Description
Technical field
The utility model belongs to valve field, more particularly to a kind of gate valve.The utility model is suitable for abrasion, corrosion
The control valve of property slurry medium pipeline.
Background technology
Common gate valve is generally made of valve body, valve seat, flashboard, valve rod, and valve seat is mounted on valve body and imports and exports passway, flashboard
Both sides cooperate with valve seat and seal, and packing seal is used between valve rod and valve body.Its major defect is medium to valve body, valve seat
With larger erosive wear and corrosivity, slurry medium easily deposits 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.
Invention content
The purpose of this utility model is for shortcoming of the existing technology, provides a kind of antiscour, wear-resisting, corrosion-resistant,
The wear-resisting Parallel Slide Valves of lining rubber tape scraper of good seal performance.
The technical solution of the utility model includes valve body, flashboard, valve rod, stent, handwheel, in valve rod lower end and flashboard upper end
Between be fixedly connected, valve rod upper end is threadedly coupled by valve stem nut with handwheel；Mainly valve body by symmetrical structure left valve barrel and
Right valve barrel is bolted, and left valve barrel and right valve barrel channel and end face of flange integrally vulcanize abrasive rubber layer, in left valve
The passway of body and the opposite end face of right valve barrel is formed respectively with U-shaped step, the U-shaped sealing that U-shaped step is interconnected to constitute in both sides
The U-shaped outer end face of the U-shaped seal receptacle of installation in slot, the U-shaped seal receptacle and flashboard, which cooperates, forms sealing pair；U-shaped seal receptacle is adopted
With abrasive rubber material, being located at valve channel center line lower portion has the semi arch knot equal with valve channel diameter
Structure；Transverse sealing slot is formed respectively in the left valve barrel of U-shaped seal groove upper end and right valve barrel end face, in the transverse sealing slot of both sides
The rubber weather strip of installation and the cooperation of flashboard both sides flat seal respectively is embedded in rubber weather strip and is connect with two side plane of flashboard
Tactile transverse 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 both sides plane contact respectively in the both sides up and down of the tetrafluoro horizontal stripe.
The utility model has the advantages that valve body assembles after vulcanizing abrasive rubber layer using split type processing, it is easy to process
The control of size improves machining accuracy and the fit precision with flashboard, has antiscour, wear-resisting, corrosion-resistant, good seal performance etc.
Feature.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is partial structurtes enlarged drawing at I in the utility model Fig. 1.
Specific embodiment
The wear-resisting Parallel Slide Valves of lining rubber tape scraper as shown in Figure 1, including valve body 3, flashboard 2, valve rod 10, stent 9, handwheel 12,
10 lower end of valve rod and flashboard are 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
Installation packing padding 7 is compressed by gland 8 between body 3 and valve rod 10；Valve body 3 is led to by the left valve barrel and right valve barrel of symmetrical structure
It crosses and is bolted, convenient for the machining control in each face of valve chamber, improve the fit precision between flashboard 2 and valve body 3, left valve barrel
Integrally vulcanize abrasive rubber layer with right valve barrel channel and end face of flange, effective protection medium is washed away and worn to valve body 3, is improved
The antiscour and wear-resisting property of valve body 3 are formed respectively with U-shaped step, two in the passway of left valve barrel and the opposite end face of right valve barrel
The U-shaped seal receptacle 1 of installation in the U-shaped seal groove that the U-shaped step in side is interconnected to constitute, the U-shaped outer end of the U-shaped seal receptacle 1 and flashboard 2
Face, which cooperates, forms sealing pair, realizes two way seal；U-shaped seal receptacle 1 uses abrasive rubber material, is located at 3 channel of valve body
Center line lower portion has the semi arch structure equal with 3 channel diameter of valve body, makes valve chamber bottom un-grooved, without dead angle, keeps away
Medium is exempted from and the problem of flashboard 2 is caused to be not closed completely is accumulated in valve chamber；At the left valve barrel of U-shaped seal groove upper end and right valve barrel end
Transverse sealing slot is formed respectively in face, the rubber that installation coordinates with 2 both sides flat seal of flashboard respectively in the transverse sealing slot of both sides
Glue sealing strip 6 is embedded in the transverse metal scraping blade 4 with 3 both sides plane contact of flashboard, transverse metal scraping blade 4 in rubber weather strip 6
The medium being adhered on 2 both sides sealing face of flashboard is struck off in 2 opening-closing process of flashboard, makes valve switch process that there is self-cleaning work(
Can, it can be with the sealing performance of effective 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 both sides up and down of horizontal stripe 5 be embedded in respectively with the transverse metal scraping blade 4 of 2 both sides plane contact of flashboard, improve lumen self-cleaning property and
Sealing performance.
