At present, welding gate valve is widely used on oil and natural gas pipeline, be arranged on oil recovery, oil refining, Coal Chemical Industry, petrochemical industry, chemical industry, chemical fibre, metallurgy, electric power, nuclear power, etc. under high temperature medium apparatus.Due to the cylindrical structure that existing welding gate valve is overall, when needing to repair when welding brake gate door pipeline breaks down, welding brake gate door must be disassembled from pipeline, just can place under repair to spool, flashboard and valve seat, so not only repair procedures is loaded down with trivial details, and due to the repairing time long, make the loss in production be difficult to reduce.
Therefore, the valve core structure designing a kind of upper dress formula welding plate gate valve can repaired on pipeline is needed.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of valve core structure of the upper dress formula welding plate gate valve can repaired on pipeline.
In order to achieve the above object, the utility model devises a kind of valve core structure of upper dress formula welding plate gate valve, comprise valve seat carrier, it is characterized in that: spool comprises valve seat carrier and chock, breach is provided with between two panels valve seat carrier, chock inserts in breach, and described valve seat carrier is semi-cylindrical, and described chock is the cone structure of left and right symmetry.
When upper dress formula welding plate gate valve normally works, spool is arranged on the inside of valve body.
When upper dress formula welding plate gate valve needs repairing, the bottom of spool is fixed on the top of valve body, and top and the valve gap of spool are fixed.
The channel circumference of described valve seat carrier is provided with seal groove.
Described seal groove is circular seal groove or quad seal groove.
The top of described valve seat carrier is provided with half tongue-and-groove, and the top of valve body is provided with second half tongue-and-groove, and half tongue-and-groove and second half tongue-and-groove are combined to form groove, and groove is connected with the convex surface of valve gap.
Pad is provided with between described groove and described valve gap.
Described valve seat carrier internal surface be provided with three road cross reinforcings with together with waling.
The cone angle of described chock is 3 °.
The top of described chock is provided with craft thread hole.
The cross section of described chock is circular arc.
The utility model compared with the existing technology, devises the valve core structure of dress formula welding plate gate valve, and when valve normally works, spool is arranged on the inside of valve body; When valve break down on pipeline need repair time, need only dismantle middle flange bolt and nut, take off valve gap together with valve rod group component from valve body, then takes out spool, ram assemblies, can repair flashboard and valve seat online.This maintenance not only saves the time, also achieves online repairing, thus the loss in producing is dropped to minimum point.

Embodiment
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 1 and Fig. 2, the utility model devises a kind of valve core structure of upper dress formula welding plate gate valve, comprises valve seat carrier.Spool 12 comprises valve seat carrier 2 and chock 3, and be provided with breach 6 between two panels valve seat carrier 2, chock 3 inserts in breach 6.
See Fig. 3 and Fig. 4, the channel circumference of valve seat carrier 2 is provided with seal groove.Seal groove is circular seal groove 4 or quad seal groove 5, ensure that the sealing between spool 12 and valve body 1.
Valve seat carrier 2 internal surface be provided with three road cross reinforcings 10 with together with waling 11, to ensure the intensity of valve seat carrier 2, and retain suitable space and be connected with valve seat and protective housing.
Valve seat carrier 2 is semi-cylindrical.
See Fig. 5 and Fig. 6, chock 3 is the cone structure of left and right symmetry, and the cone angle 13 of chock 3 is 3 °, and the top of chock 3 is provided with craft thread hole 13, so that dismounting.
The cross section of chock 3 is circular arc, mates with valve seat carrier 2.
In order to ensure the convenient disassembly of spool 12 and enough sealing intensities, two panels circular arc is adopted to carve son 3.In assembly process, two panels is carved son and 3 to be inserted in two half semi-cylindrical valve seat carriers 2, forms complete cylindrical spool 12 structure.By carving the active force that son 3 inserts, strut valve seat carrier 2, crush seal circle, to ensure the sealing between spool 12 and valve body 1.
