Description

Multi-plate radiator

Technical field

The present invention relates to a kind of multi-plate radiator with a plurality of fin, described fin is connected to each other to row by adapter sleeve respectively, and in the zone that these fin connect, seal with respect to the external world by hermetically-sealed construction, first fin comprises built-in valve, it reaches the adapter sleeve between first fin and second fin, adapter sleeve is connected to fin via helicitic texture, this helicitic texture has: engage first screw thread of the first phase double thread in first fin and with respect to second screw thread of the first screw thread reverse rotation, described second is threadedly engaged with the second phase double thread in second fin; And be arranged in groove between first screw thread and second screw thread.

Background technology

This multi-plate radiator is known from italian patent 01300587.Herein, hermetically-sealed construction is the O-ring seal that is arranged between fin distolateral.When adapter sleeve was tightened, the sealing structure was compressed.The rostrum of the built-in valve adapter sleeve between first fin and second fin of coming in and going out.Seal makes between pipe and the adapter sleeve and seals.

Because this design exists the risk, the especially internal leakage that leak, can not guarantee that therefore heat-carrying agent stream is only by built-in valve control.This can cause the undesired temperature control characteristic of user.

Summary of the invention

The present invention is based on following task: guarantee only to carry out the control of heat-carrying agent by built-in valve.

Utilize the multi-plate radiator of mentioning in the foreword, this task is by following realization: sealing ring is arranged in the groove, the extending axially greater than its radial thickness of sealing ring.

Utilize this sealing ring, prevent heat-carrying agent, be generally hot water, can pass through adapter sleeve, promptly arrive second fin and without built-in valve from first fin.Sealing ring leans against on the radially inner side of adapter sleeve and on the radial outside of at least one fin, and seals in two positions.Thereby guarantee: if the valve element is mentioned from the valve seat of built-in valve, heat-carrying agent only can pass through built-in valve.This is a straightforward procedure of guaranteeing can not take place internal leakage.The sealing circle is relatively easily installed.Because the design of its geometry has relatively little radial thickness, it can slip over one of two screw threads and not because of contacting screw thread or damaging because of excessive expansion thereby the sealing circle can expand between erecting stage to a certain degree.When sealing ring arrives groove, it will be released, thereby be maintained on the adapter sleeve in the mode of constraint.This has simplified assembly work considerably.When multi-plate radiator was mounted, two fin were by axially fastening from the outside along the direction of sealing ring.As long as a Contact Seal ring in two fin just can be realized the tight of needs, promptly heat-carrying agent can not flow through the gap between adapter sleeve and two fin, thereby enters second fin in uncontrolled mode.

Preferably, sealing ring has the radially-outer surface on plane.In the ideal case, the cross section of outer surface is the plane.Yet this not necessarily.Planar outer surfaces guarantees that sealing ring (it only is intended to seal between adapter sleeve and one or two fin) breaks away from from hermetically-sealed construction (it is intended to make two connections between the fin with respect to environmental sealing), and promptly sealing ring never influences hermetically-sealed construction.Hermetically-sealed construction and sealing ring can and can be adjusted to be used for their special application purposes by independent step manufacturing then.

Preferably, sealing ring has rectangular cross section.Thereby general plane is also made in the bottom side.In the case, term " rectangle " does not should be understood to the split hair implication of this speech.The uneven slightly surface of the rounding of fringe region or radial outside and/or radially inner side also allows, and is no problem.The sealing ring of essentially rectangular is made easily and is installed.

Preferably, between sealing ring and hermetically-sealed construction, provide radial distance.Thereby, guarantee that under any circumstance hermetically-sealed construction is not influenced by sealing ring between erecting stage.

Preferably, sealing ring has and extends axially, and it is greater than the distance of following two the phase double threads of fin confined state.Thereby it is guaranteed: in the axial direction, sealing ring leans against the starting position of at least one phase double thread, and it can provide seal point herein, when finishing the installation of adapter sleeve.This situation does not consider to install the mode of adapter sleeve.Usually, it can not calculate to a nicety, i.e. groove and sealing ring residing position in multi-plate radiator.The axial error of several millimeters scopes is possible.This is caused by the following fact usually: initial, adapter sleeve engages a fin, and it is fixed by rotation for several times herein, is established to the connection of other fin then.In the case, sealing ring will at first lean against on described first fin usually.

If sealing ring axially leans against at least one groove walls, also be favourable.This groove walls can apply axial compressive force then on sealing ring, thereby it leans against on the regional relative axial opposed end with the fin that can get herein to produce the needed power of tight ness rating.

Preferably, sealing ring filling groove in axial direction.In the case, do not need the displacement of sealing ring in groove between erecting stage, there is very little risk in this feasible damage.

