Description

Lock device for pipe fittings The present invention relates to a lock device for semiconductor piping fittings, and more specifically, to a lock device for piping fittings that prevents loosening of a fitting member due to vibration of a piping line and can check whether a leak has occurred. As is well known, in semiconductor manufacturing processes, chemicals such as deionized water (DIW), sulfuric acid, phosphoric acid, hydrochloric acid, nitric acid, and hydrofluoric acid (hereinafter simply referred to as "chemical solutions") are used as cleaning agents, etching agents, and developing agents. These chemical solutions are heated to a specific temperature to enhance their chemical activity before being used in the semiconductor manufacturing process. For example, piping for supplying chemical solutions is interconnected by fittings, and these fittings may loosen due to vibration and external influences. Furthermore, prolonged use can lead to leakage as corrosion weakens the airtightness. FIG. 1 is a drawing showing a lock device for a pipe fitting according to an embodiment of the present invention. FIG. 2 is a cross-sectional view showing the state in which the lock device for pipe fitting illustrated in FIG. 1 is mounted on the pipe fitting part. Figure 3 is a planar cross-sectional view of a lock device. Figure 4 is a drawing showing a protective pad. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in describing preferred embodiments of the present invention in detail, specific descriptions of related known functions or configurations are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention. Additionally, the same reference numerals are used throughout the drawings for parts having similar functions and operations. The term 'comprising' a component means that, unless specifically stated otherwise, it does not exclude other components but rather allows for the inclusion of additional components. Specifically, terms such as "comprising" or "having" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Singular expressions include plural expressions unless the context clearly indicates otherwise. Additionally, the shapes and sizes of elements in drawings may be exaggerated for clearer explanation. Terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms may be used for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. Conversely, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between. Other expressions describing the relationships between components, such as "between" and "exactly between," or "adjacent to" and "directly adjacent to," should be interpreted in the same way. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. The above detailed description is illustrative of the present invention. Furthermore, the foregoing describes preferred embodiments of the present invention, and the present invention may be used in various other combinations, modifications, and environments. That is, modifications or alterations are possible within the scope of the concept of the invention disclosed herein, the scope equivalent to the disclosed content, and/or the scope of the art or knowledge. The described embodiments describe the best state for implementing the technical concept of the present invention, and various modifications required for specific fiel
