Abstract
The utility model relates to a barrel connecting pipe pressure test plugging device. The barrel connecting pipe pressure test plugging device comprises a barrel body, a connecting pipe, a cover plate, a fixing plate and a pull rod. The side wall of the barrel body is communicated with the connecting pipe in the radial direction, the opening in the upper end of the connecting pipe is located outside the barrel body and coaxially covers the cover plate, the opening in the lower end of the connecting pipe is located inside the barrel body and coaxially presses the fixing plate, the inverted pull rod coaxially penetrates through the fixing plate and the cover plate, and the cover plate is pressed in the opening in the upper end of the connecting pipe through a nut matched with the pull rod. The opening in the upper end of the connecting pipe is completely sealed through the cover plate, the fixing plate and the pull rod, the sealing bulge test of equipment is convenient to conduct, all components can be directly taken down after the test, the end of the connecting pipe does not need to be processed, and test cost is effectively saved. The upper end face and the lower end face of the cover plate are respectively provided with a sealing piece, and therefore the sealing performance of the equipment in the testing process is effectively guaranteed. The barrel connecting pipe pressure test plugging device is simple in structure, scientific and reasonable in design and capable of effectively reducing test cost and improving work efficiency.
Description
Technical field
The utility model belongs to testing installation technical field, specifically, is a kind of barrel connecting pipe expanding blocking device of pressure test.
Background technique
After the device fabrication such as boiler, pressurized container completes, technician, for the sealability of testing apparatus, need to carry out bulge test to the sealing of equipment, needs at the trial all equipment adapter sealings.
Traditional adapter encapsulating method is to take over reserved process section, ensures to seal with closure plate with taking over welding, needs to adopt Methods of OFC-A to prescind process section and closure plate after test, also need by adapter port polish, groove opening.
Not only operational sequence is loaded down with trivial details to adopt said method, and wasting manpower and material resources, and working efficiency is low.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of barrel connecting pipe expanding blocking device of pressure test is provided, and this device is detachable, reusable, not only reduces costs, and increases work efficiency.
Technical solutions of the utility model are achieved in that
A kind of barrel connecting pipe expanding blocking device of pressure test, comprise cylindrical shell, adapter, cover plate, fixed plate and pull bar, the sidewall radial communication of described cylindrical shell is taken over, the upper end open of this adapter is positioned at cylindrical shell outside and coaxially mounts cover cover plate, this adapter lower ending opening is positioned at inner barrel and coaxially press-fits fixed plate, described fixed plate and cover plate coaxially install the pull bar arranging that stands upside down, and by the nut coordinating with pull bar, cover plate are fitted in to the upper end open portion that takes over.
And the pull bar of described cover plate top is coaxially installed gland, coaxial installation O-ring seal between this gland and cover plate; Between described cover plate and adapter upper end open, co-axial seal is installed gasket seal.
And the upper-end surface of described cover plate is upwards extended one and is shaped with the upper annular groove that holds described O-ring seal, the lower end surface of this cover plate is shaped with and holds the lower annular groove of taking over upper end open to downward-extension one.
Advantage of the present utility model and good effect are:
This device seals the upper end open portion of adapter completely by cover plate, fixed plate and pull bar, facilitates the seal and bulge test of equipment, directly each part is taken off, and process without butt tube port again after test, effectively saves experimentation cost; By the upper and lower end face at cover plate, Sealing is installed respectively, has effectively been ensured sealability when equipment is tested.The utility model is simple in structure, design science is reasonable, effectively reduces experimentation cost, has improved working efficiency.
Brief description of the drawings
Fig. 1 is structure sectional view of the present utility model;
Fig. 2 is the structure sectional view of the utility model cover plate.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of barrel connecting pipe expanding blocking device of pressure test, as shown in Figure 1, comprise cylindrical shell 5, adapter 4, cover plate 2, fixed plate 6 and pull bar 9, the sidewall radial communication of described cylindrical shell is taken over, the upper end open of this adapter is positioned at cylindrical shell outside and coaxially mounts cover cover plate, this adapter lower ending opening is positioned at inner barrel and coaxially press-fits fixed plate, and described fixed plate and cover plate coaxially install the pull bar arranging that stands upside down, and by the nut 8 coordinating with pull bar, cover plate is fitted in to the upper end open portion that takes over.
In the present embodiment, for ensure cover plate and take between sealability, the pull bar of described cover plate top is coaxially installed gland 1, coaxial installation O-ring seal 7 between this gland and cover plate; Between described cover plate lower end surface and adapter upper end open, co-axial seal is installed gasket seal 3.
The upper-end surface of described cover plate is upwards extended one and is shaped with the upper annular groove 10 that holds described O-ring seal, and as shown in Figure 2, the lower end surface of this cover plate is shaped with and holds the lower annular groove 11 of taking over upper end open to downward-extension one.
This device seals the upper end open portion of adapter completely by cover plate, fixed plate and pull bar, facilitates the seal and bulge test of equipment, directly each part is taken off, and process without butt tube port again after test, effectively saves experimentation cost; By the upper and lower end face at cover plate, Sealing is installed respectively, has effectively been ensured sealability when equipment is tested.The utility model is simple in structure, design science is reasonable, effectively reduces experimentation cost, has improved working efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
