Abstract
The utility model relates to a throttling valve and aims to provide a mini-adjustable valve capable of performing mini adjustment on flow and meeting a control requirement. The mini-adjustable valve comprises a valve body, a valve core, a valve cover and an adjusting hand wheel, wherein the valve cover is in threaded connection with the upper part of the valve body; an oil inlet is formed at the bottom of the valve body; an oil outlet is formed on the side of the valve body; the valve core stretches into the valve body, and the bottom of the valve core is communicated with the oil inlet; and the adjusting hand wheel is fixed at the top of the valve core through screws. During rotation of the adjusting hand wheel, the adjusting hand wheel drives the valve core to lift or descend, and a clearance is formed between the valve core and the valve body, so that high-pressure oil flows from the oil inlet to the oil outlet, and the flow is adjusted by the number of rotating turns of the adjusting hand wheel. During anticlockwise rotation of the adjusting hand wheel, the valve core lifts, and the clearance is formed between the valve core and the valve body, so that the high-pressure oil flows from the oil inlet to the oil outlet, and the flow is adjusted by the number of rotating turns of the adjusting hand wheel. Because the duration of coordination of the valve core and the valve body is quite long, the flow can be subjected to mini adjustment.
Description
Technical field
The utility model relates to a kind of throttle, particularly relates to a kind of micro-modulating valve.
Background technique
Domestic lime rotary kiln adopts the hydraulic drive catch wheel device to bear the sliding force of full kiln, and kiln body diameter is 4m, long 60m, and the content material, and because of the kiln body tilts to place, so the trend of downslide is arranged under the deadweight effect.Adopt hydraulic thrust shelves wheel, make the kiln body (be generally 2～3mm/h) and force to scurry and controlledly glide, thereby guarantee to take turns the even contact and the wearing and tearing of band and support roller effectively, save the workload of support roller adjustment greatly by the speed of envisioning.When rotary kiln rises to certain position; The pump fuel cut-off, Solenoid ball valve gets electric, leans on the deadweight of kiln body; Make that original pressure oil flows back to fuel tank through flow control valve in the oil cylinder; The speed that the kiln body glides is mainly controlled by flow control valve, and because of the extremely slowly about 2-3mm/h of speed that requires the kiln body to glide, existing common throttle valve is difficult to satisfy the control requirement.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of can carry out the trace adjusting to flow, satisfies the micro-modulating valve that control requires.
The micro-modulating valve of the utility model comprises valve body, spool, valve gap and adjusting handle, and said valve gap is threaded in the top of valve body; The bottom of said valve body is provided with filler opening, and the sidepiece of valve body is provided with oil outlet, and said spool extend in the valve body and the bottom is communicated with filler opening; Said adjusting handle is through the top of screw at spool; When rotating adjusting handle, adjusting handle drives spool and rises or descend, by producing the slit between spool and valve body; Make high pressure oil flow the size of regulating flow through the number of turns of rotation adjusting handwheel to oil outlet by filler opening.
The micro-modulating valve of the utility model, said valve body and spool adopt taper fit.
The micro-modulating valve of the utility model is provided with an O RunddichtringO in the end face joint of valve body and valve gap.
The micro-modulating valve of the utility model, said spool is provided with seal groove, is provided with the 2nd O RunddichtringO in the seal groove.
The micro-modulating valve of the utility model, the position of matching with valve body in the bottom of said spool is provided with balance and crosses oil groove.
The micro-modulating valve of the utility model all is provided with connecting thread on said filler opening and the oil outlet, connecting thread is convenient to be connected with on-the-spot pipeline.
Compared with prior art the beneficial effect of the utility model is: when being rotated counterclockwise adjusting handle, spool rises, and produces the slit between spool and valve body, and high pressure oil is flowed to oil outlet by filler opening; The size of flow is by the number of turns decision of adjusting handle.Otherwise when clockwise adjusting handle, spool descends, and the slit diminishes between spool and valve body, and high pressure oil diminishes to the flow that oil outlet flows from filler opening, until shutoff, because of spool and valve body length of thread engagement are very long, so can carry out micro-Flow-rate adjustment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1, a kind of micro-modulating valve comprises valve body 1, spool 2, valve gap 3 and adjusting handle 5; Valve body 1 adopts taper fit with spool 2; Valve gap 3 is threaded in the top of valve body 1, and the bottom of valve body 1 is provided with filler opening 11, and the sidepiece of valve body 1 is provided with oil outlet 12; All be provided with connecting thread 121 on filler opening 11 and the oil outlet 12, connecting thread 121 conveniently is connected with on-the-spot pipeline;
Spool 2 extend in the valve body and the bottom is communicated with filler opening 11; The position of matching with valve body 1 in the bottom of spool 2 is provided with balance and crosses oil groove 21; Adjusting handle 5 is fixed on the top of spool 2 through screw 4, and when rotating adjusting handle 5, adjusting handle 5 drives spools 2 and rises or descend; Take high pressure oil to by spool 2 and 1 generation of valve body slit and flow the size of regulating flow through the number of turns of rotation adjusting handwheel 5 to oil outlet 12 by filler opening 11.
End face joint at valve body 1 and valve gap 3 is provided with an O RunddichtringO 6 that prevents hydraulic fluid leak, and spool 2 is provided with seal groove 22, is provided with the 2nd O RunddichtringO 7 that can prevent hydraulic fluid leak in the seal groove 22.
The working procedure of the utility model trace modulating valve is following:
When being rotated counterclockwise adjusting handle 5, spool 2 rises, and 1 of spool 2 and valve body produce the slit, and high pressure oil is flowed to oil outlet 12 by filler opening 11; The size of flow is by the number of turns decision of adjusting handle 5.Otherwise when clockwise adjusting handle 5, spool 2 descends; 1 slit of spool 2 and valve body diminishes, and high pressure oil diminishes to the flow that oil outlet 12 flows from filler opening 11, until shutoff; Because of spool 2 and valve body 1 length of thread engagement are very long, so can carry out the Flow-rate adjustment of trace.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
