The present invention relates to a pipe assembly for a control valve that can prevent a spring from being inclined by a simple configuration. The pipe assembly includes a supply coupler, a pad, and a resilient member. The supply coupler is formed with a guide groove, with one end being mounted to a valve housing to form a flow channel through which a fluid is fed to a valve. One end of the pad encloses one end of the supply coupler, and the other end is brought into contact with the valve. The resilient member is inserted in the guide groove to press one end of the pad, thus sealing a gap between the pad and the valve. The supply coupler is preferably formed with an O-ring groove on an outer peripheral surface at one end in a circumferential direction. In this instance, the pipe assembly further includes an O-ring inserted in the O-ring groove so that the O-ring comes into contact with the pad to prevent the fluid from being discharged between the supply coupler and the pad. Since the guide groove is formed to guide the spring, the spring is prevented from being eccentrically released even if a force is applied to the spring. A washer spring or a general spring can be used as the resilient member in order to reduce a cost. |
