Description
Technical field
This utility model relates to pressure testing equipment field, especially a kind of blast furnace copper cooling stave hydraulic pressure pressure testing device.
Background technology
The cooling device that on blast furnace, bosh and furnace bosh section use is generally copper cooling wall, and copper cooling wall uses screw thread with water pipe
Screw thread mode connects.In construction, cooling wall is required for carrying out the water pressure test before installing, and generally uses O-shaped rubber ring or rubber
Glueballs utilizes the mode of extruding internal expanding to carry out cooling wall water pipe sealing pressure testing, but owing to the material of cooling wall water pipe is copper, pipe
Mouth has deformation during O-shaped rubber ring or ball extrude internal expanding, thus causes being difficult to during next step connecting water pipe connect,
Even do not connect.According to practical construction experience, the cooling wall water pipe of about 30% can normal mounting after need to processing
Water tubular union, has a strong impact on follow-up water tubular union installation progress, increases construction cost.
Utility model content
Technical problem to be solved in the utility model is: provide one the cooling wall water pipe mouth of pipe will not be made to deform and
The blast furnace copper cooling stave hydraulic pressure pressure testing device of good seal.
Be the technical scheme is that blast furnace copper cooling stave hydraulic pressure pressure testing fills by solving above-mentioned technical problem this utility model
Putting, after on cooling wall, all water pipes all connect sealing device, water inlet pipe is sequentially connected with water inlet ball valve and Pressure gauge, water inlet again
The external hydraulic test pump of ball valve, outlet pipe connects outlet ball valve, seals against each other connection between remaining cooling wall water pipe；Described sealing
Device lower end is for carrying female dome structure, and the top of dome structure is provided with sealing gasket, and sealing device is with all water pipes all
Threaded, the upper end of sealing device is with externally threaded connection end, and inside is provided with the outlet of through sealing device.
Further: on described sealing device, be additionally provided with the loosing and tightening structure for clamping sealing device.
Further: between described cooling wall water pipe, seal connection by high-pressure water pipe.
Further: described sealing gasket is rubber blanket.
The beneficial effects of the utility model are: by utilizing sealing device to cover on the mouth of pipe of cooling wall water pipe, pass through screw thread
It is connected with ferrule, on the one hand will not extrude the mouth of pipe and make the inside contraction distortion of the mouth of pipe, on the other hand when carrying out pressure testing experiment,
By outside pressure in water pipe, sealing device can limit the mouth of pipe and the most outwards be deformed, and other parts pass through screw thread too
Being connected with sealing device, whole pressure testing device each junction sealing is good；It is this utility model simple in construction, reusable,
Construction speed can be greatly saved, reduce experimentation cost.

Detailed description of the invention
For the ease of understanding this utility model, below in conjunction with the accompanying drawings this utility model is further detailed.
As it is shown in figure 1, this utility model blast furnace copper cooling stave hydraulic pressure pressure testing device, on cooling wall 1, all water pipes all connect
After sealing device 2, water inlet pipe 51 is sequentially connected with water inlet ball valve 3 and Pressure gauge 4, the external hydraulic test pump of water inlet ball valve 3, water outlet again
Pipe 52 connects outlet ball valve 6, seals against each other connection between remaining cooling wall water pipe 53, during owing to carrying out hydraulic pressure pressure testing, cold
But the pressure within wall water pipe 53 is very big, and the parts therefore connecting each cooling wall water pipe 53 are also required to bear the biggest pressure,
The present embodiment is selected high-pressure water pipe 7 carry out the connection between each cooling wall water pipe 53.
As in figure 2 it is shown, described sealing device 2 lower end is for carrying female dome structure, the top of dome structure is provided with
Sealing gasket 21, sealing gasket 21 directly to contact with the mouth of pipe of water pipe, can not damage the mouth of pipe, therefore while ensureing sealing
Sealing gasket 21 selects the rubber blanket that good seal performance, material are softer；Sealing device 2 is all threadeded with all water pipes, seals dress
The upper end putting 2 is that inside is provided with the outlet 23 of through sealing device 2 with externally threaded connection end 22.Sealing device 2 in order to
Ensureing that the mouth of pipe outwards will not deform because being under pressure, therefore sealing device 2 needs bigger intensity, and whole sealing device 2 is by casting
Ironworking forms.
As shown in Figure 2 and Figure 3, owing to sealing device 2 is threaded connection with the water pipe on cooling wall, twist for convenience
Sealing device 2 is installed, and is provided with loosing and tightening structure 24 on sealing device 2, loosing and tightening structure 24 be both sides be the step of plane
Structure, operator can use instrument to install or remove sealing device 2 by clamping loosing and tightening structure 24, time saving and energy saving.
When utilizing this utility model to carry out hydraulic pressure pressure testing experiment, all parts is connected after fixing, open water inlet ball
Valve 3 and outlet ball valve 6, then open the hydraulic test pump connected on water inlet ball valve 3, until air after outlet pipe 52 is drained, closes
Close outlet ball valve 6, until the pressure of Pressure gauge 4 display exceedes the authorized pressure value of design, close hydraulic test pump immediately and enter
Whether mouth of a river ball valve 3, then declined by the numerical value of observation Pressure gauge 4 and determine whether to there is seepage.
