Description

The thermostat valve of heater unit

Technical field

The present invention relates to a kind of thermostat valve of a kind of valve, particularly heater unit, this valve has a valve body, an operation bolt and a protective cap, and this valve body has the fixedly physical dimension of an operation lid.

Background technique

This operation lid is controlled this closing element with respect to the position of this valve seat and the amount of control heating liquid thus by this bibcock, heating liquid with the valve control flows through radiator.So need be fixed to the operation lid on the valve by a fixing device.Commercially available in the market most of valves all have fixing device as illustrated in fig. 1 and 2.On connection set shown in Figure 1 100, be provided with a faying surface 200, the base of the operation that is not shown specifically lid imports into axially by a radial force that is pressed onto fastening 300 of taper and is forced on this faying surface.The distance that faying surface 200 and being used for is operated between the free end of bibcock 400 of closing element is about 30 millimeters.A relevant example can be referring to DE 3236372 C2.

In a kind of connection set 500 with second kind of pattern shown in Figure 2, on fastening 700 the end face that constitutes as screw thread, be provided with faying surface 600.Locking nut with inward flange can be pressed onto the base of operation lid on the faying surface 600 by screwing on.Be about 10 millimeters apart from B between the free end of faying surface 600 and bibcock 400.A relevant example can be learnt from DE 4344773 A1.The difference of other connection set and connection set 500 is, apart from B greatly, for example is about 20 millimeters.

In addition, DE 9411056 U1 have proposed the valve with a kind of operation lid of suitable two or more models of connection, and it is that an adapter is realized by connect an ABAP Adapter between valve and operation lid.So heater unit miantainers when place under repair, only need get final product with the last spare part that he must carry.He also can combine valve and operation lid that different manufactories produce.But the fact shows that unwanted annex or ABAP Adapter but often can not find in the moment of needs when certain usage mode, as being lost or using up.

Summary of the invention

The objective of the invention is to, propose a kind of valve of the above-mentioned type, this valve possesses whole means, so that a kind of in the operation lid of at least two kinds of different models selectively is installed.

Concerning aforementioned that class valve, this purpose is achieved in that to be that at least a portion of protective cap is designed to ABAP Adapter, this ABAP Adapter have one with the coefficient tappet of operation bolt.

Generally when for the first time being installed to valve on the radiator, or valve had been packed into the situation of radiator by manufacturing firm under, when radiator was installed, valve must match with a kind of operation lid of regulation model.But to this constantly, valve generally still is being with protective cap, and the basic task of protective cap is that Protective valve especially protects the operation bolt to avoid damage in transportation process.This protective cap but at the latest after loading onto the operation lid, is taken as waste product and throws away after having carried out installing.When needing, protective cap can partly have two purposes at least, and a purposes is known, promptly in transportation process valve is protected; Another purposes is, when a kind of operation lid that needs another kind of fixedly physical dimension on valve body will be installed, at least a portion of protective cap can be used as the ABAP Adapter use.

This double duty of protective cap is many known, and for example DE 29708193 U1 have just pointed out to come with protective cap the possibility of preconditioning valve.

ABAP Adapter preferably is connected with a threaded collar that is contained on the valve body outside thread.As mentioned above, this outside thread is used for fixing a kind of operation lid of model.Outside thread constitutes the fixedly last section of physical dimension in the direction of radiator, makes the protected cap of holding part size cover fully.So it is very big that protective cap becomes, only need to constitute ABAP Adapter with its part.This ABAP Adapter can be taken off from threaded collar simply, when protective cap also is fixed on the valve, can take off ABAP Adapter.In this case, when this ABAP Adapter installs on the valve, just drawn the predetermined location of this ABAP Adapter on valve, so wrong danger of installing is minimum.Certainly, also can take off this protective cap and separate this ABAP Adapter from valve from threaded collar.

ABAP Adapter preferably has a root elevator bar, this tappet and operating stem acting in conjunction, and wherein this tappet is furnished with a loss prevention device.That is as long as protective cap is loaded on the valve, this tappet just can not lost.But as the ABAP Adapter time spent, this ABAP Adapter still can enough move in the part of protective cap, so as under the effect of operation lid the operation bolt of removable valve.

ABAP Adapter preferably is fastened on the threaded collar by draw-in groove.This means of fixation is enough firm, so protective cap can be finished its protective function.Simultaneously this draw-in groove connects also available not too big strength and unclamps, so ABAP Adapter can be taken off from threaded collar easily.

In this case, with less power just can unclamp this draw-in groove connection towards an end of valve body side when moving to another way in ABAP Adapter, this is particularly advantageous.So just determined a preferred orientations.At this moment this ABAP Adapter can only promptly be unclamped from threaded collar towards the direction of valve body in certain direction.So prevented effectively that unconscious mistake from unclamping.This is fixed on the valve in ABAP Adapter, and threaded collar is particularly advantageous when still being fixed on the outside thread.

