Abstract
The utility model relates to an alarming safety valve used for pipeline gas, which is mainly composed of a valve body and an alarm, wherein the valve body is provided with a ball valve and an electromagnet inside, and a rod of the ball valve is provided with a torsion spring and a stop rod. The utility model not only has the function of audible and visual alarm and the function of automatically closing gas, but also has a manual device and an automatic device. Therefore, the utility model has the advantages of particularly easy use, and safe and reliable performance, being an ideal safety protective device for pipeline gas.
Description
The utility model relates to a kind of piped gas alarm safety device.
Along with the raising of living standards of the people, the use of urban duct coal gas is more and more universal.Yet,, and cause the casualties of gas leakage and the accident of property loss also to occur repeatedly because of the reasons such as aging or improper use of gas range.In order to prevent gas leakage, the accident of stopping takes place, and mode commonly used at present is that warning device to harmful gas is installed.Though it is this warning device to harmful gas has certain effect, under a large amount of situations of leaking of nobody or coal gas, powerless at the scene.
In view of the above problems, the purpose of this utility model provides a kind of existing automatic warning function, and automatic closing function is arranged again, and can be manually, the gas alarm safety valve that develops simultaneously automatically.
The utility model is achieved like this: it is made up of safety valve and alarm two-part.Ball valve body, electromagnet, valve rod and torsion spring and push rod etc. are installed in its valve body.What be provided with in the alarm smells photosensitive elements, is used for perception gas leakage, and connects power supply, DM work.During work of electromagnet, attract link stopper, be installed in torsion spring on the valve rod and can promote valve rod and close ball valve voluntarily, thereby can stop gas leakage effectively, prevent the generation of accident.
Concrete structure of the present utility model is as shown in drawings:
Fig. 1 is a form structure schematic representation of the present utility model
Fig. 2 is the cut-away view of the utility model valve body part
Below in conjunction with accompanying drawing, specific embodiments of the present utility model is elaborated:
The gas alarm safety valve is made up of safety valve 1 and alarm 2.Safety valve 1 and alarm 2 are connected as a single entity by lead.Alarm 2 adopts commercially available prod, and is provided with and smells photosensitive elements as the sensing control element.On valve body 13, be provided with ball valve 3, on ball valve bar 11, be provided with torsion spring 4 and lever 10, in valve body 13, be provided with electromagnet 8.The lead-in wire of electromagnet 8 is by being connected with power supply by the contact-making switch of smelling photosensitive elements control.In the both sides of electromagnet 8, be provided with stand 7.In the stand 7, be provided with spring 6 and washer 5.Torsion spring 4 on spring 6 and washer 5 and the valve rod, the lever 10 common open and close states that constitute ball valves.In addition, on valve body 13, also be provided with hand push-rod 12, the end of ball valve bar 11 is provided with handle 9, and the two is used for the manual control to ball valve.
Working method of the present utility model is achieved like this:
The valve body of safety valve is installed on the gas pipe line in advance, pressing hand push-rod 12, compression washer 5 makes lever 10 leave washer 5, and handle with sleeve 9, opens ball valve 3.Then, loosen hand push-rod 12, the spring 6 in the stand 7 makes washer 5 returns, and blocks the lever 10 on the ball valve bar.At this moment, ball valve 3 is in normally open.When the content that gas leakage or indoor coal gas and CO (carbon monoxide converter) gas take place reaches finite concentration, smell photosensitive elements work, when sending sound, light and reporting to the police, and connect the power supply of electromagnet.At this moment, electromagnet produces magnetic force, attracts washer 5, washer 5 pressure springs 6, and lever 10 leaves washer 5, and ball valve bar 11 cuts out ball valve 3 automatically under the twisting force of torsion spring 4, thereby reaches the purpose of cutting off coal gas.
If, being in power failure, electromagnet can't be worked, and then can pass through pressing 1 hand push-rod 12, and compression washer 5 makes lever 10 leave washer 5, and torsion spring 4 can be closed ball valve 3 automatically, reaches the purpose of cutting off coal gas equally.
The utility model is simple in structure, and is easy to use, and reliable performance is a kind of desirable safety protection device.
