Abstract
The utility model discloses a kind of watermeter flowing rate regulating valve, belong to watermeter flowing rate control technology field.It includes copper sheathing, spring, movable net and fluidic plate, and the spring is arranged in copper sheathing, and the movable net is connected through spring inner with fluidic plate；The copper sheathing right-hand member sets inside flange, and the spring is limited between copper sheathing flange and movable net left end, and the activity is uniformly arranged mesh on the net, and jet orifice is set in the fluidic plate.Compared with prior art, water meter range can be expanded using the utility model of above structure, ensures that water meter accurately measures under low flow condition.
Description
Technical field
The utility model belongs to watermeter flowing rate control technology field, and in particular to a kind of watermeter flowing rate regulating valve.
Background technology
The principle of speed water meter is that watchcase water inlet hole area is big, and water meter is slow, and water inlet hole area is smaller, the power of water slug impeller
Bigger, water meter is faster or even drips with regard to turning, and the water meter just turned that drips on the market is exactly around this principle.At present I
The execution standard GB778.1-2007/ISO4064-1 of state's water meter:2005 standard regulation Q4 are maximum stream flows, and Q3 is conventional flow,
Q2 is boundary flow, and Q1 is minimum discharge, and measurement range is determined that R more wide ranges are bigger, and R gets over small-range by Q3/Q1 ratio R
It is smaller.Therefore, in order to ensure the precision of the water meter in the case of low discharge, it would be desirable to try every possible means to improve the R values of water meter to increase
The range of big water meter.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided one kind can expand water meter range, ensure water meter
The flow control valve accurately measured under low flow condition.
The technical solution adopted in the utility model is as follows：
A kind of watermeter flowing rate regulating valve, including copper sheathing, spring, movable net and fluidic plate, the spring are arranged in copper sheathing,
The movable net is connected through spring inner with fluidic plate；The copper sheathing right-hand member sets inside flange, and the spring is defined
Between copper sheathing flange and movable net left end, the activity is uniformly arranged mesh on the net, and jet orifice is set in the fluidic plate.
The copper sheathing and movable net are cylindrical shape, and the central axis of the copper sheathing, movable net and jet orifice is the same as always
On line.
The mesh is square or slot, and the jet orifice is circular or slotted eye.
The beneficial effects of the utility model are：Using the regulating valve of said structure, when water meter reaches maximum stream flow, in water
Thrust under activity net it is fully open, do not increase crushing, when flow velocity becomes it is small when, spring-relaxation, activity net retreats, and water is from above
Jet orifice projects, and is so netted by activity and comes and goes activity adjustment water meter water inlet hole area, played a part of improving water meter range, protect
The precision of the water meter in the case of low discharge has been demonstrate,proved, ensure that the interests of water meter company, it is ensured that with the degree of accuracy of water.
Brief description of the drawings
Fig. 1 is structural representation of the utility model in maximum, the movable net full open position of current；
Fig. 2 is structural representation of the regulating valve shown in Fig. 1 in weep state.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings：
In Fig. 1-2：1st, copper sheathing, 2, spring, 3, movable net, 4, fluidic plate, 5, jet orifice.
It includes copper sheathing 1, spring 2, movable net 3 and fluidic plate 4, and spring 2 is arranged in copper sheathing 1, and movable net 3 passes through spring
2 inside are connected with fluidic plate 4；The right-hand member of copper sheathing 1 sets inside flange, and spring 2 is limited at copper sheathing flange and movable net left end
Between, mesh is uniformly arranged on movable net 3, jet orifice 5 is set in fluidic plate 4, the copper sheathing 1 and movable net 3 are cylindrical shape,
The central axis of the copper sheathing 1, movable net 3 and jet orifice 5 is on the same line.
The mesh is square opening, and the jet orifice 5 is circular port.
With fluidic plate 4 by snapping connection, the copper sheathing 1 and fluidic plate 4 have identical the movable net 3 at contact surface
External diameter.
The effect of spring 2 is to be acted when flow is more than or equal to boundary flow with regard to generation, so the stretch parameter of spring 2 is
Water determines to the thrust of movable net 3 when being more than or equal to boundary flow by flow.Such as Fig. 1, lived when water meter reaches maximum stream flow
Dynamic net 3 is fully open, does not increase crushing；Such as Fig. 2, when flow velocity change is small, activity net 3 retreats, and water projects from jet orifice 5 above,
Activity is so come and gone by movable net 3 and plays a part of range extension.
The utility model is not limited to above-mentioned embodiment, and all are based on technical concept of the present utility model, are made
The improvement in structure gone out, each falls among the scope of protection of the utility model.
