The intelligent control valve for open-loop sealing water pump provided by the model utility is used to control opening and closing the valve, to enable the valve to open and close slowly without restrictions of any working condition, with good effect of waterproof hammer, small flow resistance and simple structure.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of trip ring water-sealed pump intelligent control valve.
Background technique
In present self-powering type multifunctional water force control valve, generally all adopt epithelium formula or piston type sealing control cylinder with big, little two valve plates cooperate the quick closing valve of realizing valve, slowly close, with pass valve water hammer and the check function after the realization elimination termination of pumping, the big valve plate of this class valve can slide up and down on valve rod, and be suspended in the valve body, determine its residing position by valve interior fluid pressure, little valve plate generally is connected with control cylinder by valve rod, controlled cylinder drives, control cylinder generally is separated into the control chamber epicoele and the control chamber cavity of resorption of positive confinement by rubbery membrana dermalis or piston and O type rubber seal, control chamber epicoele and control chamber cavity of resorption respectively with the advancing of valve, go out to connect.There is the problem of following aspect in this class valve: one, the big valve plate of Xuan Fuing occupies certain flow channel space and produces resistance, and the weight of big valve plate relies on hydrodynamic pressure to hold up fully and forms resistance, there is the big valve plate of suspension under fluid impact, to produce fast rotational again, causes the valve shake and form pressure surge; Two, in these control valve for water pump structures, cylinder and piston (diaphragm) must seal, the switching resistance that is produced by seal friction is big, engaging pressure needs 0.08MPa, and epithelium formula control chamber since diaphragm roll over repeatedly scratch occur aging, higher temperature and pressure is easier to make that diaphragm is aging to be torn, thereby control mechanism was lost efficacy, piston and O type rubber seal are because the gap of piston and cylinder is little, unholiness medium is easy to occur " card cylinder " phenomenon and O type rubber seal move repeatedly easily aging, wearing and tearing, causes control mechanism to lose efficacy; Three, large and small valve plate cooperates and goes up complicatedly, and the sealing level is many, poor reliability, and adopt large and small valve plate secondary to close valve, the water hammer peak value often, and big (peak-peak is not less than 1.53 to 1.6 times of pump working pressure) influence life-span of facility use.
The model utility content
Technical problem to be solved in the utility model provides a kind of valve slow open and close and is not subjected to any operating mode restriction, the anti-trip ring water-sealed pump intelligent control valve that water hammer is effective, flow resistance is little, simple in structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of trip ring water-sealed pump intelligent control valve, comprise valve body, piston cylinder, piston, valve rod, control chamber epicoele and control chamber cavity of resorption, described valve rod end is provided with the valve plate corresponding with described valve body, pipe fitting one end that modulating valve is housed is communicated with described control chamber epicoele, and the other end is communicated with described control chamber cavity of resorption.
The seal ring that is equipped with on the described piston is the opening seal ring.
Adopt the trip ring water-sealed pump intelligent control valve of technique scheme, the opening seal ring of adorning on the piston utilizes its tension force that the side is contacted with piston cylinder, end face contacts with piston under pressure, the opening seal ring can be regulated automatically during operation, make piston cylinder form two control chambers up and down of relative sealing, utilize flow of fluid pressure to make control chamber epicoele liquid transfer to the control chamber cavity of resorption by pipe fitting when opening pump, valve plate is slowly opened; After the termination of pumping, pressure of return water is transferred to the control chamber epicoele with control chamber cavity of resorption liquid by pipe fitting in the pipeline, and valve plate is slowly closed non-return, by transfer liquid repeatedly in upper and lower control chamber, realized slow open and close, by adjusting control valve opening, may command slow open and close time.
The utlity model has following advantage:
1, adopt and once to close valve, fixing valve plate can pressure surge during equipment operation, and it is little to cross flow resistance;
2, the automatic adjusting function of opening seal ring can solve appearance " card cylinder " phenomenon and seal ring move repeatedly easily aging, wearing and tearing, the problem that causes control mechanism to lose efficacy, and make valve make difficulty of processing to reduce greatly;
3, because upper and lower control chamber must positive confinement, reduced control mechanism surface friction drag, made the engaging pressure of valve reduce to 0.01Mpa by 0.08Mpa;
4, anti-water hammer is effective, and peak-peak can be reduced to 1.2 to 1.3 times by 1.53 to the 1.6 times of pump working pressure that are not less than of conventional valve.
Comprehensively described, trip ring water-sealed pump intelligent control valve provided by the utility model is used for the keying control of valve, makes that the valve slow open and close is not subjected to any operating mode restriction, anti-water hammer is effective, flow resistance is little, simple in structure.
