Description

Water supplementing valve and water inlet valve Technical Field The application relates to the technical field of valves, in particular to a water supplementing valve and a water inlet valve. Background A water replenishment valve is a valve device for delivering fluid, primarily for controlling the flow, pressure and direction of the fluid to ensure that the fluid in the system can be delivered and dispensed as desired. At present, in a pipeline system with a water supplementing channel, a water supplementing port is often formed at the junction of a water inlet channel, a water outlet channel and the water supplementing channel, and the water supplementing port is opened and closed by a valve core of the water supplementing valve by installing the water supplementing valve at the water supplementing port so as to realize on-off control between the water inlet channel, the water outlet channel and the water supplementing channel. When the water replenishing valve needs to be opened, the handle is rotated in one direction to be communicated with the water inlet and outlet channel and the water replenishing channel, so that the valve rod can possibly exceed the specified stroke, threads are blocked, and the sealing performance of the water replenishing valve is affected. Disclosure of utility model The application provides a water supplementing valve and a water inlet valve, which can reduce the damage of the water supplementing valve and improve the sealing performance of the water supplementing valve. In order to achieve the above purpose, the main technical scheme adopted by the application comprises the following steps: in a first aspect, an embodiment of the application provides a water supplementing valve, which comprises a first main body and a first valve rod, wherein the first main body is provided with a first hole, a first end face and a second end face, the first hole penetrates through the first end face and the second end face along the axial direction of the first hole, the first end face is perpendicular to the axis of the first hole, the first valve rod is in threaded connection with the first hole, the first valve rod is provided with a first end and a second end which are oppositely arranged along the axial direction of the first valve rod, the first end extends out of the first hole, the first end is located on one side, away from the second end face, of the first end face, a boss is arranged at the first end, protrudes out of the outer circumferential surface of the first valve rod along the radial direction of the first valve rod, and the projection of the boss at least partially overlaps with the projection of the first end face along the axial direction of the first valve rod. According to the water supplementing valve provided by the embodiment of the application, the boss protruding out of the outer peripheral surface of the first valve rod is arranged at the first end of the first valve rod, the projection of the boss and the projection of the first end face are at least partially overlapped along the axial direction of the first valve rod, when the first valve rod is retracted relative to the first hole, the boss moves towards the first end face, when the boss is abutted with the first end face, the first valve rod stops moving, the water supplementing valve is in a complete state, the boss is abutted with the first end face to limit the excessive movement of the first valve rod, the screw thread matched between the first valve rod and the first main body is reduced, the damage of the water supplementing valve is further reduced, and the sealing performance of the water supplementing valve is improved. Optionally, the water replenishing valve further comprises a handle, the handle is arranged at the second end, and the projection of the handle and the projection of the second end face at least partially overlap along the axial direction of the first valve rod. In the above scheme, the handle is arranged at the second end, and the handle is screwed to rotate the first valve rod to move in the first hole so that the first end moves towards or away from the first end surface to open or close the water supplementing valve. When the handle is screwed to the first valve rod to enable the first end to move far away from the first end face, the handle can be abutted with the second end face to limit the first valve rod to move continuously, and the water supplementing valve is in a closed state. Optionally, the boss is configured in an annular structure along a circumferential direction of the first valve stem. In the scheme, the boss of the annular structure can provide more uniform support and constraint along the circumferential direction of the first valve rod, so that shaking and offset of the valve rod in the moving process are effectively reduced, the movement of the first valve rod is more stable, the first valve rod accurately moves in a specified stroke range, the water suppleme
