Description

Technical Field

[0001] The utility model relates to a valve cover device, specifically a special valve valve cover device with a filter, belonging to the technical field of special valves. Background Technique

[0002] Special valves are a special branch in the valve family. Their particularity lies in that they not only play the role of opening and closing, but more importantly, play the role of protecting the safety of equipment. These valves are special in design and application to meet the needs of specific industries or specific environments.

[0003] After retrieval, a valve cover disclosed in a Chinese patent with the publication number CN217301796U includes a valve cover body and a hand-twisting assembly installed on the outer wall of the valve cover body; the valve cover body includes a threaded portion connected to the valve and a rotating portion located on one side of the threaded portion and extending away from the threaded portion, and the projection of the threaded portion along the extending direction of the rotating portion is located outside the projection of the rotating portion along its own extending direction. This application has the effect of facilitating the rotation of the valve cover in a narrow space.

[0004] Although the above solution can have the effect of facilitating the rotation of the valve cover in a narrow space, the valve cover in the above patent does not have a filtering effect. Conventional valve cover devices of valves only have a single liquid-passing effect, greatly reducing their practical effect; for this reason, we provide a special valve valve cover device with a filter to solve the above problems. Content of the Utility Model

[0005] Technical Problem to be Solved

[0006] The purpose of the present utility model is to provide a special valve valve cover device with a filter to solve the problem of the lack of a filtering effect in the above-mentioned comparative document.

[0007] Technical Solution

[0008] The present utility model is realized through the following technical solutions: A special valve valve cover device with a filter includes a valve body and a valve cover body. The top of the valve body is fixedly connected to the bottom of the component protection shell. A positioning restriction pipe is fixedly arranged inside the component protection shell. A rubber water-blocking ring is fixedly arranged at the top of the positioning restriction pipe. A positioning support ring is fixedly arranged inside the positioning restriction pipe. The positioning support ring is connected to the pressure positioning ring through a positioning bolt. A first filter plate and a second filter plate are arranged between the pressure positioning ring and the positioning support ring. The tight fit between components enables the valve cover device to have a filtering effect and enhances the practical effect of the valve cover device.

[0009] Preferably, a conical connection module is fixedly arranged at the bottom of the valve cover body. The conical connection module contacts with the rubber water-blocking ring at the top of the positioning and restricting pipe. The setting of the rubber water-blocking ring can effectively avoid the liquid leakage at the joint of components.

[0010] Preferably, a special-shaped guiding disc is rotatably arranged inside the component protection housing. The special-shaped guiding disc is provided with guiding grooves. There are three groups of guiding grooves in total. The setting of the guiding grooves can effectively control other components to move along the grooving direction of the guiding grooves.

[0011] Preferably, a linkage support column is slidably arranged inside the guiding groove. A support balance plate is fixedly arranged at the top of the linkage support column. A pressing roller is rotatably arranged at one end of the support balance plate. The setting of the pressing roller can more effectively press other components, so as to keep the components stable.

[0012] Preferably, a restricting guiding disc is fixedly arranged at the top of the component protection housing. The linkage support column is slidably arranged in the groove opened on the restricting guiding disc. The setting of the linkage support column can effectively support other components and play a linkage effect.

[0013] Preferably, an external positioning grip rod is fixedly arranged on the outer circumferential surface of the special-shaped guiding disc. One end of the external positioning grip rod is fixedly connected with one end of a resilient spring. The setting of the resilient spring can effectively reset other components by using the elasticity of the resilient spring itself.

[0014] Preferably, the other end of the resilient spring is fixedly connected with one side of the positioning and clamping module. One end of the positioning and clamping module is fixedly connected with the outer circumferential surface of the component protection housing. The setting of the component protection housing can effectively protect its internal components and make its internal components not easily affected by the outside.

[0015] Preferably, there are three groups of support balance plates. Pressing rollers are respectively rotatably arranged at one ends of the three groups of support balance plates. There are three groups of pressing rollers in total. The three groups of pressing rollers all contact with the conical connection module. The setting of the conical connection module enables other components to apply a pressing force to it more conveniently through the design of its own slope.

[0016] The present utility model provides a special valve cover device with filtration, and the beneficial effects thereof are as follows:

[0017] Through the settings of the valve body, valve cover body, component protection housing, positioning and restricting pipe, rubber water-blocking ring, positioning support ring, positioning bolt, pressure positioning ring, first filter plate and second filter plate, the special valve cover device with filtration can effectively make the valve cover device have a filtration effect, enhance the practicability of the valve cover device, and at the same time facilitate the replacement of the filter plate to ensure that the filter plate is always in the best filtration effect.

[0018] The special valve cover device with filtration can effectively strengthen the bonding force between the valve and the valve cover through the settings of the conical connection module, the special-shaped guide disc, the guide groove, the linkage support column, the support balance plate, the pressure roller, the limiting guide disc, the external positioning grip, the resilient spring, and the positioning and clamping module, thus ensuring the overall stability of the valve cover device and preventing the components from falling off easily.

[0026] An embodiment of the present utility model provides a special valve cover device with filtration.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3, including a valve body 1 and a valve cover body 2. A conical connection module 11 is fixedly arranged at the bottom of the valve cover body 2. The conical connection module 11 contacts a rubber water-blocking ring 5 at the top of the positioning and restricting pipe 4. The settings of the valve cover body 2 and the conical connection module 11 can, under the action of other components, press the rubber water-blocking ring 5 by the conical connection module 11, causing the rubber water-blocking ring 5 to deform. At this time, the conical connection module 11 will contact the positioning and restricting pipe 4, enabling the setting of the rubber water-blocking ring 5, thereby ensuring that there is no liquid leakage at the junction of the conical connection module 11 and the positioning and restricting pipe 4.

