Embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, Fig. 1 is the utility model spool one embodiment's structural representation; Angle structural representation when Fig. 2 is the utility model spool the first water passage hole water inlet and outlet state; Another angle structural representation when Fig. 3 is the utility model spool the first water passage hole water inlet and outlet state; Angle structural representation when Fig. 4 is the utility model spool the second water passage hole water inlet and outlet state; Another angle structural representation when Fig. 5 is the utility model spool the second water passage hole water inlet and outlet state.
With reference to Fig. 1, Fig. 2 and Fig. 4, the utility model spool comprises spool body 10, the first water passage hole 20, aperture is greater than the second water passage hole 30 of the first water passage hole 10, on spool body 10, be also provided with rotating shaft 40, this rotating shaft 40 is provided with position limit pin 401, position limit pin 401 when being assembled on valve casing 70 to limit the pivotal position of spool, thereby by controlling spool, between the first water passage hole 20 and the second water passage hole 30, come back rotation to realize the size of controlling water flow.The noise producing when reducing spool water outlet, the water inlet area of the water intake of the first water passage hole 20 201 is arranged to be less than to the water-outlet area of the water outlet 202 of the first water passage hole 20, the water inlet area of the water intake 301 of the second water passage hole 30 is arranged to be less than or equal to the water-outlet area of the water outlet 302 of the second water passage hole 30.Particularly, the first water passage hole 20 and the second water passage hole 30 intersect on the axle center of spool body 10.Because the water inlet area of the water intake 201 of the first water passage hole 20 is less than the water-outlet area of the water outlet 202 of the first water passage hole 20, therefore at current through out-of-date, water intake 201 pressure of the first water passage hole 20 are reduced relatively, thereby can effectively reduce current through the first water passage hole 20 and the noise of generation.When the water inlet area of the water intake 301 of the second water passage hole 30 equals the water-outlet area of water outlet 302 of the second water passage hole 30, because the aperture ratio of the second water passage hole 30 is larger, the noise being produced by effect of water pressure can be not clearly yet.And when the water inlet area of the water intake 301 of the second water passage hole 30 is less than the water-outlet area of water outlet 302 of the second water passage hole 30, noise can be dropped to lower.
Further, for the convenient big or small conversion of controlling water flow, the shaft axis of the first water passage hole 20 is mutually vertical with the shaft axis of the second water passage hole 30.
Further, with reference to Fig. 1, Fig. 3 and Fig. 5, in order to reduce current noise, and make current be linear change, the outer wall of spool body 10 is provided with the annular groove 50 around spool body 10, this annular groove 50 is communicated with water intake 201 and the water outlet 202 of described the first water passage hole 20, and/or is communicated with water intake 301 and the water outlet 302 of described the second water passage hole 30.The degree of depth of annular groove 50 and width are according to required water flow setting.Preferably, the groove width of annular groove 50 is greater than the water inlet area of the water intake 201 of the first water passage hole 20, is less than the water-outlet area of the water outlet 302 of the second water passage hole 30.
In addition, shown in Fig. 4 and Fig. 5, the water intake 301 of the second water passage hole 30 of spool body 10 of take further illustrates current through the concrete condition of annular groove 50 for example as feed-water end.The shaft axis of the second water passage hole 30 of spool body 10 of take is reference point, the left and right sides that can see the shaft axis of the second water passage hole 30 all forms a curve bath, and crossed along water outlet 302 places of curve bath to the second water passage hole 30 by water intake 301 places of the second water passage hole 30, should be understood that the common makeup ring connected in star 50 of these two curve baths, specifically as shown in Figure 1.When current enter from the feed-water end (i.e. the water intake 302 of the second water passage hole 30) of water valve, current are divided into three parts, part water enters to water outlet 302 outflows of the second water passage hole 30 from the water intake 301 of the second water passage hole 30, the water outlet 302 that two-part flow into the second water passage hole 30 from the curve bath of the shaft axis left and right sides of the second water passage hole 30 respectively in addition crosses, now two strands of current are owing to mutually impacting the pressure of the water outlet that has reduced by the second water passage hole 30, and then have reduced the current noise of the water outlet 302 of the second water passage hole 30.When take the water intake 201 of the first water passage hole 20 of spool body 10 during as feed-water end, the example that the concrete condition of current process annular groove 50 can be feed-water end with reference to above-mentioned water intake 301 of take the second water passage hole 30, repeat no more, specifically as shown in Figures 2 and 3 herein.
Further, in order to make the flow impact face of the water outlet of the first water passage hole 20 or the second water passage hole 30 cover whole water outlet and to realize the current noise that two strands of current impact to reduce water outlet equably mutually, above-mentioned annular groove 50 is symmetrical up and down along the axle center horizontal plane of the first water passage hole 20 or the second water passage hole 30, as shown in Figure 1.
Further, with reference to Fig. 1, the first water passage hole 20 and/or the second water passage hole 30 and the crossover location of the bottom land of annular groove 50 are formed with the level and smooth cross section 60 that is communicated with.Because can making the first water passage hole 20 and/or the second water passage hole 30, arranging of annular groove 50 form thinner sharp edge with the cross section 60 that is communicated with of the bottom land of annular groove 50, when having current fast through this sharp edge, with regard to being likely subject to the impact of current, produce noise, therefore by the first water passage hole 20 and/or the second water passage hole 30 are put down or are polished with cross section 60 millings that are communicated with of the bottom land of annular groove 50, make to be communicated with the dull face that cross section 60 is certain width and has certain smoothness, for example, plane or curved surface, thus the generation of current noise can further be reduced.
Further, with reference to Fig. 1, above-mentioned rotating shaft 40 is formed in one with spool body 10.The mode that can certainly connect with pin-and-hole etc. is connected and fixed.And rotating shaft 40 is provided with position limit pin 401, the shaft axis 30 of this position limit pin 401 and the second water passage hole is 0-45 degree angle.Preferably, the shaft axis of position limit pin 401 and the second water passage hole 30 is 30 degree angles.This is in order to facilitate spool to coordinate with valve casing 70, thereby realizes to limit the pivotal position of spool the size of preferably controlling water flow.
The utility model also proposes a kind of water valve, and this water valve comprises above-mentioned spool, and the detailed structure of this spool can, with reference to above-described embodiment, repeat no more herein.Owing to having used above-mentioned spool in water valve, therefore, the utility model has solved the problem that water valve produces current noise in use, effectively reduces the noise pollution to people's daily life, and then more popular to people.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
