Description
Technical field
The present invention relates to gate valve field more particularly to a kind of soft sealing gate valves of bi-direction zero-leakage high life.
Background technique
Be the shortcomings that gate valve at present: valve volume is big, is not able to satisfy complicated operating condition, and the requirement for pipeline is larger, and
And easily deform, sealing effect decline, the service life is low, and inconvenient maintenance, higher cost.
Summary of the invention
There is provided that a kind of structure is simple, operation side it is an object of the invention to overcome the deficiencies in the prior art described above place
Just, the soft sealing gate valve of practical bi-direction zero-leakage high life.
The present invention realizes in the following way:
A kind of soft sealing gate valve of bi-direction zero-leakage high life, it is characterised in that: including valve body, valve plate, screw rod, valve deck,
The valve body is equipped with water inlet, water outlet, mounting hole, and the inlet and outlet communicate, and the mounting hole is set to valve body
Middle part, and communicated with the stream chamber that inlet and outlet are mutually formed；The valve deck is bolted to the mounting hole of valve body
On；The middle and upper part of the screw rod is connected with screw rod snap ring；The lower part of the screw rod is arranged in valve deck and valve body, and under screw rod
End is located in valve body, while screw rod snap ring is arranged on the upper end of valve deck, and the screw rod can be rotated relative to valve body, the valve plate
It is connected on mounting plate, the mounting plate is connected on the lower end of screw rod, and screw rod drives valve plate rotation, so that valve plate is to water inlet
The movement opened and closed is realized with the stream chamber that water outlet is mutually formed；The top of the screw rod is arranged with fixed lid, the fixation
Lid is connected with valve deck；Handwheel is connected at the top of the screw rod.
Junction between the valve body and valve deck is equipped with gasket.
Junction between the screw rod and fixed lid is equipped with O-ring seal.
The beneficial effects of the present invention are: structure is simple, easy to operate, and long service life, sealing performance are reliable.
Detailed description of the invention
Fig. 1 schematic structural view of the invention.
Specific embodiment
Now in conjunction with attached drawing, the specific embodiment of the invention is described in detail:
As shown in Figure 1, a kind of soft sealing gate valve of bi-direction zero-leakage high life, including valve body 1, valve plate 2, screw rod 3, valve deck
4, valve body 1 is equipped with water inlet 11, water outlet 12, mounting hole 13, and the water inlet 11 and water outlet 12 communicate, and mounting hole 13 is set
In the middle part of valve body 1, and the stream chamber formed with water inlet 11 and 12 phase of water outlet communicates；Valve deck 4 is bolted to valve body 1
Mounting hole 13 on；The middle and upper part of screw rod 3 is connected with screw rod snap ring 6；The lower part of screw rod 3 is arranged in valve deck 4 and valve body 1, and
The lower end of screw rod 3 is located in valve body 1, while screw rod snap ring 6 is arranged on the upper end of valve deck 4, and screw rod 3 can turn relative to valve body 1
Dynamic, valve plate 2 is connected on mounting plate 7, and mounting plate 7 is connected on the lower end of screw rod 3, and screw rod 3 drives valve plate 2 to rotate, so that valve
Plate 2 realizes the movement opened and closed with the stream chamber that water outlet 12 is mutually formed to water inlet 11；The top of screw rod 3 is arranged with fixation
Lid 8, fixed lid 8 are connected with valve deck 4；The top of screw rod 3 is connected with handwheel 9.
Junction between valve body 1 and valve deck 4 of the present invention is equipped with gasket 5.
Junction between screw rod 3 of the present invention and fixed lid 8 is equipped with O-ring seal 10.
The present invention drives valve plate 2 to rotate by screw rod 3, so that the stream that valve plate 2 mutually forms water inlet 11 with water outlet 12
Chamber realizes the movement opened and closed.
