Abstract

The utility model discloses a fireproof valve, comprising a valve body, a fluid inlet and a fluid outlet on the both sides of the valve body, a spray head screwed on the fluid outlet, a valve cap on the upper part of the valve body, a disk and a temperature sensitive control element which are arranged on the lower part of the valve body, a piston in the valve body, a push rod, and a tension spring. The utility model can be arranged on various fluid extinguishing devices. The utility model has the advantages of artful structure, good tightness, reasonable selection of materials, big spray angle. Besides, the spray angle can be adjusted arbitrarily. The temperature sensitive control element moves when the fire is occured, the valve opens automatically without any power supply and starts to spray fluid. The temperature sensitive control element is easy to replace and repair. The valve has plastic graphics decoration in shape, and has definite artistry and interesting.

Description

Fireproof valve

The utility model relates to a kind of fire-protection valve, particularly a kind of fire-protection valve that can be installed on all kinds of fluid extinguishing devices.

Fire prevention is very important in people's routine work, production and a life important measures, and valve then is a critical piece in the various firebreak devices.At present the fire-protection valve used always of people is to utilize heated liquid to expand and make its glass fragmentation faced and spray water, and its structure mainly comprises valve head, temperature-sensitive glass, caulking gum and screw etc.This fire-protection valve is if be installed under the elevated pressures, then because of the cracked voluntarily cisco unity malfunction of meeting, and uses inconvenience because of the certain limitation that can not regulate spray angle and be subjected to water channel.At present this series products is by foreign import, and also belongs to the initial stage after-product in the fire-protection valve abroad, be exactly this series products as what install recently at the Hua Lian commercial building, but its spray angle is limited, and distance also falls short of, and needs further to improve.

The purpose of this utility model is to provide a kind of fire-protection valve, can be installed on all kinds of liquid fire extinguishing devices, and spray angle is big, can regulate arbitrarily, and Open valve sprays fluid automatically when fire takes place, and without any power source.

The utility model is achieved in that a kind of fire-protection valve, comprise valve body, valve gap, temperature-sensing control element, piston, push rod, disk, extension spring and shower nozzle, the valve body both sides have a fluid input port and a fluid delivery outlet respectively, shower nozzle is spun on and is fan-shaped on the fluid outlet, the top of valve body is valve gap, the bottom is temperature-sensing control element and disk, temperature-sensing control element is positioned in the middle of valve body and the disk, and an extension spring is arranged in the element, and its end links to each other with valve body, the other end contacts with disk, one piston is arranged in the valve body, a square push rod is arranged in the piston, after temperature-sensing control element is subjected to the temperature effect, expand outwardly, push rod rises, and the valve body upper cavity pressure descends, and piston upper chamber pressure is lower than cavity pressure under the piston, therefore piston is opened, the beginning jet.

A kind of fire-protection valve of the utility model can be installed on all kinds of fluid extinguishing devices, and its shower nozzle is the fan type, spray angle is big, can regulate arbitrarily, promptly its projected area can change as required, but is not less than 70 machine angles, double end is sprayed and is not less than 150 machine angles, because of the size of local area, can select the valve of different bores for use, also can select single head or double end extinguishing device for use, have bigger flexibility, range of application is quite extensive; Automatically Open valve sprays fluid when fire takes place, and particularly observes under the lax situation and plays the self-extinguishing effect in unattended, festivals or holidays, fire prevention in the late into the night; And without any power source because fire when taking place the prerequisite of fire fighting be the powered-down system, if select for use the controlling organization of supply unit system then just to lose automatism, moreover 30 percent fire is caused by power supply.This valve is by copper alloy or aluminium alloy compression casting moulding, have sturdy and durable advantages such as anticorrosion, ageing-resistant, corrosion resistant, the valve body profile can be cast by plastics, have ornamental shape and animals and plants profile, have certain artistry and interest, can cooperate the infield, obtain effect reasonable, attractive in appearance.Because of selection rationally and structure ingenious, this valve also has good airproof performance, openability is good, convenience such as ability elevated pressures, replacing temperature-sensing control element and overhaul advantages such as simple, can be used for any stationary applica-tions or mobile occasion, for example, places such as factory, office, school, hotel, well received.

Fig. 1 is the cutaway view of the utility model fire-protection valve.

Describe the utility model fire-protection valve in detail below in conjunction with accompanying drawing.

Referring to accompanying drawing 1, a kind of fire-protection valve mainly is made of valve body 1, valve gap 12, temperature-sensing control element 5, piston 10, push rod 9, disk 7, extension spring 6 and shower nozzle 2.Valve body 1 by copper alloy or aluminium alloy through the forge hot die cast, both sides have a fluid input port 8 and a fluid delivery outlet 3 respectively, shower nozzle 2 is by copper alloy or aluminium alloy compression casting moulding, be spun on the fluid outlet 3 and be fan-shaped, the top of valve body 1 is valve gap 12, by the corrosion resistant plate punch forming, and around equably punching out go out six holes, settle rubber washer in interior week, and it is firm through row with screw 11, the bottom of valve body 1 is temperature-sensing control element 5 and disk 7, temperature-sensing control element 5 is two alloy sheets or temperature-sensitive expanding liquid element, be located opposite from the middle of valve body 1 and the disk 7, supporting valve body 1 and disk 7, disk 7 is made by copper alloy or stainless steel material, one extension spring 6 is arranged in temperature-sensing control element 5, stainless steel spring silk by 1-2mm is made, one end links to each other with valve body 1, the other end links to each other with an intermediate that links to each other with disk 7 by screw, be in the duty of tension at ordinary times, one piston 10 is arranged in valve body 1, one push rod 9 is wherein arranged, and epimere is square, and it is by valve body 1 and temperature-sensing control element 5, the upper end is fastened on the flat board in piston 10 with screw, the other end and disk 7 are connected, and push rod 9 and flat board are a valve, and piston 10 is the secondary valve, two road rubber washers 4 are housed between flat board and piston, prevent to leak.This valve profile also can be the ornamental or animals and plants profile that is made of plastics.When fire took place, temperature-sensing control element 5 was subjected to extraneous temperature rise and changes displacement, and the extension spring 6 stressed push rods 9 that make rise, and piston 10 decompression that also rises is upwards opened valve, and fluid utilizes self pressure outwards to spray automatically.
