Description
Technical field
The present invention relates to a kind of defroster that prevents that water supply pipe etc. from sending the water in the water pipe arrangement to freeze.
Background technology
In the past, propose a kind of not serviceability temperature sensor etc., and utilized the physical property of water just can prevent the defroster that freezes (spy opens flat 8-28732 communique) of waterpipe reliably.Fig. 7 represents an example of this defroster.
In the drawings, the 40th, send the water pipe arrangement, the 41st, with the main body of sending water pipe arrangement 40 to be connected, the 42nd, be fixed on the sleeve pipe of main body 41 inside with one heart.Between main body 41 and sleeve pipe 42, be formed with service depot 43 cylindraceous.Valve body 44 comprises the 44b of valve portion of formed valve port 45 on the sealing 44a of the upper end that can seal service depot 43 and the switch main body 41 with being free to slide.
If, then open valve port 45 by volume expansion effect jack-up valve body 44 owing to the decline of outside air temperature makes the water-setting in the service depot 43 solid.Because the valve events of opening by this valve body 44 makes the water that send in the water pipe arrangement 40 by the drainage channel 46 in the sleeve pipe 42, so the ice of potentiality heat in sleeve pipe 42 dissolves service depot 43 of this water.Like this, the smaller volume of service depot 43 can make valve body 44 close.That is, because the potentiality heat by the water that flows in drainage channel 46 makes the ice dissolving service depot 43 in, so even, reach conserve water in cold period also valve body 44 at short notice.
The defroster of said structure, because of valve port 45 being formed on the cause of main body 41 inside, and main body 41 is made of connector portions 41a and two parts of the 41b of cylinder body portion, and valve body 44 also is made of 2 parts.That is, being supported on the 44b of valve portion above the valve port 45 and the sealing 44a of slip service depot 43 in is separated up and down.The axial region 44c that is integrally formed on the sealing 44a connects valve port 45, is screwing togather the 44b of valve portion in the top.Like this, the structure that exists main body 41 and valve body 44 becomes complicated, on assembling operation, take time and energy, and the problem that causes cost to rise.
In addition, when valve body 44 is opened valve port 45, the water that send water pipe arrangement 40 by valve port 45, be located at drain hole on the axial region 44c, and sleeve pipe 42 in discharge.But a part of draining meeting accumulates in the downstream of valve port 45, for example, and between axial region 44c that accumulates at valve body 44 and the valve port 45 or between valve body 44 and the sleeve pipe 42.Because this part is opened in the atmosphere,, can hinders valve body 44 and successfully hold valve events so the water that accumulates freezes.
Summary of the invention
So,, also can not give and drive the defroster that valve events brings obstacle even the object of the invention is to provide a kind of designs simplification, is easy to assembling and a part of draining is freezed.
To achieve these goals, the invention provides a kind of defroster, this defroster is characterised in that, comprise: the main body of an end and the tubular of sending the water pipe arrangement to be connected, be fixed on the inside of described main body with one heart and send the end of water pipe arrangement side to be formed with the sleeve pipe of valve port at this, be formed between the outside of the inner face of described main body and sleeve pipe and internal storage has the service depot cylindraceous of water, one end has the sealing cylindraceous of the end of sending water pipe arrangement side that can seal described service depot with being free to slide, and the other end has the valve portion of the described valve port of switch, and the described relatively main body of volume expansion effect when solid and sleeve pipe axially slide and open the valve body of described valve port by the water-setting in the service depot, be discharged to outside drainage channel with the water that valve events will send water pipe arrangement inside opened from the inboard of described valve port by sleeve pipe by described valve body.
If the water-setting by the service depot produces volume expansion admittedly, then sealing service depot one distolateral valve body is axially pushed.Axial moving by this valve body opened valve port, will send the water of water pipe arrangement inside to be discharged to the outside from valve port by the sleeve pipe inboard.
If will send the water of water pipe arrangement inside to be discharged to the outside by drainage channel, the potentiality heat that then this water had reaches the service depot through valve body, main body or sleeve pipe, dissolves the ice of inside, service depot.Like this, the volume of service depot diminishes, and hydraulic pressure or the spring force etc. of valve body by sending the water pipe arrangement automatically closes valve.
Because the service depot is formed between the main body and sleeve pipe into fixed part, it is distolateral that valve body can seal one with being free to slide, so the volume expansion pressure when water-setting is solid only axially acts on valve body, valve body can successfully axially be moved, can realize the sensitive valve events of opening.
