Description
Technical field:
This utility model relates to gate valve, particularly relates to a kind of pneumatic butt-holding sluice valve.
Background technology:
Pneumatic butt-holding sluice valve enters China from the eighties.Less than in the vicennial time, its range is from general
Logical field extend to the most wide all trades and professions.From the coal separation of mine power plant, discharge refuse, deslagging.Develop into the dirt in city
Water processes, and has developed into the special pipeline systems such as food, health, medicine from general industrial pipeline.Extra-thin gate valve is with it
Volume is little, flow resistance is little, installation lightweight, easy, the advantage such as quick detachable, pneumatic butt-holding sluice valve thoroughly solves common gate valve, flat
What the flow resistance of the class valves such as plate gate valve, ball valve, stop valve, regulation valve, butterfly valve was big, weight is big, it is difficult to install, floor space is big etc. doubts
Difficult problem.
Pneumatic gate valve is to control valve with pneumatic actuator, thus realizes a kind of valve of the on an off of valve, is used for
Requiring fast shut-off or the occasion of unlatching, it can be divided into upper and lower two parts, and top half is pneumatic actuator, and the latter half is
Valve.
The most easily there is leakage phenomenon in pneumatic butt-holding sluice valve, needs to improve, and meets long-term
It is operated in highly corrosive environments.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of pneumatic butt-holding sluice valve, and structure sets
Rationally, the upper and lower side of flashboard has excellent sealing property to meter.
The technical solution of the utility model is as follows:
Pneumatic butt-holding sluice valve, including valve body, the left and right of valve body is respectively arranged at two ends with inlet and outlet, and valve body upper end is installed
Having support, pedestal upper end to be provided with Pneumatic actuator, the piston-rod lower end of Pneumatic actuator is provided with valve rod, and its feature exists
In, described valve rod fixes through support the flashboard up and down with in valve body valve pocket, and flashboard lower edge is wedge shaped, institute
The lock groove matched with flashboard it is provided with bottom the valve body valve pocket stated；The upper end of described valve body is provided with airtight and watertight padding groove, and sealing is filled out
Being filled with the airtight and watertight padding being positioned at flashboard both sides in hopper, airtight and watertight padding is arranged over the pressing plate being sleeved on flashboard, on pressing plate
End screws and is provided with bolt connection piece, and bolt connection piece is through pressing plate and is fixed on valve body, and it is close that pressing plate lower end extend into filler
Sealing groove is interior and compresses airtight and watertight padding.
Described pneumatic butt-holding sluice valve, it is characterised in that described lock groove wherein side cell wall be processed into under flashboard
The inclined-plane that end lozenges matches, another sidewall of lock groove is provided with upper sealing ring, the lower seal matched with flashboard non-wedge face
Circle.
Described pneumatic butt-holding sluice valve, it is characterised in that described upper sealing ring uses soft seal, lower seal uses
Hard sealing.
The utility model has the advantages that:
This utility model novel in structural design, flashboard can effectively prevent the sealing leak problem caused because of corrosion, carry
High sealing property, long-term working stability is good.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 be this utility model flashboard with lock groove location coordinate figure.

Being provided with support 2, support 2 upper end is provided with Pneumatic actuator 3, and the piston-rod lower end of Pneumatic actuator 3 is provided with valve rod
4, valve rod 4 fixes through support 2 flashboard 5 up and down with in valve body valve pocket, flashboard 5 lower edge wedge shaped 6, valve body
The lock groove 7 matched with flashboard it is provided with bottom 1 valve pocket；The upper end of valve body 1 is provided with airtight and watertight padding groove, is filled with in airtight and watertight padding groove
Being positioned at the airtight and watertight padding 8 of flashboard both sides, airtight and watertight padding 8 is arranged over the pressing plate 9 being sleeved on flashboard, and pressing plate 9 upper end screws peace
Equipped with bolt connection piece 10, bolt connection piece 10 is through pressing plate 9 and is fixed on valve body 1, and pressing plate 9 lower end extend into packing seal
Groove is interior and compresses airtight and watertight padding 8.
Lock groove 7 wherein side cell wall is processed into the inclined-plane 13 matched with flashboard lower end lozenges, on another sidewall of lock groove
It is provided with upper sealing ring 11, the lower seal 12 matched with flashboard non-wedge face.
Upper sealing ring 11 uses soft seal, lower seal 12 to use hard sealing, dual-seal, can improve flashboard further
The sealing property of lower end.
