Fig. 1 is according to the structural representation of the rotary valve mud pulse generator of the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, in the situation that not conflicting, the feature in the application's embodiment and embodiment can combine mutually.
As shown in Figure 1, according to the rotary valve mud pulse generator of embodiment of the present utility model, comprise urceolus 2, armature spindle 1 and black box, on described urceolus 2, be provided with oil filler point 11, described armature spindle 1 is arranged in described urceolus 2 by a bearing 7, described black box is arranged on described armature spindle 1, make in described urceolus 2, one side of the close described oil filler point 11 of described black box forms annular seal space 9, described black box comprises outside V-shaped seal ring 4, inner side V-shaped seal ring 5, lateral branch pushing out ring 3, medial branch pushing out ring 6 and locating ring 12, described locating ring 12 is fixedly connected with described armature spindle 1, described lateral branch pushing out ring 3 and described medial branch pushing out ring 6 are positioned at the both sides of described locating ring 12, described outside V-shaped seal ring 4 be arranged between described locating ring 12 and described lateral branch pushing out ring 3 and with described armature spindle 1, between the inwall of described urceolus 2, form sealing, described inner side V-shaped seal ring 5 be arranged between described locating ring 12 and described medial branch pushing out ring 6 and with described armature spindle 1, between the inwall of described urceolus 2, form sealing, the lip limit of the lip limit of described outside V-shaped seal ring 4 and described inner side V-shaped seal ring 5 is all towards described locating ring 12 directions, described locating ring 12 is for limiting the distance between described outside V-shaped seal ring 4 and described inner side V-shaped seal ring 5 so that form the space with preset volume between described outside V-shaped seal ring 4 and described inner side V-shaped seal ring 5, described locating ring 12 and described lateral branch pushing out ring 3, described medial branch pushing out ring 6 coordinates described outside V-shaped seal ring 4 and described inner side V-shaped seal ring 5 is fixed and is supported.
Wherein, 8 is that mandrel connector, 10 is motor.
In this technical scheme, described rotary valve mud pulse generator adopts disymmetry formula V-shaped seal ring structure to have good sealing, extreme pressure lubricant can be closed in mud pulse generator to the pressure of outside drilling fluid when offsetting work, reduce the frictional resistance of sealing device, reduce power consumption, improve application life, improve sealing and reliability.
Further, described oil filler point 11 can be unidirectional oil filler point, can effectively prevent that lubrication oil from flowing backwards.
In described rotary valve mud pulse generator, inject extreme pressure lubricant by the unidirectional oil filler point 11 being arranged on urceolus 2 to annular seal space 9, for offsetting external pressure, the frictional resistance while reducing V-shaped seal ring rotation.
