Description

Technical Field

[0001] The utility model relates to a ball valve, in particular to a V-type ball valve. Background Art

[0002] The V-type ball valve is a valve with a V-shaped opening on one side of the hemispherical valve core. By adjusting the valve core opening, the cross-sectional area of ​​the medium flow is changed, and the flow rate is adjusted. It can also be used for switch control to open or close the pipeline. It has a self-cleaning function and can adjust a small flow rate within a small opening range. It has a large adjustable ratio and is suitable for media containing fibers, fine particles, and slurry.

[0003] The valve core structure in the existing structure is single, and defective products such as deformation or breakage produced during casting greatly affect the structural reliability of the product. At the same time, when the medium passes through the valve core, the noise and vibration generated by the excessive pressure difference between the medium in the pipeline and the valve body will produce large noise. These noises will affect the working environment, and the ball valve will wear out during long-term use, causing a gap between the valve core and the valve seat, which has a wind direction for medium leakage. Utility Model Content

[0015] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0016] like Figure 1 , Figure 2 As shown, this embodiment discloses a V-shaped ball valve, including a valve body 1 and a valve core 2, the valve core 2 is rotatably installed in a channel 11 in the valve body 1 through a connecting shaft, an actuator 30 drivingly connected to the valve core 2 is also arranged on the outer wall of the valve body 1, a V-shaped opening is opened on one side of the valve core 2, a reinforcing rib 3 is arranged in the V-shaped opening of the valve core 2, a plurality of noise reduction holes 31 are arranged on the reinforcing rib 3, and a cut-off port 4 opening toward the reinforcing rib 3 is also arranged on the side wall of the valve core 2, and the medium passes through The intercepting port 4 leads to the reinforcing rib 3 after passing through, and the noise reduction hole 31 on the reinforcing rib 3 can buffer and reduce noise of the medium. A pressure plate 5, a front valve seat 6 and a rear valve seat 7 are arranged in sequence between the channel port of the valve body 1 and the valve core 2. The pressure plate 5 is connected to the valve body 1. A spring 8 is arranged between the pressure plate 5 and the front valve seat 6. The front valve seat 6 is in contact with the rear valve seat 7. The rear valve seat 7 abuts against the end face of the valve core 2 under the action of the spring 8. After the valve core 2 is worn, the spring 8 can push the rear valve seat 7 to compensate for the gap.

[0017] The reinforcing rib 3 is in a strip shape, and the noise reduction holes 31 are regularly distributed on the reinforcing rib 3. With this structure, the overall structure of the valve core 2 can be made more regular and reliable.

The actuator 30 includes a hand wheel 301, which is connected to the front shaft 10 through a worm gear. This structure makes the operation more convenient and drives the rotation of the valve core 2 more reliably.

[0019] After adopting the above technical scheme, 1. Reinforcing ribs 3 are added, so that the strength is significantly improved compared with the original one, and the phenomenon of defective products such as deformation or breakage during casting can be avoided; 2. Noise reduction holes 31 are added to the reinforcing ribs 3, which have the noise reduction function that the original ordinary V-type ball valve does not have. The noise and vibration caused by the excessive pressure difference between the medium in the pipeline and the valve body 1 can be reduced through the porous noise reduction principle, which greatly improves the stability of the product and reduces the impact of noise on the working environment; 3. The number and size of the noise reduction holes 31 on the reinforcing ribs 3 can be freely adjusted to achieve different noise reduction standards; 4. The structure is compensated by the spring 8, and there is no need to adjust the size later, which greatly reduces the installation time, improves the assembly efficiency, and makes the structure more reliable.
