Technical field
The present invention relates to a kind of stuffing box packing, in particular, relate to a kind of integral seal filler of connecting rod-ball valve.
Background technique
Connecting rod-ball valve valve rod and ball are integrated, can not come off, and sealing is reliable, and valve is interior without the dead band, easy to clean and cleaning, and long service life is used more extensive.
Traditional connecting rod-ball valve comprises valve rod, spool and filler, described spool is arranged at described stem bottom, described filler comprises two-part, be arranged at respectively the upper and lower of described spool, make connecting rod-ball valve sealing in use, still, this split type filler misplaces easily in use and is out of shape, sealing is also bad, reveals easily.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, and a kind of difficult dislocation and distortion are provided, and seals the integral seal filler of reliable connecting rod-ball valve.
In order to solve above technical problem, the invention provides a kind of integral seal filler of connecting rod-ball valve, comprise a cylindrical body with inner chamber, described inner chamber is spherical inner chamber, the size of described ball-type inner chamber is big or small identical with the spool of described connecting rod-ball valve;
The upper bottom surface of described cylindrical body arranges a upper perforate, and described bottom surface arranges a lower perforate, described upper perforate and described lower perforate big or small identical, position correspondence;
The side of described cylindrical body arranges at least 2 side openings, be fixedly installed side ring or side panel on the described side opening, described side ring is a cirque structure, and the size of its outer shroud is identical with described side opening, and the size of encircling in it is big or small identical with the import and export of the spool of described connecting rod-ball valve; Described side panel is a round structure, and its diameter is identical with the internal diameter of described side opening.
Being further defined to of technical solution of the present invention, described side opening is 4, is uniformly distributed on the described side, wherein on 3 side openings side ring is set respectively, on the side opening side panel is set.
Further, described side opening is 4, is uniformly distributed on the described side, wherein on 2 side openings side ring is set respectively, on 2 side openings side panel is set respectively.
Further, described stuffing box packing integral die moulding.
The invention has the beneficial effects as follows: the integral seal filler of a kind of connecting rod-ball valve of the present invention, change former up and down two split type structures into whole structure, can not produce inconsistent phenomenon, and reduce potential leakage point; Interior spherical cavity is an integral body, and is tightr with the spool applying, seals more reliable; The withstand voltage height of stuffing box packing, pressure rating is brought up to 3000psi from former 2500psi; Stuffing box packing and valve rod assembling form one, dismounting, cleaning and easy to maintenance; The direct die forming of integral seal filler, technology capability is good, and simple in structure, and is easily manufactured, and cost is low.
