Description
Technical field
It is to be related to a kind of Novel-parallel gate valve specifically the present invention relates to a kind of gate valve.
Background technology
Valve be in fluid system, for control the direction of fluid, pressure, flow device be to make in pipe arrangement and equipment
Medium (liquid, gas, powder) flowing or stop and the device of its flow can be controlled, and gate valve is exactly one kind therein.Lock
The opening and closing element of valve (gate valve) is flashboard, and the direction of motion and flow direction of flashboard are perpendicular, gate valve can only make standard-sized sheet and
Fully closed, therefore, the medium for being mainly used in blocking or connecting in pipeline is typically used not as regulation or throttling.
But traditional gate valve, due to the design defect in its structure, the poor sealing performance of whole gate valve；In addition, flashboard and valve
The contact surface of seat easily weares and teares, and reduces service life；And do not reach seal request after being used for a long time at all, repair also very
It is inconvenience.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of good seal performance, service life length it is new
Type Parallel gate valve Parallel slide valve.
To reach above-mentioned purpose, technical scheme is as follows：A kind of Novel-parallel gate valve, including valve body, valve rod,
Valve seat, flashboard and drive device, the valve seat and flashboard may be contained within the valve inner；One end of the valve rod is located at institute
Valve inner is stated, and connects the flashboard, its other end stretches out in the valve body, and connection drive device；The drive device
Driving the valve rod to move up and down finally makes the keying of the flashboard and the valve seat；The flashboard be parallel to each other including two pieces and
Independent circular flashboard, the circular flashboard is located at the both sides of valve stem end respectively, and is connected respectively with valve rod flexible fastening.
Further, the Novel-parallel gate valve also includes the bonnet for being arranged at the valve inner sealing part, described
Valve rod, which is arranged between the inside of the bonnet, and the valve rod and bonnet, is provided with multi-layer sealed filler.
Further, bushing and gland are had additional successively above the airtight and watertight padding.
Further, the airtight and watertight padding is graphite.
Further, the sealing surface of the valve seat is in that the wide micro- angle of type is set.
Further, the bonnet is fixedly connected by Dual positioning with the valve body, and the Dual positioning includes first
Keeper and the second keeper.
Further, engagement contact sealing is set between the flashboard and valve seat.
Further, the sealing surface of the flashboard be set to it is continuous concavo-convex, the sealing surface of the valve seat be set to
Its continuous convex-concave shape matched.
Further, the Novel-parallel gate valve also includes the support arm for being used to support the valve rod.
Further, the switch for opening and closing the valve body is provided between the valve rod and support arm.
Using above-mentioned technical proposal, the beneficial effect of technical solution of the present invention is：Drive device driving valve rod is moved downward,
It is slowly descending so as to drive flashboard to be synchronized with the movement indirectly, until two pieces of circular flashboards are each mutually sealed with valve seat, realize dual
Sealing function, improves the sealing property of whole gate valve, meanwhile, the contact surface between flashboard and valve seat is added, mill is reduced
The loss brought is damaged, service life is extended.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiment 1
As shown in Figure 1-2, a kind of Novel-parallel gate valve, including valve body 1, valve rod 2, valve seat 3, flashboard 4 and driving dress
Put, valve seat 3 and flashboard 4 may be contained within inside valve body 1；One end of valve rod 2 is located inside valve body 1, and connection flashboard 4, and its is another
End stretches out in valve body 1, and connection drive device；Drive device driving valve rod 2 moves up and down and final makes opening for flashboard 4 and valve seat 3
Close；Flashboard 4 is parallel to each other and independent circular flashboard including two pieces, and circular flashboard is located at the both sides of the end of valve rod 2 respectively, and divides
It is not connected with the flexible fastening of valve rod 2；Drive device device in the present embodiment is handwheel.
Novel-parallel gate valve also includes being arranged at the bonnet 5 at the inner seal of valve body 1, and valve rod 2 is arranged in the interior of bonnet 5
Multi-layer sealed filler 6 is provided between portion, and valve rod 2 and bonnet 5.The top of airtight and watertight padding 6 has additional bushing 7 and filler pressure successively
Lid 8, improves whole tightness.Wherein, airtight and watertight padding 7 is graphite.
Novel-parallel gate valve also includes the support arm 9 for being used to support valve rod 2, and being provided between valve rod 2 and support arm 9 is used for
Open and close the switch 10 of valve body 1.
The operation principle of the present embodiment is described below：Gate valve is opened, first switch 10 is opened, makes 9 points of valve rod 2 and support arm
Open, handwheel is rotated afterwards so that valve rod 2 is moved upwards, drive connecting rod 13 to move upwards indirectly, now flashboard 4 follows connection
Bar 13 is synchronized with the movement, until flashboard 4 is kept completely separate with valve seat 3, completes the unlatching work of gate valve；Closing gate valve, according to opposite
Direction rotate handwheel so that valve rod is moved downward, flashboard 4 is synchronized with the movement downwardly together therewith, slowly close with valve seat 3
Contact, until flashboard 4 moves to bottom, realizes complete closed with valve seat 3, the Operating In Persistent Current Mode of completion gate valve, finally will switch
10 lock.
Embodiment 2
Remaining is same as the previously described embodiments, and difference is, the sealing surface of valve seat 3 is in that the wide micro- angle of type is set, Neng Gouyou
