Heating System

Published by:

In the maintenance of the heating system includes: repair of leaks in pipes, appliances, fixtures, replacement of individual sections of heaters, faucets, insulation of pipes and equipment that are in open or cool places, expansion tanks, removal of pipeline reverse slope, installation of additional fixtures, and strengthening the existing hangers and hooks, setting taps in places where you can not solve reverse slope or air pockets (bags); Troubleshooting site management and boiler, inspection and replacement of faulty instrumentation, washing, cleaning and painting of expansion tanks, Sump, elevators, stop and control valves, air collectors, flushing of the system (annually at the end of heating season) and its regulation. When major repairs shift pipelines, replace or repair furnaces, water heaters, pumps, control units, boilers. Receiving repaired the system in operation beginning with the inspection and verification of compliance with its technical documentation on the repairs.

Before the test, open all valves and taps on the air collector. For connecting a hydraulic press and fill it with water through the back line.

Filling produce slowly so the air is completely removed from the system. Once in the valves of the air tanks will be water, close them and create pressure in the hydraulic press system in excess of 1.25 times the working. After 5 min. pressure drop should not exceed 0.02 MPa. After testing and commissioning of a selection committee make preservation of the system before the heating season. For this system is filled with purified water from the thermal network. Regulate the heating system at the beginning of the heating season as follows. Open the valve on the input to the heating system of the building and serves coolant from the thermal network pipes and heaters.

Then pass along the main pipelines, check the heating of the lower points of all risers. On the overheated riser cover taps, gradually attaining the same temperature Return water in all risers. Then seek uniform heating radiators on the floors, covering the taps of overheated equipment. The temperature is determined in the middle section of the radiator, farthest from the riser. The thermal test is considered complete if the room temperature deviates from the estimated no more than 1 2 C.

Solenoid Valves

Published by:

Every year the interest in the solenoid valves is growing rapidly, as evidenced by statistical data. The main reason for this growth is the automation of the technologies, the need to reduce dimensions and mass indexes of complete installations. As well as increasing requirements of environmental regulations and quick-input mixer. The simplicity of design, installation and reliability allows you to apply solenoid valves in virtually all industries. For all the variety of names: solenoid valves, solenoid valves, solenoid valves, solenoid valve, solenoid, , etc., has one functionality and tighter. They are installed in pipelines and open or override the flow of the working environment (depending on what type of valve it is – normally open or normally closed). The functioning of these valves occurs when the signal from the control systems or additional sensors installed in direct contact with the solenoid. Solenoid valves are used in the apcs and energy technologies, nuclear industry, engineering, oil & gas and petrochemical industries, in heating systems, water supply and water supply, gas supply, etc. Solenoid valve – this is the most affordable solution for automating the management of flows of liquids and gases.
