Installation tool facilitating installation of sliding valve element spring and elastic check ring of shuttle valve

Abstract

The utility model relates to the technical field of mounting tools, and discloses a mounting tool for conveniently mounting a slide valve core spring and an elastic check ring of a shuttle valve, which comprises a slide valve core, and a check ring groove is arranged at the top end of the outer surface of the slide valve core. By arranging the guide column, the push sleeve, the check ring groove and the elastic check ring, when an operator presses the push sleeve downwards, the push sleeve pushes the first gasket and the elastic check ring in sequence, the first gasket moves downwards along the outer surface of the sliding valve element and compresses the spring, and then the elastic check ring moves downwards along the outer surface of the guide column. Due to the fact that the guide column is designed to be conical, the elastic check ring is gradually opened in the movement process, due to the fact that the elastic check ring is made of carbon steel, the elastic check ring has good elasticity, when the elastic check ring moves to the position of the check ring groove, the elastic check ring instantly shrinks into the check ring groove, and at the moment, the elastic check ring blocks the overall movement of the first gasket. Therefore, the function of quickly assembling the elastic check ring to the sliding valve element is achieved.

[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0029] As Figures 1 to 10 Indicated, the utility model provides a kind of installation tool of slide valve core spring and elastic check ring of convenient installation shuttle valve, including:

[0030] Slide valve core 1, the top end of the outer surface of slide valve core 1 is provided with check ring groove 2;

[0031] Mounting mechanism, mounting mechanism is arranged at the top end of slide valve core 1;

[0032] Wherein, mounting mechanism includes guide column 3, the outer surface of guide column 3 is movably sleeved with elastic check ring 4, the outer surface of elastic check ring 4 is movably connected with first gasket 5, and the top end of first gasket 5 is movably connected with push sleeve 6.

[0033] When the operator presses down the push sleeve 6, the push sleeve 6 will press the first gasket 5 and the elastic retaining ring 4 in turn, at this time, the first gasket 5 will be driven by the push sleeve 6 to move downward along the outer surface of the spool 1, and then the push sleeve 6 will press the elastic retaining ring 4, at this time, the elastic retaining ring 4 will move downward along the outer surface of the guide column 3, and since the guide column 3 is designed in a conical shape, the elastic retaining ring 4 will gradually open during the downward movement, and when the elastic retaining ring 4 moves to the position of the retaining ring groove 2, the elastic retaining ring 4 will instantaneously contract and be clamped inside the retaining ring groove 2.

[0034] The bottom end of the first gasket 5 is movably connected with a spring 7, and the inside of the spring 7 is movably sleeved with the outer surface of the spool 1.

[0035] When the first gasket 5 moves downward along the outer surface of the spool 1, the spring 7 will be compressed, and when the elastic retaining ring 4 is clamped inside the retaining ring groove 2, the movement of the first gasket 5 will be blocked, and the spring 7 will be locked, thereby achieving the effect of assembling the whole spool 1.

[0036] The bottom end of the spring 7 is movably connected with a second gasket 8, and the inside of the second gasket 8 is movably sleeved with the outer surface of the spool 1.

[0037] Due to the design of the second gasket 8, the spring 7 will be well supported.

[0038] The outer surface of the spool 1 is movably sleeved with a base 9, and the inner diameter of the base 9 is consistent with the maximum diameter of the spool 1.

[0039] Due to the design inside the base 9, the spool 1 will be well supported.

[0040] The bottom end of the base 9 is provided with a circular groove 11, and the inner diameter of the circular groove 11 is consistent with the diameter of the bottom end of the push sleeve 6.

[0041] Due to the design of the circular groove 11, the push sleeve 6 can be sleeved inside the circular groove 11, and at this time, the circular groove 11 will well accommodate the push sleeve 6 and the guide column 3.

[0042] The elastic retaining ring 4 is made of carbon steel, and a notch is formed in the elastic retaining ring 4.

[0043] Since the elastic retaining ring 4 is made of carbon steel, the elastic retaining ring 4 has good structural strength and excellent elasticity, and since the notch is formed in the elastic retaining ring 4, the elastic retaining ring 4 is convenient to expand and contract.

[0044] The working principle and use process of the utility model are as follows:

[0045] When the installation tool is idle, the guide column 3 will be sleeved in the inside of the push sleeve 6, at the same time the push sleeve 6 will be sleeved in the inside of the circular groove 11, at this time the guide column 3, the push sleeve 6 and the base 9 will be in the state of contraction and integration, thereby achieving the function of convenient storage.

[0046] When the operator assembles the slide valve core 1, first the operator takes out the push sleeve 6 and the guide column 3 from the inside of the circular groove 11, then the operator places the base 9 on the ground, and then places the slide valve core 1 into the inside of the base 9, because the inner diameter of the base 9 is consistent with the maximum diameter of the slide valve core 1, so the base 9 can play a good supporting role on the slide valve core 1, then the second gasket 8 and the spring 7 are sleeved on the outer surface of the slide valve core 1 in turn, then the guide column 3 is placed at the top end of the slide valve core 1, because of the design of the bottom end of the guide column 3 and the top end of the slide valve core 1, at this time the bottom end of the guide column 3 will be in the state of embedding with the top end of the slide valve core 1, thereby preventing the guide column 3 from deviating during the subsequent pressing process, then the operator places the first gasket 5 at the top end of the spring 7, then the operator sleeves the elastic retainer ring 4 on the outer surface of the guide column 3, and then places the push sleeve 6 on the top end of the first gasket 5, at this time the operator presses the push sleeve 6, in this process the outer cylinder of the push sleeve 6 will first extrude and push the first gasket 5, so that the first gasket 5 compresses the spring 7, then the inner cylinder of the push sleeve 6 will extrude and push the elastic retainer ring 4, because the guide column 3 is conical in shape, at this time the elastic retainer ring 4 will be gradually opened while moving downward along the outer surface of the guide column 3 under the drive of the push sleeve 6, when the elastic retainer ring 4 moves to the retainer ring groove 2 during the downward movement, because the elastic retainer ring 4 has excellent elasticity, at this time the elastic retainer ring 4 will instantaneously contract and be clamped in the inside of the retainer ring groove 2, at this time the elastic retainer ring 4 will block the movement of the first gasket 5, thereby locking the spring 7 as a whole, thereby realizing the function of quickly assembling the elastic retainer ring 4 to the slide valve core 1.
