Description
Technical field
The utility model belongs to vacuum pipe vulcanizing equipment field more particularly to a kind of vulcanization for vacuum equipment is blind
Plate.
Background technology
At present, the pipeline of vacuum equipment does liner frequently with rubber slab, can improve the corrosion-resistant and shock proof property of pipeline
Can, when pipeline is laid with, liner first is done using unvulcanized rubber slab in the duct, after the completion of pipeline is laid with, reuses steam
Rubber slab is vulcanized, makes to generate crosslinking between the vulcanizing agent in offset plate and rubber molecule, forms tridimensional network, rubber can be improved
The mechanical performance and corrosion resistance of glue, in vulcanization, frequently with blind plate sealing at flange hole, to Flange Plane at angular rotation of flange
Since blind plate sealing is tighter on the inside of bolt hole, steam can hardly enter and be unable to tight cure in sulfidation, unvulcanized
Rubber slab mechanical performance it is poor, the service life of equipment can be reduced, in order to avoid vulcanization when blind plate at occur it is unvulcanized existing
As vulcanization blind plate being developed, for example, the Chinese patent application No. is 201520507615.3 discloses a kind of Large Diameter Pipeline work
Cheng Guandao vulcanizes blind plate, and including blind plate plate body and mounting flange, the mounting flange is integrally formed at blind plate plate body periphery, institute
It states circumference uniform distribution on mounting flange and is provided with through-hole, the shape of the blind plate plate body is tablet, taper, spherical, ellipsoid is crown,
One kind in paraboloidal, and vulcanization ring is fixedly installed on the inside of through-hole on mounting flange, in sulfidation, even if passing through sulphur
Change the support of ring, the space that steam enters is provided between rubber slab and blind plate, but the steam at blind plate is less, temperature is still
Less than the temperature in pipeline, the vulcanization effect still unobvious at blind plate, secondly in sulfidation, only vulcanization squeezes rubber
Plate, the leakproofness at blind plate is poor, and the rubber slab in sulfidation at flange-interface is not affected by the extruding of blind plate, vulcanization pressure
Power is smaller, and rubber slab and inner wall of the pipe are bonded defective tightness during vulcanization, are susceptible to bubble, the compactness of rubber slab after vulcanization
It is poor.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of vulcanization blind plate for vacuum equipment, can solve
The problem of certainly prior art vulcanization effect is poor.
The utility model is achieved by the following technical programs.
A kind of vulcanization blind plate for vacuum equipment provided by the utility model, including blind plate, the shape of the blind plate is
Round tablet, and blind plate is connected by the flange-interface of bolt and pipeline, and rubber slab is equipped at insides of pipes and flange-interface,
It is characterized in that：Heating ring is further included, the heating ring is mounted on blind plate top by bolt, multiple heating are equipped in heating ring
The top of blind plate is tightly attached in device, the lower part of the heater.
The heating ring further includes housing, and the heater is mounted in the cavity of case inside, and passes through spring and shell
Body connects.
This vulcanization blind plate further includes temperature sensor, and the temperature sensor is installed on the shell, and temperature sensor
Induction end is tightly attached to the top of blind plate.
The housing is equipped with 4 mounting holes.
The housing with spring junction, equipped with protrusion.
The heater top is equipped with limited block.
The heater is electric heater.
The beneficial effects of the utility model are：It, can when pipeline vulcanizes by the setting heating ring on the outside of vulcanization blind plate
To heat the rubber slab at blind plate, improve the sulphur effect of rubber slab, rubber slab is squeezed by blind plate during vulcanization, after vulcanization with
Pipe flange fitting is close, and the compactness of rubber slab is high after vulcanization, and bubble is less, effectively raises vulcanized quality.

Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1 and Figure 2, a kind of vulcanization blind plate for vacuum equipment, including blind plate 1, the shape of the blind plate 1 is
Round tablet, and blind plate 1 is connect by bolt with the flange-interface of pipeline 3, and rubber slab is equipped at 3 inside of pipeline and flange-interface
4, it is characterised in that：Heating ring 2 is further included, the heating ring 2 is mounted on 1 top of blind plate by bolt, eight are equipped in heating ring 2
The top of blind plate 1 is tightly attached in a heater 5, the lower part of the heater 5, when pipeline carries out sulphur, due to close at blind plate 1
Envelope, steam circulation is not smooth, and since blind plate 1 is tightly attached on rubber slab 4, steam can not be heated, therefore is needed in vulcanization
Blind plate 1 is heated using heating ring 2, its temperature is made to reach the sulphur temperature of rubber slab 4, during vulcanization, is heated in ring 2
Heater 5 is tightly attached to 1 top of blind plate by the extruding of spring 7, its underpart, since blind plate 1 is metal material, good heat conductivity,
The generated thermal energy of heater 5 is transmitted to by blind plate 1 on rubber slab 4, and after the curing temperature requirement for reaching rubber, rubber is opened
Begin to carry out sulphur, heater 5 shares 8, and each heater has individual temperature sensor to be monitored, and makes on blind plate 1
Temperature everywhere keep unified, improve vulcanization effect, since rubber slab 4 is by the extruding of blind plate 1 during vulcanization, make itself and pipeline
3 flange fitting is closer, and the compactness of rubber slab 4 is high after vulcanization, and bubble is less, effectively raises vulcanized quality.
The heating ring 2 further includes housing 6, and the heater 5 is mounted in the cavity of 6 inside of housing, and passes through spring 7
It is connect with housing 6, heater 5 can slide on the vertical direction in the cavity of the inside of housing 6, using can be tightly attached to blind plate
On 1, the efficiency of heat transfer is improved.
This vulcanization blind plate further includes temperature sensor 8, and the temperature sensor 8 is mounted on shell 6, and temperature sensor
8 induction end is tightly attached to the top of blind plate 1, and temperature value is passed to control by temperature sensor 8 by detecting the temperature of blind plate 1
Device processed, controller constantly adjust the temperature of heater 5, the temperature of heater 5 are made to meet according to rubber slab 4 to sulphur according to temperature value
Change the requirement of temperature, and each heater 5 is independently arranged temperature sensor 8, avoids the occurrence of temperature deviation, influences vulcanization effect.
The housing 6 is equipped with 4 mounting holes 11, is fixed on blind plate by mounting hole 11 by ring 2 is heated during use, sulphur
Change introduce after, only need to remove 4 can bolt can remove heating ring 2, improve working efficiency, remove heating ring 2 after, blind plate 1 after
Continuous fixation and flange, play the role of sealing pipeline, and heating ring 2 can recycle.
The housing 6 with 7 junction of spring, equipped with protrusion 9, spring 7 is sleeved on protrusion 9, can prevent from making
With process be hit by a bullet spring shift.
5 top of heater is equipped with limited block 10, and limited block 10 can prevent heater 5 from being skidded off from housing 6.
The heater 5 is electric heater, since heating 2 internal structural space of ring is smaller, and needs to be bonded blind plate 1, electricity
The mode of heating can meet above-mentioned requirement, and the auxiliary line that electrical heating needs is less, can reduce equipment investment.
