Abstract

A kind of gate sealing configuration, comprise pipeline and be arranged on the gate at pipe end place, the end face of described pipeline is provided with annular groove relative with gate, inner seal circle is installed in annular groove, the pressurising chamber passing into high pressure is formed between annular groove and inner seal circle, pressurising chamber is by pressure piping and pressure-source communication, between inner seal circle and gate, outer side seal circle is installed again, described outer side seal circle is the arc seal ring of opening towards inner seal circle, the two ends up and down of its opening portion respectively with inner seal circle outside the upper and lower sides at middle part offset.When after closing gate, in pressurising chamber, pressure is provided by pressure piping, thus inner seal circle and outer side seal circle are under pressure, to gate end motion, until the outer side seal circle near gate one end is tightly pushed up on gate, the surface of outer side seal circle tightly contacts with door surfaces, thus by seal for pipe joints.

Description

A kind of gate sealing configuration
Technical field
The utility model relates to sealing configuration, the gate sealing configuration particularly between a kind of pipeline and gate.
Background technique
In large pressurized vessel and pipeline thereof, sometimes need to arrange closing gate pipeline, due to pipe diameter large (diameter >=2 meter), general existing gate is difficult to meet the demands or to pay cost for meeting the demands higher.Meanwhile, in waterworks, often carry water with large-scale pipeline, these large-scale pipelines may be positioned at ground or be embedded in underground, and even pipeline is exactly subterranean tunnel, in some position of these conveyance conduits, can need to arrange closing gate pipeline.In order to avoid leaking, then use seal arrangement in closed position.Because the hydraulic pressure at these occasion lower seal places can be very large, adopt general existing sealing configuration to be difficult to guarantee sealability, cannot usage requirement be met.
Model utility content
The utility model aims to provide a kind of good seal performance, can be suitable for the gate sealing configuration of hyperbaric environment lower seal pipeline.
A kind of gate sealing configuration described in the utility model, comprise pipeline and be arranged on the gate at pipe end place, the end face of described pipeline is provided with annular groove relative with gate, inner seal circle is installed in annular groove, the pressurising chamber passing into high pressure is formed between annular groove and inner seal circle, pressurising chamber is by pressure piping and pressure-source communication, between inner seal circle and gate, outer side seal circle is installed again, described outer side seal circle is the arc seal ring of opening towards inner seal circle, the two ends up and down of its opening portion respectively with inner seal circle outside the upper and lower sides at middle part offset.
A kind of gate sealing configuration described in the utility model, when after closing gate, in the pressurising chamber in annular groove, pressurized gas or pressure oil or press water is filled with by pressure piping, can make inner seal circle under the effect of pressurized gas, pressure oil or press water, to gate end motion, tightly be pressed on gate until inner seal circle promotes outer side seal circle, the surface of outer side seal circle and door surfaces close contact, thus by seal for pipe joints.Because outer side seal circle is the arc seal ring of opening towards inner seal circle, the two ends of its opening offset with the middle part of inner seal circle respectively, pushed at high pressure inner seal circle is filled with when outwards moving in pressurising chamber, the middle part of inner seal circle can extrude outer side seal circle opening portion, the outward opening of outer side seal circle is opened be pressed on the wall of groove, thus guarantee that sealability is excellent.
Because pressure source is communicated with the pressurising chamber inside annular groove by pressure piping, pressure source is only needed to provide pressure to be greater than the pressure of the medium in pipeline, just can ensure that seal ring surface energy keeps tightly contacting with the surface of gate always, thus ensure that gate seals reliably.By the pressure that regulated pressure source provides, the reliable sealing of pipeline under any pressure condition can be adapted to.Because outer side seal circle is C RunddichtringO, U-shaped seal ring, V-shaped seal ring or y-type seal ring, open part is towards inner seal circle, therefore in pressurising chamber after charged pressure, while pressure promotes to move outside inner seal circle, the curved portion of inner seal circle also may be made to deform heave, make the top squeeze outer side seal circle opening portion of inner seal circle, the outward opening of outer side seal circle is opened to be pressed on the wall of groove, simultaneously, the tight of outer side seal circle is fitted on gate, ensures the sealability of gate more reliably.

Fig. 2 is that Fig. 1 A-A is to sectional drawing;
Fig. 3 is Fig. 2 part B partial enlarged drawing.
Embodiment
A kind of gate sealing configuration, as shown in Figure 1 to Figure 3, comprise pipeline 1 and be arranged on the gate 2 at pipe end place, the end face of described pipeline 1 is provided with annular groove 3 relative with gate 2, inner seal circle 4 is installed in annular groove 3, the pressurising chamber passing into high pressure is formed between annular groove 3 and inner seal circle 4, pressurising chamber is by pressure piping 5 and pressure-source communication, between inner seal circle 4 and gate 2, outer side seal circle 6 is installed again, described outer side seal circle is the arc seal ring of opening towards inner seal circle 4, the two ends up and down of its opening portion respectively with inner seal circle 4 outside the upper and lower sides at middle part offset.
Described outer side seal circle 6 is C RunddichtringO, U-shaped seal ring, V-shaped seal ring or y-type seal ring.
Described pipeline 1 end face arranges annular boss, annular boss arranges annular groove 3; Or flange is set at described pipeline 1 end face, end face of flange arranges annular groove 3; Or directly dig annular groove 3 at pipeline 1 end face.
Described inner seal circle 4 and outer side seal circle 6 are rubber or tartan, or other organic or inorganic material.
Described pressure source is pressurized gas, pressure oil or press water, and described pressurized gas is air or inert gas or carbon dioxide or mixed gas.
The described device to pressure piping 5 supplying compressed gas is air compressor or the gas cylinder that pressurized gas is housed or gas tank or the gas holder that pressurized gas is housed.
The described device having the water of pressure to pressure piping 5 supply is water pump or water pot or water tower or bucket or water bottle or other water storage unit.
The described device having the oil of pressure to pressure piping 5 supply is electric pump station or oil pressure station.
