Abstract

The utility model relates to the field of sealing of steaming tanks, in particular to a sealing device of a steaming tank. A cover is arranged at a tank mouth of a steaming tank body. A sealing ring is arranged between binding faces of the cover and the tank mouth. The sealing ring is placed at the tank mouth of the steaming tank body or in a groove formed in the cover. The bottom of the groove is communicated with a pressure gas source through a passage. The sealing ring is clamped in the ring-shaped groove, the bottom of the groove is communicated with the pressure gas source, and high-pressure gas enables the sealing ring and the ring-shaped groove to form close fit, so that gas tightness of the tank and a movable door is guaranteed.

Description

A kind of sealing arrangement of steaming pot

Technical field

The utility model relates to the field of sealing technology of steaming pot, particularly a kind of sealing arrangement of steaming pot.

Background technology

At present, steaming pot is widely used in the industries such as food processing, pharmacy, chemical industry.Article to be processed are put into steaming pot tank body, utilize thermal source produce hot vapour make tank interior pressure and temperature be stabilized in the claimed range of processing.In prior art, opening junction at tank body and lid arranges rubber pad, and use bolt etc. is fastenedly connected lid and tank body, compresses rubber pad, make rubber pad produce pressure distortion, the gap of filling lid and tank body junction guarantees the air-tightness of lid and tank body junction.In prior art, weak point is: rubber pad is easily distortion in the process of clamping, and rubber pad is easily extruded clamping place, causes gas leakage; In addition, the mode complicated operation of this clamping rubber pad, the air-tightness of steam autoclave can not be guaranteed.

Utility model content

The purpose of this utility model is to provide a kind of sealing arrangement of steaming pot to solve the cylindrical shell of steaming pot and the reliability of lid sealing.

For realizing above object, the technical solution adopted in the utility model is: a kind of tank door seal device, the tank mouth place of steaming pot tank body arranges lid, between described lid and tank mouth binding face, seal ring is set, described seal ring is placed in the groove arranging on the tank mouth place of steaming pot tank body or lid, and the bottom land place of described groove is communicated with pressure gas source by path.

Compared with prior art, there is following technique effect in the utility model: adopts above-mentioned seal ring to be contained in toroidal cavity, the bottom land place of groove is communicated with pressure gas source by path, high pressure gas fit tightly seal ring and toroidal cavity formation, have guaranteed the air-tightness of tank body and dodge gate.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 6, the utility model is described in further detail:

A kind of sealing arrangement of steaming pot, shown in Fig. 3, the tank mouth place of steaming pot tank body 10 arranges lid 20, between lid 20 and tank mouth binding face, seal ring 30 is set, seal ring 30 is placed in the groove 11 arranging on the tank mouth place of steaming pot tank body 10 or lid 20, and the bottom land place of groove 11 is communicated with pressure gas source by path 40.

Described seal ring 30 is arranged on lid 20 or tank mouth place is all feasible, only need do the adjustment of corresponding position to the path 40 of pressure gas source and pressure gas source.Below just seal ring 30 is contained in to tank mouth place scheme describe: seal ring 30 is placed in the groove 11 that the tank mouth place of steaming pot tank body 10 arranges, and the bottom land place of groove 11 is communicated with pressure gas source by path 40.

Further, whole for ring-type and cross section are " U " type structure in conjunction with Fig. 3,4,6 seal rings 30, the two ends of seal ring 30 openings are provided with the flange 31 of outside rollover; Described groove 11 cross section is closing in shape setting small for mouth and large for cavity, flange 31 is positioned at the larger-size vallecular cavity of groove 11, seal ring 30 openings point to vallecular cavity and are contained in the notch place that groove 11 sizes are less, for reaching the effect fitting tightly at lid 20, can be so that the part of seal ring 30 be emerging on the faying face of tank body 10 and lid 20, when covering lid 20, pass into high pressure gas, by on a part for the seal ring revealing 30 end face that is resisted against lid 20 tightly, guaranteed air-tightness.Shown in Fig. 2, Fig. 3, lid 20 is how from tank body 10, to open and/or closed, in the utility model people's another part of application, has detailed explanation, does not repeat herein.

Path 40 is communicated with pressure gas source, pressed gas can directly obtain by the high pressure gas from steaming pot, only need be communicated with path 40 from stretching out pipeline in tank body, on the pipeline stretching out, the control cock of fit on gas can regulate being passed into the tolerance of vallecular cavity 11 bottoms, and it is to realize and being communicated with of path 40 by punching on tank body 10 that described vallecular cavity 11 is connected with path 40.
