Abstract
The utility model discloses an inner-outer differential pressure type lock sealing structure, and the utility model is suitable for the sealing of the pressure vessels which are composed of a pot body and a pot cover. A V-shaped ring groove is arranged on the corresponding position of the contact surface of the two flanges respectively. An elastic ring whose sectional outer diameter is smaller than the height of the diamond is arranged in the rhombic ring interval of the two V-shaped ring grooves relatively. In addition, a bolt is fixed on the flange of the pot body. Key-shaped strip thought holes which have the same quantity as the bolts are arranged on the flange of the pot cover. The large hole diameters of the thought holes are larger than the diameters of the nuts. The diameters of the small holes are larger than the diameters of the nuts. The utility model has the advantages of simple structure, good sealing effect, easy fabrication and low cost. J[-130].
Description
The utility model relate to the pot type pressurized container tank body and the lid between utilize the tank body inside and outside differential pressure to make a kind of structure of its lock sealing.
Original bolt clip compact form lock sealing structure is replaced by pressure kettle lock sealing formula, and the connection place of latter's tank body and cover needs diffusion zone.Turning circle lock sealing structure basic principle and pressure cooker type lock sealing structure that happy safe ［ Locite ］ company of Japan and the U.S. produces are similar, many turning circles, and need diffusion zone.Above-mentioned two kinds of structures are processing difficulties not only, and distortion easy to wear.The bell jar pneumatic-typed lock sealing device that B. P. GB2094674A introduces is that tank body and cover combine as a whole, cover on backed non-with it on the polycrystalline substance of one as same cover, this bell jar like this will be according to the high equipped cylinder that surpasses jar high-stroke of jar by cylinder control buck tightening seal.It is very difficult making large-scale like this cylinder.
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of simple in structure, good sealing effect, lock sealing structure easy to manufacture.
The purpose of this utility model can reach by following measure: a kind of inner-outer differential pressure type lock sealing structure, be applicable to the sealing of the open-close type pressurized container of forming by tank body and cover, it is to fix with the flange that bolt will be located on tank body and the cover periphery, it is characterized in that corresponding position respectively is provided with the V-ring groove on the face of two flanges contact, the two V-ring grooves annular gap that assumes diamond in shape relatively, it is built-in with the cross section external diameter less than the high elastic ring of rhombus.
The purpose of this utility model can also reach by following measure: the screw rod height that exposes all equates to be a bit larger tham on the flange that is bolted to tank body of cover flange thickness, the cover flange is provided with the key shaped strip through hole identical with the bolt number, the one side diameter in this hole is greater than the nuts diameter, and the opposite side diameter is then greater than screw rod and less than the diameter of nut.
The utility model mainly is by locking and seals dimerous.In the open-close type pressurized container of forming by tank body and cover, be respectively equipped with flange on the contacted periphery of cover and tank body.Be fixed with several bolts on the flange of tank body, the screw rod height that these bolts are exposed at the flange plate outside all equates, and is a bit larger tham the thickness of cover flange.A stationary axle is set in the tank flange side, is furnished with a wrench on the axle, it can be fixed on the axle, also can be movable.Be provided with " key " shape cylindrical void identical with the bolt number on the cover flange, these strip through holes are to be connected together by straight transitions by half aperture and part macropore.The one side diameter in this hole is greater than the diameter of nuts, and the diameter of opposite side is a bit larger tham the diameter of screw rod and less than the diameter of nuts.Be provided with a pin in the side of cover flange, when the closing pressure container that the pin on the cover flange is relative with the bearing pin position on the tank body, bolt on the tank flange passes the through hole on the cover flange at this moment, two flanges are in contact with one another, move wrench then, because the pin on the cover is positioned at the jaw of wrench, cover then rotates the mobile position, make bolt move on in the small diameter bore, pressurized container then is lockable.
Respectively be provided with a V-shaped groove in the corresponding position of two flange contact facings.Two flanges contact relatively when cover covers on tank body, V-shaped groove on the flange annular gap that also assumes diamond in shape relatively, it is built-in with a cross section and is the circular preferably seal ring of the elastic material of ring, the external diameter in its cross section is less than the height in rhombus gap, and seal ring can move in the rhombus annular gap like this.When being pumped into negative pressure in the jar or pressurize in jar, jar external and internal pressure is inequality, and seal ring moves axially at inside and outside differential pressure effect lower edge tank body, and the slit between two flanges is sealed.
The utility model has following advantage compared to existing technology: simple in structure, easy manufacturing, long service life, cost are low.Easy to operate, reduction labor intensity, good sealing effect, degree of vacuum can reach 0.1MPa, and especially inside and outside differential pressure is big more, sealing effect is good more.
Utilize the example shown in the accompanying drawing, the utility model is described in further detail.
Fig. 1 is the partial sectional view of inner-outer differential pressure type lock sealing structure.
Fig. 2 is the utility model cover and tank flange assembling schematic representation.
Fig. 3 is the partial top view of the utility model cover flange.
In inner-outer differential pressure type lock sealing structure shown in Figure 1, on 3 contacted of tank flange 4 and cover flanges, corresponding position respectively is provided with a V-ring groove 8 between bolt and the tank body, the two V-shaped grooves annular gap that assumes diamond in shape relatively when two flanges contact relatively, it is built-in with a ring cushion rubber 5, and its cross section external diameter is less than the height in rhombus gap.
In tank body shown in Figure 2 and cover flange assembling schematic representation, respectively be provided with flange at the periphery of tank body 2 and cover 1.With nut 7 20 contour bolts 6 are fixed on the flange of tank body, the screw rod height that these bolts are exposed at the flange plate outside all equates, is a bit larger tham the cover flange thickness.A stationary axle 11 is set in the tank flange side, and axle is provided with a locking wrench 12.The pin 10 of cover flange side just is positioned at the jaw of wrench, on the cover flange, be provided with the key shaped cylindrical void 9 identical as shown in Figure 3 with the bolt number, these holes are connected together by straight transitions by half aperture and part macropore, the diameter of its macropore is greater than the nut diameter, and hole diameter is a bit larger tham screw diameter and less than the diameter of nut.
