Abstract
The utility model relates to a sealing clamping device used in pressure strength tests of a high-pressure control valve. Two O-shaped sealing rings are placed in two grooves disposed on the small cylinder of a sealing pressing cover. A sealing steel ball is placed in a threaded hole on the sealing pressing cover. An adjusting forcing screw equipped with a gasket is in threaded connection with the threaded hole on the sealing pressing cover. A sealing pressing sleeve is buckled on the sealing pressing cover. A plurality of forcing screws provided with gaskets pass through the threaded holes on a sealing pressing sleeve, respectively. The sealing clamping device has characteristics of a small size, compact structure, low production cost, and convenience and practicality. Pressure strength tests of high-pressure straight and corner control valves with multiple specifications and pressure ratings can be achieved by replacing sealing pressing sleeves and sealing pressing covers with different calibers.
Description
Technical field
The utility model relates to a kind of high pressure control valve verification sealing clamp, particularly a kind of sealing clamp of high pressure control valve compressive resistance test use.
Background technology
The sealing clamp of traditional high pressure control valve compressive resistance test use, its sealing gland as shown in Figure 3, adopt real stem seal part, when test pressure increases, pressurized air in tested operation valve cavity can't be discharged smoothly, pressure medium in tested operation valve cavity can't be increased, cause the test of high-pressure control valve to be difficult to carry out smoothly.
Summary of the invention
In view of problems of the prior art, the utility model provides a kind of sealing clamp of high pressure control valve compressive resistance test use, this device adopts inside and outside double sealing structure, increased the venthole setting, when test pressure increases, can produce pressurized air in tested operation valve cavity, at this moment can regulate the adjusting housing screw arranged in sealing gland by unclamping, all gas in chamber is discharged, after will regulate housing screw and tighten, pressure medium in cavity is increased sharply, can make the compressive resistance test of high-pressure control valve carry out smoothly.
[0004]the utility model for achieving the above object, the technical scheme adopted is: a kind of sealing clamp of high pressure control valve compressive resistance test use, comprise sealed pressing sleeve, sealing gland, O-ring seals, housing screw, the first pad, it is characterized in that: also comprise the adjusting housing screw, the second pad, sealed steel ball, two different right cylinders that described sealing gland is structure as a whole form, be provided with circle first groove two cylindrical joints of difference, be provided with a circle opening groove at the edge of large cylinder bottom surface, on large cylinder, circle centre position is provided with screw, in the small cylinder bottom surface, circle centre position is provided with venthole, the screw of large cylinder communicates with the venthole of small cylinder by aperture, two described O-ring seals are placed in respectively in two the second grooves that the sealing gland small cylinder is provided with, described sealed steel ball is placed in the screw of sealing gland, being installed with the described adjusting housing screw of the second pad and the screw of sealing gland is spirally connected, described sealed pressing sleeve spiral-lock is on sealing gland, and the several described housing screw that is installed with the first pad penetrates respectively in the screw on sealed pressing sleeve.
Characteristics of the present utility model are: when doing the compressive resistance test, when test pressure increases, air in tested operation valve cavity, can be by regulating just Exhaust Gas smoothly of the adjusting housing screw that arranges in sealing gland, after will regulate housing screw and tighten the verification sealing demand that realizes high-pressure control valve, just can complete that high pressure is straight-through, the angular form control valve compressive resistance is tested.
This device volume is little, compact conformation, low cost of manufacture, convenient and practical.Can realize that the high pressure of many specifications, multiple pressure power grade leads directly to, the compressive resistance test of angle control valve door by sealed pressing sleeve, the sealing gland of changing different bores.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The A-A enlarged drawing that Fig. 2 is Fig. 1;
Fig. 3 is the straight-through verification sealing gland schematic diagram of traditional high pressure;
Fig. 4 is high pressure verification sealing gland schematic diagram of the present utility model.
Embodiment
Below in conjunction with figure mono-embodiment, the utility model is described further.
As Fig. 1, 2, shown in 4, the sealing clamp of high pressure control valve compressive resistance test use, comprise sealed pressing sleeve 1, sealing gland 2, O-ring seals 3, housing screw 7, the first pad 8, also comprise and regulate housing screw 4, the second pad 5, sealed steel ball 6, two different right cylinders that sealing gland 2 is structure as a whole form, be provided with circle first a groove 2-1 two cylindrical joints of difference, be provided with a circle opening groove 2-2 at the edge of large cylinder bottom surface, on large cylinder, circle centre position is provided with screw 2-3, in the small cylinder bottom surface, circle centre position is provided with venthole 2-4, the screw 2-3 of large cylinder communicates with the venthole 2-4 of small cylinder by aperture.Two O-ring seals 3 are placed in respectively in two the second groove 2-5 that sealing gland 2 small cylinders are provided with, sealing gland 2 is pressed onto on tested high pressure control valve part 9, sealed steel ball 6 is placed in to the screw 2-3 of sealing gland 2, the adjusting housing screw 4 that is installed with the second pad 5 is screwed together with the screw 2-3 of sealing gland 2, and sealed pressing sleeve 1 spiral-lock is fixed on tested high pressure control valve part 9 by several housing screws 7 that are installed with the first pad 8 on sealing gland 2.The effect that designs the first groove 2-1 is, when sealing gland 2 spiral-locks are on tested high pressure control valve part 9, the aperture of tested high pressure control valve part 9 is in the position of the first groove 2-1, can make like this sealing gland 2 and tested high pressure control valve part 9 friction tight better.The purpose of design opening groove 2-2 is that, after test completes, tool using can be by the convenient taking-up of sealing gland 2 by opening groove 2-2.Design the purpose of pore 2-4: the one, be convenient to discharge the pressurized air in tested high voltage control valve chamber, the 2nd, only need very little power just can, by regulating housing screw press seal steel ball, guarantee sealing.
