[0002] In the Chinese utility model patent: CN210686472U, a ball body of a ball valve jet pump has an opening on one side of the through hole inside the ball body, a nozzle is inserted inside the opening, and a nozzle is opened in the middle of the nozzle, which can realize the state of fluid pressurized injection. However, the nozzle of this structure is too concentrated in the center position. Although it can ensure the effective transmission of the injection force, its action surface is relatively narrow, and the nozzle cannot fully cover the target area. The effect of pressurized injection is not comprehensive enough, which limits its use effect. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a fluid jet-shaped sphere to solve the problem of jet concentration.

[0004] The technical solution of the utility model is as follows: a sphere is arranged to rotate around its central axis, a plurality of regularly arranged injection holes are opened in the sphere, the injection holes penetrate the surfaces of two opposite sides of the sphere and the length directions of the injection holes are arranged perpendicular to the central axis.

[0005] By adopting the above technical solution, multiple injection holes can ensure that the fluid is sprayed out evenly on the sphere, producing a comprehensive jet flow, improving the coverage and effect of fluid injection, especially in scenarios where uniform action of the fluid is required, reducing the injection blind area, and ensuring a more uniform and comprehensive injection effect.

[0006] In one possible design, an inlet cavity is opened in the sphere, and the inlet cavity is located on the inlet side of the injection hole. The inlet cavity is in an expanded shape with a small outside and a large inside. An expansion cavity is also opened between the inlet cavity and the injection hole, and the inner diameter of the expansion cavity is larger than the inner diameter of the inlet cavity.

[0007] With the above design, the inlet cavity is used to gradually guide the fluid into the expansion cavity, and the expansion cavity can expand the spray coverage area and increase the number of spray holes as much as possible.

[0008] In a possible design, the inner diameter of the injection hole gradually decreases from its inlet side to its outlet side.

[0009] With the above design, the fluid in the injection hole will form a gradually increasing pressure, which has the effect of increasing the injection force and helps to improve the injection effect.

[0010] In a possible design, a chamfered neck is provided at the inlet of the injection hole.

[0011] With the above design, the chamfered neck is used to guide the fluid to be squeezed into the injection hole, which helps to increase the fluid pressure.

[0012] In a possible design, the inner diameter of the inlet end of the injection hole is less than 10 mm.

[0013] With the above design, the inner diameter is properly selected to ensure that a jetting effect can be formed.

[0014] In a possible design, an open flow channel is opened in the sphere, and the injection holes are arranged perpendicular to the open flow channel.

[0015] With the above design, this type of ball valve has opening and spraying functions to select the desired scene setting.

[0016] In a possible design, an open flow channel is opened in the sphere, and the injection hole is arranged in line with the open flow channel.

[0017] With the above design, this type of ball valve has shut-off and injection functions to select the desired scene setting. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-3The sphere shown is a fluid jet-shaped sphere, which is arranged to rotate around its central axis. A plurality of regularly arranged jet holes 1 are provided in the sphere, and the jet holes 1 penetrate the surfaces of the two opposite sides of the sphere, so that the two sides of the sphere can be mutually connected. The jet holes 1 can be arranged in multiple layers along the radial direction, and the number of jet holes 1 in each layer is arranged in the circumferential direction, and the number of jet holes 1 in the outer layer is gradually increased compared with the number of jet holes 1 in the inner layer. The length direction of the jet holes 1 is arranged perpendicular to the central axis, so that the jet holes 1 are always on the rotation surface of the sphere. When the fluid passes through the jet holes 1, a jet flow is formed to be output outward, and the uniformly distributed jet holes 1 can expand the effective surface. The sphere of this structure can be used for domestic tap water pipes, so that the output water flow is in the shape of a jet; it can also be used in pipes that need to clean the inner wall, and can be sprayed into the inner wall attachments. During processing and manufacturing, the jet holes 1 are directly drilled on the sphere, and the outlet position of the jet holes 1 is located on the spherical surface of the sphere, which is convenient for processing.

[0025] An inlet chamber 2 is provided in the sphere, and the inlet chamber 2 is located at the inlet side of the injection hole 1. The inlet chamber 2 is in an expanded shape with a small outside and a large inside. An expansion chamber 3 is also provided between the inlet chamber 2 and the injection hole 1, and the inner diameter of the expansion chamber 3 is larger than the inner diameter of the inlet chamber 2. The inlet chamber 2 is used to gradually guide the fluid into the expansion chamber 3, which can gradually guide the fluid into the interior of the sphere, ensuring the smooth flow and uniform distribution of the fluid. The expansion chamber 3 can expand the injection coverage area. The existence of the expansion chamber 3 makes full use of the space inside the sphere, so that more injection holes 1 can be arranged in a limited space. When the fluid enters the expansion chamber 3 from the inlet chamber 2, the fluid can be rapidly diffused due to the increase in space, thereby achieving a wider injection effect.

[0026] The inner diameter of the injection hole 1 gradually decreases from the inlet side to the outlet side. The fluid in the injection hole 1 will form a gradually increasing pressure, thereby increasing the injection force, which not only conforms to the principle of fluid dynamics, but also shows good effects in practical applications.

[0027] A chamfered neck 4 is provided at the inlet of the injection orifice 1, and the chamfered neck 4 is a neck whose inner diameter gradually decreases from the outside to the inside. In the absence of any obstacles, the fluid usually flows smoothly and at a uniform speed. However, when the fluid encounters the chamfered neck 4, its flow state will change significantly. The design of the chamfered neck 4 causes the flow velocity of the fluid to increase rapidly at this point. The increase in flow velocity means that the fluid obtains greater kinetic energy at the neck, which is the result of the combined effect of the continuity principle of the fluid and Bernoulli's law. When the fluid enters the injection orifice 1, its flow velocity is limited by the aperture, the flow velocity decreases, and the kinetic energy is converted into pressure energy, thereby increasing the fluid pressure. The design of the chamfered neck 4 can also reduce the turbulence and eddy current of the fluid at the entrance of the injection orifice 1. Turbulence and eddy current will not only reduce the efficiency of the fluid, but may also cause energy loss and mechanical wear. The chamfered neck 4 can guide the fluid to transition to the injection orifice 1 more smoothly, reducing unnecessary energy loss.

[0028] The inner diameter of the inlet end of the injection hole 1 is less than 10 mm. Experiments have shown that if it exceeds 10 mm, the injection force of the formed jet flow decreases rapidly, so the injection hole 1 needs to have a smaller inner diameter.

[0029] An open flow channel 5 is provided in the sphere, and the injection hole 1 is arranged in a colinear relationship with the open flow channel 5, that is, the injection hole 1 is actually arranged in the open flow channel 5, so that the ball valve using this type of sphere has closing and injection functions. When the open flow channel 5 corresponds to the flow channel in the ball valve seat, the injection effect is achieved, otherwise the flow channel is closed to achieve the function of closing the valve. Embodiment 2

[0030] like Figure 4 , 5 As shown, different from the above-mentioned embodiment, an open flow channel 5 is opened in the sphere, and the injection hole 1 is arranged perpendicular to the open flow channel 5, so that the ball valve using this type of sphere has the functions of opening and injection. When the open flow channel 5 corresponds to the flow channel in the valve seat of the ball valve, the flow channel is unblocked and the valve is opened, otherwise the injection hole 1 corresponds to the flow channel in the valve seat, and the injection effect is achieved.
