されるようにしている。 A water suction pipe 4 is accommodated in the pressure tank 1, and both ends of the water suction pipe are welded to the side and top surfaces of the pressure tank 1, respectively. The suction side of the pump main body 2 includes a check valve case 5 and a suction side joint pipe 6.
It is connected to the upper end opening of the water suction pipe 4 through a screw, and this connection part is screwed. Furthermore, pump body 2
The discharge side of the pressure tank 1 is connected to the pressure tank 1 via a steam/water separation chamber 7 and a pressure feed pipe 8, and the water in the pressure tank is supplied to an appropriate location through a pipe connected to a piping connection port 9.

出るので、カバー３の効果が半減する。 Note that if noise problems are not taken into account, the water suction pipe 4 does not need to pass through the pressure tank 1. That is, a notch may be provided in the cover 3 and the water suction pipe 4 may be pulled out from this notch. However, with such a configuration, the effect of the cover 3 is halved because noise leaks from the notch.

の防錆処理がしにくい欠点があつた。 Therefore, normally, a water suction pipe 4 is passed through the pressure tank 1 and its both ends are welded to through holes drilled on the top and side surfaces of the pressure tank. However, there was a drawback that it was difficult to perform anti-corrosion treatment inside the pressure tank 1.

ンク内に防錆処理を施すことができるのである。 In this case, a pump body is placed on the upper surface of a pressure tank, and a check valve case is provided on the suction side of the pump body. The first short pipe and the second short pipe are welded, a water suction pipe is inserted through both short pipes, and the upper end thereof is connected to the check valve case, and the flange at the lower end is connected to the first short pipe. The water suction pipe is connected and fixed with a cap nut, and the middle part of the water suction pipe is fixed to the upper surface of the pressure tank via an annular packing by the cap nut screwed onto the second short pipe. This allows the pump to be assembled into a pressure tank without welding during pump assembly. As a result, anti-rust treatment can be applied to the inside of the pressure tank without the presence of water suction pipes.

所に供給される。 The present invention will be explained below with reference to FIGS. 2 and 3. Reference numeral 10 denotes a pump device, in which a pump body 2 is placed on a pressure tank 1 and covered with a cover 3. A through hole is formed in the side surface of the pressure tank 1, and a first short pipe 11 is welded to the through hole formed in the side surface, and a second short pipe 12 is welded to the through hole in the upper surface. ing. Reference numeral 4 denotes a water suction pipe, which is inserted from the first short pipe 11, passes through the pressure tank 1, projects upward from the second short pipe 12, and connects its upper end to the suction side check valve of the pump main body 2. It is connected to the case 5, and the flange 13 at the lower end is in contact with the end of the first short tube 11 via a packing 14. A cylindrical opening 15 is formed on the lower surface of the valve case 5, and the upper end of the water suction pipe 4 is inserted into this cylindrical opening, and a cap nut 16 screwed into the cylindrical opening 15 in advance is screwed. By deepening the mating state, the diameter of the annular packing 17 is reduced, and the annular packing 17 is brought into pressure contact with the water suction pipe 4 to fix and seal the pipe. Further, a piping joint 18 is brought into contact with the lower end of the water suction pipe 4, and a cap nut 19 is screwed onto the first short pipe 11, thereby fixing the piping joint 18 and the water suction pipe 4. Furthermore, a cap nut 20 is screwed onto the second short pipe 12, and by deepening the threaded state of this cap nut, the diameter of the annular packing 21 is reduced, and the annular packing 21 is brought into pressure contact with the water suction pipe 4 to absorb water. It fixes the middle part of the pipe and also seals it. Moreover, the discharge side of the pump main body 2 is
It communicates with the pressure tank 1 through the steam/water separation chamber 7 and the pressure pipe, and the water pressurized by the pump main body 2 and enters the pressure tank 1 through the steam/water separation chamber and the pressure pipe. It is supplied to the appropriate location by a pipe connected to the pipe connection port 9.

ない。 As described above, in the present invention, the water suction pipe 4 is inserted into the pressure tank 1 when assembling the pump device, and the cap nut 19,
20, so when applying rust prevention treatment inside the pressure tank 1, the water suction pipe 4 is not present.
This suction pipe does not interfere with rust prevention treatment.
