Abstract
The present invention relates to a throttle joint, which comprises a filtration screen and a body provided with a center hole, wherein the center hole is divided into a light hole and a threaded hole, and a throttle pad is arranged inside the threaded hole. The throttle joint is characterized in that the filtration screen is arranged on one light hole end connected with the external, the filtration screen and the light hole are fixedly connected through threads, both surfaces of the throttle pad are respectively provided with a front transition surface and a rear transition surface, the front transition surface is arranged on one side close to the light hole, the rear transition surface is arranged on one side away from the light hole, and the front transition surface and the rear transition surface are inclined planes forming an inclination angle of 30-60 DEG with a radial direction. According to the present invention, the filtration screen is arranged on the outer side, replacement is easy, water flowing is stable with the front transition surface and the rear transition surface, and a throttling effect is good.
Description
Technical field
The present invention relates to a kind of throttling joint.
Background technology
At present, the water yield of shower nozzle or water tap all has the user to control voluntarily, but the water yield of shower nozzle or water tap is more big in actual use, can not represent and just have higher relatively cleaning effect, and the water yield of appropriateness not only has good cleaning effect, can also save charges for water and electricity, this meets present environmental protection concept.But existing throttling joint in actual use, throttle orifice the situation, particularly rural subscribers stopped up occur in use easily, because the water source is directly in drainage on the mountain or extract in well water, so impurity content is more relatively, and then the situation that makes the easier appearance obstruction of throttle orifice.
In order to address this problem, the throttling joint that some improveds are also arranged, as Chinese patent, a kind of throttling joint (201220135464.X), a kind of throttling joint, it comprises the body that is provided with centre bore, described centre bore is divided into unthreaded hole and screwed hole, the aperture of unthreaded hole is less than the aperture of screwed hole, be provided with the throttling pad in the described screwed hole, and the diameter of throttling pad is greater than the aperture of unthreaded hole, described throttling pad is provided with axial throttle orifice, be provided with filter screen between described throttling pad and the unthreaded hole, the diameter of described filter screen is greater than the aperture of unthreaded hole.
But above-mentioned existing invention remains at filter screen and is arranged on screwed hole inside, changes inconveniently, and the throttling pad has only a transition face, the shortcoming that current can not smooth flow.
Summary of the invention
Remain at filter screen and be arranged on screwed hole inside in order to overcome existing invention, change inconveniently, the throttling pad has only a transition face, and the shortcoming that current can not smooth flow the invention provides a kind of throttling joint.
The technical solution adopted for the present invention to solve the technical problems is: a kind of throttling joint, its composition comprises filter screen, be provided with the body of centre bore, described centre bore is divided into unthreaded hole and screwed hole, be installed in the throttling pad in the screwed hole, it is characterized in that: described filter screen is installed in the end that unthreaded hole links to each other with the external world; Rely between described filter screen and the unthreaded hole be threaded fixing; Transition face and back transition face before described throttling pad two sides is respectively equipped with; Preceding transition face is arranged on the side near unthreaded hole; Back transition face is arranged on the side away from unthreaded hole; Preceding transition face with the back transition face is and the inclined-plane that radially becomes 30-60 ° of inclination angle.
The invention has the beneficial effects as follows: filter screen is arranged on the outside, and it is convenient to change, and former and later two transition faces make flow steady, good throttle effect.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of structural representation of throttling joint.
Fig. 2 is a kind of structural representation of throttling pad of throttling joint.
Among Fig. 1-Fig. 2,1. unthreaded hole, 2. before transition face, 3. body, 4. screwed hole, 5. throttle orifice, 6. back transition face, 7. throttling pad, 8. filter screen 9. is threaded, 10. projection.
The specific embodiment
In Fig. 1-Fig. 2, a kind of throttling joint, its composition comprises filter screen 8, be provided with the body 3 of centre bore, described centre bore is divided into unthreaded hole 1 and screwed hole 4, be installed in the throttling pad 7 in the screwed hole 4, described filter screen 8 is installed in the end that unthreaded hole 1 links to each other with the external world, rely between described filter screen 8 and the unthreaded hole 1 be threaded 9 fixing, transition face 2 and back transition face 6 before described throttle orifice 7 two sides are respectively equipped with, preceding transition face 2 is arranged on the side near unthreaded hole 1, back transition face 6 is arranged on the side away from unthreaded hole 1, and preceding transition face 2 is and the inclined-plane that radially becomes 30-60 ° of inclination angle that the center of throttling pad 7 is provided with throttle orifice 5 with back transition face 6, the excircle of throttling pad 7 is provided with projection 10, and projection 10 plays the effect of location throttling pad 7.
During use, current flow into unthreaded hole 1 by filter screen 8, and transition face 2 before flowing to again through the drainage of preceding transition face 2, flows into throttle orifice 5, flows out from back transition face 6 then, and back transition face 6 plays the effect of unhurried current, flows into screwed hole 4 again, reaches the effect of throttling.Experiment showed, current transition face 2 and back transition face 6 for when radially becoming the inclined-plane at 30-60 ° of inclination angle, restriction effect is best.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
