Description

Technical Field

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

[0002] In winter, many water outlet pipe valves installed outdoors are easily frozen because the water in the valves stops flowing at night due to water incompatibility, which affects their use and even causes cracks, resulting in unnecessary losses. The frozen areas need to be thawed, and some areas even need valves replaced. Therefore, a valve casting that can solve the antifreeze problem is needed.

[0003] After searching, it is found that a Chinese patent document discloses an antifreeze valve casting [application number: CN202321191963.5]. This antifreeze valve casting includes a valve, the outer wall of the valve is sleeved with an antifreeze shell, the outer wall of the antifreeze shell is fixedly connected to a fixing plate, and the internal thread of the fixing plate is connected to a bolt. The inner wall of the antifreeze shell is fixedly installed with a waterproof insulation layer, the inner wall of the waterproof insulation layer is fixedly installed with a heating wire, the inner side of the heating wire is fixedly installed with a heat conductive layer, the outer wall of the antifreeze shell is fixedly installed with a battery box, and the bottom of the antifreeze shell is fixedly connected with a rotating plate.

[0004] When the device disclosed in this patent is in use, the antifreeze shells on both sides are used to isolate the outside air, thereby improving the antifreeze ability of the valve. However, in this way, when there is a problem with the valve, the staff needs to remove the antifreeze shells on both sides before repairing it, which is inconvenient to use. In addition, the controller of the valve is exposed, and the outside temperature can enter the pipeline and valve through the controller, which will affect the antifreeze effect of the valve.

Closable antifreeze boxes 7 are arranged on both sides of the surface of the moving mechanism 6, and an auxiliary mechanism 8 is arranged on the surface of the antifreeze box 7 on one side. When the utility model is in use, it can play an antifreeze effect under the action of the antifreeze box 7. If the staff needs to repair or maintain the antifreeze valve 2, the staff can use the moving mechanism 6 to move and separate the antifreeze boxes 7 on both sides to facilitate the staff to repair it. In addition, under the action of the auxiliary mechanism 8, the antifreeze valve 2 can be operated without exposing the antifreeze valve 2, thereby avoiding direct contact between the antifreeze valve 2 and the outside world to affect the antifreeze effect.

[0022] The moving mechanism 6 includes a rotating rod 62 that rotates in the inner cavity of the connecting blocks 3 on both sides, a rotating block 61 is fixed to one end of the rotating rod 62, and threaded bodies 63 are arranged on both sides of the surface of the rotating rod 62. The surface of the threaded body 63 is meshed with an engaging block 64, and the engaging blocks 64 on both sides are respectively fixed to the surface of the antifreeze box 7. In this embodiment, through the arrangement of the rotating block 61, the rotating rod 62, the threaded body 63 and the engaging block 64, the staff can use the rotating block 61. Under the action of the rotating block 61, the rotating rod 62 drives the threaded bodies 63 on both sides to rotate, and the engaging block 64 meshed with the threaded body 63 can drive the antifreeze box 7 to move.

[0023] The thread directions of the threaded bodies 63 on both sides are opposite but the specifications are the same, and the thread lead angle of the threaded body 63 is smaller than the equivalent friction angle. In this embodiment, through this setting, when the antifreeze boxes 7 on both sides move, the directions are opposite but the distances are the same, and under the setting of the specifications of the threaded body 63, the threaded body 63 has self-locking properties.

[0024] The auxiliary mechanism 8 includes a connecting rod 82 that slides on the surface of the antifreeze box 7 on one side, a pressing head 81 is fixed at one end of the connecting rod 82, a limit block 84 is rotatably arranged on the surface of the connecting rod 82, a spring 85 is fixed on the surface of the limit block 84, a fixing block 86 is fixed on the other end of the spring 85, and the fixing block 86 is fixed to the surface of the antifreeze box 7, and a plurality of driving rods 83 are fixed on the other end of the connecting rod 82. In this embodiment, through the setting of the pressing head 81, the connecting rod 82, the driving rod 83, the limit block 84, the spring 85 and the fixing block 86, the staff can press the pressing head 81, and then, driven by the connecting rod 82, the driving rod 83 is inserted into the gap of the control part of the antifreeze valve 2. If the gap between the driving rod 83 and the control part cannot be aligned, the staff can rotate the pressing head 81. After the driving rod 83 is inserted, the staff can rotate the pressing head 81 to make the driving rod 83 drive the controller to rotate.

In this embodiment, through the provision of the sealing ring 5, the sealing effect between the antifreeze boxes 7 on both sides is improved after the antifreeze boxes 7 on both sides are fitted together.

[0027] Working principle: In daily use, by closing the antifreeze boxes 7 on both sides, the effect of isolating the external cold air can be achieved. If the controller of the antifreeze valve 2 needs to be rotated, the staff can press the pressing head 81 to insert the driving rod 83 into the gap of the antifreeze valve 2 controller. If the driving rod 83 cannot be inserted, the staff can rotate the pressing head 81. After insertion, the staff allows the pressing head 81 to rotate the driving rod 83 through the connecting rod 82, thereby achieving the effect of controlling the antifreeze valve 2. In addition, if the antifreeze valve 2 needs to be repaired or maintained, the staff can use the rotating block 61. Under the action of the rotating block 61, the threaded body 63 and the engaging block 64 are engaged, so that the engaging blocks 64 on both sides drive the corresponding antifreeze boxes 7 to move, so that the antifreeze boxes 7 on both sides are separated, and the antifreeze valve 2 is exposed, which is convenient for the staff to repair or maintain it.
