Abstract

An opening-delaying throttling stop valve comprises a valve body, a valve element and a valve rod. An output channel and a through hole communicated with an inner cavity of the valve body are arranged on the valve body respectively. An input channel of the valve body is communicated with the through hole. The valve element is arranged in the inner cavity. A penetrating hole is formed in the valve element. The upper end of the valve rod penetrates through the through hole and the penetrating hole in sequence and moves up and down relatively in the through hole and the penetrating hole. A valve rod cap is connected with the upper end of the valve rod. A limiting structure is arranged between the valve element and the valve rod cap. A spring is arranged on the limiting structure in a sleeved mode. The limiting structure moves synchronously along with the valve rod. When the valve element seals a feeding opening in the combining portion of the through hole and the inner cavity, the lower end of the limiting structure abuts against the upper surface of the valve element, the penetrating hole is sealed, and the spring is in a compressed state. The opening-delaying throttling stop valve lowers slurry flowing-in speed and accurately controls slurry flow, the opening-delaying throttling stop valve has the advantages of being high in sensitivity, good in accuracy and high in working efficiency, and produced products are good in quality.

Description

technical field [0001] The invention relates to the field of coating for manufacturing lithium batteries, in particular to an extended throttle cut-off valve applied to a fast gap feeding device. Background technique [0002] A valve is a control device for a fluid pipeline. Its basic function is to connect or cut off the flow of the medium in the pipeline, change the flow direction of the medium, adjust the pressure and flow of the medium, protect the normal operation of the pipeline equipment, and also have the function of shunting or overflow unloading. pressure and other functions. With the continuous development of modern industry, the demand for valves continues to increase, and the requirements for the accuracy of valves have also increased. [0003] Especially in the coating industry of manufacturing lithium batteries, in order to make the quality of the products produced by the coating machine better and make the products more competitive in the market, it is neces...
