技术领域technical field
本实用新型涉及一种防锈铸铁水表壳。The utility model relates to an antirust cast iron water watch case.
背景技术Background technique
现有技术中，水表可通常由铸铁制成，但由于在长期的使用过程中，铸铁由于长时间与自来水接触，铸铁水表壳容易生锈，会对水质产生严重的二次污染而面临被淘汰。为了改善这一状况，提高水表质量，目前有一些水表壳体加工企业采用在水表壳体内表面涂覆油漆的方法来防止水表锈蚀，从而达到防止水表对水质产生二次污染的问题。虽然说这种方法在一定程度上对阻碍水表壳体的表面锈蚀起到了一定的作用，但其起作用的时间有限，油漆在水中长期浸泡下很容易失效脱落，不但不能起到防止水表壳体锈蚀，而且脱落的油漆本身更会污染水质。In the prior art, the water meter is usually made of cast iron, but due to the long-term use of cast iron due to long-term contact with tap water, the cast iron water watch case is prone to rust, which will cause serious secondary pollution to water quality and face being eliminated . In order to improve this situation and improve the quality of water meters, some water meter shell processing enterprises currently use the method of coating the inner surface of the water meter shell with paint to prevent the water meter from rusting, so as to prevent the secondary pollution of the water quality by the water meter. Although this method has played a certain role in hindering the surface corrosion of the water meter casing to a certain extent, its working time is limited. The paint is easy to fail and fall off under long-term immersion in water, and it cannot prevent the corrosion of the water meter casing. Corrosion, and the peeling paint itself will pollute the water quality.
发明内容Contents of the invention
本实用新型针对现有技术中的不足，提供了一种结构简单、使用过程对水质无二次污染，使用寿命长的防锈铸铁水表壳。Aiming at the deficiencies in the prior art, the utility model provides a rust-proof cast iron water watch case with a simple structure, no secondary pollution to the water quality in the use process, and a long service life.
为了解决上述技术问题，本实用新型通过下述技术方案得以解决：In order to solve the above technical problems, the utility model is solved through the following technical solutions:
一种防锈铸铁水表壳，包括铸铁壳体，所述壳体的内表面上涂覆有表面光滑且附着力高的防护层。本实用新型依然采用铸铁为主要原料，使其成本控制在较低水平，同时由于在壳体的内表面涂覆的防护层能有效防止铸铁壳体与自来水的直接接触，从而避免了铸铁壳体受到氧化，从而大大延长了本实用新型的使用寿命；其次，由于防护层与自来水不会产生反应，且不易脱落，因此，也避免了本实用新型对水质产生二次污染；再次，由于防护层表面光滑，所以不容易结垢、粘污。An antirust cast iron water watch case comprises a cast iron casing, the inner surface of the casing is coated with a protective layer with smooth surface and high adhesion. The utility model still uses cast iron as the main raw material, so that its cost is controlled at a relatively low level. At the same time, the protective layer coated on the inner surface of the shell can effectively prevent the direct contact between the cast iron shell and tap water, thus avoiding the cast iron shell Oxidation greatly prolongs the service life of the utility model; secondly, because the protective layer does not react with tap water and is not easy to fall off, the utility model also avoids secondary pollution of water quality; again, because the protective layer The surface is smooth, so it is not easy to scale and stick to dirt.
优选的方案之一：上述防护层为釉质层。One of the preferred schemes: the protective layer is an enamel layer.
优选的方案之二：上述防护层为特氟龙。The second preferred solution: the protective layer is Teflon.
优选的方案之三：上述防护层为粉末涂层。The third preferred solution: the protective layer is a powder coating.
优选的，上粉末涂层为环氧类粉末涂层或聚酯粉末涂层。Preferably, the upper powder coating is epoxy powder coating or polyester powder coating.
本实用新型与现有技术相比，具有如下有益效果：Compared with the prior art, the utility model has the following beneficial effects:
1)铸铁壳体的内表面涂覆的防护层能有效防止铸铁壳体与自来水的直接接触，从而避免了铸铁壳体受到氧化，从而大大延长了本实用新型的使用寿命；1) The protective layer coated on the inner surface of the cast iron shell can effectively prevent the direct contact between the cast iron shell and tap water, thereby avoiding the cast iron shell from being oxidized, thereby greatly prolonging the service life of the utility model;
2)由于防护层与自来水不会产生反应，因此，也避免了本实用新型对水质产生二次污染。2) Since the protective layer does not react with tap water, the utility model also avoids secondary pollution of water quality.
3)由于防护层表面光滑，所以不容易结垢、粘污。3) Since the surface of the protective layer is smooth, it is not easy to scale and stick to dirt.
4)由于本实用新型依然采用铸铁为主要原料，使其成本控制在较低水平。4) Since the utility model still adopts cast iron as the main raw material, its cost is controlled at a lower level.
