Embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is described further:
To shown in Figure 7, the present invention is a kind of manual tune handle of valve with auto-lock function such as Fig. 1, and it comprises handle body 1, and handle body 1 links to each other with valve rod 3 in being installed in valve body 2, and valve rod 3 links to each other with spool for the unlatching of control valve and closure; At valve body 2 fixed base 4 is installed, this fixed base 4 is nested with outside valve rod 3, be provided with the draw-in groove 41 of a plurality of circular array in the upper-end surface of fixed base 4, handle body 1 places fixed base 4 tops and mobilizable being nested with to make 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 snap in draw-in groove corresponding with angle of swing on the fixed base 4 41 interior locking handle bodies 1 by drive unit 5 when 3 rotation of handle body 1 actuate valve stem; At fixed base 4 draw-in groove 41 of a plurality of circular array is set, handle body 1 and valve rod 3 are flexibly connected, utilize draw-in groove 41 phase clampings that lever principle presses limiting tooth 11 that handle body 1 makes handle body 1 and fixed base 4 and separate; When needs unlatching or regulating valve fluid flow, pressing handle body 1 one ends makes the limiting tooth 11 on the other end be separated with draw-in groove 41, can order about valve rod 3, the unlatching of spool synchronous interaction realization valve or the Flow-rate adjustment of fluid by rotatable handle body 1 like this, when being adjusted to correct position, release handle body 1, drive unit 5 just can order about the draw-in groove 41 phase clampings on limiting tooth 11 and the fixed base 4; Adopt this structure, not only can be convenient to the adjusting of valve fluid flow, simultaneously, also can adjust flux the time realize self-locking, guarantee the stability of Flow-rate adjustment, and easy operating simple in structure.
In the present embodiment, for ease of being fixedly connected with and reliability that handle body 1 and valve rod 3 are flexibly connected of fixed base 4 and valve body 2, be provided with block 6 at described fixed base 4, the bottom end of block 6 is fitted with fixed base 4 upper-end surfaces and is fixedly connected with valve rod 3 by bolt 61, because block 6 is arranged on fixed base 4 tops, and by bolt 61 with after valve rod 3 is fixedly connected with, the bottom end of block 6 will inevitably push up and press solidly reservation 4, so just can guarantee the connection reliability of fixed base 4 and valve body 2; In block 6, be provided with opening slot 62,6 synchronous interactions that handle body 1 places in the opening slot 62 and valve rod 3 is flexibly connected and handle body 1 is blocked a shot when actuate valve stem 3 rotation, opening slot 62 degree of depth are greater than handle body 1 thickness, and handle body 1 one ends can order about limiting tooth 11 and draw-in groove 41 clampings and separate along opening slot 62 upper and lower displacements; And at the block 6 interior opening slots 62 that arrange, handle body 1 is being nested with when valve rod 3 is outer like this, handle body 1 can place in the opening slot 62, utilize 62 pairs of handle bodies 1 of opening slot of block 6 to limit, prevent that handle body 1 and valve rod 3 are separated, improve stability in use, 6 be connected with valve rod 3 by bolt 61 and block a shot, when handle body 1 rotation, block 6 can rotate synchronously along axis and the handle body 1 of bolt 61, the clamping of assurance handle body 1 limiting tooth 11 and draw-in groove 41 when rotary valve rod 3 Open valves or adjust flux with separate; And the degree of depth of opening slot 62 is greater than the thickness of handle body 1, handle body 1 is when placing opening slot 62 interior like this, as when utilizing lever principle to press handle body 1 one ends and rotary valve rod 3 Open valves or regulating valve flow, handle body 1 two ends have enough activity spaces, guarantee the valve operation flexibility.
In the present embodiment, for ease of handle body 1 and the flexible connection of valve rod 3 and fixing of handle body 1, described valve rod 3 ends are square, and handle body 1 is provided with square hole 12, and square hole 12 width are greater than valve rod 3 end width and be nested with outside the squared ends of valve rod 3 and valve rod 3 flexible connections; Cooperate by the squared ends that is arranged on square hole 12 on the handle body 1 and valve rod 3, when can guarantee that like this handle body 1 is flexibly connected with valve rod 3, handle body 1 two ends can be along valve rod 3 upper and lower displacements, the phase clamping that realizes limiting tooth 11 and draw-in groove 41 with separate; Both sides in handle body 1 upper aperture 12 are provided with pin-and- hole 13, and 6 are provided with tapped hole 63 on block, and the bearing pin 64 in end insertion handle body 1 pin-and-hole 13 is installed in the tapped hole 63, and these bearing pin 41 the other ends are threaded with the tapped hole 63 of block 6; And pin-and-hole 13 is set in the both sides of handle body 1, tapped hole 63 is set and by pin-and-hole 13 handle body 1 is hinged in the opening slot 62 of block 6 at block 6, like this when guaranteeing that handle body 1 and valve rod 3 are flexibly connected, also can guarantee the connection reliability of handle body 1 and block 6, improve the operational stability of handle body 1.
In the present embodiment, behind Open valve or adjust flux, can realize auto-lock function for guaranteeing handle body 1, described drive unit 5 is spring, spring one end is fixed in the spring seat 621 of groove bottom of block 6 opening slots 62, and the other end compresses mutually with handle body 1 end face and orders about limiting tooth 11 and draw-in groove 41 phase clampings; Opening slot 62 interior spring is set and make spring one end and handle body 1 limiting tooth 11 1 ends with compress, like this behind 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 of draw-in groove 41 interior realization valves corresponding on the fixed base 4 automatically.
In the present embodiment, because fixed base 4 is to fix with valve body 2 with being fastenedly connected of valve rod 3 by the bolt 61 of blocking a shot on 6, for preventing that handle body 1 is when rotary valve rod 3 Open valves or the adjust flux, fixed base 4 rotates synchronously with handle body 1, described fixed base 4 bottoms are provided with and are buckled in the fixed groove 42 that prevents fixed base 4 rotation on the valve body 2, are provided with metallic shim 43 at the junction point of this fixed groove 42 and valve body 2; By in fixed base 4 bottoms fixed groove 42 being set, fixed groove 42 may be stuck in the adpting flange both sides of valve left and right sides valve body 2 like this, when handle body 1 during at rotary valve rod 3 Open valves or adjust flux, be subjected to the restriction of fixed groove 4, fixed base 4 can be with handle body 1 and block 6 synchronous interactions, so just can guarantee handle body 1 when rotated the limiting tooth 11 of its end can be connected to fixing draw-in groove 41 interior realization auto-lock functions; Can effectively prevent friction between fixed base 4 and the valve body 2 and at the junction point of fixed groove 4 and valve body 2 metallic shim 43 is set.
In the present embodiment, because when handle body 1 rotary valve rod, 3 Open valves or adjust flux, block 6 rotates synchronously with handle body 1, in order to reduce the frictional force between block 6 and the fixed base 4, described block 6 bottoms are provided with top briquetting 64, be provided with packing ring 45 in the circular groove 44 in fixed base 4, top briquetting 64 fits with packing ring 45 end faces; By cooperating of top briquetting 64 and packing ring 45, can reduce to the full extent the friction between block 6 and the fixed base 4, can effectively prolong the working life of valve.
Draw-in groove 41 quantity on the fixed base 4 can be decided according to the needs that valve flow is regulated class or user, and the present invention is not further qualified.
Above-described embodiment should not be considered as limitation of the present invention, but any improvement of doing based on spirit of the present invention, all should be within protection scope of the present invention.
