Abstract
The invention relates to the technical field of water supply equipment, in particular to a two-state protection device. The two-state protection device comprises a steady flow compensator and a water supply pump, wherein the water supply pump is connected with the steady flow compensator through a water delivery hose and is divided into a water pump I and a water pump II; the water pump I is connected with the water pump II in parallel; a manual valve is connected in series on the side, close to the steady flow compensator, of the water supply pump, and a check valve is connected in series on the other side; the water supply pump is connected in parallel with a two-state protector; a check valve is connected in series on one side of the two-state protector. According to the improved two-state protection device, water is not stopped under any condition, so normal water utilization of a user is effectively guaranteed, the water supply efficiency is also effectively improved, and great economic and social benefit is produced.
Description
Technical field
The present invention relates to supply equipment technical field, especially a kind of bifurcation protective device.
Background technology
In the high-rise constant pressure water supply equipment of tradition when pressure of supply water higher than a certain state or equipment intake pressure lower than a certain state time, system can only be shut down, and when band pressure falls after rise or gos up to particular value, system could normal work.Also there is following problem in the high-rise constant pressure water supply equipment of tradition: 1., when equipment influent pressure is lower than a certain setting value, system by autostop, and then causes all users to cut off the water, and when only having intake pressure rise by the time to certain value, system just normally starts; 2., when equipment pressure of supply water is higher than a certain setting value, system is by autostop, and also can cause the just conventional water of user, when only having pressure of supply water rise by the time to certain value, system just normally starts; 3. local frequently in municipal water supply pressure oscillation, the frequent starting of equipment can be caused, the direct application life affecting equipment.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides a kind of bifurcation protective device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bifurcation protective device; comprise steady flow compensator and supply-water pump; supply-water pump is connected with steady flow compensator by delivery hose; supply-water pump is divided into water pump one and water pump two; water pump one and water pump two parallel connection, supply-water pump is in series with manually-operated gate near the side of steady flow compensator, and opposite side is in series with flap valve; supply-water pump two ends are parallel with bifurcation degree protector, and bifurcation degree protector side is in series with flap valve.
The invention has the beneficial effects as follows, no matter all can not cut off the water in what situations, not only effectively ensure that the just conventional water of user, also effectively improve water application efficiency, create very large economic and social benefit.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. steady flow compensator, 2. manually-operated gate, 3. supply-water pump in figure, 3-1. water pump one, 3-2. water pump two, 4. flap valve, 5. bifurcation degree protector.
Detailed description of the invention
If Fig. 1 is structural representation of the present invention; a kind of bifurcation protective device; comprise steady flow compensator 1 and supply-water pump 3; supply-water pump 3 is connected with steady flow compensator 1 by delivery hose, and supply-water pump 3 is divided into water pump one 3-1 and water pump two 3-2, water pump one 3-1 and water pump two 3-2 in parallel; supply-water pump 3 is in series with manually-operated gate 2 near the side of steady flow compensator 1; opposite side is in series with flap valve 4, and supply-water pump 3 two ends are parallel with bifurcation degree protector 5, and bifurcation degree protector 5 side is in series with flap valve 4.
When intake pressure is lower than a certain setting value, bifurcation degree protector 5 is started working, and by a pressure of supply water transfer part in steady flow compensator 1, suitably improves hydraulic pressure in expansion loop 1, can ensure the just conventional water of a part of user; When discharge pressure is higher than a certain setting value, bifurcation degree protector 5 starts, and by pressure Self-tipping in steady flow compensator 1, suitably reduces pressure of supply water, ensures the normal operation of equipment.
No matter the bifurcation protective device after improvement all can not be cut off the water in what situations, not only effectively ensure that the just conventional water of user, also effectively improve water application efficiency, create very large economic and social benefit.
