Fire extinguisher valve

The utility model aims to provide a fire extinguisher valve which is simple in structure, convenient, durable and good in sealing performance. The technical scheme includes that the fire extinguisher valve comprises a valve body, a valve stem, a pressing handle, a lifting handle, a safety pin and a rivet. The upper end of the valve stem is linked with the valve body hermetically and movably via a sealing ring. An upper cone and a lower cone opposite in direction are arranged at the tail end of the valve stem. An angle of a conical face of each of the upper cone and the lower cone fits with that of a conical face of the corresponding position of the valve body. The rubber ring contacts with the conical face of the valve body. The lifting handle is inserted into the valve body via an insert groove and fixedly linked with the valve body. A positioning seat is arranged in the front section of the pressing handle. An arc groove is formed in the positioning seat and corresponds to the top end of the valve stem in position. The fire extinguisher valve has the advantages of good sealing performance and capability of prolonging service life of a fire extinguisher; abrasion to the valve body can be reduced effectively by the aid of the added rubber ring, so that service life of the valve is prolonged; by means of inserting the lifting handle into the valve body via the insert groove and fixedly connecting the lifting handle with the valve body, the lifting handle is enabled to bear higher weight.
