Technical field
The utility model relates to a kind of water supply equipment, particularly relates to a kind of without cutting down water soot blower device in pipeline in negative pressure pumping plant.
Background technique
In the prior art, water soot blower is produced because many reasons causes flow rate of liquid in pipeline to change suddenly in pressure piping, mutually superpose at water soot blower reciprocating vibration process medium wave and increase with can produce between ripple, this not only can affect equipment of pumping station and run, and pipeline breakage fracture can be caused when water soot blower superposition exceedes pipeline bearing capacity, thus whole transporting system cannot be worked.
Therefore farthest reduce hydrodynamic pressure ripple to the impact of liquid line transport system, the working stability improving system is even more important; In current convection cell pipeline, water hammer control roughly can be summarized as Four types: the first kind is water filling or the voltage stabilizing of air injection buffering, thus controls water hammer pressure vibration in pipeline, prevents the boosting that water hammer is too high.Such have surge tower, air tank, air injection valve etc., and these class methods are taken up an area greatly, cost is high, and the air in filling line will lead to new water hammer as do not got rid of in time or deal with improperly; Equations of The Second Kind carries out valve regulated and control, such have various types of buffer valve, valve is closed lentamente and is opened the variance ratio that can reduce flow velocity in pipeline, thus reduce rising and the reduction of water hammer pressure, these class methods can prevent water hammer from occurring to a certain extent, but limited to the treatment effect of the hammer that floods; 3rd class is sluicing step-down, avoids pressure to skyrocket, and this type has pump-stopping water hammer canceller, rupture pressure disc etc.This class methods complex structure, maintenance difficult; Rupture pressure disc is subject to the impact such as material and silent film means of fixation and is difficult to determine its specified bursting pressure; 4th class is the water pump assembly of selecting rotary inertia large or is installed in addition with inertial flywheel etc., and this type method can prevent water hammer from occurring to a certain extent, but limited to the treatment effect of the hammer that floods.In sum, prior art is comparatively large because being subject to the impact such as actual place, cost, maintenance, thus design a kind of method simple, take up an area little, easy care, effective device are necessary.
Model utility content
In view of this, main purpose of the present utility model is to provide a kind of without cutting down water soot blower device in pipeline in negative pressure pumping plant, pass through the technical program, hyperbaric chamber cylinder and low-pressure cavity cylinder pass through Flange joint, pressure reducing orifice is between two chamber cylinders, intake pipe and water outlet are all positioned on low-pressure cavity cylinder, the technical program makes simple, easy to maintenance, the pressure caused by water hammer is linked in pumping plant piping after hyperbaric chamber buffering and orifice plate decompression, and because orifice plate exists, make the water hammer entering tank body involve energy cannot discharge fast, so the water soot blower of the certain wavelength out of phase of water hammer can be made in tank body to superpose abatement, ensure that the safety and stability of system.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of without cutting down water soot blower device in pipeline in negative pressure pumping plant, comprise tank body, described tank body is made up of hyperbaric chamber cylinder and low-pressure cavity cylinder, it is characterized in that, comprise pressure reducing orifice, intake pipe and water outlet, the opening end of described hyperbaric chamber cylinder and low-pressure cavity cylinder is respectively arranged with adpting flange, two adpting flanges on described hyperbaric chamber cylinder and low-pressure cavity cylinder are oppositely arranged, pressure reducing orifice is arranged between two adpting flanges, by fixing bolt by hyperbaric chamber cylinder, low-pressure cavity cylinder and pressure reducing orifice are connected to an entirety, described intake pipe extend in hyperbaric chamber cylinder through low-pressure cavity tube rear end and pressure reducing orifice, described water outlet is arranged on the circular arc sidewall of low-pressure cavity cylinder.
Described hyperbaric chamber cylinder is identical with low-pressure cavity cylinder diameter, and the length dimension of described hyperbaric chamber cylinder and low-pressure cavity cylinder is respectively the 3-5 of its diameter doubly.
Intake pipe internal diameter on described low-pressure cavity cylinder and water outlet equal diameters, the internal diameter of described hyperbaric chamber cylinder and low-pressure cavity cylinder is 2-3 times of intake pipe internal diameter and water outlet diameter.
Described pressure reducing orifice is evenly distributed with some vents, and due to pressure reducing orifice existence, making the water hammer entering tank body involve energy cannot discharge fast, so the water soot blower of the certain wavelength out of phase of water hammer can be made in tank body to superpose abatement.
Beneficial effect after employing technique scheme is: a kind of without cutting down water soot blower device in pipeline in negative pressure pumping plant, pass through the technical program, a kind of function admirable is proposed, make simple, device for cutting down pressure piping pressure wave easy to maintenance, high-pressure chamber and low pressure volumes is formed by end socket and hollow cylinder, pressure reducing orifice is provided with between two cavitys, pressure wave is made to be linked in pumping plant piping after hyperbaric chamber buffering and pressure reducing orifice decompression, and because pressure reducing orifice exists, make the water hammer entering tank body involve energy cannot discharge fast, so the water soot blower of the certain wavelength out of phase of water hammer can be made in tank body to superpose abatement, ensure that the safety and stability of system.
Accompanying drawing explanation
