Back-moving spring, is mainly used in buffering the motion of oil-out spring base；The back-moving spring of valve element is the important portion of high-speed switch valve
Part, when the coil is de-energized, valve element return to the limit on the left position of valve element with armature by spring-force driven dual, so as to change fluid stream
Logical direction.
Electric control principle of the present invention：
Figure is shown in the regulation in real time of the achievable electric-control system of the present invention.High-speed electromagnetic valve becomes one with electric control gear, can root
Need to change the driving parameter of electric control gear according to system, adjust the running status of high-speed electromagnetic valve, current signal and displacement are passed
The displacement signal of sensor shows that (high-speed electromagnetic valve experimental stage replaces the execution that piston component is connected with frock in oscillograph
Part), the action situation of piston is observed with this, judges whether tolerance stepless regulating system normally runs.
Fluid cooling system of the present invention：
This high-speed electromagnetic valve makes full use of the design of part feature such as housing, valve body, valve element, and cooling oil is designed with interiors of products
Road, makes a small amount of internal leakage fluid that magnetic valve is produced be played during oil-out is flowed to internal heating in heating part cycle down
The effect of temperature, is effectively reduced due to the problems such as the hydraulic performance decline produced by product self-heating, reliability are reduced.Cooling oil
Flow channel footpath is as shown in the figure.
Analyzed at general assembly sealing of the present invention：
This high-speed electromagnetic valve allows the presence of a small amount of internal leakage, but causes energy for internal leakage when avoiding the magnetic valve from powering off is overproof
Amount loss increase, magnetic valve carries out should be noted following three points during overall assembling：
Oil inlet tube joint assembly should ensure that it with being flat seal at valve seat, therefore when installing oil inlet tube joint assembly
Bottom surface and plane contact on valve seat, prevent excessive fluid from being flowed out at this.
Piston component prevents high-voltage oil liquid from being produced during flowing to piston component with being conical surface seal at valve body contact
Raw leakage causes the hydraulic energy loss for promoting piston action, influences the realization of product function.Therefore, ensure when piston component is installed
Taper-face contact is sealed.
Seal receptacle prevents fluid flows out at gap from causing leakage rate overproof, the opposing party with being flat seal at valve body
Face can also influence the action displacement of valve element.To ensure that seal receptacle is installed in place when therefore oil-out pipe joint is installed, and and valve body
Plane contact is sealed.
It is described above, only it is the preferred embodiment of patent of the present invention, not makees any formal to patent of the present invention
Limitation, any without departing from art solutions content of the present invention, the technical spirit according to patent of the present invention is to above example
Any simple modification, equivalent variations and the modification made, in the range of still falling within art solutions of the present invention.
