Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further:
As shown in Figures 1 to 7, the present invention is a kind of valve manual tune handle with auto-lock function, and it comprises handle body 1, and handle body 1 is connected with the valve rod 3 be arranged in valve body 2, and the unlatching that valve rod 3 is connected with spool for control valve is with closed; Valve body 2 is provided with fixed base 4, this fixed base 4 is nested with outside valve rod 3, the draw-in groove 41 of multiple circular array is provided with in the upper-end surface of fixed base 4, handle body 1 is placed in above fixed base 4 and mobilizable being nested with makes valve rod 3 and handle body 1 synchronous interaction outside valve rod 3, be provided with limiting tooth 11 in the end of handle body 1, this limiting tooth 11 can be snapped in draw-in groove 41 corresponding with angle of swing on fixed base 4 by drive unit 5 when handle body 1 actuate valve stem 3 rotates and lock handle body 1; Fixed base 4 arranges the draw-in groove 41 of multiple circular array, handle body 1 is flexibly connected with valve rod 3, utilize lever principle to press handle body 1 and make the draw-in groove 41 phase clamping of the limiting tooth 11 of handle body 1 and fixed base 4 and be separated; When needs unlatching or regulating valve fluid flow, pressing handle body 1 one end makes the limiting tooth 11 on the other end be separated with draw-in groove 41, like this can rotatable handle body 1 orders about valve rod 3, spool synchronous interaction realizes the unlatching of valve or the Flow-rate adjustment of fluid, when being adjusted to correct position, release handle body 1, drive unit 5 just can order about limiting tooth 11 and the draw-in groove 41 phase clamping on fixed base 4; Adopt this structure, not only can be convenient to the adjustment of valve fluid flow, meanwhile, also can adjust flux time realize self-locking, guaranteed flow regulate stability, and structure be simply easy to operation.
In the present embodiment, being fixedly connected with and reliability that handle body 1 is flexibly connected with valve rod 3 for ease of fixed base 4 and valve body 2, described fixed base 4 is provided with block 6, the bottom end of block 6 pastes merga pass bolt 61 with fixed base 4 upper-end surface and is fixedly connected with valve rod 3,6 be arranged on above fixed base 4 owing to blocking a shot, and after being fixedly connected with valve rod 3 by bolt 61, the bottom end of block 6 will inevitably push up and press solidly reservation 4, the connection reliability of fixed base 4 and valve body 2 so just can be ensured; Opening slot 62 is provided with in block 6, handle body 1 is placed in opening slot 62 and is flexibly connected 6 synchronous interactions and handle body 1 is blocked a shot when actuate valve stem 3 rotates with valve rod 3, opening slot 62 degree of depth is greater than handle body 1 thickness, and handle body 1 one end can be ordered about limiting tooth 11 and draw-in groove 41 clamping along opening slot 62 upper and lower displacement and be separated; And opening slot 62 is set in block 6, handle body 1 is being nested with when valve rod 3 is outer like this, handle body 1 can be placed in opening slot 62, opening slot 62 pairs of handle bodies 1 of block 6 are utilized to limit, handle body 1 and valve rod 3 is prevented to be separated, improve stability in use, and block a shot and 6 to be connected with valve rod 3 by bolt 61, when handle body 1 rotates, block 6 can along the axis of bolt 61 and handle body 1 synchronous axial system, the clamping of guarantee handle body 1 limiting tooth 11 and draw-in groove 41 when rotary valve rod 3 Open valve or adjust flux be separated; And the degree of depth of opening slot 62 is greater than the thickness of handle body 1, such handle body 1 is when being placed in opening slot 62, as utilize lever principle press handle body 1 one end and rotary valve rod 3 Open valve or regulating valve flow time, handle body 1 two ends have enough activity spaces, ensure valve operation flexibility.
In the present embodiment, for ease of handle body 1 and being flexibly connected of valve rod 3 and fixing of handle body 1, described valve rod 3 end is square, and handle body 1 is provided with square hole 12, and square hole 12 width is greater than valve rod 3 end portion width and is nested with and is flexibly connected with valve rod 3 the squared ends of valve rod 3 is outer; Coordinated by the squared ends being arranged on square hole 12 on handle body 1 and valve rod 3, while can ensureing that handle body 1 is flexibly connected with valve rod 3 like this, handle body 1 two ends can along valve rod 3 upper and lower displacement, the phase clamping realizing limiting tooth 11 and draw-in groove 41 be separated; Be provided with pin-and-hole 13 in the both sides of handle body 1 upper aperture 12, on block, 6 are provided with tapped hole 63, and be provided with the bearing pin 64 in one end insertion handle body 1 pin-and-hole 13 in tapped hole 63, this bearing pin 41 the other end is threaded with the tapped hole 63 of block 6; And pin-and-hole 13 is set in the both sides of handle body 1, block 6 arranges tapped hole 63 and by pin-and-hole 13, handle body 1 is hinged in the opening slot 62 of block 6, like this while guarantee handle body 1 is flexibly connected with valve rod 3, also can ensure handle body 1 and the connection reliability of block 6, improve the operational stability of handle body 1.
In the present embodiment, for ensureing that handle body 1 can realize auto-lock function after Open valve or adjust flux, described drive unit 5 is spring, spring one end is fixed in the spring seat 621 of the groove bottom of block 6 opening slot 62, and the other end and handle body 1 end face compress mutually and order about limiting tooth 11 and the clamping of draw-in groove 41 phase; Spring is set in opening slot 62 and makes spring one end and handle body 1 limiting tooth 11 one end and compress, like this when after rotatable handle body 1 Open valve or adjust flux, under the elastic force effect of spring, limiting tooth 11 can snap in the self-locking realizing valve in draw-in groove 41 corresponding on fixed base 4 automatically.
In the present embodiment, because fixed base 4 is bolts 61 by blocking a shot on 6 and being fastenedly connected of valve rod 3 and fixing with valve body 2, for preventing handle body 1 when rotary valve rod 3 Open valve or adjust flux, fixed base 4 and handle body 1 synchronous axial system, be provided with the fixed groove 42 being buckled in and valve body 2 prevents fixed base 4 from rotating bottom described fixed base 4, be provided with metallic shim 43 at this fixed groove 42 with the junction point of valve body 2; By arranging fixed groove 42 bottom fixed base 4, such fixed groove 42 may be stuck in the adpting flange both sides of valve left and right valve body 2, when handle body 1 is at rotary valve rod 3 Open valve or adjust flux, by the restriction of fixed groove 4, fixed base 4 can not with handle body 1 and block 6 synchronous interactions, so just can ensure handle body 1 when rotated the limiting tooth 11 of its end can be connected in fixing draw-in groove 41 and realize auto-lock function; And the friction that metallic shim 43 can effectively prevent between fixed base 4 and valve body 2 is set at the junction point of fixed groove 4 and valve body 2.
In the present embodiment, during due to handle body 1 rotary valve rod 3 Open valve or adjust flux, block 6 and handle body 1 synchronous axial system, in order to reduce the frictional force between block 6 and fixed base 4, top briquetting 64 is provided with bottom described block 6, be provided with packing ring 45 in circular groove 44 in fixed base 4, top briquetting 64 fits with packing ring 45 end face; By coordinating of top briquetting 64 and packing ring 45, the friction between block 6 and fixed base 4 can be reduced to the full extent, effectively can extend the working life of valve.
Draw-in groove 41 quantity on fixed base 4 can regulate the needs of class or user according to valve flow and determine, and the present invention is not further qualified.
Above-described embodiment should not be considered as limitation of the present invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
