Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
Existing disposal route is: operator blocks water to the injection direction of oneself with hand or other objects, but can not avoid completely by own and around personnel's clothing spatter with water, even sometimes, splash in people's eyes, when closing and opening this means of deflation, also to regulate monkey wrench, operate very inconveniently, and easily cause security incident.
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides a kind of hydraulic pressure test fixture general means of deflation, controls the injection direction of water, avoid that The water splash in all directions, and while closing means of deflation, without using spanner, make operating personnel easy to operate, safe and reliable.
Wherein, Novel air escaper structure is as shown in Fig. 2,3,4,5, wherein, mainly by bleed screw 1, venting nut 2, formed, wherein, specifically, as shown in Figure 6,7, the head of described bleed screw 1 is processed with the first sealing cone 11, and bottom is provided with rectangular tang portion 12, due to the circular milling for processing hexagonal of the prior art is become to flat, moment of torsion while twisting with hand to increase, without using spanner, handled easily personnel.
In addition, on described venting nut 2, be also processed with the second sealing cone 24 matching with described the first sealing cone, its tapering, with the conical surface of described the first sealing cone, uses two conical surface seals, its snap-in force, much smaller than the snap-in force with common plug screw sealing, has facilitated manual operations.
Further, preferably, on described venting nut 2, be also processed with the die cavity 22 of placing pore 21, traverse pore 23 vertically and being connected two vent holes, because traverse pore has been controlled the injection direction of water, avoided water to spray to surrounding.
When installing, described venting nut 2 is arranged on the upper cover plate below of hydraulic pressure test fixture, and is lined with rubber gasket, and described bleed screw 1 is positioned at top, upper cover plate below, and leaves gap between the first sealing cone and the second sealing cone.
In sealing, described venting nut 2 is arranged on the upper cover plate below of hydraulic pressure test fixture, and being lined with rubber gasket, described bleed screw 1 is positioned at top, upper cover plate below, and the conical surface between the first sealing cone and the second sealing cone fits tightly together.
Further, preferably, at the place, aperture of described traverse pore, place cotton or the cloth of blocking pore.
After the utility model has been taked such scheme, owing to being provided with the tang portion processing on bleed screw, having facilitated, use hand direct control, without re-using spanner; And, in addition.
Principle of work is as follows:
First with spanner, venting nut 2 is arranged on the upper cover plate of hydraulic pressure test fixture, and the upper suitable rubber gasket of pad, the bleed screw 1 of screwing on, make to leave gap between two sealing cones, now this means of deflation is in opening, to in housing chamber during water filling, the gas in chamber first enters in little die cavity through the pore of placing vertically of venting nut 3, then is discharged by traverse pore.When traverse pore has water ejection, illustrate that housing intracavity gas is drained, now hand-tight make-up bleed screw 1, makes two sealing cone laminatings, and now this means of deflation is in sealing state, and the endoceliac water of shell is completely sealed, and starts to do the hydraulic testing.The hydraulic testing to be finished, removes hydraulic pressure test fixture.
In doing hydraulic testing process, operator can stand in the opposite location of traverse pore, avoids water to spray to oneself, also can place the soft fabrics such as cotton, cloth at place, traverse pore aperture, far away to prevent that water from spraying.
Effect of the present utility model is as follows:
1 is simple in structure, and usable range is wide, and common hydraulic pressure test fixture all can be used this means of deflation, can promote solution Similar Problems.
2 is easy to operate, and sealing effectiveness is reliable, and the tang portion especially processing on bleed screw, without re-using spanner, has facilitated operation, has saved the running time, has improved production efficiency.
3 make simply, with low cost, safe and reliable.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
