Description

Compact valve group with high integration Technical Field The utility model relates to the technical field of valve groups, in particular to a high-integration compact valve group. Background For example, a valve group structure with pressure stabilizing effect (patent application number: CN 202122290676.7) is disclosed in the patent with pressure stabilizing effect, the height of the first pressure regulating plate is adjusted by the support column in the first cavity matched with the pressure reducing rubber column, the flow speed and the water pressure of water flow in the valve body are adjusted, so that the water flow at the water outlet of the valve body is kept in a stable state, but in the process of stopping the water flow and closing, the water flow can generate larger impact force on the conical valve plug, and the structures such as the conical valve plug are easy to damage. Therefore, it is necessary to provide a compact valve block with high integration to solve the above problems. Disclosure of utility model The utility model aims to provide a high-integration compact valve group so as to solve the problem that the conical valve plug and other structures are easy to damage due to the fact that the water flow can generate larger impact force on the conical valve plug in the process of blocking the water flow to be closed. In order to achieve the purpose, the high-integration compact valve bank comprises a valve body, wherein a circulation channel is arranged in the valve body, a valve clack is arranged in the valve body and matched with the circulation channel, a first air bag is fixedly connected to the bottom end of the valve clack, and when the valve clack moves downwards to partition the circulation channel, the first air bag expands to be large and generates a reverse thrust for unloading and buffering water flow impact. Preferably, a ring box is arranged above the valve clack, the ring box is fixedly connected to the inner wall of the valve body, the bottom end of the ring box is communicated with an air pipe, a gas channel is arranged in the valve clack, and the air pipe is communicated with the first air bag through the gas channel. Preferably, the inside slip of ring box is provided with the sliding ring, the circular slot has been seted up to the bottom of ring box, and the inside slip of circular slot is provided with the traveller, the top fixed connection of traveller is on the sliding ring, the bottom fixed connection of traveller is on the valve clack. Preferably, the valve body is provided with a water inlet end, the valve body is provided with a water outlet end, and the water inlet end is communicated with the water outlet end through a flow channel. Preferably, the wall thickness at the bottom end of the first air bag gradually increases from the water outlet end to the water inlet end. Preferably, a valve cover is fixedly arranged at the top of the valve body, an adjusting piece is matched on the valve cover, and the bottom end of the adjusting piece is rotationally connected with the valve clack. Preferably, the top of the adjusting piece is fixedly connected with a hand wheel. Preferably, a second air bag is arranged below the valve clack, and the second air bag is fixedly connected to the bent part of the circulation channel. The utility model has the technical effects and advantages that: 1. According to the utility model, by arranging the structures such as the first air bag and the like, when the valve clack moves downwards to separate the circulation channel, the first air bag expands and becomes larger, and meanwhile, counter thrust is generated, so that the impact of water flow is relieved and buffered, the closing and the protection are integrated, and the service life of the valve group is prolonged; 2. The thickness of the wall body at the bottom end of the first air bag gradually increases from the water outlet end to the water inlet end, and the protection is performed according to the flow characteristics of water flow, so that the protection effect is improved; 3. And a second air bag is arranged, so that the force-unloading buffer is carried out on the water flow at the bending part of the circulation channel, and the valve group is further protected.
