Description
Technical field
The invention belongs to valve field, in particular to a kind of gate valve.The present invention is suitable for being situated between with abrasion, caustic slurry
The control valve of matter pipeline.
Background technique
Common gate valve is generally made of valve body, valve seat, flashboard, valve rod, and valve seat is mounted on valve body inlet and outlet passway, flashboard
Two sides and valve seat, which cooperate, to be sealed, and packing seal is used between valve rod and valve body.Its major defect is medium to valve body, valve seat
With biggish erosive wear and corrosivity, slurry medium is easy to deposit in valve chamber, influences flashboard and closes not in place, slurry appearance
It is easily adhered on flashboard both sides sealing face, abrasion is generated to lumen packing seal and sealing surface of seat, influences sealing performance.
Summary of the invention
The purpose of the present invention is being directed to disadvantage of the existing technology, a kind of antiscour, wear-resisting, corrosion-resistant, sealing are provided
The good rubber-lined sluice valve of performance.
Technical solution of the present invention includes valve body, flashboard, valve rod, bracket, handwheel, and valve rod lower end and flashboard upper end centre are solid
Fixed connection, valve rod upper end are threadedly coupled by valve stem nut with handwheel；Mainly valve body by symmetrical structure left valve barrel and right valve
Body is bolted, and left valve barrel and right valve barrel channel and end face of flange integrally vulcanize abrasive rubber layer, in left valve barrel and
The passway of the opposite end face of right valve barrel is formed respectively with U-shaped step, in the U-shaped seal groove that U-shaped step is interconnected to constitute in two sides
U-shaped seal receptacle is installed, the U-shaped outer end face of the U-shaped seal receptacle and flashboard, which cooperates, constitutes sealing pair；U-shaped seal receptacle is using resistance to
Rubber milling material, being located at valve channel center line lower portion has the semi arch structure equal with valve channel diameter；In U
It is formed respectively with transverse sealing slot in the left valve barrel of type seal groove upper end and right valve barrel end face, is pacified respectively in the transverse sealing slot of two sides
The rubber weather strip of dress and the cooperation of flashboard two sides flat seal is embedded in the cross with flashboard two sides plane contact in rubber weather strip
To metal scraping blade.
In above technical scheme, the tetrafluoro that cooperation is sealed against each other with two side plane of flashboard is embedded among rubber weather strip
Horizontal stripe is embedded in the transverse metal scraping blade with flashboard two sides plane contact in the two sides up and down of the tetrafluoro horizontal stripe respectively.
It is an advantage of the invention that valve body assembles after vulcanizing abrasive rubber layer using split type processing, size easy to process
Control, improve machining accuracy and the cooperation precision with flashboard, there are the spies such as antiscour, wear-resisting, corrosion-resistant, good seal performance
Point.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is partial structurtes enlarged drawing at I in Fig. 1 of the present invention.
Specific embodiment
Rubber-lined sluice valve as shown in Figure 1, including valve body 3, flashboard 2, valve rod 10, bracket 9, handwheel 12,10 lower end of valve rod with
Flashboard is fixedly connected among 2 upper end, and 10 upper end of valve rod is threadedly coupled by valve stem nut 11 with handwheel 12, valve body 3 and valve rod 10
Between by gland 8 compress installation packing padding 7；Valve body 3 is bolted by the left valve barrel and right valve barrel of symmetrical structure
It forms, convenient for the machining control in each face of valve chamber, improves the cooperation precision between flashboard 2 and valve body 3, left valve barrel and right valve barrel are logical
Road and end face of flange integrally vulcanize abrasive rubber layer, and effective protection medium is washed away and worn to valve body 3, improve the anti-of valve body 3
It washes away and wear-resisting property, U-shaped step is formed respectively in the passway of left valve barrel and the opposite end face of right valve barrel, in the U-shaped step in two sides
The U-shaped seal receptacle 1 of installation, the U-shaped outer end face phase interworking of the U-shaped seal receptacle 1 and flashboard 2 in the U-shaped seal groove being interconnected to constitute
It closes and constitutes sealing pair, realize two way seal；U-shaped seal receptacle 1 uses abrasive rubber material, is located under 3 channel centerline of valve body
Side section has the semi arch structure equal with 3 channel diameter of valve body, makes valve chamber bottom un-grooved, without dead angle, avoids medium
The problem of accumulation causes flashboard 2 to be not closed completely in valve chamber；In the left valve barrel of U-shaped seal groove upper end and right valve barrel end face respectively
It is formed with transverse sealing slot, the rubber weather strip with the cooperation of 2 two sides flat seal of flashboard is installed respectively in the transverse sealing slot of two sides
6, the transverse metal scraping blade 4 with 3 two sides plane contact of flashboard is embedded in rubber weather strip 6, transverse metal scraping blade 4 is in flashboard 2
The medium being adhered on 2 both sides sealing face of flashboard is struck off in opening-closing process, makes valve switch process that there is self-cleaning function, Ke Yiyou
The sealing performance of effect protection packing padding 7.
The tetrafluoro horizontal stripe 5 that cooperation is sealed against each other with 2 liang of side planes of flashboard is embedded among rubber weather strip 6, in the tetrafluoro
The two sides up and down of horizontal stripe 5 be embedded in respectively with the transverse metal scraping blade 4 of 2 two sides plane contact of flashboard, improve lumen self-cleaning property and
Sealing performance.
