Abstract
The present invention proposes the manufacture craft of a kind of easy-to-mount gate valve of valve seat and its valve seat, including valve body, the flashboard that is located in valve body and the valve seat with flashboard fitted seal, it is characterised in that：The valve seat is with valve body in being detachably connected, and one end that the valve seat is connect with valve body is stepped, and the valve seat other end is adapted to sealing with flashboard, and the valve seat is identical as the surface accuracy of valve body junction.The manufacture craft of the valve seat includes the following steps：1）Blank is forged by mold；2）Blank is processed to the precision of needs by numerical control device；3）Finished product valve seat is installed to valve body by stamping equipment.
Description
Technical field
Present invention relates particularly to the manufacture crafts of a kind of easy-to-mount gate valve of valve seat and its valve seat.
Background technology
The opening and closing element of gate valve is flashboard, and the direction of motion and flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete
It closes, cannot make adjustments and throttle.Flashboard there are two sealing surface, two sealing surfaces of most common pattern slide valve formed wedge shape,
Key groove is different with valve parameter, usually 5 °.Gate valve is widely used in various producers, and gate valve is matched by flashboard with valve seat
It is sealed.The gate valve of existing gate valve includes valve body, the valve deck being connected with valve body, flashboard, the valve rod and and lock for controlling flashboard
The valve seat of plate fitted seal.Do not allow easy-maintaining after the sealing surface wear of valve seat and replace, is connected between valve seat and valve body
It is insecure.The complex manufacturing technology of existing valve seat, of high cost, precision is low.
Invention content
Based on the above issues, present invention aims at providing, one kind is at low cost, precision is high, valve seat can be easy to disassemble and ties up
The gate valve repaiied.
In view of the above problems, providing following technical solution：A kind of easy-to-mount gate valve of valve seat, including valve body, be located at
Flashboard in valve body and the valve seat with flashboard fitted seal, the valve seat are in be detachably connected with valve body, the valve seat and valve
One end of body connection is stepped, and the valve seat other end is adapted to sealing with flashboard.
The present invention is further arranged to, and the valve seat is identical as the surface accuracy of valve body junction.
The manufacture craft of the valve seat includes the following steps：
1) blank is forged or cast out by mold；
2) blank is processed to the precision of needs by numerical control device；
3) finished product valve seat is installed to valve body by stamping equipment.
Beneficial effects of the present invention：Compared to existing gate valve, the present invention is at low cost, precision is high, valve seat can be easy to disassemble
And repair.Valve seat, in being detachably connected, easy to disassemble can be repaired with valve body after valve base sealing surface wear.Valve seat detachably may be used
So that the gate valve of the relatively each bore of valve seat can be general.Valve seat is identical as the surface accuracy of valve body junction to enable to valve
Seat outer wall is tightly attached to valve interior wall, to realize better seal.The manufacture craft of valve seat is simple, at low cost, precision it is high with
And fitness is good.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Figure label meaning：1- valve bodies；2- flashboards；3- valve seats.
Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
3 easy-to-mount gate valve of a kind of valve seat as shown in Figure 1, including valve body 1, the flashboard 2 that is located in valve body 1 and with
The valve seat 3 of 2 fitted seal of flashboard, the valve seat 3 are in be detachably connected with valve body 1, one end that the valve seat 3 is connect with valve body 1
Stepped, 3 other end of the valve seat is adapted to sealing with flashboard 2.
In the present embodiment, the valve seat 3 is identical as the surface accuracy of 1 junction of valve body.
The manufacture craft of the valve seat 3 includes the following steps：
1) blank is forged or cast out by mold；
2) blank is processed to the precision of needs by numerical control device；
3) finished product valve seat 3 is installed to valve body 1 by stamping equipment.
The present invention is at low cost, precision is high, valve seat 3 can be easy to disassemble and repairs.Valve seat 3 is in be detachably connected with valve body 1,
It easy to disassemble can be repaired after 3 sealing surface wear of valve seat.Valve seat 3 can detachably make the lock of the relatively each bore of valve seat 3
Valve can be general.Valve seat 3 is identical as the surface accuracy of 1 junction of valve body to enable to 3 outer wall of valve seat to be tightly attached to 1 inner wall of valve body,
To realize better seal.The manufacture craft of valve seat 3 is simple, at low cost, precision is high and fitness is good.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, above-mentioned hypothesis these
Improvement and modification also should be regarded as protection scope of the present invention.
