Rubber-cord compensatory branch pipe-valves serve to decrease the level of vibration and noise, to shutoff pipelines, and also to provide for compensation of assembly, temperature and working displacements of pipelines being connected. Their main feature is simplicity of design, reliability and durability in operation; they can be used in water-supply and sewer plants, and also for shutoff of strongly polluted and aggressive environments in chemical, mining, metallurgical and a pulp and paper industry.
These branch pipes have no rubbing and wearing details, are not subject to corrosion and sediment on surfaces contacting with a liquid. The design of branch pipe-valves completely excludes leaks of a transferred liquid which take place, for example, at wearing-out of ordinary valves.
The development of compensating branch pipe-valve patented.
Rubber-cord nozzles are hollow tubular shells reinforced with high-strength nylon cord and have a 3-fold margin of safety for destructive pressure. The angle of the reinforcing strands of the cord is chosen such that when applying pressure, the branch pipes-valves are spaceless, i.e. they do not exert a force on the connected pipelines. Lengths of elastic elements of branch valves (size L,) correspond to lengths of standard valves and therefore branch pipes can be installed instead of valves, including for the period of their repair. At the request of the customer the required modifications of branch pipes-latches, both on the geometrical sizes, and on properties of rubber can be issued. By special order, valve nozzles can be produced, working with a medium whose temperature exceeds 100 °C.
