Detailed Description
As shown in the attached drawings:
the invention provides a rotary valve type overflow valve with a wide pressure regulating range and strong anti-pollution capability, which comprises a valve body 4, an oil inlet 8 and an oil outlet 9, wherein a rotating sheet 1 is arranged at the top of the valve body 4, a bolt 3 is arranged on the surface of the top of the valve body 4, the rotating sheet 1 is connected with a threaded rod 2, the threaded rod 2 is connected with a cylinder 5 in the valve body 4, two spring steels 6 penetrate through the cylinder 5, the spring steels 6 are connected with a valve core 7, the bottom of the valve core 7 is connected with a blade 11, the blade 11 is connected with a cavity 12, the oil inlet 8 is connected with the cavity 12 through a small circular tube 10, the oil outlet 9 is connected with the cavity through another small circular tube, and the two cavities 12 are communicated through a U-shaped tube 13.
Wherein, the valve core 7 is provided with a groove.
Wherein, the oil inlet 8 is communicated with a small cavity 1201 in the cavity 12 through a small round pipe 10.
Wherein, the oil outlet 9 is communicated with a large cavity 1202 in the cavity 12 through a small round pipe.
Two U-shaped tubes 13 are provided, and the initial positions are communicated with two large cavities, wherein one U-shaped tube is arranged at the proximal end of the small cavity 1201, and the other U-shaped tube is arranged at the distal end of the small cavity 1201.
Wherein, the two ends of the blade 11 are respectively positioned in the cavity 12, and the inner part of the cavity 12 is divided into a small cavity 1201 and a large cavity 1202.
The working principle is as follows:
at first, the rotating piece 1 is rotated, so that the cylinder 5 is stressed, the spring steel 6 is indirectly stressed, the spring steel 6 finally enables the blade 11 to be stressed, the blade can only be rotated when the oil pressure reaches a certain degree, and the function of the overflow valve is further realized. After the rotating piece rotates, oil enters from the oil inlet 8, because small round tube 10 and the intercommunication thereof, oil enters into the small cavity 1201, then the part that the blade is located in the cavity 12 receives the pressure of oil pressure, push the blade tip towards big cavity 1202 to realize the rotation of blade, the rotation of blade drives the rotation of case 7, then make the recess on the case 7 rotate certain angle, oil can pass through the groove part, pass through fast, thereby reduce the oil pressure, make the oil pressure can not exceed the critical point. The invention has simple structure and safe and convenient use.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can cover the scope of the present invention without any changes or substitutions that may be made without inventive work within the technical scope disclosed in the present invention, and therefore, the scope of the present invention should be determined by the scope of the claims.
