Abstract
The utility model discloses a plastic water meter case, which comprises an inner chamber for master meter components to be mounted therein, a water inlet and an outlet communicating with the inner chamber. The pipe segment where said water inlet and outlet are located has an outward-extending thickened region opposite to the external surface of a connection pipe segment communicating with the inner chamber. The thickened region is further provided with external threads, and is 2-3 times as thick as the connection pipe segment. The utility model has advantages of simple structure and high strength of thread segment, and easy connection with metal pipes, PP-R pipes or PVE pipes.
Description
Technical field
The utility model relates to a kind of water meter case.
Background technology
Existing tap water watch shell, generally be to make by iron casting, its structure comprises inner chamber that is used to install the master meter assembly and water inlet interface, the water outlet interface that is communicated with inner chamber, existing tap water watch shell, no matter be to make by which kind of material, the spout part of its water inlet interface, water outlet interface all has external thread, connects one section by the work in copper knot and have externally threaded copper pipe on this external thread section, is connected with existing metallic water pipe with convenient.But now plastics, copper water meter case are recommended to use by country, ban use of the cast iron water meter case, so occurred on the market and the identical plastic water meter case of cast iron water meter case structure, the drawback that this plastic water meter case exists is: the wall thickness of its water inlet interface and water outlet interface thread section is identical with the wall thickness that inner chamber is communicated with pipeline section, its externally threaded pitch is identical with thread pitch on the cast iron water meter case, when being installed on the pipeline by slip-knot, because the intensity of thread segment is less relatively, its thread segment is easy to damage, and causes the duct ligation connecting portion to leak.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, thread segment intensity height, the convenient plastic water meter shell body structure that is connected with metal tube, PP-R pipe or pvc pipe.
For solving the problems of the technologies described above, the utility model comprises inner chamber that is used to install the master meter assembly and water inlet interface, the water outlet interface that is communicated with inner chamber, its design feature is that the wall thickness of the mouth of pipe section at described water inlet interface and water outlet interface place has an outward extending thickening section with respect to the outer surface of tube wall of the connection pipeline section that is communicated with inner chamber, is provided with external thread on this thickening section.
The wall thickness of described thickening section is wall thickness 2-3 times of the connection pipeline section.
On the end face of described water inlet interface and water outlet interface place spout part, be provided with the groove that is used to install O-ring seal.
The 2-3 of the thread pitch on the metal water watch shell that described externally threaded pitch is same specification doubly.
After adopting said structure, because the wall thickness of the mouth of pipe section at described water inlet interface and water outlet interface place has an outward extending thickening section with respect to the outer surface of tube wall of the connection pipeline section that is communicated with inner chamber, on this thickening section, be provided with external thread, so this thread segment intensity height.The slip-knot butt junction that is equipped with special-purpose slip-knot and adapts with slip-knot on this thread segment can be connected with metal tube, PP-R pipe or pvc pipe easily; And on the end face of described water inlet interface and water outlet interface place spout part, be provided with the groove that is used to install O-ring seal, increase the sealing property of connecting portion, avoid the duct ligation connecting portion to leak, increase the pitch of screw thread on the thread segment, further improve the installation strength of thread segment.It is simple in structure, and cost is low, is easy to install and use, and simultaneously, surface of shell is bright and clean, non-scaling, not corrosion, therefore can keep water sanitation and hygiene, be of value to health of people and current are unimpeded.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Accompanying drawing is the syndeton synoptic diagram of the utility model water meter case.
Embodiment
Plastic water meter shell body structure shown in the drawings, comprise and be used to install the inner chamber 1 of master meter assembly and the water inlet interface 8 that is communicated with inner chamber 1, water outlet interface 3, water inlet interface 8, inner chamber 1 and water outlet interface 3 are one-time formed moulding, the wall thickness of the mouth of pipe section at water inlet interface 8 and water outlet interface 3 places has an outward extending thickening section 4 with respect to the outer surface of tube wall of the connection pipeline section 2 that is communicated with inner chamber 1, the wall thickness of this thickening section 4 is wall thickness 2-3 times of connection pipeline section 2, on this thickening section 4, be provided with external thread, externally threaded pitch be the thread pitch on the metal water watch shell of same specification 2-3 doubly, further improve the installation strength of thread segment.On the end face of water inlet interface 8 and water outlet interface 3 place spout parts, also be provided with the groove 5 that is used to install O-ring seal 6, to increase the sealing property of connecting portion.The slip-knot butt junction that is equipped with special plastic slip-knot 7 and adapts with slip-knot 7 on the thread segment of water inlet interface 8, water outlet interface 3 ends can be connected with metal tube, PP-R pipe or pvc pipe easily.
