Abstract
The utility model discloses a balance type vacuum plunger valve which relates to a valve, in particular to a plunger valve. The balance type vacuum plunger valve comprises a valve body, a plunger, a hole stand, a graphite sealing ring, a valve rod, a valve cover, a graphite filler, an oil ring, a plug screw, a gland, an upper bracket, a plane bearing, a valve rod nut and a hand wheel. The valve body is internally provided with the hole stand, the valve base of the hole stand is internally provided with the graphite sealing ring, the plunger is installed inside the graphite sealing ring, and the upper end of the plunger is connected with the valve rod. The valve cover is installed at the upper part of the valve body, and the gland is installed at the upper part of the valve cover. The upper bracket is installed at the upper part at the outer side of the gland. The valve rod is arranged in the valve cover, the gland and a hole of the upper bracket. The graphite filler and the oil ring are arranged between the valve rod and the gland. The plug screw is installed in an oil hole on the lateral surface of the gland, and the plane bearing is installed between the valve rod and the upper bracket. The valve rod nut is installed on the plane bearing and is matched with the valve rod in a threaded way, and the hand wheel is installed on the valve rod nut. The balance type vacuum plunger valve solves the problem that liquid is leaked caused by infirm sealing of the traditional like product.
Description
Technical field
