Description

[0001] This application is a divisional application of the utility model patent with application number 2024219607551, application date August 14, 2024, entitled "A processing equipment for producing integrated water meter valve control shells". Technical Field

[0002] This utility model relates to the field of water meter processing technology, specifically to an integrated water meter valve control housing. Background Technology

[0003] A water meter consists of a valve control housing and inlet and outlet ports connected to both sides of the valve control housing. Existing water meter valve control housings are typically welded structures, such as a left-right welded structure consisting of two halves of the housing welded together, or a bottom welded structure consisting of a sealing end cap welded to one end of the housing. However, welding structures require more processing steps, resulting in higher costs and slower processing efficiency.

[0004] Patent number CN219211368U provides a steel pipe sealing machine for automotive air conditioning brackets, which can achieve integrated sealing of steel pipe ends, is simple to operate, and has high work efficiency. Considering the shortcomings of existing water meter valve control shell welding processes, which involve many steps and are slow, if this improved equipment is applied to the integrated sealing of water meter shells, it will greatly improve work efficiency, save costs, and the integrated sealed shell will also have better sealing performance.

[0005] When this patent was actually applied to sealing water meter casings, some drawbacks were also discovered. Due to the lack of a positioning mechanism, the clamping length of the casing needs to be manually measured before clamping can be performed so that the sealing mold can contact the casing port, which is inconvenient. In addition, the sealing of water meter casings requires a smooth and flat surface. Therefore, before sealing, personnel need to grind the casing port on a grinder to remove burrs before transferring it to the sealing machine for sealing. This is time-consuming and labor-intensive, reducing the sealing efficiency of the casing. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing an integrated water meter valve control housing with an integrated sealing port, simplifying the process, facilitating use, and greatly improving the sealing efficiency and airtightness of the housing.

[0007] This utility model is achieved through the following technical solution: an integrated water meter valve control shell, comprising a longitudinal shell, the bottom of the shell being an integrated sealing structure, the top of the shell having an opening and a first external thread, a valve cover being hinged inside the top opening of the shell, an outlet pipe and an inlet pipe being welded to the left and right sides of the shell respectively, both the inlet pipe and the outlet pipe having a second external thread at their ends, and a valve being provided on the inlet pipe.

[0008] This design features an integrated seal at the bottom of the casing, eliminating the need for welded structures and providing superior sealing. The integrated sealing method also improves operational efficiency. A ball valve is installed on the inlet pipe, eliminating the need for external valves and saving users costs.

[0009] As an optimization, the inlet pipe includes a main pipe and a threaded connector, and the valve includes a valve seat and a valve core installed in the valve seat. The main pipe and the valve seat are integrally cast. One end of the threaded connector is threaded to the end of the valve seat away from the main pipe, and the other end of the threaded connector is provided with a second external thread. The diameter of the threaded connector at the end near the valve seat is larger than the diameter at the end away from the valve seat. This optimized solution integrally molds the main pipe and the valve seat, avoiding loosening defects at the connection between the valve and the main pipe. The threaded connector converts the valve seat port into a standard interface, facilitating connection with other pipe fittings.

[0010] As an optimization, two connecting plates are fixedly attached to the side wall of the housing. The two connecting plates are symmetrically arranged on the front and rear sides of the longitudinal housing, and bolt holes are provided on the connecting plates. This facilitates the fixed installation of the housing.

[0011] The beneficial effects of this utility model are as follows: the shell adopts a longitudinal shell structure with integrated sealing by processing equipment, which has better sealing performance. At the same time, the integrated sealing method improves operation efficiency and saves costs. The inlet pipe has an integrally formed valve, eliminating the need for an external valve and further saving user costs. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figure 7 As shown, an integrated water meter valve control housing includes a longitudinal housing 11. The bottom of the housing 11 is an integrated sealing structure. In this embodiment, the sealing structure is formed by processing equipment for the integrated water meter valve control housing. The top of the housing has an opening and a first external thread 111. A valve cover 113 is hinged inside the top opening of the housing. A water outlet pipe 12 and a water inlet pipe 13 are welded to the left and right sides of the housing, respectively. The ports of the water inlet pipe 13 and the water outlet pipe 12 are both provided with a second external thread 112. A valve 14 is provided on the water inlet pipe 13.

