Description
Technical field
The present invention relates to valve technology field, for fluid delivery system, be specifically related to a kind of self-powering type manual multifunctional mortar flow control valve.
Background technique
Direct-operated regulator relies on and flows through the pressure of medium self in valve, temperature as driven by energy valve automatic operation, does not need ABAP Adapter and secondary meter.Also known as self force type control valve.Direct-operated regulator all utilizes the feedback signal of valve output terminal (pressure, pressure reduction, temperature) to be delivered to actuator by signal tube and drives flap to change the aperture of valve, reach the object regulating pressure, flow, temperature.Self-contained pressure regulator, because it is without the need to external energy, working without the place of electricity without gas, both conveniently can again save the energy.Pressure segmentation limit is thin and cross one another, and degree of regulation is high.Actuator survey precision high, be active in one's movements.Adopt pressure balance mechanism, modulating valve is quick on the draw, controls accurate advantage, and be widely used in mortar conveying, heating installation and supply wet goods field.
CN 102829221 A discloses a kind of self-powering type steady flow control valve, comprise valve body, valve gap, enter bellmouth and go out bellmouth, orifice sleeve is provided with in valve body, be tightly connected in orifice sleeve pressure-regulating sleeve and flap, formed in cavity and be provided with valve rod between pressure-regulating sleeve and flap, and on valve rod, cover has disc spring, valve gap is stretched out in the upper end of valve rod, the lower end of valve rod is flexibly connected with flap, and valve rod is provided with jump ring, and the lower end surface of jump ring contacts with the upper surface of pressure-regulating sleeve; Be arranged with groove at the excircle of orifice sleeve, the upper end of groove communicates with the cavity above pressure-regulating sleeve jointly, the lower end of groove with enter bellmouth and communicate, be respectively equipped with the restriction of circumference uniform distribution in the lower end of orifice sleeve; Be provided with the valve seat of hollow in the bottom of valve body, the hollow portion of valve seat with go out bellmouth and communicate, valve seat and flap fasten.This pressure regulator valve has from pressure adjusting function, namely when upstream pressure has fluctuation, can automatically regulate restriction aperture, thus guaranteed flow is stablized to a certain extent.
Although above-mentioned patent has from pressure adjusting function, but Problems existing can not regulate pressure size on a large scale, and especially the structure of valve body adopts curvilinerar figure, liquid needs upwards to back down flap from the bottommost of curvilinerar figure import and then arrives another export pipeline, this structure is used in the field of neat liquid as oils, heating supplies etc. can realize, if be used in mortar transportation art, due to curved valve body, mortar because of self gravity when the import by bottom enters in bottom by retentate portion mortar, cause follow-up mortar cannot enter valve body smoothly, often mortar is trapped in the bottom of valve body, and the water of mixing will wash flap arrival export pipeline open, this modulating valve is caused to lose efficacy.
CN201434091 discloses direct-operated regulator, comprises spool and valve seat; It is characterized in that: described spool is ball shape structure, coordinating between spool with valve seat is linear contact lay.
Although above-mentioned patent solves the problem that mortar is detained, the regulation range of this modulating valve is less, and therefore application is restricted, and pressure regulates inconvenient.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, provide a kind of rational in infrastructure, easy to adjust, pressure regulation spectrum is large, and application is extensive, and there is not the self-powering type manual multifunctional mortar flow control valve of mortar retention problems.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of self-powering type manual multifunctional mortar flow control valve, comprise and can be responsible for described mortar the mortar overflow chamber resettling with spill pipe be connected, being provided with between mortar supervisor and mortar overflow chamber resettling allows overvoltage mortar to be responsible for the overflow hole flowing into mortar overflow chamber resettling through mortar, the pressure adjusting lever for opening and closing overflow hole protruding upward mortar overflow chamber resettling is provided with in described mortar overflow chamber resettling, the opening/closing mechanism with described overflow hole adaptation is provided with in the bottom of pressure adjusting lever, top is provided with the rotating handles that pilot pressure adjustable lever moves down, length direction along described pressure adjusting lever is disposed with at least two groups for regulating the controller perturbation mechanism with two guide rods of pressure adjusting lever impacting force.
