Abstract
The invention discloses a top entry floating ball valve capable of being maintained on line. The top entry floating ball valve capable of being maintained on line comprises a valve body, a valve deck matched with the valve body, a ball body, a valve rod, a locating screw, a belleville spring and a handle. The ball body is arranged in the valve body, the valve deck is arranged at the upper portion of the valve body and forms a containing cavity, and the ball body is sealed in the containing cavity. The valve rod penetrates from the top of the valve deck and is detachably connected with the ball body. Valve rod packing is arranged between the top end of the valve deck and the valve rod. The valve rod is provided with the belleville spring in a sleeved mode and the belleville spring presses the valve rod packing. The connection end of the handle is fixed to the top end of the valve rod in a sleeved mode through the locating screw. A thrust pad is arranged between the bottom of the ball body and the valve body in a cushioning mode and used for guaranteeing the stability in the opening and closing processes of the ball valve. According to the top entry floating ball valve capable of being maintained on line, on-line disassembly and assembly on a pipeline and fast replacement of damaged parts can be achieved.
Description
Technical field
The present invention relates to a kind of upper dress formula floating ball valve that can on-line maintenance.
Background technique
At present, upper dress formula floating ball valve is widely used on the pipeline of oil and natural gas, and the industry such as petrochemical industry, electric power, nuclear power and papermaking.Existing ball valve cannot realize valve in the time being out of order, online repairing, and upper dress floating ball valve only need be removed the screw of valve gap, just can take out spheroid and valve component, so just can change new parts and repairing damaged part, on-line maintenance has been saved the time, and the loss in producing is reduced to minimum.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of upper dress formula floating ball valve that can on-line maintenance, can realize online dismounting on pipeline and change rapidly the object of part of damage by this ball valve.
Technological scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
Upper dress formula floating ball valve that can on-line maintenance, the valve gap, spheroid, valve rod, the positioning screwn that comprise valve body, match with valve body, butterfly spring, handle; It is characterized in that: described spheroid is arranged on valve inner, described valve gap is arranged on valve body top and forms accommodating cavity by ball seal wherein; Valve rod through removably connecting with spheroid, arranges stem packing between described valve gap top and valve rod from valve gap top, and on valve rod, also sheathed butterfly spring is pressed in stem packing, and the connecting end of handle is by the sheathed valve stem tip that is fixed on of positioning screwn; Between described spheroid bottom and valve body, pad is provided with the stability of thrust pad when ensureing ball valve switch.
As preferred version, described upper dress formula floating ball valve that can on-line maintenance, is characterized in that: between described spheroid and valve body, symmetry has valve component, described valve component comprises successively interior clamp holder, seal ring, O type circle and the outer clamp holder of clamping mutually; Described valve gap below is provided with convex shoulder structure valve component is fixed.
Institute is as preferred version, state can on-line maintenance upper dress formula floating ball valve, it is characterized in that: described stem packing is Graphite pad.
As preferred version, described upper dress formula floating ball valve that can on-line maintenance, is characterized in that: described thrust pad upper and lower surface is plane structure.
As preferred version, described upper dress formula floating ball valve that can on-line maintenance, is characterized in that: also comprise that gland, described gland upper end are connected with the connecting end of handle, lower end is supported to valve gap upper surface.
Beneficial effect: upper dress formula floating ball valve that can on-line maintenance provided by the invention, 1, easy to maintenance, simple in structure, seal ring is all generally movable, dismounting and change is all more convenient.2, electrostatic-proof function: between spheroid, valve rod, valve body, spring is set, the static that switching process can be produced is derived.3, because the materials such as teflon have good self lubricity, little with the friction loss of spheroid, therefore the long service life of ball valve.4, fluid resistance is little: pneumatic ball valve is the one of fluid resistance minimum in all valve classification, even undergauge pneumatic ball valve, its fluid resistance is also quite little.5, valve stem seal is reliable: do not move up and down because valve rod only rotates, the packing seal of valve rod is survivable, and sealability increases along with the increased pressure of medium.6, valve base seal property is good: the seal ring that adopts teflon elastomeric material to make, structure is easy to sealing, and the jam pot cover ability of pneumatic ball valve increases along with increasing of pressure medium.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure: 1 valve body, 2 valve gaps, 3 spheroids, 4 valve rods, 5 outer clamp holders, 6 interior clamp holders, 7 seal rings, 8 O shape circles, 9 thrust pads, 10 stem packings, 11 glands, 12 positioning screwns, 13 butterfly springs, 14 handles.
