1. Overview of TJ40H Manual Control Valve
The manual regulating valves and self-selling manual regulating valves produced by our factory are mainly used in urban centralized heating, circulating water engineering, thermal power plant pipe network and refrigeration and air conditioning projects
It has the functions of cutting off, throttling and regulating flow and can replaceOrifice plate, is a variable apertureThrottling device, cut-off temperature: ≤425℃.
Main parts materials
Parts materials: valve body, valve cover, packing gland, valve stem, valve disc, sealing ring, indicator, valve stem nut, nut sleeve
Materials: Gray cast iron, cast steel, stainless steel, stainless steel, brass
2. T40H manual regulating valve
T40H manual regulating valve is composed of valve body, valve seat, valve disc, valve stem, valve cover and other parts. It is installed on oil, water and other pipelines, and the size of the window area formed by the valve disc and the valve seat is changed by rotating the cylindrical valve disc, so as to achieve the purpose of regulating flow. The opening and closing angle of the regulating valve is 60., which is indicated by the opening indicator plate installed above the regulating valve. Medium temperature: 0~170℃.
Performance characteristics
1. Improve heating supply: All branches and heating points using manual regulating valves can adjust the flow rate according to the designed working conditions to achieve good temperature conditions. This type of regulating valve has better regulating performance than gate valves and stop valves, and it has a nearly linear regulating performance. Therefore, the uneven heating and cooling of each heating building has been effectively improved.
2. Energy saving: Due to the imbalance of temperature and pressure in the heat pipe network, some branches have too much flow, making some buildings too hot, and users have to open windows to save energy.
3. Improve the hydraulic working condition of the network management: The manual regulating valve can be controlled according to the rated flow, reduce the flow of the network management in excess, and improve the original water working condition to a certain extent.
