Description
Technical field
A kind of feedway is the utility model is related to, belongs to energy efficiency technical field, and in particular to a kind of constant pressure supply
Device.
Background technology
Existing constant pressure feedway uses electric-control system and pressure-reducing valve mostly, and the equipment requirement precision of electric-control system is high,
Power consumption, energy consumption are larger, even if can still consume substantial amounts of electric energy in the standby state.Electric-control system maintains supply pressure
The constant increase that will certainly cause cost of investment and the follow-up electricity charge, the increase of maintenance cost, can also cause the waste of the energy,
In addition, pressure-reducing valve precision is low.
In summary, a kind of new technical scheme is needed in the prior art, solves the constant device of some consumption, using electricity
The problem of cost caused by control system is high, the follow-up electricity charge and maintenance cost are high, energy waste and pressure-reducing valve precision is low asks
Topic.
Utility model content
The purpose of this utility model is to provide a kind of gas constant pressure feedway, on the one hand solves the constant dress of some consumption
Put or equipment is using the problem of cost caused by electric-control system is high, the follow-up electricity charge and other maintenance costs are high, on the other hand
Solves the problems, such as energy waste, in addition, also solving the problem of pressure-reducing valve precision is low.
To solve the above problems, the utility model provides following technical scheme：A kind of constant pressure feedway, it is characterized in that：
Including high voltage supply device, constant pressure supply cylinder, vacuum reservoir, piston I, piston II, attachment means, consumer, the high pressure supplies
Cylinder is supplied to tank with constant pressure by the first connecting pipe to be connected；The constant pressure supply cylinder passes through the second connecting pipe and consumer
Connection；Valve is equipped with first connecting pipe and on the second connecting pipe；The piston I, piston II are separately positioned on
In constant pressure supply cylinder, vacuum reservoir, and piston I, piston II are fixedly connected by attachment means；
Further, second connecting pipe is provided with pressure gauge.
Following beneficial effect can be brought using the utility model of above-mentioned technical proposal：
For the constant device of consumption or equipment, maintain pressure constant using the utility model of pure device class
Than maintaining pressure constant using electric-control system, there is the effect for significantly reducing cost and reducing the follow-up electricity charge and maintenance cost
Fruit, and it is higher than using the constant pressure feedway precision of pressure-reducing valve.
For country, electric power resource has been saved, has responded the proposal of the energy efficiency that country proposes under existing situation.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further elaborated to the utility model：
Fig. 1 is the utility model structure diagram.
In figure, 1- high voltage supplies device, 2- constant pressures supply cylinder, 3- vacuum reservoirs, 4- pistons I, 5- pistons II, 6- connections dress
Put, 7- consumers, the connecting pipes of 8- first, the connecting pipes of 9- second, 10- valves, 11- pressure gauges.
Embodiment
As shown in figure 1, a kind of constant pressure feedway, it is characterized in that：Including high voltage supply device 1, constant pressure supply cylinder 2, true
Empty cylinder 3, piston I 4, piston II 5, attachment means 6 and consumer 7, the high voltage supply device 1 pass through the first connecting pipe 8
It is connected with constant pressure supply cylinder 2；The constant pressure supply cylinder 2 is connected by the second connecting pipe 9 with consumer 7；Described first
Valve 10 is equipped with the connecting pipe 9 of connecting pipe 8 and second；The piston I 4 is arranged in constant pressure supply cylinder 2, and piston I 4
It is connected with constant pressure supply cylinder 2；The piston II 5 is arranged in vacuum reservoir 3, and piston II 5 is connected with vacuum reservoir 3；
The piston I 4 and piston II 5 are fixedly connected by attachment means 6；
Further, second connecting pipe 9 is provided with pressure gauge 11.
In addition, the smooth enough that the inwall of constant pressure supply cylinder 2 and vacuum reservoir 3 is done, reduces energy loss and improves precision, piston
I 4, tight, the phenomenon that will not be leaked is coordinated between piston II 5 and constant pressure supply cylinder 2, vacuum reservoir 3.
Operation principle of the present utility model：
The valve 10 being first turned on the first connecting pipe 8, the effect of the valve 10 on the first connecting pipe 8 are：Work as perseverance
When gas pressure intensity in pressure supply cylinder 2 reaches a standard atmospheric pressure, high voltage supply device 1 stops supplying to constant pressure supply cylinder 2.
Now, the valve 10 on the second connecting pipe 9 is closed, and high voltage supply tank 1 supplies to constant pressure supply cylinder 2, when second
After valve 10 on connecting pipe 9 is opened, the effect of the valve 10 on the second connecting pipe 9 is：When constant pressure supplies the gas in cylinder 2
When body pressure reaches a standard atmospheric pressure, constant pressure supply cylinder 2 supplies to consumer 7.Now, piston I 4, piston II 5, company
The entirety that connection device 6 forms reaches balance under ambient pressure effect with the pressure in constant pressure supply cylinder 2, when device is horizontal positioned
In outside pressure it is considered that when constant place at the uniform velocity demand and supply quantity delivered is less than constant pressure supply cylinder volume
P1 × s1=p × (s1+s2)-f
In formula, p1 is the pressure in constant pressure supply cylinder 2, and p is outside pressure, and s1 is the cross-sectional area of piston I 4, and s2 is work
II 5 cross-sectional area is filled in, f is resistance；Obtain
In formula, p, s1, s2, f can consider constant, so p1 is constant, the supply of present apparatus constant pressure, the above is this practicality
The new principle for realizing constant pressure supply, in addition, for different consumers 7, can set different constant pressure supply values p1, lead to
Cross
Understand, give rational s1, s2 value, the pressure p1 that constant pressure is supplied in cylinder 2 can be just arranged to the value needed, led to
Cross the pressure gauge 11 being arranged on the second connecting pipe 9 can read constant pressure supply cylinder 2 in pressure values.
It is described above, preferable embodiment only of the present utility model, but the scope of protection of the utility model is not
Above example is only limitted to, any those skilled in the art is in the technical scope of the offer of the invention, according to this reality
With the equivalent substitution made by new technical scheme and its inventive concept or change, should all cover in protection of the present utility model
In the range of.
