Description
Technical field
This utility model is related to a kind of knife gate valve, more particularly to a kind of corrosion proof and leakproof knife gate valve.
Background technology
Knife gate valve enters China from the eighties, and in less than the vicennial time, its use range expands from general field
More wide all trades and professions are opened up, coal separation, discharge refuse from mine power plant, deslagging have developed into the sewage disposal in city, from
General industrial pipeline has developed into the special pipeline system such as food, health, medicine.When knife gate valve is closed, sealing surface can be with
Rely only on pressure medium to seal, i.e., press to the valve seat of opposite side to ensure sealing surface by the sealing surface of flashboard by pressure medium
Sealing, here it is self sealss.Traditional knife gate valve corrosion-resistant, anti-wear performance are poor, and heat-resisting quantity and lower temperature resistance are weak, no
It is easily installed and safeguards, take up room big, practicality is weak, poor sealing performance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of corrosion proof and leakproof knife gate valve, and its good corrosion resistance is resistance to
Mill property is strong, and heat-resisting quantity and lower temperature resistance are good, it is easy to installs and safeguards, takes up room little, practical, good seal performance.
This utility model is solving above-mentioned technical problem by following technical proposals：A kind of corrosion proof and leakproof knife gate valve,
Which includes handwheel, valve rod, valve gap, fixing screws, flashboard, protective block, valve pocket, anti-corrosion bar, screw, flashboard chamber, pipe box, sealing
Bar, the second standard component, sealing block, handwheel are located above valve gap, and valve rod is located inside valve gap, and valve gap is connected with protective block, fixed
Screw is fixed on protective block, and flashboard is located at flashboard intracavity, and protective block is located at outside valve pocket, and valve pocket is located above flashboard chamber, anti-corrosion
Bar is located on the right side of the second standard component, and on pipe box, flashboard chamber is located in pipe box screw, and pipe box is connected with anti-corrosion bar, sealing strip
It is connected with flashboard, the second standard component is connected with sealing block, sealing block is located at below valve pocket.
Preferably, the pipe box is shaped as annular.
Preferably, the pipe box adopts steel alloy pipe box.
Preferably, the handwheel outward flange is waveform.
Preferably, the fixing screws adopt soket head cap screw.
Positive effect of the present utility model is：This utility model good corrosion resistance, wearability are strong, heat-resisting quantity and
Lower temperature resistance is good, it is easy to installs and safeguards, takes up room little, practical, good seal performance.
Description of the drawings
Structural representations of the Fig. 1 for this utility model corrosion proof and leakproof knife gate valve.
Specific embodiment
This utility model preferred embodiment is given below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
As shown in figure 1, this utility model corrosion proof and leakproof knife gate valve includes handwheel 1, valve rod 2, valve gap 3, fixing screws 4, lock
Plate 5, protective block 6, valve pocket 7, anti-corrosion bar 8, screw 9, flashboard chamber 10, pipe box 11, sealing strip 12, the second standard component 13, sealing block
14, handwheel 1 is located above valve gap 3, and valve rod 2 is located inside valve gap 3, and valve gap 3 is connected with protective block 6, and fixing screws 4 are fixed on anti-
In protecting block 6, flashboard 5 is located in flashboard chamber 10, and protective block 6 is located at outside valve pocket 7, and valve pocket 7 is located above flashboard chamber 10, anti-corrosion bar 8
On the right side of the second standard component 13, on pipe box 11, flashboard chamber 10 is located in pipe box 11 screw 9, and pipe box 11 is connected with anti-corrosion bar 8
Connect, sealing strip 12 is connected with flashboard 5, the second standard component 13 is connected with sealing block 14, sealing block 14 is located at below valve pocket 7.
Pipe box 11 is shaped as annular, so strengthens comfortable feel degree, prevents having the corner angle surprisingly to scratch when carrying.
Pipe box 11 adopts steel alloy pipe box, so strengthens corrosion resistance, wearability, heat-resisting quantity and lower temperature resistance.
1 outward flange of handwheel is waveform, so strengthens frictional force, is easy to rotate handwheel.
Fixing screws 4 adopt soket head cap screw, are so easy to fasten, dismantle, are difficult to slide angle, reduce working place.
Operation principle of the present utility model is as follows：First, when valve is closed, rotates counterclockwise handwheel and drive valve
So as to open flashboard, after flashboard is opened, water is flowed out from flashboard chamber for bar motion, rotates clockwise handwheel, and flashboard cuts out, water retention fluid stopping
Go out.Valve gap is used to protect valve rod.Fixing screws are used for fixed protection block.Protective block is used for enhancing structure fastness.Valve pocket is used for
Protection valve rod.Anti-corrosion bar is used to improve antiseptic property.Screw is used for mounting screw and fixes pipe box.It is firm that pipe box is used for enhancing structure
Property.Sealing strip is used to strengthen sealing property.Second standard component is used for enhancing structure stability.Sealing block is used to strengthen sealing
Can, prevent leak.
In sum, this utility model good corrosion resistance, wearability are strong, and heat-resisting quantity and lower temperature resistance are good, it is easy to install
And maintenance, take up room little, practical, good seal performance.
Particular embodiments described above, the technical problem, technical scheme and beneficial effect to solution of the present utility model
Further described, it is be should be understood that to the foregoing is only specific embodiment of the utility model, not
For limiting this utility model, all any modifications within spirit of the present utility model and principle, made, equivalent, change
Enter, should be included within protection domain of the present utility model.
