Abstract
A complete set of fire protection water supply equipment comprises a self-suction dual-inlet water pump, a constant pressure dual-outlet water pump, a check valve, a pipeline and the like, the fire protection water supply equipment is characterized in that: a self-suction device is arranged on the self-suction dual-inlet pump, the self-suction device is connected with a water inlet of the constant pressure dual-outlet water pump by the other water inlet of the self-suction dual-inlet water pump, the check valve is further arranged between the self-suction dual-inlet water pump and the self-suction device, one water outlet of the constant pressure dual-outlet water pump is connected with a constant pressure device, the other water outlet of the constant pressure dual-outlet water pump is connected with a water outlet main pipe by a valve, the water outlet of the self-suction dual-inlet water pump is connected with the water outlet main pipe by the check valve, therefore, the complete set of fire protection water supply equipment has the functions of self-suction and constant pressure, the production cost is simultaneously reduced, the labor intensity and the occupying area of installers are further reduced.
Description
One: technical field
The present invention relates to a kind of complete supply equipment that in fire-fighting system, uses, particularly self-priming constant voltage water-supply installation for fire fighting.
Two: background technology
All there are not diversion and constant-voltage equipment in the fire fighting water work in the prior art; if its pond, water source position absolute altitude distant apart from equipment or the pond, water source is lower than the water inlet of pump in the fire fighting equipment in use for equipment like this; at this moment equipment is with regard to cisco unity malfunction; diversion jar equipment ability operate as normal need be set at the water inlet of equipment; occupation area of equipment is just bigger like this; the quantity that while fire fighting equipment delivery port is opened owing to fire hydrant differs; cause the outlet pressure superelevation through regular meeting; it is safe in utilization to influence equipment; must install stable-pressure device additional at the outfall sewer place as addressing this problem, so just cause the consumption of lot of manpower and material resources.
Three: summary of the invention
The objective of the invention is to: design a kind of fire fighting water work that carries priming device and constant-voltage equipment, make its Installation and Debugging simple, reduce production costs, floor space is little and safe and reliable.
The present invention adopts following structure to realize above-mentioned purpose, the fire fighting water work comprises: self-priming double feed inlet water pump, the constant voltage double-exit water pump, non-return valve, pipe valve etc., on the self-priming double-entry pump, self-priming apparatus is installed, self-priming apparatus couples together by another water inlet of self-priming double feed inlet water pump and the water inlet of constant voltage double-exit water pump, non-return valve also is installed between them, the delivery port of constant voltage double-exit water pump is connected with constant-voltage equipment, another delivery port of constant voltage double-exit water pump is connected with outfall sewer by valve, and the delivery port of self-priming double feed inlet water pump is connected with outfall sewer by non-return valve.
Adopt as above structure, because the water inlet at the self-priming double-entry pump is equipped with self-priming apparatus, self-priming apparatus is connected with the constant voltage double-exit water pump by the self-priming double-entry pump simultaneously, at this moment the self-priming apparatus in the self-priming double feed inlet water pump just can supply water to constant voltage double-exit water pump and self-priming double-entry pump simultaneously, all pumps in the fire fighting wetting system have just all had self-suction function like this, the limitation of the installation site of fire fighting wetting system has not just had fully, so just fall installer's labour intensity and floor space greatly, reduced resource consumption; Constant-voltage equipment in the constant voltage double-exit water pump couples together by another delivery port of constant voltage double-exit water pump and outfall sewer simultaneously, the unnecessary water of the delivery port of self-priming double-entry pump just can pass through outfall sewer like this, flow to the constant-voltage equipment in the constant voltage double-exit water pump then, at this moment the outlet pressure of self-priming double feed inlet water pump also can carry out constant pressure by the constant-voltage equipment of constant voltage double-exit water pump.
Four: description of drawings
Figure one is structure chart of the present invention
Five: the specific embodiment
Water-supply installation for fire fighting, comprise: self-priming double feed inlet water pump 1, constant voltage double-exit water pump 2, non-return valve 4, pipeline 5 etc., Fig. 1 is the invention process user mode figure, the water inlet 6 of self-priming double feed inlet water pump 1 is connected with self-priming apparatus 7, self-priming apparatus 7 is provided with the mouth of pipe 8 of water source water inlet, self-priming apparatus 7 couples together by another water inlet 9 of the two water inlet pumps 1 of self-priming and the water inlet 10 of constant voltage double-exit water pump 2, between the water inlet 9 of the two water inlet pumps 1 of suction and the water inlet 10 of constant voltage double-exit water pump 2 non-return valve 4 is installed, the water source just can supply water to self-priming double feed inlet water pump 1 and constant voltage double-exit water pump 2 simultaneously by the self-priming apparatus in the self-priming double feed inlet water pump 17 like this, the delivery port 11 of self-priming double feed inlet water pump 1 is connected with outfall sewer 12 by non-return valve 4, outfall sewer 12 also is connected by the delivery port 14 of valve 13 and constant voltage double-exit water pump 2, the delivery port 14 of constant voltage double-exit water pump 2 is connected with constant-voltage equipment 16 by another delivery port 15, the effluent pipe mouth 17 of constant-voltage equipment 16 is connected with user's drainage system (figure is mark not), the outlet of self-priming like this double feed inlet water pump 1 also just and the constant-voltage equipment 16 in the two outlet pumps 2 of constant voltage be communicated with, constant-voltage equipment 16 just can constant self-priming double feed inlet water pump 1 of while and the outlet pressure of constant voltage double-exit water pump 2.
