Abstract
The utility model discloses a charging valve with double seal. The charging valve comprises a charging valve body, a valve rod, an inner seal ring, a seal cartridge, an outer seal ring, a spring pocket, a seal groove and a valve hole, wherein the valve rod is mounted inside the charging valve body; the valve rod is of a barrel-shaped structure with the valve hole which is formed in the bottom; the upper part of the valve rod is connected with the seal cartridge; the bottom of the valve rod is connected with the inner seal ring; the upper part of the seal cartridge is a convex buckle which is outwards convex; the outer seal ring which sleeves the convex buckle is arranged on the convex buckle and is used for outwards sealing an upper opening during installation; the lower half section of the seal cartridge is sleeved in the inner wall of the charging valve body in an embedding way; the seal groove which is inwards concave is formed in a lower opening of the charging valve body and is used for externally sealing the lower opening during installation; the spring pocket sleeves the valve rod; one end of a spring is fixed to the seal cartridge; the other end of the spring is fixed to a position where the charging valve body is in contact with the valve rod. Compared with the prior art, the charging valve with double seal has the obvious advantages that the structure is simple, the use is convenient, and the sealing property of the charging valve is effectively enhanced.
Description
Technical field
The present invention relates to the charge-filling valve of a kind of charge-filling valve, particularly a kind of double seal.
Background technique
At present, generally will there be charge-filling valve in the place joining at two pipelines of fluid, and the general seal arrangement of current charge-filling valve is all single sealing, one is that seal arrangement is positioned at charge-filling valve outside, a kind of is the inside that seal arrangement is positioned at charge-filling valve, these two kinds of charge-filling valves are due to the sealing single leak case that all easily causes fluid, particularly some harmful gas or liquid, and leak case all can cause great injury to human and environment.
Summary of the invention
The purpose of this utility model is just to provide a kind of charge-filling valve of double seal, its simple in structure, easy to use and effective sealing that strengthens charge-filling valve.
A kind of charge-filling valve of double seal, comprise charge-filling valve body, valve rod, inner seal ring, stuffing box gland, exterior seal ring, spring housing, seal groove and valve opening, described valve rod is arranged on charge-filling valve body interior, valve rod is that bottom is with the tubular structure with valve opening, valve rod top is connected with stuffing box gland, and bottom is connected with inner seal ring; The top of described stuffing box gland is that the protruding of evagination buckled, the protruding exterior seal ring that is coated at protruding button of buckling, external sealed suitable for reading during for installation, embedded being socketed with charge-filling valve inner body wall of lower semisection of stuffing box gland, the lower opening of charge-filling valve body has the seal groove concaving, the end opening external sealed during for installation; Described spring housing is sleeved on valve rod, and spring one end is fixed on stuffing box gland, and the other end is fixed on the place that charge-filling valve body contacts with valve rod.
Compared with prior art, significant advantage of the present invention is: simple in structure, the easy to use and effective sealing that strengthens charge-filling valve.
