The utility model discloses can accurate impact impeller, sensitivity is high, and can protect change epaxial bearing exempt from rivers spatter into and by the corrosion.
Description
Technical field
The utility model relates to fire control equipment field, particularly relates to a kind of water flow indicator.
Background technology
Water flow indicator is installed on the spray piping of a protected field, is to monitor current action.During use, without the need to the flow of quantitative measurment flowing water, and only need reflect the mobility status of water qualitatively.Normally impact impeller by flowing water, to observe wheel rotation situation to judge the mobility status of water.And when practical application, but often encounter some problems like this: when 1, flowing water pressure and flow are not very large, or when the shock point of flowing water departs from impeller, and will be very not obvious during wheel rotation, giving to observe increases difficulty; 2, flowing water is when impacting impeller, easily sputters, when dropping down onto the bearing of rotating shaft bearing, and easy corrosion bearing.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of water flow indicator, accurately can impact impeller, highly sensitive, and the bearing in rotating shaft can be protected to exempt from current to be splashed into and by corrosion.
For achieving the above object, the technical solution of the utility model is: a kind of water flow indicator, comprise housing, housing side is provided with observation platform, access panel is had at observation platform internal fixtion, heart place is provided with rotating shaft in the housing, rotating shaft is fixedly connected with helical runner by flat key, rotating shaft one end is supported by the head bearing on upper bracket through after upper division board, the rotating shaft other end is supported by the lower bearing on lower carriage through after lower division board, sealed by upper O-ring seal between upper division board and rotating shaft, to be sealed by lower seal between division board and rotating shaft down, housing side is provided with water inlet, water inlet is fixedly connected with reducer pipe, reducer pipe end is connected with fair water fin, housing opposite side is provided with water delivering orifice.
The beneficial effects of the utility model are:
1, increased the surge pressure of current by reducer pipe, more accurately poured on helical runner by fair water fin, highly sensitive, when judging the mobility status of current more for convenience.
2, the setting of upper division board and lower division board, prevents impact be sputtered onto in head bearing and lower bearing to the current on helical runner and make its corrosion, can ensure the normal operation of rotating shaft for a long time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: housing 1, observation platform 2, access panel 3, rotating shaft 4, flat key 5, helical runner 6, upper division board 71, lower division board 72, upper bracket 81, lower carriage 82, head bearing 91, lower bearing 92, upper O-ring seal 101, lower seal 102, water inlet 111, water delivering orifice 112, reducer pipe 12, fair water fin 13.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As Fig. 1, shown in Fig. 2, a kind of water flow indicator, comprise housing 1, housing 1 side is provided with observation platform 2, access panel 3 is had at observation platform 2 internal fixtion, heart place is provided with rotating shaft 4 within the case 1, rotating shaft 4 is fixedly connected with helical runner 6 by flat key 5, rotating shaft 4 one end is supported by the head bearing 91 on upper bracket 81 through after upper division board 71, rotating shaft 4 other end is supported by the lower bearing 92 on lower carriage 82 through after lower division board 72, sealed by upper O-ring seal 101 between upper division board 71 and rotating shaft 4, sealed by lower seal 102 between lower division board 72 and rotating shaft 4, housing 1 side is provided with water inlet 111, water inlet 111 place is fixedly connected with reducer pipe 12, reducer pipe 12 end is connected with fair water fin 13, housing 1 opposite side is provided with water delivering orifice 112.
Principle of work of the present utility model is: current enter through water inlet 111, inflow bore is reduced by reducer pipe 12, to increase the surge pressure of current, accurately pour on helical runner 6 through fair water fin 13 again, helical runner 6 is rotated, by the access panel 3 i.e. observable in observation platform 2, thus judge the mobility status of current.Upper division board 71 and the setting of lower division board 72, prevent impact be sputtered onto in head bearing 91 and lower bearing 92 to the current on helical runner 6 and make its corrosion, can ensure the normal operation of rotating shaft 4 for a long time.
