Integral waterproof type building heat supply computerized control unit

Abstract

The invention relates to an integral waterproof type building heat supply computerized control unit comprising a prefabricated chamber (1) and self-operated flow control valves (2). The integral waterproof type building heat supply computerized control unit is characterized in that orifices (18) sleeved with sealing devices (14) are formed on two sides of the prefabricated chamber (1), a water pipe A (15) and a water pipe B (16) run through the prefabricated chamber (1) through the orifices (18), an antitheft device (10) is arranged on the upper portion of the prefabricated chamber (1), a sealing ring (11) is arranged on the inner wall of the antitheft device (10), the two water pipes are communicated with each other through a bypass valve (7), and a cable hole (12) for outgoing of power supply and instrument cables is formed in the upper portion of the prefabricated chamber (1). With the integral waterproof type building heat supply computerized control unit, water permeation and mixing caused by extension and contraction of the pipes is overcome effectively; rainwater permeation and the like can be avoided effectively due to special processing of a wellhead and a well cover; all discharged water during running and maintenance in heat supply can be drained out of the chamber directly so as to keep the chamber dry.

Description

technical field [0001] The invention relates to the technical field of building heating, in particular to a metered and controlled heating unit in front of a building. Background technique [0002] At present, most or all of the entrance devices in front of the thermal building are installed in the well chamber, and almost all of the thermal well chambers are seriously polluted due to waterproof problems, forming perennial water accumulation, and even soaking heating facilities such as pipes and valves in sewage. The corrosion of heating facilities is exacerbated, and the service life is greatly reduced. Although water is pumped many times a year, it is not long and full of sewage. This phenomenon is very common in various heating companies. [0003] In recent years, the country has vigorously promoted heat metering technology and installed heat meters in the heating system.

Problems solved by technology

[0002] At present, most or all of the entrance devices in front of the thermal building are installed in the well chamber, and almost all of the thermal well chambers are seriously polluted due to waterproof problems, forming perennial water accumulation, and even soaking heating facilities such as pipes and valves in sewage. Exacerbating the corrosion of heating facilities, the service life is greatly reduced. Although water pumping is organized many times a year, the time is not long and the sewage is full. This phenomenon is very common in various heating companies

[0003] In recent years, the country has vigorously promoted heat metering technology, and installed heat meters in the heating system. Many heat meters are installed in thermal wells. Because the heat meter head integrator is an electronic component, in such a harsh environment It is difficult to adapt to the environment. Although in the bidding and procurement of heat meters, the protection level of heat meters is required to meet the waterproof requirements of IP68, but from the actual situation, there are few heat meters in China that can meet this requirement.

The thermal well chamber is humid and hot during the heating period. After the heat is stopped, the temperature of the well chamber drops a lot. When the heat meter encounters cold, heat, or steam, the seal of the heat meter calculator is difficult to work, resulting in heat meter failure.

Although the heat meters are repaired, they have been repeatedly repaired and broken. In particular, most of the heat meters in front of the building are large-caliber heat meters. The price is high, tens of thousands, and the investment is huge.

Even cause many contradictions between heating companies and users,
