Embodiment
With reference to Fig. 2, the utility model embodiment's hydraulic pressure modulating valve, valve body 1 has water outlet 13 and water inlet 12, the water inlet top of valve body 1 is equipped with voltage stabilizing spool 5, there is cavity 3 housing 51 inside of described voltage stabilizing spool 5, and housing 51 is gone into water cavity 11 and housing cavity 3 seal isolation by its bottom with valve body; The buoyancy aid 52 that can slide along cavity inner wall is arranged in the housing cavity 3, buoyancy aid 52 and on it seal ring 2 of suit be the water cavity 31 on top and the air cavity 32 of bottom with housing cavity 52 seal isolation, described air cavity 32 communicates with atmosphere all the time by the through hole 6 of spool 5 sidewalls; Between described buoyancy aid 52 and the housing bottom Returnning spring 55 is housed, buoyancy aid 52 passes the through hole 53 of housing 51 bottoms and joins with push rod 54, and seal ring 7 is housed between described buoyancy aid and the through-hole wall; Described buoyancy aid 52 is provided with flow channel 4 makes valve body go into water cavity 11 and housing water cavity 31 communicates all the time; Described push rod 54 can seal water inlet when moving to water inlet 12.
The bottom of housing 51 is a gland nut 56 in the present embodiment, described through hole 53 is positioned on the gland nut 56, through hole 53 inwalls are equipped with seal ring 7, make valve body go into water cavity 11 and housing cavity 3 seal isolation, flow channel 4 on the buoyancy aid 52 is gap 42 between water passing groove 43, push rod 54 and the buoyancy aid counterbore of buoyancy aid bottom and the through hole 41 on the buoyancy aid, this flow channel makes valve body go into water cavity 11 and housing water cavity 31 communicates all the time, and current have only the water cavity 31 that just can enter the buoyancy aid top through this passage.
The cavity 3 of housing 51 inside is in gland nut 56 place's diameter maximums, when assembling, can pack buoyancy aid 52 and spring 55 into cavity 3 from lower housing portion integral body like this in.With the technological scheme that present embodiment is equal to mutually be: housing 51 is for dividing body structure, be removably to be connected with gland on the housing, regulating bolt 57 is loaded on this gland, the buoyancy aid 52 of cavity inside and spring 55 etc. are packed into from top to bottom, at this moment, gland nut 56 place's diameters of housing 51 bottoms are unrestricted, even for the ease of making processing, housing and bottom can be overall structure.
In the present embodiment, buoyancy aid 52 is the branch body structure with push rod 54, and push rod 54 1 ends are inserted in the buoyancy aid counterbore and leave the gap and pass through for current.With the technological scheme that it is equal to mutually be: described buoyancy aid 52 is an overall structure with push rod 54, leaves flow channel 4 on the buoyancy aid, makes valve body go into water cavity 11 and housing water cavity 31 and communicates all the time and get final product.
On the push rod 54 shaft shoulder is arranged, the shaft shoulder can seal water inlet when push rod moves to water inlet 12, and push rod also can be tapered etc., as long as they can be with water inlet 12 sealings; Push rod 54 is provided with cushion rubber 8 with water inlet 12 touching positions, can play the effect of damp impacts; Between the water inlet 12 of valve body 1 and the water outlet 13 filtrating equipment is housed, the contaminant filter that enters in the valve body can be come out, and this filtrating equipment is dismantled and assembled, is convenient to timely replacing; Water outlet 13 places at valve body 1 are equipped with check vavle device 9, have prevented that effectively leading interior water from refluxing in valve body 1.
Working principle of the present utility model: current enter valve body from water inlet 12 and go into water cavity 11, install 2 after filtration and enter mixed water valve from water outlet 13, current enter valve body when going into water cavity 11, also can enter the water cavity 31 on buoyancy aid top through buoyancy aid flow channel 4, when hydraulic pressure increases suddenly, the current that enter in the water cavity 31 increase, overcome the active force of spring 55, promote buoyancy aid 52 to lower slider, push rod 54 moves downward thereupon, thereby the distance between push rod 54 and the water inlet 12 is shortened, reduce the water flow that enters in the valve body; Otherwise when hydraulic pressure reduced suddenly, the current that enter in the water cavity 31 reduced, and under the effect of Returnning spring 55, buoyancy aid 52 upwards slides, and push rod 54 is washed open by current, has increased the water flow that enters in the valve body.So just realized making the water yield that finally enters in the mixing valve keep balance, thereby playing the purpose of stablizing the mixing water temperature along with water pressure fluctuations is regulated the water flow that enters in the valve body automatically.
In order further to control the water flow of water inlet 12, there is sealing that the move up and down adjusting bolt 57 of scope of one may command buoyancy aid 52 is installed at housing 51 tops, regulate between bolt 57 and the buoyancy aid 52 spring 58 is housed, by regulating this bolt, can give spring 58 certain pretightening force, and can control buoyancy aid 52 and rise at utmost, with the maximum flow of water amount of restricted passage water inlet 12.
Voltage stabilizing spool of the present utility model is owing to have buoyancy aid 52 in the housing, thereby can float with variation in water pressure and regulate the inflow at water inlet 12 places, realize that balance enters the effect that mixes the hydraulic pressure in the water valve, structure is ingenious, realize reliably can being widely used in various mixed water valves, thermostatic valve etc.
Mode of execution of the present utility model is not limited to the above embodiments; can also there be other to change, but so long as realizes function of the present utility model or reach effect of the present utility model all should belonging to protection domain of the present utility model in the mode that is equal to replacement with essentially identical means.