Valve port is not formed on the main body, and is formed on the end of sending water pipe arrangement side of the sleeve pipe of the inwall that constitutes the service depot.Like this, when valve port is opened, water only from valve port by discharging the sleeve pipe.That is, because on the drainage path in valve port downstream, there is not the sliding part of valve body, so, bring harmful effect can for the valve events of holding of valve body even a part of draining is freezed in sleeve pipe yet.
In addition because valve port be formed on sleeve pipe send water pipe arrangement side end, so need not as the situation that forms valve port on main body main body to be processed into complicated structure, also available 1 parts constitute.Like this, Miniaturizable simple in structure.
The present invention's 2 described defrosters, preferably valve body is formed with slightly being of the end tabling that send water pipe arrangement side of described sleeve pipe and cover shape, the valve gasket of switch valve port is installed on the medial surface of valve portion, in the centre of described valve portion and sealing, be provided with the intercommunicating pore that is connected in inside and outside week that makes valve body.
Like this, cover shape because if valve body formed with slightly being of end tabling of sleeve pipe, a then available body component constitutes sealing and valve portion, so structure becomes simple further miniaturization.In addition,, the assembling of valve body gets final product, so that assembling operation becomes is easy because also only being entrenched in the end of sleeve pipe.
The present invention's 3 described defrosters, the end that preferably forms the side opposite with sending water pipe arrangement side make the described inside of sending the water pipe arrangement and described service depot on described main body are connected and freeze earlier and the inflow path that seals than the service depot.
Be necessary all the time water abrim in the service depot, but if because of certain reason enters air, though then water to freeze also only be that air is compressed, and can not open valve body.At this, owing to be provided with from sending the inflow path of water pipe arrangement, so water is full of the service depot all the time to service depot's supply water.
Flowing into path must freeze earlier and seal than the service depot, and in addition, the ice that flows into path when draining does not dissolve for good.Because if the service depot freezes earlier, then the part of its volume expansion also can be discharged through flowing into path, so need not open valve body.In addition, because if flowing into the ice of path during draining dissolves earlier, then the volume expansion pressure of service depot shifts through flowing into path, before the ice of service depot dissolves with regard to valve body.Because inflow path, the end of a side opposite with sending water pipe arrangement side of the inside of sending the water pipe arrangement and service depot is connected, freeze earlier than the service depot so flow into path, and evening time that the ice of the time ratio service depot that the ice that flows into path dissolves is dissolved.
Simultaneously, flow into path, but also one is located on the sidewall of main body, or also can uses tubule will send the water pipe arrangement to be connected in the outside of main body with the service depot.
The present invention's 4 described defrosters preferably on the sidewall of main body, but are installed the breather valve of free switch air vent.
As mentioned above, be provided with under the situation that connects the inflow path send water pipe arrangement and service depot, because residual air in the service depot sometimes, air is a compressible fluid, so the valve events of opening of valve body is delayed.At this, if the present invention's 4 described air vent and breather valves are set, then when opening breather valve, owing to the interior drops of service depot, so send the water in the water pipe arrangement to import the service depot from downside (end of a side opposite) with sending water pipe arrangement side by flowing into path.Thereupon, the water in the service depot is discharged from by air vent, but owing to the air that accumulates the top (sending water pipe arrangement side) in the service depot is simultaneously also discharged with water, so can discharge the residual air of service depot effectively.
The present invention's 5 described defrosters, valve body, the hydraulic pressure by water mobile in sending the water pipe arrangement comes valve portion is pushed along the direction of close port.Like this, the ice one of service depot dissolves, and valve portion is close port promptly just, can prevent that water from discharging in vain.
The present invention's 6 described defrosters, be provided with the spring that makes valve portion push valve body along the direction of close port, even then be difficult to along the situation of closing the action of valve direction because of certain reason valve body, making a concerted effort of the hydraulic pressure that also can be by the water that in sending the water pipe arrangement, flows and the elastic force of spring, make valve body close port reliably.

The specific embodiment
Fig. 1～Fig. 5 is the embodiment of expression defroster A of the present invention.
In water supply pipe etc. send the way of water pipe arrangement 1, connect T shape shaft coupling 2, on the connector 2a of the bottom of this shaft coupling 2, be connected with the cylindrical-shaped main body 3 of defroster A.Pipe arrangement 1, shaft coupling 2 and main body 3 screw togather by tapered thread 1a, 2b, 3a, and realize mutual sealing.
