Described weighing apparatus pressure control valve, valve pocket 30 is arranged on valve inner, is tightly connected with described water inlet valve body 10, valve pocket 30 offers water hole 1.
Described weighing apparatus pressure control valve, valve plug 40 hollow, and there is an opening, this opening is downwards just to described water inlet 11.Valve plug 40 sidewall offers water hole 2 41.Valve plug 40 is mounted slidably in valve pocket 30 so that only can be connected with outlet 21 by the water inlet 11 of described valve body by the water hole 1 offered on the water hole 2 41 offered on the opening of valve plug, valve plug and valve pocket, valve plug 40 has spring auxiliary section.
Described weighing apparatus pressure control valve, spring 50 is arranged in valve pocket 30, is positioned at above valve plug 40, and spring one end supports valve pocket 30 upper end, and the other end coordinates with the spring auxiliary section of valve plug 40.
Described weighing apparatus pressure control valve, weighing apparatus pressure control valve also includes sealing ring 1, sealing ring 2 82, is arranged on between water valve body 10 and water outlet valve body 20, and between valve pocket 30 and water inlet valve body 10.
Described weighing apparatus pressure control valve, when intake pressure reduces, the active force of valve plug 40 is reduced by hydraulic pressure, and valve plug 40 is rebounded downwards by spring 50 so that the water hole 2 41 of valve plug 40 increases with the lap of the water hole 1 of valve pocket 30, and discharge change is little；When intake pressure increases, the active force of valve plug 40 is increased by hydraulic pressure, and spring 50 is compressed, and the water hole between valve plug 40 and valve pocket 30 reduces, and discharge change is little, thus reaching the function of weighing apparatus pressure.
For achieving the above object, weighing apparatus pressure control valve provided by the invention, including valve body, valve pocket, valve plug and spring, it is characterized in that: valve body hollow, valve body offers water inlet and outlet, valve pocket offers water hole, valve plug hollow, and there is an opening, valve plug sidewall offers water hole, valve pocket is arranged in valve body, valve plug is mounted slidably in valve pocket, making only can by the opening of valve plug, the water inlet of described valve body is connected by the water hole offered on the water hole offered on valve plug and valve pocket with outlet, valve plug has spring auxiliary section, spring is arranged in valve pocket, one end of spring coordinates with the spring auxiliary section of valve plug.
As it has been described above, the present invention utilizes valve plug to coordinate with spring, during the intake pressure change that valve plug bears, valve plug slides in valve pocket, dynamically regulates the size of water hole, so that the discharge by the pressure control valve that weighs is stable, reaches weighing apparatus compression functions.The present invention can be widely used in the cold water incoming end of bath apparatus, has simple in construction, advantage easy to assembly.
