Abstract
The invention relates to a water drainage device for a pump, and belongs to the field of water drainage structures for pumps. The water drainage device is characterized in that: a water drainage port (7) is formed between a water absorption cavity (9) and a water outlet cavity (8) of the pump, the pump body (1) is provided with a hole coaxial with the water drainage port (7), the hole is in threaded connection with a water drainage plug screw body (2), and the pump body (1) is provided with a sealing ring (4) and a sealing ring stopper (5). Connection and disconnection of the water absorption cavity (9) and the water outlet cavity (8) are controlled by a water drainage bolt (3), and the unscrewing degree of the water drainage bolt (3) is controlled by a stop ring (6). When the water drainage bolt (3) screwed in the water drainage port (7) is screwed, the head of the bolt blocks the water drainage port (7), and the water absorption cavity (9) and the water outlet cavity (8) are closed; and when the water drainage bolt (3) screwed on the water drainage port (7) is loosened or screwed out of the water drainage port (7), the water absorption cavity (9) and the water outlet cavity (8) are communicated, and water in the high-pressure water cavity flows into the low-pressure water cavity.
Description
Affiliated technical field
The present invention relates to a kind of water pump jettison gear, belong to pump and make the field with water distribution structure.
Background technique
Existing two chamber water pumps, its water sucting cavity and water chamber seal, and are not communicated with between low pressure liquid and the highly pressurised liquid, and this just makes the water in the high-pressure water chamber be difficult to flow in the low pressure water cavity, when we need two chambeies to be communicated with, can run into very big difficulty.
Summary of the invention
Technical problem to be solved by this invention is the deficiency of avoiding in the background technique, designs a kind of pump jettison gear, can be communicated with water sucting cavity and water chamber, and can effectively discharge water.
For realizing above-mentioned purpose of design, one water distribution structure is set in pump, this water distribution structure is that pump is regulated and control water distribution structure with the dewatering outlet plug screw, promptly between water sucting cavity and water chamber, have a dewatering outlet, and on the pump housing, have a hole of and dewatering outlet axis coaxle, this hole and drain screw body are threaded, and seal ring and seal ring baffle ring are housed.The logical and obstructed of water sucting cavity and water chamber controlled by the bolt that discharges water, and the degree that the bolt that discharges water is outwarded winding is by stop ring control.When the bolt that discharges water in being screwed in the dewatering outlet screwed, bolt head stopped up the dewatering outlet, water sucting cavity and water chamber sealing; The bolt that discharges water on being screwed in water outlet unscrews or when screwing out the dewatering outlet, water sucting cavity and water chamber are communicated with, and the water in the high-pressure water chamber flows in the low pressure water cavity.
The invention has the beneficial effects as follows the problem that discharges water that has solved water sucting cavity and water chamber, when needs discharge water, can directly discharge, easy to use.The present invention is simple in structure, safe and reliable, manufacturing is simple, and cost is low.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is that structure of the present invention is always schemed.
As shown in the figure, 1. pumps among the figure, 2. drain screw body, the bolt that 3. discharges water, 4. seal ring, 5. seal ring baffle ring, 6. stop ring, 7. dewatering outlet, 8. water chamber, 9. water sucting cavity.
Embodiment
By shown in Figure 1, between water sucting cavity 9 and water chamber 8, have a dewatering outlet 7, and on the pump housing 1, have a hole of and dewatering outlet 7 axis coaxles, this hole and drain screw body 2 are threaded, and seal ring 4 and seal ring baffle ring 5 be housed, the logical and obstructed of water sucting cavity 9 and water chamber 8 controlled by the bolt 3 that discharges water, and the degree that the bolt 3 that discharges water is outwarded winding is by stop ring 6 controls.When the bolt 3 that discharges water in being screwed in dewatering outlet 7 screwed, bolt head stopped up dewatering outlet 7, water sucting cavity 9 and water chamber 8 sealings; The bolt 3 that discharges water on being screwed in water outlet 7 unscrews or when screwing out dewatering outlet 7, water sucting cavity 9 and water chamber 8 are communicated with, and the water in the high-pressure water chamber flows in the low pressure water cavity.
Claims (3)
1. pump jettison gear, it is characterized in that: have a dewatering outlet (7) between water sucting cavity (9) and the water chamber (8), and on the pump housing (1), have a hole of and dewatering outlet (7) axis coaxle, this hole and drain screw body (2) are threaded, and seal ring (4) and seal ring baffle ring (5) be housed, logical and the obstructed employing of water sucting cavity (9) and water chamber (8) bolt (3) control that discharges water.
2. according to claim a kind of described pump water distribution structure, it is characterized in that: the bolt that discharges water (3) bolt head that discharges water when screwing just in time withstands the boiling water mouth.
3. according to claim a kind of described pump water distribution structure, it is characterized in that: the degree that the bolt that discharges water (3) is outwarded winding is by stop ring (6) control.