The upper end open portion place of the main body 3 in being inserted into the connector 2a of shaft coupling 2 is equipped with spring support 5 by lock ring 4.Spring support 5 is supporting an end that makes valve body 20 described later trend towards closing the backspring 27 of valve direction, the aperture 5a of the flow when heart portion is formed with and is used to adjust valve body 20 and opens therein.
Near the upper end open portion of main body 3, be formed with the valve chamber 3b that bloats laterally, this valve chamber 3b is connected with the inside of sending water pipe arrangement 1 by the aperture 5a of spring support 5.The valve portion 24 that is located on valve body 20 tops is arranged in valve chamber 3b.In main body 3 inside, be inserted with slightly columnar sleeve 10 from the below, be arranged on the outward flange dish 10a of the bottom of sleeve pipe 10, by with the bottom inner face that is formed on main body 3 on following relative the fetching of inner flange 3c position.Screwing togather locking nut 16 in the bottom of main body 3, by this locking nut 16, through the flange of resinous hose coupling 17 make the flange 10a of sleeve pipe 10 compress main body 3 inner flange 3c below.In view of the above, sleeve pipe 10 is fixed on main body 3 inside with one heart.
Between the outside of the inner face of main body 3 and sleeve pipe 10, be formed with the service depot cylindraceous 6 of internal storage water.The lower end side of service depot 6 (side opposite with sending water pipe arrangement side), the seals 11 such as O shape circle on the excircle of the outward flange dish 10a by being installed in sleeve pipe 10 carry out airtight.Between the outward flange dish 10a of the inner flange 3c of main body 3 and sleeve pipe 10, be formed with circlet shape space 13, annulus 13 and service depot 6, the 2nd ostium 14 by up/down perforation inner flange 3c is communicated with.Annulus 13 is connected with the valve chamber 3b of main body 3 by flowing into path 7.Inflow path 7 is formed on the inside with the outside wall portions of main body 3 convex strip portions 8 (with reference to Fig. 2) integrally formed, that axially extend.In this embodiment, flow into path 7 and be formed with the through hole that axially connects for convex strip portions 8, its lower end is sealed with set bolt 15, and between annulus 13 and through hole, be formed with the 1st ostium 19 of inclination.
The upper end of sleeve pipe 10 extends to the valve chamber 3a of main body 3, is formed with the valve port 12 that has dwindled diameter a little in this upper end.As shown in Figure 3, in the upper end of above-mentioned sleeve pipe 10, axially move freely the valve body 20 of ground chimeric lid shape.In the bottom of valve body 20, be formed with the columnar sealing 21 that the upper end side to service depot 6 seals.In the interior periphery of sealing 21, be equipped with the contacted O shape circle of the outer peripheral face of sleeve pipe 10 wait seal 22 and with the contacted seal 23 of the inner peripheral surface of main body 3.In the upper end of valve body 20, be provided with valve cylindraceous portion 24, the inside top surface place in this valve portion 24 is equipped with the valve gasket 25 of the above-mentioned valve port 12 of switch.Between the valve portion 24 and sealing 21 of valve body 20, be provided with the intercommunicating pore 26 that is communicated with outer peripheral face and inner peripheral surface, the water in the valve chamber 3b is conducted to the outer peripheral face of sleeve pipe 10 (valve port 12) all the time by this intercommunicating pore 26.In this embodiment because valve port 12 is slightly littler than the diameter of sleeve pipe 10, so between the outer peripheral face of the inner peripheral surface of valve portion 24 and valve port 12, be formed with annulus 9 (with reference to Fig. 4), in this annulus 9 by intercommunicating pore 26 importing water.On the valve portion 24 of valve body 20 and between the spring support 5, dispose valve body 20 application of force and pad 25 is against the backspring of using on the valve port 12 27 downwards.In this embodiment, set the load on spring of backspring 27 lowlyer, for example, even when defroster A send water pipe arrangement 1 along inclined direction to install relatively, valve body 20 also can play installs the ground supporting roles to valve port 12 is stable.
In this embodiment, because valve port 12 is formed on the upper end of sleeve pipe 10, thus the upper end open portion of covering valve body 20 autonomous agents 3 of shape can be inserted, and only assemble with the upper end tabling of sleeve pipe 10, assembling becomes simple.In addition, because need not on main body 3, to form valve port, the simplification so the structure of main body 3 becomes, its result has and can be respectively constitutes valve body 20 and main body 3, makes the advantage of valve body 20 and main body 3 miniaturizations with 1 parts.
