthermore, the inner and outer diameters of the upper shell are equal to the inner and outer diameters of the lower shell, and the height of the upper shell is equal to the height of the lower shell.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown, the telescopic powder flow meter is arranged between the gate valve 1 and the dome valve 2, and includes an upper shell 3, a lower shell 4 and a fixing ring 5.

[0025] The upper shell 3 is arranged in a circular ring shape, and a first mounting flange 6 is connected to the top of the upper shell 3, and the first mounting flange 6 is fixedly connected to the gate valve 1. A flow meter ring 7 is sleeved inside the upper shell 3, and the flow meter ring 7 is an electrostatic flow meter ring, which senses the charge generated by the flow of the fluid through the electrostatic effect to measure the flow rate of the fluid. Connecting rod mounting holes 8 are provided at the corresponding side walls of the upper shell 3 and the flow meter ring 7. The connecting rod 9 passes through the connecting rod mounting holes 8 at the side walls of the flow meter ring 7 and the connecting rod mounting holes 8 at the side walls of the upper shell 3 in sequence, and then the end is fixedly connected to a digital display 10. The digital display 10 displays the measurement structure in a digital form, which is more accurate and clear, and is convenient for users to quickly obtain measurement data.

[0026] The lower shell 4 is arranged below the upper shell 3, and the inner and outer diameters of the upper shell 3 are equal to the inner and outer diameters of the lower shell 4, and the height of the upper shell 3 is equal to the height of the lower shell 4. In this way, the upper shell 3 and the lower shell 4 are more convenient to seal. A gap 11 is arranged between the lower shell 4 and the upper shell 3, and the height of the gap 11 is configured according to the actual situation. The setting of the gap 11 divides the powder flow meter into two parts, upper and lower. After removing the fixing ring 5, the powder flow meter is not subjected to force on the upper and lower parts, and the disassembly is more convenient and simple. At the same time, the selection of the gap 11 can also absorb the deformation caused by the thermal expansion and contraction of the equipment in the axial direction of the powder flow meter, reduce the force of the equipment, and avoid the damage to the structure or strength of the equipment. If there is no gap 11, it is very difficult to remove the flow meter. Even if all the bolts are loosened, the pressure of the upper and lower flanges on the flow meter makes it very difficult to disassemble and assemble. In addition, the flow meter is 3 meters away from the ground, which is inconvenient to operate. In addition, with the setting of the gap 11, the upper shell 3 and the lower shell 4 can achieve the function of telescoping up and down in the height direction. The lower shell 4 is arranged in a circular ring shape, and a second mounting flange 12 is connected to the bottom end of the lower shell 4 . The second mounting flange 12 is fixedly connected to the dome valve 2 .

[0027] The fixing ring 5 is sleeved on the outside of the bottom end of the upper shell 3, the gap 11, and the outside of the top end of the lower shell 4. The fixing ring 5 is made of rubber. The height of the fixing ring 5 is greater than the height of the gap 11. The top and bottom of the fixing ring 5 are both provided with stainless steel cable ties 13. The fixing ring 5 and the stainless steel cable ties 13 are provided to strengthen the sealing effect between the upper shell 3 and the lower shell 4.

[0028] The installation and disassembly process of the utility model is as follows:

[0029] Select upper shell 3, lower shell 4 and fixing ring 5 of appropriate size;

[0030] A flow meter ring 7 is sleeved inside the upper housing 3, and a connecting rod 9 passes through the connecting rod mounting hole 8 on the side wall of the flow meter ring 7 and the connecting rod mounting hole 8 on the side wall of the upper housing 3 in sequence, and then the end thereof is fixedly connected to a digital display meter 10;

[0031] The fixing ring 5 is sleeved on the outer side of the bottom end of the upper shell 3, the gap 11, and the outer side of the top end of the lower shell 4. The gap 11 is configured according to actual conditions;

[0032] The first mounting flange 6 is fixedly connected to the gate valve 1, and the second mounting flange 12 is fixedly connected to the dome valve 2;

[0033] During disassembly, first remove the fixing ring 5, and then disassemble the first mounting flange 6 and the gate valve 1, and the second mounting flange 12 and the dome valve 2 respectively.

[0034] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes. The implementation modes can still be changed within the knowledge scope of ordinary technicians in the field. 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.
