Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 to Fig. 4 shows an embodiment of the utility model combined type water meter housing, comprises the watchcase 1 of bringing the mouth of a river 11 and a water delivering orifice 12 into.One side of its water delivering orifice is provided with a valve pocket 13, is provided with the ball valve 2 of the vertical valve rod 4 of ribbon gymnastics in this valve pocket, and this ball valve can rotate in this valve pocket, makes flexible operation.The outer end of this valve pocket connects a titting water outlet 7, in order to water outlet; As shown in Figure 1.
One sphere centring ring 10 is set between this water inlet 11 and the described ball valve 2.One sphere centring ring 9 and O-ring seal 6 is set between this ball valve 2 and the pipe adapter 7.In order to the tram of ball valve in this valve pocket, location, and in order to excellent sealing between ball valve and the pipe adapter; As shown in Figure 1.
13 ones of watchcase valve pockets are provided with a valve-rod cavity, and this valve-rod cavity and described manipulation valve rod 4 are set to be rotatably assorted, and make flexible operation.
Be provided with valve stem packing ring 5 and step pad 3 between described manipulation valve rod 4 and the described valve-rod cavity; As shown in Figure 3; To keep reaching good sealing effectiveness and less driving torque.
The characteristics of the utility model combined type water meter housing combine water meter case and valve by integrated design.
Its course of work is: be installed in that tap water enters from watchcase water inlet 11 in the pipeline, rotate by handling valve rod 4, drive ball valve 2 and rotate, come the water in the controlling plumbing fixtures to flow out from the water delivering orifice 12 of watchcase; Fig. 1 is depicted as ball valve water flowing state; Fig. 2 is depicted as the ball valve state of cutting off the water supply.
According to the characteristics of water meter design specification and valve, the utility model watchcase of combined water meter has following structure and characteristic of property:
1, water meter sealing property height. Improve the water meter sealing, in the constant situation of other conditions, reduce sealing surface Number is best selection, and water meter housing and valve casing unite two into one to design and reduced the sealing surface number, and compact conformation, and be outer Shape is attractive in appearance, reaches " seamless " and connects.
2, it is little to flow through the pressure loss of water meter. The pressure loss refers under the certain flow state, flows into hydraulic pressure and the stream of water meter Go out hydraulic pressure poor of water meter; This energy loss is the smaller the better. In the constant situation of other conditions, adopt ball valve 2, ginseng See shown in Figure 1ly, in the design of all valve mechanisms, its pressure loss minimum because under the water flowing state, allows pipeline In the straight-through valve that flows through of water, without any turning or bundle strength phenomenon produces resistance.
3, the durability of valve is good. Durability refers under certain flow water flowing condition, makes the switch motion each what of valve After inferior, valve is in closed condition, and when the source pressure certain value, leakage rate is the smaller the better. By test of many times, valve Door leaks when main because the wearing and tearing of when rotation increase and cause, and this wearing and tearing also are difficult to overcome, in order to reduce leakage, The utility model adopts highly elastic material sealing ring 6, since reduce the displacement of it and ball valve, thereby reach the purpose of sealing.
4, the valve rotating torque is little. Under the water flowing state, the switch of valve is made up of to drive motor and one group of reducing gear Ovable valve stem rotates, and General Requirements moment is littler, and the main cause that causes the valve rotary resistance to increase be positioning seal ring, Centring ring is relevant with the frictional force between the ball valve, this frictional force again with they between thrust relevant; The 2nd, at hydraulic pressure Effect lower valve rod step plane and the housing step plane between produce friction, above-mentioned these two groups of friction all produce moment of torsion; In order to reduce their friction, adopt high-elastic gonosome material seal circle 6, and centring ring adopts the very little material of coefficient of friction. To the friction of valve rod and the generation of housing step plane, the centre increases a pad that coefficient of friction is very little. Through the reality test, After taking above-mentioned measure, frictional force can reduce more than 50%, thereby reaches the little purpose of rotating torque.
The utility model can extensively can be used in the water meter of valve control, such as IC-card water meter, Long-distance Control water meter etc. respectively Plant in the prepay water meter.
