Description
Technical field
The present invention relates to the micro-resistance safety check of axle spring, be applicable to all liq and gas medium, belong to synthetic energy-saving discharge-reducing technical field and safety check technical field.
Background technique
Safety check is in many pipe conveying procedures, for preventing the conventional valve carrying liquid or gas backflow, but existing safety check is commercially all after being backed down by liquid or gas pressure, needs the surge pressure of working fluid or gas to keep opening of check valve plate always, which consumes suitable energy and pressure drop, although the safety check valve plate had now is very thin, very gently, when liquid or gas flow through in valve, pressure drop is less, power consumption is lower, and this safety check, because the too thin easy distortion of valve plate, affects the sealing of valve plate, the effect not having non-return had, now commercially only has the patent of invention " 201210054615.3 energy-saving micro-resistance adjustable self-balancing check valve " of uncle minister in ancient times Wei, " 201120251731.5 safety check " no longer can consume pressure drop and open to keep valve plate after opening valve plate, but these safety check also have a shortcoming, that is exactly after the valve plate of safety check will almost be opened completely, non-resistance or micro-resistance could be realized, that is when safety check does not reach full production in production is used, this kind of micro-resistance safety check just cannot realize the function of micro-resistance, and the patent of invention of Wei Baiqing " the permanent micro-resistance safety check of 201410044392.1 self-regualting types ", " in 201410059609.6 the permanent micro-resistance safety check of mode ", " 201410131870.2 permanent micro-resistance selfsealings safety check " overcomes this shortcoming, the any aperture opened at safety check or state, all only has small valve plate resistance or valveless plate resistance power, but this several safety check needs the structure changing valve body significantly, give to produce and increase cost, the present invention is under the constant condition of original valve body structure, the structure that the micro-resistance realizing safety check runs.
Summary of the invention
The object of this invention is to provide a kind of for liquid or gas circulation can have discharge pressure at the suction flange of safety check and open valve plate to no longer consume after any opening state pressure drop to keep this valve plate opening state and automatically can close valve plate in time when the suction flange of safety check does not have discharge pressure to stop the micro-resistance safety check of the axle spring of liquid or gas backstreaming.
The micro-resistance safety check of axle spring, comprise a valve body and the valve shaft be arranged in valve body, one be enclosed within the valve plate axle sleeve outside valve shaft, the valve plate be connected with valve plate axle sleeve and be arranged on valve plate axle sleeve both sides and be enclosed within two springs outside valve shaft; It is characterized in that:
1, valve shaft is arranged on the both sides of valve import, valve plate axle sleeve is shorter and be enclosed within the central authorities of valve shaft, valve plate axle sleeve is connected with valve plate, outside two ends, valve plate axle sleeve left and right, equal car has valve plate axle sleeve outside thread, the two ends externally threaded threaded portion of valve plate axle sleeve is distributed with many valve plate axle sleeve outer channel equably, the axis parallel of valve plate axle sleeve outer channel and valve plate axle sleeve, outside valve shaft on the left of valve plate axle sleeve, cover has a left positioning shaft sleeve, outside valve shaft on the right side of valve plate axle sleeve, cover has a right positioning shaft sleeve, the effect of positioning shaft sleeve is the middle position making valve plate axle sleeve be in valve shaft all the time, a left spring is installed outside left positioning shaft sleeve, the left end of left spring is fixedly mounted in valve body inner left wall, the right-hand member of left spring is fixedly mounted on the left end of left-handed cap, a right spring is installed outside right positioning shaft sleeve, the right-hand member of right spring to be fixedly mounted on the right side of valve body on inwall, the left end of right spring is fixedly mounted on the right-hand member of dextrorotation cap, the valve plate axle sleeve outside thread of valve plate axle sleeve left end has screwed a left-handed cap, the left end opening sleeve of left-handed cap also can be freely movable on left positioning shaft sleeve, rotating left-handed cap can make left-handed cap move left and right on valve plate axle sleeve outside thread, a left-handed cap setscrew is installed outside the right-hand member of left-handed cap, screwing left-handed cap setscrew can make left-handed cap setscrew be squeezed in the valve plate axle sleeve outer channel in valve plate axle sleeve left end valve plate axle sleeve outside thread region, thus makes left-handed cap be fixed on valve shaft to put and do not move, the valve plate axle sleeve outside thread of valve plate axle sleeve right-hand member has screwed a dextrorotation cap, the right-end openings of dextrorotation cap is enclosed within also can be freely movable on right positioning shaft sleeve, rotating dextrorotation cap can make dextrorotation cap move left and right on valve plate axle sleeve outside thread, a dextrorotation cap setscrew is installed outside the left end of dextrorotation cap, screwing dextrorotation cap setscrew can make dextrorotation cap setscrew be squeezed in the valve plate axle sleeve outer channel in valve plate axle sleeve right-hand member valve plate axle sleeve outside thread region, thus makes dextrorotation cap be fixed on valve shaft to put and do not move, rotate the adjustable left spring of left-handed cap and act on the rotating elastic that valve interior wall and valve shaft put, rotate the rotating elastic that the adjustable right spring action of dextrorotation cap puts in valve interior wall and valve shaft, the right-hand member right hand edge designing left-handed cap is fixed on the externally threaded screw thread middle position of valve plate axle sleeve of left section of valve plate axle sleeve, when the left end left hand edge of dextrorotation cap is fixed on the valve plate axle sleeve of right section of valve plate axle sleeve externally threaded screw thread middle position, the power of two spring actions on the valve plate sealing inclined-plane that the gravity that the rotating force that valve shaft puts overcomes valve plate makes valve plate act on valve body is zero, regulate the position of left-handed cap and dextrorotation cap, the rotating force that two spring actions can be regulated to put in valve shaft the gravity overcoming valve plate are with the size regulating valve plate to act on the power on valve plate sealing inclined-plane.
2, there is an angle α valve plate sealing inclined-plane and valve import medial axis, 5o≤α≤45o.
The present invention compared with prior art has the following advantages:
