Abstract
The utility model discloses a fire protection water tap automatic control device, which relates to an automatic control device using the low boiling point liquid serving as a temperature-sensing element serving as a release device. The device adds a tower-shaped tube (2), a corrugated tube (6) with a sharp needle (5), a liquid storing bottle (9) for storing the low boiling point liquid and an outer sleeve tube (10) on the ordinary fire protection water tap. The automatic control device adopts the low boiling point liquid serving as the temperature-sensing element, so the automatic control device has simple structure and easy manufacture; the temperature-sensing element has small thermal inertia and quick response.
Description
The utility model belongs to the control device of fixed in position fire hydrant, and referring more particularly to low-boiling point liquid is that temperature-sensing element is as the automaton that discharges device.
At present, existing automatic fire control tap utilizes fusible alloy to operate as temperature-sensing element, and its weakness is that thermal inertia is big, thereby low-response, and the manufacturing difficulty of valve body, is difficult for promoting the use of.
Task of the present utility model is to propose a kind of low-boiling point liquid that utilizes to trigger release as temperature-sensing element, and simple structure is the fire hydrant automaton of system easily.
Automaton described in the utility model is to increase megatron on the water inlet pipe of the tap that common fire-fighting is used, the bellows of band prong, contain the reservoir and the outer tube of low-boiling point liquid, one end of megatron is connected with above-mentioned water inlet pipe, the end face of the other end covers the rubber-like film, there is rigidity cover with holes the outside of film, and have at least a hole to match on the cover with above-mentioned prong, this bellows is fixed on the megatron by support, overcoat is placed in above-mentioned object wherein, and be external opened type, the reservoir of containing low-boiling point liquid places the uncovered outside of outer tube, there is a conduit to lead to the afterbody of the ripple mouth of pipe on it, and communicates with it.
The operation principle of automaton described in the utility model is as follows:
When breaking out of fire, indoor temperature rises, low-boiling point liquid boiling in the reservoir, the gas that produces enter in the bellows along being attached thereto the conduit that connects, the air pressure of above-mentioned gas makes the bellows elongation, thereby advance the prong on bellows top to go up corresponding hole by cover, puncture elastic membrane and cause contraction, so the water in the megatron promptly ejects by cover upper water-out hole.
Accompanying drawing 1 is the longitudinal sectional drawing with fire hydrant of above-mentioned automaton.
Now be described further in conjunction with 1 pair of concrete structure of the present utility model of above-mentioned accompanying drawing.
Water inlet pipe (1) at common fire hydrant increases megatron (2), the end of one end of this megatron (2) and water inlet pipe (1) is threaded, the end face of its other end covers has the mouth of pipe that flexible film (3) seals megatron (2), and water can not leaked. There is a rigidity cover (4) with holes the outside of above-mentioned elastic membrane (3), and its effect is to make elastic membrane (3) be unlikely overinflation under the pressure of water and break. The head portion of above-mentioned rigidity cover (4) has a hole at least and is fixed on the bellows supercentral prongs of (6) one ends (5) and cooperatively interacts, the other end of this bellows (6) is fixed on the support (7), this support (7) is fixed by bolts on the megatron (2), outer tube (10) is threaded with megatron (2); And with above-mentioned object cover therein, the top of this outer tube (10) is external opened type, the reservoir (9) that low-boiling point liquid is housed places the uncovered outside of outer tube (10), there is the afterbody center ， And that a conduit (8) leads to bellows (6) to be interconnected with it on this reservoir (9).
Above said elastic membrane (3) can be whippy rubber membrane, said rigidity cover (4) can be manufactured with materials such as copper, stainless steel or rustless alloys, low-boiling point liquid in the said reservoir (9) can be carbon tetrachloride (boiling point is 48 ℃), also can be alcohol (boiling point is 78 ℃) etc., the conduit (8) that said reservoir (9) and being attached thereto connects can be made of the good material of heat conductivility, and said bellows (6) can be manufactured with rubber or flexible plastic.
The utility model is to use low-boiling point liquid as temperature-sensing element, and its advantage is that thermal inertia is little, and response is fast. The said automaton simple structure of the utility model, easily making are convenient to promote.
Specify embodiment of the present utility model below in conjunction with accompanying drawing 1:
When breaking out of fire, temperature on every side rises to about 50 ℃, carbon tetrachloride in the reservoir (9) promptly seethes with excitement, the gas that is produced enters in the bellows (6) by conduit (8), the pressure of gas makes bellows (6) elongation, the prong (5) that is fixed on bellows (6) center, top is pushed into, go up hole with matching by cover (4) and puncture rubber membrane (3), this rubber membrane (3) produces elastic shrinkage, the water of megatron (2) lining promptly sprays by the mouth of pipe of the hole on the cover (4) by the outer tube (10) that opens wide, thereby finishes task described in the utility model.
Claims (5)
1, a kind of fire hydrant automaton, it is characterized in that on the water inlet pipe of the tap that common fire-fighting is used, increasing megatron, the bellows of band prong, contain the reservoir and the outer tube of low-boiling point liquid, one end of megatron is connected with above-mentioned water inlet pipe, the end face of the other end covers the rubber-like film, there is rigidity cover with holes the outside of film, and have at least a hole to match on the cover with above-mentioned prong, bellows is fixed on the megatron by support, outer tube is placed in above-mentioned object wherein, and be external open type, the reservoir of containing low-boiling point liquid places the uncovered outside of outer tube, has a conduit to lead to the afterbody of bellows on it, and communicates with it.