In the inside of sleeve pipe 10, the resin system of pegging graft gutter (drainage channel) 29.When valve body 20 is opened valve port 6, send the water in the water pipe arrangement 1 to pass through valve chamber 3b, intercommunicating pore 25, valve port 12, gutter 29, the hose coupling 17 of the inside through being plugged on sleeve pipe 10 are discharged to the outside.Thereby, form drainage channel by gutter 29 and hose coupling 17.Gutter 29 and hose coupling 17 in water pipe arrangement 1 is sent in discharge during water, can prevent that water droplet from freezing on the inner face attached to sleeve pipe 10, and the resin material of poor thermal conductivity such as handy polyflon forms.Like this, the potentiality heat of water is difficult to reach sleeve pipe 10 during draining, but as described later, only water-solubleization in the service depot 6 just closed valve, so the almost influence that is not produced by gutter 29.Simultaneously, as required, also can omit or set shortly, and draining is flowed along the inner face of sleeve pipe 10 gutter 29 than illustrated.
The material that main body 3 the most handy heat biography rates as brass are high forms.Like this, when outside air temperature reduces, flow into of the external surface diffusion of the potentiality heat of the water in path 7 and the service depot 6, the water that flows in path 7 and the work grease chamber 6 is promptly solidified from the main body 3 that constitutes outer wall.And, because service depot 6 is made of the cylindric space of thin-walled, thus big with respect to the contact area with main body 3 of volume, can be promptly to external world temperature react.
On the other hand, the valve body 20 the most handy materials lower than main body 3 pyroconductivities (for example, stainless steel) form.That is, when valve body 20 is also identical with main body 3 when forming with the high material of pyroconductivities, the potentiality heat of the water of valve chamber 3b inside reaches service depot 6 by valve body 20, might make the set retardation of the water of service depot 6.Otherwise, if being compared the low material of pyroconductivity with main body 3, valve body 20 usefulness form, then tail off through the heat that valve body 20 reaches service depot 6 from valve chamber 3b, and the water in the service depot 6 is promptly solidified.
In addition, the also available material lower than main body 3 pyroconductivities of sleeve pipe 10 (for example, stainless steel) forms.Its reason be because, the heat of air layer that suppress to constitute sleeve pipe 10 inboards of service depot's 6 inwalls reaches service depot 6, can prevent to delay the solidifying of water in the service depot 6.But it is self-evident that sleeve pipe 10 also can form with the high material of pyroconductivity in the same manner with main body 3.
On the sidewall of the main body 3 that is positioned at 6 tops, above-mentioned service depot, be formed with that medial end communicates with the outer peripheral face of the sealing 21 of valve body 20, the air vent 30 of outboard end and exterior.On the outboard end of air vent 30, be formed with box thread 31, but screwing togather the breather valve 32 of free switch air vent 30 on this box thread 31.On breather valve 32, be formed with the water that to flow in the air vent 30 and be discharged to outside tap 33.At the leading section of breather valve 32, the seal (O shape circle) 34 of sealing air vent 30 is installed.
Owing to a dozen open air valve 32, the pressure in the service depot 6 just descend, so send the water in the water pipe arrangement 1 to pass through valve chamber 3b, flow into path 7, import service depot 6 from the below.Thereupon, the water in the service depot 6 from the outer peripheral face of valve body 20 and the gap of main body 3, discharge through the tap 33 of air vent 30 and breather valve 32, but the air that accumulates 6 tops in the service depot is simultaneously also discharged with water.Because air is compressible fluid, so as if the residual a spot of air of meeting in service depot 6, the valve events of holding of valve body 20 is obviously delayed, but as mentioned above, because flowing into path 7 is connected with the foot of service depot 6, air vent 30 is connected with the topmost of service depot 6, so can discharge the residual air of service depot 6 effectively.
Below, the course of work of the defroster A of above-mentioned formation is described.
If outside air temperature is reduced to subzero, the potentiality heat that then flows into the water in path 7 and the service depot 6 is emitted through main body 3, and the water that flows into path 7 at first freezes, and the water in the service depot 6 begins to solidify again then.Especially, because the influence of the potentiality heat of the water of valve chamber 3b inside, so compare with the top near valve chamber 3b in the service depot 6, lower side is solidified soon.If the water in the service depot 6 begin to solidify, then because flowing into path 7 has freezed and be closed, so the volume expansion when solid by the water-setting of service depot 6, jack-up valve body 20 is opened valve port 12 (with reference to Fig. 5).Like this, send the water in the water pipe arrangement 1 to be discharged to the outside by valve chamber 3b, valve port 12, gutter 29.Its result can promote to send the flowing of water in the water pipe arrangement 1 to prevent to send freezing of water pipe arrangement 1, and the potentiality heat of the water that is discharged from conducts to service depot 6 through main body 3, valve body 20 or sleeve pipe 10, and the ice in the service depot 6 are dissolved.Its result makes the volume-diminished of service depot 6, valve body 20 by sending water pipe arrangement 1 hydraulic pressure and the elastic force of spring 27 be depressed, automatically close valve.After, repeat above-mentioned action.
