Abstract
The invention relates to the technical field of valves, and in particular to a novel needle type stop valve. The novel needle type stop valve comprises a lower valve body. A horizontal gas inlet, a horizontal gas outlet and a vertical control hole are formed in the lower valve body. The gas inlet is communicated with the bottom of the control hole through a first passageway. A valve rod with the upper portion penetrating out of the lower valve body is arranged in the control hole. A valve base used in cooperation with the bottom of the valve rod for blocking the control hole is arranged in the control hole. The gas outlet is communicated with the control hole in the upper portion of the valve base through a second through hole. The upper portion of the lower valve body is connected with an upper valve body. A drive device driving the valve rod to move up and down is arranged in the upper valve body. A conical valve element is connected with the bottom of the valve rod. A valve deck used for sealing the upper valve body is arranged at the top end of the upper valve body. The novel needle type stop valve is simple in structure and reasonable in design. The valve element is used in cooperation with the valve base to block the control hole, and safety is high. A seal assembly is arranged in the upper valve body, and therefore the sealing performance of the stop valve is improved, and the novel needle type stop valve is not prone to gas leakage.
