Novel screw thread cartridge formula cone valve overflow valve

Technical Field

The utility model relates to the technical field of hydraulic valve elements, in particular to a novel threaded plug-in type cone valve overflow valve.

Background

The valve is a device installed in a pipeline for controlling the flow of liquid, is a control part in a fluid conveying system, and has the functions of stopping, adjusting, guiding, preventing reverse flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves can be classified into cutoff type, non-return type, safety type, regulation type and shunt type according to functions and purposes, can be classified into vacuum valves, low-pressure valves, medium-pressure valves, high-pressure valves and ultrahigh-pressure valves according to nominal pressure, can be classified into ultralow-temperature valves, low-temperature valves, normal-temperature valves, medium-temperature valves and high-temperature valves according to working temperature, and can be classified into automatic valves, power-driven valves and manual valves according to driving modes.

The existing plate-type overflow valve has the disadvantages of large integral volume, poor sealing property, overlarge leakage, poor sensitivity of pressure adjustment, troublesome disassembly during installation and maintenance, overhigh manufacturing cost and the like, and greatly increases the production cost of a factory.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

As shown in fig. 1, a novel threaded plug-in type cone valve overflow valve comprises an overflow valve body 1, an oil inlet 6 and an oil outlet 7 are formed in the body, a valve core 5 is arranged in the body, a spring 8 is connected to the valve core 5, an adjusting screw 3 is connected to the spring 8, the adjusting screw 3 extends out of the body from the inside of the body, the spring 8 is compressed by rotating the adjusting screw 3 to move in the overflow valve body 1, the spring 8 compresses the valve core 5 to increase the pressure of the valve core 5, and the adjusting screw 3 is rotated to move out of the overflow valve body 1 to reduce the pressure of the valve core 5, so that the adjustment is convenient. Oil inlet 6 department is provided with first sealing washer 9, and the other first retaining ring 10 that is provided with of first sealing washer 9 is provided with external screw thread 17 on the overflow valve body 1, and the other second sealing washer 11 that is provided with of external screw thread 17 sets up first sealing washer 9 and first retaining ring 10, avoids fluid exosmosis, and external screw thread 17 and outside cylinder body threaded connection, easy dismounting set up second sealing washer 11 and prevent that fluid exosmoses outside the cylinder body, increase the leakproofness. The overflow valve body 1 is provided with a threaded sleeve 2, the threaded sleeve 2 is provided with a third sealing ring 12, the spring 8 and the adjusting screw rod 3 are connected with the threaded sleeve 2, the threaded sleeve 2 is arranged to facilitate disassembly and assembly and maintenance, the threaded sleeve 2 is provided with a nut 4, the nut 4 is in threaded connection with the adjusting screw rod 3, and after the adjusting screw rod 3 is adjusted, the nut 4 is locked, so that the pressure influence caused by the looseness of the adjusting screw rod 3 is avoided.
