Description

Description: TECHNICAL FIELD The present invention relates to a well pump that forms a water channel that penetrates a pressure tank.

[Prior Art] A well pump that forms a water passage through a pressure tank is
If the pressure tank and the water channel are integrally formed by welding or the like, the parts cannot be disassembled. Therefore, the parts are disassembled to be disassembled.

For example, as shown in FIG. 4, a pipe 4 forming a water channel 3 is passed through a through hole 2 of a pressure tank 1, and the pipe 4
An O-ring 5 is provided to connect to the connecting portion 6.

With such a configuration, each component such as the pressure tank 1 can be disassembled, which is convenient.
Since it was necessary to stop the pipe 4 at a predetermined position, the pipe 4 had to be processed.

Such processing is not limited to forming the circumferential groove 7 for holding the O-ring 5 at a predetermined position of the pipe 4 as shown in FIG. Attempts have been made to enlarge the tip of the pipe 4 into a trumpet shape so as not to come off from the tip.

[Problems to be Solved by the Invention] However, the pipe 4 is not easily processed by the conventional method.

That is, when forming a circumferential groove on the outer circumference of the pipe, the pipe must be rotated, and even when the tip of the pipe is formed into a trumpet shape, the pipe must be set in a large machine.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a well pump that forms a water channel having a simple structure and is easy to assemble and disassemble.

[Means for Solving the Problems] The present invention includes a through hole formed in a pressure tank, a pipe that penetrates the through hole, and a hole formed at an end of the pipe to allow a pin to penetrate therethrough. A rigid ring is provided between the pin and the through hole, and O is provided between the ring and the pressure tank.
The problem is solved by interposing a ring and providing a connecting portion for allowing the O-ring to act on the pressure tank and the pipe.

[Operation] The ring of the pipe can hold an O-ring that integrates the pressure tank, the pipe, and the connection part, and this ring is held by a pin fixed to the pipe.

Therefore, the pipe can be easily processed by only the hole penetrating the pin.

[Embodiment] The present invention will be described based on an embodiment shown in the drawings. FIG. 1 is a longitudinal sectional view of an essential part showing an embodiment of a well pump according to the present invention, and FIG. A plan view of the ring and FIG. 3 are plan views of the pin.

In FIG. 1, a well pump has a through hole 9 formed in a pressure tank 8, a pipe 10 is penetrated through the through hole 9, and a hole is formed at a tip portion of the pipe 10 and a pin 11 is penetrated through the well 10. There is.

A ring 12 is attached to the pin 11 on the pressure tank 8 side, and the ring 12 connects the O-ring 13 to the pressure tank 8.
Holds between and.

Furthermore, the O-ring 13 is configured to be pressed by the connection portion 14 against the pressure tank 8 and the pipe 10, respectively, and forms a water channel 15.

The connection portion 14 includes a well pump component such as a pump (not shown), and is configured to be communicated with the water channel 15.

The connecting portion 14 is fastened and fixed to a bolt 16 provided in the pressure tank 8 with a nut 17.

In FIG. 2, the ring 13 is partially notched so that it can be expanded and attached to the pipe 10, and is made of a relatively rigid material.

In FIG. 3, the pin 11 is an ordinary spring pin, and is configured to be driven into a hole formed in the pipe 10 so as not to come off.

In such a configuration, the well pump has a pressure tank 8
The pipe 10 is penetrated through the through hole 9 of FIG.

Then, the pipe 9 is assembled by inserting the pin 11 into the hole, further mounting the ring 12 and the O-ring 13, and fitting the connecting portion 14 therein.

The connecting portion 14 connects the O-ring 13 to the pipe 10 and the pressure tank 8 by screwing the nut 17 onto the bolt 16 and tightening it.
The water channel 15 can be formed by acting to press against the three, fixing the three members integrally and shielding them.

In particular, by providing the pin 10 and the ring 12 on the end side of the pipe 10, the pipe 10 does not enter the inside of the pressure tank 8 from the through hole 9 of the pressure tank 8. Can be assembled.

[Effect of the Invention] According to the present invention, it is possible to easily assemble and disassemble by forming a small hole penetrating the pipe, and the effect as a well pump is extremely large.
