Abstract
The utility model discloses a balancing reversing valve for an upper roller. The reversing valve comprises electromagnetic coil casings, wherein armatures are arranged in the electromagnetic coil casings; a through hole is formed in one side of the end part, where one armature is located, of each electromagnetic coil casing, and one hand-operated device is arranged at the through hole. According to the balancing reversing valve, the hand device is added, if pressure is not established, all that is required is to manually push the armatures and a valve element with the hand-operated device, then the valve can work normally, and the valve is not required to be changed, so that the service life of the balancing reversing valve for the upper roller is prolonged, and the valve changing time is shortened.
Description
Technical field
The utility model relates to a kind of selector valve, specifically, relates to a kind of top roll balance selector valve.
Background technique
Compact type is easily changed the top roll balance selector valve (two position and four-way reversing valves) of formula milling train (Compact Cartridge Stands, CCS) milling train, after roll change, sometimes because the slight jam of spool causes foundation, does not play pressure, needs to change balance selector valve.
As shown in Figure 1, be the schematic diagram of top roll balance selector valve in prior art; As shown in Figure 2, be the structural drawing of top roll balance selector valve in prior art.The structure of top roll balance selector valve comprises: valve body 1, electromagnetic coil 2, spool 3, armature 4, spring 5 and electromagnetic coil shell 6; Valve body 1 is hollow structure, at two ends, be provided with electromagnetic coil shell 6, valve body 1 and electromagnetic coil shell 6 communicate, electromagnetic coil shell 6 inside are provided with electromagnetic coil 2 and armature 4, the end of two armature 4 is positioned at spool 3 two ends, spring 5 is equipped with in two ends at spool 3, and spring 5 is inner and withstand between valve body 1 and electromagnetic coil shell 6 at valve body 1.
After a end electromagnetic coil 2 dead electricity, armature 4 loses thrust, and the reset of spool 3 can only lean on the spring 5 of b end to promote, as larger in spool 3 resistances, and spring 5 does not just promote spool 3, does not realize commutation.
Model utility content
The technical problem that the utility model solves is to provide a kind of top roll balance selector valve, has increased the working life of top roll balance selector valve, has reduced and has changed the valve time.
Technological scheme is as follows:
A top roll balance selector valve, comprises electromagnetic coil shell, and described electromagnetic coil enclosure is provided with armature, and end one side that described electromagnetic coil shell is positioned at described armature has through hole, and described through hole is provided with manual operating device.
Further: an end of described manual operating device is fixed on described armature, and stretch out outside described through hole another end.
Compared with prior art, the utility model technique effect comprises:
The utility model installs additional after manual operating device, as can not set up pressure and only need utilize manual operating device manually to disclose armature and spool will normally be worked, and without changing valve, thereby has increased working life of top roll balance selector valve, has reduced and has changed the valve time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of top roll balance selector valve in prior art;
Fig. 2 is the structural drawing of top roll balance selector valve in prior art;
Fig. 3 is the schematic diagram of top roll balance selector valve in the utility model;
Fig. 4 is the structural drawing of top roll balance selector valve in the utility model.
Embodiment
Below with reference to accompanying drawing and preferred embodiment, technical solutions of the utility model are elaborated.
As shown in Figure 3, be the schematic diagram of top roll balance selector valve in the utility model; As shown in Figure 4, be the structural drawing of top roll balance selector valve in the utility model.
In the utility model, top roll balance selector valve has increased manual operating device 7.On electromagnetic coil shell 6, be positioned at armature 4 end one sides and open a through hole, manual operating device 7 is arranged on this through hole; One of two end of manual operating device 7 are fixed on armature 4, and stretch out outside through hole another end.
As can not set up pressure, and only needing to promote manual operating device 7, manual operating device 7 promotion armature 4 and spool 3 move and just can recover normal, without changing valve.
After electromagnetic coil 2 dead electricity of a end, spool 3 resets except leaning on the spring 5 of b end to promote, and newly-increased manual operating device 7 also can promote spool 3, increases the Driving force of spool 3, makes its commutation.
