Embodiment Construction

[0032] see Figure 1-2 , is an embodiment provided by the present invention, the main technical problem solved by this embodiment is to reduce the water flow noise in the minimum flow valve, further,

[0033] Because the pump outlet minimum flow valve includes the main flow pipe 101 and the shunt pipe 501, the shunt pipe 501 is arranged on the main flow pipe 101, and the main flow pipe 101 mainly flows in and out of water to the pump, because when the main flow pipe 101 is fully opened, the shunt pipe 501 is closed, and the main flow pipe 101 The bottom is the water inlet. When the main pipe 101 is partially opened, the shunt pipe 501 is opened. When the main pipe 101 is completely closed, the shunt pipe 501 is still open, so that the pump does not stop working and ensures the normal and continuous operation of the pump; The water at the main pipe 101 at the valve is silenced, thereby reducing the water flow noise in the minimum flow valve.

[0034] see Figure 1-6 , is an e...

Abstract

The invention relates to a minimum flow valve, in particular to a pump outlet minimum flow valve. The pump outlet minimum flow valve comprises a main flow pipe and a branch flow pipe, the branch flow pipe is fixedly connected to the main flow pipe, the branch flow pipe is closed when the main flow pipe is completely opened, the branch flow pipe is opened when the main flow pipe is partially opened, and a noise reduction structure is fixedly connected into the main flow pipe. The pump outlet minimum flow valve further comprises an inner ring seat and a gate plate, the inner ring seat is fixedly connected into the main flow pipe, the gate plate is fixedly connected to the inner ring seat, and the main flow pipe is closed when the gate plate is pressed on the inner ring seat. The pump outlet minimum flow valve further comprises a round rod, a door frame and a round piece, the upper portion of the main flow pipe is fixedly connected with the door frame, the upper side of the gate plate is fixedly connected with the round rod, the round rod is vertically connected to the door frame in a sliding manner, the round rod is sleeved with a compression spring I, the compression spring I is located between the door frame and the gate plate, and the upper end of the round rod is fixedly connected with the round piece. The pump outlet minimum flow valve further comprises a circular ring and a blocking head, and the circular ring is fixedly connected to the center of the upper side of the gate plate.

Description

technical field [0001] The invention relates to a minimum flow valve, in particular to a minimum flow valve at the outlet of a pump. Background technique [0002] The minimum flow valve is generally installed on the branch pipe at the outlet of the water pump. When the water pump is in normal operation and the outer pipe supplies water, the minimum flow valve is closed. When the water pump is in normal operation and does not supply water to the outside, the pump does not stop. The minimum flow valve is controlled by one of the three methods of temperature, pressure, and outlet valve to open and close, and a part of the high-temperature water with a small flow is discharged. Prevent pump cavitation and ensure normal and continuous operation of the pump. [0003] However, when water passes inside the traditional minimum flow valve, the sound is loud, and there is no buffer for the flow of water, so the service life of the minimum flow valve cannot be increased.
