By adopting the water meter convenient to overhaul provided by the embodiment of the disclosure, when the water meter body 1 is replaced, a water valve is not required to be closed, only two valves 4 are required to be closed, the piston 7 on the movable column 14 is driven by the driving mechanism to move towards the direction away from the third connecting pipe 5, so that a passage is formed between the two third connecting pipes 5 and the fourth connecting pipe 6, an external water source can directly enter a user without influencing the use of the user through the water meter body 1, when the water meter body 1 is replaced, only two valves 4 are required to be opened, and the driving mechanism is reversely rotated, so that the movable column 14 can jack the piston 7 into the third connecting pipe 5 and block the third connecting pipe 5, and water flow can only flow in the water meter body 1 at this time, thereby being beneficial to realizing not only overhauling the water meter, but also continuing water supply for the user.

Alternatively, the valve 4 is a shut-off valve. Thus, the shut-off valve has the following advantages: during the whole opening and closing process, the friction force between the valve clack and the protruding surface of the valve body is smaller than that of the gate valve, so that the valve is wear-resistant; the open aspect ratio is typically only 1/4 of the valve seat safety channel and is thus much smaller than the gate valve; generally, only 1 sealing surface can be arranged on the valve body and the valve clack, so that the production and manufacturing process performance is better, and the overhaul is facilitated.

It is understood that the specific structure and operation principle of the stop valve are well known to those skilled in the art, and thus the specific structure and operation principle of the stop valve are not described in detail herein.

Optionally, the size of the piston 7 is adapted to the inner diameter of the third connecting tube 5. In this way, the piston 7 is conveniently moved into the third connecting pipe 5 under the action of the moving column 14 to seal or open the third connecting pipe 5.

Alternatively, the two moving posts 14 are provided with sleeves 15, and the tops of the sleeves 15 are fixed to the fourth connection pipe 6. Therefore, the joint between the movable column 14 and the fourth connecting pipe 6 can be plugged through the sleeve 15, so that water in the fourth connecting pipe 6 is prevented from overflowing, and the smoothness and continuity of water flow are improved.

Optionally, a waterproof sealing ring is fixedly arranged at the bottom of the sleeve 15. In this way, by providing the waterproof seal ring, the sealability between the movable column 14 and the fourth connecting pipe 6 can be further improved, the water in the fourth connecting pipe 6 can be prevented from overflowing, and the flow smoothness and consistency of the water can be improved.

Optionally, the drive mechanism comprises: the device comprises a first supporting seat 8, a second supporting seat 11, a threaded column 9 and a rotating shaft 12. The first supporting seats 8 are arranged in pairs, and the two first supporting seats 8 are respectively arranged at one sides of the two third connecting pipes 5; the second supporting seat 11 is arranged between the two first supporting seats 8, and the second supporting seat 11 is vertically arranged with the two first supporting seats 8; one end of the threaded column 9 is rotatably connected with the surface of the first supporting seat 8, and the other end penetrates through the second supporting seat 11; the rotating shaft 12 is arranged between the two first supporting seats 8, two ends of the rotating shaft 12 are respectively connected with the surfaces of the two first supporting seats 8 in a rotating way, and the rotating shaft 12 is connected with the threaded column 9 through a transmission mechanism. Thus, the surface of the first supporting seat 8 is rotationally connected with the two ends of the rotating shaft 12, so that the rotating shaft 12 can be provided with a rotating support, and the rotating shaft 12 can rotate more stably and efficiently; when the water meter body 1 needs to be maintained or replaced, the rotating shaft 12 can be rotated, the rotating shaft 12 can drive the threaded column 9 to rotate through the transmission mechanism when rotating, meanwhile, one end of the threaded column 9 penetrates through the second supporting seat 11, so that the threaded column 9 can drive the second supporting seat 11 to move upwards or downwards when rotating, the movable column 14 is driven to move towards one side of the third connecting pipe 5 or move towards one side far away from the third connecting pipe 5, the piston 7 enters the third connecting pipe 5 to seal the third connecting pipe, or the piston 7 is separated from the third connecting pipe 5 to enable the third connecting pipe 5 and the fourth connecting pipe 6 to form a circulation pipeline, water entering the water inlet of the water meter body 1 is discharged through the water outlet of the water meter body 1 after passing through the third connecting pipe 5 and the fourth connecting pipe 6, continuous water supply to a user is guaranteed, and meanwhile, replacement or maintenance of the water meter body 1 is not hindered.

Optionally, the two threaded posts 9 are both in threaded connection with the second support seat 11. In this way, when the threaded column 9 rotates, the second supporting seat 11 in threaded connection with the threaded column is driven to move upwards or downwards, so that the moving column 14 connected with the second supporting seat 11 is driven to move upwards or downwards, and the moving column 14 pushes the piston 7 into the third connecting pipe 5 and seals the third connecting pipe, or pulls the piston 7 out of the third connecting pipe 5 to open a circulation pipeline of the third connecting pipe 5.

Optionally, one end of the rotating shaft 12 penetrates the first supporting seat 8 and is connected with a rocker 16. Therefore, the rotating shaft 12 can be conveniently and rapidly rotated through the rocker 16, so that the rotating shaft 12 can drive the threaded column 9 to rotate through the transmission mechanism in the rotating process, and the second supporting seat 11 in threaded connection with the threaded column 9 is driven to move upwards or downwards, so that the third connecting pipe 5 is plugged or opened.

Optionally, the transmission mechanism comprises: a first bevel gear 10 and a second bevel gear 13. The first bevel gear 10 is connected to one end of the threaded column 9 penetrating through the second supporting seat 11; the second bevel gear 13 is fixedly installed on the outer side wall of the rotating shaft 12, and the second bevel gear 13 is in meshed connection with the first bevel gear 10. Thus, when the rotating shaft 12 is rotated by the rocker 16, the rotating shaft 12 drives the second bevel gear 13 on the outer side wall thereof to rotate, and the second bevel gear 13 drives the first bevel gear 10 in meshed connection with the second bevel gear 13 to rotate when rotating, so that the threaded column 9 connected with the first bevel gear 10 rotates and drives the threaded column 9 to rotate.

Alternatively, the second bevel gears 13 are provided in pairs with a space between the two second bevel gears 13, respectively in meshed connection with the two first bevel gears 10 attached to the threaded post 9. Thus, a transmission mechanism can be arranged at two ends of the rotating shaft 12 so as to mutually match the first bevel gear 10 and the second bevel gear 13, so that when the rotating shaft 12 is rotated by the rocker 16, the rotating shaft 12 can rotate by driving the second bevel gears 13 arranged at intervals at two ends of the rotating shaft to realize the rotation of the first bevel gear 10 which is meshed and connected with the second bevel gear 13, thereby being beneficial to efficiently and stably moving the two threaded columns 9 upwards or downwards.
