Description

  The present invention relates to a vacuum valve unit used in a vacuum sewer system, and more particularly to a vacuum valve unit suitable for installation in a residential area where installation space is limited.

  In recent years, as a sewer system for collecting wastewater from a house, a vacuum sewer system for collecting by vacuum suction has been developed and used instead of a conventional natural flow sewer system. As shown in FIG. 1, this vacuum sewer system has a residential drainage system composed of a natural flow pipe 101 installed in the basement of the residential area, a residential land mass 107, a vacuum valve unit 102, and a residential area. And a vacuum station 104 provided on the downstream side of the vacuum pipe 103, and a vacuum station 104 installed in the underground of a public land such as a public road. In this vacuum sewer system, the sewage discharged from the house flows into the sewage basin 105 of the vacuum valve unit 102 through the natural flow down pipe 101 and is temporarily stored therein. When a predetermined amount or more of sewage Q in the sewage basin 105 accumulates, the sewage Q is opened by the vacuum suction force applied to the vacuum pipe 103 connected to the vacuum valve 106 by opening the vacuum valve 106 of the vacuum valve unit 102. Is collected in the vacuum station 104 through the vacuum line 103.

By the way, in the above-described vacuum sewer system, the vacuum valve unit 102 installed in the residential land includes, for example, a sewage water 105, a vacuum valve 106 connected to the vacuum pipe 103, and one end of the sewage water as shown in Patent Document 1. The vacuum valve 106 is composed of a suction pipe 107 which is arranged in the first 105 and connected to the vacuum valve 106 at the other end, a controller (not shown) for controlling the opening and closing of the vacuum valve 106, a sensor (not shown) for detecting the water level in the sewage water, and the like. These components are housed and arranged in one sewage can 105 as a unit. Here, the sewage basin 105 is made of concrete or made of resin such as FRP, and these are properly used depending on the conditions of the installation location. When this vacuum valve unit 102 is installed in a residential land owned by a private company or in a bottleneck, etc., one using a small resin wastewater tank 105 is selected, and as shown in FIG. It was replaced with one of the residential land 107 connected to the ground and buried in the residential land or in the basement of Kushiro.
