Embodiment
Set forth the utility model further below in conjunction with Figure of description, and provide embodiment of the present utility model.
This hydraulic control flow balance valve of relying on oneself, comprise main valve and diaphragm type balance Auxiliary valves, main valve wherein comprises main valve body 1, spool 4, upper valve rod 12, main valve lid 11, valve seat 3; Diaphragm type balance Auxiliary valves comprises diaphragm 9, outer valve gap 8 and one group of adjusting needle valve 7 and one group of adjustment ball valve 5; Main valve body 1 lumen segmentation is become valve body input cavity A and valve body output cavity B by main valve lid 11 and the spool 4 that is connected with upper valve rod 12 by main valve wherein, the center hole of main valve lid 11 is stretched out in the upper end of described upper valve rod 12 and diaphragm 9 is fixed, and forms through being spirally connected with outer valve gap 8, main valve body 1 the hydrodynamic valve pocket that diaphragm type balances Auxiliary valves.
The bottom of described spool 4 is provided with the lower valve rod 13 that is furnished with locking framework, main valve body 1 is directly stretched out in the lower end of described lower valve rod 13, described locking framework is made up of the sliding sleeve 14 be nested with in lower valve rod 13 body of rod underpart and the nut 15 be positioned at below sliding sleeve, and described locking framework forms overall structure through a bottom be connected with main valve body 1 16 with main valve body.
In actual applications, nut is screwed into the underpart of lower valve rod 13 for 15 times by this hydraulic control flow balance valve of relying on oneself when normal use, allow sliding sleeve 14 free fall, ensure that spool 4 freely can move up and down on the valve seat 3 of main valve body 1 inner chamber, adapt to the needs entering the different flow of valve body input cavity A inner fluid.Diaphragm 9 is changed once needs, as long as open the bottom 16 of main valve body 1 bottom, the nut 15 be arranged on lower valve rod 13 is upwards twisted, promote sliding sleeve 14 moves until make lower valve rod 13 and main valve body 1 lock, the spool 4 be now connected with lower valve rod 13 upper end will close the flow channels between main valve body input cavity A and valve body output cavity B.As long as now open the outer valve gap 8 on main valve body 1 top, take off the diaphragm 9 being arranged on upper valve rod 12 upper end portion, just can realize the replacing to diaphragm.Both whole valve can have been made after reverse operating to enter normal operation.So in the process of whole replacing rubber flap, both need not cut off the fluid passage of fluid upstream input end, also need not pull down whole valve.
The outer valve gap 8 of described diaphragm type balance Auxiliary valves arranges symmetrically two groups of self-powering types to surge self-balancing mechanism, this self-powering type self-balancing mechanism that surges comprises a pair adjusting needle valve 7 and a pair and regulates ball valve 5, and it is directly through and through the equilibrium structure of surging regulating pipeline and adjustment ball valve 5 to form and the valve body input cavity A of main valve body 1 and valve body output cavity B is through respectively that each adjusting needle valve 7 described and diaphragm type balances the hydrodynamic valve pocket of Auxiliary valves.
Adopt this symmetry shape to be arranged on two groups of left and right self-powering types of outer valve gap 8 to surge self-balancing mechanism, make this kind rely on oneself hydraulic control flow balance valve in working order time, along with fluid enters valve body input cavity A, under the effect of pressure being transferred fluid, spool 4 rises the passage opened between valve body input cavity A and valve body output cavity B, now, the diaphragm 9 be on upper valve rod 12 also rises thereupon; The fluid simultaneously entering valve body input cavity A also can constantly be arranged on by being connected with it on the left of outer valve gap 8 by regulating pipeline 6, regulate ball valve 5, adjusting needle valve 7 enters diaphragm type and balances in Auxiliary valves, and excess fluid part entered in diaphragm type balance Auxiliary valves from the adjusting needle valve 7 be arranged on the right side of outer valve gap 8, regulate ball valve 5 and regulate pipeline 6 to be connected with the valve body output cavity B of main valve body 1, formed and the auxiliary flow of through each other outer valve gap 8 in main valve body 1.Once the transfusion runner stopping infusion operation of main valve body 1, in valve body output cavity B liquid self fluid pressure effect under, make spool 4 press down passage between closed valve input cavity A and valve body output cavity B, make the operation of whole main valve stopping infusion.Reset is moved down now along with diaphragm 9, make the flowing medium in valve body output cavity B by being arranged on adjustment pipeline 6 on the right side of main valve body 1, regulate ball valve 5, adjusting needle valve 7 enters outer valve gap 8 and fill up because diaphragm moves down the space of appearance, make diaphragm type balance the valve pocket of Auxiliary valves and main valve body inner chamber is in same interior pressure condition.
In addition, the self-powering type adopted in the technical program surges self-balancing mechanism, what the left side was wherein arranged be communicated with the admission chamber A of main valve body 1 a set of by regulating pipeline 6, regulate ball valve 5, adjusting needle valve 7 enters diaphragm type and balances in Auxiliary valves, be communicated with in the bottom of described adjustment ball valve 5 in the pipeline of the valve body input cavity A of main valve body 1 and set up a safety check 2 in addition, in order to prevent fluid backflow when stopping fluid conveying.
