[Industrial applications]

 The present invention is an air / water separator for water pipes, which is inserted in the middle of various water pipes such as cold water pipes for hot air conditioning, hot water pipes, water supply pipes, and hot water supply pipes to discharge the air in the water flowing through the water pipes. Specifically, the water-receiving tank for connecting to the end of the upstream water pipe is connected to the air-water separation tank that floats and separates the air in the water by descending the received water. The present invention relates to a pipe in which an inlet connecting pipe and an outlet connecting pipe for discharging water for connecting to an end of a water pipe on the downstream side are communicatively connected.

[0002]

[Prior art]

 When air is mixed in the water flowing in the water pipe, the air accumulates in the uneven part of the water pipe or the heat exchange part, which causes an air lock that obstructs the flow of water, or the air flows. Noise is generated due to the propagation sound generated at the time and vibration of equipment such as pipes and pumps occurs.

Therefore, an air / water separator is installed in the water pipe. In the conventional water / water separator for water pipe, as shown in FIG. 5, the water pipe C1 on the upstream side is connected to the upper part of the tank 1. An inlet connection pipe 2 for receiving water for connecting to the end is connected in communication, and an outlet connection pipe 3 for discharging water for connecting to the end of the downstream water pipe C2 is connected to the lower part of the tank 1. It was configured to connect and allow the water received in tank 1 to flow down.

[0004]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional technique, the inlet connection pipe is arranged at the upper part of the tank and the outlet connection pipe is arranged at the lower part of the tank. Such an arrangement is also required for the end of the water pipe and the end of the water pipe on the downstream side, and as a result, there will be vertical steps in the layout of the water pipe in the steam separator installation part. , Making the design and construction of water piping equipment difficult.

An object of the present invention is to provide an air / water separator for water pipes in which the ends of the upstream water pipe and the downstream water pipe can be arranged at the same level.

[0006]

[Means for Solving the Problems]

 The feature of the water / water separator for water pipes according to the first aspect of the present invention is that the tank is divided into two parts, an inlet chamber and an outlet chamber, which are horizontally arranged side by side in the tank and communicate with each other at the bottom. A partition is provided, and the inlet connecting pipe is connected to the upper part of the inlet chamber, and the outlet connecting pipe is connected to the upper part of the outlet chamber so as to be positioned at the same or substantially the same level.

The feature of the water / water separator for water pipes according to the second aspect of the present invention is that, in the first aspect, the tank is formed such that the cross-sectional shape of the inner peripheral surface is circular with the vertical axis as the center. In addition, a tank with a side wall is provided, and as a partition, a side wall that horizontally divides the inlet chamber and the outlet chamber is a cylindrical body and is arranged concentrically or substantially concentrically with the tank side wall. The connection pipe is provided so that water in the inlet chamber is supplied tangentially to the inlet chamber so as to impart a turning force about the vertical axis.

A feature of the water / water separator for water piping according to the third aspect of the present invention is that, in the second aspect, a central chamber having a circular cross section surrounded by a partition is formed in the inlet chamber to form a partition. The point is that a chamber having an annular cross-section located between the tank and the tank is formed in the outlet chamber, and the outlet connecting pipe is arranged so as to be located on the extension line of the inlet connecting pipe.

[0009]

[Action]

 According to the first aspect of the invention, by providing the partition in the tank, an inlet chamber communicating with the inlet connecting pipe in the upper portion and an outlet chamber communicating with the outlet connecting pipe in the upper portion and communicating with the inlet chamber in the lower portion are provided. Since it is configured to partition the inside of the tank, water flows from the inlet connecting pipe to the upper part of the inlet chamber, descends and flows in the inlet chamber, flows from the lower part to the lower part of the outlet chamber, and exits via the outlet chamber. Since it is discharged from the connecting pipe, the air in the water is floated and separated during the downward flow in the inlet chamber.

By thus partitioning the inside of the tank into the inlet chamber and the outlet chamber, air separation by downwardly flowing water is performed not in the entire tank but in the inlet chamber, and not in the outlet chamber. Since it also has good performance, it is possible to freely set the installation level of the outlet connection pipe while having the desired air-water separation function. Utilizing this effectively, the outlet connecting pipe is arranged at the same or almost the same level as the inlet connecting pipe, so the upstream water pipe to which the inlet connecting pipe connects and the downstream connecting pipe to which the outlet connecting pipe connects. The water pipe on the side can be placed at the same or almost the same level without a step.

According to the second aspect of the invention, the water in the tank is tangentially introduced from the inlet connection pipe to impart a swirl force about the vertical axis of the water in the tank to the water in the inlet chamber. Since the downward flow can be made into a swirling flow (vortex flow) around the vertical axis, the flow path is made longer and the retention time of water in the inlet chamber, Therefore, the air-water separation time can be lengthened, and thus the air-water separation performance can be made excellent for the distance between the inlet connection pipe and the lower communication port, that is, for the height of the inlet chamber. In other words, the tank can be made small in height and small in size and lightweight in order to obtain the desired water-water separation performance.

According to the third invention, by arranging the outlet connecting pipe in a state of being located on the extension line of the inlet connecting pipe, not only the inlet connecting pipe and the outlet connecting pipe are arranged at the same level, but also those Since the positions for the tank in the left-right direction orthogonal to the axis are the same and are arranged in a straight line, the upstream and downstream water pipes to which these inlet and outlet connecting pipes are connected are at the same level. Moreover, they can be arranged at the same horizontal position. That is, the straight pipe portion of the water pipe can be installed. Moreover, since the inlet chamber to which the inlet connecting pipe is connected is a central chamber surrounded by a partition, the posture in which the inlet connecting pipe is tangentially connected to the inlet chamber so as to generate a swirling flow in the inlet chamber The inlet connection pipe and the outlet connection pipe should be arranged largely offset to the left and right with respect to the tank, in other words, the tank should be arranged largely offset to the left and right with respect to the inlet connection pipe and the outlet connection pipe. This can be prevented, and the overall left-right balance can be improved.

[0013]

[Effect of device]

 Therefore, according to the first aspect of the present invention, which is characterized by what is stated in claim 1, it is easy to design and construct water piping equipment without causing vertical steps in the layout of the water piping in the installation part. It is now possible to provide a steam water separator for water pipes that can be used for manufacturing.

According to the second aspect of the present invention, which is particularly characterized by what is stated in claim 2, not only is the cost reduced by the reduction in size and weight, but the occupied installation space is small and the installation can be advantageously performed in terms of space. Moreover, the installation can be performed with good workability.

Further, according to the third aspect of the present invention, which is characterized by what is stated in claim 3, the positions of the water pipes in the left-right direction can be aligned to further facilitate the design and construction of the water pipe facility. At the same time, handling such as transportation to the site is easy.
