TH7502B - Gas Leak Detection Tool from Double Safety Valve - Google Patents

Abstract

The Double Safety Valve Leak Checker will show gas leaks only if soapy water is used as a means of facilitating bubbles while checking the instrument. This can indicate that the leakage is caused by any part of the double safety valve valve to facilitate the repair of the leaking valve. In addition, the valve layer can be repeatedly checked repeatedly to ensure confidence and make decisions with ease and speed.

Claims (4)

1. The gas leak detection apparatus from the double safety valve consists of a housing (1) with a cylindrical metal shape similar to a bicycle bellows device. That is, the cylinder (5) is fitted with the rubber piston (3), the P and the connecting rod (8) are characterized by a long round shaft attached to the center of the rubber piston (3) with two sides of the cylinder cover (5). Is the top (6) and the top and bottom (7). Inside the cylinder (5) there is a spring (4) between under the rubber piston (3) and inside the bottom (7) and serves to bend the piston to slide up and stick the inside of the top. (6) all the time with a connecting rod (8) in the top center (6) with an air coupling (2) on the side of the top (6) to bring the air power from the air source such as an air pump to push it. The rubber pistons (3) to operate, the lever (22) and the steering knobs (23) are opposite and installed on the side of the top (6), as well as the air coupling (2) according to Figure 4.To do The function of controlling the opening-closing of the air valve (13) in the middle of the outside of the top (6) has a vent hole (9) left from the system below (7) looks like a thick round metal plate with the top next to the cylinder In the center, drill a hole for the connecting rod. (8) pass through On one side there is a push button (10) that controls the spring mechanism (11) to work, slide the lock wedge (14), lock the connecting rod (8) in the isthmus area (15), the far end which is connected to the bottom thick round metal plate (7). It is a rectangular plate with a groove (12), like a horseshoe, to be attached to the groove (16) of the gas cylinder valve. (24) The end of the connecting rod (8) reduces the shaft size to two sizes, reducing the shaft size (21) and reducing the shaft (25), which is opposite the valve flap (24) and is the valve stem pusher (19). To check by steps when pushing the force (22) according to Fig. 2. The air from the source, which is connected to the hose, this leak detector has a pneumatic joint (2) pushing the rubber piston. (3) Sliding the spring pressure winch (4) causes the connecting rod shaft (8) to slide down too, but is locked down by the locking wedge. (14) Isthmus area (15) The end of the shaft size (21) is pressed onto the valve stem (19) as shown in figure. 3. With soapy water injected into the pressing area, if the rubber ring (18) the bottom of the valve (24) is in good condition, does not leak, will not produce bubbles and When the button (10) is pressed as shown in the figure 4.Forcing the mechanism (11) to loosen the connecting rod shaft locking wedge (8), the connecting rod shaft (8) will continue to slide down and will stop when the shoulder (20), which is in the middle of the connecting rod shaft (8), sits. The platform is on the inside of the bottom (7), the end of the shaft reduction area (21) continues to push the valve stem (19) and move down accordingly, reducing the shaft size (25) down to fit. Rubber ring (17), top of valve (24) If the rubber ring (17) is torn, leaving a gap between the plunger shaft. (8) with the reduction shaft (25) will cause the soap bubble to pop up eventually.
