Abstract
The invention discloses a processing technology of a guide ring of a single-seat adjusting valve. The processing technology is characterized by comprising the following steps of forging, carrying out thermal treatment, turning for the first time, turning for the second time, processing a screw thread, marking after passing the inspection, cleaning and putting the guide ring into a storage. By adopting the processing technology, the high-precision guide ring of the adjusting valve can be obtained, two end faces of the guide ring of the adjusting valve are respectively processed, so that the service life of the guide ring of the adjusting valve is greatly prolonged, thus the reliability of the flat single-seat adjusting valve is increased.
Description
Technical field
The invention belongs to control valve technical field, specifically, relate in particular to a kind of single-seat adjusting valve guide ring processing technology.
Background technology
Single-seat adjusting valve is equipped with by regulation valve body the industry spot execution instrument that different YEs forms, it accepts 4-20mA or the pulse signal of adjuster output, carry out closed-loop control, realization is to flow, pressure, temperature, the isoparametric automatic control of liquid level, and can select intelligent electric executer, realize Digital Transmission with DCS, PLC etc., form more intelligent control system.The supply voltage of electric control valve has two kinds of 220V and 380V, the discharge characteristic of electric control valve have equal percentage, linearity, fast etc. three kinds.
Single-seat adjusting valve divides single seat diaphragm valve and single seat piston type regulating valve, it is to take compressed air as power source, take diaphragm type or piston type cylinder as actuator, and remove to drive valve by means of annexes such as electropneumatic valve positioner, converter, magnetic valve, guarantor position valves, realize switching value or proportion expression and regulate, the control signal that receives industrial automation control system completes the various technological parameters such as the flow of adjustable pipe track media, pressure, temperature.The feature of pneumatic control valve controls simply exactly, react fast and essential safety, do not need to take in addition explosion precaution again.The cost of pneumatic control valve is also low with respect to electric control valve, and in fields such as chemical industry, petrochemical industry, pneumatic control valve has the incomparable advantage of electric control valve.
Control valve guide ring is a vitals of single-seat adjusting valve, therefore the crudy of control valve guide ring, on service life of single-seat adjusting valve etc. all having larger impact, necessitates so design a kind of technique that can put forward control valve guide ring crudy.
Summary of the invention
The object of the invention is to provide a kind of single-seat adjusting valve guide ring processing technology that can improve control valve guide ring high life.
For achieving the above object, the invention provides a kind of single-seat adjusting valve guide ring processing technology, it is characterized in that comprising the steps:
Step 1, forging: will after blank heating, in mould, forge, obtain closing the blank of symbol size;
Step 2, heat treatment: the blank that step 1 is obtained carries out stress relief annealing processing;
Step 3, Vehicle Processing for the first time: blank one end that step 2 is obtained is fixed on lathe according to figure paper conversion stiff end not;
Step 4, Vehicle Processing for the second time, other one end of product that step 3 is obtained is fixed on lathe according to figure paper conversion stiff end not;
Step 5, machining screw, the product that step 4 is obtained is pressed from both sides and is fixed on drilling machine by three-jaw, first draws two screw center lines, and then auger shell line path, drills through, last chamfering, tapping;
Step 6, marking after the assay was approved, then clean warehouse-in.
The present invention adopts above step to carry out, and can access the control valve guide ring that precision is high, because two end faces of control valve guide ring are processed respectively, thus the service life of greatly having improved control valve guide ring, thus the reliability of flat single-seat adjusting valve increased.
Step 3 Vehicle Processing step is for the first time such:
1) face work is to flat;
2) turning and end face are to size;
3) chamfering, then deburring.
Step 4 Vehicle Processing step is for the second time such:
1) face work is to size;
2) turning is to size;
3) ride rank are to size;
4) boring, made allowance 2mm;
5) car endoporus is to size;
6) the interior stepped hole of car is to size;
7) chamfering, then deburring.
Adopt above step, one end of first converted products, then must arrive the guide ring that one end processes, thereby is easy to clamping, so guaranteed crudy.
The invention has the beneficial effects as follows: can access the control valve guide ring that precision is high, because two end faces of control valve guide ring are processed respectively, thus the service life of greatly having improved control valve guide ring, thus the reliability of flat single-seat adjusting valve increased.
