Technical Field
[0001] This utility model relates to the field of valve technology, specifically to an energy-saving and environmentally friendly valve device. Background Technology
[0002] A valve is a device used to control the flow of fluids (such as liquids, gases, slurries, etc.) in pipes or equipment, thereby changing the direction of fluid flow and cutting it off.
[0003] Valves are typically composed of components such as valve body, valve cover, opening and closing parts (such as valve core and valve disc), and drive mechanism (such as handle, gear, and motor). They are widely used in many fields such as petroleum, chemical, water conservancy, power and municipal engineering, and are indispensable control elements in fluid transportation systems.
[0004] Traditional valve devices are typically made of metal to ensure normal operation. While these valves have a long service life, their connections with other pipelines are usually sealed with gaskets. These gaskets are easily eroded by liquids or deformed due to liquid corrosion and aging, resulting in poor sealing and leakage. This leads to liquid loss and is detrimental to energy conservation and environmental protection. Utility Model Content

The inner end of the threaded sleeve is threaded and engaged with the outer side of the valve body. A protective component is provided inside the connecting end near the threaded sleeve, and the protective component includes expanded graphite fixedly connected to the inner side of the connecting end near the threaded sleeve. Polytetrafluoroethylene (PTFE) is fixedly connected to the expanded graphite on the side away from the connecting end, and the PTFE on the side away from the expanded graphite is fitted with the threaded sleeve and the valve body. A snap-fit component is provided at the outer end of the PTFE on the side away from the expanded graphite, and a sealing component is provided at the end of the snap-fit component away from the PTFE. An elastic component is provided on the outer side of the valve body near the connecting end, and a locking component is provided at the end of the elastic component near the threaded sleeve.
[0007] As a preferred embodiment of the above technical solution, the snap-fit assembly includes a fixing plate fixedly connected to the outer end of the polytetrafluoroethylene (PTFE) away from the expanded graphite, and a first insert plate is inserted into the inner end of the fixing plate away from the PTFE. The fixing plate and the first insert plate are inserted into the valve body.
[0008] As a preferred embodiment of the above technical solution, the sealing assembly includes a nitrile rubber fixedly connected to the end of the first insert plate away from the fixed plate, and a rubber sealing sleeve fixedly connected to the end of the nitrile rubber away from the first insert plate.
[0009] The above technical solution involves sealing the connection between the valve body and the threaded sleeve using nitrile rubber and a rubber sealing sleeve.
[0010] As a preferred embodiment of the above technical solution, the nitrile rubber and the rubber sealing sleeve are fitted and wrapped around the outside of the fixing plate and the first insert plate.
[0011] As a preferred embodiment of the above technical solution, the elastic component includes a baffle fixedly connected to the outer side of the valve body near the threaded sleeve, and a positioning cylinder fixedly connected to the side of the baffle near the threaded sleeve. A rod is inserted into the positioning cylinder at the end away from the baffle, and a spring is sleeved on the outer side of the positioning cylinder and the rod.

A second insertion plate is fixedly connected to the end of the push plate away from the insertion rod.
[0013] The above technical solution involves inserting a second insert plate into the threaded sleeve to restrict its movement.
[0014] As a preferred embodiment of the above technical solution, five sets of second insert plates are arranged in a circumferential array on the push plate, and the end of the second insert plate away from the push plate is inserted into the threaded sleeve.
[0015] Compared with the prior art, the beneficial effects of this utility model are: This energy-saving and environmentally friendly valve device can improve the sealing stability of the connection end when the valve body and the connection end are assembled by using protective components and snap-fit components, thereby avoiding liquid loss caused by poor sealing effect and thus improving energy saving and environmental protection effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an energy-saving and environmentally friendly valve device, including a valve body 1, with connecting ends 11 at both ends of the valve body 1. A threaded sleeve 12 is fixedly connected to the outer end of the connecting end 11 near the valve body 1. The inner end of the threaded sleeve 12 is threaded onto the outer side of the valve body 1. A protective component 2 is provided inside the connecting end 11 near the threaded sleeve 12. The protective component 2 includes expanded graphite 21 fixedly connected to the inner side of the connecting end 11 near the threaded sleeve 12. A polytetrafluoroethylene (PTFE) 22 is fixedly connected to the side of the expanded graphite 21 away from the connecting end 11. The side of the PTFE 22 away from the expanded graphite 21 is fitted against the threaded sleeve 12 and the valve body 1. The outer end of the side of the PTFE 22 away from the expanded graphite 21 is... The valve body 1 has a snap-fit component 3, and a sealing component 4 is provided at the end of the snap-fit component 3 away from the polytetrafluoroethylene 22. A spring component 5 is provided on the outer side of the valve body 1 near the connecting end 11, and a locking component 6 is provided at the end of the spring component 5 near the threaded sleeve 12. When the valve body 1 and the connecting end 11 are assembled together by the cooperation of the protective component 2 and the snap-fit component 3, the sealing stability of the connecting end can be improved, and liquid loss caused by poor sealing effect can be avoided, thereby improving energy saving and environmental protection effect.
