Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, and in particular to a highly integrated compact valve assembly. Background Technology

[0002] For example, the patent entitled "A Valve Assembly Structure with Pressure Stabilizing Function" (patent application number: CN202122290676.7) discloses a valve assembly structure with pressure stabilizing function. By adjusting the height of the first pressure regulating plate through the support column in the first cavity and the pressure reducing rubber column, the flow velocity and water pressure of the water in the valve body are adjusted, so that the water flow at the outlet of the valve body remains stable. However, in the process of closing by blocking the water flow, the water flow will generate a large impact force on the conical valve plug, which can easily lead to damage to the conical valve plug and other structures.

[0003] Therefore, it is necessary to propose a highly integrated and compact valve assembly to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a highly integrated and compact valve assembly to solve the problem that the water flow will exert a large impact force on the conical valve plug during the process of closing to prevent water flow, which can easily lead to damage to the conical valve plug and other structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly integrated compact valve assembly, including a valve body, a flow channel inside the valve body, a valve disc inside the valve body, the valve disc cooperating with the flow channel, and a first air bladder fixedly connected to the bottom end of the valve disc. When the valve disc moves downward to block the flow channel, the first air bladder expands and generates a counter-thrust force to buffer the impact of water flow.

[0006] Preferably, an annular box is provided above the valve disc, the annular box is fixedly connected to the inner wall of the valve body, the bottom end of the annular box is connected to an air pipe, the valve disc is provided with a gas channel, and the air pipe is connected to the first airbag through the gas channel.

[0007] Preferably, a slip ring is slidably disposed inside the ring box, a circular groove is formed at the bottom of the ring box, a sliding column is slidably disposed inside the circular groove, the top end of the sliding column is fixedly connected to the slip ring, and the bottom end of the sliding column is fixedly connected to the valve disc.

[0008] Preferably, the valve body is provided with a water inlet end and a water outlet end, and the water inlet end and the water outlet end are connected through a flow channel.

[0009] Preferably, the wall thickness at the bottom of the first airbag gradually increases from the water outlet end toward the water inlet end.

[0010] Preferably, a valve cover is fixedly installed on the top of the valve body, and an adjusting component is fitted on the valve cover. The bottom end of the adjusting component is rotatably connected to the valve disc.

[0011] Preferably, a handwheel is fixedly connected to the top of the adjusting member.

[0012] Preferably, a second airbag is provided below the valve disc, and the second airbag is fixedly connected to the bend of the flow channel.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a first airbag and other structures, when the valve disc moves downward to cut off the flow channel, the first airbag expands and becomes larger, and at the same time generates a counter-thrust force to unload and buffer the impact of water flow, integrating closure and protection into one, and extending the service life of the valve assembly.

[0015] 2. The wall thickness at the bottom of the first airbag gradually increases from the water outlet to the water inlet, which is designed to protect against water flow and improve the protection effect.

[0021] This utility model provides, for example Figures 1-3 The diagram shows a highly integrated compact valve assembly, comprising a valve body 1, an internal flow channel 4, an inlet 2, and an outlet 3. The inlet 2 and outlet 3 are connected via the flow channel 4. In actual use, water flows sequentially through the inlet 2, the flow channel 4, and the outlet 3.

[0022] A valve cover 5 is fixedly installed on the top of the valve body 1. An adjusting component 6 is fitted on the valve cover 5. The upper half of the adjusting component 6 is threadedly connected to the valve cover 5, and a handwheel 15 is fixedly connected to the top of the adjusting component 6. A valve disc 7 is provided inside the valve body 1. The valve disc 7 cooperates with the flow channel 4, and the bottom end of the adjusting component 6 is rotatably connected to the valve disc 7.

[0023] The valve body 1, valve cover 5, and valve disc 7 are combined to form a valve assembly structure.

[0024] Specifically, the operator rotates the adjusting component 6 by handwheel 15, which drives the valve disc 7 to move up and down. When the valve disc 7 moves down, it can block the flow channel 4, achieving a closed effect. When the valve disc 7 moves up, the flow channel 4 opens, achieving an open effect. The water can flow through the inlet end 2, the flow channel 4, and the outlet end 3 in sequence.

[0025] Considering that in actual use, when the valve disc 7 blocks the flow channel 4 and stops the water flow, the water flow will generate a large impact force on the valve disc 7, which can easily lead to a decrease in the service life of the valve assembly, in order to reduce the pressure of the valve disc 7, a first air bag 9 is fixedly connected to the bottom of the valve disc 7 to relieve the impact of the water flow.

[0026] In the specific configuration, an annular box 8 is provided above the valve disc 7, and the annular box 8 is fixedly connected to the inner wall of the valve body 1. The bottom end of the annular box 8 is connected to an air pipe 11. A gas channel 10 is provided inside the valve disc 7, and the air pipe 11 is connected to the first airbag 9 through the gas channel 10. The gas inside the annular box 8 can enter the interior of the first airbag 9 through the air pipe 11 and the gas channel 10, and the gas can also flow in the opposite direction.

[0027] To facilitate gas flow, a slip ring 12 is slidably disposed inside the annular box 8. A circular groove is provided at the bottom of the annular box 8, and a sliding column 13 is slidably disposed inside the circular groove. The top end of the sliding column 13 is fixedly connected to the slip ring 12, and the bottom end of the sliding column 13 is fixedly connected to the valve disc 7.

[0028] In actual operation, when the operator rotates the adjusting component 6 by handwheel 15, the valve disc 7 moves downward to block the flow channel 4. The valve disc 7 drives the slip ring 12 downward through the sliding column 13. The gas inside the ring box 8 enters the first air bag 9 through the air pipe 11 and the gas channel 10, causing the first air bag 9 to expand and become larger. At the same time, it generates a counter-thrust force to unload and buffer the impact of water flow. It integrates closure and protection into one, extending the service life of the valve group.

[0029] When valve disc 7 moves upward, the flow channel 4 opens, and valve disc 7 drives slip ring 12 to move upward through slip column 13. The gas inside the first air bladder 9 flows back into the ring box 8, the first air bladder 9 contracts and becomes smaller, and the subsequent water flow will act on the first air bladder 9 to continuously protect valve disc 7.

[0030] Furthermore, the ring box 8, slip ring 12 and other structures are located at the top of the valve body 1, with a compact structure that does not affect the normal use of the valve assembly.

[0031] Considering that when the water flows through the flow channel 4, it will act on the right side of the valve disc 7 due to the guiding effect of the flow channel 4 (refer to...). Figure 3 The water flow impact is greater, so to improve the protective effect, the wall thickness at the bottom of the first airbag 9 gradually increases from the water outlet 3 towards the water inlet 2. (Refer to...) Figure 3 When the gas inside the ring box 8 enters the interior of the first airbag 9 through the air pipe 11 and the gas channel 10, the wall thickness at the bottom of the first airbag 9 gradually increases from the water outlet 3 towards the water inlet 2, making the expansion of the right side of the first airbag 9 more obvious. This provides protection based on the characteristics of water flow and improves the protection effect.

[0032] A second airbag 14 is provided below the valve disc 7, and the second airbag 14 is fixedly connected to the bend of the flow channel 4. The second airbag 14 is provided to relieve pressure and buffer the water flow at the bend of the flow channel 4, further protecting the valve assembly.
