Technical Field
The invention relates to the technical field of overflow valves, in particular to a worm-gear overflow valve with wide pressure regulating range and strong pollution resistance.
Background
Relief valves are critical safety applications for pressure lines and pressure vessels, but most of the current relief valves are limited in the range of applied pressure and cannot be widely used. Even if the pressure range is wide, the cost is expensive, the popularization and the use are not facilitated, the overflow valve is also faced with dust, rust dirt and other dirt to invade the safety valve and the discharge pipeline, the pollution resistance is not high, and the pressure regulation is sometimes inconvenient.
Disclosure of Invention
The invention aims to solve the technical problems that the existing overflow valve has a wide pressure range, strong pollution resistance and convenient pressure regulation.
The invention discloses a worm and gear overflow valve with wide pressure regulating range and strong pollution resistance, which is realized by the following specific technical means:
the utility model provides a wide antipollution ability worm gear formula overflow valve of pressure regulating scope, includes casing, oil inlet, oil-out, install the knob on the casing, and install the bolt at casing top and bottom, knob and worm, worm wheel is installed to the worm side, the worm wheel centre 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 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.
The beneficial effects are that:
the overflow valve is skillfully and mechanically arranged, the oil pressure is utilized to drive the blades to rotate, and the worm gear is utilized to adjust the pressure, so that the overflow valve has wide pressure range, strong pollution resistance, low cost and high cost performance, and can be manually and conveniently adjusted.

Detailed Description
As shown in the accompanying drawings:
the invention provides a worm and gear overflow valve with 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 arranged on the shell 1, bolts 5 are arranged at the top and the bottom of the shell 1, the knob 2 and a worm 3 are arranged at the side edge of the worm 3, a worm wheel 4 is arranged at the center of the worm wheel 4, a spring piece 401 is arranged at the center of the spring piece 401 and is connected with a valve core 6, a blade 9 is arranged at the bottom of the valve core 6, two ends of the blade 9 are positioned in a cavity 11, the cavity 11 is divided into a small cavity 13 and a large cavity 12 by the blade 9, the two cavities 11 are arranged and are connected through a U-shaped pipe 14, and the oil inlet 7 is connected with the cavity 11 through a round 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 circular tube 8.
Wherein the oil outlet 10 is communicated with a large cavity 12 in the cavity 11 through a small round tube.
Wherein, two U-shaped pipes 14 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 13, and the other U-shaped pipe is arranged at the distal end of the small cavity 13.
Working principle:
firstly, the knob is turned, the worm wheel stress is regulated, so that the spring piece is stressed, the valve core is stressed by the spring piece, and finally, the valve core is stressed by the blade, so that the blade can be rotated only when the oil pressure reaches a certain degree, and the function of the overflow valve is realized. After the knob rotates, oil enters from the oil inlet, and because of the small round tube and the communication of the small round tube, the oil enters into the small cavity, then the part of the blade positioned in the cavity is subjected to the pressure of the oil pressure, the end part of the blade is pushed to the large cavity, so that the rotation of the blade is realized, the rotation of the blade drives the rotation of the valve core, then the groove on the valve core is rotated to a certain angle, the oil can pass through the groove part quickly, the oil pressure is reduced, and the oil pressure can not 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.
