Abstract
The utility model provides a water meter shell with two compound thermoplasticity plastics that relates to a water meter shell aiming at the problems of the prior flowmeter shell on complex manufacturing technique and high cost due to being combined of a plastic material and a metal embedded assembly. The internal framework (1) of the utility model is arranged inside a modified polypropylene plastic shell body (2) and is fixed and connected with the modified polypropylene plastic shell body (2); modified polypropylene plastic connecting pipes (3) are respectively arranged on the two ends of the modified polypropylene plastic shell body (2) and are respectively molded with the modified polypropylene plastic shell body (2) into an integer. The utility model is made of two compound plastic materials, wherein, the internal framework of the shell body is made of polyphenylene plastic, polyformaldehyde plastic or nylon material, and has the advantages of strong strength, large capacity of pressure loading, strong performance of high-temperature and low-temperature resistance, small deformation, and the capacity of guaranteeing the design size; besides, the connecting pipe and the shell body are made of modified polypropylene material, thus having the advantages of high-temperature resistance, deformation-proof, and convenience for being connected with external pipes.
Description
Technical field
The utility model relates to a kind of water meter case.
Background technology
Granted publication number is the utility model patent on April 19th, 2006 for CN2773633Y, Granted publication day, a kind of " flow instrument housing " disclosed, make its manufacturing process complexity, cost height because this instrument housing is by a kind of plastic material and the metal insert is compound.
The utility model content
The purpose of this utility model provides a kind of water meter case that is composited by two kinds of thermoplasticss, and it can solve existing flow instrument housing owing to adopt a kind of plastic material and metal insert to be composited, and has manufacturing process complexity, problem that cost is high.
Poly-third plastic casing of inner frame that the utility model is made by polydiphenyl ether plastics, acetal plastic or nylon material and modification and the poly-third plastic union pipe spare of modification are formed; Described inner frame is arranged in poly-third plastic casing of modification and with poly-third plastic casing of modification fixedlys connected, and the poly-third plastic union pipe spare of described modification is separately positioned on the two ends of poly-third plastic casing of modification and becomes one with the poly-third plastic casing injection moulding of modification respectively.
The utlity model has following beneficial effect: one, the utility model adopts two kinds of plastic materials to be composited, the inner frame of its middle shell is made by polydiphenyl ether plastics, acetal plastic or nylon material, has the intensity height, the pressure that bears is big, ability high temperature resistant, low temperature is strong, deflection is little, can guarantee the advantage of design size.Two, connecting tube and housing are made by poly-third plastics of modification respectively, and not only high temperature resistant, anti-distortion also is convenient to be connected with Outer Tube simultaneously.Three, the utlity model has the advantage of simple in structure, easy processing, with low cost, long service life.
