The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.A kind of wellhead connector, as shown in Figure 1, comprise housing 1 and the end cap 2 that is threaded with housing 1, the inboard of end cap 2 is connected with valve gap 4 through screw 3, and valve gap 4 is provided with valve rod 5 with the axle center of end cap 2, and valve rod 5 is provided with airflow hole 6.Said housing 1 is illustrated in figure 2 as cylindric, and an end of housing 1 is provided with external screw thread 7, and the other end of housing 1 is provided with internal thread 8; Be provided with dividing plate 9 in the endoporus of housing 1, the center of dividing plate 9 is provided with through hole 10.Said end cap 2 is illustrated in figure 3 as the step circle column, the small diameter cylinders face of step cylinder be provided with housing 1 on internal thread 8 corresponding connecting threads 11; The axle center of end cap 2 is provided with round platform hole 12, and the inner side plane of end cap 2 is provided with the screwed hole 13 that is uniformly distributed along the circumference.Said valve gap 4 is illustrated in figure 4 as the step circle column, and the major diameter plane of step cylinder is provided with the fixing hole 14 that is uniformly distributed along the circumference, and the position of fixing hole 14 is corresponding with screwed hole 13 positions on the end cap 2; Valve gap 2 is provided with centre bore 15, and centre bore 15 is a stepped hole, and centre bore 15 medium-small diameter places are provided with seal groove 16, and valve gap 4 also is provided with seal groove 16 with the joint face of end cap 2.Said valve rod 5 is illustrated in figure 5 as the cylinder that an end is a sphere, and cylindrical middle part is provided with boss 17, and sphere one end of valve rod 5 is provided with airflow hole 6, and airflow hole 6 communicates with the air stream outlet 18 that is provided with at boss 17 opposite sides; Be equipped with seal groove 16 on the face of cylinder of the boss 17 and valve rod 5 other ends.Be provided with sealing ring 19 in the said seal groove 16.
