Problems solved by technology

[0002] In the existing two-chamber water pump, the water suction chamber and the water outlet chamber are closed, and there is no connection between the low-pressure liquid and the high-pressure liquid, which makes it difficult for the water in the high-pressure water chamber to flow into the low-pressure water chamber. When we need two chambers When connecting, there will be great difficulties

Embodiment Construction

[0009] Depend on figure 1 As shown, a water outlet 7 is opened between the water suction chamber 9 and the water outlet chamber 8, and a hole coaxial with the axis of the water outlet 7 is opened on the pump body 1, and the hole is threaded with the water outlet screw body 2, And sealing ring 4 and sealing ring retaining ring 5 are housed, the passage of water suction chamber 9 and water outlet chamber 8 is controlled by drain bolt 3, and the degree of unscrewing of drain bolt 3 is controlled by stop ring 6. When the water discharge bolt 3 screwed in the water outlet 7 is tightened, the bolt head will block the water outlet 7, and the water suction chamber 9 and the water outlet chamber 8 will be closed; When the water outlet is 7, the water suction chamber 9 communicates with the water outlet chamber 8, and the water in the high-pressure water chamber flows into the low-pressure water chamber.

Abstract

The invention relates to a pump water discharge device, which belongs to the field of pump water discharge structure manufacturing. It is characterized in that: a water outlet (7) is opened between the water suction chamber (9) and the water outlet chamber (8) of the pump, and a water outlet (7) coaxial with the axis of the water outlet (7) is opened on the pump body (1). Hole, which is threaded with the drain plug body (2), and is equipped with sealing ring (4) and sealing ring retaining ring (5). The passage of water-absorbing chamber (9) and outlet chamber (8) is controlled by water discharge bolt (3), and the degree of unscrewing of water discharge bolt (3) is controlled by stop ring (6). When the water discharge bolt (3) screwed in the water outlet (7) was tightened, the bolt head blocked the water outlet (7), and the water suction chamber (9) and the water outlet chamber (8) were closed; when screwed in the water outlet ( 7) When the water discharge bolt (3) on the top is unscrewed or the water discharge port (7) is unscrewed, the water suction chamber (9) is connected with the water outlet chamber (8), and the water in the high pressure water chamber flows into the low pressure water chamber.

Description

Technical field [0001] The invention relates to a water discharge device for a water pump, which belongs to the field of pump water discharge structure manufacturing. Background technique [0002] In the existing two-chamber water pump, the water suction chamber and the water outlet chamber are closed, and there is no connection between the low-pressure liquid and the high-pressure liquid, which makes it difficult for the water in the high-pressure water chamber to flow into the low-pressure water chamber. When we need two chambers When connecting, you will encounter great difficulties. Contents of the invention [0003] The technical problem to be solved by the present invention is to avoid the deficiencies in the background technology, and to design a water discharge device for a pump, which can communicate with the water suction chamber and the water outlet chamber, and can discharge water effectively. [0004] In order to achieve the above design purpose, a water disc...
