Description
Technical field
The utility model relates to a kind of flow dontroller, what be specifically related to is the anti-blocking alkaline-resisting high pressure type flow dontroller that is used to contain the flow control of alkali lye body.
Background technique
Flow dontroller be widely used in as a kind of instrument product industries such as chemical industry, oil, metallurgy, electric power automatic flow control system in.Flow dontroller generally is made up of flowmeter, Digital Controller, electric actuator, modulating valve.To the adjusting operating mode of highly pressurised liquid, adopt multistage mazy type modulating valve or multistage aperture formula sleeve adjusting valve to come repeatedly step-down and throttling on the engineering mostly to be fit to high-pressure liquid.But all there are shortcomings such as runner is complicated, flow resistance is big, the runner dead angle is many in two kinds of modulating valve; Particularly in high pressure alkali lye operating mode; The characteristics that have severe corrosive and easy crystallization because of alkali lye; Alkali lye crystalline polamer in trim corrosion and the runner will appear in flow dontroller in short service time, can't cause the flow dontroller cisco unity malfunction by the normal flow admittance to such an extent as to stop up medium until runner at last.Because the internals of traditional modulating valve generally adopt precipitation hardening of martensitic stainless steel to make, be prone to quickened crystallization after the corrosion again by alkali liquid corrosion again, obstruction has been quickened in crystallization, forms vicious circle.
Summary of the invention
The purpose of the utility model is for solving the above-mentioned defective that existing flow dontroller exists, the anti-blocking alkaline-resisting high pressure type flow dontroller of a kind of anti-plugging, alkaline-resisting corrosion being provided.
Realize above-mentioned purpose; The utility model adopts following technological scheme: a kind of anti-blocking alkaline-resisting high pressure type flow dontroller, comprise flowmeter, valve body, valve seat, spool, inner valve sleeve, outer valve sleeve, electric actuator, digital governer, and wherein inner valve sleeve is set in the outer valve sleeve; It is characterized in that: the described inner valve sleeve upper edge axial position at least two group throttle orifices that have been spaced apart; Every group of throttle orifice is provided with two holes at least, and wherein every group of throttle orifice cooperates formation step-down control with spool, and the outer circumferential face of this group throttle orifice is close to the inwall of outer valve sleeve; Described outer valve sleeve is provided with one group of through hole; This group through hole is provided with two through holes at least, and the hole away from one group of throttle orifice of valve seat on through hole and the inner valve sleeve is superimposed, and superimposed back connects with the outlet of valve body.
Through adopting such scheme; The beneficial effect of the utility model is: because the side working principle of inner valve sleeve and outer valve sleeve: single tube page or leaf and two-tube page or leaf produce relative rotation when opening the door; Plunger rod and plunger are that a rotor rotates simultaneously, and plunger is also done straight reciprocating motion along the straight-tooth of plunger rod lower end, and this motion is to be the relative movement between another rotor by nut sleeve; Making plunger do axis while rotating moves; Plunger moves up when opening the door, one-way valve opens when moving on the plunger, and the hydraulic oil on oil cylinder top flows into the oil cylinder bottom through one-way valve; Its transmission at closing time is identical when opening the door, and just plunger moves from top to bottom, this moment closed check valve, the hydraulic oil of oil cylinder bottom flows to the top of oil cylinder through series flow control valve, can regulate the speed of closing the door this moment.Many groups throttle orifice of some quantity is set on the wall; This particular structure and valve seat, spool have been formed the throttling design of multistage step-down, have avoided tortuous many curved aperture runner designs, have eliminated the runner dead angle; Make the complete machine negotiability increase, anti-plugging effect preferably and high pressure resistant poor is arranged.
The further setting of the utility model is: described every group of throttle orifice is provided with four holes, and described every group of through hole is provided with four through holes, and described spool, inner valve sleeve and outer valve sleeve adopt the nickel-bass alloy material of high tenacity and high hardness to make.
The effect of the technological scheme that further is provided with is: adopt the nickel-bass alloy material of high tenacity and high hardness to make spool, inner valve sleeve, outer valve sleeve; Because nickel-base alloy has physical propertys such as strong corrosion resistant property, high tenacity and high hardness; Guarantee the not only alkaline-resisting corrosion of flow dontroller, and erosion that can high pressure resistant fluid.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of Fig. 1 inner sleeve;
Fig. 3 is the structural representation of Fig. 1 outer sleeve.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of anti-blocking alkaline-resisting high pressure type flow dontroller comprises flowmeter 1, valve body 2, valve seat 3, spool 4, inner valve sleeve 5, outer valve sleeve 6, valve gap 7, electric actuator 8, Digital Controller 9.Wherein inner valve sleeve 5 is set in the outer valve sleeve 6, in the utility model embodiment, and the described inner valve sleeve 5 upper edge axial positions two groups of throttle orifices 51,52 that have been spaced apart; Can set many group throttle orifices according to actual needs; Every group of throttle orifice is provided with four holes 511,521, can certainly set a plurality of holes according to actual needs, and wherein every group of throttle orifice 51,52 cooperates formation step-down control with spool 4; And the inwall of being close to outer valve sleeve 6 on the outer circumferential face of this group throttle orifice 52; Described outer valve sleeve 6 is provided with one group of through hole 61, and this through hole is provided with four logical 611 holes, can certainly set according to actual needs; Four holes 511 away from one group of throttle orifice 51 of valve seat 3 on four through holes 611 and the inner valve sleeve 5 are superimposed, and superimposed back connects with the outlet 21 of valve body 2.
In normal operation, there is the setting flow value that presets Digital Controller 9 inside.When instrument runner medium flows through; The actual flow of flowmeter 1 collection medium; Digital Controller 9 is delivered in the flux signal change of reality, and compared, when actual flow is less than normal or bigger than normal with Digital Controller 9 inner setting flow values; Digital Controller 9 will be controlled aperture that electric actuator 8 drives spools 4 and become big or diminish, and is consistent with the setting flow value up to final adjusting actual flow.
Implement in the profit at the utility model; Two groups of throttle orifices 51,52 are set on the inner valve sleeve 5; The circumferencial direction of outer valve sleeve 6 relevant positions is provided with one group of throttle orifice 61, and how curved aperture runner designs to have avoided conventional high-tension modulating valve complications, has eliminated the runner dead angle; Increased negotiability, guaranteed that flow dontroller has stronger anti-plugging ability.
Alkaline stream is out-of-date in the instrument runner; Make spool 4, inner valve sleeve 5 and outer valve sleeve 6 owing to adopt nickel-bass alloy material to substitute traditional precipitation hardening steel; Nickel-base alloy has advantages such as high tenacity, high hardness, obdurability and strong corrosion resistant property; The flow dontroller of making so not only has good anticorrosion effect to alkali lye, and suitable high pressure operating mode is used.
