Abstract

The invention relates to the field of sealing of steaming tanks, in particular to a sealing device of a steaming tank. A cover body is arranged on a tank opening of a steaming tank body, a sealing ring is arranged between the attaching face of the cover body and the attaching face of the tank opening, the sealing ring is contained in a groove formed in the tank opening of the steaming tank body or in a groove formed in the cover body, and the groove bottom of the groove is communicated with a pressure air source through a through path. The sealing ring is adopted and clamped in the annular groove, the groove bottom of the groove is communicated with the pressure air source, tight attaching is made to be formed between the sealing ring and the annular groove through high pressure air, and the air sealing performance of the tank body and a movable door is ensured.

Description

A kind of sealing arrangement that steams jar

Technical field

The present invention relates to steam the field of sealing technology of jar, particularly a kind of sealing arrangement that steams jar.

Background technology

At present, steam jar and be widely used in industries such as food processing, pharmacy, chemical industry.Article to be processed are put into and are steamed tank, utilize thermal source produce hot vapour make tank interior pressure and temperature be stabilized in the claimed range of processing.In the 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 slit of filling lid and tank body junction guarantees the air-tightness of lid and tank body junction.Weak point is in the prior art: rubber pad is easy deformation in the process of clamping, and rubber pad is extruded clamping place easily, causes gas leakage; In addition, the mode complicated operation of this clamping rubber pad, the air-tightness of steam autoclave can not get guaranteeing.

Summary of the invention

The object of the present invention is to provide a kind of sealing arrangement that steams jar to solve the cylindrical shell of steaming jar and the reliability of lid sealing.

For realizing above purpose, the technical solution used in the present invention is: a kind of jar of door seal device, a jar mouthful place of steaming tank arranges lid, between described lid and jar mouthful binding face seal ring is set, described seal ring is placed in the groove that arranges on the jar mouthful place of steaming tank or the 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 present invention: adopt above-mentioned seal ring that it is contained in the toroidal cavity, the bottom land place of groove is communicated with pressure gas source by path, high pressure gas make seal ring and toroidal cavity form and fit tightly, guaranteed the air-tightness of tank body and dodge gate.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 6, the present invention done being described in further detail:

A kind of sealing arrangement that steams jar, in conjunction with shown in Figure 3, a jar mouthful place of steaming tank 10 arranges lid 20, between lid 20 and jar mouthful binding face seal ring 30 is set, seal ring 30 is placed in the groove 11 that arranges on the jar mouthful place of steaming tank 10 or the 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 a jar mouthful place all is feasible, only needs that the path 40 of pressure gas source and pressure gas source is done the adjustment of corresponding position and gets final product.Below just seal ring 30 is contained in jar mouthful scheme at place and describes: seal ring 30 is placed in the jar mouthful groove 11 that the place arranges that steams tank 10, and the bottom land place of groove 11 is communicated with pressure gas source by path 40.

Further, be " U " type structure in conjunction with Fig. 3,4,6 seal rings, 30 integral body for ring-type and cross section, the two ends of seal ring 30 openings are provided with the flange 31 of outside rollover; The cross section of described groove 11 is closing in shape setting small for mouth and large for cavity, flange 31 is positioned at groove 11 larger-size vallecular cavities, seal ring 30 openings point to vallecular cavity and are contained in the less notch place of groove 11 sizes, for reaching the effect that fits 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, feed high pressure gas, on the part end face that is resisted against lid 20 tightly with the seal ring 30 that reveals, guaranteed air-tightness.In conjunction with Fig. 2, shown in Figure 3, lid 20 is how to open and/or closed from tank body 10, in another of the inventor part application detailed explanation is arranged, and does not do herein and gives unnecessary details.

Path 40 is communicated with pressure gas source, pressed gas can directly obtain by the high pressure gas from steam jar, only needing to stretch out pipeline in tank body is communicated with path 40, the control cock of fit on gas can be regulated the tolerance that is passed into vallecular cavity 11 bottoms on the pipeline that stretches out, and it is by realizing in tank body 10 punching and being communicated with of path 40 that described vallecular cavity 11 is connected with path 40.
