Description
Technical field
The utility model belongs to the liquid loading and unloading equipment technical field, specifically, relates to oil filling riser magnetic obturator.
Background technology
At present, domestic extensive employing oil filling riser is to slot train car or poisonous, the volatile liquid medium of transportation tank loading and unloading, because there is the volatilization phenomenon in most liquid dielectrics particularly light oil, in order to prevent the pollution of the environment, need seal the jar mouth when carrying out the loading and unloading of liquid dielectric.The jar mouthful diameter of existing train tank car or transportation tank differs, therefore adopt the cone seal nested structure to realize jar sealing of mouth usually, but in actual use, increase along with liquid dielectric in tank car or the tank car, by gravity jar mouth position will move down, cause cone-shaped sealed gland and jar mouthful between can not continue to keep closed contact, cone-shaped sealed gland can the gap occur between the inwall and cause leakage with a jar mouth.For the jar that solves train tank car or transportation tank mouthful seals insecure problem when the loading and unloading operation, the inventor in first to file a kind of oil filling riser with a jar mouthful obturator (publication number: CN200999141), this obturator employing setting-in on end socket magnetic shrouding is the magnet steel of circle distribution, by magnetic force end socket magnetic shrouding is adsorbed on jar mouth, and, between cover flange cover and end socket magnetic shrouding, the rubber rolling diaphragm is installed, is used for the displacement of compensating tank mouth.But in the middle of reality was used, there was damage easily in the rubber rolling diaphragm, and causes the still insecure problem of obturator sealing; Again because end socket magnetic shrouding is limited at the slide displacement that cover flange puts, and hose coupling is installed on the end socket magnetic shrouding and is used to install the external thread sleeve that liquid level warning is popped one's head in, it is dumb to cause end socket magnetic shrouding to slide, and therefore, causes the decline displacement of compensating tank mouth well of end socket magnetic shrouding.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of oil filling riser magnetic obturator, this obturator long service life, and the decline displacement of energy full remuneration jar mouth.
In order to address the above problem, the technical solution of the utility model is as follows: a kind of oil filling riser magnetic obturator, comprise magnetic shrouding and sleeve pipe, be installed with sleeve pipe in the centre hole of magnetic shrouding, on this magnetic shrouding, be embedded with the magnet steel that is circle distribution, on the described sleeve pipe above the described magnetic shrouding, be installed with upper sealing plate, this upper sealing plate is connected through wrinkle shape leather bag with described magnetic shrouding, this leather bag is sleeved on the described sleeve pipe, and described upper sealing plate is provided with oil gas and reclaims mouth, and this oil gas reclaims mouth and communicates with leather bag.
On sleeve pipe, be provided with fixing upper sealing plate and movable magnetic shrouding, upper sealing plate is connected through leather bag with movable magnetic shrouding, leather bag plays transmission medium gas and bit shift compensation effect, the magnetic shrouding is adsorbed on jar mouth by magnetic force, when the increase of liquid dielectric in train tank car or the transportation tank and a jar mouth when moving down, the magnetic shrouding can be along with moving down together, make the magnetic shrouding with jar mouthful between remain closely and reliably contact.Compared with prior art, leather bag has that flexible scope is big, wear-resistant, the advantage of long service life, and magnetic shrouding scope in axial sliding is bigger, and it is more flexible to slide, well the decline displacement of compensating tank mouth.
As preferably, be connected with the locating cone tube at the lower surface of magnetic shrouding, this locating cone tube covers on the described sleeve pipe, and the locating cone tube play the guiding role when sleeve pipe was inserted jar mouthful.
In described sleeve pipe, be provided with the probe straight tube, the upper end open of this probe straight tube is higher than described upper sealing plate, and be communicated with the fairlead that is located at described cover tube wall top, the lower ending opening of this probe straight tube is lower than described locating cone tube, is communicated with the inlet opening that is located at described cover tube wall bottom.Move in the sleeve pipe by the straight tube that will be used to install the liquid level warning probe, help making sealing device structure compacter, conserve space.
Be installed with bracing ring on the described sleeve pipe below the described magnetic shrouding, this bracing ring plays spacing effect to the magnetic shrouding.
Since leave the circulation of certain clearance supplied gas between the inwall of magnetic shrouding and the sleeve pipe, excessive in order to prevent the magnetic shrouding at the rotational angle that makes progress in week, between bracing ring and described upper sealing plate, be provided with and keep off pipe, the interior bearing fit of centre hole that this retaining pipe inserts described magnetic shrouding.
When the magnetic shrouding descends and the bracing ring rigid collision, between the lower end tapered wall of the male cone (strobilus masculinus) of described bracing ring and described magnetic shrouding centre hole, be provided with support ring.
The beneficial effects of the utility model are: the utility model is the decline displacement of compensating tank mouth in a big way, guarantees that Jar opening sealer is reliable, but also has the advantage of long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Further the utility model is illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, oil filling riser mainly is made of sleeve pipe 2, upper sealing plate 4, magnetic shrouding 1 and leather bag 5 with the magnetic obturator, fixed cover is equipped with upper sealing plate 4 on the top of sleeve pipe 2, and this upper sealing plate 4 is provided with oil gas and reclaims a mouthful 4a, and oil gas reclaims on mouthful 4a hose coupling 11 is installed.Kink has magnetic shrouding 1 in the bottom of sleeve pipe 2, is embedded with the magnet steel 3 that is circle distribution on the magnetic shrouding 1, and the lower surface of magnetic shrouding 1 is connected with locating cone tube 6, and this locating cone tube 6 is sleeved on the described sleeve pipe 2.Upper sealing plate 4 is connected through wrinkle shape leather bag 5 with magnetic shrouding 1, and leather bag 5 is contained on the sleeve pipe 2, and the upper end of leather bag 5 is installed in the lower surface of upper sealing plate 4 through top board 12, and the lower end of leather bag 5 is installed in the upper surface of magnetic shrouding 1 through lower platen 13.
