Description of drawings
Structural representation when Fig. 1 is in maximum opening state for the utility model anti-plugging finely regulating valve,
Structural representation when Fig. 2 is in closed condition for the utility model anti-plugging finely regulating valve
Among the figure: the 1-valve body, the 2-valve port, the 3-valve ball, the 4-cylinder, the 5-rectangular opening, 6-dial indication body, the 7-dial, the 8-valve rod, 9-connects cutting ferrule, 10-packing seal letter, 11-valve gap, 12-sealing opening ring.
Embodiment
For clearly demonstrating the scheme in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.
As shown in Figure 1, anti-plugging finely regulating valve comprises valve body 1, valve rod 8 and spool; Said valve body portion within it is provided with valve port 2, and the internal diameter of said valve port 2 is 14mm, and said spool comprises cylinder 4; The end sealing that cylinder 4 is connected with valve rod 8, cylinder 4 outer walls and said valve port 2 inwalls form sealing surface, and on said cylinder 4 outer walls, having width is 1mm; Highly be the rectangular opening 5 of 10mm, the inwall of said valve port 2 and said rectangular opening 5 dynamic fit are controlled the actual internal area of said rectangular opening 5.
As shown in Figure 1, for anti-plugging finely regulating valve is in maximum rating, when being in this state, can realize major path (14mm) releasing obstruction, the new fluid blockage of irrigation channel is explained by oneself, passage can wash voluntarily, clean.
Above-mentioned anti-plugging finely regulating valve, said spool also comprise the valve ball 3 that cylinder 4 sealed ends are provided with, and the diameter of valve ball 3 is bigger than the diameter of cylinder 4; Said valve port 2 is provided with sealing opening ring towards an end of valve rod 8; Said sealing opening ring cooperates the said valve port 2 of shutoff with valve ball 3, said valve port 2 is the sealed step hole, when said rectangular opening (5) protrusion turn-offs valve ports 2 at said valve ball 3; The distance of the sealing surface 1mm in the said sealed step of said rectangular opening 5 protrusions hole; When said valve ball 3 separated with said step hole, the fluid cross-section through rectangular opening 5 is long-pending just in time be 1mm2, made that can accurately control 1 to 10mm fluid cross-section amasss.
Above-mentioned anti-plugging finely regulating valve; Outside said valve body, be with dial indication body 6; Said dial 7 indication bodies are installed on the valve rod 8, on said valve body 1 outer wall, are carved with dial 7, and said spool is connected with said valve rod 8 through connecting cutting ferrule 9; Between said valve body 1 and said valve rod 8, be provided with packing seal letter 10; Along with moving up and down of valve rod 8, scale indication body 6 also moves up and down along with valve rod 8 and then makes scale indication body 6 lower limbs be parked on some scales of relative dial 7 reaching the effect of real-time indication spool aperture, and valve rod 8 and spool link together and make when valve rod 8 rotations through being connected cutting ferrule 9; Spool can not rotate thereupon together, so water hole 5 remains on a uniform numerical value over against the feasible flow rate of water flow through water hole 5 of some directions all the time.
