The valve rod 2 is horizontally arranged and is screwed into the threaded hole 12, and the valve rod 2 is moved toward or away from the mounting groove 11 by rotating the valve rod 2. An annular clamping groove 21 is formed in one end, close to the mounting groove 11, of the valve rod 2, the annular clamping groove 21 is formed in the circumferential direction of the valve rod 2, the clamp spring 3 is clamped in the annular clamping groove 21 through an elastic mode, and the clamp spring 3 is located in the mounting groove 11.

In practical application, outer pillar 9 fixed connection is in the lower extreme of mounting groove 11, and interior pillar 10 activity wears to locate in mounting groove 11, and outer pillar 9 cover is located interior pillar 10, through rotating valve rod 2 for valve rod 2 moves towards the one end that is close to mounting groove 11, in order to support tightly interior pillar 10 in the mounting groove 11, thereby realizes the fixed to interior pillar 10. Wherein, through rotating valve rod 2 for when valve rod 2 moves towards the one end that keeps away from mounting groove 11, even to valve rod 2 excessive rotation, the jump ring 3 butt in mounting groove 11 is in the inside wall of valve body 1 to restriction valve rod 2 continues to remove, thereby can effectively restrict valve rod 2 and drop from valve body 1.

Referring to fig. 2, in some embodiments, the inner sidewall of the valve body 1 is provided with a relief groove 13, the relief groove 13 is disposed along a horizontal direction, and the relief groove 13 is in communication with the mounting groove 11 and the threaded hole 12. The diameter of the groove 13 of stepping down is greater than the external diameter of jump ring 3 to and the length of the groove 13 of stepping down is greater than the length of jump ring 3, make jump ring 3 and the tip homoenergetic of valve rod 2 inlay and establish and place in the groove 13 of stepping down, avoid interior pillar 10 to wear to locate in the mounting groove 11 in-process as far as possible, the tip of valve rod 2 blocks interior pillar 10, thereby is convenient for adjust the position of interior pillar 10.

Referring to fig. 1 and 2, in some embodiments, the valve stem 2 further includes a handle 4, where the handle 4 is integrally connected to an end of the valve stem 2 remote from the mounting groove 11, and the handle 4 is for a worker to hold, so that the worker applies a force to rotate the valve stem 2, thereby facilitating adjustment of the abutting state against the inner post 10.

In some embodiments, the height adjusting valve further includes a supporting seat 5 and an elastic member 6, where the supporting seat 5 is slidably connected in the valve body 1 along a horizontal direction and partially protrudes out of the valve body 1, the elastic member 6 is a spring, and in other embodiments, an elastic column may also be made, one end of the elastic member 6 is elastically abutted against the peripheral side of the valve body 1, and the other end is elastically abutted against a portion of the supporting seat 5 protruding out of the valve body 1, so as to drive the supporting seat 5 to be close to the valve stem 2. When needs support tightly to interior pillar 10, through rotating valve rod 2 for valve rod 2 butt in butt seat 5, in order to compress elastic component 6, and order about butt seat 5 to be close to and support tightly in interior pillar 10, because butt seat 5 is great with interior pillar 10's area of contact, can improve the stability of supporting tightly to interior pillar 10, also can reduce the pressure of supporting tightly to interior pillar 10 and lead to its surface to collide with the damage. When the valve rod 2 releases the abutment of the abutment 5, the elastic member 6 drives the abutment 5 to reset, so that the abutment 5 moves towards one end close to the valve rod 2, and the inner support column 10 is prevented from blocking the inner support column 10 as much as possible in the process that the inner support column 10 penetrates the mounting groove 11.

The implementation principle of the embodiment is as follows: in practical application, outer pillar 9 fixed connection is in the lower extreme of mounting groove 11, and interior pillar 10 activity wears to locate in mounting groove 11, and outer pillar 9 cover is located interior pillar 10, through rotating valve rod 2 for valve rod 2 moves towards the one end that is close to mounting groove 11, in order to support tightly interior pillar 10 in the mounting groove 11, thereby realizes the fixed to interior pillar 10. Wherein, through rotating valve rod 2 for when valve rod 2 moves towards the one end that keeps away from mounting groove 11, even to valve rod 2 excessive rotation, the jump ring 3 butt in mounting groove 11 is in the inside wall of valve body 1 to restriction valve rod 2 continues to remove, thereby can effectively restrict valve rod 2 and drop from valve body 1.
