Abstract

The utility model relates to a blind plate, in particular to the blind plate used for detecting of valve pressure testing. The blind plate comprises a blind plate body. A plurality of connecting pieces are arranged on the outer edge of the blind plate body along the circumference. A ventilation bolt and a liquid inlet bolt are arranged on the outer end face of the blind plate body. A groove is arranged in the middle of the inner end face of the blind plate body. A high-pressure self-sealing ring is arranged in the groove, and a V-shaped groove is formed in the inner side surface of the high-pressure self-sealing ring. The outer end face of the high-pressure self-sealing ring in the groove is slightly higher than the inner end face of the blind plate body. The blind plate is simple in structure, reasonable in design, convenient to install and use, free from large tightening force when being used, and good in sealing effects.

Description

A kind of blind plate

Technical field:

The utility model relates to a kind of blind plate, especially a kind of blind plate that is used for valve pressure testing detection usefulness.

Background technique:

To lead to highly pressurised liquid after the valve processing and assembling is good and carry out pressure testing and detect, guarantee that 10 minutes internal pressures do not fall, just qualified.With blind plate the valve two ends are sealed during pressure testing, at present, adopt the O RunddichtringO between blind plate and the valve, seal by blind plate and valve end extruding O RunddichtringO, when passing to highly pressurised liquid in the valve body, not reveal in order to guarantee highly pressurised liquid, the moment of torsion of tightening the bolt needs that connect blind plate and valve two end part is very big, usually need just can finish with large-scale torque wrench, the assurance test medium is not revealed.Present O RunddichtringO just plays buffer action at the bus place of round column structure, and the problem of leakage is still bigger.

The model utility content:

The utility model provides a kind of blind plate, and it is simple in structure, and is reasonable in design, easy to install, need not very big screwing force during use, and good sealing effect, can solve problems of the prior art.

The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: it comprises a blind plate body, outer rim at the blind plate body is provided with some links along circumference, on the exterior edge face of blind plate body, be provided with ventilation bolt and feed liquor bolt, interior edge face middle part at the blind plate body is provided with a groove, be provided with the high pressure selfsealings circle of an inner surface band V-shaped groove in the groove, the described interior edge face that is located at the exterior edge face of the high pressure selfsealings circle in the groove a little more than the blind plate body.

Two end surfaces of described high pressure selfsealings circle form the conical surface.

The utility model is simple in structure, reasonable in design, easy to install, interior edge face middle part at the blind plate body is provided with a groove, be provided with the high pressure selfsealings circle of an inner surface band V-shaped groove in the groove, the described interior edge face that is located at the exterior edge face of the high pressure selfsealings circle in the groove a little more than the blind plate body, two end surfaces of described high pressure selfsealings circle form the conical surface, in use, blind plate is initially tightened with the gate valve two ends and is just produced certain pretightening force when being connected, and test medium pressure is big more, interior pressure axially, under the radial compression applied, high pressure selfsealings circle contacts tightr with the blind plate body, and surface of contact is also bigger, be difficult for revealing, need not just can reach good sealing effect by very big screwing force.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Among the figure, 1, the blind plate body, 2, link, 3, the ventilation bolt, 4, the feed liquor bolt, 5, groove, 6, high pressure selfsealings circle, 7, V-shaped groove.

Embodiment:

For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in FIG., the utility model comprises a blind plate body 1, outer rim at blind plate body 1 is provided with some links 2 along circumference, on the exterior edge face of blind plate body 1, be provided with ventilation bolt 3 and feed liquor bolt 4, interior edge face middle part at blind plate body 1 is provided with a groove 5, be provided with the high pressure selfsealings circle 6 of an inner surface band V-shaped groove 7 in the groove 5, be located at the interior edge face of the exterior edge face of the high pressure selfsealings circle 6 in the groove 5 a little more than blind plate body 1.

The utility model is simple in structure, reasonable in design, easy to install, interior edge face middle part at blind plate body 1 is provided with a groove 5, be provided with the high pressure selfsealings circle 6 of an inner surface band V-shaped groove 7 in the groove 5, be located at the interior edge face of the exterior edge face of the high pressure selfsealings circle 6 in the groove 5 a little more than blind plate body 1, two end surfaces of high pressure selfsealings circle 6 form the conical surface, in use, blind plate is initially tightened with the gate valve two ends and is just produced certain pretightening force when being connected, and test medium pressure is big more, interior pressure axially, under the radial compression applied, high pressure selfsealings circle 6 contacts tightr with blind plate body 1, and surface of contact is also bigger, be difficult for revealing, need not just can reach good sealing effect by very big screwing force.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.

Claims (2)

1. blind plate, comprise a blind plate body, outer rim at the blind plate body is provided with some links along circumference, on the exterior edge face of blind plate body, be provided with ventilation bolt and feed liquor bolt, it is characterized in that: the interior edge face middle part at the blind plate body is provided with a groove, be provided with the high pressure selfsealings circle of an inner surface band V-shaped groove in the groove, the described interior edge face that is located at the exterior edge face of the high pressure selfsealings circle in the groove a little more than the blind plate body.
