Abstract
The utility model discloses a vacuum suppressor of a non-negative-pressure pressure-superposed water supply device, and belongs to the field of water supply facilities. The vacuum suppressor of the non-negative-pressure pressure-superposed water supply device comprises a housing arranged on the upper portion of a flow stabilizing tank, wherein the housing is composed of an upper portion housing and a lower portion housing, the upper portion housing is arranged on the top of the lower portion housing, the upper portion housing and the lower portion housing are mutually sealed, the lower end of the lower portion housing is communicated with the flow stabilizing tank, a flow guiding pipe and a floating ball device are arranged in the lower portion housing, the floating ball device comprises a floating ball body, a floating ball and a sealing base which is used in cooperation with the floating ball, the floating ball is arranged in the floating ball body, the outlet end of the floating ball body is communicated with the upper portion housing, the inlet end of the floating ball body is communicated with the flow stabilizing tank, one end of the flow guiding pipe is communicated with the upper portion housing, and the other end of the flow guiding pipe penetrates out of the lower portion housing and is communicated with the atmosphere. According to the vacuum suppressor of the non-negative-pressure pressure-superposed water supply device, an exhaust valve is replaced by the floating ball device, water enters the flow stabilizing tank, gas is discharged out of the flow stabilizing tank, when the flow stabilizing tank is filled with the water, closing is carried out, and the time for negative pressure elimination is greatly shortened.
Description
Technical field
The utility model belongs to water facilities field, is specially a kind of without negative pressure laminating water supply equipment vacuum suppresser.
Background technology
Without negative pressure laminating water supply equipment vacuum suppresser, be a kind of vacuum automatic eliminator, be mainly used in municipal water supply equipment, and in water supply process, need by vacuum suppresser, gas to be discharged with the steady-flow tank that vacuum suppresser is used in conjunction with.
In existing product, adopt automatic air valve, capacity is at 0.5L/S, and capacity is little, and negative pressure is eliminated time delay.
Utility model content
It is larger that the purpose of this utility model is to provide a kind of capacity, and negative pressure is eliminated the time comparatively rapidly without negative pressure laminating water supply equipment vacuum suppresser.
The technical scheme that realizes above-mentioned purpose is: without negative pressure laminating water supply equipment vacuum suppresser, it is characterized in that: comprise the case that is arranged on steady-flow tank top, described case is comprised of upper cover and the lower closure by fastening bolt and sealing ring fit sealing, upper cover is arranged on the top of lower closure, and between mutually sealing, the lower end of lower closure is communicated with steady-flow tank; In described lower closure, be provided with mozzle and control the floating ball device that between upper cover and lower closure, connected sum seals, described floating ball device comprises floating ball body, ball float and the seal receptacle coordinating with ball float, ball float is placed in floating ball body, the port of export of floating ball body is connected with upper cover, described floating ball body entrance point is connected with steady-flow tank, one end of described mozzle is communicated with upper cover, and the other end of mozzle passes lower closure and is communicated with atmosphere.
The course of work of the present utility model:
The water of city planting ductwork enters steady-flow tank, and the water level in steady-flow tank rises, the upper cover that the floating ball body of gas process floating ball device enters vacuum suppresser, and enter atmosphere by the mozzle being communicated with upper cover.In steady-flow tank, be full of after water, ball float is closed automatically by buoyancy of water.When the water level decline of secondary water-supply (pump is taken out steady-flow tank water) steady-flow tank, ball float is opened, and air enters, and city planting ductwork continues to supply water.
The utility model changes floating ball device into by outlet valve, and steady-flow tank water inlet exhaust, fills and close, and capacity is brought up to 1.5L/S by 0.5L/S, and the negative pressure time of eliminating shortens greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises the case 2 that is arranged on steady-flow tank 1 top, case 2 is comprised of upper cover 5 and the lower closure 6 by fastening bolt 3 and sealing ring 4 fit sealings, upper cover 5 is arranged on the top of lower closure 6, and between mutually sealing, the lower end of lower closure 2 is communicated with steady-flow tank 1.
In lower closure 6, be provided with mozzle 7 and control the floating ball device 8 that between upper cover 5 and lower closure 6, connected sum seals, described floating ball device 8 comprises floating ball body 9, ball float 10 and the seal receptacle 11 coordinating with ball float 10, ball float 10 is placed in floating ball body 9, the port of export of floating ball body 9 is connected with upper cover 5, the port of export of floating ball body 9 is connected with steady-flow tank 1, one end of mozzle 7 is communicated with upper cover 5, and the other end of mozzle 7 passes lower closure 2 and is communicated with atmosphere.
Summary
Without negative pressure laminating water supply equipment vacuum suppresser, belong to water facilities field.Comprise the case that is arranged on steady-flow tank top, described case is comprised of upper cover and lower closure, and upper cover is arranged on the top of lower closure, and between mutually sealing, the lower end of lower closure is communicated with steady-flow tank; In described lower closure, be provided with mozzle and floating ball device, described floating ball device comprises floating ball body, ball float and the seal receptacle coordinating with ball float, ball float is placed in floating ball body, the port of export of floating ball body is connected with upper cover, described floating ball body entrance point is connected with steady-flow tank, one end of described mozzle is communicated with upper cover, and the other end of mozzle passes lower closure and is communicated with atmosphere.The utility model changes floating ball device into by outlet valve, and steady-flow tank water inlet exhaust, fills and close, and capacity is brought up to 1.5L/S by 0.5L/S, and the negative pressure time of eliminating shortens greatly.
