Description

Technical Field

[0001] The utility model relates to the technical field of eyewashers, in particular to a novel electric heating eyewasher and a low-temperature three-way hand-push valve thereof. Background Art

[0002] The electric heated eyewash in the prior art usually uses a welded ball valve as a hand-push valve, such as a DN15 welded ball valve or an internal thread ball valve. However, due to the space limitation of the structural design, the above ball valve is not designed with an insulation component. In winter, the hand-push valve of the electric heated eyewash can be easily frozen, causing the electric heated eyewash to be unable to be used properly. Utility Model Content

[0003] In response to the above problems, our company has developed a new type of electric heating eyewash station and its low-temperature three-way hand-push valve.

[0004] In order to solve the above technical problems, the utility model provides a new type of electric heating eyewash and a low-temperature three-way hand-push valve thereof, including an internal valve seat and a valve stem, the valve stem is connected to a valve ball placed inside the channel through a valve body neck arranged on the internal valve seat, the center height of the valve body neck is greater than 58 mm, the diameter of the valve body neck is greater than 31.5 mm, the valve stem is arranged inside the valve body neck, and an insulation layer and a sealing assembly are arranged between the valve stem and the valve body neck.

[0005] Preferably, the hand-push valve is a three-way ball valve.

[0006] Preferably, the end of the valve stem is connected to a connecting rod, and the end of the connecting rod is connected to a hand push plate.

[0007] The utility model also provides a novel electric heating eyewash, comprising an eyewash body, wherein the hand-push valve of the eyewash adopts the eyewash hand-push valve as described above.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The utility model redesigns the structure so that the hand-push valve of the application can withstand low temperatures of minus 40 degrees Celsius. The new structure can effectively prevent the hand-push valve of the electric heating eyewash from being deformed by low temperatures and causing water leakage in the eyewash valve.

[0014] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0015] Example 1

[0016] like Figure 1 and 2 As shown, a new type of low-temperature eyewash hand-push valve for electric heating eyewash includes an internal valve seat 1 and a valve stem 2. The valve stem 2 is connected to a valve ball (not shown) placed inside the channel through a valve body neck 3 provided on the internal valve seat 1. The center height of the valve body neck 3 is greater than 58 mm, and the diameter of the valve body neck 3 is greater than 31.5 mm. The valve stem 2 is provided inside the valve body neck 3, and an insulation layer is provided on the valve body neck 3. The eyewash valves of the existing electric heating eyewashes on the market all use straight-through ball valves, and there will still be accumulated water after the valve is closed, or through other structures, it will take nearly 10 seconds to drain the accumulated water, and the automatic emptying function of the eyewash tube cannot be well realized. The hand-push valve of this embodiment uses a three-way ball valve 4, which can be quickly and automatically emptied after the ball valve is closed. The end of the valve stem 2 is connected to a connecting rod, and the end of the connecting rod is connected to a hand-push plate 5.

[0017] In other specific embodiments, the center height of the valve body neck 3 can be set to 58 mm as shown in the figure, and the diameter of the valve body neck 3 is set to 31.5 mm, which is more convenient for arranging an insulation layer on the valve body neck to improve the low temperature resistance of the hand-push valve.

[0018] Example 2

[0019] This embodiment provides a novel electric heating low-temperature eyewash, including an eyewash body, wherein the hand-push valve of the eyewash adopts the eyewash hand-push valve as described above.

[0020] It should be noted here that the description of the above embodiments is only used to help understand the present invention, but does not constitute a limitation of the present invention. Technical personnel in the relevant technical field can make various changes, modifications, substitutions, integrations and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be limited by the claims.
