Description
Technical field
The present invention relates to spring to decline resistance safety check, 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 when the suction flange of safety check does not have discharge pressure in time and to decline resistance safety check to stop the spring of liquid or gas backstreaming.
Spring declines resistance safety check, comprise a valve body and be arranged on a valve shaft 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 a positioning support between valve plate and valve shaft on valve plate neck, the one piece of spring support plate be vertically mounted on positioning support, hard-wired two springs in spring support plate two ends; It is characterized in that:
1, valve plate neck fixedly mounts a positioning support, positioning support is perpendicular to valve plate neck, and be arranged on valve plate neck away from valve import side, positioning support there is multiple uniform positioning hole, positioning hole perpendicular to positioning support and with valve plate neck axis parallel, on positioning support, cover has one piece of spring support plate, the center hole of spring support plate is square hole and is enclosed within positioning support, the center hole central shaft of spring support plate is vertical with spring support plate and overlapping with positioning support medial axis equality, the center square hole of uprighting spring support plate has a screw, standing screw is through this screw and through after the positioning hole on positioning support, fixed by a nut, spring support plate is enclosed within positioning support fixing, the center square hole rectangle length of long sides of spring support plate is greater than positioning support cross section rectangle length of long sides, the center square hole rectangle length of short sides of spring support plate is greater than positioning support cross section rectangle length of short sides, spring support plate is made to be enclosed within swing positioning support can done and be parallel to direction, positioning support medial axis, thus make the spring at spring support plate two ends once appearance height and elastic force unequal, the power of two spring-loaded spring support plates is also uneven, but because spring support plate is enclosed within swing positioning support can done and be parallel to direction, positioning support medial axis, so valve plate neck and valve plate all there will not be off-set phenomenon, and make valve plate still can when closing safety check and valve plate seal inclined-plane and seal completely, spring support plate two ends are respectively provided with a spring near valve import side, spring one end is fixed on spring support plate downside, the other end is fixed on the valve inwall on the upside of valve inlet tube, the central sleeve of often propping up spring has a guide rod, the upper length that spring support plate is stretched out through the hole on spring support plate in guide rod one end is L, 10cm > L > 1cm, the guide rod the other end is connected by running shaft with the valve inwall on the upside of valve inlet tube, guide rod can be swung along direction, valve plate neck medial axis, thus in valve plate opening and closing process, valve plate drives valve plate neck to rotate around valve shaft, and drive spring support plate to move and Tension and Compression spring, make guide rod in spring ring and drive spring to swing, regulate standing screw through position of positioning hole, the i.e. position of Regulation spring support plate on positioning support on positioning support, the distance of adjustable springs support plate distance spring and valve inwall tie point, thus regulate the state of compression or extension spring, the pressure Q that valve plate can be made to be pressed against on valve plate sealing inclined-plane is zero, also valve plate can be made to be pressed against pressure Q on valve plate sealing inclined-plane: or be less than 50g or be less than 100g or be less than the less numeral such as 200g, and then the micro-resistance realizing safety check runs.
2, there is an angle α valve plate sealing inclined-plane and valve import medial axis, 5o≤α≤45 o.
The present invention compared with prior art has the following advantages:
1. do not need the structure changing existing valve body, do not increase the Valve Block Mould production costs occupying larger cost.
2. pure mechanical structure, spring regulates simply, not fragile, volume is little, stable performance.
3, because spring support plate is enclosed within swing positioning support can done and be parallel to direction, positioning support medial axis, so when the spring force at spring support plate two ends is unequal, valve plate can not be made to depart from the position of valve plate sealing inclined-plane sealing.
