Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve structure with multiple valves. Background Art

[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. When in use, the water flow is generally controlled at multiple levels through the valve structure, so that the water flow size can be adjusted according to demand to facilitate the stable flow of water.

[0003] In a Chinese patent with announcement number CN217355579U, a valve structure with multiple valves is disclosed, in which a lifting rod is threadedly connected to a valve sleeve, and the valve stem passes through the inside of the lifting rod. The handle can drive the valve stem to rotate inside the valve housing, and perform linear motion while rotating, so that the plug is adjusted in the valve housing, thereby controlling the water flow through the valve housing; however, in actual use of the valve structure with multiple valves, the plug is generally controlled and adjusted by the lifting rod, but the lifting rod is exposed to the outside for a long time, which easily leads to oxidation of the lifting rod surface and rust, and the rusted lifting rod is easy to slip or difficult to rotate, so that the operator cannot rotate it quickly and stably, affecting the adjustment of the valve and reducing the adjustment efficiency of the valve.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model provides Figure 1 A multi-valve valve structure shown includes:

[0023] A valve body shell 1, a connecting disk 11 is installed on the top of the valve body shell 1, a plug 12 matching the valve body shell 1 is installed on the connecting disk 11, and the plug 12 is used to control the water flow in the valve body shell 1, a connecting rod 13 is screwed on the top of the connecting disk 11, and the connecting rod 13 and the plug 12 are fixedly connected; and a valve stem is also installed between the connecting rod 13 and the plug 12, and the structures and principles of the valve body shell 1 and the plug 12 are all prior arts, and the specific details can be referred to the comparative document (announcement number is CN217355579U, and the patent name is a valve structure with multiple valves), which will not be repeated here.

[0024] As can be seen from the above, when in use, the connecting rod 13 is rotated first, and then the connecting rod 13 is rotated along the connecting disk 11, so that the connecting rod 13 moves up and down on the connecting disk 11, and the connecting rod 13 moves the valve stem installed at its bottom end synchronously in the valve body shell 1, thereby adjusting the position between the plug 12 and the V-shaped groove installed in the valve body shell 1, so that the water flow passing through the valve body shell 1 gradually changes, thereby realizing the regulation of the water flow.

[0025] refer to Figure 1-Figure 4 As shown, the protective device 2 is used to protect the connecting rod 13. The protective device 2 includes a sleeve 22 installed on the connecting disk 11 and a protective cavity 23 provided at the bottom end of the sleeve 22 for inserting the connecting rod 13. A base 21 is fixed to the top of the connecting disk 11, and the base 21 is sleeved on the outside of the connecting rod 13. A first connecting rod 24 is installed between the sleeve 22 and the base 21. A stabilizing component 3 is provided on the sleeve 22 to fix it to the base 21. A sliding groove 25 is also provided on one side of the sleeve 22 adjacent to the protective cavity 23, and the sliding groove 25 is slidably connected to the first connecting rod 24.

[0026] The stabilizing assembly 3 includes a second connecting plate 32 fixed to the outside of the sleeve 22 and a first connecting plate 31 fixed to the outside of the base 21, a plug-in column 33 is fixed to the bottom end of the second connecting plate 32, a latch cavity for inserting the plug-in column 33 is provided at the top end of the first connecting plate 31, and a rotating assembly for installing the plug-in column 33 is provided on the first connecting plate 31; the rotating assembly includes a rotating cavity 35 provided in the first connecting plate 31 and an anti-sliding block sleeved on the outside of the plug-in column 33, and the rotating cavity 35 is communicated with the inside of the latch cavity, a bolt 34 is screwed on the first connecting plate 31, an eccentric ring 36 is sleeved on the outside of the bolt 34, and the eccentric ring 36 is located in the rotating cavity 35 and abuts against one side of the anti-sliding block.

[0027] When the connection rod 13 is adjusted, the sleeve 22 is sleeved on the outside of the connection rod 13. At this time, the connection rod 13 slides along the protective cavity 23, so that the first connection rod 24 moves into the slide groove 25, and the sleeve 22 is close to the base 21 for abutment. When the sleeve 22 moves downward, it drives the plug column 33 to be inserted into the latch cavity, so that the second connection plate 32 is pre-installed between the first connection plate 31, and the bolt 34 is rotated to make the bolt 34 threaded and rotated on the first connection plate 31, and the bolt 34 is moved up and down on the first connection plate 31, so that the bolt 34 is located in the rotation cavity 35 and moves downward. However, when the bolt 34 rotates, it drives The eccentric ring 36 rotates in the rotating cavity 35 and moves downward synchronously. As the eccentric ring 36 continues to rotate, the distance between it and the anti-sliding block is continuously reduced, and then the outer part of the eccentric ring 36 conflicts with the protective block, and then the rotation of the bolt 34 is stopped, so that the plug-in column 33 is located in the latch cavity and stably connected, which can protect the connecting rod 13 and enable the connecting rod 13 to maintain fast and stable rotation adjustment, thereby solving the problem that the existing connecting rod 13 is exposed to the outside world for a long time, which is easy to cause the surface of the connecting rod 13 to oxidize and cause rust, so as to reduce the adjustment time of the valve, improve the adjustment efficiency of the valve, and facilitate the use of the valve.

[0028] Furthermore, a rotating disk is fixed to the top of the bolt 34, and an anti-slip ring is sleeved on the outside of the rotating disk. Based on this, through the setting of the rotating disk, the rotating disk and the user's hand have a larger force-bearing area, so that the user can apply force more easily when holding and rotating, thereby increasing the torque of the outer bolt 34 when rotating, ensuring that the bolt 34 can be quickly adjusted.

[0029] In addition, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first connecting rod 24 is provided with a fine-tuning assembly 4 connecting it to the base 21, and the fine-tuning assembly 4 includes a second connecting rod 41 fixed to the top of the base 21 and an ear plate 42 fixed to the bottom end of the first connecting rod 24, and the second connecting rod 41 is consistent in size with the first connecting rod 24, and the ear plate 42 is rotatably connected to the second connecting rod 41; a movable groove 44 is also provided at the top of the second connecting rod 41, and a rotating column 43 penetrating the movable groove 44 is rotatably installed on the second connecting rod 41, and the bottom end of the ear plate 42 is inserted into the movable groove 44 and is sleeved on the outside of the rotating column 43.

[0030] When the sleeve 22 is separated from the base 21, the sleeve 22 and the base 21 are kept in a suitable position, and the sleeve 22 is pushed to drive the ear plate 42 to rotate in the movable groove 44. At this time, the rotation of the ear plate 42 drives the rotating column 43 to rotate synchronously along the movable groove 44, and then the angle of the first connecting rod 24 on the second connecting rod 41 changes, so that the connecting rod 13 is exposed, so that the angle of the sleeve 22 on the base 21 can be adjusted, and the rotation adjustment of the connecting rod 13 is convenient, which can prevent the connecting rod 13 from interfering with the sleeve 22 during adjustment, and further improve the adjustment efficiency of the valve.
