The dn40 thermomix valve
Product use
The thermostat valves are a complementary product developed by my company for thermal water system and are widely used in electric water heaters, solar water heaters and centralized water heating systems. It can also be applied to electric water heaters and solar water heaters, where users can adjust their own temperature for cold and hot water, as required, which can be achieved and stabilized quickly, and the temperature of the water is constant, free from changes in water temperature, flow and water pressure, and the temperature and heat of the bath centre can be addressed. When cold water is interrupted, the mixed water valve can automatically shut down the hot water for a few seconds to protect it。
Rationale
At the mixing point of the heating water valve, there is a heat-sensitive element that uses the properties of the temperature original to drive the core of the valve to move, seal or open cold, hot water entry. When cold water is blocked and hot water is activated, the temperature adjusts the temperature of the spin button, the temperature of the cold and hot water entering the vent changes, regardless of temperature or pressure, so that the temperature of the flow remains constant, and the temperature of the heat button can be set at any time within the specified temperature of the product, and the temperature of the temperature mix will be automatically maintained。
Main technical parameters
Work pressure: 0. 05-. 05mpa
Optimal work pressure: 0. 1-0. 5 mpa
Cold water temperature: 5-29 degrees hot water temperature: 50-95 degrees
Higher hot water temperature: <95 degrees temperature range: 35-45 degrees
Temperature-controlled accuracy: ±2 degrees of vent flow: 8 tonnes/h (water supply pressure 0. 1 mpa)
Path: dn 40 (inner screw connection)
Small traffic: 0. 8 tonnes/hw: 1. 7kg
Installation and attention
1. The red mark is hot water. The blue mark is cold water。
2. After setting the temperature, when the temperature or pressure of the water supply changes, the output temperature varies by 2 degrees。
3. If cold and hot water pressure is not consistent, a one-way stop valve should be added to the intake to prevent cold and hot water interlocking。
4. If the cold, hot water pressure ratio is greater than the pressure, the pressure reduction valve shall be fitted on the side of the pressure to allow normal regulation of the mixed water valve。
5. When selecting and installing, note that the requirements of a generic pressure, water mixing temperature range, etc. Are consistent with the product parameters。
Use and debug notes
1. Debug temperature shall be applied to larger discharges。
2. Control buttons are in the direction of cooling, reverses are in the direction of heating, and initial reconciliations are to be noted in the direction of cooling to high temperature in order to prevent burns。
3. If cold, hot water input pressures are inconsistent, install one-way stop-valves to prevent cold and hot water interlocking。