[0020] like Figure 3 As shown, the snap-fit assembly 3 includes a fixing plate 31 fixedly connected to the outer end of the polytetrafluoroethylene 22 away from the expanded graphite 21, and a first insert plate 32 is inserted inside the fixing plate 31 at the end away from the polytetrafluoroethylene 22. The fixing plate 31 and the first insert plate 32 are inserted into the valve body 1. The nitrile rubber 41 and the rubber sealing sleeve 42 drive the first insert plate 32 to be sleeved on the outside of the fixing plate 31, and the first insert plate 32 is inserted into the fixing plate 31.
[0021] like Figure 3As shown, the sealing assembly 4 includes a nitrile rubber 41 fixedly connected to the end of the first insert plate 32 away from the fixed plate 31, and a rubber sealing sleeve 42 fixedly connected to the end of the nitrile rubber 41 away from the first insert plate 32. The valve body 1 is simultaneously driven by the fixed plate 31 and the first insert plate 32 to insert the nitrile rubber 41 and the rubber sealing sleeve 42 into the valve body 1 for installation.
[0022] like Figure 3 As shown, nitrile rubber 41 and rubber sealing sleeve 42 are fitted and wrapped around the outside of the fixing plate 31 and the first insert plate 32.
[0023] like Figure 2 As shown, the elastic component 5 includes a baffle 51 fixedly connected to the outer side of the valve body 1 near the threaded sleeve 12, and a positioning cylinder 52 fixedly connected to the side of the baffle 51 near the threaded sleeve 12. A rod 53 is inserted into the end of the positioning cylinder 52 away from the baffle 51, and a spring 54 is sleeved on the outer side of the positioning cylinder 52 and the rod 53. The end of the spring 54 near the baffle 51 is fixedly connected to the baffle 51.
[0024] like Figure 1 As shown, the locking assembly 6 includes a push plate 61 fixedly connected to the end of the insertion rod 53 away from the positioning cylinder 52, and a spring 54 fixedly connected to the end of the push plate 61 away from the baffle 51. A second insertion plate 62 is fixedly connected to the end of the push plate 61 away from the insertion rod 53. Pushing the push plate 61 compresses the spring 54 under the restriction of the insertion rod 53 and the positioning cylinder 52. After the threaded sleeve 12 is screwed in, the pulled push plate 61 is released. At this time, the elastic potential energy of the spring 54 pushes the push plate 61 and the second insertion plate 62 to move, so that the second insertion plate 62 is inserted into the threaded sleeve 12 to lock and restrict the threaded sleeve 12.
[0025] like Figure 1 As shown, five sets of second insert plates 62 are arranged in a circumferential array on the push plate 61, and the end of the second insert plate 62 away from the push plate 61 is inserted into the threaded sleeve 12.
[0026] Working principle: When assembling the valve body 1 and the connecting end 11, firstly, the nitrile rubber 41 and the rubber sealing sleeve 42 drive the first insert plate 32 to be fitted onto the outside of the fixed plate 31, and the first insert plate 32 is inserted into the fixed plate 31. Then, the connecting end 11 drives the threaded sleeve 12 to be fitted and screwed into the outside of the valve body 1. When the threaded sleeve 12 is screwed in, the valve body 1, with the assistance of the fixed plate 31 and the first insert plate 32, simultaneously drives the nitrile rubber 41 and the rubber sealing sleeve 42 to be inserted into the valve body 1 for installation. Before the threaded sleeve 12 is about to be fitted and screwed in, first push the pusher... Plate 61 compresses the spring 54 under the constraint of the insert rod 53 and the positioning cylinder 52. After the threaded sleeve 12 is screwed in, the pulled push plate 61 is released. At this time, the elastic potential energy of the spring 54 pushes the push plate 61 and the second insert plate 62 to move, so that the second insert plate 62 is inserted into the threaded sleeve 12 to lock and restrict the threaded sleeve 12, preventing the threaded sleeve 12 from rotating in the future. In subsequent use, the connection end of the valve body 1 and the connection end 11 is sealed by expanded graphite 21, polytetrafluoroethylene 22, nitrile rubber 41 and rubber sealing sleeve 42.
[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
