Abstract
The utility model discloses a preventing frostbite water meter relating to the technical field of water supply and sewerage. The utility model mainly comprises a shell body, a machine core, a propeller, a rubber ball, a machine core seat, and a shell body cover. The rubber ball is arranged between the inner side of the bottom surface of the shell body and the machine core seat. The utility model has the advantages of simple structure and low cost, and therefore, the preventing frostbite water meter really is not damaged under the condition of severe coldness and frost.
Description
The present invention is a kind of anti-bursting by freezing water meter that relates to the plumbing field.
In general, every need all are equipped with water meter with the various buildingss and the residential houses of tap water, in order to the water yield of metering consumption.At present, adopt wet-type meter mostly, a major defect of this table is that often bursting by freezing--watch crystal breaks easily in the winter of severe cold, causes and leaks; Plastic member in the movement damages or distortion, causes water meter malfunctioning or measure inaccurate.
Purpose of the present invention is exactly in order to overcome above-mentioned drawback, even provide for people under a kind of freezing climatic condition of severe cold, and the also anti-bursting by freezing water meter of unlikely damage.
The objective of the invention is by between inboard, housing bottom surface and core base, settling a rubber ball to realize.
Describe structure of the present invention and technical characteristic in detail below in conjunction with accompanying drawing.Fig. 1 is the anti-bursting by freezing water meter structure figure of the present invention.Among the figure:
1--protecting cover (being made of plastics) 2--case lid
3--glass 4--packing ring (making) by rubber
5--housing (pig iron founding forms) 6--movement
7--propeller (being made of plastics) 8--core base (plastics are made)
9--mesh 10--rubber ball
Be mounted with rubber ball 10 between the inboard, bottom surface of housing 5 and the bottom surface of core base 8; The bottom surface of core base 8 is processed with mesh 9; The movement 6 that propeller 7 is housed is installed in above the core base 8; The packing ring 4 that is equipped with suitable for reading of housing 5; Be equipped with watch crystal 3 on the packing ring 4; Case lid 2 and housing 5 suitable for reading with the screw thread wringing fit in case leak; Protecting cover 1 is in order to protection watch crystal 3.Mandatory declaration to be movement 6 identical with the water meter movement that circulates on the market, the gear set sum counter that it is made by some plastics is formed.
Fabrication and processing of the present invention and known general water meter are similar, do not repeat them here.
Anti-bursting by freezing principle of the present invention now is described in detail in detail.When the winter of severe cold, water meter was freezing, because the ice cube volume ratio water after solidifying is big, so tend to burst watch crystal; The infringement movement, even cause the propeller torsional deformation and make water meter malfunctioning.Owing to be mounted with rubber ball 10 between the bottom surface of inboard, the bottom surface of housing 5 of the present invention and core base 8, in fill air rubber ball have very big retractility, so freezing back volume augmenting portion at first is expanded to the rubber ball " territory " with maximal dilation, thereby improved the distribution of expansive force, extenuated the expansive force of parts such as movement, glass, thereby can not damage.
Obviously, the present invention is simple in structure, and is with low cost, even a kind of really anti-bursting by freezing water meter that also can not damage under the freezing situation of severe cold.
