Abstract
The utility model relates to a kind of water pump, particularly a kind of steam feed pump.Comprise the piston in the sealing pump housing, the pump housing, connect pneumatic motor, upper water intake, upper water-out mouth, lower water intake, the lower outlet of piston, upper water intake, upper water-out mouth, lower water intake, lower outlet install one-way valve separately, and upper water-out mouth is connected main water outlet pipe with lower outlet.The simple energy-conserving and environment-protective of the utility model structure, this one-way valve can use at water outlet and water intake simultaneously, and not fragile.
Description
Technical field
The utility model relates to a kind of water pump, particularly a kind of pneumatic feed water pump.
Background technique
Water pump is a kind of conventional water supplying tool, and conventional half has motor to drive, but some occasion belongs to inflammable and explosive environment can not use conventional water pump.
Summary of the invention
Technical problem to be solved in the utility model is: how to provide a kind of feed water pump, and this water pump can not safety and environmental protection, and can use in inflammable and explosive environment.
The technological scheme that the utility model adopts is: a kind of pneumatic feed water pump, comprise the piston in the sealing pump housing, the pump housing, connect pneumatic motor, upper water intake, upper water-out mouth, lower water intake, the lower outlet of piston, upper water intake, upper water-out mouth, lower water intake, lower outlet install one-way valve separately, and upper water-out mouth is connected main water outlet pipe with lower outlet.
As a kind of optimal way: one-way valve comprises the extra heavy pipe of one end, the permeable net be arranged on extra heavy pipe, the tubule of the other end, ball, extra heavy pipe and tubule are threaded connection, the diameter that the diameter of ball is greater than tubule is less than the diameter of extra heavy pipe, ball is between extra heavy pipe and tubule, upper water intake is connected the extra heavy pipe end of one-way valve with lower water intake, and upper water-out mouth is connected the tubule end of one-way valve with lower outlet.
The beneficial effects of the utility model are: the simple energy-conserving and environment-protective of the utility model structure, and this one-way valve can use at water outlet and water intake simultaneously, and not fragile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, the sealing pump housing, 2, piston, 3, upper water intake, 4, lower water intake, 5, upper water-out mouth, 6, lower outlet, 7, ball, 8, permeable net, 9, pneumatic motor.
Embodiment
As shown in Figure 1, the utility model uses piston type pneumatic motor to provide power, does not need electric power and oil gas to provide power, can move to all occasions, and environmental protection is practical.In use upper and lower water intake of the present utility model is connected water source, during piston runs downwards, water is drawn from upper water intake, discharge water from lower outlet, during piston upwards runs, draw water from the lower mouth of a river, discharge water from upper water-out mouth, the continuous effluent of main water outlet pipe can be ensured, the utility model is in all water outlets of upper and lower process simultaneously, maintains the stable of piston pressure, improves the efficiency of feed water pump.The one-way valve structures that the utility model uses is simple, one-way valve comprises the extra heavy pipe of one end, permeable net (chain link fence), the tubule of the other end, the ball be arranged on extra heavy pipe, extra heavy pipe and tubule are threaded connection, the diameter that the diameter of ball is greater than tubule is less than the diameter of extra heavy pipe, ball is between extra heavy pipe and tubule, upper water intake is connected the extra heavy pipe end of one-way valve with lower water intake, and upper water-out mouth is connected the tubule end of one-way valve with lower outlet.
Claims (2)
