Abstract
The utility model discloses a valve element for a mother-son water meter. The valve element comprises a fixed part and a sliding part. The sliding part is provided with an end cap. The valve element is used for being installed in a runner of a large meter of the mother-son water meter. When the valve element is opened, the sliding part moves to enable the end cap to be matched with a water outlet of a small meter so that the water outlet of a runner of the small meter can be closed slowly, accordingly, flow of the small meter can be reduced in the mother-son water meter when the valve element of the large meter is opened, the working time of the small meter is shortened, the service life of the small meter is prolonged, and the working life of the small meter and the working life of the large meter are balanced.
Description
Technical field
The utility model relates to water meter technical field, specifically a kind of spool of 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 maximum that it is current measurement range, 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 when 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 does not reach requirement because of long-term operation measuring accuracy, the best way is that large table is opened and the water inlet of little table can be closed when flow is large, 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, research and development and installation be difficulty quite, 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 not enough for prior art, a kind of spool of primary and secondary water meter is provided, the spool of this primary and secondary water meter is arranged in primary and secondary water meter can reduce the flow of little table when 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.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of spool of primary and secondary water meter, comprise fixed part and sliding part, and on described sliding part, be provided with plug.This spool is for being arranged in the runner of the large table of primary and secondary water meter, when this spool is opened, sliding part motion coordinates described plug slowly by the water delivering orifice sealing in little surface low road with the water delivering orifice of little table, in primary and secondary water meter, can when opening, large table spool reduce the flow of little table like this, 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.
In technique scheme, preferably, described fixed part comprises the plate-like piece with some through holes, on described plate-like piece, be provided with connecting link, the described connecting link other end is provided with lug boss, and described sliding part is arranged between described plate-like piece and described lug boss, between described sliding part and described lug boss, is provided with spring, the spool of employing elastic slip mode can be realized the slip of larger distance, makes the runner of plug and little table process be more prone to realize shutoff.
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 when 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.
Accompanying drawing explanation

Fig. 2 is the cut-open view of the state one of the utility model embodiment.
Fig. 3 is the cut-open view of the state two of the utility model embodiment.
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 spool of primary and secondary water meter, comprise fixed part 41 and sliding part 42, described fixed part 41 comprises the plate-like piece 411 with some through holes, on described plate-like piece 411, be provided with connecting link 412, described connecting link 412 other ends are provided with lug boss 413, described sliding part 42 is arranged between described plate-like piece 411 and described lug boss 413, between described sliding part 42 and described lug boss 413, be provided with spring 44, on described sliding part 42, be provided with plug 43.
This spool 4 is installed in primary and secondary water meter, described primary and secondary water meter comprises 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, along large table rear side in first flow described in water (flow) direction 11, be provided with described spool 4, 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 the plug 43 coordinating with described the second runner 12 outlets, when described sliding part 42 is pushed open, described plug 43 is by described the second runner 12 outlet shutoff.This primary and secondary water meter is when work, when discharge is little, spool 4 is closed, water flows through little water meter work from the second runner 12, when flow increases, 4 motions of water pressure pushing sliding part, plug 43 during sliding part 42 motion 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.
