Description
【Technical field】
The utility model is related to a kind of gas heater regulating valves.
【Background technology】
Or being electronically controlled gas ratio valve or being to use cylinder applied to the Air-regulating valves on gas heater at present
The water vapor linked valve that spool is adjusted.Although proportioning valve adjusting is relatively accurate, the additional segmentation solenoid valve valve of palpus could be realized
Same function；Water vapor linked valve, price is relatively low, but must an additional solenoid valve, pressure maintaining valve and segmentation solenoid valve
It could realize same function, existing these gas valves having are complicated, and manufacturing cost is high.
【Utility model content】
The purpose of the utility model is to overcome the deficiencies in the prior art, provide combustion gas heat a kind of simple in structure, at low cost
Hydrophone regulating valve.
To solve the above-mentioned problems, the utility model uses following technical scheme：
A kind of gas heater regulating valve, including valve body, the valve body are equipped with the first venthole and the second venthole,
It is axially distributed along the spool equipped with taper valve core, first venthole and the second venthole in the valve body,
It is characterized in that：The spool be equipped with the first spool bore for being connected to first venthole and with second outlet
Second spool bore of hole connection, first spool bore are circumferentially at least two in the spool.
A kind of gas heater regulating valve as described above, it is characterised in that：The first spool bore phase described at least two
It is gradually reduced and the first adjacent spool bore close to one the first spool bore and the communication port of the first venthole when valve core rotation is made
Gradually increase with the communication port of the first venthole.
A kind of gas heater regulating valve as described above, it is characterised in that：There are three first spool bore is set, institute
There are two the second spool bore stated is set.
A kind of gas heater regulating valve as described above, it is characterised in that：One in the first spool bore described in three
For macropore, two are aperture, and when the valve core rotation, two can be simultaneously in the first venthole for aperture；Two the second valves
Core bore one is macropore, and one is aperture, and macropore diameter is 2-10 times of aperture.
A kind of gas heater regulating valve as described above, it is characterised in that：The valve body is externally provided with mounting plate, described
Spool one end be pierced by from the mounting plate, motor is additionally provided on the mounting plate, is set on the motor shaft of the motor
There are driving gear, the traversing through end of the spool to be equipped with driven tooth block, be equipped between the driving gear and driven tooth block
The driving cog engaged with the two.
The beneficial effects of the utility model have：Since the first spool bore is equipped at least two, when rotational valve core, combustion gas is from cutting
Only state, one section of burning minimum load state, arrive continuously adjusting for peak load state again, to realize Discrete control, structure
Simply, production cost is low；At least two first spool bores are mutually close, such spool one first spool bore and first in rotation
The communication port of venthole is gradually reduced and the first adjacent spool bore and the communication port of the first venthole gradually increase, and improves in this way
The continuity that firepower is adjusted, will not allow firepower to become larger or become smaller suddenly；There are three first spool bore is set, the second spool bore is equipped with
Two, combustion gas can be achieved in this way from cut-off state, one section of burning minimum load state, two stage combustion minimum load state again to most
Big load condition continuously adjusts.
【Description of the drawings】
Fig. 1 is the stereogram of the utility model；
Fig. 2 is the explosive view of the utility model.
【Specific implementation mode】
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
As illustrated in fig. 1 and 2, a kind of gas heater regulating valve, including valve body 1, valve body 1 are equipped with 11 He of the first venthole
Second venthole 12, valve body 1 are interior axial along the spool 2 equipped with taper valve core 2, the first venthole 11 and the second venthole 12
Distribution, i.e. distribution up and down, the first venthole 11 is close to stub end, and close to small head end, spool 2 is equipped with the second venthole 12
The first spool bore 21 being connected to the first venthole 11 and the second spool bore 22 being connected to the second venthole 12, the first spool bore
21 are circumferentially at least two in spool 2, the first spool bore 21 on the same circumference, the first spool bore 21 close to stub end,
Second spool bore 22 is close to small head end, when one of them first spool bore 21 is connected to the first venthole 11, the second spool bore
22 are connected to the second venthole 12.At least two first spool bores, 21 phase is close to first spool bore 21 when spool 2 being made to rotate
It is gradually reduced with the communication port of the first venthole 11 and the first adjacent spool bore 21 and the communication port of the first venthole 11 are gradual
Increase, at least two first spool bores 21 are mutually close, and close distance makes two holes be connected to the first venthole 11 with certain
Continuity.The most preferred embodiment of regulating valve is there are three this first spool bore 21 is set, and one is in three the first spool bores 21
Macropore, two are aperture, and when spool 2 rotates, when going to big fire by small fire, aperture tapers into, and macropore becomes larger, two
It can be simultaneously in the first venthole 11 for aperture；There are two second spool bore 22 is set, two the second spool bores 22 1 are macropore,
One is aperture, and the macropore in the first spool bore 21 acts simultaneously with the macropore in the second spool bore 22 to be connected to.Macropore refers to, greatly
