| description | A four-stage depressurization regulating valve comprises a valve body with a valve cover. A valve core component is arranged in a four-stage depressurization valve base which is arranged in the valve body. The valve core component comprises a valve rod and a four-stage depressurization valve core, a valve rod is arranged at the upper end of the four-stage depressurization valve core, and a spring pin is arranged between the valve rod and the four-stage depressurization valve core. A guide sleeve seat component is arranged between the lower portion of the valve rod and the valve body. The valve rod is arranged in the valve cover, and a packing seat, a packing spring, high-pressure lower packing, high-pressure middle packing, high-pressure upper packing, a packing gland and a packing pressure plate are sequentially arranged at the upper end of the valve rod from bottom to top. The packing gland is arranged at an upper port of the valve cover, the packing pressure plate is fixedly connected with the top end of t |
