Abstract

PURPOSE:To make a microscopic flow rate detectable without resting on an expensive flow detector, by installing a flow switch being closed by approximation of the magnet installed in a valve body, in the case of a device which installs a flow detecting device detecting the quantity of water to be discharged out of a hydrant. CONSTITUTION:When a pump is driven, a check valve chest 22 in a pump body 21 comes to negative pressure, whereby water is sucked in via a clearance A between a peripheral wall of a valve body 27 and a bush 25, and this valve body 27 is displaced upward. This displacement takes place relatively speedier till a fluid passing window 32 is exposed, but after exposure of this window 32, it comes gentle, and a step part 49 of a valve stem 28 comes into contact with a guide cylinder 44 whereby this displacement of the valve body 27 is stopped. At this time, at a displacement position of the valve body, where it comes to the specified low flow rate, a magnet 35 comes nearer to a reed switch 38 and turns on the said switch 38 whereby a fact that it is the low flow rate is detected, and with the detected output, for example, the pump is stopped, and feed water is controlled so as to done from a pressure vessel.

In the pump device configured in this way, when the pump is driven, the check valve chamber 22 becomes negative pressure, water is sucked through the gap A between the peripheral wall of the valve body 27 and the bushing 25, and the valve body 27 is pressed against the bushing. 30, the upward displacement begins. Here, the flow rate Q flowing from the gap A and the displacement dimension X of the valve body 27
As shown in FIG. 10, the valve body 27 is displaced to X4 due to the flow rate Q4 until the fluid passage window 32 of the valve body 27 is exposed from above the bushing 25, and then the fluid passage window 32 is exposed. 32 is exposed from the bushing 25, the cross-sectional area of the flow path increases, so the displacement dimension with respect to the flow rate becomes small. For example, for a flow rate change of Qs Q<, the displacement dimension becomes Xs Xa. When the displacement dimension X is reached, the stepped portion 49 of the valve shaft 28 comes into contact with the guide cylinder 44 as shown in FIG.
The displacement dimension of the valve body 27 is regulated. Thereafter, as shown in FIG. 10, the position of the valve body 27 remains constant regardless of the increase in the flow rate Q. Note that a valve body 27 is provided at the lower end of the guide cylinder 44.
The stepped portion 49 of the valve shaft 28 comes into contact with the valve body 27 rather than directly, and wear of the valve body 27 is reliably prevented.

By the way, when the flow rate exceeds Q2, the displacement dimension of the valve body 27 becomes X2, the magnet 35 approaches the reed switch 38,
The reed switch 38 is turned on, and the ON signal is outputted to the outside via the cord 50. That is, the low flow rate Q2 is detected by closing the reed switch 38. In this case, the variation in flow rate detection accuracy is caused by the fact that even if the flow rate increases slightly from Q2 to Q3, the valve body 27 will displace greatly from X2 to X and reliably close the reed switch 38. can be kept within an extremely small range.

Also, when the flow rate decreases from Q to Q4, the valve body 27
The displacement is from X to X4, and then the fluid passage window 3
2 becomes lower than the upper end of the bush 25, the valve body 27 is rapidly displaced from X4 to X due to a slight change in flow rate from Q4 to Ql, and the reed switch 38 is opened in the range of X3 and X2.

Here, when the valve body 27 is lowered, since the ring 48 is integrated with the lower part of the support column 47, this ring 48
is displaced using the bushing 25 as a guide, and the valve body 27 is prevented from riding on the bushing 25 when descending. In this case, a part of the bushing 25 is attached to the inner flange 2.
3, sand and the like accumulated on the flange end face 23b are prevented from entering between the packing 30 and the bushing 25.

On the other hand, the cord 50 is connected to the brush 1 land 51 of the printed circuit board assembly 40, and the connection wire 38a of the reed switch 38 is connected to both second lands 52, and the reed switch 38 is positioned below the printed circuit board 39. Therefore, by arranging the reed switch 38 and the printed circuit board 39 inside the recess 37a and the recess 54,
It is attached to the printed circuit board assembly 40 with one touch, and the upper part thereof is sealed with a gasket 42, and the vibration of the printed circuit board assembly 40 is suppressed.

Furthermore, since the cord 50 is guided below the inclined surface 56, even if water droplets should adhere to the cord 50 during use, the water droplets will be prevented from entering the vicinity of the printed circuit board 39. That is, the printed circuit board 39 is placed in the recess 55, the reed switch 38 is placed in the recess 37a, and an inclined surface 56 is formed that is continuous with the bottom surface 57 of the recess 37a and guides the cord 50 downward. It is. Moreover, even if moisture intrudes due to an unexpected accident, since the bottom surface 57 of the recess 37a and the inclined surface 56 are continuous, the infiltrated moisture will be immediately discharged to the outside from the inclined surface 56, and the reed switch, edge 38, etc. It is possible to prevent the occurrence of electrical leakage accidents.

Incidentally, the water may contain gold dust, iron powder, etc.
Since the valve stem 28 and the guide tube 44 are both made of brass and non-magnetic, it is possible to prevent gold dust, iron powder, etc. from adhering to these two members 28° 44, and the guide tube 44 and the valve stem 28
A smooth relative displacement between the reed switch 38 and the reed switch 38 is reliably maintained over a long period of time, and malfunctions of the reed switch 38 caused by adhesion of gold dust, iron powder, etc. are also prevented.

As explained above, according to the present invention, there is provided a cylindrical pump body that has a valve seat on its peripheral wall and opens above the valve seat, and a cylindrical pump body that is provided inside the pump body so as to be movable up and down and that are seated in the upper and lower parts. A cylindrical valve body with a bottom and a fluid passage window is provided, and a flow rate switch is provided above the valve body and connected to a flow rate detector. Since a magnet that opens and closes is attached to the valve body side, when the magnet approaches, the flow rate switch closes and a minute flow rate can be detected. Therefore, since a conventionally required flow rate detector is not required in the piping system, deterioration of the pump characteristics including the piping can be prevented. Further, since the flow rate detector is not attached to the water supply pipe, there is no need to install a float or the like in the pipe as in the conventional case, and the pump system can be simplified.
