Abstract
Provided is a pressure-relief water-break type safety valve. At the time of pressure-relief protection, a water supply source is cut off simultaneously in good time so as to avoid long-time pressure-relief draining on the condition that self-pressure of water supply is too high. The pressure-relief water-break type safety valve has the function of double protection. A pressure-relief signal generating device is disposed at the position of a pressure-relief port of a valve body. The pressure-relief signal generating device consists of a pressure-relief sealing gasket, an ejector rod, an unloading spring, a pressing block, a contact carrier, an elastic piece contact, a static contact and a power supply. An electromagnetic water-break mechanism which is disposed on a water entry channel of the valve body consists of a coil, a sliding electromagnet, a fixed electromagnet, a sliding piston, a sealing block and a restoring spring. When the safety valve does not relieve pressure, no pressure-relief signals exist, the electromagnetic water-break mechanism on the water entry channel is not powered on and in an open state, and normal water entry is not affected. When the safety valve relieves pressure, the pressure-relief signal generating device sends out an electric signal, and the electromagnetic water-break mechanism is powered on and closed so as to cut off the water entry channel of the valve body.
Description
Technical field
The utility model relates to a kind of pressure protective device that when pressure release, can turn-off supply channel, especially presses when excessive when supply channel, reduces hydraulic pressure with the pressure release mode, turn-offs the safety valve that supply channel is protected simultaneously rapidly, belongs to household electrical appliance technical field.
Background technique
Safety valve generally is applied to the pressure protect of container or pipeline, at present, and the safety valve that uses on the market; Its pressure release mode mostly adopts the structure of the straight drain charge formula of spring; Normally screwed by compact heap and push the drain charge spring, the elastic force of drain charge spring back generation by compression acts on the push rod, and the pressure release sealing gasket is housed on the push rod; Under the effect of elastic force, the pressure relief opening sealing on pressure release sealing gasket and the valve body.Depress at normal water, safety valve will can not produce the pressure release draining, and when container or pipeline road produce excessive hydraulic pressure; The pressure of water is greater than the elastic force of drain charge spring, and hydraulic pressure can make pressure release sealing gasket and push rod move backward, and the pressure release sealing gasket loses seal action; Safety valve is opened the pressure release draining; To reduce the pressure of water in container or the pipeline, after hydraulic pressure reduced, safety valve cut out again.
Obviously, this safety valve is highly effective to protection container and pipeline, and under pressure of supply water just commonly used, it is the short time that safety valve is opened pressure release, and the water yield of discharge is also very limited, and as long as people are guiding a little.But when pressure of supply water itself is too high, the fatal shortcoming of the straight drain charge formula of this spring structure also will fully come out, and safety valve just as the bleeder coke of long-time unlatching, is discharged a large amount of water and can be caused the loss that is difficult to expect to people after opening decompression protection.Especially in China city; Because a large amount of high buildings all adopts the mode of secondary water-supply; The higher ten minutes of pressure of supply water is general, is one ten Frequently Asked Questions so safety valve is opened the pressure release draining, and the big water gaging of discharge possibly soak article such as indoor furniture, electrical equipment; Light then cause people's damage to property, heavy then jeopardize personal safety.
Summary of the invention
In order to overcome the deficiency of existing safety valve; The utility model provides a kind of pressure release formula safety valve of cutting off the water supply; This pressure release formula safety valve of cutting off the water supply carries out effective decompression protection when can not only be to container or pipeline pressure too high, and in pressure release, in time cuts off resource of water supply; Avoid owing under the too high situation of pressure of supply water itself, open the problem of pressure release draining for a long time.
The utility model solves the technological scheme that its technical problem adopted: at the pressure relief opening place of valve body, constitute a pressure release signal occurrence device by pressure release sealing gasket, push rod, drain charge spring, compact heap, contact carrier, shell fragment contact, fixed contact, power supply, it is characterized in that: the drain charge spring screws extruding by compact heap; The elastic force that produces acts on the push rod, makes push rod that pressure release sealing gasket and pressure relief opening are compressed sealing, shoots sheet contact and fixed contact in the contact carrier of push rod end; The shell fragment contact is connected with an electrode of power supply; When the not pressure release of formula safety valve was cut off the water supply in pressure release, push rod can not produce displacement, and shell fragment contact and fixed contact are in off state; When the pressure release of formula safety valve is cut off the water supply in pressure release; Push rod outwards produces displacement, and it is closed to promote shell fragment contact and fixed contact, produces a closure signal; On the intake tunnel of valve body; Constitute the electromagnetism mechanism of cutting off the water supply by coil, slip electromagnet, fixed electromagnet, sliding piston, sealing block, Returnning spring; It is characterized in that: the lighting outlet of coil is connected with another electrode of fixed contact and power supply respectively, constitutes a complete working circuit, when the coil no electric circuit; Returnning spring promotes sliding piston, makes the intake tunnel of valve body be in open mode; Behind coil electricity, the electromagnetic force of generation makes the slip electromagnet slide to fixed electromagnet and adhesive, behind the suction-combining force compression reseting spring of generation sliding piston is moved forward, and makes the intake tunnel of sealing block valve body.
When container or pipeline pressure just often, the pressure release formula safety valve of cutting off the water supply is not opened pressure release, no pressure release signal, pressure release electromagnetism on the intake tunnel of the formula safety valve mechanism of cutting off the water supply of cutting off the water supply is in open mode, does not influence the normal water inlet of container or pipeline.
When pressure release took place, because hydraulic action is on the pressure release sealing gasket, push rod compression drain charge spring outwards moved; Move the displacement that produces and make shell fragment contact and fixed contact closure, send the pressure release signal, thereby make coil electricity; Energising produces electromagnetic force makes the slip electromagnet slide to fixed electromagnet and adhesive, in this process, also can promote sliding piston and advance; And compression reseting spring, make the sealing block that is assemblied on the sliding piston close intake tunnel, cut off resource of water supply.
The beneficial effect of the utility model is, can when opening decompression protection, can close into water water source, accomplishes the effect of duplicate protection, neither influences the cut off the water supply pressure protect function of formula safety valve of pressure release, simultaneously; Also effectively avoid under the excessive situation of pipeline pressure of supply water, for a long time the problem of pressure release draining.
