Blade described in the utility model and valve body up and down contacted position, two side are respectively arranged with cross section and are Z-shaped blend stop, and the circular arc square wave at blend stop and adjacent blades edge overlaps.
Seal in the circular arc square wave that is located at adjacent blades lap-joint described in the utility model and blade and valve body the two side seal that the position is provided with that contacts up and down all are that cross section is the silicon hollow seal adhesive tape that ellipse adds side, and its position, side plane is fitted in the circular arc square wave inboard that overlaps blade.
Seal between blade described in the utility model and the valve body left and right sides wall is the quad seal adhesive tape, and the quad seal adhesive tape is fixed on the left and right sides wall of valve body, and its fixed position is pressed the rotation direction of blade and set, and staggers with blade normal rotation track.
The material of seal described in the utility model can be selected ethylene methacrylic silicon rubber for use.
Compare with existing common airtight valve, the utlity model has following characteristics:
1. the sealing between blade and the blade adopts cross section to be the oval silicon hollow seal adhesive tape that adds side, the position, side plane of sealing joint strip is fitted in the inboard of overlap joint blade circular arc square wave, valve is in off position the time, two blades overlap mutually and compress the ovaloid seal adhesive tape, form airfast plate structure, its advantage is that sealing joint strip is all wrapped up by the square wave circular arc of two blades, avoids directly contacting with pyrotechnics, can improve the high temperature resistant temperature of sealing joint strip, prolong the time that sealing joint strip is burnt out.
2. contacting of the upper and lower blade of airtight valve and valve body in circular arc square wave inboard, in the time of in off position, valve body is provided with " Z " type shelves bar, and " Z " type blend stop blocks the rotation of blade, and compresses sealing joint strip, makes blade and upper and lower valve body not have the gap and leaks out.
3. the opposite direction of rotating in the blade both sides is adopted in the sealing of blade and valve body left and right sides wall, fire-resistant silica gel strip with square is molded into the sealing joint strip similar to the blade profile shape, with angle type blend stop fixing seal bar, in the time of in off position, sealing joint strip is pushed by blade, and the gap is sealed fully.
4. use the utility model type airtight valve, leakage rate is reduced to less than 1%, and the permission operating temperature is-60 ℃～280 ℃, can obviously improve the effect of ventilation, flue gas control, under fire condition, can effectively cut off burning things which may cause a fire disaster, prevent spreading of fire, for rescue personnel and property win more valuable time.
Below in conjunction with accompanying drawing and concrete mode the utility model is described further.
