Furthermore, since the plurality of sweeping plates 76 are uniformly arranged through the rotating ring 75, each sweeping plate 76 has a large swing amplitude, so as to adapt to the use requirement.
A stop block 526 is arranged on one side of the outer side wall of the rear valve rod 523 close to the connecting hole 525, and a return spring 527 for jointing the valve rod 52 and the valve seat 51 is arranged between the stop block 526 and the inner wall of the gun shell 1; during operation, when the high-pressure squirt needs to be closed, loosen trigger 62, under the higher water pressure effect of reset spring 527 and high-pressure squirt water inlet 2, whole valve rod 52 outwards removes for steel ball 522 is laminated with the arc chamfer precision of disk seat 51, has realized the separation of high-pressure squirt water inlet 2 and delivery port 3, the closing of high-pressure squirt promptly.
An arc chamfer matched and attached with the spherical surface of the steel ball 522 is arranged on one side of the rear valve rod 523 and the valve seat 51 facing the steel ball 522; during operation, the two arc chamfers ensure the close fit between the steel ball 522 and the water inlet 2 and the water outlet 3, the high-pressure water gun is sealed when the high-pressure water gun is shut down, and the close fit between the rear valve rod 523 and the steel ball 522 prevents water from entering the connecting hole 525 to cause the connecting hole 525 and the connecting part 524 to be rusted.
A boss 528 for limiting the movement of the steel ball 522 is arranged at the joint of the connecting part 524 and the rear valve rod 523; during operation, the boss 528 is used for being matched with the rear valve rod 523 to limit the steel ball 522, and can drive the steel ball 522 to move when the high-pressure water gun needs to be opened.
The outer side wall of the valve seat 51 is provided with a ring groove 529, and a sealing ring is arranged in the ring groove 529; during operation, the setting of annular 529 and sealing washer can ensure that valve seat 51 installs the leakproofness in the connecting groove, avoids the phenomenon that the junction of valve seat 51 and connecting groove appears leaking.
The hardness of the steel ball 522 is 58HRC to 65HRC, and the material is 440C stainless steel; during working, the hardness and the material of the steel ball 522 can ensure that the steel ball 522 is processed smoothly and has high precision at the position of the sealing valve line, so that the sealing effect is good, the steel ball 522 is friction-resistant, and the service life of the steel ball 522 is ensured.
Referring to fig. 4, compare with integral valve rod 52 of tradition, the technical scheme that this embodiment provided except above-mentioned advantage, it still has the advantage of maintainability, when valve rod 52 live time is longer has the part to appear damaging, because the detachable construction of valve rod 52 among this technical scheme, can maintain or change this damaged part alone, and compare with integral valve rod 52 of tradition, can't maintain and change extravagant ground step when having avoided valve rod 52 to appear the minor problem, the technical scheme that this embodiment provided, only need to damage the part maintain or change can, it causes unnecessary waste to have avoided whole change.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
