Description

A kind of elastic membrane protecting water hammer device
Technical field
It the utility model is related to the technical field of water conveying, more particularly to the one kind used in long distance water transmission pipeline system Elastic membrane protecting water hammer device.
Background technology
Long range water supplying pump system often due to pumping accident and water hammer accident occurs, cause pressure pipeline, water pump, valve Etc. wrecking, supply water and interrupt, cause heavy losses.The pump-stopping water hammer of water supplying pump system is to have barotropic wave after first having decompression ripple Transient process, if can prevent pressure from reducing in time, it just can effectively reduce pressure rise.
At present, prevent the method that pressure reduces in Calculations of Hydraulic Transient from there are two kinds:One kind is the water filling into pipeline, another It is the gas injection into pipeline.The protecting water hammer measure of the water filling into pipeline is mainly surge tower (case) and air tank;Noted into pipeline The protecting water hammer measure of gas is mainly air valve.Surge tower (case) and air tank cost are high, operational management inconvenience;Air valve only has When the pressure in pipeline is less than atmospheric pressure could gas injection, therefore its protecting water hammer effect is limited.
The effect of air tank is that it is installed in water pump in protector of the hydraulic pipeline system for preventing positive/negative-pressure Near exit, when water hammer accident occurs, pump outlet pipeline causes pressure to decline because flow declines, initial in air tank Gas pressure be more than fluid pressure in pipeline, the water in air tank is pressed into pipeline, to supplement the stream of liquid in pipeline Amount declines, and declines so as to alleviate the pressure of pump outlet;When barotropic wave reaches pump outlet, the pressure in pipeline is more than Gas pressure in air tank, liquid in pipeline is because the effect of pressure difference is pressed into tank body, so as to alleviate exit of pump Pressure rise.The presence of compressed gas can discharge the pressure wave in pressure energy or extraction duct in air tank.
At present, conventional air tank has two types, non-divergence type air tank and Split type air tank, for non-divergence type For air tank, the phenomenon that air is dissolved in water at the contact surface of air and water be present, but either Split type air tank is still Non- divergence type air tank, all have a problem that to be exactly gas loss, it is therefore desirable to which air compressor carries out tonifying Qi to it.Except this Outside, engineering high, that regulating power is big is required for long distance water transfer project or to protecting water hammer, it is necessary to air tank appearance Product is excessive, and it is difficult that large-scale promotion is applied into Practical Project that this, which allows for traditional air tank,.And air tank is typically installed On the pipeline near exit of pump, its protection effect is limited.
Utility model content
For above-mentioned problem of the prior art, there is provided the utility model provides a kind of elastic membrane protecting water hammer device, In Calculations of Hydraulic Transient, the dependence to air tank is reduced, can timely and effectively suppress water hammer harm.
Technical scheme provided by the utility model:
A kind of elastic membrane protecting water hammer device, including cylinder of steel, rubber diaphragm, regulation spring, clamping plate, pogo barrel, spring Adjusting knob, air valve, drain valve, service valve, flange, the cylinder of steel set air valve, drain valve, service valve, flange, spring Sleeve pipe is welded on cylinder of steel, and the regulation spring is placed in inside pogo barrel, and spring adjusting knob passes through regulation spring and clamping plate Connect, rubber diaphragm is arranged between clamping plate, and rubber diaphragm is fixed on cylinder of steel by flange.
Preferable technical scheme, the regulation spring is compression helical spring.
In above-mentioned technical scheme, the rubber diaphragm is prepared for nitrile rubber.
In above-mentioned technical scheme, the flange welding is in cylinder of steel inwall.
In above-mentioned technical scheme, the elastic membrane protecting water hammer device is arranged in aqueduct along hydraulic pipeline to be deposited In local high spot.
The beneficial effects of the utility model are:It is simple in construction, it is safe and reliable to operation;It is easy to use, solve tonifying Qi difficulty The problems such as;And convenient maintenance, it can be installed along journey;Reduce the dependence to the volume size of air tank.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model embodiment structural representation.
Wherein:1st, cylinder of steel;2nd, rubber diaphragm;3rd, spring is adjusted;4th, clamping plate;5th, pogo barrel;6th, spring adjusting knob;7、 Air valve;8th, drain valve;9th, service valve;10 flanges.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, Obviously, described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on this practicality Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made Example is applied, belongs to the scope of the utility model protection.
According to Fig. 1, a kind of elastic membrane protecting water hammer device, including cylinder of steel, rubber diaphragm, regulation spring, clamping plate, bullet Spring sleeve pipe, spring adjusting knob, air valve, drain valve, service valve, the cylinder of steel set air valve, drain valve, service valve, bullet Spring sleeve pipe is welded on cylinder of steel, and flange welding is placed in inside pogo barrel in cylinder of steel inwall, the regulation spring, spring regulation rotation Button connects through regulation spring with clamping plate, and rubber diaphragm is arranged between clamping plate, and rubber diaphragm is fixed on cylinder of steel using flange, Rubber diaphragm selects that the nitrile rubbers of elevated pressures can be born, and utilizes the deformation up and down of rubber diaphragm and the compression of spring and extensive It is multiple to suppress the harm of water hammer.
The operation principle of the present invention:Elastic membrane protecting water hammer device is arranged in aqueduct along hydraulic pipeline has office Portion's high point.Among Calculations of Hydraulic Transient, when pipeline pressure rises, and N point pressures are more than the elastic force of spring, spring shortens, elasticity The upward deformation of film, it is allowed to which pipeline water body enters in tank, in pipeline water body air inlet tank.When water pump loses transmission or termination of pumping, Pump rotary speed declines, and flow reduces, and at this moment the elastic force of spring is higher than water-supply-pipe point N pressure, spring elongation, the downward shape of elastic membrane Become, make water body outflow supply pipeline in air tank, to reduce the fall off rate of pipeline water flow flow velocity, avoid pipeline pressure from dropping to Below atmospheric pressure or steam pressure.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be described with power The protection domain that profit requires is defined.
