Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-5, the present invention provides an embodiment: a ball body of a cold spray ball valve comprises a ball body 1, a through hole 7 arranged on the ball body 1 and a connecting block 3 separated from the ball body 1; the side of the connecting block 3 is provided with a protrusion 9, and the protrusion 9 is connected with the groove 6 arranged on the ball body 1 in a matching manner, so that the ball body 1 and the connecting block 3 are assembled and separated. Through the technical scheme, the connecting block 3 of the device is directly separated from the sphere 1, so that the material of the sphere 1 is the same as that of the connecting block 3 on one hand, the problem that the existing sphere and the connecting block need to be manufactured independently is solved, and on the other hand, the structure between the connecting block 3 and the sphere 1 is optimized, and particularly, the connecting block 3 can be consistent with the spherical surface of the sphere 1 after being assembled;

in addition, by the scheme, the device saves materials and simplifies the manufacturing mode of the connecting block 3, so that the overall manufacturing cost of the ball body 1 is greatly reduced; utilize protruding 9 and recess 6's looks adaptation to be connected simultaneously for assembly clearance is little between spheroid 1 and the connecting block 3, and the cooperation is inseparable between spheroid 1 and the connecting block 3, has solved the problem that appears rocking between spheroid 1 and the connecting block 3.

In order to be able to rotate the ball 1, the connecting piece 3 is therefore connected to the valve rod 2 provided.

Because the connecting block 3 with after the spheroid 1 separates the corresponding position on the spheroid 1 is formed with notch 4, wherein, recess 6 is located on two sides of notch 4, consequently make on connecting block 3 can push spheroid 1, and then the assembly of the connecting block 3 of being convenient for sets up recess 6 on the side of notch 4 simultaneously, also makes the area of contact between arch 9 and the recess 6 on the connecting block 3 more, strengthens the reliability of connecting between the two, further reduces the problem that the two appears rocking after connecting.

The lower bottom surface of the notch 4 is also provided with a positioning hole 5; the positioning hole 5 is in adaptive connection with the cylindrical shaft 13 arranged on the valve rod 2, so that after the valve rod 2 is installed on the connecting block 3, the connecting block 3 and the ball body 1 are further fixed through the matching of the cylindrical shaft 13 and the positioning hole 5, and in addition, through the installation mode, whether the assembly between the connecting block 3 and the ball body 1 is in place can be judged, for example, the cylindrical shaft 13 cannot be assembled with the positioning hole 5, the assembly between the front connecting block 3 and the ball body 1 is not in place, otherwise, the rotation assembly is proved to be in place.

In order to facilitate the installation of the handle and avoid the phenomenon that the handle slips when the ball body 1 is driven after the handle is installed, a connecting groove 11 used for being connected with the handle is further formed in one end, far away from the cylindrical shaft 13, of the valve rod 2.

When a pipeline conveys a medium, the pressure, the flow or the flow rate of the medium inside the pipeline generally needs to be monitored, and the existing method is to directly open a hole on the pipeline and then install a sensor, although the above-mentioned method can realize the monitoring of the flow, the pressure or the flow rate, the whole structure of the pipeline is damaged, and therefore:

the centre of a circle department of valve rod 2 is equipped with and runs through completely the through-hole 10 of valve rod 2, consequently the device can install the sensor in through-hole 10, guarantees that the overall structure of pipeline does not receive the destruction, and through-hole 10 runs through valve rod 2 completely simultaneously, consequently is convenient for again the replacement and the installation of sensor.

Because connecting block 3 through be equipped with connecting hole 8 with valve rod 2 is connected, consequently make easy dismounting between valve rod 2 and the connecting block 3, especially, when the sensor is difficult to take out in valve rod 2 inside, can realize the replacement of sensor through changing valve rod 2.

Further, one end of the valve rod 2 is in threaded fit with the connecting hole 8 through an external thread 12, wherein the screwing direction of the external thread 12 and the connecting hole 8 is opposite to the direction in which the valve rod 2 drives the ball 1 to rotate.

In order to further facilitate the separation of the connecting block 3 from the sphere 1, the sphere 1 and the connecting block 3 are separated by adopting a wire cutting mode between the connecting block 3 and the sphere 1, and the protrusion 9 and the groove 6 are synchronously formed by adopting the wire cutting mode, so that the technology is mature, the processing is convenient, and the processing cost is low; alternatively, laser cutting is also possible, but this is expensive and does not require such high machining precision for separating the connecting piece 3 from the ball 1.

The fitting between the connecting block 3 and the ball 1 is tight because the number of the protrusions 9 is equal to the number of the grooves 6. Especially, solved on the current spheroid notch and current valve rod connecting portion between because of the fit clearance is big, for a long time use the back, the more and more big problem in cooperation department clearance

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
