Abstract
The invention discloses a sealing device for pressure testing. The sealing device is used for sealing a pressure product for pressure testing. The sealing device is characterized by comprising a sealing cover plate and an assistance sealing clamp. The sealing cover plate is pressed on the pressure product, and the pressure product is provided with an axial sealing groove and is sealed by a rubber O-shaped ring in the axial sealing groove. The assistance sealing clamp clings to the circumference of the pressure product, is fixed on the sealing cover plate and covers a gap between the pressure product and the sealing cover plate. The sealing device for pressure testing is simple to manufacture, lower in cost, fine in sealing effect and particularly applicable to pressure testing of high-pressure products.
Description
Technical field
The present invention relates to a kind of pressure test seal arrangement.
Background technique
When doing pressure vessel blasting test, need to seal pressure product, if seal ring is subject in the product die cavity its axial pressure and unable when seal ring and seal groove are closely cooperated, seal ring will stressedly eject from the slit of product and sealed cover, the gas leakage of generation slit makes the pressure test failure.
Summary of the invention
The object of the invention is to provide a kind of sealing effect good for defects, prevents the pressure test seal arrangement of seal ring gas leakage.
The present invention adopts following technological scheme for achieving the above object:
A kind of pressure test seal arrangement, be used for the sealing load product and carry out pressure test, it is characterized in that: it comprises sealed cover and auxiliary seal anchor clamps, and described sealed cover is pressed on the pressure product, described pressure product is provided with the axial seal groove, by being arranged on the rubber o-ring sealing in the groove; Described auxiliary seal anchor clamps are close on the periphery of pressure product, are fixed on the described sealed cover, cover in the slit between pressure product and the sealed cover.
It is further characterized in that: be connected and fixed by screw rod between described pressure product and the sealed cover.
Further: described auxiliary seal anchor clamps are four, are evenly distributed on the sealed cover, are bolted on the described sealed cover.
The present invention makes simply, and cost is lower, and good sealing effect is applicable to the pressure test of the higher pressure product of pressure by it.
Description of drawings
Fig. 1 is schematic representation of the present invention;
Fig. 2 is the present invention and pressure product connection diagram;
Fig. 3 is that auxiliary seal anchor clamps of the present invention connect partial enlarged drawing.
Embodiment
A kind of pressure test seal arrangement as shown in Figure 1, be used for the sealing load product and carry out pressure test, it comprises sealed cover 2 and auxiliary seal anchor clamps 3, described sealed cover 2 is pressed on the pressure product 1, described pressure product 1 is provided with the axial seal groove, by being arranged on the rubber o-ring sealing in the groove; Described auxiliary seal anchor clamps 3 are close on the periphery of pressure product 1, are fixed on the described sealed cover 2, cover in the slit between pressure product 1 and the sealed cover 2.
Be connected and fixed by screw rod between described pressure product 1 and the sealed cover 2.Described auxiliary seal anchor clamps 3 are four, are evenly distributed on the sealed cover 2, are bolted on the described sealed cover 2.
First sealed cover is pressed on the pressure product during use, fixes by screw rod, then successively the auxiliary seal anchor clamps are fixed on the sealed cover, the slit between pressure product and the sealed cover is covered in.
