Abstract
The utility model discloses a main and auxiliary water meter long in service life. The main and auxiliary water meter long in service life comprises a shell. The shell comprises a first flow channel and a second flow channel. A large water meter body is arranged in the first flow channel, and a small water meter body is arranged in the second flow channel. A valve element is arranged behind the large water meter body in the first flow channel in the water flow direction. The valve element comprises a fixed portion and a sliding portion. The fixed portion is fixed to the shell. An outlet of the second flow channel is located on the rear side of the valve element. A plug matched with the outlet of the second flow channel is arranged on the sliding portion. When the sliding portion is pushed open, the plug seals the outlet of the second flow channel. When the water flow of the main and auxiliary water meter is small, the valve element is closed, water flows through the second flow channel, and the small water meter body works; when the water flow is increased, the water pressure pushes the sliding portion to move, during movement of the sliding portion, the plug on the sliding port gradually seals the outlet of the second flow channel, and water flow in the second flow channel is reduced gradually at this time; when the opening degree of the sliding portion is the largest, the water flow in the second flow channel is reduced to the minimum degree, in this way, rotation of the small water meter body can be reduced, so that the service life of the small water meter body is prolonged, and therefore the balance between the service life of the large water meter body and the service life of the small water meter body is achieved.
Description
Technical field
The utility model relates to water meter technical field, specifically a kind of long-life primary and secondary water meter.
Background technology
Compound water metre is commonly called as primary and secondary water meter, and the water meter of being planted bore by a large young waiter in a wineshop or an inn forms.The maximum flow of the measures range of tap water by water meter from small diameter watermeter minimum flow to large-diameter water meter.So it is current measurement range maximum, the water meter that flux lower limit is minimum.
The principle of work of existing primary and secondary water meter be all generally flow little time large table spool close, little table metering, and in the time that flow increases, large table spool is pushed, large table starts metering, because little table is in running order all the time, and the measuring accuracy of little table is had relatively high expectations, often when large table also meets accuracy requirement, little table causes measuring accuracy not reach requirement because of long-term overload running, the best way be when flow is large the metering of large table and little table not measure (be entering of little table, water delivering orifice can be closed), but because standoff distance between the water inlet of little table and the spool of large table is far away, adopt mechanical mechanism quite complicated, if use Electronic Control structure that the very complicated installation inconvenience of structure of water meter and cost are improved.
Summary of the invention
The utility model is for prior art deficiency, a kind of long-life primary and secondary water meter is provided, and this primary and secondary water meter can reduce the flow of little table in the time that large table spool is opened, and reduces the working time of little table, thereby improve the serviceable life of little table, reach the balance of little table and large table mission life.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of long-life primary and secondary water meter, comprise housing, described housing comprises first flow and the second runner, in described first flow, be provided with large table, in described the second runner, be provided with little table, be provided with spool along large table rear side in first flow described in water (flow) direction, described spool comprises fixed part and sliding part, described fixed part is fixed on described housing, described the second runner exit is positioned at described spool rear side, on described sliding part, be provided with the plug coordinating with described the second runner exit, in the time that described sliding part is pushed open, described plug is by described the second runner exit shutoff.This primary and secondary water meter is in the time of work, when discharge is little, spool is closed, water flows through little water meter work from the second runner, when flow increases, the motion of water pressure pushing sliding part, along with the increase gradually of discharge, plug when sliding part motion on sliding part is gradually by the outlet of the second runner shutoff gradually, now the current in the second runner reduce gradually, until sliding part while opening maximum the current in the second runner reduce to minimum, so just can reduce the rotation of little table, thereby extend the life-span of little table, reach the balance of little table and large table mission life.
In technique scheme, preferred, described the second runner exit place is provided with cylindrical tube, and described cylindrical tube outlet coordinates with described plug.Owing to also having certain distance between general the second runner exit and sliding part, therefore be provided with cylindrical tube for shutoff is convenient.
The utility model compared with prior art, there is following beneficial effect: this primary and secondary water meter of the utility model can reduce the flow of little table in the time that large table spool is opened, reduce the working time of little table, thereby improve the serviceable life of little table, reach the balance of little table and large table mission life.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 3, a kind of long-life primary and secondary water meter, comprise housing 1, described housing 1 comprises first flow 11 and the second runner 12, in described first flow 11, be provided with large table 2, in described the second runner 12, be provided with little table 3, be provided with spool 4 along large table rear side in first flow described in water (flow) direction 11, described spool 4 comprises fixed part 41 and sliding part 42, between described fixed part 41 and sliding part 42, be provided with spring 44, described fixed part 41 is fixed on described housing 1, described the second runner 12 outlets are positioned at described spool 4 rear sides, on described sliding part 42, be provided with described the second runner 12 and export the plug 43 coordinating, in the time that described sliding part 42 is pushed open, described the second runner 12 is exported shutoff by described plug 43.This primary and secondary water meter is in the time of work, when discharge is little, spool 4 is closed, water flows through little water meter work from the second runner 12, when flow increases, water pressure pushing sliding part 4 moves, plug 43 when sliding part 42 moves on sliding part 42 is gradually by the outlet of the second runner 12 shutoff gradually, now the current in the second runner 12 reduce gradually, until sliding part 42 while opening maximum the current in the second runner 12 reduce to minimum, so just can reduce the rotation of little table 3, thereby extend the life-span of little table 3, reach the balance of little table 3 and large table 2 mission life.
Between general the second runner 12 outlets and sliding part 42, also have certain distance, convenient for shutoff, described the second runner 12 exits are provided with cylindrical tube 5, and described cylindrical tube 5 outlets coordinate with described plug 43.
