Description
Technical field
This utility model relates to hydraulic connecting technical field, is specifically related to a kind of anti-return reducing union joint.
Background technology
Hydraulic Elements are the vitals of construction machinery product, hydraulic system oil pipe is all that employing presses the form of (folder) plate by tight for the potted component pressure (folder) on pipeline in the interface plane of hydraulic part with hydraulic part interface, thus realizes hydraulic system and normally work；Owing to pressing plate is integrally fixed on the screwed hole of hydraulic part interface machined surface, indirectly the steel pipe interface of band sealing ring is pressed on the interface machined surface of hydraulic part by locking pressure plate；On the one hand, locking rear fender and interface surface certainly exist certain gap guarantee potted component and effectively compress；On the other hand, pressing plate belongs to standard component, and the machined surface form of hydraulic part and size are different, and different suppliers have different designs scheme；So the machined surface profile of the outline of pressing plate and hydraulic part is inconsistent, the outline being substantially hydraulic part is bigger than normal.Reducing union joint uses frequently during reducing, also brings flow simultaneously and changes rapidly, along with the sudden change of current, backflow change easily occurs.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, thering is provided a kind of simple in construction, a kind of anti-return reducing union joint reasonable in design, easy to use, it uses and arranges gear filter plate and sinuous flow layer in inclined tube, can Fast Segmentation current, form gap sinuous flow, reduce water flow impact pressure, the purpose of anti-backflow can be played simultaneously, and it has easy to use, simple to operate, the features such as practicality is good, with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-return reducing union joint described in the utility model, including inclined tube, small diameter tube and large-diameter pipe, two ends, described inclined tube left and right are provided with female thread, being provided with small diameter tube on the left of described inclined tube, right side is provided with large-diameter pipe, is provided with gear filter plate in described inclined tube, described gear filter plate is arranged on inside small diameter tube and large-diameter pipe, being provided with sinuous flow layer, the described trapezoidal cylinder of sinuous flow layer between described gear filter plate, described gear filter plate uses metal screen plate.
It is provided with ceramic bead in described sinuous flow layer, described ceramic bead particle diameter is 2-5mm, in sinuous flow layer, ceramic bead is set, when water flow through out-of-date, in sinuous flow layer, current are passed through in the gap between ceramic bead, and current are upset formation sinuous flow, owing to ceramic bead is rounded, the circular arc on surface can be substantially reduced resistance to water-flow.
It is provided with rubber ring between described gear filter plate and large-diameter pipe, described rubber ring is arranged on gear filter plate edge, the setting of rubber ring can be greatly increased the compact siro spinning technology between gear filter plate and large-diameter pipe, rubber ring is arranged on gear filter plate edge, contact with large-diameter pipe, the rigid damage of sealing effectiveness, the most anti-backstop filter plate and large-diameter pipe is increased by the rubber ring that presses the when of screw threads for fastening.
Using after said structure, this utility model has the beneficial effect that this utility model, and it uses and arranges gear filter plate and sinuous flow layer in inclined tube, it is possible to Fast Segmentation current, forms gap sinuous flow, reduces water flow impact pressure, can play the purpose of anti-backflow simultaneously；Sinuous flow layer, as main back-flow preventer, has good reducing effect；The gear filter plate using metal screen plate structure can utilize sieve plate mesh effect by current segmentation effect, and metal screen plate has good corrosion resistant and hardness simultaneously, and using effect is good, durable；And it has easy to use, simple to operate, the features such as practicality is good, with low cost.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in Figure 1, a kind of anti-return reducing union joint described in the utility model, including inclined tube 1, small diameter tube 2 and large-diameter pipe 3, described inclined tube about 1 two ends are provided with female thread 4, are provided with small diameter tube 2 on the left of described inclined tube 1, right side is provided with large-diameter pipe 3, being provided with gear filter plate 5 in described inclined tube 1, described gear filter plate 5 is arranged on inside small diameter tube 2 and large-diameter pipe 3, is provided with sinuous flow layer 6 between described gear filter plate 5, the described trapezoidal cylinder of sinuous flow layer 6, described gear filter plate 5 uses metal screen plate.
It is provided with ceramic bead 7 in described sinuous flow layer 6, described ceramic bead 7 particle diameter is 2-5mm, in sinuous flow layer, ceramic bead is set, when water flow through out-of-date, in sinuous flow layer, current are passed through in the gap between ceramic bead, and current are upset formation sinuous flow, owing to ceramic bead is rounded, the circular arc on surface can be substantially reduced resistance to water-flow.
It is provided with rubber ring 8 between described gear filter plate 5 and large-diameter pipe 2, described rubber ring 8 is arranged on gear filter plate 5 edge, the setting of rubber ring can be greatly increased the compact siro spinning technology between gear filter plate and large-diameter pipe, rubber ring is arranged on gear filter plate edge, contact with large-diameter pipe, the rigid damage of sealing effectiveness, the most anti-backstop filter plate and large-diameter pipe is increased by the rubber ring that presses the when of screw threads for fastening.
This utility model it use gear filter plate and sinuous flow layer be set in inclined tube, it is possible to Fast Segmentation current, form gap sinuous flow, reduce water flow impact pressure, the purpose of anti-backflow can be played simultaneously；Sinuous flow layer, as main back-flow preventer, has good reducing effect；The gear filter plate using metal screen plate structure can utilize sieve plate mesh effect by current segmentation effect, and metal screen plate has good corrosion resistant and hardness simultaneously, and using effect is good, durable；And it has easy to use, simple to operate, the features such as practicality is good, with low cost.