[0023] The water inlet pipe 13 includes a main pipe 131 and a threaded connector 132. The valve 14 includes a valve seat 141 and a valve core 142 installed in the valve seat. The main pipe 131 and the valve seat 141 are integrally cast. One end of the threaded connector 132 is threadedly connected to the end of the valve seat 141 away from the main pipe. The other end of the threaded connector 132 is provided with a second external thread 112. The diameter of the threaded connector at the end near the valve seat is larger than the diameter of the threaded connector at the end away from the valve seat.

[0024] Two connecting plates 15 are fixedly connected to the side wall of the housing 11. The two connecting plates 15 are symmetrically arranged on the front and rear sides of the housing, and bolt holes are opened on the connecting plates.

[0025] like Figures 1-6As shown, a processing equipment for producing integrated water meter valve control shells includes a chassis 1, on which a shell clamping and rotating mechanism 8 is fixed. The shell clamping and rotating mechanism 8 clamps a shell 11 and drives the shell 11 to rotate. A sealing mechanism 7 and a heating mechanism 5 are respectively provided on the left and right sides of the shell clamping and rotating mechanism 8. It also includes a grinding mechanism 6, which is arranged on the same side and in the vertical direction.

[0026] Specifically, the chassis 1 is equipped with an electrical control box 10 that controls the operation of the housing clamping and rotating mechanism 8, the grinding mechanism 6, the heating mechanism 5, and the sealing mechanism 7. The housing clamping and rotating mechanism 8 is used to clamp the cylindrical housing 11 and can drive the housing to rotate. In this embodiment, the housing clamping and rotating mechanism 8 is the rotating mechanism in patent number CN219211368U. The driving device in the housing clamping and rotating mechanism 8 can be a drive motor and a reducer for direct drive, or a belt drive structure with a drive motor and a pulley as in patent number CN219211368U can achieve the same function. It will not be elaborated on here.

[0027] The grinding mechanism 6 and the heating mechanism 5 both move along the left-right and up-down directions on the housing 1 via the first sliding mechanism 3, and respectively grind and heat the end of the housing 11. The sealing mechanism 7 moves along the left-right direction on the housing 1 via the second sliding mechanism 4, and seals the end of the housing 11.

[0028] The housing 1 has a first slide rail 2 extending in the left-right direction fixedly connected inside, and an elongated hole is opened on the top of the housing 1. The first sliding mechanism 3 includes a first slide block 31 slidably connected to the first slide rail 2, a second slide rail 32 fixedly connected to the first slide block 31, and a second slide block 33 slidably connected to the second slide rail 32. The second slide rail 32 is vertically arranged. A first telescopic cylinder 34 for driving the first slide block 31 to slide left and right is fixedly installed on the right side of the housing 1. A second telescopic cylinder 35 for driving the second slide block 33 to slide up and down is fixedly installed on the top of the second slide rail 32. The grinding mechanism 6 and the heating mechanism 5 are both installed on the second slide block 33.

[0029] Specifically, the heating mechanism 5 is slidably mounted on the second slide block 33 in the front-to-back direction, and the left side wall of the second slide block 33 is provided with a sliding groove extending in the front-to-back direction. The heating mechanism 5 includes a heater 51 and an annular heating coil 52. The upper and lower outer walls of the heater 51 are fixed to sliders, and the heater 51 is slidably connected to the sliding groove through the sliders, which facilitates the adjustment of the front-to-back position of the heating mechanism 5 so that the housing 11 can be inserted into the heating coil 52 for induction heating of the housing.

[0030] Specifically, the grinding mechanism 6 is located below the heating mechanism 5. The grinding mechanism 6 is fixed to the second slide block 33. The grinding mechanism 6 includes a support rod 61 and a grinding disc 62 mounted at the end of the support rod. The support rod 61 is fixed to the left side wall of the second slide block 33 and extends in a left-right direction. The grinding disc 62 is detachably mounted on the left end of the support rod 61. The grinding mechanism 6 moves to the left along the first slide rail 2 so that the grinding disc 62 contacts the end of the housing 11. A receiving tray 63 is provided below the grinding disc 62, and the receiving tray 63 is detachably connected to the support rod 61. In this embodiment, both the grinding disc 62 and the receiving tray 63 are fixed to the support rod 61 by bolts.

[0031] The second sliding mechanism 4 includes a third slide block 41 slidably connected to the first slide rail 2. The left side of the housing 1 is provided with a third telescopic cylinder 42 that drives the third slide block 41 to slide left and right. The sealing mechanism 7 is installed on the third slide block 41.