In a kind of preferred design proposal, this threaded collar is mitriform and is enclosed in away from the end of valve body and have an engaging hole of instrument.In this case, the ABAP Adapter under the tight condition is actually and can not lose.But engaging hole must allow with instrument this ABAP Adapter to be backed out from threaded collar.The working length of instrument can be quite short.ABAP Adapter moved to unclamp draw-in groove and connect and to get final product.

ABAP Adapter is connected with the most handy buckle ways of connecting of valve body, like this, just realized quite simply being connected of ABAP Adapter and valve body.General only the need can realize between ABAP Adapter and valve body that once a pressure or a blow draw-in groove connects gently.

In this case, particularly advantageous is that ABAP Adapter has a chucking lug boss, and this lug boss is engaged on a back that embeds the ring in the valve body.Draw-in groove connects only to be needed firmly to be operated to cover to be pressed into to the operation bolt that can make valve to get final product.Here generally need overcome the power of a spring.In addition, also has the pressure of heating liquid effects to the closing element.Such power can be subjected to by this rim bearing.But when ABAP Adapter when valve body takes off, this ring preferably can be destroyed falls.Just avoided ABAP Adapter and valve body to sustain damage in this case.If this ABAP Adapter will be reused, then only need encircle or ring that one new embeds ABAP Adapter and valve body are tightened.

In another kind of design proposal, ABAP Adapter can be connected with threaded collar by at least one theoretical point of rupture.Protective cap is generally made of plastic.Like this, the connection part between threaded collar and ABAP Adapter can be done quite thinly, so by firmly making this place's fracture once pressing.In this case, ABAP Adapter and threaded collar constitute the attachment portion of a unique easy manufacturing.ABAP Adapter is fixed in the threaded collar reliably and can not be lost, and protective cap does not sustain damage.It is also quite easy that ABAP Adapter is unclamped from threaded collar.

Tappet preferably is connected with ABAP Adapter by at least one theoretical point of rupture.Connection between tappet and the ABAP Adapter is identical with the connection between ABAP Adapter and the threaded collar.

ABAP Adapter preferably ° is fixed on the valve body at the position Rotate 180 on the whorl with respect to it.In this case, the appearance of ABAP Adapter is more flexible.When protective cap was downloaded on the valve, ABAP Adapter needn't be placed on the inside of protective cap.This has just made things convenient for the multiple possibility of appearance.

Embodiment

Fig. 3 a represents a valve 11 with the valve body 12 that schematically illustrates.An operation bolt 4 or rather, leads by a stuffing box 14 or a similar seal element by valve body 12.Operation bolt 4 is connected this valve element and valve seat 16 actings in conjunction with a valve element 15.Valve element 15 has carried out preload in opening direction, so valve 1 is controlled like this, promptly operation bolt 4 is pressed in the valve body 12 more or less.

Valve 11 is furnished with a protective cap 17, in order to avoid valve 11 for example sustains damage in transportation process and in the environment that produces strong load on-site.Fig. 3 b represents the perspective view of this protective cap, and this protective cap is tightened on the outside thread 7 of valve body 1, and this outside thread can be as can be seen from Figure 2.Outside thread 7 constitutes fixing device shown in Figure 2 with the step and the faying surface 6 of this valve body, wherein faying surface 6 and the operation bolt 4 free end between be about 10 millimeters apart from B.That is when valve body 12 is backed out protective cap 17, then fixing device shown in Figure 2.

But in some situation, need one of configuration to be equivalent to fixing device shown in Figure 1.In order to change valve 11 like this, make it to accept this pattern, then need to use the part of this protective cap.

Protective cap 17 mainly is made up of three parts, that is: one is tightened in the threaded collar 18 on the outside thread 7, an ABAP Adapter 19 and a root elevator bar 20.

ABAP Adapter 19 connects 21 by a draw-in groove and is connected with threaded collar 18.For this reason, this ABAP Adapter has radially outer tooth 22, and this tooth is engaged in the radially uncovered inwards groove 23.Tooth 22 also can make closed annular protrusion, and groove 23 is then equally around circumferencial direction.In this case, the flank of tooth 24 of the tooth 22 of sensing valve body 12 is much milder than the flank of tooth 25 on opposite, so only may extrude ABAP Adapter 19 from threaded collar 18 in the direction of valve body 12.This extrusion can be carried out in a position of threaded collar 18 screw-in valve bodies 12, but also can screw out protective cap 17 from valve body 12 fully, extrudes ABAP Adapter 19 from whorl 18 then.

