A Simple One-way Valve Manual Control Structure

Abstract

The invention discloses a simple manual control structure for a one-way valve. The manual control structure comprises a one-way valve body; the top end of a one-way valve spring is clamped inside the one-way valve body by a one-way valve spring clamping spring; a one-way valve core is connected with the bottom of the one-way valve body in a manner of penetrating into the bottom of the one-way valve body; a one-way valve sealing part is arranged at the joint of the bottom of the one-way valve body and the one-way valve core; the one-way valve spring clamping spring is buckled at the top end of the one-way valve core; the bottom of the one-way valve core is connected with a one-way valve pull rod by a plastic part; one-way valve pull rod sealing parts are respectively arranged at two notches of the lower end of the one-way valve pull rod; a one-way valve button is mounted at the bottom of the one-way valve pull rod. By arranging the one-way valve button, the one-way valve spring, the one-way valve pull rod and the one-way valve core, the manual control structure disclosed by the invention can be used for opening the one-way valve and can have the effects of opening the one-way valve by pulling, filling water into a pump head so that the pump head is unblocked and opening and resetting the one-way valve; therefore, the manual control structure disclosed by the invention has the advantages of being simple in structure, convenient to operate and ideal in effect of solution.

Description

technical field [0001] The invention relates to the technical field of self-priming jet pumps, in particular to a simple one-way valve manual control structure. Background technique [0002] The self-priming jet pump is a pump body that automatically absorbs water and sprays it. It is widely used for water extraction in wells in low water level areas and household water. Because of its high head and large flow rate, it is especially suitable for water tower water supply and farmland irrigation. The tank and the pressure switch can be used as an automatic pump, which is more convenient to use. For the self-priming jet pump, a check valve needs to be installed to ensure the self-priming function, but before the pump starts, the pump head needs to be filled with water, and the single The one-way valve is an obstacle in the water filling process. The existence of the one-way valve not only makes watering difficult, but also makes it difficult to ensure full filling, which hinder...

[0002] The self-priming jet pump is a pump body that automatically absorbs water and sprays it. It is widely used for water extraction in wells in low water level areas and household water. Because of its high lift and large flow rate, it is especially suitable for water tower water supply and farmland irrigation. The tank and the pressure switch can be used as an automatic pump, which is more convenient to use. For the self-priming jet pump, a one-way valve needs to be installed to ensure the self-priming function, but before the pump starts, the pump head needs to be filled with water, while the single The one-way valve is an obstacle in the water filling process. The existence of the one-way valve not only makes watering difficult, but also makes it difficult to ensure full filling, which hinders the working effect of the pump.
