Abstract
The invention relates to a non-seal self-priming pump with an anti-siphon floating ball device. The non-seal self-priming pump comprises a non-seal self-priming pump body, a water inlet pipeline and an outlet pipeline. The non-seal self-priming pump is characterized in that limiting baffles are arranged at the position, close to the port of the water inlet pipeline, of a water storage chamber in the non-seal self-priming pump body; a circular floating ball is placed in the space formed by the limiting baffles and the port of the water inlet pipeline; the maximum cross section of the circular floating ball is larger than the cross section of the port of the water inlet pipeline, and the port of the water inlet pipeline is a circular hole. The non-seal self-priming pump is further characterized in that the circular floating ball is a hollow hard plastic ball and is made of PE rigid plastic; the space formed by the limiting baffles and the port of the water inlet pipeline is larger than the maximum size of the circular floating ball; the limiting baffles are net-shaped cages; the limiting baffles include an upper limiting baffle, a lower limiting baffle, a left limiting baffle, a right limiting baffle and a rear limiting baffle respectively, the sizes of gaps between the limiting baffles are smaller than the size of the circular floating ball, and the sizes between the limiting baffles and the walls of the water storage chamber of the non-seal self-priming pump body are smaller than the size of the circular floating ball. The non-seal self-priming pump has the advantages of being simple in structure, long in service life and capable of reducing production cost.
Description
Technical field
The present invention relates to a kind of non-sealing self-sucking pump with anti-siphon floating ball device.
Background technique
Without sealing self-controlling self-priming pump 10 for the function that meets " the permanent self-priming of once pouring water " conventionally needs have anti-siphon function.General anti-siphon function is in the inlet ductwork of pump, to connect an arm 11; an electric air control valve 12 is installed on arm; air valve is in closed condition in Start-up and operating performance process; when shutting down, valve also can synchronously be opened; now air enters the inlet ductwork of pump by valve; reach the object of the vacuum state that destroys inlet ductwork, the liquid in pump also just can not sucked back inlet ductwork by siphonage and caused in pump no liquid so.But such device needs electrically-controlled valve to synchronize with the start and stop of motor, when motor is high-voltage motor, electrically-controlled valve generally all can not be done high pressure, if another connection control circuit bothers again very much, and the spool of electrically-controlled valve is all rubber-like, be easy to aged deterioration, and use on-the-spotly when having explosive-proof grade to require when running into, electrically-controlled valve is also difficult to adapt to those requirements.
Summary of the invention
The object of the invention is to solve nothing sealing self-controlling self-priming pump in prior art the existing the problems referred to above of electric air control valve need to be set, a kind of non-sealing self-sucking pump with anti-siphon floating ball device is provided.The present invention designs a kind of non-sealing self-sucking pump with anti-siphon floating ball device, comprise non-sealing self-sucking pump, inlet pipeline, export pipeline, it is characterized in that: the place, the nearly intake pipe of water chamber crossing in the pump housing of non-sealing self-sucking pump arranges postive stop baffle, at postive stop baffle and Chu space, intake pipe crossing, be placed with a circular ball float, the maximum cross section of circular ball float is greater than the cross section at place, intake pipe crossing, and intake pipe crossing is a circular hole.It is characterized in that: circular ball float is a hollow rigid plastic balls, by PE duroplasts, is made.It is characterized in that: postive stop baffle and Chu space, intake pipe crossing are greater than the overall dimensions of circular ball float.It is characterized in that: postive stop baffle is a netted cage.It is characterized in that: postive stop baffle is by upper and lower, left and right, rear five baffle plates, and the gap between the water storage locular wall of baffle plate and baffle plate and baffle plate and non-sealing self-sucking pump is less than circular ball float size.It is characterized in that: baffle plate is strip.Advantage of the present invention is simple in structure, and the life-span is long, reduces production costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.Accompanying drawing 2 is section of structure of the present invention.
Embodiment
Figure comprises non-sealing self-sucking pump 1, inlet pipeline 2, export pipeline 3, it is characterized in that: 5 places, water chamber 4 nearly intake pipe crossing in the pump housing of non-sealing self-sucking pump arrange postive stop baffle 6, at postive stop baffle and Chu space, intake pipe crossing, be placed with a circular ball float 7, the maximum cross section of circular ball float is greater than the cross section at place, intake pipe crossing, and intake pipe crossing is a circular hole.It is characterized in that: circular ball float is a hollow rigid plastic balls, by PE duroplasts, is made.It is characterized in that: postive stop baffle and Chu space, intake pipe crossing are greater than the overall dimensions of circular ball float.It is characterized in that: postive stop baffle is a netted cage.It is characterized in that: postive stop baffle is by upper and lower, left and right, rear five baffle plates, and the gap between the water storage locular wall of baffle plate and baffle plate and baffle plate and non-sealing self-sucking pump is less than circular ball float size.It is characterized in that: baffle plate is strip.
According to usage requirement and the structural feature without sealing self-controlling self-priming pump, the inlet pipeline of its pump is long, the inlet pipeline of pump must be to be also connected to above the water chamber of pump simultaneously, in order to form the state of gas-liquid mixed, water chamber all will be done to such an extent that have enough spaces conventionally, namely spatial structure is larger, the place that so now can be connected with water chamber after the inlet ductwork without sealing self-controlling self-priming pump, by the floating ball device of a limited location, when reaching operation, can intake, when shutting down along with the backflow of current, ball float simultaneously return is blocked import, the effect that allows water in pump not reflux.Ball float itself is made of PE duroplasts, make hollow, can be to bubble through the water column, and have enough hardness to guarantee can be by current compressive strain, life-span of being certainly longer than the metal body of water pump in life-span simultaneously.Simple in structure, effective, also avoided needing the part of electric electric-controlled.
