Abstract
A device for blocking leakage under pressure belongs to the field of blocking leakage under pressure without stopping conveying of a material pipe, and is characterized by including an emptying pipe and an emptying valve, wherein a fixing device is arranged at one end of the emptying pipe, and the other end is communicated with the emptying valve. During the use, the fixing device of the emptying pipe is placed at a leakage point of the material pipe, so that leaked liquid or gas can be temporarily discharged or stored through the emptying pipe and the emptying valve, and the next sealing and blocking measure can be taken conveniently; and different sealing and blocking operations can be carried out specific to material pipes made of different materials. The time for preparing the method work is short, the materials are easy to get, the construction steps are simple, and the cost is low.
Description
Technical field
The utility model provides a kind of pressure sealing device, belongs to not pressure sealing field under the stopping transportation situation of materail tube.
Background technique
Because equipment, pipeline long-term operation cause defectives such as local reduction, corrosion failure, form and reveal; Mostly be media such as inflammable and explosive, High Temperature High Pressure because of the operating material system pipeline medium that goes into operation, pressure can not in time reduce, and pressure reduces the normal operation that can have influence on device, therefore must adopt the method for pressure sealing to rush to repair maintenance.
The method of pressure sealing was that leak site is measured in the past, and customization processing one cover mold is fastened in leak site with mold then, and injecting glue is carried out in inside, carries out leak stopping.Adopt the method, the mold process-cycle is long, and difficulty of construction is big, cost is high.
The model utility content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of construction simple, materail tube is the pressure sealing device under the stopping transportation situation not.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of pressure sealing device is characterized in that: comprise blow-down pipe and atmospheric valve, blow-down pipe one end is provided with fixing device, and the other end is communicated with atmospheric valve.
During use, the fixing device of blow-down pipe is placed on the leakage point of materail tube, makes the liquid or the gas that leak temporarily discharge or keep in by blow-down pipe and atmospheric valve, so that carry out further shutoff measure.
Wherein preferred version is:
Described blow-down pipe outer installment sleeve pipe, sleeve pipe is provided with saddle mouth interface, the sleeve pipe the other end and the airtight shutoff of blow-down pipe outer wall near fixing device one end.In materail tube non-inflammable and explosive medium, during as steam, nitrogen, catalyzer etc., can be with the saddle mouth interface position and the materail tube welded seal of sleeve pipe.After closing atmospheric valve, just can finish shutoff.
Described fixing device is the arc plate, and arc plate center is provided with through hole and is communicated with blow-down pipe.Be inflammable and explosive in materail tube, the dielectric leakage that can not get angry during as gasoline, gas, diesel oil etc., can be fixed the arc plate with rubber and clamp, and arc plate and blow-down pipe firmly are fixed on the leakage point position hermetically.
One side of described atmospheric valve is provided with a head.Make things convenient for auxiliary pipings such as fixing glue leather hose, plastic tube.
The beneficial effect that the utility model pressure sealing device is had is: comprise blow-down pipe and atmospheric valve, blow-down pipe one end is provided with fixing device, the other end is communicated with atmospheric valve, during use, the fixing device of blow-down pipe is placed on the leakage point of materail tube, make the liquid or the gas that leak temporarily discharge or keep in,, can carry out different shutoff operations by materail tube at different material so that carry out further shutoff measure by blow-down pipe and atmospheric valve.
This method work setup time weak point, material easily is equipped with, and construction sequence is simple, and cost is low.
Description of drawings
Fig. 1 is embodiment's 1 an of the present utility model structural representation;
Fig. 2 is embodiment's 2 an of the present utility model structural representation;
Wherein: 1, materail tube 2, leakage point 3, blow-down pipe 4, sleeve pipe 5, atmospheric valve 6, clamp 7, rubber 8, silk head.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1:
As shown in Figure 1, blow-down pipe 3 one ends are provided with fixing device, and the other end is communicated with atmospheric valve 5.
Blow-down pipe 3 outer installment sleeve pipes 4, sleeve pipe 4 is provided with saddle mouth interface, sleeve pipe 4 the other ends and the airtight shutoff of blow-down pipe 3 outer walls near fixing device one end.One side of atmospheric valve 5 is provided with a head, makes things convenient for auxiliary pipings such as fixing glue leather hose, plastic tube.
During use, the fixing device of blow-down pipe 3 is placed on leakage point 2 positions of materail tube 1, makes the liquid or the gas that leak pass through blow-down pipe 3 and atmospheric valve 5 temporary transient discharges or temporary, so that carry out further shutoff measure.In materail tube 1 non-inflammable and explosive medium, during as steam, nitrogen, catalyzer etc., can be with the saddle mouth interface position and materail tube 1 welded seal of sleeve pipe 4.After closing atmospheric valve 5, just can finish shutoff.If sleeve pipe 4 still feels to have leak pressure, can in the space between sleeve pipe 4 and the blow-down pipe 3, fill some asbestos by etc. thermal insulating material.
Embodiment 2:
As shown in Figure 2, blow-down pipe 3 one ends are provided with fixing device, and the other end is communicated with atmospheric valve 5.Fixing device is the arc plate, and arc plate center is provided with through hole and is communicated with blow-down pipe 3.One side of atmospheric valve 5 is provided with a head, makes things convenient for auxiliary pipings such as fixing glue leather hose, plastic tube.
During use, the fixing device of blow-down pipe 3 is placed on leakage point 2 positions of materail tube 1, makes the liquid or the gas that leak pass through blow-down pipe 3 and atmospheric valve 5 temporary transient discharges or temporary, so that carry out further shutoff measure.Be inflammable and explosive in materail tube, the dielectric leakage that can not get angry during as gasoline, gas, diesel oil etc., can be fixed with rubber 7 and 6 pairs of arc plates of clamp, and arc plate and blow-down pipe 3 firmly are fixed on the leakage point position hermetically.The method is only leaked with control in a short time, also need wait pipeline step-down, material excision, purge to get angry after qualified and remove a hidden danger.
The technique for fixing of fixing device and saddle mouth interface is processed as common prior art, its setting and use to industry technician and grasped in the utility model.
