Problems solved by technology
[0004] The purpose of the present invention is to provide a volumetric water meter with a pressure overload protection structure, which has the advantages of pressure overload protection, and solves the problem that the volumetric water meter lacks pressure overload during use because it does not have the function of pressure relief. Protection, when the internal water pressure is high, it is prone to rupture and damage, which leads to the problem of short service life of the volumetric water meter

Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] see Figure 1-5 , a volumetric water meter with a pressure overload protection structure, comprising a meter body 1, the top of the meter body 1 is fixedly connected with a bearing ring 6, and the top of the bearing ring 6 is fixedly connected with a dial 7, through the dial 7, it is convenient to observe the volume For the water flow rate of the type water meter, the top of the back surface of the dial 7 is movably connected with a cover 10. The cover ...

The invention discloses a volumetric water meter with a pressure overload protection structure. The water meter comprises a meter body, the top of the meter body is fixedly connected with a bearing ring, the top of the bearing ring is fixedly connected with a dial plate, the top of the back surface of the dial plate is movably connected with a cover body, and the left side of the top of the frontsurface of the cover body is fixedly connected with a positioning block. Through cooperative use of a bypass water pipe, a pressure relief hole, a lifting column, a supporting spring, a placing plate,a rotating ring disc, a water outlet, a supporting ring, a rotating screw rod, a bearing seat, a lifting plate, a sealing ball, a valve plate, a connecting rod and a threaded sleeve,and pressure overload protection can be conducted on the volumetric water meter, so the service life of the volumetric water meter is longer, and the problems that in the using process of the volumetric water meter, due to the fact that the volumetric water meter does not have the pressure relief function, the volumetric water meter lacks pressure overload protection, when the water pressure borne by the interiorof the volumetric water meter is large, the volumetric water meter is extremely prone to breakage and damage, and the service life of the volumetric water meter is short are solved.
Description
technical field [0001] The invention relates to the technical field of water meters, in particular to a volumetric water meter with a pressure overload protection structure. Background technique [0002] Water meters are instruments for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. Then choose the water meter with the specification that the common flow is closest to this value as the first choice. [0003] The volumetric water meter is installed in the pipeline, and it is composed of some known volume chambers that are filled and discharged fluid one by one and the water meter is composed of a fluid-driven mechanism, or a quantitative discharge water meter for short. The volumetric water meter generally adopts a piston structure; and The speed type water meter is different. The volume type water meter measures the actual volume of the fluid passing through t...