Open in the valve events above-mentioned,, only bear the direction of principal axis power that produces by the volume expansion of service depot 6, so that the direction of principal axis of valve body 20 moves is very well because valve body 20 is configured in the upper end side of service depot 6.Like this, cotton-shapedly just can drive valve as long as the water in the service depot 6 begins to be frozen into ice, the decline of temperature is quick on the draw to external world, can prevent to send freezing of water pipe arrangement 1 grade and other pipe arrangements reliably.In addition, when opening valve port 12 and carry out draining, because promptly dissolve cotton-shaped ice in the service depot 6 by the potentiality heat of draining, thus unnecessary water-white can not discharged in vain, and valve-off comes conserve water.
As mentioned above, because valve port 12 is formed on the upper end of the sleeve pipe 10 of the inwall that constitutes service depot 6, so when opening valve port 12, the water in the valve chamber 3b is only discharged by valve port 12.That is, the water by valve port 12 just is discharged from without the gap of valve body 20 and main body 3 or the gap of valve body 20 and sleeve pipe 10.In small-sized defroster, because the internal diameter of sleeve pipe 10 diminishes, so some draining accumulates in gutter 29, gutter 29 is opened in the atmosphere, so the draining that accumulates might be frozen.But, in the gutter 29 in the downstream of valve port 12, because there is not the sliding part of valve body 20, so, bring harmful effect also fully for the valve events of opening of valve body 20 even the draining that accumulates is frozen in gutter 29.
Simultaneously, because of the ice of forming in gutter 29, if open valve port 12 water of sending pipe arrangement 1 is flowed into, then moment will dissolve, so no problem.In addition, owing to use the little material of friction factor such as polyflon to be used as gutter 29, so the pressure differential when driving valve also can be discharged ice.
The upstream side of valve port 12 (valve chamber 3b, intercommunicating pore 26, annulus 9) because be connected with water supply piping 1, and is full of by the water with certain pressure, so can not freeze.
Fig. 6 is the additional embodiments of expression defroster of the present invention.
In the embodiment in figure 1, be formed on inside with the integrally formed convex strip portions 8 of the outside wall portions of main body 3 with flowing into path 7, but, in this embodiment, form and flow into path 7 by connecting the pipe of establishing in addition 18.Inflow pipe 18 is because be necessary to make inner water to freeze rapidly than service depot 6, so the good metal tube of the most handy thin-walled and thermal conductivity constitutes.In this case, because the whole periphery of inflow pipe 18 exposes in ambient atmos, so can freeze rapidly.
In the present embodiment, use tabular pad is used as being installed in the seal 34 on the breather valve 32.
In the embodiment in figure 1, because the bottom of annulus 13 and service depot 6 is connected, so be formed with the 2nd ostium 14 on inner flange 3c, but in the present embodiment, the gap between outer peripheral face by sleeve pipe 10 and the inner peripheral surface of inner flange 3c is communicated with.
Defroster A of the present invention is not limited to be installed in the situation in the way of sending water pipe arrangement 1 shown in Figure 1, and can be installed on all positions.For example, also can be installed near the turncock of pipe arrangement terminal part, or be installed on the pipe arrangement of water supplying apparatus.
In the above-described embodiments, the main body 3 of defroster A is made of the integrative-structure parts, but also can opens identical the constituting of flat 8-28732 communique with the spy by a plurality of parts.For example, if will constitute with miscellaneous part, even the different situation of the diameter of the connector of shaft coupling 2 is then also only changed joint and just can be carried out correspondence simply with the blank area that shaft coupling 2 is screwed.
In the above-described embodiments, shown inflow path 7 at first freeze be closed after, the water of service depot 6 solidifies again, make the example of valve body 20 actions, but also can adopt on inflow path 7 one way valve is set, do not freeze earlier even flow into path 7, can prevent that also the bulbs of pressure that produced by the solidifying of water of service depot 6 are transferred in the inflow path 7.
