Abstract
The utility model relates to an automatic gas safety valve, and belongs to an automatically controlled safety device. The utility model is characterized in that an automatic timer is connected with a concave-convex wheel, and the concave-convex wheel is connected with a connecting board which is installed on the upper end of a push rod. The lower end of the push rod is provided with a sealing cover. The inner part of the valve body is provided with a valve stem which is connected with the sealing cover. The valve stem is provided with a spring, and the lower end of the valve body is provided with a screw plug. The utility model has the advantages of simple and compact structure, low manufacture cost, small size, convenient installation and maintenance and safe operation; the operating time is selected so as to automatically turn off a gas source and keep a burning stove in a gas-close state.
Description
A kind of coal gas automatic blow off valve belongs to automatic control safety installations.
Before the utility model was made, safety installations all was unkitted at coal gas tool gas source inlet places such as gas appliance, coal gas shower, gas heater.When gas source switch is not closed, easily produce unsafe factor, casualty accident constantly takes place, and directly has influence on the loss of people's life and national wealth.
The purpose of this utility model is to provide a kind of simple in structure, compact, low cost of manufacture, reliable, safe coal gas automatic blow off valve.
The utility model mainly is made up of autotimer (1), the concavo-convex wheel (2), yoke plate (3), push rod (4), sealing cover (5), valve rod (6), valve body (7), spring (9), plug screw (10).Connect from motive sealing timer (1) that concavo-convex wheel the (2), the concavo-convex wheel (2) connect yoke plate (3), yoke plate (3) is installed in push rod (4) upper end, push rod (4) lower end be equipped be equipped with in sealing cover (5), the valve body (7) valve rod (6), valve rod (6) connect on sealing cover (5), the valve rod (6) spring (9) is housed, plug screw (10) is equipped with in valve body (7) lower end.
Description of drawings:
Fig. 1 is the utility model structural front view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
Autotimer (1) main shaft connection concavo-convex wheel the (2), the concavo-convex wheel (2) connect yoke plate (3), rotation timer (1) makes yoke plate (3) action promote push rod (4), yoke plate (3) is installed in push rod (4) upper end, push rod (4) contact seal lid (5) promotes valve rod (6), valve rod (6) is installed in the valve body (7), pressure spring (9), seal ring (8) leave valve body (7) sealed mouth.Valve rod (6) connects sealing cover (5), spring (9) is housed on the valve rod (6), plug screw (10) is equipped with in valve body (7) lower end.Plug screw (10) pore air inlet is gone out by the other hole of valve body air chamber.The concavo-convex I of taking turns is often opened, and II is regularly closed, and III is often closed.
The utlity model has following advantage: 1, simple in structure, compact; 2, low cost of manufacture, volume are little, easy for installation; 3, the operating time safe and reliable to operation, selected can automatic closing gas source, make burner be in the state of holding one's breath.
