Overflow weir (overflow trough) made of PVC

Overflow weir (overflow trough) made of PVC

It is a weir for evenly discharging the supernatant water that has been separated by sedimentation in sedimentation tanks (sedimentation chambers) and the like. It is also referred to as an overflow trough. In many cases, a continuous triangular notch (V-notch) is used at the top of the weir. Everything from dimensions, channel width, to outlet size can be manufactured according to your preferences. It is also possible to manufacture only V-notch plates and movable weirs. Brackets and supports can also be provided.

Water Supply and Drainage Product Catalog

A lineup of products for water supply and drainage, including cast iron movable weirs, gate opening and closing devices, and flap valves!

This catalog introduces the water supply and drainage products handled by Saito Iron Works. With a rational and simple structure, the wedge is designed to be adjustable, making it easy to adjust in case of repairs, such as the "cast iron sluice gate," and the "cast iron movable weir," which was developed from years of manufacturing experience for the purpose of flow measurement and water level adjustment. In addition, we also introduce products such as the "telescope valve," "gate opening and closing device," and "flap valve." Please use this for selecting products. [Contents] ■ Cast iron sluice gate ■ Cast iron movable weir ■ Telescope valve ■ Gate opening and closing device ■ Flap valve *For more details, please refer to the PDF document or feel free to contact us.

[Construction Case] Certain Housing Complex - Trench and Center Well Replacement Work

This is a case study of the replacement work of an aging iron overflow weir with a new resin one.

We would like to introduce a case of replacing an aging iron overflow weir in a certain housing complex with a new resin one. The existing overflow weir at the site was at risk of falling due to deterioration, necessitating prompt restoration. After a site survey, we manufactured an overflow weir of the same size using PVC and carried out replacement work, including surrounding equipment. 【Construction Case】 ■ Manufacturing Days: 14 days ■ Type of Work: Equipment Installation ■ Work Days: 2 days ■ Date/Location: June 2019/Shiga Prefecture ■ Equipment Used: Trench, Center Well *For more details, please refer to the PDF document or feel free to contact us.

Shape of Weirs That Are Less Prone to Turbulence | Important Runner Design in Casting

Explaining the essential conditions for installing a weir! Introducing the cross-sectional shape of the flume (weir) and more!

The installation of weirs and riser pipes is directly linked to product quality, so careful consideration of the installation location and diameter is necessary. Additionally, we often see unnecessary riser pipes added due to concerns about casting failures. Increasing the number of riser pipes beyond what is necessary can lead to turbulence, which has a negative effect. In this column, we will explain the essential conditions for installing weirs. We encourage you to read it. 【Contents】 ■ What is a weir ■ Essential conditions for riser pipes ■ Cross-sectional shape of riser pipes (weirs) ■ Diameter of riser pipes and flow rate ■ Changes in flow rate due to differences in weir shape *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.

Yue Liu Weir (Shen Dian Trench)

Since it is made of FRP (fiberglass reinforced plastic), it has excellent corrosion resistance, chemical resistance, and solvent resistance.

In a channel shaped like a trough, the supernatant water from the sedimentation tank overflows through a V-notch. It has a high tensile elongation rate and is resistant to impact.

River gate rubber dam

The cost performance of the rubber gate is pleasing.

It is a rubber gate used for water storage in rivers. In places where gradual water level adjustment is not required, low-cost and low-failure rubber gates are adopted. Air is pumped into the rubber bag body to form a dam. When the air is released, it becomes a flat collapsed shape. By cutting the tip at an angle, it allows for smoother water flow, preventing damage from debris such as gravel and boulders, and reducing vibrations caused by turbulence.

Basics of Installing a Weir | Important Runner Design in Casting

Introducing the basics of dam installation and methods to prevent "cracks" that can occur at the junction between the dam and the product!

The definitions of the runner and the gate vary somewhat depending on methods such as sand casting, lost-wax ceramic shell method, and block molding method. The term "runner" originally refers to the path through which molten metal reaches the product part of the mold, encompassing the entire wax tree except for the pouring basin. In this column, the term "gate" specifically defines the junction between the runner and the product within the runner. We encourage you to read on. [Contents] ■ Basics of gate installation ■ Appropriate thickness of the gate ■ Methods to prevent "cracking" at the junction of the gate and product ■ Proper installation position of the gate ■ Dividing the runner into multiple parts ■ Runner sprue *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.
