DN100x80 National Standard Reducing Rubber Flexible Joint for ‘High-Rise Direct Connection to Heating Units’

DN100x80 National Standard Reducing Rubber Flexible Joint for ‘High-Rise Direct Connection to Heating Units’

The official website of Shanghai Songjiang Vibration Absorber Group Limited introduces: DN100x80 National Standard Reducing Rubber Flexible Joint for ‘High-Rise Direct Connection to Heating Units.’ Songjiang Group provides high-temperature-resistant national standard reducing rubber flexible joint products tailored for high-rise direct connection to heating units, offering excellent vibration reduction and noise reduction effects.

Flange Material: Carbon Steel or QT450

Rubber Material for Heating Units: EPDM Rubber (up to 120 degrees Celsius).

Production Technology: Our factory is certified by TUV Rheinland in Germany, and our products have been inspected and approved by the Shanghai Municipal Quality and Technical Supervision Bureau. We have our own research and development team, design department, and production facility. Each rubber joint product is engraved with our factory name (to ensure we can provide after-sales service for customers even after several years), rather than just attaching a label. This is because we have over 500 sets of our own molds, making us incomparable to small manufacturers.

Introduction to Direct Connection Heating Units: High-rise direct connection heating equipment is composed of components such as a variable frequency control system, isolator, circulation pump, cyclone dirt separator, piping, instruments, and a self-control system.

Functions of High and Low Zone Direct Connection Heating Units:

1. Programmable and equipped with remote communication interfaces, allowing for local network control.
2. The system has power outage protection and an automatic water source isolation function, as well as an automatic delayed start function when power is restored.
3. High-rise direct connection heating equipment automatically controls pressure based on pressure signals.
4. Based on pressure signals, the system automatically adjusts the frequency of circulation pumps and can achieve automatic switching between multiple circulation pumps without manual intervention.
5. It achieves full automatic control of the entire high and low zone direct connection heating unit without the need for personnel on duty.
6. The direct connection control panel can provide DCS remote signal interfaces, receiving DCS output signals for “equipment start command” and “equipment stop command,” as well as switch control signals.

Scope of Application:

1. Heating systems that require zoning in high-rise buildings (new construction).
2. Heating systems that require zoning in high-rise buildings (renovation).
3. Central air conditioning water systems that require zoning in high-rise buildings.
4. Heating systems in multi-story buildings located at the end of the heat network, where the return water pressure difference is too small to guarantee normal flow.
5. Multi-story buildings in the same heat network with significant differences in elevation.

System Components: High-rise building heating direct connection equipment mainly consists of water pumps, check valves, butterfly valves, rubber joints, remote pressure gauges, pressure gauges, pressure reducing valve assemblies, electric contact pressure gauges, control panels, solenoid valves, flow switches, dirt separators, and thermometers.
