Drench valve is the significant components of composition deluge system, preact system, water curtain system and water injection system, is to open instantaneously, allow swelling enter automatic valve that valve pocket enters the distribution system of water supply.Deluge alarm valve not only has warning function, has the unlatching effect of control system simultaneously.Usual and import butterfly valve, solenoid valve, sluicing are tested valve, warning water system, manual-operated emergent valve, tensimeter etc. and are formed deluge valves unit.The feature of drench valve is that in drench valve, flap is opened rapidly after discovery fire alarm, and pressure flow sprays through fire_fighting pipe network and covers or isolate whole protected location from shower nozzle, is applicable to the place that the rear intensity of a fire on fire is swift and violent, fire load is large, should not control and uses.The opening ways of deluge valves unit is divided into automatically, manual and remote manual three kinds of modes.When protected location breaking out of fire, environment temperature raises, fire detecting system action, and drench valve is opened, and water performs fire-extinguishing function concurrently from deluge system ejection rapidly, and can send alerting signal, to reach the object of warning, control fire, fire extinguishing.This device also can form foam deluge system with foaming system, for the liquid fire of explosion danger of putting out a fire to save life and property.
Due to the installation of deluge alarm valve, operation, maintenance, operation and use, the personnel by grasping this systems technology are needed to come.And at present, the main mode of learning of this systematic knowledge and technology is: one is grasped by theories of learning principle knowledge and system diagram, due to theoretical property, nature static, the non-intuitive of written knowledge, make learner be difficult to grasp system technical details and dynamic state of run, be difficult to reach good results of learning; Two is pass through field observation, and grasped by the engineering practice of regular period, but because on-the-spot real system is installed in whole space, and equipment connection is hidden, the connection of deluge alarm valve and annex thereof and the linkage work process of valve group cannot be observed, so be not easy to grasp its principle of work for students vividly.
Utility model content
The purpose of this utility model be propose a kind of simple for production, practical, can practical operation, facilitate the teaching demonstration device of the deluge alarm valve group of teaching demonstration.
The technical solution of the utility model is achieved in that a kind of teaching demonstration device of deluge alarm valve group, comprises deluge alarm valve, and this deluge alarm valve is provided with chamber A, chamber B and chamber C; Described chamber A is connected with water inlet pipe and tapping pipe, and this water inlet pipe is provided with gate valve and non-return valve, and this tapping pipe is provided with ball valve; Described chamber B is connected with rising pipe and drainpipe, and this rising pipe is provided with gate valve and non-return valve, and this drainpipe is provided with ball valve, filtrator, delayer, pressure switch and warning water system; Described chamber C is connected with transmission tube, this transmission tube is split up into first point of transmission tube and second point of transmission tube, this first point of transmission tube is provided with solenoid valve, downstream pressure table and ball valve, and this second point of transmission tube is communicated with described water inlet pipe and is provided with non-return valve, gate valve, upstream pressure table and ball valve.
Principle of work and the course of work of ocular demonstration deluge alarm valve group is come by the deluge alarm valve of current, solenoid valve, remote activation and the course of action of annex thereof.
Further, described first point of transmission tube is also provided with manual actuation of button, can conveniently by manually demonstrating whole process.
More preferably, described deluge alarm valve, water inlet pipe, tapping pipe, rising pipe, drainpipe, delayer, transmission tube, first point of transmission tube and second point of transmission tube are made by transparent material, can observe the course of work of deluge alarm valve group more easily.
The utility model clear in structure, express directly perceived, be easy to accept, intuitively reflecting change and the course of action of its principle of work by improving device in kind, exciting the learning interest cultivating learner, increase learner to the perceptual knowledge of knowledge.

In figure: 1-deluge alarm valve, 2-tapping pipe, 3-water inlet pipe, 4-filtrator, 5-delayer, 6-drainpipe, 7-warning water system, 8-pressure switch, 9-rising pipe, 10-transmission tube, 101-first point of transmission tube, 102-second point of transmission tube, 11-solenoid valve, 12-downstream pressure table, 13-manual actuation of button, 14-upstream pressure table.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The teaching demonstration device of deluge alarm valve group as shown in Figure 1, comprises deluge alarm valve 1, and this deluge alarm valve 1 is provided with chamber A, chamber B and chamber C; Described chamber A is connected with water inlet pipe 3 and tapping pipe 2, and this water inlet pipe 3 is provided with gate valve and non-return valve, and this tapping pipe 2 is provided with ball valve; Described chamber B is connected with rising pipe 9 and drainpipe 6, and this rising pipe 9 is provided with gate valve and non-return valve, and this drainpipe 6 is provided with ball valve, filtrator 4, delayer 5, pressure switch 8 and warning water system 7; Described chamber C is connected with transmission tube 10, this transmission tube 10 is split up into first point of transmission tube 101 and second point of transmission tube 102, this first point of transmission tube 101 is provided with solenoid valve 11, downstream pressure table 12, manual actuation of button 13 and ball valve, and this second point of transmission tube 102 is communicated with described water inlet pipe 3 and is provided with non-return valve, gate valve, upstream pressure table 14 and ball valve.
Described deluge alarm valve 1, water inlet pipe 3, tapping pipe 2, rising pipe 9, drainpipe 6, delayer 5, transmission tube 10, first point of transmission tube 101 and second point of transmission tube 102 are made by transparent material.
Principle of work and the course of work of the teaching demonstration device of this deluge alarm valve group are as follows: chamber A, chamber B, chamber C are all full of water at ordinary times, its lumen A identical with the water pressure in the C of chamber (because chamber C is communicated with water inlet pipe 3 by little ports valve), the water with hydrostatic force is only full of in the B of chamber, be connected and pressure equilibrium with chamber A by barrier film, make deluge alarm valve be in closed condition.During demonstration, first shut electromagnetic valve 11, and make deluge alarm valve 1 be in water-filling closed condition, now deluge alarm valve group is in quasi-operating status; Then open solenoid valve 11, connect atmospheric pressure by the transmission tube 10 be connected with chamber C, due to the reliever effect of import in the C of chamber, the pressure in the C of chamber is sharply declined; When the pressure ratio pressure of supply water in the C of chamber low to certain value time, in deluge alarm valve 1, the flap of compartment A and chamber B is opened by pressure of supply water, then water flows into system side rising pipe 9 and puts out a fire.Meanwhile, current enter the delayer 5 be attached thereto through filtrator 4, and current are full of delayer 5 to confirm the generation of fire, then flow through the pipe network be connected with delayer 5, starting pressure switch 8 and warning water system 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
