Inlet end is the cylindrical body of hollow, and hoop has multiple inlet hole; The joint of suction tude is drum type joint, and drum type joint inside has annular air inlet duct, and this drum type joint side is to connection suction tude, and this drum type joint can axial rotation, adjustment airintake direction.
In suction valve described in the utility model, exhaust end is provided with outside thread, matches with fitting seat.
In suction valve described in the utility model, the end of inlet end is provided with caging bolt, and the joint of suction tude is fixed on suction valve by this caging bolt.
In suction valve described in the utility model, the joint of this suction valve and fitting seat is provided with seal ring.
In suction valve described in the utility model, the joint of drum type joint and inlet end is provided with O type circle.
In suction valve described in the utility model, described spool comprises sealing plug and axle, and sealing plug is connected with push rod by axle, and axle is provided with spring, and spring is limited between push rod and sealing plug.
In suction valve described in the utility model, sealing plug is the conical surface near the top of inlet end.
The beneficial effect that the utility model produces is: inlet end hoop of the present utility model is provided with multiple inlet hole, the joint of suction tude is drum type joint, inside has annular air inlet duct, and make drum type joint can axial rotation, adjustment airintake direction, thus realize hoop air inlet, latus rectum size is arranged, the demand of large volume air bag fast aeration can be met.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the scheme of installation of the utility model embodiment suction valve;
Fig. 2 is the structural representation of the utility model embodiment suction valve.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, the suction valve of the utility model embodiment comprises the housing 9 of hollow, and housing 9 is the main platforms installed each part and form suction valve.Shell one end is the inlet end be connected with the joint of suction tude, the other end of housing is the exhaust end 1 be connected with the fitting seat 2 of capsule series products, enclosure interior is provided with step, the side of step is provided with spool, exhaust end is provided with push rod 5, this push rod 5 has air outlet hole, between push rod 5 and spool, is provided with spring 6.
Inlet end is the cylindrical body of hollow, and hoop has multiple inlet hole, and the joint of suction tude is drum type joint 3, and drum type joint 3 inside has annular air inlet duct, and this drum type joint side is to connection suction tude 4, and this drum type joint can axial rotation, adjustment airintake direction.
In an embodiment of the present utility model, the end of inlet end is provided with caging bolt 11, and the joint of suction tude is fixed on suction valve by this caging bolt 11, the two Spielpassung.Drum type joint 3 limits its axial motion by caging bolt 11, but can, around axial flexible rotating, make suction tude automatically adjust airintake direction, can not distortion and bending.Drum type joint 3 inside has annular air inlet duct, is convenient to the hoop flowing of gas, from the air inlet of housing hoop inlet hole.
Exhaust end 1 is provided with outside thread, matches with fitting seat 2.Exhaust end 1 can make whole suction valve install from air bag outside by outside thread, easy to use, inspection and maintenance.
The joint of this suction valve and fitting seat 2 is provided with seal ring 8, to realize the sealing of housing and fitting seat 2, prevents Leakage Gas.
Drum type joint 3 is provided with O type circle 10 with the joint of inlet end, to realize the sealing of housing and drum type joint, prevents Leakage Gas.
In embodiment of the present utility model, as shown in Figure 2, spool comprises sealing plug 7 and axle, and sealing plug 7 is connected with push rod 5 by axle, and axle is provided with spring 6, and spring 6 is limited between push rod 5 and sealing plug 7, can stretch within the specific limits.Sealing plug 7 is the conical surface near the top of inlet end.Sealing plug 7 and spring 6, for opening when positive pressure reaches setting value, realize reverse sealing after air inlet completes.Sealing plug is led by the conical surface near the front portion of inlet end and locates, and ensures reliably to close; Rear portion helps spring 6 by axle and hole, push rod 5 is located and leads, and ensures the stability of axial motion and ensures opening travel.
