Pad is provided with between described spring positioning step and graduated glass.Can avoid occurring, because of graduated glass and the different gap of bringing of flow meter body expanded by heating distortion, ensureing sealing effect.
In the described flow meter body of described fixed base side, be provided with lining, described flow meter body inwall is provided with lining restraining groove.Lining can prevent fixed base from coming off, and increases the fastness that it connects.
Seal ring is provided with between described lining and described flow meter body inwall.Its sealing effect of further reinforcement.
Fixed base locating slot is provided with in described flow meter body.The slip of fixed base can be limited, ensure the corresponding relation between camber of spring and flow scale.
Described flow meter body outer wall in described loose joint nut is provided with circular groove, in circular groove, is provided with cushion rubber.Improve sealing effect when being connected with water-collecting machine.
The utility model has the advantages that: compact, can quick mounting connect, flow instruction is accurate, convenient reading.

Embodiment
Embodiment:
Consult Fig. 1-5, for a kind of flowmeter, be connected between the outlet of floor heating return pipe and water-collecting machine, comprise the flow meter body 1 of hollow tubular, and the graduated glass 4 laid respectively in flow meter body 1, spring 5, buoy 6, one end of flow meter body 1 is provided with the loose joint nut 2 be connected with water-collecting machine, the other end is provided with the outside thread 3 exporting with return pipe and be connected, spring positioning step 8 is provided with in the flow meter body 1 of loose joint nut 2 side, fixed base 7 is provided with in the flow meter body 1 of outside thread 3 side, in the flow meter body 1 of graduated glass 4 between fixed base 7 and spring positioning step 8, flow meter body 1 is provided with scale form 10, O type circle 9 is respectively equipped with between graduated glass 4 at scale form 10 two ends and flow meter body 1 inwall, buoy 6 is positioned at the graduated glass 4 of fixed base 7 side, spring 5 is between buoy 6 and spring positioning step 8.The two ends of spring 5 respectively densification five are enclosed, and form tight structure, can to ensure that under stressed situation two ends still can be stablized and be positioned on buoy 6 and spring positioning step 8.In loose joint nut 2, be provided with jump-ring slot 11, the outer wall of flow meter body 1 is provided with jump-ring slot 12, in jump-ring slot 11 and jump-ring slot 12, be provided with jump ring 13.Pad 14 is provided with between spring positioning step 8 and graduated glass 4.In the flow meter body 1 of fixed base 7 side, be provided with lining 15, flow meter body 1 inwall is provided with lining restraining groove 16.Seal ring 17 is provided with between lining 15 and flow meter body 1 inwall.Fixed base locating slot 18 is provided with in flow meter body 1.Flow meter body 1 outer wall in loose joint nut 2 is provided with circular groove 19, in circular groove 19, is provided with cushion rubber 20.
