Abstract
The utility model discloses a water pump evacuator which comprises a three-way valve arranged on a water inlet pipe of a water pump, an evacuator body communicated with the three-way valve, and a one-way valve arranged at the connecting end of the evacuator body and the three-way valve. The evacuator body is a vacuum pump or a manual plunger pump. A piston suction pump is adopted as the best evacuator body so as to facilitate matching between the evacuator body and the water pump. The three-way valve is preset on the water inlet pipe of the water pump to be matched with the evacuator body, and the one-way valve is arranged at the front end of the matched evacuator body to achieve the evacuation requirements when the water pump is started at any time. The evacuator body can be the vacuum pump, and preferably, is the piston suction pump. The water pump evacuator is simple in structure, convenient to use, and capable of being matched with the water pump equipment and meeting requirements of the water pump for starting, especially for the requirements of a fire pump for emergency starting.
Description
Technical field
The utility model belongs to Machine Design and makes the field, especially belongs to the water pump accessory and manufactures and designs the field, particularly a kind of evacuator of fire service pump.
Background technique
In the water pump linkage structure, the water intake of conventional station pump is equipped with bottom valve, and the purpose of bottom valve is can not normally start because of water pump behind the high low head formation of the intake pipe cavity in order to prevent.In the fire service pump linkage structure, because of fire service pump usually uses at unconventional state, intake pipe connects the back usually also has air to exist at feed-water end, and air forms cavity influences the normal water outlet of starting mode of pump, it need be discharged.The method of exhausting air can adopt method such as pour water usually, also can adopt equipment emptyings such as evacuator such as vacuum pump, under urgent, dangerous situation, adopts said method not satisfy the demand, and can bungle the chance of winning a battle, and causes bigger loss.As by water pump self-suction, the high and fluid speed that decided by pump performance and unstable of water pump cost can not satisfy quick, strong fire extinguishing needs.
Summary of the invention
The utility model discloses a kind of water pump evacuator according to the deficiencies in the prior art.Problem to be solved in the utility model provides a kind of portable easy device of the air in the intake pipe being carried out emptying before making things convenient for water pump to draw water to start.
The utility model is achieved through the following technical solutions:
The water pump evacuator comprises the three-way valve that is arranged on the pump water inlet, it is characterized in that: comprise also and the evacuator of three-way valve UNICOM that evacuator and three-way valve connecting end have one-way valve; Described evacuator is vacuum pump or hand piston pump.
For with prescription just, best evacuator adopts the piston type pump bowl.
Water pump has a large amount of air to start than difficult when starting such as in the intake pipe, usually air need be discharged, comprise methods such as the emptying of pouring water in the existing method, but in case of emergency, during as the fire service pump emergency start, as the operation of pouring water will be lost time, bungle the chance of winning a battle, cause bigger loss, limited by complex environment, needing can be in time, evacuator easily, the utility model is default three-way valve on pump water inlet, when urgency needs, connecting end is preset with the evacuator and the three-way valve UNICOM of one-way valve, start rapidly and can start water pump after evacuator is discharged air.Optimal scheme is with joining a plunger pump or piston type pump bowl, at the default one-way valve of its front end, under any condition, itself and three-way valve UNICOM can be carried out the emptying operation.After the emptying,, close three-way valve, take off evacuator starting mode of pump.
The utility model helpfulness is: the utility model adopts default three-way valve on pump water inlet, with its coupling, with the evacuator front end of joining one-way valve is being set, realized the emptying needs that water pump starts at any time, evacuator can be a vacuum pump, and the best is the piston type pump bowl.The utility model is simple for structure, and is easy to use, can with pump equipment with joining, satisfy the particularly needs of the fire service pump of emergency start of starting mode of pump.
Description of drawings
Fig. 1 is a kind of linkage structure schematic representation of the utility model.
Among the figure, the 1st, piston type pump bowl pull bar, the 2nd, piston type pump bowl cylindrical shell, the 3rd, one-way valve, the 4th, three-way valve, the 5th, water pump, F are the mobile directions of water.
Embodiment
Below by embodiment the utility model is further described; present embodiment only is used for the utility model is further detailed; but can not be interpreted as the restriction to the utility model protection domain, those skilled in the art can make the scope that some nonessential improvement and adjustment belong to the utility model protection according to above-mentioned content of the present utility model.
The water pump evacuator comprises the three-way valve 4 that is arranged on water pump 5 intake pipes, comprises also and the evacuator of three-way valve 4 UNICOMs that evacuator and three-way valve 4 connecting ends have one-way valve 3, and evacuator is vacuum pump or hand piston pump or piston type pump bowl.
In conjunction with Fig. 1, as shown in the figure, the evacuator that this example adopts is the piston type pump bowl.The utility model water pump evacuator presets three-way valve 4 on water pump 5 intake pipes, and unused state three-way valve 4 external connection end are closed; Piston type pump bowl front end is provided with one-way valve 3, one-way valve 3 allows fluid to flow to the unidirectional extraction of piston type pump bowl, when needed, at first connect intake pipe and water pump 5, piston type pump bowl front end one-way valve 3 is connected with three-way valve 4, open three-way valve 4, bar twitching 1 repeatedly, and air is discharged; Start water pump 5 and can realize the operation of drawing water smoothly.
Claims (3)
