Owing to have employed technique scheme, the beneficial effects of the utility model are described plug-type instantaneous reverse two-position four-way rotary valve assemblies is pure mechanical structure, safe and reliable, the commutation of little moment can be realized, travel position sensing, instantaneous effective commutation, meets the automatic circulating operation demand of diaphragm pump or capsule pump completely.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is the structural representation of the utility model plug-type instantaneous reverse two-position four-way rotary valve assembly.
In figure: 1, initiatively reverse wheel, 2, bearing pin, 3, medium output port P, 4, instantaneous reverse spring, 5, push-and-pull bull stick, 6, reversing pin, 7, passive reverse wheel, 8, flexible hoop tube adaptor, 9, working port B, 10, valve seat, 11, two-position four-way rotary valve, 12, medium input port O, 13, rotary spool, 14, commutate shifting block, and 15, working port A.
Embodiment
As shown in drawings, plug-type instantaneous reverse two-position four-way rotary valve assembly, it is characterized in that: this assembly comprises plug-type instantaneous reverse mechanism, two-position four-way rotary valve (11) and valve seat (10), described plug-type instantaneous reverse mechanism is by push-and-pull bull stick (5), instantaneous reverse spring (4), initiatively reverse wheel (1) and passive reverse wheel (7) composition, described push-and-pull bull stick (5) is connected with valve seat (10) by bearing pin (2), and bearing pin (2) is positioned on the central shaft of initiatively reverse wheel (1), described instantaneous reverse spring (4) one end connects push-and-pull bull stick (5), the other end is connected with valve seat (10), described passive reverse wheel (7) intermeshes with active reverse wheel (1), and a side end face has two reversing pins (6) arranged by several angle, described two-position four-way rotary valve (11) comprises rotary spool (13), medium input port O(12), medium output port P(3), working port A(15) and working port B(9), described rotary spool (13) end sleeve has passive reverse wheel (7) and commutation shifting block (14), described commutation shifting block (14) is positioned at the side that passive reverse wheel (7) has reversing pin (6), and rotate with rotary spool (13).
Described two-position four-way valve rotary valve (11) inside is provided with pressure release balance port, and the valve face before and after commutation is stressed balance, only need overcome the rotational resistance of rotary spool itself during commutation, and the resistance that commutates is little.
Described medium input port O(12), medium output port P(3), working port A(15) and working port B(9) all adopt flexible hoop tube adaptor (8), be convenient to the dismounting of two-position four-way rotary valve, replacing and maintenance.
Working procedure: position shown in accompanying drawing, suppose medium output port P(3) and working port A(15) communicate, working port B(9) and medium input port O(12) communicate, when there being an external force left to promote push-and-pull bull stick (5) rotation, push-and-pull bull stick promotes initiatively reverse wheel (1) and rotates counterclockwise, and passive reverse wheel (7) is that empty set is on rotary spool (13), in several angle, passive reverse wheel (7) rotates clockwise with active reverse wheel (1), but rotary spool (13) is failure to actuate, namely two-position four-way valve rotary valve (11) does not commutate, when push-and-pull bull stick (5) turns over neutral position (push-and-pull bull stick and instantaneous reverse spring are point-blank), external force left lost efficacy, instantaneous reverse spring (4) plays a role, spring force promotes push-and-pull bull stick (5) and rotates continuation rotation, initiatively reverse wheel (1) and passive reverse wheel (7) are also rotated further, when the reversing pin (6) of passive reverse wheel (7) side encounters commutation shifting block (14) on rotary spool (13), commutation shifting block (14) driven rotary spool (13) rotates, two-position four-way valve rotary valve (11) is just forced to realize commutating instantaneously, after commutation, medium output port P(3) and working port B(9) communicate, working port A(15) and medium input port O(12) communicate.Vice versa, so moves in circles.
