Even if the pressure range is wide, the manufacturing cost is expensive, the popularization and the use are not facilitated, and the overflow valve is also not high in pollution resistance when dirt such as dust and rust dirt enters a safety valve and a discharge pipeline, and is inconvenient to regulate pressure sometimes.
Disclosure of Invention
The invention aims to solve the technical problems that the existing overflow valve has wide pressure range, strong pollution resistance and convenient pressure regulation.
The invention relates to a worm and gear type overflow valve with wide pressure regulating range and strong pollution resistance, which is achieved by the following specific technical means:
the utility model provides a wide antipollution ability strong worm and gear formula overflow valve of pressure regulating range, includes casing, oil inlet, oil-out, install the knob on the casing, and the bolt is installed to casing top and bottom, knob and worm, the worm wheel is installed to the worm side, the worm wheel positive center is equipped with the spring leaf, the spring leaf is connected with the case, the blade is installed to the case bottom, the blade both ends are located the cavity, divide into little cavity and big cavity by the blade in the cavity, the cavity is equipped with two, through U type union coupling, the oil inlet passes through the pipe and is connected with the cavity.
Preferably, the valve core is provided with a groove.
Preferably, the oil inlet is communicated with the 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 round pipe.
Preferably, the U-shaped tubes are provided in two, and the initial position is to connect two large cavities, wherein one U-shaped tube is at the proximal end of the small cavity and the other U-shaped tube is at the distal end of the small cavity.
Has the advantages that:
the overflow valve is skillfully and mechanically arranged, the oil pressure is used for driving the blades to rotate, and the worm and gear are used for adjusting the pressure, so that the overflow valve has the advantages of wide applicable pressure range, strong pollution resistance, low manufacturing cost, high cost performance, manual pressure adjustment and portability.

Detailed Description
As shown in the attached drawings:
the invention provides a worm and gear type overflow valve with a wide pressure regulating range and strong pollution resistance, which comprises a shell 1, an oil inlet 7 and an oil outlet 10, wherein a knob 2 is installed on the shell 1, bolts 5 are installed at the top and the bottom of the shell 1, the knob 2 and a worm 3 are installed, a worm wheel 4 is installed on the side edge of the worm 3, a spring leaf 401 is arranged at the center of the worm wheel 4, the spring leaf 401 is connected with a valve core 6, a blade 9 is installed at the bottom of the valve core 6, two ends of the blade 9 are located in a cavity 11, the cavity 11 is divided into a small cavity 13 and a large cavity 12 by the blade 9, two cavities 11 are arranged and connected through a U-shaped pipe 14, and the oil inlet 7 is connected with the cavity 11 through a circular pipe 8.
Wherein, the valve core 6 is provided with a groove.
Wherein, the oil inlet 7 is communicated with a small cavity 13 in the cavity 11 through a small round pipe 8.
Wherein, the oil outlet 10 is communicated with a large cavity 12 in the cavity 11 through a small round pipe.
Two U-shaped tubes 14 are provided, and the initial position is to connect two large cavities, wherein one U-shaped tube is at the proximal end of the small cavity 13, and the other U-shaped tube is at the distal end of the small cavity 13.
The working principle is as follows:
at first, the knob is rotated to adjust the stress of the worm wheel, so that the spring piece is stressed, the valve core is stressed, and the valve core finally enables the blade to be stressed, so that the blade can only rotate when the oil pressure reaches a certain degree, and the function of the overflow valve is further realized. The knob is rotatory back, and oil gets into from the oil inlet, because little pipe and its intercommunication, oil gets into little cavity, then that part that the blade is located the cavity receives the pressure of oil pressure, pushes away blade tip toward big cavity to realize the rotation of blade, the rotation of blade drives the rotation of case, then makes the recess on the case rotate certain angle, and oil can pass through the groove part fast, thereby reduces the oil pressure, makes 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 embodiments 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 conceived by the inventive idea 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.
