<p>The present invention provides a service valve comprising: a body for forming a flow path for a movement of a fluid; first and second pipe connecting parts connecting first and second pipes and being connected to both sides of the flow path in the body, respectively; a valve combining part arranged to the body to form a mounting space connected to the flow path; a shutoff valve combined with the valve combining part and installed to open or close the flow path; and an injection valve arranged in the shutoff valve, for allowing the fluid to be injected to the flow path while blocking a leak of the fluid from the flow path. The shutoff valve for opening or closing a flow path of a refrigerant and a check valve for injecting the refrigerant are formed in one assembly, and, therefore, effort and costs occupied for manufacture and the size of a product are able to be reduced by reducing the number of a dividing structure of the body and the number of a combination structure of the body. It is possible to adopt a structure making it easy to disassemble or assemble the valve to reduce effect and costs occupied for maintenance and repair. Difficulties of a distinction between the valves are solved, so that everyone can easily operate a service valve. Moreover, it is easy to secure space for the operation of the valve so that a spatial limitation during installation is resolved.</p> |
