(6) flanged joint 6, the termination of described flanged joint is provided with seal ring 8, then is fixed in the opening end of hollow cavity of described valve body by bolt 7.
The dual circuit flexible pipe explosive valve that a kind of action flow provided by the invention is adjustable, movable valve plug group and spring seat and flanged joint is adopted to be used in combination, when the position of spring seat changes, the pre compressed magnitude of Compress Spring is along with change, thus the stroke of movable valve plug group can be changed, complete the setting of explosion-proof valve action flow; Movable valve plug group is by insert body and position-limited lever Spielpassung simultaneously, solve the integral core easily stuck problem causing draining, flanged joint directly can use ready-made right angle square flange, is secured by bolts on valve body, more saves cost than existing end cap customization.
Further, as shown in Figure 3, one end of matching with described insert body of the second described hydraulic fluid port passage 201 is the conical socket extended out, described boss 303 is frustum, described position-limited lever mounting hole runs through described boss, and the sidewall of described conical socket and the axis angulation of hollow cavity are less than the sidewall of described frustum and the axis angulation of described hollow cavity.One end of the second hydraulic fluid port passage on spring seat is conical socket, boss on insert body is frustum, easier aligned position when insert body and spring seat being sealed and matched when flexible pipe explosion, the sidewall of conical socket and the angle of frustum sidewall inconsistent, form linear sealing at P place when the two is sealed and matched, seal more tight.
Preferably, the 3rd described hydraulic fluid port passage 305 be multiple, be evenly distributed on described insert body 301.Make the connection of oil circuit more smooth and easy.
Further, as shown in Figure 4, described spacer 5 is multiple, and the thickness of each spacer is different.The spacer that multiple thickness is different is set, makes the quantity by reducing and increase spacer more easily change the pre compressed magnitude of Compress Spring.
The assembly relation of the dual circuit flexible pipe explosive valve that a kind of action flow provided by the invention is adjustable is: first, select one end of valve body 1, first spring seat 2 is put into the hollow cavity of valve body, then the spacer 5 chosen is loaded valve body hollow cavity 101, and by bolt 7, right angle square flange and seal ring 8 are fixed on this end of valve body 1, finally, first Compress Spring 4 is loaded successively from the other end opening of valve body hollow cavity, movable valve plug group 3, second Compress Spring is loaded successively again at the other end of movable valve plug group 3, second spring seat and the spacer corresponding with this end, by corresponding bolt, another right angle square flange is fixed on the other end of valve body 1 again, thus complete assembling, due to two spring seats being equipped with the second hydraulic fluid port passage, therefore two the second hydraulic fluid port passage A and B are formed in this explosive valve.In assembly process, all parts keep coaxial with the hollow cavity of valve body.
Be pipeline connecting figure when the adjustable dual circuit flexible pipe explosive valve working state figure of action flow and application as shown in Figure 3 and Figure 5.When hydraulic system applications, suspended load oil cylinder 9 and system superintendent road 10 is connected with 2 flexible pipes 11, article two, the homonymy of flexible pipe is all connected by the dual circuit flexible pipe explosive valve that a kind of action flow provided by the invention is adjustable, the A mouth of two explosive valves is connected by flexible pipe 11, and the B mouth of two explosive valves is connected by flexible pipe 11.The first hydraulic fluid port channel C connected system main line 10 of two explosive valves, another connects suspended load oil cylinder 9, when in two flexible pipes 11 bursts, the hydraulic fluid flow rate of the second hydraulic fluid port passage A or B of the explosive valve that these flexible pipe two ends connect increases rapidly, pressure will reduce rapidly, the opposite side of the explosive valve be then connected with another flexible pipe 11 promotes Compress Spring under the effect of high pressure, until the frustum of movable valve plug group contacts with the conical socket of spring seat form linear sealing, thus block the second hydraulic fluid port passage of this side, and the second hydraulic fluid port passage of opposite side normally works, and then protective system main line and suspended load oil cylinder are normally acted on by another flexible pipe.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
