Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, the present invention is a kind of thermal-collecting tube cutout valve, main body includes the valve body shell an of tubular, valve
Body housing includes a water inlet end and a discharge ends, and a connection ring has been threadably secured in valve body shell, even
It connects and is fixed with a pressure rings by several dowel A on the one end of ring, several drainage hole A are provided between dowel A,
The end of the pressure rings is socketed with a retaining ring, detachable by screw thread between the inner wall of retaining ring and the outer wall of pressure rings
Connection, is provided with a compression ring on the inner wall of retaining ring, and clamping between compression ring and the end of pressure rings has a spring
Piece, the surface of the spring leaf are coated with rubber sealant B, and the elasticity that a dome shape is provided in the middle part of spring leaf is convex
It rises, has also been connected through a screw thread a water guiding ring in the other end of connection ring, water guiding ring is tapered configuration, the flaring of water guiding ring
End is fixed on the inner wall of connection ring, the discharge ends of the necking end of water guiding ring towards valve body shell, while the necking of water guiding ring
Drainage gap is reserved between end and the end of pressure rings；Drain bar is threadedly secured to valve body shell and corresponds to water inlet end
Position is provided with the infiltration groove of dome shape corresponding with the spherical surface of spring leaf in the middle part of drain bar, in the infiltration groove
Surface on be provided with rubber sealant A, be provided with several drainage hole B on infiltration groove, drainage hole B runs through drain bar；
A precompressed is connected with by several dowel B on the water inlet extreme direction that the connection ring corresponds to valve body shell
Component is adjusted, it includes the adjusting set being fixedly connected with dowel B that precompressed, which adjusts component, and one is slidably connected in adjusting set
A mandril has also been connected through a screw thread a housing screw in adjusting set, passes through diastole spring between housing screw and mandril
Elastic connection, mandril press against on spring leaf under the driving of diastole spring；
A sealing drive rod is also rotatably connected on the valve body shell, sealing drive rod penetrates into outside valve body
Inside shell, when sealing drive rod rotates in order to prevent, a large amount of hot water can be taken out of because local gap changes, therefore sealing drive rod
It is connect, and penetrated into pressure rings by seal with elastometic washer between valve body shell, the end of sealing drive rod is fixed with one
A pushing block is fixed with a trackwheel in another end of sealing drive rod, and pushing block is under the driving of trackwheel
Rotation, when pushing block turns to valve body shell draining extreme direction, pushing block is pressed on spring leaf, so that spring leaf is pressurized instead
To fold.
In use, first by adjusting housing screw, so that mandril is pressed on spring leaf, so that by one on spring leaf
Fixed precompressed guarantees spring leaf after thermal-arrest tracheal rupture, and encountering lesser pressure difference can rapidly react；
One end of valve is fixed to the thermal-collecting tube link position of water tank simultaneously, the other end is connected to the opening of thermal-collecting tube
On, heat insulation layer should be wrapped up outside valve to meet the needs of heat preservation.
Then when thermal-collecting tube is in normal condition, hydraulic balance between thermal-collecting tube and water tank, the pressure of spring leaf two sides
It is identical, actuation will not occur, water passes through drainage gap, drainage hole A, drainage hole B via water inlet end to discharge ends, and thermal-collecting tube is broken
After splitting, thermal-collecting tube decompression, water tank lateral pressure becomes larger, spring leaf compressive deformation, towards draining extreme direction fold, realizes to drainage hole
The closing of B is prevented hot water in water tank from continuing to be discharged, improves safety to disconnect water route；
And in maintenance, in water tank, moisture storage capacity is reduced, and will lead to the opening of valve, so that hot water can be from thermal-collecting tube
Discharge can rotate sealing drive rod at this time, and when pushing block turns to valve body shell draining extreme direction, pushing block is pressed to bullet
On reed, the closing to drainage hole B is realized in the reversed fold so that spring leaf is pressurized；Entire thermal-collecting tube can be torn open after closing
Under, without leaking.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
