Abstract
The utility model discloses a flange type pipeline drainage valve, which belongs to accessory equipment of liquid delivery pipelines, in particular to a flange and valve combined body for pipeline drainage. The flange type pipeline drainage valve is characterized in that an exhaust hole is arranged on a round flange in the radial direction, an exhaust pipe with a valve is arranged on the outer circumferential surface of the flange, and the exhaust pipe is communicated with the exhaust hole. The flange type pipeline drainage valve has the beneficial effects that the flange type pipeline drainage valve enables the exhaust pipe to be upwardly arranged by arranging and connecting two butt flange plates and corrosion prevention rubber pads in a pipeline, controls pipeline gas to drain through a drainage valve, and is suitable to connect pipelines which need to drain a little gas. The flange type pipeline drainage valve has the advantages of simple structure, convenient mounting and easy operation, and has high practicability.
Description
Technical field
The utility model belongs to the accessory of pipe-line for conveying liquids, and particularly a kind of flange for pipe evacuation and valve sets are fit.
Background technique
Conventionally in chemical process, usually need to utilize the method for azeotropic distillation that water is separated from system, one of them key equipment is oil and water seperator, is characterized in that condensed fluid flows in the middle of water knockout drum by a standpipe, and this position is under liquid level.Because azeotropic distillation is that the mode constantly refluxing by organic solvent carries out by water, so need the fluid-tight of a U-shaped pipe to enter water knockout drum to block steam in still after water knockout drum, consequently U-shaped pipe has a large amount of gas near the support arm of water knockout drum and cannot discharge, water knockout drum internal pressure is raise, liquid level in standpipe is corresponding rising also, even from condenser evacuation port, overflows.Conventionally solution is to strengthen the high potential difference of condenser and water knockout drum, or utilizes the method for repeatedly discharging liquid that gas is discharged.The former is subject to the restriction of spatial position sometimes, and the latter is dangerous operation, with potential safety hazard.
Model utility content
In order to overcome the problem existing in a small amount of gas discharge technology in existing chemical pipeline, the utility model provides a kind of flange pipeline exhaust-valve, and this flange pipeline exhaust-valve can be arranged on easily on pipeline body and can get rid of at any time a small amount of gas remaining in pipeline.
The utility model solves the technological scheme that its technical problem adopts: a kind of flange pipeline exhaust-valve, it is characterized in that: at circular flange, be provided with in the radial direction exhaust port, with valvular outlet pipe, be arranged on the outer peripheral surface of flange, outlet pipe is communicated with exhaust port.
The described end with valvular outlet pipe by with flange on the screw thread that cooperatively interacts of screw thread be arranged on the outer peripheral surface of flange, between the two with seal ring.
Described is welded on the outer peripheral surface of flange with valvular outlet pipe.
The beneficial effects of the utility model are that the utility model is connected in pipeline by inserting flange plate and the anticorrosion rubber cushion of two docking, make exhaust pipe mouth upwards, by the discharge of exhaust-valve gate control pipeline gas, be applicable to get rid of the pipeline connection of a small amount of gas, have simple in structure, easy for installation, the feature of processing ease, has higher practicability.
