Abstract
The utility model provides a self-locking electric water heater safety valve which comprises a valve body and a handle, wherein the handle is fixedly connected to the rear end of the valve body through a bolt, the tail end of the bolt is screwed into a screw hole of the valve body, and the middle section of the bolt is clamped in a through hole of the handle. The utility model has the advantages that: the structure design is reasonable, the bolt connecting the valve body and the handle is not easy to fall off, the handle is ensured to be firmly connected on the valve body, the safety and the reliability are realized, the accident is avoided, and the service life of the safety valve is prolonged.
Description
Technical Field
The utility model relates to the technical field of safety valves, in particular to a self-locking electric water heater safety valve.
Background
The safety valve as one kind of protector has the main operation principle of automatic pressure relief when the tap water pressure is higher than the rated pressure of the inner container of the electric water heater. In the existing safety valve, a handle at the tail end of a valve body is fastened with the valve body through bolts, and the bolts are clamped in screw holes in the valve body. However, in the use process of the safety valve, the bolts are easy to loosen and slide out of the valve body due to vibration and other reasons, so that the handle is separated, and serious safety accidents are caused.
Disclosure of Invention
The utility model aims to provide a self-locking electric water heater safety valve which is reasonable in structural design, is not easy to fall off a connecting bolt, and is safe and reliable.
In order to achieve the above purpose, the present utility model is realized by the following technical scheme:
the utility model provides a self-locking electric water heater relief valve, includes valve body and handle, and the handle passes through bolted connection to be fixed in the valve body rear end, and the bolt end screws in the screw of valve body, the bolt middle section chucking is in the through-hole of handle.
Further, the aperture of the through hole of the handle is gradually decreased from outside to inside, and the aperture of the innermost end of the through hole is consistent with the pitch diameter of the bolt.
Compared with the prior art, the utility model has the following advantages:
the self-locking type safety valve for the electric water heater has reasonable structural design, the bolt connecting the valve body and the handle is not easy to fall off, the handle is ensured to be firmly connected to the valve body, the safety valve is safe and reliable, accidents are avoided, and the service life of the safety valve is prolonged.
Drawings
Fig. 1 is a schematic diagram of the overall structure of a self-locking electric water heater safety valve according to the present utility model.
Fig. 2 is a schematic view of a prior art handle through hole and bolt connection structure.
Fig. 3 is a schematic view of the structure of the through hole and bolt connection of the handle of the present utility model.
Reference numerals: 1. a valve body; 2. a handle; 3. a bolt; 4. and a clamping structure.
Description of the embodiments
Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings.
As shown in fig. 2, the aperture of the through hole of the existing handle is consistent with the outer diameter of the bolt, and the bolt passes through the through hole of the handle and is fastened in the screw hole at the rear end of the valve body. In the use process of the safety valve, the structure easily causes loosening of the bolt and sliding out of the valve body due to vibration and other reasons, so that the handle is separated, and serious safety accidents are caused.
As shown in fig. 1 and 3, a self-locking safety valve for electric water heater comprises a valve body 1 and a handle 2, wherein the handle 2 is fixedly connected with the rear end of the valve body 1 through a bolt 3, the tail end of the bolt 3 is screwed into a screw hole of the valve body 1, the middle section of the bolt 3 is clamped in a through hole of the handle 2, namely, a clamping structure 4 is additionally arranged at the through hole of the handle 2 by the bolt 3, so that the accident that the handle 2 is separated due to the fact that the bolt 3 is not easy to loosen and slide out of the valve body 1 is ensured. Specifically, the aperture of the through hole of the handle 2 is gradually decreased from outside to inside, the diameter of the outermost end of the through hole is slightly larger than the outer diameter of the bolt 3, and the diameter of the innermost end of the through hole is consistent with the middle diameter of the bolt 3. The bolt 3 is screwed into a screw hole at the rear end of the valve body 1, and the through hole structure of the handle 2 is designed to be additionally provided with a safety; if the bolt 3 is slightly separated from the screw hole of the valve body 1 in the use process of the safety valve, the handle 2 is slightly separated from the valve body 1, and at the moment, the outer section (thicker section) of the bolt 3 further stretches into the through hole of the handle 2 in the relative movement of the handle 2 and the bolt 3, so that the bolt 3 is clamped in the through hole of the handle 2, the handle 2 is ensured not to be further separated from the valve body 1, and the handle 2 is still connected with the valve body 1 relatively stably.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the concept of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
