Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a pilot high-pressure clamp stop valve includes a pilot valve a1, one side of the pilot valve a1 is connected with a hand wheel through a rotating shaft, and the opening and closing are realized through the rotation of the arranged hand wheel, so as to realize the inlet and outlet of high-pressure liquid; the outer surface of the main structure connected with the pilot valve A1 is provided with a small hole, so that high-pressure liquid enters the upper cavity of the pilot valve core 10 through the small hole, the thrust of the upper cavity is larger than the jacking force of the lower cavity due to different areas of the upper cavity and the lower cavity, downward stress is synthesized, and the component force of a corresponding hand wheel rotating in a closing manner is very small; one side of the pilot valve A1 is provided with an inner hexagon screw 2, a main structure connected with the pilot valve A1 is formed by splicing an upper structure and a lower structure, the upper structure and the lower structure are fixedly connected through the inner hexagon screw 2, the upper structure is provided with a hand wheel, the lower structure is provided with a pilot valve core 10, the hand wheel realizes the inlet and outlet of high-pressure liquid, and the hand wheel and the pilot valve core 10 form a combined structure to jointly realize small stress of a handle; an O-shaped ring A3 is arranged below the pilot valve A1, a retainer ring A4 is arranged on the outer side of the O-shaped ring A3, a spring 5 is arranged inside the O-shaped ring A3, an O-shaped ring B6 is arranged in the middle of the spring 5, a retainer ring B7 is arranged on the outer side of the O-shaped ring B6, the retainer ring B7 and an O-shaped ring B6 are arranged on the middle position close to the upper side of the pilot valve A1, an O-shaped ring C8 is arranged in the middle of the spring 5, a retainer ring C9 is arranged on the outer side of the O-shaped ring C8, the retainer ring C9 and the O-shaped ring C8 are arranged on the middle position close to the lower side of the pilot valve A1, a pilot valve core 10 is arranged inside the pilot valve A1, the spring 5 is arranged inside the pilot valve core 10, the upper right side and the lower left side of the pilot valve core 10 are connected with, the force of the hand wheel is very small because the resultant stress direction is downward due to the area; the joint 11 is arranged in the valve body 12, an O-shaped ring D13 is arranged around the outer side of the joint 11, and the O-shaped ring D13 is connected with the pilot valve core 10 in a penetrating way.

The working principle is as follows: when the pilot high-pressure hoop stop valve works, a hand wheel of a pilot valve A1 is in a closed state, high-pressure liquid enters the lower end connector 11, and pushes the pilot valve core 10 to the top end of the valve body 12 and then comes out from the upper end connector 11; if the high-pressure liquid needs to be closed, the hand wheel is rotated rightwards, the high-pressure liquid enters the upper cavity of the pilot valve core 10 through the small hole, the area of the upper cavity is larger than that of the lower part of the valve core, so that the thrust of the upper cavity is larger than the jacking force of the lower part, the pilot valve core 10 moves downwards, and the liquid inlet of the lower end connector 11 is closed. The closing function is realized; the force of the handwheel is thus small.

In summary, the following steps: the pilot high-pressure clamp stop valve realizes that the stress of a hand wheel is very small through the arranged pilot control structure, so that the stress of a handle rotating steel ball is very small; and the larger the pressure is, the larger the steel ball is, the pipeline is, the stress of the handle after the sleeve is added to rotate the steel ball is very small, and the handle and the clamping groove of the steel ball are not easy to damage, so that the great safety problem does not exist, and the wealth and property and the life safety of people are guaranteed.
