[0001] The utility model belongs to the technical field of valve manufacturing, and particularly relates to an exhaust plug. Background Art

[0002] An exhaust plug is an auxiliary device specifically used to remove air bubbles.

[0003] When the exhaust plug is in use, there is a lack of sealing components on it, and water leakage will occur during the use process, resulting in waste of water resources and increased use costs. Therefore, in order to solve such problems, we propose an exhaust plug. Summary of the Invention

[0004] The purpose of the utility model is to provide an exhaust plug with relatively high sealing performance for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: An exhaust plug includes a joint. A valve body is inlaid at the top of the joint. A valve rod is inlaid on the inner wall of the joint. The top of the valve rod penetrates to the top of the valve body. A handwheel is sleeved on the top of the valve rod. An O-ring I is sleeved outside the joint. An O-ring II is sleeved between the bottom of the valve rod and the inner wall of the joint. An O-ring III is sleeved between the middle of the valve rod and the inner wall of the valve body.

[0006] Through the cooperation of the joint, the valve rod, the valve body, the handwheel, the O-ring I, the O-ring II and the O-ring III, the exhaust plug has relatively high sealing performance, solves the problems of water leakage causing waste of water resources and increased costs, as well as high requirements for sealing performance and time-consuming and laborious installation process affecting the working efficiency of equipment.

[0007] In the above-mentioned exhaust plug, an installation screw hole is opened on one side of the top of the handwheel. A connecting stud is threadedly connected to the inner wall of the installation screw hole. The top of the connecting stud is connected with a push rod. Through the cooperation of the installation screw hole and the connecting stud, it is convenient to install the push rod on the handwheel.

[0008] In the above-mentioned exhaust plug, a bearing is sleeved at the center of the outside of the handwheel. An indicating disk is sleeved outside the bearing. Both sides of the bottom of the indicating disk are connected with L-shaped frames. The side of the L-shaped frame away from the handwheel is connected with the valve body. Through the bearing, it is convenient for the indicating disk to be movably sleeved outside the handwheel.

[0009] In the above-mentioned exhaust plug, a plurality of scale grooves are opened on the outside of the top of the indicating disk. An indicating needle is connected to one side of the outside of the handwheel and is used in cooperation with the scale grooves. Through the cooperation of the scale grooves and the indicating needle, it is convenient to know the rotation angle of the handwheel.

[0010] Compared with the prior art, through the cooperation of the joint, valve rod, valve body, handwheel, O-ring I, O-ring II and O-ring III, this exhaust plug has high sealing performance, solves the problems of water leakage causing waste of water resources and increased costs, as well as the problems of high requirements for sealing performance and time-consuming and laborious installation process affecting the working efficiency of equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic structural diagram of the present utility model.

[0012] Figure 2 It is a top view of the structural cooperation of the handwheel and the indicating disk of the present utility model.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0015] As Figure 1 and Figure 2 shown, this exhaust plug includes a joint 1, the top of the joint 1 is inlaid with a valve body 3, the inner wall of the joint 1 is inlaid with a valve rod 2, the top of the valve rod 2 penetrates to the top of the valve body 3, the top of the outer part of the valve rod 2 is sleeved with a handwheel 4, the outer part of the joint 1 is sleeved with an O-ring I 5, an O-ring II 6 is sleeved between the bottom of the outer part of the valve rod 2 and the inner wall of the joint 1, and an O-ring III 7 is sleeved between the middle of the outer part of the valve rod 2 and the inner wall of the valve body 3.

[0016] During actual manufacturing, a mounting screw hole 14 is opened on one side of the top of the handwheel 4, the inner wall of the mounting screw hole 14 is threadedly connected with a connecting stud 10, and the top of the connecting stud 10 is connected with a push rod 11.

[0017] During actual manufacturing, a bearing 13 is sleeved at the center of the outer part of the handwheel 4, an indicating disk 12 is sleeved on the outer part of the bearing 13, both sides of the bottom of the indicating disk 12 are connected with an L-shaped bracket 8, and the side of the L-shaped bracket 8 away from the handwheel 4 is connected with the valve body 3.

[0018] During actual manufacturing, a plurality of scale grooves 15 are opened on the outer side of the top of the indicating disk 12, and an indicating needle 9 which is matched with the scale grooves 15 is connected to one side of the outer part of the handwheel 4.

[0019] When the utility model is in use, through the cooperation of the joint 1, the valve rod 2, the valve body 3, the handwheel 4, the first O-ring 5, the second O-ring 6 and the third O-ring 7, it has high sealing performance, solves the problems of water leakage causing waste of water resources and increased costs, as well as high requirements for sealing performance and time-consuming and laborious installation process affecting the working efficiency of the equipment. If it is necessary to rotate the valve rod 2, the handwheel 4 can be directly rotated. The handwheel 4 drives the valve rod 2 to rotate. At this time, the indicating needle 9 rotates with the handwheel 4. With the cooperation of the scale groove 15, it is convenient to know the rotation angle of the handwheel 4 and the valve rod 2. If the handwheel 4 is rotated, the friction force between the staff's palm and the handwheel 4 is small and the handwheel 4 cannot be effectively rotated. At this time, the push rod 11 can be pushed to achieve the purpose of rotating the handwheel 4.
