Description
Technical field
The utility model is related to a kind of oil-gas pipeline flat gate valve, belong to the manufacturing technology field of flat gate valve.
Background technology
On oil-gas pipeline, the main function of flat gate valve is the break-in operation for pipeline, after long-term work, in valve
There is repair or the demand replaced in part.It is to disassemble valve from pipeline to carry out maintenance under normal conditions, after finishing again
Valve is mounted on pipeline, this maintenance program is more convenient for the valve of flanged joint and easy-disassembling-assembling place.But
It often has that installation space is narrow or the valve of welding ends connection, to meet the needs of flat gate valve on-line maintenance, usually considers
Body cavity size is increased, provides enough spaces to use on-line maintenance instrument.But this mode necessarily greatly increases
Add the weight of valve and the appearance and size of valve.
For using no deflector hole flat gate valve, since flashboard does not have deflector hole, flashboard is shorter, in valve wide open state,
Valve seat support ring causes valve seat support ring V-shape state occur under the action of pretightning force because lacking support.It, can not when closing valve
There is the phenomenon that flashboard inordinate wear valve seat with avoiding, valve shelf life is caused to shorten.It can consider to increase valve under normal conditions
Internal chamber size provides enough spaces to install the supporting block of valve seat support ring.But this mode necessarily greatly increases
Add the weight of valve and the appearance and size of valve.
Utility model content
Technical problem to be solved in the utility model is：A kind of oil-gas pipeline Flat Sluice for facilitating on-line maintenance is provided
Valve.
Technical solution is used by the utility model to solve above-mentioned technical problem：Oil-gas pipeline flat gate valve, bag
Valve body is included, valve body both ends have the runner of coaxial arrangement, and runner is horizontally disposed with, and have vertically arranged cylinder in the middle part of valve body
Valve body middle chamber, the axis of valve body middle chamber pass through runner center；Cylindrical body cavity, body cavity and stream are equipped in the middle part of runner
Road is coaxially disposed and center overlaps, and body cavity diameter is more than flow diameter.
It is further:In valve body middle chamber and the connecting portion of body cavity, valve body has spherical shape.
It is further:Valve body is equipped with valve seat support ring, and valve seat support ring surrounding has spaced more than one piece /V
Plate.
It is further:Limiting plate is two pieces, is symmetricly set on valve seat support ring both sides.
The beneficial effects of the utility model are：Cylindrical valve body middle chamber can ensure that required empty when valve normally assembles
Between；Cylindrical body cavity can provide enough intracavity spaces, to place the support of online maintenance tool or valve seat support ring.
The utility model is with economic and practical valve body structure instead of previous manufacturing process of a high price, it is ensured that valve cavity has enough
Space realize on-line maintenance function.In addition, using spherical shape, it is ensured that valve good appearance；Valve seat support ring is provided with
Limiting plate forms valve seat support ring in the support of horizontal level, makes product quality more secure.

Specific embodiment
For ease of understanding with implementation the utility model, the preferred embodiment combination attached drawing work of anthology utility model is furtherly
It is bright.
As shown in Figure 1 and Figure 2, the utility model includes valve body 4, and valve body both ends have the runner 8 of coaxial arrangement, 8 water of runner
Flat to set, 4 middle part of valve body has vertically arranged cylindrical valve body middle chamber 9, and the axis of valve body middle chamber 9 passes through 8 center of runner；
8 middle part of runner is equipped with cylindrical body cavity 10, and body cavity 10 is coaxially disposed with runner 8 and center overlaps, in valve body
10 diameter of chamber is more than 8 diameter of runner.Wherein, design valve body middle chamber 9 internal diameter Φ D when, it should be ensured that when valve normally assembles must
Need space；When designing the radius R of body cavity 10, enough intracavity spaces need to be provided, to place online maintenance tool or valve seat
The support of bracing ring.
So that structure is more attractive, in valve body middle chamber 9 and the connecting portion of body cavity 10, valve body 4 has spherical shape.It needs
Spherical radius SR is determined in the case where ensureing valve body requirement wall thickness.
As shown in figure 3, valve body 4 is equipped with valve seat support ring 6,6 surrounding of valve seat support ring is limited with spaced more than one piece
Position plate 7.In the present embodiment, limiting plate 7 is preferably two pieces, is symmetricly set on 6 both sides of valve seat support ring.
The utility model dismantles the embodiment of valve internals：
As shown in figure 4, hydraulic pressure on-line maintenance instrument 2 is put between the valve seat support ring 6 in valve chamber, pass through hydraulic pump 1
Supercharging promotes the piston of hydraulic pressure on-line maintenance instrument 2 to be contacted with the limiting plate 7 in valve seat support ring 6, and pushes certain distance open,
Flashboard 3 is made to be disengaged with valve seat, so as to remove flashboard 3, then 1 pressure release of hydraulic pump, piston is withdrawn, and it is online to remove hydraulic pressure respectively
Maintenance tool 2 and valve seat support ring 6 achieve the purpose that dismantle valve internals.
The utility model replaces the embodiment of valve internals online：
As shown in figure 4, being successively packed into valve seat support ring 6, and locality is adjusted, then using hydraulic pressure on-line maintenance instrument
2 contact with the limiting plate 7 in valve body 4, valve seat support ring 6, and hydraulic pump 1 is pressurized, and valve seat support ring 6 are promoted to enter valve body 4, similarly
It is packed into second valve seat support ring 6.The contact surface of hydraulic pressure on-line maintenance instrument 2 is adjusted as the limiting plate 7 in valve seat support ring 6,
Hydraulic pump 1 is pressurized, and pushes valve seat support ring 6 open, is put into flashboard 3, and hydraulic pressure on-line maintenance instrument 2 is taken out in last 1 pressure release of hydraulic pump,
Achieve the purpose that replace valve internals online.
The embodiment of the utility model valve seat support ring assembling：
As shown in Figures 5 to 7, mode assembles valve seat support ring 6 as illustrated, treats the runner of valve seat support ring 6
When center line is overlapped with 4 runner center line of valve body, valve seat support ring 6 is rotated by 90 °, then assembles the support of valve seat support ring 6
Part is used to support the limiting plate 7 in valve seat support ring 6.
