Description
Technical field
The present invention relates to valve technology field, especially a kind of high performance steel gate valve.
Background technique
Gate valve is an opening and closing element flashboard, and the direction of motion of flashboard is vertical with flow direction, and flashboard can only make standard-sized sheet and complete
Close, be not suitable for door parameter and it is different, most of gate valve use forced seal, i.e., valve close when, by external force by force by
Flashboard presses to valve seat, to guarantee the leakproofness of sealing surface.The flashboard of gate valve is for linear motion with valve rod, is lifting lever brake
Valve is also Outside screw stem rising through handwheel type gate valve.Some valve rod nut for gate valve are located on flashboard, and hand wheel rotating band ovable valve stem rotates, and promotes flashboard,
This valve is called swingle gate valve or is inside screw nonrising stem type gate valve.Gate valve is typically all that flashboard does relative motion with valve seat, and flashboard with
Valve seat requires sealing to require relative motion again, and long-time flashboard and valve seat will mutually be worn, and influences the sealing performance of gate valve,
It is relatively short in particular for the gate valve service life being often opened and closed.
Summary of the invention
For above situation, for the defect for overcoming the prior art, the purpose of the present invention is just to provide a kind of high performance steel
Check valve improves the leakproofness of flashboard and valve seat, long service life.
Its solution is a kind of high performance steel gate valve, the valve body including having left and right channel, and the inside of valve body is embedding
Entering has valve seat, and valve body top is equipped with valve deck, and the lower part of the valve body is equipped with flashboard slot, and valve body top, which is equipped with, enters slot, flashboard
The two sidewalls of slot are equipped with mounting groove, rotation section are rotatably connected in the mounting groove, rotation section is fixed with sealing ring, described close
Seal ring top is equipped with the driving section protruded into slot, and the lock of the interstitial hole for close encapsulation ring is equipped between two sealing rings
Plate, the top of flashboard are equipped with fixed block, and fixed block is rotatably connected to valve rod, and valve rod stretches out valve deck and opposite with valve deck close upwards
Envelope, valve deck top are fixed with support frame, and valve rod stretches out valve deck end and is equipped with threaded portion, are fixed with nut on support frame, threaded portion with
Nut thread connection, the lower end of fixed block are equipped with sealing-plug, and sealing-plug is located at the outside of driving section, and sealing-plug is for sealing transmission
Gap between portion and valve seat and between fixed block and valve seat, when flashboard is located at lowest part, the lower end of flashboard reaches flashboard
Slot is sealed with flashboard slot and two sealing rings are contacted with ram seal.
Preferably, sealing ring is equipped with sealant close to the side of flashboard.
Preferably, it is equipped with into the inner wall of slot and fills in the auxiliary tank into slot convenient for sealing-plug.
Preferably, not in same plane, rotation section is tilted to the direction away from flashboard downwards, described for rotation section and sealing ring
Not in same plane, driving section is tilted to the direction away from flashboard upwards for driving section and sealing ring.
Preferably, the both ends of valve body are equipped with flange arrangement.
Beneficial effects of the present invention: since the stroke that sealing ring and flashboard generate larger frictional force is shorter, flashboard and sealing
Ring wears small, raising sealing performance and service life when being opened and closed；Valve body and the embedded assembly of valve seat, rotation section and valve body rotation connect
It connects, can be realized disassembly, sealing ring can be replaced after seal wears, the gate valve is enabled to repair reuse, extension makes
With the service life, use cost is reduced.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the schematic diagram of sealing ring of the present invention.
Specific embodiment
Below in conjunction with attached drawing, specific embodiments of the present invention will be described in further detail.
Provided by Fig. 1 and Fig. 2, a kind of high performance steel gate valve, including have left and right channel valve body 1, valve body 1 it is interior
Portion is embedded with valve seat 2, and 1 top of valve body is equipped with valve deck 3, which is characterized in that the lower part of the valve body 1 is equipped with flashboard slot 4, valve body
1 top, which is equipped with, enters slot, and the two sidewalls of flashboard slot 4 are equipped with mounting groove 5, are rotatably connected to rotation section 6 in the mounting groove 5,
Rotation section 6 is fixed with sealing ring 7, and 7 top of sealing ring, which is equipped with, to be protruded into the driving section of slot 8, between two sealing rings 7
The top of flashboard 9 equipped with the interstitial hole for close encapsulation ring 7, flashboard 9 is equipped with fixed block 10, and fixed block 10 is rotatably connected to
Valve rod 11, valve rod 11 stretch out upwards valve deck 3 and with 3 opposing seal of valve deck, 3 top of valve deck is fixed with support frame 12, and valve rod 11 is stretched
3 end of valve deck is equipped with threaded portion out, is fixed with nut 13 on support frame 12, threaded portion is threadedly coupled with nut 13, fixed block 10
Lower end is equipped with sealing-plug 14, and sealing-plug 14 is located at the outside of driving section 8, and sealing-plug 14 is for sealing between driving section 8 and valve seat 2
And the gap between fixed block 10 and valve seat 2, when flashboard 9 is located at lowest part, the lower end of flashboard 9 reaches flashboard slot 4 and lock
Board slot 4 seals and two sealing rings 7 are in sealing contact with flashboard 9.
The sealing ring 7 is equipped with sealant close to the side of flashboard 9.
The inner wall into slot, which is equipped with, fills in the auxiliary tank 15 into slot convenient for sealing-plug 14.
The rotation section 6 is not with sealing ring 7 in same plane, and rotation section 6 is tilted to the direction away from flashboard 9 downwards, institute
Driving section 8 and sealing ring 7 are stated not in same plane, driving section 8 is tilted to the direction away from flashboard 9 upwards.
The both ends of the valve body 1 are equipped with flange arrangement 16.
The present invention, rotation valve rod 11, due to the threaded portion of valve rod 11 and the effect of nut 13, valve rod 11 can drive flashboard
9 move up and down.During flashboard 9 moves downward closure, since sealing-plug 14 is not entered into slot, sealing ring 7 can
With rotation, flashboard 9 is moved downward, and active force very little when not contacting or contact between sealing ring 7, flashboard 9 continues to transport downwards
Dynamic, sealing-plug 14 is entered into slot, and sealing-plug 14 is pressing against driving section 8, so that sealing ring 7 is rotated to 9 direction of flashboard, flashboard
9 enter flashboard slot 4 and the sealing of flashboard 9, and sealing-plug 14 squeezes driving section 8 but also sealing between sealing ring 7 and flashboard 9, together
When sealing-plug 14 again between sealed valve body 1, driving section 8, fixed block 10 gap, and then realize gate valve sealing.
Beneficial effects of the present invention: since the stroke that sealing ring and flashboard generate larger frictional force is shorter, flashboard and sealing
Ring wears small, raising sealing performance and service life when being opened and closed；Valve body and the embedded assembly of valve seat, rotation section and valve body rotation connect
It connects, can be realized disassembly, sealing ring can be replaced after seal wears, the gate valve is enabled to repair reuse, extension makes
With the service life, use cost is reduced.
Embodiment described above is not intended to limit the scope of the present invention, before not departing from design concept of the present invention
It puts, the various changes and improvements that those skilled in the art make technical solution of the present invention should all be included in the present invention
Claims determine protection scope in.
