Valve body it is inside and outside, be easy to fluid to circulate.The extension of the connecting hole includes big footpath section and path section, big footpath section and path section
Transition position is provided with step, and the adapter is set in path section and terminates in the step.
Through hole stretch section with adapter welding position, connecting hole extension with adapter welding position, through hole stretch section with
The welding position of connecting hole extension is located at the step, and after above-mentioned three's welding, weld-ring is formed at the step.More
Body, the weld-ring are located at main valve body round cavity and the intersection of adapter, i.e. weld-ring be located at the connecting hole extension and
The intersection of the main valve body round cavity.
The main valve seat is combined by planar section and the welding of pipe section lease making, and the connecting hole is arranged on the pipe fitting
Part, main valve seat are welded with main valve body by pipe fitting part (being specially the extension of connecting hole), are different from prior art and pass through
Main valve seat and main valve body madial wall bump contact and the connected mode of welding.
The outer surface annular knurl of adapter, adapter and the stretch section of through hole are fitted close, and then welded seal.
The utility model is not in the case where changing each parts function, performance, by the knot for changing main valve body, main valve seat
Structure, improve main valve seat and main valve body, the main valve body and disconnected bad problem of weldering of adapter welding, simultaneously as main valve seat is connected through
The extension in hole is welded with main valve body through hole, and therefore, main valve seat material requested is reduced, and reduces four-way valve manufacturing cost.
