At closed channel.Under normal operation, normal opened type two-position valve 70 is in normal open state, this normal opened type when specified conditions occur
Two-position valve 70 is in closed channel state.
In conjunction with Fig. 3, returning liquid valve group and include normal opened type two-position valve 70 and choke valve 50, normal opened type two-position valve 70 includes valve body
71, accommodate spool 72 in the spool chamber of valve body 71 711, spool chamber 711 is also connected with connection chamber 73, connect chamber 73 respectively with hydraulic pressure
The hole for back flow of motor 40 connects with liquid back pipe road 42, offers throttle orifice 721 in spool 72, and throttle orifice 721 axially passes through along spool 72
The logical admission chamber 51 arranged and be respectively communicated with spool chamber 711 and choke valve 50.Normal opened type two-position valve 70 and choke valve 50 are combined
It is integrated interconnection system structure, space can be saved.
Described spool chamber 711 includes the step-like vestibule of size diameter section, and described spool 72 is for kiss with spool chamber 711
The step-like spool closed, described connection chamber 73 connects with the reduced diameter section vestibule of spool chamber 711, described spool chamber 711
Major diameter end face place chamber connects with the admission chamber 51 of choke valve 50, and sheathed spring 74 on spool 72, spring 74 provides elastic force
Trend spool 72 moves to connection chamber 73 and spool chamber 711 connected state.
Choke valve 50 includes choke valve valve body 53 and regulation spool 54, and choke valve valve body 53 includes admission chamber 51 and goes out sap cavity
55, admission chamber 51 and go out to have intercommunicating pore 56 between sap cavity 55, liquid outlet 52 connects with going out sap cavity 55, admission chamber 51 and described valve
The major diameter chamber end connection of core cavity 711, the rod end of regulation spool 54 is positioned at sap cavity 55 and intercommunicating pore 56 transition boundary.
Described choke valve 50 arranges two corresponding to the cooling extinguishing arc pipeline 43 arranging two-way, and normal opened type two-position valve 70 is right
Two should be arranged in choke valve 50.Corresponding to two-way cooling extinguishing arc pipeline 43, two groups of choke valves 50 and normal opened type two-position valve are set
70, it is ensured that all can close normal opened type two-position valve in time when stopping state occurs in any road cooling extinguishing arc pipeline 43
70。
Below in conjunction with work process, operation principle of the present utility model is described.
When normally working, in conjunction with Fig. 2,3, operation water influent pipeline 41 on switch valve 44, pressure emulsified liquid is through switch valve
44 enter hydraulic motor 40, and band saw blades 30 revolution of annular winding on hydraulic motor 40 driving pulley 20 carries out sawing-like motion,
The emulsion flowed out in the liquid return hole of hydraulic motor 40 enters go back to the connection chamber 73 in the normal opened type two-position valve 70 in liquid valve group, and one
The throttle orifice 721 that part is flow back in fluid reservoir by liquid back pipe road 42, a part is offered in spool 72 enters choke valve 50
Admission chamber 51, the emulsion in admission chamber 51 arrives out sap cavity 55 through intercommunicating pore 56 and connects liquid outlet 52 and flow to cooling and disappear
Arc pipeline 43, is ejected on sawing active section 31 by cooling extinguishing arc emulsion shower nozzle 431；When cooling extinguishing arc pipeline 43 is because of blocking etc.
When reason normally can not carry emulsion, now cooling extinguishing arc emulsion shower nozzle 431 cannot normal injection emulsion, liquid outlet
52, going out the emulsion accumulation in sap cavity 55, intercommunicating pore 56 and admission chamber 51, the emulsion of this admission chamber 51 acts on spool 72
On major diameter end face, owing to the two ends face area of spool 72 exists difference in size, so, the pressure that spool about 72 two ends are subject to
Power is different, promotes the spool 72 in Fig. 3 state to be moved to the left its suffered making a concerted effort in conjunction with spring 74, closes connection chamber 73 and spool chamber
The connection position of 711, thus close connection chamber 73, namely close liquid back pipe road 42, from the point of view of hydraulic motor 40, do not have
There are back liquid path, hydraulic motor 40 the most just can only stop operating.Sawing-like motion stops therewith, also would not continue to produce fire
