Embodiment 1:

Referring to FIGS. 1-7 , this embodiment provides an ultra-high pressure angle valve, including a valve body 100 and a valve core. The valve body 100 provides a mounting base. The valve body 100 of this embodiment has a first end 110 and a second end 120 formed at both ends, an installation cavity 130 formed inside, and a pressure relief port 140 communicating with the installation cavity 130 opened on the side. The valve core is disposed in the installation cavity 130, and the valve core includes a first sealing structure 200, a second sealing structure 300 and an operating mechanism 400.

The first sealing structure 200 includes a valve seat body 210 and a valve seat lock nut 220, and a liquid inlet 221 is formed at the end of the valve seat lock nut 220; a liquid passage 211 is formed inside the valve seat body 210, and a first liquid passage port and a second liquid passage port are formed at both ends of the liquid passage 211, the first liquid passage port is connected to the liquid inlet 221, and the second liquid passage port is connected to the pressure relief port 140;

Specifically, the outer surfaces at both ends of the valve seat body 210 respectively form a first conical surface 212 and a second conical surface 213, that is, the valve seat body 210 as a whole is a hollow olive-shaped design with symmetry at both ends, and a first conical groove is formed at the contact point between the valve body 100 and the valve seat body 210, and the first conical groove is adapted to the first conical surface 212, and the two have a sealing effect when they are against each other; a second conical groove is formed at the contact point between the valve seat lock nut 220 and the valve seat body 210, and the second conical groove is adapted to the second conical surface 213, and the two have a sealing effect when they are against each other;

The valve seat lock nut 220 is threadedly connected to the valve body 100. By tightening the valve seat lock nut 220, the first conical groove abuts against the first conical surface 212, and the second conical groove abuts against the second conical surface 213, so that the valve seat body 210 is detachably mounted on the first end portion 110;

The second sealing structure 300 includes a valve cone 310, the valve cone 310 is slidably connected to the mounting cavity 130, and the valve cone 310 is disposed close to the second liquid port;

The operating mechanism 400 is disposed at the second end portion 120 and is linked to the valve cone 310. The operating mechanism 400 drives the valve cone 310 to approach or move away from the second liquid passage port, thereby opening or closing the liquid passage 211, thereby achieving a dynamic sealing effect when the valve cone 310 moves up and down.

The ultra-high pressure angle valve of this embodiment has a high-pressure fluid inlet located at the valve seat lock nut 220 below the valve body 100, and an outlet located at the side of the valve body 100, and the traditional straight-through structure is changed into an angle valve form, which effectively reduces the wear and tear of the impact seal caused by high-pressure fluid or entrained impurities, resulting in seal failure; when in use, when the ultra-high pressure angle valve is in an open state, the operating mechanism 400 drives the valve cone 310 away from the second liquid port, so that the liquid passage 211 is opened, and the fluid enters from the liquid inlet 221 at the bottom of the valve seat lock nut 220, and is discharged from the pressure relief port 140 on the side of the valve body 100 after passing through the liquid passage 211; when the ultra-high pressure angle valve is in a closed state, the operating mechanism 400 drives the valve cone 310 close to the second liquid port, at which time the valve cone 310 and the valve seat body 210 are tightly attached to form a sealing ring belt, and the fluid enters from the liquid inlet 221 at the bottom of the valve seat lock nut 220, and is blocked by the sealing ring belt when passing through the liquid passage 211, thereby realizing the cutoff of the high-pressure fluid. In this embodiment, the valve seat body 210 is separated from the valve body 100 as an independent part, and is detachably mounted on the valve body 100 with the valve seat lock nut 220, which is convenient for replacement and maintenance. The valve seat body 210 is a hollow olive-shaped design with symmetry at both ends, and conical sealing surfaces are processed at both ends to form a sealing structure with the valve body 100 and the valve seat lock nut 220 respectively; a liquid passage 211 is formed inside for fluid to pass; at the same time, the valve cone 310 approaches or moves away from the end of the liquid passage 211 under the control of the operating mechanism 400, so that the liquid passage 211 is opened or closed to realize fluid on-off control. The first sealing structure 200 with a detachable design is easy to replace under the condition of satisfying its liquid flow and sealing properties. When the sealing structure of the valve seat body 210 and the valve cone 310 is damaged, it can be repaired by replacing the valve seat body 210, effectively extending the service life of the ultra-high pressure valve.

The valve cone 310 of this embodiment is formed with a third conical surface 311 at one end near the second liquid passage opening, and a liquid passage gap is formed between the third conical surface 311 and the second liquid passage opening. The third conical surface 311 cooperates with the second liquid passage opening to improve the sealing performance between the valve cone 310 and the valve seat body 210. When the second liquid passage opening is slightly worn, the third conical surface 311 can be pushed to compensate. In some preferred embodiments, the opening can control the size of the liquid passage gap between the second liquid passage opening and the third conical surface 311, thereby controlling the fluid volume or fluid flow rate.

Specifically, the second sealing structure 300 further includes a support sleeve 320 , a pressing sleeve 330 and a valve cover 340 .

The sealing gasket 350 is generally made of a rubber composite material and is disposed between the support sleeve 320 and the pressing sleeve 330. When in use, the valve cover 340 is tightened and pressure is applied through the pressing sleeve 330, so that the sealing gasket 350 is squeezed and deformed and radially expanded, so that it is close to the valve cone 310 and the installation cavity 130 to play a sealing role.

Furthermore, a first sealing groove is provided on the contact surface between the pressing sleeve 330 and the valve body 100, and a second sealing groove is provided on the contact surface between the pressing sleeve 330 and the valve cone 310;

When in use, the external teeth on the surface of the valve cover 340 are first separated from the internal teeth of the locking ring 510, so that the valve cover 340 obtains rotational freedom, and after tightening the valve cover 340, the locking plate 500 is sleeved on the surface of the valve cover 340, and the internal teeth of the locking ring 510 are meshed with the external teeth of the valve cover 340, and then the fixing portion 520 is fixed to the valve body 100 by bolts, and the valve cover 340 is locked to prevent loosening during use.

The operating mechanism 400 of this embodiment includes an operating rod 410, wherein two ends of the operating rod 410 respectively form a connecting end 411 and a driving end 412, and a connecting portion 413 is formed on the side; wherein the connecting end 411 is connected to the valve cone 310 through a retaining ring 420, the connecting portion 413 is threadedly connected to the valve cover 340, and the driving end 412 is used to input torque; when in use, torque is input to the operating rod 410 through the driving end 412, so that the operating rod 410 rotates relative to the valve cover 340, thereby driving the valve cone 310 to approach or move away from the second liquid outlet, so that the liquid passage 211 is opened or closed.

The operating rod 410 can input torque by connecting to a servo motor or manually. The operating rod 410 of this embodiment inputs torque manually for easy control.
