Description
Technical field:
The utility model relates to oil field long-distance transport pipes technical field, in particular to a kind of ball valve for long-distance pipeline.
Background technique:
Long distance oil-gas conveyance conduit is known as long-distance transport pipes, and ball valve for long-distance pipeline is used for pipeline emergency cut-off, long defeated pipe
Thread ball valve has the characteristics that volume is big, weight is big.Ball valve body currently used for long-distance transport pipes mostly uses welding procedure to manufacture greatly.
As all-welded ball valve valve design manufacturing technology is perfect by continuing to develop, ball is mainly had according to the Shape Classification of valve body at present
Body formula, barrel-type, short cartridge type etc.；However in actual use, dirt can be generated because of being used for a long time inside ball valve, generated dirty
Ball valve after dirt does not have the effect shut off to pipeline, when happening suddenly emergency, cannot effectively cut off pipe-line, because
This can cause accident；Therefore in actual use, staff must periodically clear up ball valve, most of ball in the market
Valve is in spherical, therefore taking-up is more troublesome, is not easy to clear up.
Utility model content:
The technical problem to be solved by the present invention is to provide a kind of ball valve for long-distance pipeline, and the arrangement achieves valve body taking-ups
It is convenient, it is convenient to clean and safeguards, structure is simple, and sealing effect is good, and it is safe and reliable, reduce the danger occurred by valve body blocking
Danger.It overcomes existing ball valve body of long and takes out trouble, it has not been convenient to clear up, use unsafe deficiency.
Technical solution adopted in the utility model is: a kind of ball valve for long-distance pipeline, including cylinder；Cylinder upper end opening,
And cover is bolted in the opening, cylinder left and right ends are designed with connecting tube, and design has bullet on cylinder inner surface
Property rubber layer, columnar valve body is installed in cylinder, is sealed between valve body and cylinder by India rubber layer, the connection of valve body upper end
Bull stick, bull stick upper end pass through cover and are connected with rotating handle, be rotatablely connected between bull stick and cover, cylinder can be connected to by being provided on valve body
The through-hole of left and right ends connecting tube, rotary valve can be such that ball valve for long-distance pipeline closes.
Non-slip groove corresponding with bolt is provided on cylinder, non-slip groove is in a ring.
Valve body bottom end is arc-shaped, and cylinder bottom inner surface and valve body bottom end are adapted.
Design has chamfering on the inner wall of cylinder upper end.
It is connected between bull stick and cover by tapered roller bearing.
It is an integral molding structure between cylinder and connecting tube.
The beneficial effects of the utility model are: to realize valve body convenient to remove for the utility model, it is convenient to clean and safeguards, tie
Structure is simple, and sealing effect is good, safe and reliable, reduces the danger occurred by valve body blocking.
Detailed description of the invention:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the appearance schematic diagram of the utility model.
Specific embodiment:
As shown in Figure 1 and Figure 2, a kind of ball valve for long-distance pipeline, including cylinder 1；1 upper end opening of cylinder, and it is logical in the opening
It crosses bolt 4 and connects cover 3,1 left and right ends of cylinder are designed with connecting tube 2, flexible rubber layer 7 are designed on 1 inner surface of cylinder,
Columnar valve body 5 is installed in cylinder 1, is sealed between valve body 5 and cylinder 1 by India rubber layer 7, the connection of 5 upper end of valve body turns
Bar 8,8 upper end of bull stick pass through cover 3 and are connected with rotating handle 9, be rotatablely connected between bull stick 8 and cover 3, being provided on valve body 5 can connect
The through-hole 6 of logical 1 left and right ends connecting tube 2 of cylinder, rotary valve 5 can be such that ball valve for long-distance pipeline closes.
Non-slip groove 10 corresponding with bolt 4 is provided on cylinder 1, non-slip groove 10 in a ring, prevents bolt 4 from slipping.
5 bottom end of valve body is arc-shaped, and 1 bottom inner surface of cylinder and 5 bottom end of valve body are adapted, and increase base contact surface
Product, sealing effect is more preferable, meanwhile, the lower end of valve body 5 is not easy to scratch India rubber layer 7.
Design has chamfering on 1 upper end inner wall of cylinder, convenient for the insertion of valve body 5.It was between valve body 5 and India rubber layer 7
Therefore cooperation of being full of facilitates insertion equipped with chamfering.
It is connected between bull stick 8 and cover 3 by tapered roller bearing, is convenient for axially loaded.
It is an integral molding structure between cylinder 1 and connecting tube 2, convenient for manufacture, also more solid, connecting tube 2 is far from cylinder 1
One end and pipeline are tightly connected.
In use, valve body 5 is inserted into cylinder 1, fluid is pierced by through connecting tube 2, then via through holes 6, rotates rotating handle 9, bull stick 8
Band moving valve 5 rotates, and perpendicular shape, i.e. closed state between through-hole 6 and connecting tube 2 pass through between valve body 5 and cylinder 1 here
India rubber layer 7 seals, and seal length is long, and sealing effect is good, when needing to safeguard, unscrews bolt 4, removes cover 3, can be together with
Valve body 5 is extracted together, is cleared up, and valve body 5 is column, and taking-up is simple and convenient, is brought conveniently, is also reduced because of valve to maintenance
The danger that the blocking of body 5 occurs.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