[0028] Please refer to Figure 1 and Figure 2 , the top of the valve body 1 is fixedly connected to the bottom of the component protection housing 3. The setting of the component protection housing 3 can effectively support other components and exert a restricting effect, thereby ensuring the stability between components. A restricting and guiding disc 17 is fixedly arranged at the top of the component protection housing 3. A linkage support column 14 is slidably arranged in a groove formed in the restricting and guiding disc 17. The purpose of setting the restricting and guiding disc 17 is to enable the component protection housing 3 to form a relatively enclosed space, ensuring the stability of the internal components during movement. At the same time, it can effectively restrict the linkage support column 14, enabling the linkage support column 14 to slide in the groove formed in the restricting and guiding disc 17 without falling off.

[0029] Please refer to Figure 5 , a special-shaped guiding disc 12 is rotatably arranged inside the component protection housing 3. The setting of the special-shaped guiding disc 12 can effectively exert a force on other multiple groups of components, ensuring that other multiple groups of components can move synchronously. An external positioning grip 18 is fixedly arranged on the outer circumferential surface of the special-shaped guiding disc 12. The setting of the external positioning grip 18 facilitates the operation of the valve cover device by the staff.

[0030] Please refer to Figure 5 , one end of the outer circumferential surface of the external positioning grip 18 is fixedly connected to one end of a resilient spring 19. The other end of the resilient spring 19 is fixedly connected to one side of a positioning and clamping module 20. One end of the positioning and clamping module 20 is fixedly connected to the outer circumferential surface of the component protection housing 3. The settings of the external positioning grip 18, the resilient spring 19, and the positioning and clamping module 20 can utilize the elasticity of the resilient spring 19 itself to effectively pull the external positioning grip 18 to move, thereby causing the special-shaped guiding disc 12 to rotate and ensuring that the subsequent components can be in a relatively stationary state.

[0031] Please refer to Figure 5, the special-shaped guide disk 12 is provided with guide grooves 13. There are three groups of guide grooves 13 in total. A linkage support column 14 is slidably arranged inside the guide grooves 13. The purpose of setting three groups of guide grooves 13 is to enable the three linkage support columns 14 to move simultaneously and ensure that their moving speeds are consistent.

[0032] Please refer to Figure 5 , a support balance plate 15 is fixedly arranged at the top of the linkage support column 14. There are three groups of support balance plates 15 in total. Pressing rollers 16 are respectively rotatably arranged at one ends of the three groups of support balance plates 15. There are three groups of pressing rollers 16 in total. The three groups of pressing rollers 16 are all in contact with the conical connection module 11. A pressing roller 16 is rotatably arranged at one end of the support balance plate 15. The purpose of setting multiple groups of support balance plates 15 and multiple groups of pressing rollers 16 is to make the pressing rollers 16 move translationally under the cooperation of other components, gradually press the conical connection module 11, make the conical connection module 11 move downward, so as to ensure that the conical connection module 11 contacts the positioning and restricting pipe 4 and makes the rubber water blocking ring 5 deform.

[0033] Please refer to Figure 4 and Figure 5 , a positioning and restricting pipe 4 is fixedly arranged inside the component protection housing 3. A rubber water blocking ring 5 is fixedly arranged at the top of the positioning and restricting pipe 4. The rubber water blocking ring 5 has a certain elasticity. By closely contacting with the components, it can effectively block the liquid and prevent liquid leakage.

[0034] Please refer to Figure 3 and Figure 4 , a positioning support ring 6 is fixedly arranged inside the positioning and restricting pipe 4. The positioning support ring 6 is connected to the pressure positioning ring 8 through a positioning bolt 7. A first filter plate 9 and a second filter plate 10 are arranged between the pressure positioning ring 8 and the positioning support ring 6. The close cooperation among the positioning support ring 6, the positioning bolt 7 and the pressure positioning ring 8 can effectively keep the first filter plate 9 and the second filter plate 10 in a fixed state, not easy to shake, and at the same time facilitate subsequent disassembly and assembly operations.

[0035] Working principle: The first filter plate 9 and the second filter plate 10 are placed crosswise in the positioning and restricting pipe 4 and on the positioning support ring 6. At this time, the filter holes of the two will cross, enhancing the filtering effect. Then, the pressure positioning ring 8 is placed on the first filter plate 9. By externally driving the positioning bolt 7 to rotate, the pressure positioning ring 8 gradually approaches the positioning support ring 6, thereby clamping the first filter plate 9 and the second filter plate 10 to ensure their stability. Then, the valve cover body 2 is covered on the positioning and restricting pipe 4. At this time, the conical connection module 11 will contact the rubber water blocking ring 5. By externally pushing the external positioning grip 18, the special-shaped guiding disk 12 drives the guiding groove 13 to rotate in place within the component protection housing 3, changing the position of the linkage support column 14. At this time, under the restriction of the limiting guiding disk 17, the linkage support column 14 drives the pressure roller 16 on the support balance plate 15 to move horizontally, causing the pressure roller 16 to contact the conical connection module 11. Under the influence of the continuous acting force, the conical connection module 11 moves downward, squeezing the rubber water blocking ring 5, deforming the rubber water blocking ring 5. At this time, the conical connection module 11 contacts the positioning and restricting pipe 4, thus ensuring that there is no water seepage at the component connection, strengthening the connection relationship between the valve body 1 and the valve cover body 2. Under the action of the elasticity of the resilient spring 19 itself and the fact that the slotting angle of the guiding groove 13 is less than the self-locking angle, the stability of the conical connection module 11 can be ensured, thereby effectively enabling the valve cover device of this valve to have a filtering effect.
