Abstract
The utility model relates to a control device for a proportional valve in a gas water heater, which comprises a valve body, a valve spool, a push part and an electromagnetic coil. The push part is used for pushing the valve spool in displacement so as to change output flow of the proportional valve, and the electromagnetic coil is used for applying force to the push part. The control device is characterized in that a cavity is reserved between the push part and the valve body, and an output port of a fan of the gas water heater is communicated with the cavity through a pipe. When the control device is compared with the prior art, wind pressure generated by the fan of the gas water heater and thrust generated by the electromagnetic coil are utilized jointly to control openness of the proportional valve so as to achieve the purpose of controlling gas pressure of the constant-temperature gas water heater, the failure of constant temperature effect due to the fact that temperature of outlet water of the water heater changes along with reduction of gas pressure since heat loss of the electromagnetic coil is increased along with increase of current in the electromagnetic coil when the openness of the proportional valve is controlled by a computer panel individually can be reduced well, while the gas water heater is more energy-saving and environment-friendly.
Description
Technical field
The utility model relates to the control gear of Proportional valve in a kind of gas water-heater.
Background technique
General meeting usage ratio valve is regulated the gaseous-pressure of output in the existing gas water-heater, Proportional valve generally comprises valve body, spool, make spool in valve body, produce the driving member that displacement changes Proportional valve output flow size thereby be used to promote spool, and be used for applying the electromagnetic coil of active force to described driving member.The working principle of Proportional valve is: control the size of electric current in the electromagnetic coil separately by the computer plate, along with the increase of electric current in the electromagnetic coil, the displacement of driving member in spool increases gradually, and the gas flow of Proportional valve output is also just big more.But increase along with electric current in the electromagnetic coil, the loss of the heating value of electromagnetic coil also just increases, thereby so just be easy to cause gaseous-pressure reduce cause that the water-exit temperature of water heater changes thereupon, also just can not reach the situation of constant temperature effect, also not enough simultaneously energy-conserving and environment-protective.
The model utility content
Technical problem to be solved in the utility model at above-mentioned prior art a kind of energy-conserving and environment-protective are provided, to the control gear of Proportional valve in the accurate more gas water-heater of the water-exit temperature of water heater control.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the control gear of Proportional valve in this gas water-heater, described Proportional valve comprises valve body, spool, thereby being used to promote spool makes spool produce the driving member that displacement changes Proportional valve output flow size in valve body, and be used for applying the electromagnetic coil of active force to described driving member, it is characterized in that: have cavity between described driving member and the described valve body, the delivery outlet of the blower fan of described gas water-heater is communicated with described cavity by pipeline.
As improvement, described driving member comprises:
The push rod of fixedlying connected that can under described electromagnetic coil effect, be subjected to displacement with described spool;
The bearing disc of fixedlying connected with described push rod;
Be fixed on the described bearing disc and and described body cavity between form the air blast film of sealing.
Preferably, described push rod and described spool are integral piece.
Compared with prior art, advantage of the present utility model is: thus the aperture of the common control ratio valve of thrust that wind pressure that the blower fan of use gas water-heater own produces and electromagnetic coil produce reaches the purpose of the gaseous-pressure of control constant temp gas water heater, electric current when this control mode can well reduce by the aperture of the independent control ratio valve of computer plate, increase along with electric current in the electromagnetic coil, the loss of coil heating amount also just increases, thereby cause then gaseous-pressure reduce cause that the water-exit temperature of water heater changes thereupon, also just can not reach the situation of constant temperature effect, also more energy-conserving and environment-protective simultaneously.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Control gear as Proportional valve in Fig. 1, Fig. 2 and the gas water-heater shown in Figure 3, wherein said Proportional valve comprises valve body 1, spool 2, thereby being used to promote spool makes spool produce the driving member that displacement changes Proportional valve output flow size in valve body, and be used for applying the electromagnetic coil 4 of active force to described driving member, the automatically controlled plate that links to each other with electromagnetic coil, wherein said driving member comprises the push rod 5 of fixedlying connected with described spool that can be subjected to displacement under described electromagnetic coil effect, in the present embodiment, push rod 5 is the integral piece structure with spool 2; The bearing disc 6 of fixedlying connected with described push rod 5; Be fixed on the described bearing disc 6 and and described body cavity between form the air blast film 7 of sealing, the air blast film is an epithelium, have cavity 10 between above-mentioned driving member integral body and the described valve body 1, and the delivery outlet of the blower fan 8 of gas water-heater is communicated with described cavity 10 by pipeline 9.
When the elastic force that produces when the spring between spool and the valve body 11 added blower and pipeline and imposes on the wind pressure sum of air blast film and bearing disc greater than the active force that is imposed on push rod 5 by electromagnetic coil 4, Proportional valve was in closed condition, referring to shown in Figure 4.
When the elastic force that produces when the spring between spool and the valve body added blower and pipeline and imposes on the wind pressure sum of air blast film and bearing disc less than the active force that is imposed on push rod 5 by electromagnetic coil 4, Proportional valve was in normal opening state, referring to shown in Figure 5.
The elastic force that produces when the spring between spool and the valve body is when the active force that is imposed on push rod 5 by electromagnetic coil 4 adds blower and pipeline and imposes on the wind pressure sum of air blast film and bearing disc, the Proportional valve spool also pushes up uppermost position, this moment, Proportional valve was in maximum open mode, referring to shown in Figure 6.
