Abstract
The invention discloses a machining process of a balance cage type regulating valve locking nut. The machining process is characterized by comprising the steps of discharging, turning, drilling, thread turning, spanner milling, galvanizing, checking and the like. By the adoption of the machining process, the regulating valve locking nut having high accuracy can be obtained. As galvanizing can be conducted on the machining surface of the regulating valve locking nut, service life of the regulating valve locking nut is greatly prolonged.
Description
Technical field
The invention belongs to control valve technical field, specifically, relate in particular to a kind of balance cage type regulating valve locking nut processing technology.
Background technology
Cage type regulating valve is pressure balance type control valve, and trim adopts the pilot-operated type spool of cage guiding, and it mainly utilizes the pressure of fluid to realize spool quick acting, and operating physical force is little.In addition, seal style adopts single seat sealing, and rating curve precision is high, meets IEC534-1 standard.Control valve dynamic stability is good, noise is low, anti-cavitation, the High Pressure Difference fluid of the various temperature of suitable control.Many springs of adapted diaphragm actuator or electric operator, its compact conformation, High power output.
Locking nut is a vitals of cage type regulating valve, so the crudy of locking nut is on all having larger impact service life of cage type regulating valve etc., so design a kind of technique that can improve locking nut crudy, necessitates.
Summary of the invention
The object of the invention is to provide a kind of balance cage type regulating valve locking nut processing technology that can improve control valve locking nut high life.
For achieving the above object, the invention provides a kind of balance cage type regulating valve locking nut processing technology, it is characterized in that comprising the steps:
Step 1, blanking: bar is placed into the blank material that sawing machine closes symbol dimensional requirement up and down;
Step 2, turning processing: the blank material that step 1 is obtained face work and turning on lathe;
Step 3, boring: the product that step 2 is obtained is holed, should stay the surplus of 2mm, then according to product size, cuts material, thereby obtain meeting the product of gauge;
Step 4, cutting thread: the product that step 3 is obtained is according to drawing requirement Internal Threading;
Step 5, milling spanner: the product that as requested step 4 obtained adopts machine vice to step up clamping to milling spanner on milling machine, is milling product outer fix;
Step 6, zinc-plated: product that step 5 is obtained is zinc-plated carries out antirust processing;
Step 7, check: put in storage after the assay was approved.
The present invention adopts above step to carry out, can access the control valve locking nut that precision is high, due to zinc-plated on the machined surface at control valve locking nut, thus the service life of greatly having improved control valve locking nut, thus increased the reliability of balance cage type regulating valve.
After step 4 cutting thread, also need product outside to meet the chamfering of size.Thereby can be good at coordinating with miscellaneous part,
The invention has the beneficial effects as follows: employing of the present invention can access the control valve locking nut that precision is high, due to zinc-plated on the machined surface at control valve locking nut, thus the service life of greatly having improved control valve locking nut.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention;
Fig. 2 is the structural representation of control valve locking nut.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
