Description

Technical Field

[0001] The utility model belongs to the field of gas valve switch keys, in particular to a valve well valve key. Background Art

[0002] The current valve key for the gas valve well usually consists of a key head, a key rod and a handle. For example, the patent document with patent announcement number CN206320396U proposes a portable gas valve switch key. The valve switch of the gas valve well is generally a square columnar structure. There is a hole corresponding to the valve switch on the key head. Since the internal space of the valve well is small, the key head needs to be installed on the key rod so that the key head can be inserted into the cylindrical enclosure to connect with the valve switch. The purpose of setting the handle is to save effort in turning the switch. However, in actual use, there will be mud around the valve switch. The valve switch is raised or covered, resulting in the valve switch not completely leaking out. The key head cannot be directly connected to the switch, so it is necessary to clean the mud first. However, due to the small space and poor light, manual cleaning is difficult. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 5A valve well valve key comprises a key head 1, a key rod 2 and a handle 3, wherein the key head 1 and the handle 3 are respectively located at two ends of the key rod 2, a sliding cavity is arranged inside the key rod 2, the sliding cavity passes through the key head 1, a sliding rod 4 is slidably arranged in the sliding cavity, the sliding rod 4 is connected to a cone rod 5, a cone head 6 is arranged at one end of the cone rod 5, a through hole 7 is arranged at the waist position of the cone head 6, a through hole 8 is arranged at the tip of the cone head 6, a channel connected with the through hole 7 and the through hole 8 is arranged inside the cone rod 5, a water pipe 9 is connected to the other end of the cone rod 5, the water pipe 9 extends from the top of the key rod 2 and is connected to a water absorber 10, a positioning rod 11 is radially connected to the upper part of the cone rod 5, a through slot 12 is opened on the key rod 2, the positioning rod 11 passes through the through slot 12, and the positioning rod 11 is connected to the key rod 2 through a locking structure.

[0021] When in use, pour water into the area around the valve switch to wet the mud, move the positioning rod 11 by hand to push out the conical head 6, hold the handle 3, use the conical head 6 to tie up the mud around the valve switch into muddy water, turn on the water absorber 10 (the water absorber can be a portable hand-pull water pump, a micro water pump or a vacuum water absorber for cleaning), the muddy water is discharged through the perforation 7 and the through hole 8 and the water pipe 9, and the purpose of cleaning is achieved. After cleaning, the conical head 6 is retracted and the key head 1 is connected to the valve switch.

[0022] A sliding cavity is arranged inside the key rod 2, the sliding cavity passes through the key head 1, a sliding rod 4 is slidingly arranged in the sliding cavity, the sliding rod 4 is connected to the cone rod 5, and a cone head 6 is arranged at one end of the cone rod 5. Water is poured into the surrounding area of ​​the valve switch to soak the soil, and then the cone head 6 is pushed out to break the soil into muddy water. Since the cone head 6 is provided with a perforation 7 and a through hole 8, and the cone rod 5 is connected to a water pipe 9, and the water pipe 9 is connected to a water absorber 10, the muddy water can be sucked out by the water absorber 10, so that the soil around the valve switch can be easily cleaned. The relevant parts for cleaning the soil are combined with the existing valve key, and there is no need to set up a rod frame separately, which is convenient for overall carrying and convenient operation. The upper part of the cone rod 5 is radially connected with a positioning rod 11, and a through slot 12 is opened on the key rod 2. The positioning rod 11 passes through the through slot 12.
