Abstract
The utility model provides a water hammer protection device and belongs to water delivery pipeline protection equipment. The water hammer protection device comprises a water pump, a water reservoir and a main pipe. The water hammer protection device is characterized in that an outlet of the water pump is communicated with the main pipe, a check valve I is arranged on the main pipe, a small-diameter branch pipe is arranged between the water pump and the check valve I, a four-way joint is connected to the branch pipe, a check valve II opposite to the check valve I in an opening direction is additionally mounted on one line of the four-way joint, one line of the four-way joint is communicated with the main pipe, a check valve III opposite to the check valve I in an opening direction is additionally mounted on one line of the four-way joint, and communicated with the water reservoir, and a butterfly valve is additionally mounted on one line of the four-way joint and communicated with the water reservoir. The water hammer protection device is low in manufacture cost, simple in structure and not easy to damage.
Description
Technical field
The utility model relates to a kind of waterline safeguard, is specifically related to a kind of protecting water hammer device.
Background technology
Long distance, large flow velocity, high-lift water supply line, obvious water hammer, when termination of pumping (particularly pumping accident), occurs in the pumping plant outlet in the head pivot pumping plant.The water hammer abatement apparatus (water-hammer arrester, air pressure container) that adopt producer directly to produce at present more.This equipment is not only expensive, and fraction is not high, because water hammer may not occur once the several years, once occur, equipment is malfunctioning possibly.
Summary of the invention
The utility model provides a kind of cheap, simple structure, non-damageable protecting water hammer device.
The purpose of this utility model realizes by following technological means:
A kind of protecting water hammer device, comprise water pump, reservoir, main, it is characterized in that, described exit of pump and main connect, non retern valve I is set on described main, between described water pump and described non retern valve I, the pipe with small pipe diameter arm is set, described arm connects a four-way, described four-way one tunnel installs one additional opens to contrary non retern valve II with non retern valve I, described four-way one tunnel and main connect, described four-way one tunnel installs one additional opens to contrary non retern valve III and with reservoir and connects with non retern valve I, and described four-way one tunnel installs butterfly valve additional and connects with reservoir.
The beneficial effects of the utility model are: cheap, simple structure, not fragile.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, water pump, 2, reservoir, 3, main, 4, arm, 5, four-way, 6, non retern valve I, 7, non retern valve II, 8, non retern valve III, 9, butterfly valve.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is described in further detail:
A kind of protecting water hammer device as shown in Figure 1, comprise water pump 1, reservoir 2, main 3, wherein, described water pump 1 outlet connects with main 3, on described main 3, non retern valve I6 is set, between described water pump 1 and described non retern valve I6, pipe with small pipe diameter arm 4 is set, described arm 4 connects a four-way 5, described four-way 5 one tunnels install one additional opens to contrary non retern valve II7 with non retern valve I6, described four-way 5 one tunnels and main 3 connect, described four-way 5 one tunnels install one additional opens to contrary non retern valve III8 and with reservoir 2 and connects with non retern valve I6, described four-way 5 one tunnels install butterfly valve 9 additional and connect with reservoir 2.
When water pump normally moves, non retern valve I6 opens, and non retern valve II7, non retern valve III8 close, and butterfly valve 9 opens after a reservoir 2 holds completely and cuts out; When termination of pumping occurs, water continues to move ahead under effect of inertia, and water pump 1 outlet will produce negative pressure, pressure drop, and now non retern valve I6 closes, and non retern valve III8 opens and carries out moisturizing (if but the pumping plant lift is low, the little also tonifying Qi of flow velocity, now do not establish pond); When manifold pressure raises, non retern valve II7 opens, and water sluices to main 3 (flow and flow velocity are little, act on water pump vane pressure very little, can not make unit produce large reversion) through bypass pipe.Like this during termination of pumping, by play the effect of protection water pump and pipeline to pipeline moisturizing (gas) and draining.
The above; it is only a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
