Embodiment Construction

[0015] see figure 1 , an automatic flushing valve for a sewage pump of the present invention is provided with a valve body 2, and a valve flow channel and a valve ball chamber 19 are arranged in the valve body 2; and regulator. The whole flushing valve is installed on the volute of the sewage pump by screws, and the water inlet pipe 1 of the flushing valve communicates with the water outlet on the pump casing.

[0016] The valve flow channel in the valve body 2 is formed by connecting the large-area inlet cavity 3, the small-area valve cavity 4, the valve seat 5 and the spray pipe 6 in sequence. The water outlet on the pump casing communicates with the large-area inlet 3. Spray pipe 6 inlet ends in the valve flow path are installed valve seat 5, and the nozzle pipe 6 outlet ends in the valve flow path can be installed elbow 7, and bend pipe 7 can be rotated 360 ° after putting on.

[0017] The valve ball chamber 19 is arranged below the valve flow passage, that is, below th...

Abstract

An automatically washing valve used on pollution discharging pump is prepared as forming valve runner by connecting inlet cavity and valve cavity as well as jet tube in sequence, setting valve ball chamber under valve runner and setting valve ball and ball bearing in it, setting ball bearing on bowl diaphragm to support valve ball, forming top oil bag by corrugated rubber tube and recovery hammer as well as top cover, forming bottom oil bag by bowl diaphragm and bottom cover, setting nozzle and one-way valve as well as regulation valve in body of regulator.

Description

technical field [0001] The invention relates to a pump valve, in particular to an automatic opening and closing flushing valve installed on a sewage pump. Background technique [0002] At present, for the recoil stirring of the sewage pump inlet pool or the water inlet well to prevent sedimentation and deposition, a sewage pump with a stirring function is used. Although it can stir evenly during recoil, it can only disturb the pool or well in a small range. The effect is small, and when the recoil is not needed, the water is still sprayed and stirred, thus wasting the energy and power of the pump. Contents of the invention [0003] The task of the present invention is to provide an automatic flushing valve for a sewage pump, which solves the problem that the sewage pump in the prior art can only be disturbed in a small range during recoil, its effect is small, and the energy and power of the pump are wasted. [0004] Technical scheme of the present invention is as follows...
