Abstract
The utility model relates to a novel ball valve. The existing ball valve not only has high precision in matching and machining, and higher machining cost, but also can reduce the sealing effect greatly, even can leak water if a valve seat or a valve core is deformed. The novel ball valve mainly comprises a valve body, a ball core, a valve hood, a screw rod and a pressing hood, wherein the ball core is arranged in the valve body in a matching way, the valve hood is in threaded connection and fixed with the valve body, the screw rod is connected with the valve body in an inserting way and is connected with the ball core in a clamping way, the pressing hood is sheathed with the screw rod and is in threaded connection with the valve body, a sealing ring I is arranged between the ball core and the valve body, a sealing ring II is further arranged between the sealing ring I and the ball core, an annular groove is arranged on the sealing ring II, the sealing ring I is arranged in the groove, and the sealing ring II is in sealing fit with the ball core as well as the valve body. The novel ball valve is simple and reasonable in structure; the sealing ring II is made of Polytef, so that the corrosion resistance and the lubricity are high; and when the ball valve is rotated by the screw rod, the resistance is low, and the operation is easy. In the novel ball valve, the sealing effect is enhanced as double seals, namely, the sealing ring I and the sealing ring II, are adopted.
Description
Technical field
The utility model relates to a kind of ball valve, refers in particular to a kind of ball valve.
Background technique
Open-shut device (spheroid) is driven by valve rod, and the valve that rotates around the axis of valve rod.Be mainly used in the medium that blocks or connect in the pipeline, also can be used for the adjusting and the control of fluid, wherein seal firmly between the metal seat valve of its V-type ball core of V-type ball valve and pile-up welding hard alloy and have very strong shearing force, be specially adapted to media such as fibre-bearing, small solid particle.And the multi-pass ball valve not only interflow of control media, shunting, and switching of flowing to flexibly on pipeline also can be closed arbitrary passage simultaneously and two other passage is linked to each other.
Therefore there is the people to design " ball valve " by name (China Patent No. 99102601.2, notice of authorization CN1225431A), it mainly is made of valve body, spool, valve seat, last valve shaft and lower valve shaft, this patent is being provided with deformation ditch and following deformation ditch on the spool, major axis footpath axial plane by the oval pillow block on the lower valve shaft is to the effect of the deformation effect power active force that ditch revolves on the spool, the deformation ditch is produced open deformation, last deformation ditch produces and closes up deformation, thereby reaches sealing.Above-mentioned spool adopts with valve seat and firmly hard rigidity is contacted, though can reach seal action,, cooperating and the machining accuracy height between its spool and the valve seat, processing cost is higher, simultaneously, if when valve seat or spool produce distortion, its sealing effect will be had a greatly reduced quality, even occur leaking.
Simultaneously; the somebody designs " ball valve " by name (China Patent No. 200610026327.1, notice of authorization CN 101067456A); it mainly is made up of valve body, ball core, valve rod and handle; this patent mainly is provided with anticorrosion through hole on the ball core; make the same with pipeline abrim always medium in the ball valve body cavity; with the formation protective film, thus the working life of prolongation ball valve.But above-mentioned patent only considers that protection ball core is not corroded, and has ignored the seal ring that is arranged on ball core both sides, and under the corrosion of corrosivity liquid, it is aging that seal ring very easily is corroded, thereby reduced sealing effect, even occur leaking.
The model utility content
The purpose of this utility model is at existing in prior technology the problems referred to above, and it is a kind of simple and reasonable for structure that the spy provides, and the ball valve of favorable sealing property.
For solving the problems of the technologies described above, this ball valve, mainly form by valve body, ball core, bonnet, screw mandrel and pressure cap, its ball core is equipped with in valve body, bonnet and valve body are spirally connected fixing, its screw mandrel and valve body peg graft and with the clamping of ball core, pressure cap and screw mandrel socket also are spirally connected with valve body, be provided with seal ring I between its ball core and the valve body, wherein, also be provided with seal ring II between above-mentioned seal ring I and the ball core, sealing circle II is provided with annular groove, above-mentioned seal ring I is located in this groove, and its seal ring II cooperates with ball core and valve seal.Above-mentioned seal ring I is an O type circle.Above-mentioned seal ring II is a plastics king seal ring.
The beneficial effects of the utility model are: simple and reasonable for structure, its seal ring II adopts teflon to make, it is insoluble to strong acid, highly basic and organic solvent, and corrosion that can the powerful oxidation corrosion resistance agent, has corrosion resistance preferably, still can keep ductility at high temperature or low temperature environment, anti-aging, and have high-lubricity, when rotating ball valve by screw mandrel, resistance is little, and operation easily.Simultaneously, the utility model adopts seal ring I and seal ring II double seal, strengthens its sealing effect.
