Detailed description of the invention
nullDetermine ferrum 2 for electromagnetic pure iron，Plunger tube 4 is rustless steel，Determine ferrum 2 and plunger tube 4 laser welding，Plunger tube 4 be mounted to valve body 18 internal and with valve body 18 laser welding，Valve body 18 presses with valve seat 7 fixing connection，Valve body 18 lower surface is connected with valve seat 7 upper surface，Valve body 18 inner circle and valve seat 7 cylindrical are by O RunddichtringO 2 11 radial seal，Valve body crimp 14 is connected with the face of pressing of valve seat 7，Dynamic ferrum 5 lower end is assemblied in valve body 18，Dynamic ferrum 5 upper end is 45 degree of circular cone convex surfaces，Determine ferrum 2 to be positioned at above dynamic ferrum 5，Determining ferrum 2 lower end is 45 degree of circular cone concave surfaces，Axial step through hole 17 is had in the middle of dynamic ferrum 5，There is T-slot 19 lower end，Dynamic ferrum 5 and plunger tube 4 radial clearance fit，Spring 1 one end contacts with determining ferrum 2 circular cone concave surface，The other end contacts with step through-hole 17 shoulder，Valve seat 7 lower end and base 8 radial clearance fit，And by O RunddichtringO 1 radial seal，Piston 6 and valve seat 7 endoporus radial clearance fit，And by combined seal ring 10 and valve seat 7 endoporus radial seal，C chamber 25 is formed between valve seat 7 and valve body 18，Piston 6 and valve seat 7 form A chamber 23，There is annular groove 20 piston 6 upper end，Annular groove 20 and dynamic ferrum T-slot 19 matched in clearance，Valve seat 7 is stretched out in piston 6 lower end，Piston 6 bottom is the conical surface 21，16 times seamed edges of valve seat 7 axially extending bore 22 are right angle，Valve seat 7 axially extending bore 16 is smaller in size than the maximum gauge of piston 6 conical surface 21，Lower seamed edge 22 is connected with the conical surface 21，Piston 6 is internal axially extending bore 16，Axially extending bore 16 lower end communicates with B chamber 24，Upper end is communicated with D chamber 26 by the step through-hole 17 of dynamic ferrum 5，Piston 6 is internal has radial direction through hole 2 15 by through with axially extending bore 16 for C chamber 25，Valve seat 7 bottom radial direction through hole 1 communicates with A chamber 23.
Assemble sequence: first valve seat 7 is assembled with piston 6, again the T-slot 19 of the annular groove 20 of piston 6 with dynamic ferrum 5 is attached, after finally dynamic ferrum 5 being docked with plunger tube 4 on the valve body 18 welded, carry out pressing of valve body 18 and valve seat 7, electromagnetic valve body 18 and base 8 press for interference and are connected, having annular groove 13 at valve body 18 and base engagement, valve body 18 material unnecessary when pressing is clamp-oned in annular groove, increases riveting intensity.Valve body 18 and valve seat 7 press before for valve body straight flange 14 ', thick about the 1.5mm of valve body straight flange 14 ', exceed valve seat 7 and press face 2 ~ 3mm, valve seat 7 face of pressing is 45 degree of conical surfaces.Press rear valve body crimp 14 and valve seat 7 presses face reliable contacts, and this kind of riveting process riveting precision is high, bears pressure big, simple in construction, it is achieved that valve body 18 is reliably connected with valve seat 7.
Determining ferrum 2 one end is 45 degree of circular cone concave surfaces, and dynamic ferrum 5 one end is 45 degree of circular cone convex surfaces, forms conical surface electromagnetism air gap, can increase electromagnetic force under conditions of equal number of ampere turns.During it addition, dynamic ferrum 5 assembles with valve body 18, circular cone convex surface is beneficial to guide.
Being equal diameter at piston 6 and valve seat 7 endoporus radial clearance fit, fit clearance is the least, with combined seal ring 10 and valve seat 7 endoporus radial seal, is isolated with C chamber in A chamber, it is ensured that on the premise of sealing, piston 6 can axially-movable freely, reduce frictional resistance.
The principle of the present invention:
When liquid is flowed into by A chamber, when electromagnetic valve is not powered on, liquid flows into B chamber via electromagnetic valve valve port, flows to, through piston inner hole and dynamic ferrum endoporus, the axial hydraulic dynamic balance that C chamber and D chamber, piston and dynamic ferrum are subject to simultaneously, and piston is positioned at lower dead center under the action of the spring.
When liquid is flowed into by A chamber, when electromagnetic valve is switched to "on" position by the state of being not powered on, dynamic ferrum drives under the effect of electromagnetic force and moves in piston overpowers spring resistance and frictional force, and when the base cone face of piston contacts with the endoporus seamed edge of valve seat, A chamber isolates with B chamber.Supercharging is continued in A chamber, due to piston equal diameters at sealing valve port and at O RunddichtringO, the A chamber axial pressure balance to piston, will not be opened by valve port when the pressure in A chamber is higher than B chamber.Achieve the isolation in A chamber and B chamber.
When liquid is flowed into by A chamber, electromagnetic valve is switched to by energising when being not powered on, and piston moves down under the action of the spring, and valve port is opened.
When liquid is flowed into by B chamber, when electromagnetic valve is not powered on, liquid flows into A chamber via electromagnetic valve valve port, flows to, through piston inner hole and dynamic ferrum endoporus, the axial hydraulic dynamic balance that C chamber and D chamber, piston and dynamic ferrum are subject to simultaneously, and piston is positioned at lower dead center under the action of the spring.
When liquid is flowed into by B chamber, when electromagnetic valve is switched to energising by the state of being not powered on, dynamic ferrum drives under the effect of electromagnetic force and moves in piston overpowers spring resistance and frictional force, and when the base cone face of piston contacts with the endoporus seamed edge of valve seat, B chamber isolates with A chamber.Supercharging is continued in B chamber, and liquid flows to C chamber and D chamber through piston inner hole and dynamic ferrum endoporus, due to piston equal diameters, B chamber and C chamber axial pressure balance to piston at sealing valve port and at O RunddichtringO.When B cavity pressure continues to raise, when the pressure in B chamber is higher than A chamber, valve port will not be opened.Achieve the isolation in B chamber and A chamber.
When liquid is flowed into by B chamber, electromagnetic valve is switched to by energising when being not powered on, and piston moves down under the action of the spring, and valve port is opened.
