Advantageously, carry at least the bearing of branch road 2, stop valve 6, the bearing of the first equalizing valve 10, the bearing of the second equalizing valve 11 and at least one part of the first hydraulic path 5 to make parts 30, preferably made by motlten metal.Preferably, the bearing that is used for the first bearing of the first temperature sensor 18a and/or is used for non-return valve 19 is also obtained by main body 30.Advantageously, the part of connecting tube 7 and/or the second hydraulic path 12 also can be obtained by described parts 30 at least.Preferably, at least a portion of the isolating switch 10a of the isolating switch 11a of the isolating switch 6a of stop valve and/or the second equalizing valve 11 and/or the first equalizing valve 10 and/or first sensor 18a and/or non-return valve 19 (perhaps whole) is contained in the described main body 30.
In installation process, described device should be set and equalizing valve 10 and 11 should be adjusted to the balance whole system and always guarantee the correct supply of current.
Use and whole system will installing to be connected in for 1 (comprising at least measurement mechanism 4), for example be connected in the pipeline of main system at the 3b of export department of the inlet portion 2a by will carrying branch road 2 and backflow branch road 3, and inlet portion 3a and the 2b of export department are connected in after user's pipeline, must carry out the following step.
At first, must the balance primary return, namely must balance comprise conveying branch road, user and backflow branch road and the primary return that in the course of normal operation of single user's heating system, works.In other words, must regulate the flow velocity of the water of flow through conveying branch road 2, use and backflow branch road 3.
In this first step, stop valve 6 must be opened, and namely is in the ON position, thereby so that the stream whole conveying branch road 2 of only flowing through is closed and carried to connecting tube 7.In other words, the isolating switch 6a of stop valve 6 closes the entrance (connecting tube 7) that leads to the first hydraulic path 5.
Flow through after the use, water is got back to backflow branch road 3.Advantageously, in this step, the backflow whole backflow branch road of must only flowing through for example can not disperse towards the first hydraulic path 5.For this purpose, the first hydraulic path 5 must be closed being used for and refluxes by for example being closed at least ball valve 15.
If shown in preferred implementation, also have the second hydraulic path 12, then can close corresponding ball valve 16 as in mode (Fig. 1) as an alternative or close corresponding ball valve 16 and in conjunction with closing ball valve 15, do like this and also have the purpose of closing first hydraulic path 5 of leading to backflow.In fact, by closing at least one in ball valve 15 and 16, the hydraulic path that is made of the unitary part of hydraulic path 5 and 12 gets around backflow, thereby guarantees the backwater backflow branch road 3 of only flowing through.
Can come balance primary return (change the position of isolating switch 10a and therefore change the flow velocity of the current of the primary return of flowing through) by acting on this first equalizing valve 10 the first equalizing valve 10 is opened or closed such position now, the Peak Flow Rate that concrete system allows in described position or the concrete required Peak Flow Rate of user can be read from measurement mechanism 4, and described measurement mechanism 4 plays the effect of instant flowmeter in this step.Preferably, the first equalizing valve 10 blocks in described position by for example lead-tight.
After the balance primary return, must balance recycle or bypass loop.
With reference to accompanying drawing, in setting step, recycle or bypass loop are by 5 simulations of the first hydraulic path.On the contrary, in the normal use procedure of device, real recycle or bypass loop are by 12 representatives of the second hydraulic path.In the situation that does not have the second hydraulic path 12 that the present invention sets, the first hydraulic path 5 plays the effect of setting loop and recirculation circuit in two independent processes.
In the process of carrying out the bypass equilibrium step, stop valve 6 is closed, and namely is positioned at the OFF position.Therefore, isolating switch 6a gets around the afterbody part 2d that carries branch road 2.Still according to illustrated preferred implementation, the ball valve 16 of the second hydraulic path 12 is closed and the ball valve 15 of the first hydraulic path 5 is opened.Water is from carrying the 2c of first of branch road 2 to flow to connecting tube 7, then from only flow through the first hydraulic path 5 and get back to boiler or get back to main system (Fig. 3) from described the first hydraulic path 5 measurement mechanism 4 of flowing through of described connecting tube 7.
Be similar to aforementioned explanation, described measurement mechanism 4 plays the effect of instant flowmeter herein again.
By acting on the second equalizing valve 11, therefore the position of isolating switch 11a regulate and the flow through flow velocity of recycle or bypass loop is also changed, until can be in the position that measurement mechanism 4 is read corresponding to the instant flow velocity of the recirculation water of the second predetermined value.
Described value can be preferably Peak Flow Rate or the required Peak Flow Rate of specific user that allows such as the particular system in the aforementioned balancing run, perhaps also can be larger value or such as the less value such as described peaked 60%.
In case equalizing valve 11 is regulated, preferably by for example lead sealing it is blocked now, thereby prevent that described equalizing valve 11 from from its optimum operation position unconscious and/or unnecessary movement occuring.Device 1 thereby system are now ready for carrying out proper operation.
For this purpose, the ball valve 15 of the first hydraulic path 5 is closed, if also have the second hydraulic path 12, then also can not use from now on described the first hydraulic path 5.On the contrary, the ball valve 16 of the second hydraulic path 12 is preferably opened.Equally preferably block ball valve 15 and/or ball valve 16 by lead-tight, thereby prevent from device is adjusted.In a preferred embodiment, the first hydraulic path 5 only is to set the loop, and the second hydraulic path 12 is common recycle or bypass loop.
In course of normal operation, in order to supply water to the user, stop valve 6 must be opened (being in the ON position) thereby get around the second hydraulic path 12, i.e. recirculation path.On the contrary, when not needing to supply water, stop valve 6 switches to closes or OFF position (seeing Fig. 2) and current flow through the second hydraulic path 12, enters the 3b of export department that carries branch road 3, thereby gets around the user and preferably get around equally measurement mechanism 4.
The measurement mechanism 4 because recirculation water that returns boiler is not flowed through, so current can not experience any pressure drop (Kv) that occurs when it flows through measurement mechanism 4, and therefore identical pressure drop preferably produces by described throttling element 17 again.
Should also be noted that, in the embodiment that does not have a branch road 12 of the present invention, measurement mechanism 4 record current, but these current and temperature contrast (between the position of 18a and 18b) are associated, this temperature contrast is void value in practice, and does not therefore have energy consumption.
The present invention has realized designed purpose and significant advantage.
The use of similar device makes it possible to regulate described device and balanced system in mode simply and fast, and need not to use any additional means such as chart or form.
And, according to the installation of device of the present invention and set and can also be carried out by those of ordinary skill, and need not at first will read and understand the deep technology ABC of chart.
At last, give the credit to equally flowmeter and thermo-recorder are incorporated into a measurement mechanism that can be coupled to the backflow branch road, described device simple in structure, light and volume is little.
At last, the cost of described device manufacturing and installation is low.
