Embodiment
In conjunction with following examples the utility model is described further.
embodiment 1.
A kind of integral type Proportional valve, as shown in Figure 1, comprise electrical assembly 2, ratio coil 3, armature plunger 4, spool 5, valve seat 6, P pipe 8, T pipe 7, inner chamber 9 and oily gateway 13, armature plunger 4, spool 5 and valve seat 6 are arranged at inner chamber 9;
The control end of electrical assembly 2 is connected with an end of ratio coil 3; The other end of ratio coil 3 is connected with an end of armature plunger 4; The other end of armature plunger 4 is connected with an end of spool 5; One end of the other end of spool 5 and P pipe 8 is relative, and inner chamber 9 is provided with outlet, and an end of T pipe 7 is communicated with outlet.
A kind of integral type Proportional valve of the utility model; Comprise electrical assembly 2, ratio coil 3, armature plunger 4, spool 5, valve seat 6, P pipe 8, T pipe 7 and oily gateway 13, compared with prior art, the utility model level of integration is high; Independent transducer and amplifier link have been omitted in the control; Control principle be " dcs (distributed control system) signal---Proportional valve, control principle is simple, fault is prone to look into; can make big roller squeezer working stability, protection felt and squeeze roller are not fragile when guaranteeing the quality of finished paper.
The working principle of the utility model is following:
The utility model is used for restriction system pressure, starts through band centering screw thread and detachable coil, and the inner chamber 9 of coil is communicated with T pipe 7, and fills hydraulic oil, can regulate the system pressure that will limit through the electrical control value.When wanting regulating system pressure, should controlling value be provided to electrical assembly 2, according to this controlling value; Electrical assembly 2 is applied to ratio coil 3 with electric current; Ratio coil 3 is a mechanical force with current conversion, and mechanical force affacts spool 5 through armature plunger 4, and spool 5 is forced on the valve seat 6; Connected relation between P pipe 8 and the T pipe 7 is destroyed, and isolates each other.When the hydraulic coupling on acting on spool 5 equaled magnetic force, armature plunger 4 was regulated the pressure of setting through mentioning spool 5 away from valve seat 6, thereby P pipe 8 and T pipe 7 are communicated with, and hydraulic oil flows to T pipe 7 from P pipe 8.If controlling value is zero, control electrical assembly 2 only applies minimum control electric current in ratio coil 3, thereby produces pressure minimum.
A kind of integral type Proportional valve, as shown in Figure 2, other structure of present embodiment is identical with embodiment 1, and difference is: valve seat 6 also is provided with another outlet, and another outlet is communicated with an end of Y pipe 10.The Y pipe 10 that is provided with, the hydraulic coupling on acting on spool 5 can help emptying during greater than magnetic force better.
The other end of Y pipe 10 is communicated with Unloading Device 14.Utilize Unloading Device 14 to carry out charge of oil.
Main shell 1 corresponding oily gateway 13 is provided with opening.
A kind of integral type Proportional valve, as shown in Figure 3, other structure of present embodiment is identical with embodiment 1, and difference is: electrical assembly 2 is arranged at main shell 1 outside.Convenient for maintaining.
Assembly plug 11 is positioned at shell 12 outsides.Being arranged at shell 12 outside more convenient with outside power supplys is connected with controlling value voltage.
