the upper cavity and the lower cavity are further communicated through the liquid outlet channel, and the buffer space of the fluid after decompression is increased, so that the balance and stability of the pressure of the fluid output from the liquid outlet are further improved while the pressure is reduced.
By adopting the hand-adjusting pressure-stabilizing valve, fluid entering from a liquid inlet at a certain pressure sequentially flows through a liquid inlet channel and a lower cavity and then is output outwards from a liquid outlet at a smaller pressure, the balance and stability of the pressure of the output fluid can be improved, the length of an adjusting bin can be adjusted through rotating a guide seat, the elastic piece is adjusted in an extrusion state, and finally the elastic adjustment of the tension of the spring is realized, so that the pressure of the fluid at the liquid outlet after pressure reduction and pressure stabilization is adjusted, the requirements of the fluid pressure adjustment and the consistency and stability of the fluid pressure at the liquid outlet are further met, the concentricity between an adjusting block and a push rod can be self-adaptively adjusted in the adjusting process, the uniformity and stability of acting force at each place are ensured, and the balance and stability of the pressure of the fluid at the liquid outlet are further improved;
further, through the switching between the pipe body portion of ball head portion and connecting nozzle on the end cap, to flowing through feed liquor passageway, lower cavity back with less pressure outwards from the liquid outlet in proper order with the fluid that certain pressure got into from the feed liquor mouth, and can improve the equilibrium and the stability of output fluid pressure, through the floating setting to the end cap again, can realize the coaxial regulation of self-adaptation between end cap and the feed liquor passageway of reciprocating flexible removal, avoid the atress disturbance because of the end cap eccentric lead to, both can improve the life of subassembly, can further guarantee equilibrium and the stability to fluid pressure regulation again, and the annular channel of end cap upper ball head and surrounding the ball head portion offer, then can further carry out the pressure equalizing and the pressure-relief to the fluid that flows through, thereby improve the equilibrium and the stability of fluid pressure in liquid outlet department.
