In order to provide a kind of media transmitting tunnel which can resist high temperature and pressure and the corrosion, and it can expand with the cavity, the invention provides a kind of tunnel made up of media supplying pipe, sliding sleeve, metal extensible pipe, sealing device and connection flange, it accomplishes the change in length through the sliding extending of the metal extensible pipe, it realizes to supply media which can resist high temperature, high pressure and corrosion to the moving cavity.
Description
Technical field
The present invention relates to a kind ofly in chemical industry, to be used in the tube equipment, particularly foam forming machine for the cavity volume conveyance fluid medium that moves to cool off, blowdown, heating, dry medium transport tube equipment.
Background technique
At present, in the foam forming machine industry, because pipeline must have expanding-contracting action cooperating moving of cavity volume, so the pipeline that fed sheet of a media enters mobile cavity volume is generally the high pressure resistant rubber hose shown in the mark 9 among Fig. 3, and the rubber hose flexibility is good, bending radius is little.But inner wall coarse, friction factor are big, and because the high temperature or the corrosivity of flowing medium, high pressure rubber hose wears out easily, is corroded, breaks, working life is short, will change once in general 2～3 months, thereby cost is higher, and poor stability, product is also had pollution, and the big flowing medium of some corrosivity does not allow to use rubber hose to carry yet.Also useful metal flexible pipe in the practice, metallic hose can be high temperature resistant, ageing-resistant, but because the interior pipe of metallic hose is a bellows, and the pressure loss is big, and the flow velocity of allowing is low, bending radius is big, fracture easily.Therefore apply and be restricted.
Chinese patent 89214535.8 discloses the movable coupling arrangement of a kind of pressurized gas delivery line, it is made up of three movable sealing joints that are arranged in parallel and two sections rigid metal connecting tubes, and wherein movable sealing joint and connecting tube are fixedly connected by modes such as welding.After having connected, the two does not have slide relative.And the mobile dependence of this coupling arrangement is the traction of overhead traveling crane, and according to the length of overhead traveling crane stroke, the metal connecting tube of at every turn changing different length is to adapt to the transportation distance of different length.Therefore, it is not very convenient using.
Summary of the invention
For providing a kind of can high temperature high voltage resistant anticorrosive, again can be with the medium transport pipeline that stretches that moves of mobile cavity volume.
Technological scheme of the present invention is: a kind of movably flowing medium delivery line, comprise medium supply tube and medium transport pipe movably, it is characterized in that movably the medium transport pipe is made up of sliding sleeve, metal expansion pipe, seal arrangement and connecting flange, metal expansion pipe and sliding sleeve are link joint, metal expansion pipe can slide in sliding sleeve, one of metal expansion pipe is fixedlyed connected with connecting flange, be provided with seal arrangement between the tube wall of sliding sleeve and metal expansion pipe, sliding sleeve and medium supply tube are fixedly connected.
When this medium transport pipeline is applied to the flowing medium conveying; flange one end is connected with mobile cavity volume; when mobile cavity volume is promoted when fixedly cavity volume is drawn close or left by external force such as oil cylinders; mobile cavity volume drives this metal expansion pipe telescopic slide in sliding sleeve, changes with the length that realizes the medium transport pipeline.
Wherein, this metal expansion pipe can be a Stainless Steel Tube, and the internal diameter of this Stainless Steel Tube can be decided according to the actual requirements.When the internal diameter of this hard Stainless Steel Tube was 20mm～280mm, the pipeline operation reached the optimum state.
Sliding sleeve is wherein preferably connected to form by annular body and ring-type gland two-part, and the interior round side of body has a toroidal cavity, is provided with seal arrangement in the toroidal cavity.The left side of gland closely links to each other with body, and body can be connected by bolt or other modes with gland.
The preferred gland left end that is designed to is provided with a circle flange, and the right side of sliding sleeve body is provided with a groove and flange closely cooperates, and can reach better sealing effect.
In addition, can also intersect by several copper rings and several sealed circle at sliding sleeve and seal arrangement between the metal expansion pipe tube wall and assembly.For example being made up of seal ring that is positioned at two ends and the copper ring that is clipped in the middle, no matter be which kind of combination, is that the arrangement of seal ring is comparatively desirable with its right end face.The sealing circle can be made by sealing materials such as teflon, and copper ring has played the control guiding therein and reduced wear, and seal ring can stop flowing medium to external leakage.
When this device is applied to steeping molded machine industry, along with promoting mobile cavity volume, external force moves (outwards stretching) to fixing cavity volume, metal expansion pipe is corresponding to be stretched out, flowing medium is carried in mobile cavity volume or is discharged through metal expansion pipe by the medium supply tube, along with mobile cavity volume leaves fixedly cavity volume, metal expansion pipe also bounces back in the Seal cage of being made up of medium supply tube and sliding sleeve and Sealing.All running is controlled automatically by computer.
Certainly, thereby also can directly drive the flexible side-to-side movement that drives mobile cavity volume of metal expansion pipe by external force, near or leave fixedly cavity volume.
The delivery line of this flowing medium can be applicable to steep in molded machine industry and other the chemical industry, as cooling tube, heating pipe, drying tube or drain pipe etc., carries corresponding medium.Can work in-30 ℃～300 ℃ temperature range, working pressure can reach 16Kg, and test pressure can reach 200Kg.
Thus, this fluid delivery pipeline both can change the length of removable delivery pipe by the telescopic slide of metal expansion pipe, to cooperate moving of mobile cavity volume, can adapt to the conveying requirement of High Temperature High Pressure or active sulfur body medium again, long service life, cost is low, and is not only safe but also pollution-free, and safeguard easily, so have wide practical use.
