に戻される。As the collected and removed contaminants remain on the upstream side of the filter, the pressure loss of the flowing water passing through the filter increases, and the pressure on the downstream side of the filter decreases. Then, as the filter continues to collect and remove contaminants, the pressure value on the downstream side of the filter detected by the pressure gauge, or the value of the pressure difference between the upstream side and the downstream side of the filter, is set in advance. When a predetermined value, that is, a value resulting from contaminant retention within an acceptable limit, is reached, the control device is actuated to close both gate valves and open the bypass valve and the discharge valve. state. Then, flowing water is passed through the filter from the downstream side of the filter in a normal state through the bypass pipe, and the stagnant contaminants are discharged together with the flowing water to the outside of the water distribution pipe through the discharge pipe. Then, after a certain period of time, the control device returns to the normal state.

b is provided. And this pair of gate valves 2a,
A collection pipe 4, which has a filter 3 capable of removing contaminants and is capable of iTJ, is formed with a diameter larger than that of the pipe 1, and forms a part of the water distribution pipe. The filter 3 is made of stainless steel and has about 100 meshes. The collection pipe 4 has a gate valve 2 at the upper part of both ends thereof.
It is connected to the pipe 1 via a and 2b, and a discharge pipe 5 is opened and connected to the lower part of the upstream end of the collection pipe 1. The discharge pipe 5 is provided with an electromagnetic discharge valve 6 interposed therebetween and communicates with a sewage gutter (not shown). The bypass pipe 7 has one end opened to the collection pipe 4 between the filter 3 and the downstream gate valve 2b, and the other end opened to the piping 1 further upstream from the upstream gate valve 2a. An electromagnetic bypass valve 8 is interposed in the middle of the bypass pipe 7. Furthermore, a pair of pressure gauges 9a and 9b capable of detecting the pressure inside the pipe are provided on the upstream and downstream sides of the collection pipe 4 with the filter 3 as a boundary. and,
Each gate valve 2a, 2b, discharge valve 6, bypass valve 8, and each pressure gauge 9a, 9b are electrically connected to a control device 10. The control device 10 controls the pressure value downstream of the filter 3 detected by the downstream pressure gauge 9b, or the pressure value of the upstream and downstream sides of the filter 3 detected by the upstream and downstream surface pressure gauges 9a and 9b. Based on the difference value of pressure value.
各仕切弁２ａ、２ｂと排出弁６とバイパス弁８とを開閉

Contaminants flowing through the pipe 1 together with the flowing water A are filtered through the filter 3.
is collected and removed by As the collected and removed contaminants remain on the first stream side of the filter 3, the filter 3 becomes clogged, and the pressure loss of the flowing water A passing through the filter 3 increases, and the pressure on the downstream side of the filter 3 increases. descend.

The value of the difference between the pressure values on the upstream side and the downstream side of the filter 3 detected by the filter 3 reaches a predetermined value preset in the control device IO, that is, a value resulting from contaminants staying within the permissible limit. When this happens, the control device 10 operates,
Both gate valves 2a and 2b are closed, and the bypass valve 8 and discharge valve 6 are opened.

In addition, this allows the removal efficiency of the filter 3 to be kept constant at all times. 6 In addition, in this embodiment, the explanation has been made assuming that the water always flows in one direction in the pipe 1, but the direction of flow can be changed. If it changes depending on the time,
As shown in FIG. 3, there is a branch pipe 1a in the middle of the plumber's work.
