There is very strong shearing force between the metal seat valve of weldering hard alloy, Jie of fibre-bearing, small solid material etc. is particularly well-suited to
Matter.And multi-pass ball valve not only flexibly can control on pipeline the interflow of medium, shunting, and flow direction switching, while can also close
Arbitrary passage and make two other passage be connected.Ball valve should be typically horizontally mounted in the duct.Ball valve is according to type of drive point
For：Pneumatic ball valve, electrical ball valve, manual ball valve.
Union or articulation (union) are called by appointing, are a kind of conventional conduit coupling that can facilitate installing/dismounting.Ball valve
Have wide range of applications, need the product type with movable joint structure.
Utility model content
The purpose of this utility model is to provide corrosion-resistant pair of fool proof by a ball relief valve is appointed, and is easy to quick installation.
The purpose of this utility model will be realized by following technical measures：Valve seat is in triplet type, in the middle part of the valve seat upwards
Projection simultaneously opens axis hole, in the outer mounting knob of the boss, has the through hole being connected with each other at the two ends of valve seat horizontal direction respectively,
There is screw thread and the internal thread loose joint cap that spins respectively on the valve seat outer wall that the two through holes are located, dispose in the cavity of middle part in valve seat
Valve element, middle part horizontal direction valve opening hole in valve element, valve element profile are spherical in shape, at the top of valve element have jack, handle lower end with should
Between jack, valve rod is installed in connection；Meanwhile, the internal diameter of the less through hole in the through hole of two ends in valve seat horizontal direction
Identical with valve opening, the internal diameter of another larger through hole is identical with valve element external diameter, and spin in the opening's edge of the larger through hole peace
The outer silk top cap of dress, outer silk top cap inner face hold out against valve element.
Especially, the through hole at valve seat horizontal direction two ends is coaxial, and the valve pocket in valve seat is coaxial with the two through holes.
Especially, outer silk top cap outer end is fixedly connected a joint, the inner radially annular protrusion of the joint, and is lived by internal thread
Cap outer end concentric contraction opening is connect along clamping.
Especially, slotted in handle elevationally outward, be slidably installed buckle wherein, the corresponding valve seat outer wall in lower end of buckle
On have a draw-in groove, when buckle is in low spot, the draw-in groove is inserted in its lower end.
Advantage of the present utility model and effect：Ball valve buckle plays safeguard protection effect, preferably prevents valve core rotation, makes
Valve body possesses foolproof function, will not arbitrarily operate and meet with into ball valve closing or open, with good fluid handling properties and closing
Sealing property；90 ° of reciprocating rotatings, switch are rapid, and driving moment is little, for the medium for blocking, connecting, adjust in pipeline；Design
Novelty, moulding are unique, simple for structure compact attractive in appearance, have texture, and corrosion resistance is strong, easily installs, applied range, wear-resistant,
It is easily disassembled, easy maintenance.Due between described active joint and valve body for being detachably connected cooperations, so installation and maintenance with
It is when changing accessory, simple and convenient.
Description of the drawings
Fig. 1 is 1 structural representation of this utility model embodiment.
Fig. 2 is 1 appearance schematic diagram of this utility model embodiment.
Reference includes：Handle 1, valve rod 2, valve seat 3, valve element 4, internal thread loose joint cap 5, outer silk top cap 6, joint 7, buckle
