[ description of the drawings ]
The invention will be further described with reference to examples of embodiments with reference to the accompanying drawings.
Fig. 1 is an exploded view of an anti-freeze water meter according to the present invention.
Fig. 2 is a schematic structural view of an anti-freezing water meter (partially cut-away view) according to the present invention.
[ detailed description ] of the invention
Referring to fig. 1-2, an anti-freeze water meter 100 includes a water meter body 10 and a drain mechanism 20, wherein the water meter body 10 includes a case 101 and a movement gear box 102; the relief mechanism 20 comprises a relief tube 1, a guide sleeve 2, a piston 3, a spring 4 and a compression ring 5; the bleeder tube 1 is integrally connected to the watchcase 101 and is communicated with the deck gear box 102; the front end of the guide sleeve 2 extends into the movement gear box 102, and the rear end of the guide sleeve is fixed on the inner side of the bleeder tube 1; the front end of the guide sleeve 2 is positioned in the movement gear box 102 near the center of the water meter after installation. The piston 3 is inserted in the guide sleeve 2 in a left-right movable manner, the compression ring 5 is fixedly connected to the free end of the discharge pipe 1, and the spring 4 is clamped between the compression ring 5 and the piston 3.
Referring to fig. 1-2, the bleeder tube 1 comprises a small diameter tube 11 and a large diameter tube 12 connected to each other, the small diameter tube 11 is connected to the watch case 101, and a first internal thread (not shown) is provided on an inner wall ring of the small diameter tube 11; the outer wall of the guide sleeve 2 is provided with a first external thread (not shown) corresponding to the small diameter pipe 11 in a ring mode, and the guide sleeve 2 is rotationally connected with the small diameter pipe 11 through the first internal thread and the first external thread. The head of the guide sleeve 2 expands outwards to form a shoulder 21, the shoulder 21 is clamped at the inner end of the large-diameter pipe 12, and a first sealing ring 6 is arranged between the shoulder 21 and the large-diameter pipe 12. The inner wall of the tail part of the guide sleeve 2 extends towards the longitudinal axis to form a small-diameter groove 22, and the small-diameter groove 22 is matched with the outer diameter of the piston 3; two grooves 31 are formed in the tail end of the piston 3 in a surrounding mode, and a second sealing ring 7 is sleeved on the grooves 31. The head of the piston 3 is provided with a convex ring 32, the convex ring 32 is clamped on the convex shoulder 21, and the tail end of the spring 4 is clamped on the convex ring 32.
