Embodiment
Further specify technical characteristics of the present utility model below in conjunction with accompanying drawing.
A kind of better embodiment of the present utility model as depicted in figs. 1 and 2, double-deck automatic voltage regulation current stabilizer comprises valve body 1, first movable sheath 3, first spring 4, second movable sheath 6, second spring 7, adjutage 9 and seal ring 10 from top to bottom successively;
First movable sheath 3 is the pipe of top seal, and its tube wall top has 4 lead channel 5, and lead channel is the hollow slots of vertical direction; The outside, first movable sheath, 3 lower ends has annular flange flange 18;
Second movable sheath 6 is the pipe of top seal, and its tube wall top has 4 lead channel 8, and lead channel is that the width of vertical direction is the hollow slots of 2mm;
Have belt flange 25 on the inwall of adjutage 9, its outer wall bottom has belt flange 11, has outside thread on the outer wall of flange 11, the bottom 16 sheathed seal rings 10 of flange 11, and the outside, lower end of adjutage 9 has annular flange flange 22;
The external diameter of adjutage 9 upper ends is slightly less than the internal diameter of second movable sheath 6; The external diameter of second movable sheath 6 is slightly less than the internal diameter of first movable sheath 3.First movable sheath 3 is placed in this valve body 1 inside, and its top is resisted against the lower edge of the annular flange flange 24 of valve body 1; First spring 4 is placed in this first movable sheath, 3 inside, and its upper end is resisted against the inside top of first movable sheath 3, and its lower end is resisted against second movable sheath, 6 top outer; Second movable sheath 6 is placed in this first movable sheath, 3 inside; Adjutage 9 is placed in this second movable sheath, 6 inside; Second spring 7 is placed in this second movable sheath 6 and this adjutage 9 inside, and its upper end is resisted against the inside top of first movable sheath 3, and its lower end is resisted against inwall flange 25 upper limbs of this adjutage 9;
The outside thread 11 of adjutage 9 is threaded mutually with the internal thread 21 of valve body 1 inwall bottom.
The working principle of this bilayer automatic voltage regulation current stabilizer is, during no pressure, because of the elastic force of first spring 4, first movable sheath, 3 tops are resisted against the lower edge of the annular flange flange 24 of valve body 1.When liquid is flowed through liquid entering hole 2 when entering valve body 1, the pressure of liquid stream promotes first movable sheath 3 and moves to the liquid flow path direction, 24 of annular flange flange at first movable sheath, 3 tops and valve body 1 produce the space, liquid passes through, and entering the inlet 15 of adjutage 9 via lead channel 5 and lead channel 8, the liquid outlet 14 by adjutage 9 flows out the voltage stabilization and current stabilization valves again.
When hydraulic pressure increased, first spring 4 further was squeezed, gap turn narrow, and first movable sheath 3 inwardly contracts, and poor 5 latus rectums of feed liquor diminish; Correspondingly, second spring 7 also further is squeezed, gap turn narrow, and second movable sheath 6 inwardly contracts, and poor 8 latus rectums of feed liquor diminish, and cause flow quantity to diminish.
When hydraulic pressure reduced, first spring, 4 gap enlargement promoted first movable sheath 3 and protract, and poor 5 latus rectums of water inlet become big, and correspondingly, second spring, 7 gaps also become greatly, and second movable sheath 6 protracts, and poor 8 latus rectums of feed liquor become big, caused flow quantity to become big.
Adjust the front and back position of adjutage, fine-tuning spring pressure, control flow rate conformity.This device is under 0.0-0.5kg pressure, and the regime flow error can guarantee various traffic demand products in the 1-3% scope, and corollary equipment uses.
