本発明はガスコンタに係り、符に閉子m動囲のグリース

。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of M Tojo] The present invention relates to a gas contactor, and relates to a gas cock which is designed to have a grease retaining ability with a closed valve movement range of m.

たるようになっていない。Conventionally, in gas cocks where the sliding surface of the closing member is conical, the taper of one conical surface is generally 1° to 30°, so that the closing contact surface of the cock body and the closing member taper once match. ◎ [Problem that the invention attempts to solve and 1'] However, it is impossible to machine the circle #i surface of the closure and the contact direction of the closure of the main body so that they match. ,
In reality, the closure 011 t87 of the cock body (2) hits the upper part of the J sea closure 11) shown in Figure 43 (α),
The f side hits J5 in the same figure (b), and the sliding surface does not hit evenly.

An error of λ to 3μ is included at the top or bottom of the rotation. However, the opening/closing durability test H of the one-sided gas hook mentioned above
If this is done, the opening/closing operation torque will increase after 10,000 to 20,000 cycles, and in the worst case, opening/closing operations will become impossible and there is a risk of gas leakage.

Grease on the sliding surface of the J sea urchin abutment 9 side shown in Figure 9 (4)

きない。The reason for this is that excess grease is scraped off by the gas passage hole (6) on the circumferential surface of the central part of the sliding concave, and then grease (4) is applied and supplied to the sliding surface during opening and closing operations. The grease is retained, and the sliding motion on the opposite side of the one-sided contact is retained by the 2 to 3μ slit created in the IfIwJ rotation. Since the mental energy is concentrated, the grease (4) is discharged upwards and becomes depleted.In other words, the grease cannot be held evenly.

ある。The 100 yen of the present invention solves the conventional problems described in θσ and has grease retention performance? For this purpose, the periphery of the closed dust cone or a part of the closed contact 4 of the cock body, that is, the central surface corresponding to the closed gas passage hole, is raised all around and the upper and lower parts of the raised Q concave are coated with grease. Hold? @Gap was formed.

グリースか保持される。According to the present invention configured as described above, excess grease is scraped off into the gas passage hole on the central conical surface of the sliding surface, and grease is applied and supplied to the sliding direction during opening/closing operations. Grease is always retained. Furthermore, in the upper circular m110 and the lower conical surface of the N# surface, there is a gap of K to Sμ with respect to the central circumferential surface, so that grease is retained in these portions.
