[0003] However, this patent has the following problems during use: the staff cannot identify the position of the ball valve core, that is, the staff cannot understand the current opening and closing status of the pipeline, and because the square plug rod and the rotating shaft are set separately, the handle can rotate idly, so that the handle cannot guide to the previous adjustment position of the ball valve core, which increases the difficulty of maintenance for the staff. Utility Model Content

[0012] Furthermore, the end of the adjusting rod is configured to be pointed.
[0013] In the above technical solution, the utility model provides a direct buried fully welded ball valve with the following beneficial effects:
[0014] By setting up the positioning mechanism, since the installation direction of the turning handle is consistent with the direction of the through hole of the ball valve core, the turning handle always points to the direction of the through hole of the ball valve core.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0026] See also Figure 1-5 A directly buried fully welded ball valve comprises a valve body 1, a rotating shaft 11 is installed in the valve body 1, a ball valve core 12 is fixedly connected to the rotating shaft 11, a limiting hole 13 is provided on the rotating shaft 11, a limiting rod 2 is inserted in the limiting hole 13, a turning handle 3 is also fixedly connected to the end of the limiting rod 2, a receiving groove 14 is provided in the valve body 1, the limiting rod 2 is arranged in the receiving groove 14, the installation direction of the turning handle 3 is consistent with the through hole direction of the ball valve core 12, and a positioning mechanism is also included, the positioning mechanism comprises a positioning piece 21 fixedly arranged on the limiting rod 2, a positioning groove 22 matched with the positioning piece 21 is provided at the upper end of the valve body 1; a reset mechanism is also provided in the receiving groove 14. Through the positioning mechanism, since the installation direction of the turning handle 3 is consistent with the direction of the through hole of the ball valve core 12, the turning handle 3 always points to the direction of the through hole of the ball valve core 12. After adjusting the opening and closing of the pipeline, the limit rod 2 is locked to the upper end of the valve body 1, so that the turning handle 3 cannot be rotated, so that the turning handle 3 can still point to the direction of the through hole of the ball valve core 12, so that the staff can observe the opening and closing of the pipeline from the outside, and after adjustment, the turning handle 3 can be prevented from being accidentally touched to prevent affecting the opening and closing of the pipeline.
[0027] In an embodiment further provided by the utility model, the positioning member 21 is arranged in a cross shape, so that after the limit rod 2 rotates ninety degrees to change the direction of the ball valve core 12, the positioning member 21 can still be locked in the positioning groove 22. The positioning member 21 can also be distributed in a "M" shape, and the angle between each line must be maintained at forty-five degrees.
[0028] In an embodiment further provided by the utility model, the reset mechanism includes a plurality of fixed springs 4, each end of the spring 4 is respectively fixedly connected to the upper end of the valve body 1 and the reset plate 41, a reset groove 42 is provided on the reset plate 41, a support plate 43 is rotatably connected in the reset groove 42, and the support plate 43 is fixedly connected to the rotating shaft 11.
[0029] In the embodiment further provided by the present invention, a plurality of sliders 44 are provided on the side wall of the reset plate 41, and a slide groove 45 adapted to the slider 44 is provided on the valve body 1, and the slide groove 45 is communicated with the receiving groove 14. The slider 44 can improve the stability of the reset plate 41 sliding in the receiving groove 14, and can prevent the support plate 43 from driving the reset plate 41 to rotate, thereby affecting the performance of the spring 4.
[0030] In an embodiment further provided by the present invention, the outer surfaces of the limit rod 2 and the valve body 1 are both provided with an anti-corrosion coating.
[0031] In the embodiment further provided by the present invention, an adjustment mechanism is also included, and the adjustment mechanism includes a plurality of support arms 5 fixedly connected to the valve body 1, and an adjustment rod 51 is threadedly connected to the support arm 5. Due to the influence of ground buildings or other pipelines, it is difficult to control the laid pipelines to be on the same horizontal plane. Through the adjustment mechanism, the position of the valve body 1 relative to the ground and the pipeline can be adjusted so that the valve body 1 can be better connected to the pipeline.
[0032] In an embodiment further provided by the present invention, the end of the adjusting rod 51 is pointed to facilitate insertion into the soil.
[0033] Working principle:
[0034] In the initial state, the positioning member 21 is located in the positioning groove 22, and the support plate 43 is located in the reset groove 42. Pressing the turning handle 3 drives the limit rod 2 to move and plug into the limit hole 13 on the rotating shaft 11. The positioning member 21 is disengaged from the positioning groove 22. At the same time, the movement of the limit rod 2 drives the movement of the support plate 43. The movement of the support plate 43 drives the extension of the spring 4 through the reset plate 41. The turning handle 3 rotates through the limit rod 2 to drive the rotating shaft 11 to rotate synchronously. The rotation of the rotating shaft 11 drives the ball valve core 12 to rotate synchronously, thereby completing the position adjustment of the ball valve core 12. Since the through-hole directions of the turning handle 3 and the ball valve core 12 are consistent, the staff can judge the opening and closing status of the ball valve core 12 from the outside of the valve body 1, which is convenient for the staff to adjust the opening and closing of the pipeline from the outside. After adjusting the ball valve core 12, loosen the turning handle 3, so that the stretched spring 4 drives the support plate 43 to move through the reset plate 41, and the support plate 43 moves the limit rod 2 to reset to the initial position. Since the positioning member 21 is arranged in a cross shape, the positioning member 21 moves back to the positioning groove 22, the limit rod 2 is locked, and the turning handle 3 cannot be rotated to prevent accidental touch to change the opening and closing state of the pipeline.
[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
