Description

Colliery tunnelling tunnel is with quick-witted water curtain Technical Field The utility model belongs to the technical field of fluid control, and particularly relates to a coal mine tunneling roadway and machine water curtain. Background The traditional design generally directly controls the on-off of a waterway through a single ball valve or a gate valve, if the valve is accidentally closed due to vibration, false touch and the like, the water curtain is invalid, for example, the separation effect is lost in a fireproof scene, if the valve is blocked and can not be closed, the passing requirement of personnel can not be met, the single risk of 'non-on-off' exists, if the traditional single-control valve adopts welding or fixed connection, the water is required to be shut down integrally during maintenance, the water curtain can not be maintained in sections, and if the tightness of a connecting structure is insufficient, water is easy to leak or is easy to loosen due to vibration influence, and the water curtain is easy to run away.
