Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1-4, an adjusting valve rod comprises a connector 8 and a plug post 10, wherein the bottom end of the plug post 10 is inserted into the connector 8, a through groove 11 is formed in the inner side of the plug post 10, a spring 9 is fixedly connected to the bottom of the inner side of the connector 8 and the top end of the through groove 11, and an outer gear ring 13 is arranged on the outer portion of the plug post 10 close to the upper position.

In this embodiment, the inner wall of connector 8 and the outer wall of inserting post 10 all are the hexagon structure, and spring 9 is provided with two, and two spring 9 concentric circles set up.

The connector 8 and the inserting column 10 which are in butt joint in the hexagonal structure can be stressed to rotate when the inserting column 10 rotates, so that the limiting effect is achieved between the connector 8 and the inserting column 10.

The utility model provides a governing valve with adjusting valve rod, includes valve body 1, and ring flange 2 is all installed at the both ends of valve body 1, and boss 3 is installed to the outside position placed in the middle of valve body 1, and the inside fixed mounting of valve body 1 has seal receptacle 5, and the inboard rotation of seal receptacle 5 is connected with valve ball 6, and the inside central point of valve ball 6 puts and runs through there is passageway 7.

In this embodiment, the bottom end of the connector 8 is fixedly connected to the valve ball 6, and a sealing gasket is disposed on a contact surface between the connector 8 and the convex pillar 3.

When the inserting column 10 is rotated, the inserting column 10 drives the connector 8 to rotate, the connector 8 drives the valve ball 6 to rotate, and therefore the purpose of adjusting the opening degree of the valve is achieved, and the sealing gasket can increase the sealing performance between the connector 8 and the convex column 3.

In this embodiment, the top end of the inserting column 10 is provided with a rotating handle 4, and the rotating handle 4 is arranged in a diamond shape.

The inserted column 10 is operated through the rotating handle 4, so that the inserted column 10 can do work in the vertical direction or the circumferential direction.

In this embodiment, the inner surface of the convex column 3 is provided with an inner tooth socket 12 near the top, and the inner tooth socket 12 is engaged and matched with the outer tooth ring 13.

Because the convex column 3 and the valve body 1 are fixed, after the outer gear ring 13 is meshed with the inner gear groove 12, the inserted column 10 cannot be rotated, and the connector 8 can be always kept at a fixed position, so that the valve ball 6 cannot rotate under pressure.

It should be noted that, the utility model relates to an adjusting valve rod and have governing valve of this valve rod, when using, 2 and the external pipe connection of ring flange through both ends with valve body 1, medium in the pipeline enters into valve body 1 interior back, receive blockking of valve ball 6 and seal receptacle 5, lead to the unable circulation of medium, handheld turning handle 4 vertical rebound, make interior tooth's socket 12 break away from with outer ring gear 13, can rotate insert post 10 through turning handle 4 after breaking away from, insert post 10 drives connector 8 and rotates, connector 8 drives valve ball 6 and rotates, when passageway 7 of valve ball 6 spills seal receptacle 5, the medium can circulate through passageway 7, after the operation is accomplished, loosen turning handle 4, spring 9 elasticity shrink, drive insert post 10 downstream, make interior tooth's socket 12 and outer ring gear 13 meshing, insert post 10 is under the condition that non-manual operation lifted this moment, insert post 10 can't be rotated, lead to valve ball 6 remain stable throughout.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
