Abstract
The utility model discloses a sealing flat gate valve and belongs to the technical field of gate valves. The sealing flat gate valve comprises a valve body, a hand wheel, a screw rod, a nut, a wedge-shaped gate plate, a flexible sealing strip and a sealing plate. The hand wheel is connected with the screw rod. The screw rod is connected with the wedge-shaped gate plate through a nut. A carrier roller sliding in a mode of being matched with the wedge-shaped gate plate is arranged on one side of the valve body. The sealing plate used for sealing is arranged on the other side of the valve body. The flexible sealing stripe is arranged between the wedge-shaped gate plate and the valve body. By the adoption of the wedge-shaped gate plate and the flexible sealing strip which are used in a matching mode, the sealing flat gate valve improves the sealing effect, overcomes the defects of a common flat gate plate, consumes less steel materials than a traditional gate valve, reduces production cost, is simple in structure and easy to maintain, and has pretty good practicality.
Description
Technical field
The utility model belongs to gate valve technical field, is specifically related to a kind of sealed flat gate valve.
Background technique
Plate valve is widely used in the fields such as metallurgy, industrial and mineral, water conservancy irrigation, closing and cutting off for media such as gas, water body, dust, it is that a kind of closure member is the slide-valve of parallel gate plate, and its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism.Traditional flashboard is slab construction, and sealing effect is not good, and flashboard is when opening, because medium answers the impact of pressure easily to cause material to be revealed; And traditional plate valve is full steel structure, cost of production is higher.
Model utility content
Goal of the invention: the purpose of this utility model is to optimize the structure of parallel gate plate, when improving sealing effect, reduces production costs.
Technological scheme: for realizing above-mentioned model utility object, the technical solution adopted in the utility model is:
Sealed flat gate valve comprises valve body, handwheel, screw mandrel, screw, wedge shape flashboard, flexible sealing strip and a shrouding, and described handwheel is connected with screw mandrel, and screw mandrel is connected with wedge shape flashboard by screw; In a side of described valve body, be provided with the carrying roller that coordinates wedge shape flashboard to slide, at the opposite side of described valve body, be provided with the shrouding for sealing; Between described wedge shape flashboard and valve body, be provided with flexible sealing strip.
Described screw mandrel is arranged on valve body by screw mandrel fixed base.
On described screw mandrel fixed base, be provided with sealed letter.
Between described screw mandrel fixed base and valve body, be provided with sealing gasket.
Beneficial effect: compared with prior art, wedge shape flashboard and flexible sealing strip that sealed flat gate valve of the present utility model is used in conjunction with by setting, not only improved the effect of sealing, overcome the defect that ordinary flat flashboard easily leaks, and this plate valve steel consumption is less than traditional plate valve, greatly reduce cost of production; Simultaneously sealing plate valve simple in structure, be easy to maintenance and safeguard, there is good practicability.
Accompanying drawing explanation
Fig. 1 is the plan view of sealed flat gate valve;
Fig. 2 is the side view of sealed flat gate valve.
Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are described, but protection domain of the present utility model is not limited to described embodiment.
As depicted in figs. 1 and 2, sealed flat gate valve comprises valve body 1, handwheel 2, screw mandrel 3, screw 4, wedge shape flashboard 5, flexible sealing strip 6 and shrouding 7, and handwheel 2 is connected with screw mandrel 3, and screw mandrel 3 is connected with wedge shape flashboard 5 by screw 4; In a side of valve body 1, be provided with the carrying roller 11 that coordinates wedge shape flashboard 5 to slide, at the opposite side of valve body 1, be provided with the shrouding 7 for sealing; Between wedge shape flashboard 5 and valve body 1, be provided with flexible sealing strip 6.Wherein, screw mandrel 3 is arranged on valve body 1 by screw mandrel fixed base 8, is provided with for sealing the sealed letter 9 of screw mandrel 3 on screw mandrel fixed base 8, between screw mandrel fixed base 8 and valve body 1, is provided with sealing gasket 10.
Working procedure: by handwheel 2, screw mandrel 3 and screw 4 drive wedge shape flashboards 5 along carrying roller 11 in the interior slip of valve body 1, when wedge shape flashboard 5 contacts with flexible sealing strip 6, wedge shape flashboard 5 and flexible sealing strip 6 to contact meeting more and more tighter, to reach zero leakage; By sealed letter 9 is set, the end sealing by screw mandrel 3, prevents material from leakage; By sealing gasket 10 is set, improve sealing effect.
Wedge shape flashboard and flexible sealing strip that sealing plate valve is used in conjunction with by setting, not only improved the effect of sealing, overcome the defect that ordinary flat flashboard easily leaks, and this plate valve steel consumption is less than traditional plate valve, greatly reduces cost of production; Simultaneously sealing plate valve simple in structure, be easy to maintenance and safeguard, there is good practicability.
