Abstract

The device prevents overfilling of gas. With a case, which is within the case It is the address of the piston. Which at the top of the body of the case in the area at the bottom of the top end that is There are a number of holes around the threads to serve as a channel for gas to flow into and out of the gas cylinder and the area. The top of the housing is a pressure relief hole. In which the space between the top of the piston and the interior of The lower body of the housing is covered with a spring, and at the center of the piston is a channel where Within the area at the bottom of the piston cavity there is a spring attached. With at the very bottom end of The body, which is an internal thread, is attached to the first body of the float. Which at the The bottom of the first part of the float is a pair of legs that fit into the upper area. Of the second part of the body of the float with mounting bolts Which the second part of the float will be formed into a canine The middle is the point to move to the lower end of the push rod of the pedal and on the two sides of the central can be the lateral fangs that move up to the area. Both lateral edges of the first part of the float Which at the bottom of the second part of the body of the child Float will be a float stem. Where the lower part of the body, the second part of the float is a float

Claims (5)

1. The overload protection device consists of a hollow cylinder-like housing (1). The upper end of the housing (1) is an external thread to fit the internal threaded bottom surface of the lower body. Cooking gas valve And the bottom end of the case (1) is an internal thread to wear on the body. The first part of the float (2), in which the upper body (3) of the body (1) in the area at the bottom of the The upper end is threaded into a number of holes (6) around to serve as a channel for gas to flow in and out. To the gas tank and at the top of the lower body (4) of the housing (1) is a pressure relief hole (13), the piston (5) is installed inside the housing (1), where the upper part of The piston (5) is approximately the same size as the upper body (3) of the housing (1) so that it can fit properly into the upper body (3) of the housing (1). And at the center of the piston (5) is a cavity (10) for gas to flow inward, the space between the top of the piston (5) and the interior of the lower body (4) of the housing (1) will There is a spring (7) covered by the connection between the cavity (10) of the central area and the The lower part of the recess (10) is the shoulder (11) for the spring support (12), characterized by that at the bottom end of the housing (1), the internal thread is attached to the first part of the body. Float (2) in which the core of the first part of the float (2) is hollow, with the inside of the top of the body, the first part of the float (2) is covered with a pusher (15), which At the bottom of the push rod (15) is the push rod (17), a cylindrical shape that extends the lower end out. The first part of the float (2) is the two legs (18) to be worn on the upper part of the second section of the float (19). ) With mounting bolts (24), in which the second body of the float (19) is formed into a central canine (20) as a point to To move to the lower end of the push rod (17) of the pusher (15) and at both sides. The two sides of the central canine (20) are the lateral fangs (21) that move upward and push against the edge. Both sides of the first part of the float (2), the lower part of the second section of the float (19) is the float rod (22). A float (19) will be a float (23) fixed to the float rod (22) by means of fastening (24). 2. The device prevents overfilling of gas. According to claim 1, the upper body (3) of the case (1) is smaller than the lower body (4) of the case (1). 3. The device prevents overfilling of gas. According to claim 1 or 2, in which the upper end of the piston (5) is covered with a rubber O-ring (8) to prevent gas leakage. And at the lower end of the piston (5) there is a rubber O-ring (9) covered to prevent gas leakage as well. 4. The device prevents overfilling of gas. According to any claim 1 to 3, the cavity size (10) of the top of the piston (5) will be the smallest and then larger at the area. The center of the piston (5) and the opening (10) are the largest at the bottom of the piston (5). 5. The device prevents overfilling of gas. According to any claim 1 to 4, where between the housing (1) and the body of the first part of the float (2), a rubber O-ring (14) is covered to prevent gas leakage.
