Abstract
The assembly is composed of body case, seal ring, sealing flange, stretchable rubber bag, ring of clamping collar and clamping collar. Being setup inside the body case, the stretchable rubber bag with open end is toward outside. One end of the bag is in closed integrative form, and another end of the bag is in flanging plane form. The ring of clamping collar and clamping collar are setup on inner side cylindroid of the said flanging plane. Inner annular plane of the sealing flange impacts flanging plane of the bag so as to form a sealing surface. Comparing with prior art, the invention omits seal structure in one end in order to reduce probability of oil leakage. Seal structure in impacted flanging plane, which is easy to be installed, is adopted in another end instead of spring steel wire ring so as to avoid oil leakage caused by fatigue deformation of spring steel wire ring and aging cracks of rubber.
Description
Technical field
The present invention relates to the insulating element that radiographic source uses, relate to a kind of x-ray source insulation oil expansion part in more detail.
Background technology
The swelling part of oil immersed type of the prior art insulation x-ray source mainly contains two kinds of forms, a kind of bellows form of making for Metal Material Welding, and the major defect of this kind swelling part is: manufacture difficulty is big, the cost height; The cavity volume that forms is little, and the dilatation amount causes the trapped fuel amount few for a short time.In the prior art, also have a kind of flexible capsule form of rubber that is, the fastening means of generally taking is that two ends are ring flange, and the two-port of the flexible capsule of rubber is inserted in the holddown groove of ring flange, and is fastening with wire loop and screw that spring steel wire is made.The major defect of this kind swelling part is: oil seepage phenomena occurs at flange sealing surface place, swelling part two ends easily.Why produce oil seepage phenomena, its main cause: the one, spring steel wire coil is in for a long time and produces tiredly in the variation of tensile stress and ambient temperature, and length changes; The 2nd, the flexible capsule mouth director of rubber is in the shear stress of spring steel wire coil, the variation of ambient temperature, the immersion of insulating oil the phase, causes ageing of rubber, cracks even ruptures.The generation of this kind phenomenon all will cause the damage of x-ray source and operational environment will be polluted.
Summary of the invention
The object of the present invention is to provide a kind of brand-new x-ray source insulation oil expansion part, described x-ray source can thoroughly solve defectives such as the existing x-ray source existing easy generation seepage oil of swelling part, cost height, inconvenient maintenance, contaminated environment with insulation oil expansion part.
Technical solution of the present invention is: the x-ray source that is connected on the x-ray source casing mainly is made up of parts such as housing, sealing ring, sealing flange, flexible capsule, pressure ring circle, pressure rings with insulation oil expansion part.Wherein, flexible capsule is arranged in the housing, and its opening is outside, and described flexible capsule is a rubber, makes an end and is sealing one form, and the other end is the flange plane form, is beneficial to form when assembling sealing surfaces.Pressure ring circle and pressure ring are successively set on the inboard cylindroid in flexible capsule flange plane, and sealing flange interior annular plane is pressed on the flexible capsule flange plane and forms sealing surface, and is screwed on the x-ray source casing.The inner chamber of flexible capsule of the present invention fills with high voltage insulating oil, to play the insulating effect to the radiation of X ray.Use when of the present invention, described x-ray source is fixed on the x-ray source casing with the housing of insulation oil expansion part gets final product.
The invention has the beneficial effects as follows:
1. flexible capsule of the present invention is compared with flexible capsule of the prior art, has removed the hermetically-sealed construction of an end, has reduced seepage oil probability; The other end adopts the plane to press the form hermetically-sealed construction, and simple installation is reliable, has effectively prevented the oil seepage phenomena that the reasons such as fatigue deformation, ageing of rubber crack fracture owing to spring steel wire coil cause.
2. flexible capsule of the present invention is simple in structure, thereby manufacturing cost is lower.
3. the present invention is because designs simplification is so installation and maintenance are all more convenient, easy and simple to handle reliable.

Embodiment
Now introduce the specific embodiment of the present invention in detail in conjunction with Figure of description.At first sealing ring 1 is put into the cannelure of sealing flange 2, sealing flange 2 is fixed on the relevant position of x-ray source casing 8, play being tightly connected between sealing flange 2 and the x-ray source casing 8 with soket head cap screw 9; Sealing flange 2 interior annular planes are pressed on the flexible capsule 5 flange planes and form sealing surface, and pressure ring circle 3 is arranged on the medial surface of the ring surface of flexible capsule 5 opening portions, and pressure ring 4 is pressed against on the pressure ring circle 3.In assembling process, pressure ring 4 is tightened fixing, make be tightly connected between sealing flange 2 and the flexible capsule 5 solid and reliable.The inner chamber of flexible capsule 5 fills with high voltage insulating oil 10, to play insulating effect.
The effect of the pressure ring circle 3 that the present invention is set is: if there is not pressure ring circle 3, flexible capsule 5 compresses pressure ring 4 directly contact in fastening process, the frictional force of seal face is very big, be difficult for judging whether pressure ring 4 is in place, and behind the pressure ring circle 3 of packing between the seal face of flexible capsule 5 and the pressure ring 4, frictional force between the seal face reduces, and can effectively guarantee the sealing of installing.
Housing 6 of the present invention is sleeved on the outside of flexible capsule 5, and uses bolt 7 that housing 6 and x-ray source casing 8 are fixed together, and plays the effect of the flexible capsule 5 of protection.
The invention is not restricted to the foregoing description, for the professional in present technique field, any improvement that the embodiment of the invention is made or change can not exceed the protection range of design of the present invention and claims.
