Abstract
Description
Technical Field
[0001] This utility model relates to the field of natural gas flow meter technology, specifically a natural gas flow meter. Background Technology
[0002] A natural gas flow meter is an instrument used to measure the flow rate of natural gas. Its main working principle is to detect the mixture of natural gas and air flowing through a pipeline and calculate the actual amount of natural gas passing through the pipeline. Its working process can be divided into: detecting the gas mixture, separating the air, calculating the natural gas volume, and outputting the measurement result. Natural gas flow meters can accurately measure natural gas flow, ensuring the safe and efficient operation of production processes; monitoring natural gas usage, promptly identifying and resolving potential problems, saving energy; ensuring industrial safety and reliability, and reducing environmental pollution.
[0003] Existing natural gas flow meters are large in size and occupy a large area when installed in corners. At the same time, the flow meters are directly exposed to the outside environment, allowing dust to enter the flow meter, which can cause the flow meter dial to become blurry and affect the accuracy of the readings. Additionally, moisture can enter the flow meter and cause damage.
[0004] To address this issue, the present invention provides a natural gas flow meter that uses a retaining pin to house the flow meter body, thereby resolving the aforementioned problems. Utility Model Content

[0012] Beneficial effects
[0013] This invention provides a natural gas flow meter. Compared with the prior art, it has the following advantages:
[0014] 1. This natural gas flow meter uses a retaining rod to house the flow meter body, which reduces the footprint of the flow meter body.

Detailed Implementation
[0021] 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.
[0022] Example 1:
[0023] Please see Figure 1-3 A natural gas flow meter includes a connecting pipe 1, a cavity connecting plate 2 fixedly connected to the top end of the connecting pipe 1, the connecting pipe 1 and the cavity connecting plate 2 being in communication, a connecting seat 3 fixedly connected to the top end of the cavity connecting plate 2, a transition post 4 rotatably connected inside the connecting seat 3, a conduit 5 fixedly connected between the connecting seat 3 and the transition post 4, a branch pipe 6 fixedly connected to the outer end of the transition post 4, a sleeve 7 slidably connected to the outer end of the branch pipe 6, a flow meter body 8 fixedly connected to the outer end of the sleeve 7, a locking post 9 fixedly connected to the outer end of the cavity connecting plate 2, and the flow meter body 8 being locked inside the locking post 9. The purpose of this design is to secure the flow meter body 8 inside the retaining post 9 during installation. The retaining post 9 not only houses the flow meter body 8 but also reduces its footprint. Furthermore, housing the flow meter body 8 prevents dust and moisture from entering its interior, thus preventing dust from adhering to the outer edge of the dial and affecting the accuracy of the readings. Preventing moisture from entering also prevents the internal components of the flow meter body 8 from becoming damp and damaged.
[0024] Preferably, a backing plate 10 is fixedly connected inside the retaining post 9. A drain hole is provided at the top of the backing plate 10, and a cleaning rod 11 is rotatably connected to the top of the backing plate 10. The cleaning rod 11 is Y-shaped, and bristles 12 are fixedly connected to the top of the cleaning rod 11. The purpose of this arrangement is that in dusty environments, dust will adhere to the exterior of the flowmeter body 8. After the flowmeter body 8 is secured inside the retaining post 9, rotating the cleaning rod 11 allows the bristles 12 at the top of the cleaning rod 11 to clean the outer surface of the flowmeter body 8. The cleaned dust falls from the drain hole at the top of the backing plate 10 into the bottom of the retaining post 9. The bottom of the retaining post 9 is detachable, facilitating the cleaning of the dust.
[0025] Preferably, a barrier mesh 13 is fixedly connected to the inner wall of the clamping post 9, and a drying plate 14 is provided at the outer end of the barrier mesh 13. The drying plate 14 is fixedly connected to the inside of the clamping post 9. The purpose of this arrangement is that the drying plate 14 can absorb the humid air inside the clamping post 9, thereby drying the inside of the clamping post 9 and preventing the flow meter body 8 from getting damp.
[0026] Example 2:
[0027] Please see Figure 1-5 This embodiment provides a natural gas flow meter technical solution based on Embodiment 1: a stop rod 15 is fixedly connected to the outer end of the locking post 9, a fixing plate 16 is rotatably connected inside the stop rod 15, and a torsion spring is fixedly connected between the stop rod 15 and the fixing plate 16. The purpose of this arrangement is that after the flow meter body 8 is locked inside the locking post 9, the fixing plate 16 can fix the flow meter body 8 and prevent the flow meter body 8 from loosening.
[0028] Preferably, the outer end of the connecting pipe 1 is rotatably connected to a clamp 17, and a double-ended screw 18 is slidably connected between two corresponding clamps 17. The outer end of the double-ended screw 18 is threadedly connected to a nut 19. The purpose of this arrangement is that when fixing the connecting pipe 1 to the external pipe, the clamps 17 are used to clamp the connecting pipe 1 to the external pipe, and then the double-ended screw 18 is clamped between the two corresponding clamps 17 and fixed with the nut 19. The fixing method is simple and convenient for installation and disassembly.
[0029] Preferably, branch pipe 6 is connected to sleeve 7, and a support spring 20 is fixedly connected between branch pipe 6 and sleeve 7. The purpose of this arrangement is that, during measurement, gas enters the cavity connecting plate 2 from the connecting pipe 1, then enters the adapter column 4 from the conduit 5, and enters the flow meter body 8 from branch pipe 6 and sleeve 7. Branch pipe 6 can be retracted into sleeve 7, thus facilitating the folding and storage of flow meter body 8 into locking column 9. At the same time, the support spring 20 facilitates the adjustment of the height of flow meter body 8 during measurement, thereby facilitating measurement operation.
