Abstract
The invention discloses a processing technique for a valve core of a single-seat regulating valve. The processing technique for the valve core of the single-seat regulating valve is characterized by including the steps of blanking, primary lathing, secondary lathing, third lathing, drill processing, inspecting, marking the qualified products, cleaning and storing. The processing technique for the valve core of the single-seat regulating valve is capable of obtaining the regulating valve core with high precision; because two ends of the regulating valve core are processed individually, the service life of the regulating valve core is prolonged greatly, and the reliability of the flat single-seat regulating valve is improved.
Description
Technical field
The invention belongs to control valve technical field, specifically, relate in particular to a kind of single-seat adjusting valve spool 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 that adjuster is exported, 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 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.
Regulation valve core is a vitals of single-seat adjusting valve, therefore all can have larger impact the crudy of regulation valve core service life on single-seat adjusting valve etc., so design a kind of technique that can put forward regulation valve core crudy, necessitates.
Summary of the invention
The object of the invention is to provide a kind of single-seat adjusting valve spool processing technology that can improve regulation valve core high life.
For achieving the above object, the invention provides a kind of single-seat adjusting valve spool processing technology, it is characterized in that comprising the steps:
Step 1, blanking: adopt round steel to carry out blanking;
Step 2, Vehicle Processing for the first time: blank one end that step 1 is obtained is fixed on lathe according to not stiff end of figure paper conversion;
Step 3, Vehicle Processing for the second time: other one end of product that step 2 is obtained is fixed on lathe according to not stiff end of figure paper conversion;
Step 4, Vehicle Processing for the third time: the product that step 3 is obtained oppositely adopts soft three-jaw folder cylindrical to be fixed on lathe according to figure paper conversion;
Step 5, drilling machine processing: the product that step 4 is obtained adopts V-block location, is pressed abd fixed on drilling machine according to figure paper conversion;
Step 6, be up to the standards, clean after marking warehouse-in.
The present invention adopts above step to carry out, and can obtain the regulation valve core that precision is high, because two end faces of regulation valve core are processed respectively, thus the service life of greatly having improved regulation valve core, thus the reliability of flat single-seat adjusting valve increased.
Step 2 Vehicle Processing step is for the first time such:
1) face work is to flat;
2) rough turn cylindrical, stays 0.5mm surplus.
Step 3 Vehicle Processing step is for the second time such:
1) face work is flat;
2) turning, end face and end face are to size;
3) auger shell line path;
4) reaming, made allowance 0.2mm;
5) car endoporus is to size;
6) chamfering, cutting thread;
7) chamfering, deburring.
Step 4 Vehicle Processing step is for the third time such:
1) face work is flat, guarantees overall length;
2) rough turn cylindrical, made allowance 1mm;
3) rough turn valve line and curved surface made allowance;
4) fine turning outer circle is to size;
5) finish turning valve line and curved surface are to size;
6) chamfering, deburring.
Step 5 drilling machine Vehicle Processing step is such:
1) draw hole site line;
2) boring;
3) deburring.
Adopt above step, one end of first converted products, then must arrive the spool that one end processes, thereby be easy to clamping, so guaranteed crudy.
The invention has the beneficial effects as follows: can obtain the regulation valve core that precision is high, because two ends of regulation valve core are processed respectively, thus the service life of greatly having improved regulation valve core, thus the reliability of flat single-seat adjusting valve increased.
