Abstract
The utility model discloses a circulating water mechanism of boiler has solved the problem that circulating water in -process cooling tube is explode by the high pressure, and its technical scheme main points are including boiler and water tank, be connected with the cooling tube between boiler and the water tank, the cooling tube is arranged in the cooling trough, the cooling tube is equipped with the branch pipe of intercommunication water tank, prop up the intraductal pressure check valve that can bear set pressure that is equipped with, be equipped with the steel ball that seals in the pressure check valve, the steel ball has adjusting bolt through the compression spring butt, it has the panel of expanding to contradict between adjusting bolt's thread end and the compression spring, the branch pipe has the fin with the outside stack cover of cooling tube, has the fin clearance between the adjacent fin, reaches effectively to become the circulating water with the steam reforming, avoids the problem of cooling tube blasting.
Description
Technical field
This utility model relates to boiler, particularly to the circulating water mechanism of boiler.
Background technology
When the output of Boiler Steam is more than usage amount, unnecessary steam is expelled directly out, and the waste to steam is bigger.Therefore occurred in that the system recycling Boiler Steam.
Now retrieving the Chinese patent document one boiler steam circulation system of a publication number CN201568950U, unnecessary carrying out is reclaimed and enters water tank by it.
But steam has bigger pressure when entering water tank, and excess steam is converted into cooling tube wall all ratios relatively thin (having crossed more preferable heat conduction, accelerate steam condensation) of water, long-time extruding will make cooling tube burst.
Utility model content
The purpose of this utility model is to provide the circulating water mechanism preventing cooling water pipe from bursting.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of circulating water mechanism of boiler, including boiler and water tank, being connected and have cooling tube between described boiler and water tank, described cooling tube is placed in bosh, described cooling tube is communicated with the arm of water tank, is provided with the pressure check valve that can bear both constant-pressures in described arm.
By using technique scheme, unnecessary steam is returned in water tank through the condensation of bosh by cooling tube.When the pressure that steam pressure in cooling tube is set up more than pressure check valve, pressure check valve is opened so that steam circulates in arm with cooling tube, decreases the pressure of cooling tube, prevents the explosion of cooling tube.
It is also preferred that the left be provided with the steel ball of sealing in described pressure check valve, described steel ball is abutted by compression spring regulation bolt.
By using technique scheme, screw regulation bolt compression further to compression spring or stretch out, regulating the maximum pressure of arm the most according to demand so that high steam is difficult in cooling tube be formed, and prevents the explosion of cooling tube.
It is also preferred that the left conflict between the end of thread and the compression spring of described regulation bolt have extended surface plate.
By using technique scheme, extended surface plate adds the contact area of regulation bolt and compression spring, and compression spring is effectively compressed.
It is also preferred that the left the external stack of described arm and cooling tube is cased with fin, there is between abutting fins gap.
By using technique scheme, fin is conducive to the heat radiation of cooling tube, it is simple to the rapid condensation of steam, reduces the air pressure in cooling tube, prevents the explosion of cooling tube.
It is also preferred that the left described arm is connected by three way cock with cooling tube.
By using technique scheme, three way cock installs convenient, and it is convenient to change.
It is also preferred that the left described cooling tube is made of copper with arm.
By using technique scheme, copper has good heat conductivity, it is simple to the rapid condensation of steam, reduces the air pressure in cooling tube, prevents the explosion of cooling tube.
In sum, this utility model is had the advantages that and is limited the maximum pressure of cooling tube by the pressure check valve on arm, when cooling tube pressure is excessive, arm pressure check valve is opened, steam flow channel cross section is increased, reduce the pressure in cooling tube, prevent cooling tube from bursting because of hypertonia.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
Embodiment: (circulating water mechanism), as it is shown in figure 1, the gas outlet of boiler 1 is connected with water tank 2 by cooling tube 4, excess steam is back to water tank 2 by cooling tube 4.The upstream extremity of cooling tube 4 is introduced in bosh 3, and cooling water pipe is thicker at this position tube wall, has good explosion prevention function.
The interlude of cooling tube 4, in bosh 3, is placed with substantial amounts of cooling water in bosh 3, this cooling water is for absorbing the heat energy that cooling tube 4 is released, and the cooling tube 4 at this is made of copper, and utilizes the heat conductivility that copper is good.
Being cased with substantial amounts of fin 7 on the outer wall of cooling tube 4, fin 7 is waveform, and corrugated foldover design adds the area of dissipation of fin 7, accelerates the cooling tube 4 condensation to steam.
As in figure 2 it is shown, cooling tube 4 is at the upstream tube of bosh 3, being welded with an arm 5, arm 5 is made of copper, and is threadeded by three way cock 8 between cooling tube 4 with arm 5.Upstream port at arm 5 and the downstream position three way cock 8, threaded have pressure check valve 6.
As it is shown on figure 3, pressure check valve 6 has spherical steel ball 61 to abut, the right-hand member of steel ball 61 abuts compression spring 62, and the right-hand member of compression spring 62 abuts regulation bolt 63.By screwing or unscrew regulation bolt 63, can effectively control the abutting pressure of steel ball 61.The end of thread of regulation screw is connected with extended surface plate 65, and extended surface plate 65 is circular slab, and extended surface plate 65 abuts completely with the end of compression spring 62.
