Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1 to FIG. 4: a kind of vertical spiral shell wing watchcase of anti-reverse, packet
Watermeter shell 1 is included, the watermeter shell 1 is the cylindrical tube shape structure of upper and lower opening, and horizontal symmetrical is opened on the side wall of watermeter shell 1
Equipped with water inlet 2 and water outlet 4, water inlet 2 and water outlet 4 are arranged close to the lower part of watermeter shell 1, and the outside of water inlet 2 connects
It is connected to water inlet pipe 3, water outlet 4 is externally connected to outlet pipe 5, and water inlet pipe 3 and outlet pipe 5 are collinearly arranged, outside the water meter
The lower end internal engagement of shell 1 is inserted with partition box 6, and the outer diameter of partition box 6 is equal with the internal diameter of watermeter shell 1, partition box 6 it is upper
End opening lower end closed, horizontal symmetrical is offered into water connector 7 and water outlet connector 8 on the side wall of partition box 6, when partition box
When in 6 insertion watermeter shells 1, water inlet connector 7 is connected with water inlet 2, and water outlet connector 8 is connected with water outlet 4, partition
The inside of box 6 is equipped with partition 9, and partition 9 is vertically arranged, and the perpendicular where partition 9 is connected with water inlet connector 7 and water outlet
Perpendicular where mouthfuls 8 is in 45 ° of settings, when water flow enters in watermeter shell 1, water flow can first pass through into water connector 7 into
Entering in partition box 6, the plane where the direction of water flow and partition 9 is in 45 ° of settings, therefore when water flow is entered in partition box 6,
Water flow can reversely change, simultaneously as partition 9 will intake, the beeline channel between connector 7 and water outlet connector 8 separates, because
This water flow can not only change in the horizontal plane flow direction, can also change flow direction upwards, and the top of the watermeter shell 1 is equipped with lid
Plate 10, the lower end center of cover board 10 are fixed with mounting base 11, and the lower end center of mounting base 11 is equipped with cylindrical briquettes 12, circle
The lower end of cylindricality briquetting 12 is coaxially installed with impeller shaft 13, and the side of impeller shaft 13 is uniformly equipped with impeller 14, cover board 10
Lower end be also equipped with baffle 15, baffle 15 and cover board 10 are perpendicular, and the length of baffle 15 is equal with the internal diameter of watermeter shell 1,
And when cover board 10 is installed, baffle 15 is coplanar with partition 9, and such structure setting makes shape between partition 9 and baffle 15
At a water stream channel, and impeller 14 is mounted in this water stream channel, therefore when water flow enters in watermeter shell 1, water
The flowing of stream becomes impeller rotation again, and the normal reading of water meter, and because plane of the partition 9 where with baffle 15 are realized with this
Flow direction with water flow is in 45 ° of settings, so water meter also may be implemented just even if reversely installing between water inlet pipe 3 and outlet pipe 5
It is often used.
Further, the lower end of the impeller shaft 13 is equipped with inserted block 16, and the upper end center of partition 9 offers slot 17, when
When cover board 10 and partition box 6 are installed in watermeter shell 1, inserted block 16, which is inserted into setting, such setting in slot 17, to be made
It is more stable to obtain impeller shaft 13, will not be rotated because of prolonged impeller 14, and impeller shaft 13 is loosened.
Further, upper connecting flange 18, upper connecting flange 18 and cover board are equipped at the upper end port of the watermeter shell 1
10 edge cooperates, and lower connecting flange 19 is equipped at the lower end port of watermeter shell 1, is equipped with outside the lower end of partition box 6
Partition box connecting flange 20, lower connecting flange 19 cooperate with partition box connecting flange 20.
Further, the end of the water inlet pipe 3 is equipped with water inlet pipe connecting flange 21, and the end of outlet pipe 5 is equipped with water outlet
Pipe connecting flange 22 facilitates water inlet pipe 3 and the installation of outlet pipe 5 to connect.
Working principle: in use, cover board 10 and partition box 6 are installed, partition 9 and the meeting of baffle 15 will be outside water meters at this time
The inner space of shell 1 is divided into uniform two parts, and the unique passage between two parts only between partition 9 and baffle 15 connects
It is logical, and impeller 14 is also equipped with by impeller shaft 13 in this channel, therefore when water flow passes through 1 inside of watermeter shell, be bound to
Can be by the channel between partition 9 and baffle 15, and impeller 14 rotates, in this way can so that water meter display reading, and
Because plane and water (flow) direction where partition 9 and baffle 15 be in 45 ° of settings, the direction of water flow no matter pros can be real
The normal rotation of existing impeller 14, does not mind that the normal use of water meter may be implemented in the positive and negative installation of water meter.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
