Description
Technical field
The utility model belongs to high-lift water supply and drainage field, particularly relates to a kind of pump-stopping water hammer effect cancellation element.
Background technology
Along with the application of the development of economic technology and new equipment, new technology, increasing large discharge, high-lift plumbing equipment are applied to the engineering fields such as building, municipal administration and water conservancy, and the water hammer simultaneously existed in such high-lift, long distance water supply and sewage work also more and more comes into one's own.
High-lift, long distance water supply and sewage work are in order to alleviate water hammer impact at present, and adopt water-hammer arrester, but engineering practice shows, simple installs water-hammer arrester on water pump water outlet pipeline, and effect is poor more.When water pump all standing moment, pump-stopping water hammer phenomenon is serious, have impact on the application life of water supply and sewerage pipeline greatly.
In addition, at present high-lift, long distance water supply and sewage work also delayed by water pump open, generation that the slow mode of stopping prevents water hammer.Under normal circumstances, this kind of mode effectively can prevent water hammer, but as accidents such as burst have a power failure, after water pump all standing, pump-stopping water hammer is inevitable, there is potential safety hazard.
In sum, high-lift, the long distance water supply and sewage work pump-stopping water hammer effect cancellation element that needs a set of installation simple and easy, reliable and stable at present.
Summary of the invention
The purpose of this utility model is the pump-stopping water hammer phenomenon for existing in high-lift, long distance water supply and sewage work, provides a kind of pump-stopping water hammer effect cancellation element, reduces and even eliminate water hammer, protect the safe and reliable of pipe-line system.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides and a kind of pump-stopping water hammer effect cancellation element, it is characterized in that: comprise water pump water outlet main, described water pump water outlet main one end is connected with water pump, the other end and supply and drain water system export, described water pump water outlet main is provided with out water conduit tube flap valve, described water pump water outlet main is connected with bypass pipe, moisturizing bypass pipe, described bypass pipe is positioned at water conduit tube check valve downstream, described moisturizing bypass pipe is positioned at the upstream of water conduit tube flap valve, described bypass pipe is provided with maintenance gate valve, bypass line check valve, the described bypass pipe other end is connected with high level cistern, and be connected to the bottom of high level cistern, described bypass pipe is connected with pressure release arm, described pressure release arm is provided with pressure release arm flap valve, relief valve, described moisturizing bypass pipe is provided with maintenance valve successively, moisturizing bypass line check valve, the described moisturizing bypass pipe other end is positioned at high level cistern and is provided with waterpower fluid level control valve.
The described pressure release arm other end connects floor drain or sump or other drainage measure places.
The beneficial effects of the utility model are: this pump-stopping water hammer effect cancellation element can be pipeline moisturizing at water pump all standing on the one hand instantaneously, and eliminate or reduce pipeline negative pressure, the process formed from water hammer goes the effect alleviating water hammer; On the other hand, after water hammer is formed, adopt the mode that superpressure sluices, by Stress control below limiting value, adequately protect pipeline.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-water pump water outlet main, 2-goes out water conduit tube flap valve, and 3-overhauls gate valve, 4-bypass pipe, 5-bypass line check valve, 6-high level cistern, 7-waterpower fluid level control valve, 8-moisturizing bypass line check valve, 9-pressure release arm flap valve, 10-relief valve, 11-overhauls valve, 12-moisturizing bypass pipe, and 13-supply and drain water system exports, 14-water pump, 15-pressure release arm.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
The present embodiment comprises water pump water outlet main 1, water pump water outlet main 1 one end is connected with water pump 14, the other end and supply and drain water system export 13, water pump water outlet main 1 is provided with out water conduit tube flap valve 2, water pump water outlet main 1 is connected with bypass pipe 4, moisturizing bypass pipe 12, bypass pipe 4 is positioned at water conduit tube flap valve 2 downstream, moisturizing bypass pipe 12 is positioned at the upstream of water conduit tube flap valve 2, bypass pipe 4 is provided with maintenance gate valve 3, bypass line check valve 5, bypass pipe 4 other end is connected with high level cistern 6, and be connected to the bottom of high level cistern 6, bypass pipe 4 is connected with pressure release arm 15, pressure release arm 15 is provided with pressure release arm flap valve 9, relief valve 10, pressure release arm 15 other end connects floor drain or sump or other drainage measure places, moisturizing bypass pipe 12 is provided with successively maintenance valve 11, moisturizing bypass line check valve 8, moisturizing bypass pipe 12 other end is positioned at high level cistern 6 and is provided with waterpower fluid level control valve 7.
Operating principle:
1, in termination of pumping moment, by high level cistern moisturizing, prevent main gas-water separation, eliminate or reduce water hammering power.
2, pressure release arm is set, when making water hammering power exceed pressure release value, reduces water hammering by pressure release.
Implementation process: after water pump normally starts, high level cistern, by filling pipe moisturizing, stops moisturizing by waterpower fluid level control valve after filling; After water pump all standing, because fluid inertia produces negative pressure in check valve downstream, water tank is pumping line moisturizing by check valve downstream bypass pipe, prevents aqueous vapor to be separated; After fluid inertia terminates, there is negative pressure backflow, produce the possibility of water hammer, water hammer acts predominantly on pumping line check valve downstream place.Water hammer occurs in herein, and active force conducts to relief valve by bypass pipe, and when pressure is higher than pressure release value, relief valve pressure release, reduces water hammering power, reduces water hammer to the impact of pipeline.
Utilize technical scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technical scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
