Abstract
The utility model discloses a solid forging hydrogenation gate valve is taken over to valve body, including valve body and takeover, the valve body becomes a whole that has the cavity with the takeover through die -casting, installs the throttling arrangement of control pipeline circulation in the vertical direction of valve body and takeover junction, and the takeover is passed through the cavity and form the route, throttling arrangement can reciprocate in the cavity of valve body and takeover. Throttling arrangement includes flashboard and disk seat, and the motion of disk seat groove can be followed to the flashboard in the disk seat. Throttling arrangement still includes valve rod, valve -stem nut and hand wheel, and the hand wheel center is equipped with the screw suit on the valve rod top, and it is fixed that valve rod top and hand wheel pass through valve -stem nut, valve rod bottom and valve plate fixed connection. The utility model discloses the technical problem who solves is, the structure of taking over solid forging through the valve body is avoided appearing the welding seam and is pressed from both sides defects such as sediment, gas pocket, removes X -ray radiographic inspection detection procedures from, improves the valve quality, reduction in production cost.
Description
Technical field
This utility model relates to valve body pipe fitting technical field, particularly relates to a kind of valve body adapter solid forging hydrogenation gate valve.
Background technology
Gate valve is widely used on the pipelines such as petrochemical industry, serves the effect controlling pipeline internal medium circulation and closing, and it has
Flow resistance is little, keying is flexible, life-span length, compact conformation, the feature such as safe and reliable.Common welding ends forged steel gate valve size is less,
Corresponding distance from welding ends to sealing pair is shorter, and the heat produced when valve is with pipeline welding can affect the sealing of sealing surface
Performance.For existing band adapter forged steel gate valve, valve body is connected by welding manner with adapter.Valve body needs with the welding ends of adapter
Processing bevel for welding, needs butt welded seam to carry out radiographic inspection after welding.The forging gate valve of normal tape adapter is by valve body, adapter combination
Being welded, easily there is slag inclusion, pore in weld seam, causes leaking outside of valve, and heat during welding can affect the sealing of sealing surface
Energy.Separately eliminating bad due to post-weld stress, be easily generated deformation, impact seals.The technical problems to be solved in the utility model is,
Avoid the occurrence of the defects such as weld seam slag inclusion, pore by the structure of valve body adapter solid forging, remove radiographic inspection detecting step from, carry
High valve mass, reduces production cost.
Utility model content
This utility model, for overcoming the deficiencies in the prior art, uses the structure of valve body adapter solid forging thus avoids the occurrence of weld seam folder
The defect such as slag, pore, removes radiographic inspection detecting step from, improves valve mass, reduces production cost.
This utility model is achieved through the following technical solutions: a kind of valve body adapter solid forging hydrogenation gate valve, it is characterised in that bag
Including valve body, adapter, flashboard, valve seat, described valve body becomes an entirety with chamber, valve body and adapter with adapter by die casting
Being provided with the throttling arrangement controlling pipeline flow in the vertical direction of junction, adapter is by described chamber and forms path, institute
Stating valve seat to be arranged in described adapter, described flashboard can move along valve seat groove in valve seat.
Wherein, use for convenience, described valve body adapter solid forging hydrogenation gate valve, also include valve rod, valve stem nut and hands
Wheel, described valve rod is arranged in described valve body, and the center of described handwheel is provided with screw and is sleeved on described valve stem tip, described valve rod
Top is fixed by described valve stem nut with described handwheel, and described valve rod bottom is fixing with described flashboard to be connected.
Wherein, in order to ensure the stability that valve seat is connected with valve body, described valve seat passes through taper pole head and the valve body of its end
Fix in the way of extruding.
This utility model has the advantage that the weld seam not existed between valve body and adapter compared to existing technology, it is entirely avoided because of weldering
The product quality problem that seam defect causes, as slag inclusion, pore, the deformation etc. that post-weld stress inequality causes occurs in weld seam；Need not
Bevel for welding on processing valve body and adapter, eliminates machining and welding sequence.
Accompanying drawing explanation
Fig. 1 is that valve body adapter solid forging is hydrogenated with gate valve schematic diagram；
Fig. 2 is valve inner valve seat and joint structure connecting valve schematic diagram；
Fig. 3 is valve seat spreading pre-structure schematic diagram；

Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment enters under premised on technical solutions of the utility model
Row is implemented, and gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following
Embodiment.
Embodiment 1
As it is shown in figure 1, a kind of valve body adapter solid forging is hydrogenated with gate valve, including valve body 1, adapter 2, flashboard 3, valve seat 4,
Valve rod 5, valve stem nut 6, handwheel 7, screw 8.
In embodiment 1 valve body adapter solid forging hydrogenation gate valve, it is characterised in that include valve body 1, adapter 2, flashboard 3,
Valve seat 4, described valve body 1 becomes an entirety with chamber with adapter 2 by die casting, and valve body 1 hangs down with adapter 2 junction
Nogata is upwards provided with the throttling arrangement controlling pipeline flow, and adapter 2 is by described chamber and forms path, described valve seat 4
Being arranged in described adapter 2, described flashboard 3 can move along valve seat groove in valve seat 4；With prior art is compared, the present embodiment
In valve body adapter solid forging hydrogenation gate valve, do not exist valve body and adapter between weld seam, it is entirely avoided because weld defect causes
Product quality problem, as slag inclusion, pore, the deformation etc. that post-weld stress inequality causes occurs in weld seam；Need not process valve body and
Bevel for welding in adapter, eliminates machining and welding sequence.
Meanwhile, can be vertically fixed in adapter 2 to save material and valve body easy to use 1.Described valve body adapter entirety
Forging hydrogenation gate valve, also includes that valve rod 5, valve stem nut 6 and handwheel 7, described valve rod 5 are arranged in described valve body 1, institute
State the center of handwheel 7 to be provided with screw 8 and be sleeved on described valve rod 5 top, described valve rod 5 top and described handwheel 7 by described
Valve stem nut 6 is fixed, and described valve rod 5 bottom is fixing with described flashboard 3 to be connected.In order to actual working environment needs, adapter 2
Length can be controlled length according to actual needs.
Valve seat 4 is connected on valve body 1 by the form of one end spreading as in Figure 2-4.The valve seat 4 taper circle by its end
Club head fixes in the way of extruding with valve body 1.After valve seat 4 is arranged on valve body 1, it is the pole of taper by end,
One end of spreading valve seat 4 under the effect of forcing press, makes valve seat 4 spreading be partially embedded on the corresponding conical surface of valve body 1, plays solid