If adapter sleeve is screwed in the vertical tube of two fin, this also is favourable, and this vertical tube has the inclined-plane on their inboard, and sealing ring leans against at least one inclined-plane.The inclined-plane for example can partly be formed by the beginning of single phase double thread.The inclined-plane forms inclined surface, and when it contacted with the inclined-plane, sealing ring radially compressed with axial direction to a certain extent by inclined surface.This provides big relatively sealing surfaces, and wherein sealing ring is applied with sufficient power.This has improved internal tightness.

Description of drawings

Below, with reference to the accompanying drawings, based on preferred embodiment explanation the present invention, show:

Fig. 1 has shown the cross section of the part of multi-plate radiator; With

The specific embodiment

Multi-plate radiator 1 has

first fin

2 and 3, two fin of

second fin

2,3 and is connected to each other by adapter sleeve 4.

First fin 2 has first vertical tube (standpipe) 5 and second vertical tube 6.Fin 3 has first vertical tube 7 and second vertical tube 8.In the mode that does not show in detail, other fin can be connected to second vertical tube 8.

Adapter sleeve 4 has: left hand thread 9, and it engages the phase double thread 10 of the correspondence in second vertical tube 6 of first fin 2; With right-handed thread 11, it engages the phase double thread 12 of the correspondence in first vertical tube 7 of second fin 3.Be rotated when adapter sleeve 4 for example applies surface 13 instrument by engage torque, two

fin

2,3 are drawn along direction each other.About this point, the hermetically-sealed construction between two

vertical tubes

6,7 distolateral makes connection between two

fin

2,3 with respect to environmental sealing.

First fin 2 is made for water inlet pipe, and by described water inlet pipe, heat-carrying agent, for example hot water flow into along the direction of arrow 15.In order to control heat-carrying agent, the built-in valve 16 with valve element 17 and valve seat 18 is set.By split ring (opening spring) 19, the valve element pushes away from valve seat 18.The actuator pin 21 that closing force can be from the outside be passed stuffing-box 20 via guiding applies, and pin 21 acts on valve element 17 via push rod 22.Usually, actuator pin 21 is activated by the constant temperature top.

Built-in valve 16 has valve shell 23, and it is screwed in the adapter sleeve 24.Adapter sleeve 24 is screwed into the screw thread 25 in first vertical tube 5 of second fin 2.

Built-in valve 16 has traffic probe structure 26, and its tubulose extends 27 and arrives adapter sleeve 4.Traffic probe structure 26 is used to guide the heat-carrying agent of inflow to pass through valve seat 18 to valve element 17 from first fin 2, and the heat-carrying agent in built-in valve 16 the place aheads is separated with the heat-carrying agent at built-in valve 16 rears.Via side entrance 28, heat-carrying agent can enter access road 29, and it can arrive distributor chamber 30 via the gap between valve element 17 and the valve seat 18 therefrom.From here, heat-carrying agent can flow through adapter sleeve 4 to second fin 3.Tubular extension 27 is by seal 31 relative adapter sleeve 4 sealings.

In order to prevent that heat-carrying agent from flowing through built-in valve 16 from first fin 2 and arriving second fin 3, adapter sleeve 4 has groove 32 between left hand thread 9 and right-handed thread 11.Be furnished with sealing ring 33 in groove, it forms the distance 34 that radially arrives hermetically-sealed construction 14.Sealing ring 33 has the essentially rectangular shape of cross section.In axial direction, its filling groove 32.It extends axially greater than its radial thickness.Thereby, Expansion sealing circle 33 and make it slip over left hand thread 9 or right-handed thread 11 and enter groove 32 to a certain extent between erecting stage.Herein, sealing ring 33 will discharge and be fixed on then in the groove 32 once more.

Sealing ring 33 is made by elastomeric material, and the heat resistance of this material is up to 100 ℃.Except rubber, also can be EPDM herein.

Between erecting stage, thereby lean on mutually each other by hermetically-sealed construction 14 when adapter sleeve 4 has been screwed into to a certain degree two fin 2,3, sealing ring 33 will lean against on the inclined-plane 35 in the fin 2 or on the inclined-plane 36 in the fin 3.Also can be that sealing ring 33 will lean against inclined-

plane

35,36 on both.Yet it will be enough leaning against in the inclined-

plane

35,36, because this also guarantees not have heat-carrying agent to overflow between adapter sleeve 4 and vertical tube 6,7.Inclined-

plane

35,36 can partly be formed by the beginning of phase double thread 10,12.Inclined-

plane

35,36 also makes sealing ring 33 press to the bottom of groove 32, therefore also can realize the tight ness rating that needs herein.Heat-carrying agent can not be overflowed between adapter sleeve 4 and sealing ring.
