Description

Technical Field

[0001] The invention relates to the technical field of bidirectional water meter, in particular to a bidirectional water meter with an accuracy of L position. Background Art

[0002] A bidirectional water meter is an instrument for measuring water flow, mostly the cumulative flow of water. It is generally divided into two categories: volumetric water meter and velocity water meter. It originated in the United Kingdom, and the development of water meters has a history of nearly two hundred years. When selecting the specifications of a water meter, you should first estimate the size and range of the flow rate used under normal circumstances, and then choose the water meter with the specification that is closest to the common flow rate as the first choice. The bidirectional water meter can measure the water inflow and outflow at the same time, thereby improving the metering efficiency of the water meter. In the representation method of the water meter, the L-position bidirectional water meter is usually used to represent the flow meter, which is part of the water meter symbol. For example, in the symbol LX on the water meter drawing, L represents the flow meter, and X may represent a specific water meter type or function. This representation method is used to identify the basic type of water meter and possible functions or installation methods;

[0003] When a two-way water meter is in use, the water flow is usually measured by means of gear meshing and rotating. This causes multiple gears to become stuck when used in meshing for a long time, thus affecting the metering accuracy of the device. At the same time, when a two-way water meter is in use, it is impossible to improve the tightness and sealing of the connection between the water meter and the external water pipe. As a result, when external water enters the water meter, it is easy for the external water to leak from the water inlet and outlet of the water meter, thus affecting the water metering effect. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a two-way metering water meter with an accuracy of L position, wherein external lubricating oil can be poured into the interior of the lubrication box through the liquid inlet pipe, and the lubricating oil in the lubrication box can be adsorbed by the adsorbing cotton, so that the lubricating oil can be stored in the adsorbing cotton. When the water meter is measuring water, the rotation of the second reduction gear is used to drive the movable rod to rotate. Since the flapping plate is in contact with the surface of the movable rod, when the movable rod rotates, the flapping plate can utilize the elasticity of the second spring to rebound and slap, and the rebound of the flapping plate during the rebound and slapping can be used to drive the extrusion seat to squeeze or pull the spring, so that the extrusion seat can penetrate the hollow plate below the adsorbing cotton and enter the interior of the adsorbing cotton to squeeze the adsorbing cotton, so that the lubricating oil in the adsorbing cotton can drip from the adsorbing cotton and flow out from the inclined plate due to the extrusion. Since the inclined plate is located above the second reduction gear, the lubricating oil can drip on the surface of the second reduction gear for lubrication, so that when the water meter is measuring water, the gear set is not prone to jamming, and the water The water inlet pipe and the water outlet pipe of the meter are both connected with the external water pipe, and the joint is used to allow the external water pipe to extend into the interior of the joint to fit with the water inlet pipe and the water outlet pipe of the water meter. When the external water pipe is fitted with the water inlet pipe and the water outlet pipe, the pull plate can be pushed backwards, so that the pull plate can drive the extrusion ring and the movable plate to move together, and the elasticity of the third spring can be used to allow the movable plate to be expanded without being affected by the opening extrusion, so as to increase the diameter of the extrusion ring, so that the movable plate and the extrusion ring can fit and extrude with the connection between the water pipe, the water inlet pipe and the water outlet pipe together, and the continuous movement of the pull plate can be used to drive the limit plate and the plug plate to move, and the plug plate can be embedded in the interior of the embedding seat to fix the pull plate, and the rubber strip can be used to increase the friction force when the plug plate and the embedding seat are embedded, so that when the external water pipe is connected to the water inlet pipe and the water outlet pipe, the tightness and sealing of the water meter when connected to the water pipe can be improved, so that it can prevent the water leakage in the water pipe from affecting the water measurement of the water meter, etc., and solve the problems of gear set jamming and external water source leakage.

The impeller 14 can drive the rotating rod 13 to rotate inside the water meter 1 due to the water pressure. Due to the meshing of the first reduction gear 10 and the second reduction gear 12, the rotating rod 13 can drive the first reduction gear 10 to rotate when rotating. Through the rotation of the first reduction gear 10, it can drive the second reduction gear 12 to rotate. Since the first reduction gear 10 is connected to the flywheel 7, and the second reduction gear 12 is connected to the counter 9, the water meter 1 can measure the water according to the rotation of the impeller 14. The value measured by the water meter 1 can be displayed on the display screen 3. The two-way measurement of the water meter 1 can improve the water metering efficiency.

[0029] The water meter 1 is fixedly connected with a lubrication box 18 inside, and an adsorption cotton 16 is arranged inside the lubrication box 18.

The inner part of the joint 5 is extended to fit the water inlet pipe 8 and the water outlet pipe 4 of the water meter 1. When the external water pipe fits the water inlet pipe 8 and the water outlet pipe 4, the pull plate 35 can be pushed backward, so that the pull plate 35 can drive the extrusion ring 31 and the movable plate 30 to move together. By utilizing the elasticity of the third spring 11, the movable plate 30 is not affected by the extrusion of the opening 29, so that it can be expanded to increase the diameter of the extrusion ring 31, so that the movable plate 30 and the extrusion ring 31 can be connected with the water pipe, the water inlet pipe 8, and the water outlet pipe 4.

The rotation of the first reduction gear 10 can drive the second reduction gear 12 to rotate. Since the first reduction gear 10 is connected to the flywheel 7 and the second reduction gear 12 is connected to the counter 9, the water meter 1 can measure water according to the rotation of the impeller 14. The value measured by the water meter 1 can be displayed on the display screen 3. When the water meter 1 is measuring water, the rotation of the second reduction gear 12 can drive the movable rod 20 to rotate. Since the flapping plate 23 fits the surface of the movable rod 20, when the movable rod 20 rotates, the flapping plate 23 can utilize the elasticity of the second spring 22 to rebound and flap, and utilize the rebound of the flapping plate 23 to make the elastic plate 26 drive the extrusion seat 25 to squeeze or pull the spring, so that the extrusion seat 25 can penetrate the hollow plate 19 below the adsorption cotton 16 and enter the interior of the adsorption cotton 16 to squeeze the adsorption cotton 16, so that the lubricating oil in the adsorption cotton 16 can drip from the adsorption cotton 16 and flow out from the inclined plate 24 due to the squeezing.
