Beschreibung
Zusammenfassung:	The utility model provides a safety stop valve which comprises a valve body, a valve element and a sliding valve are installed in the valve body, and the outer diameter of the valve element is the same as the outer diameter of the sliding valve. The slide valve is in sliding fit with the inner wall of the valve body mounting cavity, the slide valve and the valve element are supported through a spring, and a retainer for limiting the slide valve is arranged on the inner wall of the valve body; a liquid passing cavity is formed in the valve element, a plurality of liquid passing holes are formed in the side wall of the valve element, a throttling hole is formed in the sealing bottom of the valve element, a liquid passing opening communicated with an inner cavity of the valve body is formed in the sliding valve, and the inner diameter of the liquid passing opening is smaller than the outer diameter of the sealing bottom, so that when the sliding valve is tightly attached to the valve element, medium flow between