As long as protective cap 17 is tightened on the valve body 12, tappet 20 is not lost with regard to remaining in the protective cap 17.Shown in Fig. 3 c, the inside in the space of defining by ABAP Adapter 19, tappet 20 has a those widened sections 26.This those widened sections 26 is like this designs, and promptly at tappet 20 during with respect to ABAP Adapter 19 (or opposite) half-twist, this those widened sections is engageable in a space 27.And in the position shown in Fig. 3 a, 26 of those widened sections are close on the inboard of ABAP Adapter 19.In aspect the drawing plane (with respect to Fig. 3), the extension in space 27 is less than the width that can find out among the figure, so tappet 20 is close on the ABAP Adapter 19 from the inside with its those widened sections 26 in the rotational position shown in Fig. 3 a.Can be pressed onto ABAP Adapter 19 on the valve body 12 by space 27, and not exist tappet 20 operation bolt 4 to be pressed into the danger of valve body 12.

Only schematically show among the figure on the torsional interaction face 28 of valve body part that ABAP Adapter 19 acts on an activity, so that carry out the preconditioning of valve 11 with this part.

If still be unkitted the operation lid, then protective cap 11 also can be used to for example regulate on-site radiator valve, does not intend here giving unnecessary details.

From Fig. 3 c as can be seen, this ABAP Adapter has a chucking lug boss 29 in its side towards valve body 12, and when ABAP Adapter 19 moved to valve body 12, this lug boss can mesh with ring 30.Ring 30 is arranged in the groove 31 of this valve body.In ring 30 back, in moving direction, have one to receive space 32, when ABAP Adapter 19 when valve body 12 motions reach the location, this chucking lug boss 29 can enter in this space.

Ring 30 is designs like this, and promptly it can hold out against the whole power of valve 11 in normal generation in service, and ABAP Adapter 19 does not rise from valve body 12.But when obviously bigger masterpiece was used on the ABAP Adapter 19, then ABAP Adapter 19 also may be pulled out from valve body 12.In this case, encircle 30 destroyed or be damaged.But this is unimportant, is as throwing away the part design because encircle 30.Can be with in new ring 30 embedded grooves 31, valve body 12 can be used to mounting adapter 19 again.

Fig. 3 d represent that ABAP Adapter 19 has been contained on the valve body 12 and with the situation of its chucking.The those widened sections 26 of tappet 20 has entered in the space 27.Chucking lug boss 29 has been clamped on the back of ring 30.Fixedly physical dimension shown in Figure 1 so just is provided, especially can have known and see conical surface 3.Distance between the upper end of stationary plane 2 and tappet 20 is about 30 millimeters.

ABAP Adapter 19 has a groove 31 at its end towards valve body 12 in an annular flange flange 35, when ABAP Adapter 19 was close on the valve body 12, the lug boss 33 of a pin shape of valve body was engaged in this space.By the acting in conjunction generation anti-torsion effect of lug boss 33 with groove 31.Annular flange flange 35 is formed in the main faying surface of the ABAP Adapter 19 on the valve body 12, and for this reason, this valve body has the lug boss 34 of a ring-type, and this lug boss surrounds receiving space 32.

As shown in the figure, when threaded collar 18 screwed in valve body 12, ABAP Adapter 19 can extrude from whorl 18.In this case, automatically draw the orientation of the ABAP Adapter 19 of requirement to valve body 12.But also can screw off threaded collar 18 from valve body 12 at first fully, take off ABAP Adapter 19, then ABAP Adapter 19 and valve body 12 lockings.

Fig. 4 represents a kind of similar structural type, and the wherein identical part identical with function still continued to use identical reference character.In this case, only schematically show valve body 12.

Protective cap 17 is its upper end of bell sealing promptly away from an end of valve body.Correspondingly, ABAP Adapter 19 is extruding from threaded collar 18 in the direction of valve body 12 only.Upside 36 to the sealing of the protected cap 17 of the motion of another direction stops.In order to operate ABAP Adapter 19, be provided with unique engaging hole 37, can insert a for example instrument of screw wrench and so on by this hole, ABAP Adapter 19 is back-outed and unclamped draw-in groove from threaded collar 18 connects 21.

In this embodiment, the root of ABAP Adapter 19 illustrates in figure, also can make into to shift onto simply on the valve body 12.In case of necessity, also additional fixing device can be set, for example radially protruding inwards lock projection portion or thread engagement.

Fig. 5 represents the third structure of valve, and this valve can be transformed into a kind of fixedly physical dimension shown in Fig. 5 d from a kind of fixedly physical dimension shown in Fig. 5 a with protective cap 17 (Fig. 5 b).

For this reason, protective cap 17 still has whorl 18, and this whorl is connected with ABAP Adapter 19.Whorl 18 screws on the outside thread 7 of the valve body 12 that equally just illustrates.

ABAP Adapter 19 is connected with threaded collar 18 by a theoretical point of rupture 38.Threaded collar 18 and ABAP Adapter 19 can be used as overall structure and make, and for example pass through injection-moulding plastic.Theoretical point of rupture 38 is made the material position of having reduced material thickness.Tappet 20 is pressed similar manner by a theoretical point of rupture 39 and is connected with ABAP Adapter 19.Shown in Fig. 5 e, when ABAP Adapter 19 installed on the valve 12, it was rotated 180 °.
