Problems solved by technology
[0005] Based on this, it is necessary to provide a solution for the problem that the contact area between the fluid and the upper surface of the restrictor sleeve is too large, which will increase the resistance of the fluid, reduce the flow into the valve, and further affect the overall flow and performance of the entire valve system.

Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] The embodiment of the invention discloses a pressure dispersing device. The opening end of the pressure dispersing component is fixedly arranged on the fixing device, and then the fixing device is movably linked with the inner wall of the valve. When fluid enters the valve, the fluid will change the direction of the fluid when it encounters the pressure dispersion component, and then the fluid will be introduced into the internal cavity of the pressure dispersion component through the pressure dividing hole set on the side of the pressure dispersion component, and finally the fluid will flow...

The invention relates to a pressure dispersion device. The pressure dispersion device is arranged at an inlet of a valve and is used for dispersing pressure of fluid which enters the valve on the valve. The pressure dispersion device comprises a fixing assembly and a pressure dispersion assembly, wherein the fixing assembly can be movably connected with the inner wall of the inlet of the valve; acavity is formed in the pressure dispersion assembly, the pressure dispersion assembly comprises an open end and a closed end which is opposite to the open end, the open end is fixedly connected withthe fixing assembly, an opening is formed in the cavity in the open end, and a pressure dispersion hole which communicates with the cavity is formed in the side surface of the pressure dispersion assembly. The pressure dispersion assembly is arranged in a shape of a platform, so that the resistance to the fluid is reduced, and the flow direction of the fluid is changed through the pressure dispersion hole, so that the pressure direction of the fluid on the valve is further changed, and the pressure of the fluid which enters the valve on the valve is dispersed.
Description
technical field [0001] The invention relates to the technical field of fluid control, in particular to a pressure distribution device and a valve with the pressure distribution device. Background technique [0002] In daily life, people usually transmit gaseous or liquid fluid substances such as natural gas, water, oxygen, gasoline, etc. through pipelines. While transporting through the pipeline, a valve will be set on the pipeline to adjust the flow of the pipeline to meet the needs of use. When a large flow of fluid material is required, the valve will be damaged due to the excessive pressure caused by the fluid at the valve inlet. Therefore, a barrier is usually set at the inlet of the valve to reduce the pressure of the fluid on the valve. [0003] In the current traditional technology, a restrictor sleeve is usually set in the waterway to reduce the pressure of the fluid on the valve. After the fluid enters the valve, the flow rate is reduced by first reducing the cro...
