Abstract
The utility model relates to a multistep throttling device of a circulating pipe. The multistep throttling device of the circulating pipe is characterized by comprising a box body (1). A water inlet (1.1) is arranged on one side of the box body (1), and a water outlet (1.2) is arranged on the other side of the box body (1). A plurality of separation boards (2) are vertically arranged inside the box body (1) from front to back, wherein each separation board (2) is provided with through holes (3) and the numbers of the through holes (3) from the separation board (2) close to the water inlet (1.1) to the separation board (2) close to the water outlet (1.2) are sequentially increased. The plurality of separation boards are vertically arranged inside the multistep throttling device of the circulating pipe from front to back, wherein the numbers of the through holes from the separation board close to the water inlet to the separation board close to the water outlet are sequentially increased, and thus pressure of high-pressure water flow can be decreased gradually through the through holes, the fact that an electrically operated valve is difficult to damage in impacted mode is guaranteed, and electric power is saved.
Description
Technical field
The utility model relates to a kind of multi-stage flow-throttling device of circulating pipe.
Background technique
Because circulating pipe is through being commonly used to logical high pressure water, and high pressure water when flowing for a long time easily mortor operated valve to being washed out, cause leaking in the circulatory system serious, frequent supercurrent when causing feed water pump normally to move has caused the ratio of station service higher, causes power wastage.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of so that mortor operated valve is difficult for washing out, and saves the multi-stage flow-throttling device of the circulating pipe of electricity consumption.
The purpose of this utility model is achieved in that
The multi-stage flow-throttling device of the utility model circulating pipe, comprise casing, the both sides of casing have water intake and water outlet, be provided with in the casing on the every dividing plate of dividing plate that vertically arranges before and after the polylith and all have through hole, wherein the dividing plate near the water inlet increases successively to the number of openings on the close dividing plate of water outlet.
The multi-stage flow-throttling device of the utility model circulating pipe has the following advantages:
The multi-stage flow-throttling device of the utility model circulating pipe arranges the dividing plate that vertically arranges before and after the polylith in inside, wherein the dividing plate of close water inlet increases successively to the upper number of openings of the dividing plate of close water outlet, thereby so that high-pressure water flow can slowly reduce pressure by via through holes, thereby guaranteed that mortor operated valve is difficult for washing out, saved electric power.
Description of drawings
Fig. 1 is the structural representation of the multi-stage flow-throttling device of the utility model circulating pipe.
Fig. 2 is the schematic diagram of Fig. 1 central diaphragm after in one line.
Among the figure: casing 1, water intake 1.1, water outlet 1.2, dividing plate 2, through hole 3.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of multi-stage flow-throttling device of circulating pipe, this multi-stage flow-throttling device comprises casing 1, this casing 1 is rectangular structure, the both sides of casing 1 have water intake 1.1 and water outlet 1.2, be provided with the dividing plate 2 that vertically arranges before and after the polylith in the casing 1, all have through hole 3 on the every dividing plate 2, wherein the dividing plate 2 near water intake 1.1 places increases successively to through hole 3 quantity on the close dividing plate 2 of water outlet 1.2, thereby so that high-pressure water flow can slowly reduce pressure by via through holes 4, thereby guaranteed that mortor operated valve is difficult for washing out, saved electric power.
Claims (1)