[0032] Specifically, the sealing mechanism 7 includes a motor 71 fixed on the third slide block 41. The output end of the motor 71 extends upward to the outside of the housing 1. A turntable 72 is fixedly connected to the upper end of the output end of the motor 71. A mounting base is fixedly connected to the turntable 72. A push block 76 is installed in the mounting base. The sealing mechanism 7 moves to the right along the first slide rail 2 so that the right end face of the push block 76 contacts the end of the housing 11. The motor 71 rotates to drive the right end face of the push block 76 to rotate to form a circular rotation trajectory.

[0033] The mounting base includes a base plate 73 fixed to the turntable 72, a vertical connecting plate 74 fixed to the base plate 73, a connecting block 75 slidably connected to the right side of the connecting plate 74, the connecting block 75 slidingly moving up and down along the connecting plate 74, a positioning bolt for fixing the connecting block 75 screwed to the left side of the connecting plate 74, and an installation groove opened on the right side of the connecting block 75, the push block 76 being detachably installed in the installation groove.

[0034] Specifically, the connecting block 75 and the connecting plate 74 are slidably connected by an upper and lower extending dovetail groove structure. The positioning bolt and the connecting plate 74 are threaded together, with the end of the positioning bolt extending into the dovetail groove to tighten the connecting block 75, thereby fixing the connecting block 75. A fastening bolt for fixing the push block 76 is screwed to the top of the connecting block 75, with the lower end of the fastening bolt extending into the mounting groove to tighten the push block 76, thereby fixing the push block.

[0035] A support plate 91 is fixedly connected to the top of the housing clamping and rotating mechanism 8. A vertically arranged fourth telescopic cylinder 9 is fixed on the support plate 91. The telescopic end of the fourth telescopic cylinder 9 passes downward through the support plate 91 and contacts the end of the housing 11. The telescopic end of the fourth telescopic cylinder 9, the sealing mechanism 7, and the grinding mechanism 6 move along the same straight line. In this embodiment, the support plate 91 is fixed to the front side of the housing clamping and rotating mechanism 8 and extends in the front-rear direction. The fourth telescopic cylinder 9 is fixed to the top front end of the support plate 91.

[0036] Working principle: Insert the housing 11 into the clamping port of the housing clamping and rotating mechanism 8, drive the extension end of the fourth telescopic cylinder 9 to extend downward, manually adjust the clamping length of the housing 11 so that the end of the housing 11 and the extension end of the fourth telescopic cylinder 9 come into contact to complete the positioning of the clamping length of the housing. At this time, the housing clamping and rotating mechanism 8 clamps the housing 11, and at the same time the extension end of the fourth telescopic cylinder 9 retracts.

[0037] The first sliding mechanism 3 is activated, and the first sliding block 31 is driven to slide to the left by the first telescopic cylinder 34, so that the grinding disc of the grinding mechanism 6 is close to the end of the housing. The second sliding block 33 is driven to slide up and down by the second telescopic cylinder 35 to adjust its position, so that the grinding disc 62 and the end of the housing 11 come into contact. The housing clamping and rotating mechanism 8 drives the housing 11 to rotate, thereby realizing the grinding of the end of the housing by the grinding disc.

[0038] The first telescopic cylinder 34 drives the first slide block 31 to slide to the left again, bringing the heating plate 52 of the heating mechanism 5 closer to the end of the housing 11. The second telescopic cylinder 35 drives the second slide block 55 to slide up and down to adjust its position, so that the housing 11 is located at the center of the heating plate 52. The heating mechanism 5 is adjusted back and forth so that the end of the housing 11 is inserted into the heating plate 52 and heated to a red-hot state. The heating mechanism 5 is then reset, and at the same time, the first telescopic cylinder 34 drives the first slide block 41 to slide to the right to reset.

[0039] The second sliding mechanism 4 is activated, and the third sliding block 41 is driven to slide to the right by the third telescopic cylinder 42, so that the push block 76 of the sealing mechanism 7 contacts the end of the housing 11. The housing clamping and rotating mechanism 8 drives the housing 11 to rotate, and the motor 71 is started. The motor 71 drives the turntable 72 to rotate, so that the push block 76 moves in a circular trajectory, realizing the one-piece sealing of the end of the housing 11.
