Pressure valve

Abstract

The invention provides a pressure valve and belongs to the technical field of lathe machining. The technical problems that an existing control valve machining process is complex, the production efficiency is low, and the locating precision is poor are solved. The pressure valve comprises a fixed platform, an annular guide rail and a machining unit are arranged on the fixed platform, and a first mounting unit and a second mounting unit are arranged on the annular guide rail. The first mounting unit and the second mounting unit are provided with a plurality of control valves correspondingly, andeach control valve is provided with six faces, wherein three adjacent faces form a first set of machining faces, and the other three faces form a second set of machining faces. The first mounting unit and the second mounting unit revolute on the annular guide rail, and the first sets of machining faces of the control valves in the first mounting unit and the second sets of machining faces of thecontrol valves in the second mounting unit are machined by the machining unit. The pressure valve is high in production efficiency, simple in process, accurate in positioning and good overall precision consistency of the machined control valves.

Description

technical field [0001] The invention belongs to the technical field of lathe processing, and relates to a processing device, in particular to a pressure valve. Background technique [0002] Proportional pressure control valve is a kind of self-operated regulating valve, which belongs to one of the control valve series. It is used in various machinery with pressure system. Its main function is to adjust the pressure, flow, temperature and other parameters of the medium. The final control element in the road, through the proportional adjustment of the medium pressure, and then realizes the proportional control of the output force or output torque, which can greatly simplify the debugging of the system and stabilize the working state of the pump. It is suitable for air, water , steam, various corrosive media, mud, oil and other media. [0003] There is a commonly used proportional pressure control valve in injection machines.

AI Technical Summary

Problems solved by technology

[0003] There is a commonly used proportional pressure control valve in injection machines. The shape of this proportional pressure control valve is a cuboid block with six faces, and each face has a number of holes of different sizes. It is characterized by a complex structure. , the processing accuracy is high, so the processing equipment of the proportional pressure control valve must also have high precision requirements. However, at present, the processing technology of the processing equipment of the proportional pressure control valve for injection machines is relatively scattered. A variety of processing equipment is required, such as CNC lathes, vertical machining centers, radial drilling machines, bench drills and other processing equipment. Among them, CNC lathes need to be clamped repeatedly three times, machining centers need to be clamped twice, and bench drills need to use Multiple pairs of drilling jigs, so there are the following problems: 1. Since the six faces of a control valve need to be completed on a variety of processing equipment, and the positioning accuracy of each processing equipment is different, so the processing of each face of the control valve There is a difference in precision, which leads to poor consistency in the overall machining accuracy of the control valve, and the final formed control valve cannot be matched with the machine for practicality; 2. A control valve is processed by multiple processing equipment, the turnover during processing is too frequent, and the processing technology is relatively complicated , the overall processing time of the control valve is lengthened invisibly, the production efficiency is low, and the labor intensity is increased; 3. It needs to be equipped with a variety of processing equipment, so the production cost is high and the energy consumption is large
