Abstract

PURPOSE:To prevent a gas leakage following the removal of the screw plug of a pressure detecting plug, by making a constitution in which a stopper device to limit the rotating angle of the operating shaft of a closer in a specific scope in a stopper function released condition, when the shaft is inserted to a fitting hole provided to a member moving together with the operating shaft. CONSTITUTION:When a closer 2 is fully closed, one side of the vertical piece 34 of a stopper ring 33 is brought into contact with one side 66 of the first arc 62 of a locking plate 6, and the closer 2 is made rotatable to open and close in the scope 90 deg. counterclockwise form the fully closed condition. In this case, by rotating an operating knob 7 counterclockwise in the direction pressing in the knob 7, the closer 2 is fully opened. And in the fully opened condition in which the operating knob 7 is rotated clockwise from the fully closed condition of the closer 2, a pressure detecting condition in which a pressure-detecting plug 12 and an auxiliary hole 22 coincide is made, but, in order to enable the rotation, a stopper function is made in a released condition. That is, the shaft 32 of a screw plug 13 is pressed in a fitting hole 31 provided to the operating knob 7, and a movable claw 35 is positioned in a tube 10.

Then, at the fully closed position of the closure (2), one side of the upright piece (34) of the stopper ring (33) abuts one side (66) of both ends of the first arc (62) in a counterclockwise direction. . Due to the action of the stopper device (3) described above, it is opened and closed in a range rotated 90 degrees counterclockwise from this state. At this time, at the fully closed position of the closure (2), the clutch is closed. The upper surface of the plate (5) is in contact with the locking plate (6) and the upright piece (34)
And the one side (66) are in contact with each other, the counterclockwise rotation is prevented. If the operating knob (7) is pushed in by a certain stroke from this state, the tip of the upright piece (34) will be located below the locking plate (6), and while keeping this state, the operating knob (7) is turned upside down. When it is rotated clockwise, the closure (2) can be rotated to the fully open position.
In this way, the pushing and turning mechanism is realized. In this pushing state, the bending tongue (37) provided at the lower end of the movable claw (35) approaches the bottom surface (17) of the excision region (16), so that it does not come into contact with it. The excavation depth of this excision region (16) is set to a predetermined depth. That is, the cutting depth is set to be slightly deeper than the most lowered position of the bending tongue piece (37) when the operating knob (7) is pushed in.

When the closure (2) is rotated from the fully closed position to the previous position, the pin (56) causes the other step portion of the third arc (65).
It moves to the (65b) side, but since the angle from the point (S 1 ) to the stepped portion corresponds to the angle from the fully closed position to the fully opened position of the closure, this pin (56 ) Does not hinder the opening / closing rotation during normal operation. Shaft (32) and fitting hole (31)
Is set to a circular cross section in this embodiment, but if it is set to a T-shaped cross section or a complicated cross section other than this as shown in FIG. 11, the screw plug (13) Shaft (3
Since the stopper device (3) cannot be set to the stopper function released state by members other than 2), it is not set to the combustion pressure detection state or the primary pressure detection state by mischief. Further, in the above-mentioned embodiment, the fitting hole (31) is provided in the operation knob (7), but the fitting hole (31) is provided in the other part that integrally rotates with the closure (2). Needless to say, the stopper device (3) may have a structure other than the above-mentioned embodiment. For example, a pin that is slidably accommodated in the operation knob (7) in the horizontal direction and is biased in the protruding direction exerts a stopper function in relation to the tubular portion (10), and this pin is used as the shaft portion (32). Alternatively, the stopper function may be released by pushing in.
