Directly buried type full welded ball valve compared with ordinary valve normal need to connect the valve and pipe flange, screw, gaskets, valve and pipe connection spend a large amount of material resources, is not conducive to the global environment and energy conservation and emissions reduction.And straight type full welded ball valve without flange, bolts, gaskets, in the form of welding and pipes.Good sealing, easy to operate.
Directly buried type of full welded ball valve in the heating pipe network systems development background
1, the heating network is often buried in the underground in order to control the valve to be tall valve well, rain or snow will put the rubbish into the valve well, these waste, can produce a large number of harmful gas in the borehole.Operators of the control valve valve well cause personnel injury.Valves and pipes burst will cause harm to the operators.
2, heating pipelines due to reasons such as construction, welding, corrosion pipeline often have sundry, medium flow will carry these sundry flush valve seal structure, the valve sealing surface damage valve closes lax, shut off the valve becomes ornament.
3, the common need to connect the valve and pipe flange, screw, gaskets, valve and pipe connection spend a large amount of material resources, is not conducive to the global environment and energy conservation and emissions reduction.For the directly buried type full welded ball valve to obtain the very good development.
Directly buried type of full welded ball valve USES:
City gas: gas output pipeline, trunk and the regional supply, etc.
Central heating: large heating equipment output pipeline, trunk and feeder.
Heat exchangers, piping and the opening and closing of each circuit.
Steel mills: all kinds of fluid pipes, exhaust pipes, gas and heat supply pipeline, the fuel supply line.
All kinds of industrial equipment: all kinds of pipes, all kinds of industrial gas and heat pipe heat treatment.
Advantage of directly buried type of full welded ball valve:
1, straight type full welded ball valve can be directly buried in the ground, to build tall valve well, in order to reduce the project cost, at the same time also can avoid the operation of the valve cause harm to the staff.
2, directly buried fully welded ball valve is opened, the valve ball seat completely surrounded, despite impurities not scour seat and medium sphere seal face, because of this special structure to make valve closure and pipes with the same life.
3, closed buried type welded ball valve medium static damage on the sphere and the sealing seat, open the sphere and the process of the stationary medium deposited debris scrape, under seat spring compensation change of pressure and temperature compensation function, ensure that won't produce any leaks.
4, directly buried fully welded ball valve can be directly welded to save the flange, screw, gaskets, save a lot of material resources.
