Embodiment 1
[0032] Such as Figure 1-6As shown, this embodiment discloses a valve seat, which includes: a valve seat body 1, the shape of the valve seat body 1 is not limited, as long as it can cooperate with the structure of the nozzle to realize the function of the nozzle, such as the oil pipe body , in this embodiment, the valve seat body 1 is preferably a cylindrical structure, more preferably a cylinder; the valve seat body 1 is provided with a first cylindrical cavity 2, a swirl cavity, and a first sealing cavity that communicate with each other. 3 and the nozzle hole 4. During use, the first cylindrical cavity 2 is in sliding contact with the sphere as much as possible to ensure that the valve core does not skew when the sphere slides. The swirl cavity is set on the first cylindrical cavity Below the cavity 2, its shape is not specifically limited, it can be a regular shape or an irregular shape, such as a cylindrical cavity, a spherical cavity (non-integral), a frustum cavity, a c...
Embodiment 2
[0036] Such as Figure 7 with Figure 8 As shown, this embodiment discloses a high-pressure oblique-entry nozzle, which includes an oil pipe body 18, and the lower end of the oil pipe body 18 is socketed with the outer surface of the valve seat body 1 of the valve seat, so that the fluid passes through the platform. The shape structure 6 enters the swirl cavity through the diversion hole 8, so that the fluid rotates and flows downward in the swirl cavity, which has more impact force at this time, wherein the valve seat is the valve seat structure in embodiment 1; Comprising a spool 16, the lower end of the spool 16 is connected with a spheroid 17, the spheroid 17 can select an existing spheroid of any shape, can be a whole spheroid, also can be a part of the spheroid, the spheroid 17 and the second spheroid A sealed cavity 3 cooperates to realize the spraying of the nozzle.
[0037] In addition, other structures of the nozzle, such as the shell, the electromagnetic lifting a...
