In the figure: the device comprises a shell 101, a water inlet pipe 102, a water outlet pipe 103, a partition plate 104, a discharge hole 105, a counting needle 106, a flow rate needle 107, a counting meter 108, a glass cover 109, a discharge pipe 201, a sealing plug 202 and a spring 203.

Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

As shown in fig. 1-4, a can prevent frostbite water gauge of earial drainage, includes casing 101, baffle 104 and a plurality of earial drainage groove 201, install in the casing 101 baffle 104, be equipped with a plurality of earial drainage holes 105 on the baffle 104, earial drainage hole 105 below is equipped with earial drainage groove 201, earial drainage groove 201 is interior to install sealing plug 202 and spring 203, spring 203 upper end is connected sealing plug 202, the lower extreme with earial drainage groove 201 bottom is connected.

The partition plate 104 is also provided with a counting needle 106, a counting meter 108 and a flow rate needle 107, the water consumption of a user can be obtained through the counting needle 106 and the counting meter 108, and whether the water meter leaks or not can be observed through the flow rate meter 107.

A glass cover 109 is also mounted above the spacer 104.

The clearance between the glass cover 109 and the partition plate 104 is larger than the heights of the counting needle 106 and the flow rate needle 107.

The vent hole 105 has a smaller diameter than the sealing plug 202, and the sealing plug 202 is tightly fitted to the vent groove 201.

The pressure of the spring 203 on the sealing plug 202 is greater than the water pressure in the water meter, so that the sealing plug 202 is positioned at the top end of the drainage groove 201 during normal use.

The pressure of the spring 203 on the sealing plug 202 is less than the pressure on the glass cover 109 when the tap water freezes, so that the sealing plug 202 can be driven to compress the spring 203 when the tap water freezes.

The specific working process is as follows: when the water meter is used in a normal state, because the pressure of the spring on the sealing plug is greater than the water pressure of tap water, the glass cover is filled with water, but the sealing plug is still positioned at the top end of the drainage groove as shown in fig. 3, when the temperature is reduced and the tap water begins to freeze, the space in the glass cover can be extruded due to the volume expansion of the frozen water, if the drainage groove is not provided, the copper shell around the glass cover has much higher pressure resistance than the glass cover, so the glass cover can be finally crushed, after the drainage groove is installed, because the pressure of the spring on the sealing plug is less than the pressure of the frozen water on the glass cover, the frozen tap water drives the spring to extrude, the sealing plug moves downwards as shown in fig. 4, the frozen tap water in the drainage groove balances the pressure on the glass cover, and the glass cover is protected from being crushed; when the temperature rises and the ice blocks melt, the spring resets to drive the sealing plug to move to the top end of the drainage groove due to the fact that the pressure of the spring is larger than the water pressure, the drainage process of the water meter is completed through the up-and-down movement of the sealing plug, and the frost crack of the water meter is greatly reduced.
