Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.
As shown in Figures 1 to 4, the invention provides a kind of seal arrangement for test lead fitting seat, comprise sealing seat pedestal 10, pressure-bearing orifice plate 12, attaching nut 9, sealing orifice plate 8 and gland nut 7.
Cylindrically, endoporus has cavity to sealing seat pedestal 10.
Pressure-bearing orifice plate 12 sealing is arranged on the end, one end of sealing seat pedestal 10, and the inside of pressure-bearing orifice plate 12 axially offers multiple cone shape hole along sealing seat pedestal 10.Wherein, pressure-bearing orifice plate 12 and sealing seat pedestal 10 end can seal in a number of suitable ways, in the present embodiment, can be provided with gasket seal 11 between sealing seat pedestal 10 and pressure-bearing orifice plate 12.
Attaching nut 9 is set on sealing seat pedestal 10 outer ring surface, for sealing seat pedestal 10 and pressure-bearing orifice plate 12 are sealed the test lead fitting seat be fixed on combustion box together.For being fixedly connected with the outside thread of nut 9 on combustion box, attaching nut 9 is provided with the internal thread matched with it near one end of combustion box, be fixedly connected with by screw thread.
The sealing of sealing orifice plate 8 is fixed on the other end end of sealing seat pedestal 10, and on sealing orifice plate 8, corresponding position offers multiple cone shape hole, and tapered bore profile is identical with the tapered bore profile of pressure-bearing orifice plate 12.Wherein, the setting that orifice plate 8 and the upper conical hole number of pressure-bearing orifice plate 12 and shape can carry out being applicable to as required is sealed; In the present embodiment, cone shape hole quantity is identical with the test lead quantity of required extraction, and cone shape hole cone angle is 5 ~ 10 °, and diameter is 1 ~ 4mm; In addition, the centre distance between any two cone shape holes should be greater than 1.5 times of cone shape hole diameter, to ensure the integrally-built stability of sealing orifice plate 8.
Gland nut 7 is for being fixed on the end of sealing seat pedestal 10 by the sealing of sealing orifice plate 8.Can offer at sealing seat pedestal 10 outside thread matched with gland nut 7 on one end outer ring surface of gland nut 7, be fixedly connected with by screw thread.
Seal arrangement for test lead fitting seat of the present invention, structure is simple, highly versatile, reliable performance; By cone shape hole multiple on pressure-bearing orifice plate 12, arrange separating between every root test lead, thus increase sealability when it is installed, at effective sealing under high-temperature and high-pressure conditions, high pressure gas leakage can be prevented.In addition, by pressure-bearing orifice plate 12 and sealing orifice plate 8, sealing seat pedestal endoporus is separated, can the stability of enhanced leaktightness seat pedestal endoporus sealer, prevent sealer from being dispelled by high pressure draught, and the glue of various states can be filled in sealing seat pedestal endoporus, applicability is stronger.
In seal arrangement for test lead fitting seat of the present invention, in order to further by sealing stability, an end face of the close test lead fitting seat of pressure-bearing orifice plate 12 is provided with sealed rubber plate 13, on sealed rubber plate 13 corresponding position offer multiple cone shape hole identical from pressure-bearing orifice plate 12 (can be different with the concrete structure of the cone shape hole of pressure-bearing orifice plate 12, can be common through hole), and diameter should be slightly less than test lead diameter, to utilize the elasticity banding test lead of rubber, prevent sealer in encapsulating cavity from exosmosing.
When the cone shape hole that test lead passes sealed rubber plate 13 and pressure-bearing orifice plate 12 enters into sealing base 10 inside, the end face of sealing base 10 near test lead fitting seat seals by sealed rubber plate 13, pressure-bearing orifice plate 12 and gasket seal 11, and sealing base 10 inside forms the cavity of antiseepage.
When seal arrangement for test lead fitting seat of the present invention is installed, first the test lead of drawing in casing pedestal is passed the cone shape hole of sealed rubber plate 13 and the cone shape hole of pressure-bearing orifice plate 12, each perforate, through 1 lead-in wire, then passes sealing base 10 internal cavities.Gasket seal 11 is added to ensure the sealing effect of sealing base 10 mounting edge position between sealing base 10 and pressure-bearing orifice plate 12, then by attaching nut 9, said modules is connected with casing mounting base, thus obtains the cavity structure airtight near casing mounting base side.
Then, by the test lead through sealing base 10 through each cone shape hole of sealing orifice plate 8, to limit wire locations completely.By sealed rubber plate 13, pressure-bearing orifice plate 12, gasket seal 11, after the semi-solid or liquid high-temperature seal adhesive of the empty intra-bladder instillation that sealing base 10 forms (in prior art, owing to there is no the axial fixing structure effect of cone shape hole, semifixed glue can only be filled), to seal orifice plate 8 shutoff sealing base 10 and with gland nut 7 pressing sealing structure, namely to complete the sealing of lead-in wire fitting seat after glue to be sealed solidifies completely.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
