Abstract
A valve comprises a hand wheel, a locking operation member inserted in a space of the hand wheel and a fixing locking member. The valve is locked when the locking operation member is combined with at least partial of the fixing locking member, the valve is unlocked when the locking operation member is separated from the fixing locking member, the locking operation member rotates in response to rotation of the hand wheel while the locking operation member is inserted in the hand wheel, and the fixing locking member is used for locking of the valve with fixed.
Claims7
A valve comprising:
- a hand wheel;
- a locking operation member inserted in a space of the hand wheel;
- and
- a fixing locking member,
- wherein the valve is locked when the locking operation member is combined with at least partial of the fixing locking member, the valve is unlocked when the locking operation member is separated from the fixing locking member,
- the locking operation member rotates in response to rotation of the hand wheel while the locking operation member is inserted in the hand wheel, the fixing locking member is used for locking of the valve when fixed,
- at least one projection is formed on a part corresponding to a side of the fixing locking member of inner surfaces of the locking operation member but is not formed on the other part of the inner surface, a locking projection is formed on an outer surface of the fixing locking member,
- the projection of the locking operation member is separated from the locking projection of the fixing locking member when the locking operation member moves in a direction of a center of the hand wheel through a space formed on a side of the hand wheel, thereby unlocking the valve,
- the projection of the locking operation member interlocks with the locking projection of the fixing locking member when the locking operation member moves in an outward direction of the hand wheel, thereby locking the valve,
- a hole is formed on a part of the locking operation member, and at least part of a locking member is inserted in the hole to lock the valve while the locking operation member is projected outside the handwheel,
- wherein a projection supporter is formed at a rear part of the projection of the locking operation member to support the projection and an incision section is formed on a part of the projection supporter.
A locking operation member used for locking a valve comprising:
- a body;
- and
- an insertion member extended longitudinally from the body,
- wherein a space is formed in the body, projections are formed on a part of an inner surface of the body, but are not formed on the other part of the inner surface of the body, the locking is achieved by combining the projections with locking projections of an external locking member,
- unlocking is realized when the projections are separated from the locking projections of the external locking member, and
- the combining or the separating of the projections and the locking projections are determined by moving of the insertion member,
- the projections are formed on a part corresponding to a side of the external locking member of inner surfaces of the body, the locking projections are formed on an outer surface of the external locking member,
- the projections of the body are separated from the locking projections of the external locking member when the insertion member moves in a direction of a center of a hand wheel through the space formed in the body, thereby unlocking the valve,
- the projections of the body interlock with the locking projections of the external locking member when the insertion member moves in an outward direction of the hand wheel, thereby locking the valve,
- a hole is formed on a part of the insertion member, and at least part of a locking member is inserted in the hole to lock the valve while the external locking operation is projected outside the handwheel,
- wherein a projection supporter is formed at a rear part of the projection of the external locking member to support the projections and an incision section is formed on a part of the projection supporter.
