Disclosure of Invention
The invention aims to solve the technical problems that the existing overflow valve has wide pressure range, strong pollution resistance, low cost and high cost performance, and can be used for manually adjusting pressure conveniently.
The invention discloses a Jiang Zhuaifa overflow valve with wide pressure regulating range and pollution resistance, which is prepared by the following technical means:
the utility model provides a wide antipollution ability Jiang Zhuaifa formula overflow valve of pressure regulating scope, includes valve body, oil inlet, oil-out, the valve body top is equipped with the rotary piece to valve body top surface is equipped with the bolt, the rotary piece is connected with the threaded rod, the threaded rod is connected with the inside cylinder of valve body, pass two spring steels on the cylinder, spring steels is connected with the case, the case bottom is connected with the blade, the blade is connected with the cavity, the oil inlet is connected with the cavity through little pipe, the oil-out is connected with the cavity through another little pipe, the cavity is equipped with two, communicates through U type pipe.
Preferably, the valve core is provided with a groove.
Preferably, the oil inlet is communicated with a small cavity in the cavity through a small circular tube.
Preferably, the oil outlet is communicated with a large cavity in the cavity through a small circular tube.
Preferably, two U-shaped pipes are arranged, the initial positions of the U-shaped pipes are communicated with two large cavities, one U-shaped pipe is arranged at the proximal end of the small cavity, and the other U-shaped pipe is arranged at the distal end of the small cavity.
Preferably, the two ends of the blade are respectively positioned in the cavity, and the cavity is divided into a small cavity and a large cavity.
The beneficial effects are that:
the overflow valve is skillfully and mechanically arranged, and the spring steel is utilized, so that the overflow valve has the advantages of wide pressure range, strong pollution resistance, low manufacturing cost, high cost performance and portability in manual pressure regulation.

FIG. 2 is a schematic view of a portion of a cavity according to the present invention;
in the figure: 1. a rotary piece; 2. a threaded rod; 3. a bolt; 4. a valve body; 5. a cylinder; 6. spring steel; 7. a valve core; 8. an oil inlet; 9. an oil outlet; 10. a small round tube; 11. a blade; 12. a cavity; 1201. a small cavity; 1202. a large cavity; 13. u-shaped tube.
Detailed Description
As shown in the accompanying drawings:
the invention provides a Jiang Zhuaifa overflow valve with wide pressure regulating range and pollution resistance, which comprises a valve body 4, an oil inlet 8 and an oil outlet 9, wherein a rotary piece 1 is arranged at the top of the valve body 4, bolts 3 are arranged on the top surface of the valve body 4, the rotary piece 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 circular tube 10.
Wherein the oil outlet 9 is communicated with a large cavity 1202 in the cavity 12 through a small round tube.
Wherein, two U-shaped pipes 13 are arranged, and the initial positions are communicated with two large cavities, one U-shaped pipe is arranged at the proximal end of the small cavity 1201 and the other U-shaped pipe 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 cavity 12 is divided into a small cavity 1201 and a large cavity 1202.
Working principle:
firstly, the rotary piece 1 is rotated, so that the cylinder 5 is stressed, the spring steel 6 is stressed indirectly, the spring steel 6 finally stresses the blade 11, and the blade can be rotated only when the oil pressure reaches a certain degree, so that the function of the overflow valve is realized. After the rotary piece rotates, oil enters from the oil inlet 8, oil enters the small cavity 1201 due to the small round tube 10 and the communication of the small round tube, then the part of the blade located in the cavity 12 is subjected to the pressure of oil pressure, the end part of the blade is pushed to the large cavity 1202, so that the rotation of the blade is realized, the rotation of the blade drives the valve core 7, then the groove on the valve core 7 rotates to a certain angle, the oil can pass through the groove part quickly, and the oil pressure is reduced, so that the oil pressure cannot exceed a critical point. The invention has simple structure and safe and convenient use.
The foregoing is merely illustrative of the embodiments of the present invention, and the scope of the present invention is not limited thereto, and any changes or substitutions that may be made by those skilled in the art without departing from the spirit and scope of the present invention are intended to be covered by the present invention, and the scope of the present invention is defined by the appended claims.
