Abstract

The utility model discloses a vertical type multistage pump with an automatic air valve. The vertical type multistage pump with the automatic air valve comprises a water cavity with a liquid in-out opening and an exhaust floating ball. The exhaust floating ball is arranged in the water cavity to separate the water cavity into an upper cavity and a lower cavity, and the liquid in-out opening is formed in the lower cavity. The exhaust floating ball is arranged so that manual exhaust can be of no need when the vertical type multistage pump is used for the first time. In the working process, even though gas enters the inside of the water cavity, the gas can be exhausted timely, idle rotation of a water pump and damaging of mechanical sealing are avoided, the structure is simple, and practicability is achieved.

Description

A kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent
Technical field
The utility model relates to the pump technology field, relates in particular to a kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent.
Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging.It sends the mechanical energy of prime mover or other external energies to liquid, and liquid energy is increased, and is mainly used to carry comprise the liquid such as water, oil, acid ﹠ alkali liquid, emulsified liquid, suspended emulsion, liquid metal.
MODEL VERTICAL MULTISTAGE PUMP; because its lift is higher; floor space is smaller; therefore be widely used, because the water pump intake-outlet is positioned at the bottom of pump, the above is a vertical water cavity; because the relation of density; deaeration not in time often has air accumulation in the above in water cavity, if can cause the water pump air sinuses not show water or the dried accessories such as damaging mechanical seal that turns.Must manual exhaust when therefore all water pumps all require to work for the first time at present; Be sealed with leakage for pump water inlet mouth pipeline valve, the moisturizing of water intake water tank is in above water intake, and the import water tank does not have the liquid level protection to control, and the washing machine industry often will be changed the system of water, also want often artificial exhaust, wrong operator or forget exhaust wastes a large amount of manpowers, in case can cause water pump not show water or dried turning, damage mechanical seal, cause the pump cisco unity malfunction, namely produce maintenance expenses, impact is produced again; Also there is shorter defect in working life.
Therefore, need especially a kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent, to solve problems of the prior art.
The model utility content
The purpose of this utility model is in order to solve in prior art MODEL VERTICAL MULTISTAGE PUMP because import and export are positioned at bottom, exist unnecessary gas can cause that water pump is dried to be turned in water cavity, damage mechanical seal, the defect that causes the water pump cisco unity malfunction, provide a kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent to solve the problems referred to above.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent, comprise the water cavity with liquid entrance, it is characterized in that, also comprises the exhaust ball float, and described exhaust ball float is arranged in water cavity water cavity is divided into epicoele and cavity of resorption; Described liquid entrance is arranged on cavity of resorption.
In the utility model, that end that described exhaust ball float contacts with epicoele arranges pull bar, and described pull bar connects the epicoele top.
In the utility model, described epicoele top arranges spring stack, and described pull bar connects the epicoele top by spring stack.
In the utility model, the pulling force that described spring stack produces the exhaust ball float by pull bar is less than the gravity of exhaust ball float self.
In the utility model, described water cavity is cylindrical.
In the utility model, be coated with rust proof paint on described exhaust ball float.。
A kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent of the present utility model, compared with prior art,, by the exhaust ball float is set in water cavity, use MODEL VERTICAL MULTISTAGE PUMP for the first time, do not need manual exhaust; , even gas enters water cavity inside and also can in time get rid of at work, avoid that water pump is dried to be turned, damage mechanical seal; Simple in structure, very practical, realize the purpose of this utility model.

Wherein: 1, water cavity; 11, liquid influent mouth; 12, epicoele; 13, cavity of resorption; 2, exhaust ball float; 3, pull bar; 4, spring stack.
Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment, the utility model is further described.
Embodiment
As shown in Fig. 1-4, Fig. 1 is structural representation of the present utility model; Fig. 2 is the structural representation of water cavity; Fig. 3 is the overall structure schematic diagram of the utility model MODEL VERTICAL MULTISTAGE PUMP; Fig. 4 is the plan view of Fig. 3.
A kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent, comprise the water cavity 1 with liquid entrance 11, a kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent, also comprise exhaust ball float 2, exhaust ball float 2 is arranged on that water cavity 1 is interior is divided into epicoele 12 and cavity of resorption 13 with water cavity 1, epicoele 12 and cavity of resorption 13 are respectively the cavity of two sealings, and exhaust ball float 2 slides up and down by floating function, thereby change the volume of epicoele 12, cavity of resorption 13; Liquid entrance 11 is arranged on cavity of resorption 13; Liquid enters cavity of resorption 12 from liquid entrance 11, and cavity of resorption 12 liquid are more, by floating function, makes exhaust ball float 2 increase gradually, and cavity of resorption 13 volumes are increased gradually, and the volume of epicoele 12 reduces gradually, reaches the purpose of exhaust.
That end that exhaust ball float 2 contacts with epicoele 12 arranges pull bar 3, and pull bar 3 connects epicoele 12 tops; Play firm support and spacing effect by 3 pairs of exhaust ball floats 2 of pull bar.
Epicoele 12 tops arrange spring stack 4, and pull bar 3 connects epicoele 12 tops by spring stack 4; , by the elastic reaction of spring stack 4, reach the effect of flexible operation.
Spring stack 4 passes through the gravity of the pulling force of 3 pairs of exhaust ball floats generations of pull bar less than exhaust ball float self; Make the exhaust ball float press to all the time the water surface in chamber.
Water cavity 1 is cylindrical, is the better mode of execution of the utility model, reaches and seals effect closely.
Be coated with rust proof paint on exhaust ball float 2; For the better mode of execution of the utility model, effectively avoid exhaust ball float oxidation, impaired, increase working life of the present utility model.
When in use, the vertical multi-stage pump work, liquid flows into cavity of resorption 13 from the liquid entrance 11 of water cavity 1 bottom, and the interior current of cavity of resorption 13 increase gradually, the upper end of epicoele 12 arranges the relief opening (not shown) rises exhaust ball float 2 by floating function gradually, thereby reaches the purpose of exhaust.
A kind of MODEL VERTICAL MULTISTAGE PUMP with automatic control pressure vent of the present utility model, compared with prior art,, by exhaust ball float 2 is set, use MODEL VERTICAL MULTISTAGE PUMP for the first time, do not need manual exhaust; , even gas enters water cavity inside and also can in time get rid of at work, avoid that water pump is dried to be turned, damage mechanical seal; Simple in structure, very practical, realize the purpose of this utility model.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiments, and in the General Principle of this explanation is applied to other embodiments and needn't pass through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art are according to announcement of the present utility model, and not breaking away from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
