Specific embodiment
Embodiments of the present invention is further illustrated with reference to the accompanying drawing:
As shown, a kind of full floating double containment high temperature gate valve, including valve body 1, valve plate 2, valve rod 3, the valve plate 2 are inserted into valve
In body 1, the valve plate 2 is connected with valve rod 3, and the valve rod 3 is connected with operation handwheel, and two are formed in the valve body 1 vertically
The sliding rail 13 of arrangement, the valve plate 2 are arranged between two sliding rails 13, under the driving of valve rod 3, can slide up and down along valve body 1.
It is additionally provided with relocation mechanism on the valve plate 2, by the relocation mechanism, so that valve plate 2 can be horizontal in opening-closing process
To floating, so that valve plate 2, between opening and closing state, there are certain offsets.
The sealing surface 11 that cooperation can be sealed with valve plate 2, the valve body 1 of 11 outer ring of sealing surface are formed on the valve body 1
On be formed with ring-shaped depression slot 12, be equipped with elastic sealing ring 4 in the ring-shaped depression slot 12, the elastic sealing ring 4 is in freedom
Lateral distance under state between valve plate 2 is less than the lateral distance between sealing surface 11 and valve plate 2.
Wherein, the valve body 1 is formed using Q345B metal steel integral solder, and the valve plate 2 and elastic sealing ring 4 are equal
Be made of SUS304 stainless steel material, thermal stability is good, and is able to achieve in structure high temperature deformation compensation, can 450 DEG C with
Lower normal work can be well adapted for worst hot case, and guarantee sealing.
Full floating double containment high temperature gate valve using the above structure, by between the sealing surface 11 and valve plate 2 of valve body 1
First layer sealing is formed, forms second layer sealing between elastic sealing ring 4 and valve plate 2, thus realize double-layer seal, it can not only
Meet the seal request of different system pressures, and is further ensured that sealing performance.
Since the setting of elastic sealing ring 4 is in 11 outer ring of sealing surface, and it is arranged on valve body 1 and is formed in ring-shaped depression slot 12,
When valve is closed, elastic sealing ring 4 can be avoided to be contacted with the direct of medium flow field, therefore ensure that the nothing of elastic sealing ring 4
Abrasion cooperates the laterally floating of valve plate 2 to be arranged without deformation, so that valve plate 2, in opening-closing process, elastic sealing ring 4 can
It pushes valve plate 2 open, valve plate 2 is avoided, with the direct contact wear of sealing surface 11, to avoid the abrasion of sealing surface 11 in opening-closing process, because
This sealing surface 11, elastic sealing ring 4, the wear problem of valve plate 2 are all seldom, and while guaranteeing sealing, can greatly increase it makes
Use the service life.
As shown, the relocation mechanism is arranged on the other end of 2 opposing sealing surfaces 11 of valve plate, including lifting nut
5, nut positioning seat 6, locating support 7, vertical plate 8, sliding pin 9.
5 center of lifting nut be equipped with longitudinally disposed threaded hole 51, the valve rod 3 be screw rod, and with threaded hole 51
It matches, the two sidewalls of the lifting nut 5 are equipped with guide pad 52；The nut positioning seat 6 is fixedly mounted on 2 upside of valve plate
Medium position, the nut positioning seat 6 are equipped with mounting groove 61 compatible with lifting nut 5, the two sides of the mounting groove 61
Wall is equipped with the first guide groove 62 being obliquely installed, and the lifting nut 5 is arranged in mounting groove 61, and guide pad 52 is led with first
It is slidably matched to slot 62；In 2 two sides of valve plate, the locating support 7 is equipped with several second be obliquely installed and leads for the setting of locating support 7
To slot 71, and the bottom edge of the locating support 7 is lower than the bottom edge of valve plate 2；The vertical plate 8 setting is described vertical in 2 both sides of the edge of valve plate
Plate 8 is equipped with dowel hole 81 corresponding with the second guide groove 71；The sliding pin 9 passes through the second guide groove 71 and dowel hole
81 settings, connection board 8 and locating support 7.
When closing valve, by handwheel rotary valve rod 3, valve rod 3 drives valve plate 2 downward by cooperating with lifting nut 5
Movement, during the shutdown process, locating support 7 can be bottomed out first, stop downwards, and valve rod 3 continue rotation when, drive valve plate 2 continue to
Lower movement, at this point, due to the effect of the second guide groove 71, sliding pin 9 on locating support 7, so that valve plate 2 is along the second guide groove 71
Horizontal sliding pushes sealing surface 11 to, meanwhile, lifting nut 5 also in the mounting groove of nut positioning seat 6, due to guide pad 52 with
The effect of first guide groove 62 pushes valve plate 2 to sealing surface, and valve rod 3 is still maintained at primitive axis centre bit at this time, while making valve
Plate successively fits with elastic sealing ring 4, sealing surface 11, realizes two way seal.
When Open valve, valve rod is reversely rotated by handwheel, valve rod 3 drives valve plate 2 by cooperating with lifting nut 5
It moves upwards, in opening process, valve plate can be separated from rapidly with sealing surface 11 and, avoid under the action of elastic sealing element 4
Fretting wear occurs with sealing surface 11.
In addition, the nut positioning seat 6 is bolted connection on valve plate 2, the vertical plate 8 is then integrated with valve plate 2
Molding, and stiffener plate 82 is formed between the vertical plate 8 and valve plate 2, guarantee its intensity requirement, structure is simple, easy for installation.
The elastic sealing ring 4 is welded by its outer ring and valve body 1, and inner ring is obliquely installed towards 2 direction of valve plate, forms it
Elastic property.
4 inner ring of elastic sealing ring forms bending setting, including sealed with valve plate 2 sealing 41, can be supported with valve body 1
The contact portion 42 of touching, the interconnecting piece 43 for connecting sealing 41 and contact portion 42, the section of the elastic sealing ring 4 are in " J " type knot
Structure, when the valve is closed, valve plate 2 contact sealing, while its contact portion 42 and the ring-shaped depression slot 12 of valve body 1 with sealing 41
End face contact, mutually compresses, and guarantees contact sealing.
