Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water meters, and more specifically, to an anti-freezing water meter. Background Art
[0002] A water meter is a device for measuring water consumption; currently, the water meters on the market mainly include a housing and a movement assembly installed inside the housing, and the housing is provided with a water inlet and a water outlet; when water flows into the water meter through the water inlet and flows out from the water outlet, the water meter can measure the amount of water flowing through the water meter; however, the current water meters on the market do not have the function of anti-freezing. Therefore, when the water meter is applied to a cold environment, the water inside the water meter will freeze and cannot flow, which will affect the normal water use of users and the measurement of the water meter, and will also cause the water meter to freeze and crack. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide an anti-freezing water meter, which can avoid affecting the normal water use of users and the measurement of the water meter, and can also avoid the water meter from freezing and cracking.
[0004] The utility model provides an anti-freezing water meter, which includes a housing assembly and a movement assembly; characterized in that: the housing assembly includes an inner housing and an outer housing, and the inner housing is fixed inside the outer housing; a closed isolation cavity is formed between the inner housing and the outer housing, and the movement assembly is installed inside the inner housing.
[0005] After adopting the above structure, the utility model can effectively reduce the heat conduction between the inside and outside of the housing assembly through the setting of the inner housing and the outer housing, and a closed isolation cavity is formed between the inner housing and the outer housing. Therefore, when the water meter is applied to a cold environment, it can effectively prevent the water inside the water meter from freezing and unable to flow, thereby avoiding affecting the normal water use of users and the measurement of the water meter, and can also avoid the water meter from freezing and cracking.
[0006] In a possible implementation manner, the isolation cavity is filled with an anti-freezing medium; after filling the isolation cavity with the anti-freezing medium, it can further prevent the heat exchange between the inner side of the inner housing and the outer side of the outer housing, thereby further playing an anti-freezing effect on the inside of the water meter to prevent the water flowing through the inside of the water meter from freezing; in addition, the anti-freezing medium can be a powdery, liquid, colloidal or solid foam formed anti-freezing medium.
[0007] In a possible implementation, a through hole communicating with the isolation cavity is provided at the bottom of the outer housing. The through hole is used for filling the anti-freezing medium into the isolation cavity, and a sealing structure is provided at the through hole. After adopting this structure, the anti-freezing medium can be filled into the heat insulation cavity through the through hole, which brings convenience to the process of filling the anti-freezing medium into the isolation cavity. In addition, through the setting of the sealing structure, it is possible to prevent the anti-freezing medium from leaking out of the isolation cavity.
[0008] In a possible implementation, the sealing structure includes a bolt and a sealing ring. The sealing ring is sleeved outside the screw part of the bolt. The screw part of the bolt is threadedly connected to the hole wall of the through hole. The sealing ring abuts against the outer housing and the head of the bolt. The sealing ring is used to seal the gap between the bolt and the outer housing to block the leakage of the anti-freezing medium. After adopting this structure, after the screw part of the bolt is threadedly connected to the hole wall of the through hole, the sealing ring can seal the gap between the bolt and the outer housing to block the leakage of the anti-freezing medium, that is, it can make the anti-freezing medium be reliably filled in the isolation cavity.
[0009] In a possible implementation, the outer housing includes a front housing and a rear housing, and the joint of the front housing and the rear housing is welded and fixed and sealed. After adopting this structure, the outer housing can reliably and conveniently wrap the inner housing, that is, it is convenient to arrange the inner housing inside the outer housing.
[0010] In a possible implementation, the anti-freezing medium is solid or liquid. Through the setting of the anti-freezing medium, it can further play an anti-freezing effect on the inside of the water meter to avoid the water flowing through the inside of the water meter from freezing. In addition, the anti-freezing medium can be in the form of powder, liquid, gel or solid foam. In addition, the solid anti-freezing medium can be in the form of powder or solid foam. The liquid anti-freezing medium can be in the form of antifreeze or gel. BRIEF DESCRIPTION OF THE DRAWINGS
