Abstract
The utility model discloses an adjustable thermostat for gas water-heater which contains a water temperature transducing head 1, an expanded bag 2 and an adjustable air valve 4. The utility model is characterized in that the transducing head is provided with two disconnected cavities, an external cavity 7 is provided with an interface 10 and a hot water outlet 6 which is connected with the hot water pipe of the water heater, an inner cavity 8 is provided with a connection pipe 9 connected with the expanded bag 2, and the expanded bag penetrates one end of a lever or directly contacts with a regulator 3 arranged on the valve core 11 of the adjustable air valve. Because of the structure, the positive effect of the utility model is the utility model has simple structure, practicability, the thermostat can be added on the common water heater, or directly arranged when the gas water-heater is made. The function of the gas water-heater is increased, the attemperator of the existing common water heater can be omitted, and the manufacturing cost is saved.
Description
Technical field
The utility model relates to thermostat, particularly a kind of adjustable gas heater thermostat.
Technical background
Commonly used gas heater all can not constant temperature in the prior art, if will adjust water temperature, then can only be in the size of dried up tap gas heater adjusted air valve far away, thus control firepower size reach the purpose of regulating water temperature.The method of this adjusting water temperature is very inconvenient, particularly more inconvenient when having a bath, because gas heater can not be installed in the bathroom, if meet the hydraulic pressure shakiness, or artificially control discharge when size, and flow reduces, and water temperature raises, flow increases, and water temperature is reduced in and meets when having a bath is exactly the thing of at all having no idea.Yet in the prior art, comparatively advanced computer control adjustable thermostatic gas heater also arranged, though the thermostat of this water heater has solved the problem that common water heater can not constant temperature, because of complex structure with high content of technology, cost is very high, compare the valency that common water heater will exceed several times, general family buys, and certain difficulty is all arranged, if damage is arranged, then general maintenance mans can't repair, and add that it must use power supply, all can't use if meet situation such as power failure.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and regulates easy to usely, and cost is very low, the gas heater adjustable thermostat of reliable and stable and durable a kind of frame for movement formula.
The technical solution adopted in the utility model is such, and promptly a kind of gas heater adjustable thermostat comprises water temperature sensing head 1, and bag 2 and adjustable air throttle expand; It has two disconnected cavitys to it is characterized in that special sensing head, outer chamber has interface and the hot water outlet that links to each other with the water heater hot-water pipe, inner chamber body has tube connector and is connected with the bag that expands, and an end or the adjuster direct and on the spool that is installed in adjustable air throttle that wraps by lever that expand contacts.
The operation principle of said structure is such: when the hot water that water heater flows out passes through outer chamber fully, the gas that inner chamber body has or the induction water temperature of efficient liquid are changed, after thereby gas that inner chamber body exists or liquid temperature sensor change, produce and expand, the process of shrinking, thereby by the tube connector that links to each other with interior space, make the effectively work of bag of expanding, the expansion of the bag that expands also can directly promote the adjuster cup head of adjustable air throttle by lever, thereby promote spool and regulate the gas flow size, water temperature raises, and throughput reduces, and water temperature reduces, throughput increases, and reaches the purpose of automatic constant-temperature.
Because behind the effluent temperature constancy, the size variation of discharge, can not influence the variation of water temperature, thereby when using hot and cold water to mix water valve, the adjusting of water temperature can directly in the mixed discharge of mixing water valve (tap) adjusted hot and cold water, reach own optimal temperature according to artificial hobby, like this, not only easy to use, and economize on the effect of gas in addition, simultaneously, also played water-saving effect, because when using gas heater, the water temperature of water temperature sensing head induction all is lower than set water temperature each, so the time adjustable air throttle set back, open amount is bigger, before water temperature did not reach design temperature, firepower was bigger, like this, can in the time faster, reach set water temperature, avoided cold water in the water pipe not reaching when using water temperature the possibility that bleeds off in vain.
Description of drawings
Said structure of the present utility model can further specify by the embodiment that accompanying drawing is constructed.
Accompanying drawing 1 is the structural representation of utility model;
Accompanying drawing 2 is the structure cutaway view of water temperature sensing head;
Accompanying drawing 3 is the structure cutaway view of adjustable air throttle.
Referring to accompanying drawing, 1-sensing head, 2 among the figure-expansion bag, adjuster, the 4-adjustable air throttle of 3-regulator valve, 5-water heater, 6-hot water outlet, 7-outer chamber, 8-inner chamber body, 9-tube connector, 10-water heater connector; 11-spool, 12-inlet channel, 13-back-moving spring.
The specific embodiment
Referring to accompanying drawing 1: adjustable thermostat in the dotted line among the figure, comprise water temperature sensing head 1, bag 2 and adjustable air throttle 4 expand; It is characterized in that sensing head has two disconnected cavitys, outer chamber 7 has joint 10 and the hot water outlet 6 that links to each other with the water heater hot-water pipe, inner chamber body has tube connector and is connected with the bag that expands, and an end or the adjuster 3 direct and on the spool that is installed in adjustable air throttle that wraps by lever that expand contacts.
T type spool 11 is installed in the inlet channel of described adjustable air throttle, and the T type end of spool is by the centering position of the maintenance spool of spring, and the other end of spool is threaded with adjuster 3.
Adjuster 3 is to be used for that it regulates the cup head and the bag that expands, or by the gap between the lever transmission, or pressure, makes hot water temperature that water heater flows out reach the set water temperature of adjuster high scale.Simultaneously, adjustable air throttle also can use plug-type air valve of the prior art or rotary handle type air valve, and by lever, the transfer mode of gear etc. reaches the purpose of regulating the throughput size.
The good effect that the utility model produces owing to said structure is obviously: simple in structure, practicality both can be installed this thermostat additional on common water heater, also can directly install when making gas heater.Like this, not only increase the function of gas heater, but also can save the register of existing common water heater, thereby saved manufacturing cost.
