Some semicircular through holes are distributed on the large end cylinder of mandrel, total actual internal area of some semi-circular through hole equates with the through hole actual internal area on plug screw.On plug screw, have the little groove for turning plug screw.The string diameter of spring is 1 ~ 2mm, spring length 24 ~ 40mm, spring rate 1 ~ 12N/mm, spring deflection 14 ~ 20mm.
The beneficial effects of the utility model are:
1, the utility model controllable device that integrated liquid flow medium flows on end cap, adopts this combination, has increased the function of end cap, can flowing medium need to be flowed to controllable device formal dress or anti-dress according to difference.
2, the utility model adopts stepped shaft core shaft structure, and front portion is for mounting spring, rear portion and lid formation effective sealing, and the semi-circular hole of opening on it can be used as the passage of fluid, and existing sealing has again Security, compact structure.
3, the utility model is pure mechanical structure, and reliable in action, is quick on the draw, and installs simply, has reduced the complexity of device, has improved the practical effect of device.
4, the utility model adopts conical surface seal, avoids the steel ball often using in tradition participate in sealing the structural complexity bringing and process the difficulty of installing, and sealing surface is not easy to wear, and part life is long.
5, the utility model can use in liquid, gas medium, is applicable to pipeline, container or other specific occasions, and using scope is wide.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figures 1 to 6, a kind of liquid medium flows to controlled safe cylindrical shell end cap, by lid 1; Mandrel 4; Spring 5; Plug screw 8 forms.
On lid 1, have some cavitys, cavity connects lid two ends, in cavity, is shoulder hole, between the circular port that two diameters of shoulder hole do not wait, connects by inner conical surface 2 transition; It is cylindric that mandrel 4 is ladder, and the top of its large end cylinder is taper, holds greatly on cylinder and have some semicircular through holes, and plug screw 8 is provided with through hole 7(Fig. 5,6).Mandrel 4 is placed in the shoulder hole of cavity, the male cone (strobilus masculinus) of taper is connected with inner conical surface 2 fitted seal, the large end cylinder of mandrel 4 coordinates guiding to be connected with the big column hole of shoulder hole, between the large end cylinder ear end face of mandrel 4 and plug screw 8 interior edge faces, be connected by spring 5 contacts, plug screw 8 is threaded with the big column hole of the shoulder hole rear end of cavity.
Spring 5 is sleeved on mandrel 4, is free state when installation, and spring 5 length are slightly larger than mandrel 4 small end axle body length.Spring 5 one end are against the large end cylinder ear end face of mandrel 4, the other end is against the interior edge face of plug screw 8, plug screw 8 adopts thread connecting mode with end cap 1, be inserted on little groove 6 and be screwed into instrument, carry out the pretightening force of Regulation spring by being screwed into the degree of depth, make the male cone (strobilus masculinus) of taper and the laminating of the inner conical surface of lid 1 of mandrel 4, form effective sealing.In the time that end cap outside exists without active force, mandrel 4 male cone (strobilus masculinus)s match with the inner conical surface 2 of lid 1 and form sealing, and liquid flow medium is implemented to unidirectional cut-out; In the time that end cap external streams medium active force reaches certain value, spring 5 is compressed, mandrel 4 backward mobile liquid flow medium just can be by 8 hole 7 on the through hole 3 on lid 1, semi-circular through hole on mandrel 4 and plug screw from an effluent of lid 1 to opposite side, thereby realizes the flow direction of controlling liquid flow medium.
As shown in Figure 3,4, on mandrel 4, have eight semicircular through holes as runner, thereby suitably improve flow.The gross area of eight semicircular through holes equates with the area of through hole 7 on plug screw 8.Mandrel 4 structures have leading role, have ensured that end cap dams and the switching precision of drainage.Lid 1 thickness can need to be determined by pipeline or structure of container.
The serial scope of spring 5 is: spring filament diameter: 1 ~ 2mm, and spring length 24 ~ 40mm, spring rate 1 ~ 12N/mm, spring deflection 14 ~ 20mm, can select according to different applied external force.
