Water to warm service water heating system as a covert project
- HVAC projects include ventilation and air conditioning works and heating works.s
To warm the system main material and auxiliary materials which include what
- 1, to warm the main material parts are: wall-hung boilers, heating the main channel, sub-catchment, to warm pipe, such as temperature control. Large houses are also equipped with heating circulating water pump (from the pressurized effect), constant temperature mixing valve (energy saving and good comfort) and so on. These devices are the main part of the warm floor, but also to warm the main supplies, especially the boiler and to warm the tube, the basic occupation of the vast majority of the warmth of the ridge to bogey Yao Xu surprised only super-fee; Some are: reflective film, extruded board (insulation board), steel wire mesh, the border insulation strips, to warm the staples, insulation casing, raw materials, such as ball valve. The price of these auxiliary materials is not high, more varieties, the market is complex, but these accessories are warm to install the important details of the heating system to the energy-saving effect and insulation effect is to warm the auxiliary materials are inseparable.s
Casing head test pressure process
- Test pressure 1. Test pressure single test pressure and system test pressure, single test pressure: after the completion of the trunk pipe or hidden parts of the pipeline installation is completed according to the design and specification requirements for water pressure test. System test pressure: heating system installed according to the design and specification requirements for system water pressure test. 2. Heating, air conditioning system test procedures: a first check the entire system of all control valves are open, the system should be separated from the outer pipe network, open the gas tank release valve. B will be the water main pipe, test pressure pump and other temporary pressure test pipe connected to the main water supply pipe, and irrigation to the system, to be filled with water system and cutting ingot Cui melon Chaozhao sleep bile duct system After the discharge of the air, the release of the valve out of the water so far), close the release valve; c operation test pump to boost, boost the process should pay attention to check management, fittings and accessories are leaked, such as seepage Leakage should stop the pressure to suppress, and after the buck to repair, change pad, tighten and so on. D system without leakage, the pressure and boost to the test pressure, stop the pump check, and observe the pressure gauge, requiring 10 minutes pressure drop of not more than 0.02Mpa, that is qualified.s

Steam heating system,affecting the two parts of the radiator heating effect?
- Heating the two steam sources should be the pressure difference is not (all low-pressure steam, not suitable for more than 0.4MPa steam direct heating), the proposed use of unit hydrophobic, trap two hydrophobic pipe can be connected together. Even if the same heat source, in order to ensure the use of the effect of helium power Jiabo Huang Feng Wei Fu fruit, do not recommend multiple groups of radiators share a trap.s
