Mechanical manufacturing adjusting valve

Abstract

The invention belongs to the technical field of valves, and particularly relates to a mechanical manufacturing adjusting valve. The mechanical manufacturing adjusting valve comprises a valve body and a connecting sleeve, the left end of the valve body is connected with a liquid pipe through a fixing sleeve, the upper end of the liquid pipe is connected with the fixing sleeve through a sealing ring, and a rack used for adjusting the tightness of the fixing sleeve is arranged in the fixing sleeve. The fixing sleeve is further provided with a gear used for connecting the rack and the gear, the gear is connected with a connecting disc through a connecting shaft, traditional bolt and nut connection is changed through the arrangement of the fixing sleeve, connection can be easily completed in some narrow spaces, the space requirement for the connecting position is greatly reduced, and through the connection of the rack and the gear, the connecting gap between the fixing sleeve and the liquid pipe is adjusted, the sealing performance of the fixing sleeve and the liquid pipe is enhanced through the arrangement of the sealing ring, the situation that the surface of a valve element is rusted and corroded due to long-time soaking can be prevented through the arrangement of an anti-corrosion coating, the service life of the adjusting valve is indirectly prolonged, and people can use the adjusting valve conveniently.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a mechanically manufactured regulating valve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, by receiving the control signal output by the adjustment control unit, with the help of power operation to change the final control element of process parameters such as medium flow, pressure, temperature, liquid level, etc., the control valve is generally Composed of actuators and valves, regulating valves have a wide range of applications in the field of mechanical manufacturing. [0003] The turntable on the upper end of the original machine-made regulating valve is not easy to disassemble, which is not conducive to the work under some special circumstances. The stressed end is seriously damaged, and the service life is not long. The inside of the valve core is exposed to liquid for a long tim...

AI Technical Summary

Problems solved by technology

[0003] The turntable on the upper end of the original machine-made control valve is not easy to disassemble, which is not conducive to the work under some special circumstances. The stressed end is seriously damaged, and the service life is not long. The inside of the valve core is exposed to liquid for a long time, and it is easy to rust and corrode. The regulating valve and the liquid pipe are connected by nuts. Under some special conditions, the connected The other end face is extremely inconvenient when tightening, reducing work efficiency
