Abstract
The invention relates to a control device of a proportional valve in a gas water heater. The proportional valve comprises a valve body, a valve spool, a push component and an electromagnetic coil, wherein the push component is used for pushing the valve spool so as to enable the valve spool to generate displacement in the valve body, thereby changing the magnitude of the outputting flow rate of the proportional valve; and the electromagnetic coil is used for applying acting force to the push component. The control device of the proportional valve in the gas water heater is characterized in that a hollow cavity exists between the push component and the valve body, and the output port of a fan of the gas water heater is communicated with the hollow cavity by a pipeline. Compared with the prior art, the opening degree of the proportional valve is controlled together by using wind pressure generated by the self fan of the gas water heater and thrust force generated by the electromagnetic coil in the invention, thereby achieving the aim of controlling the gas pressure of a constant-temperature gas water heater; the conditions that the loss of the heat productivity of the coil also is increased along with the increase of current in the electromagnetic coil when the opening degree of the proportional valve is independently controlled by a computer panel, then the decrease of the gas pressure is caused so as to cause the change of the water outlet temperature of the water heater along with the decrease of the gas pressure and the constant-temperature effect also can not be achieved can be reduced very well; and meanwhile, more energy also is saved, and the environment is protected.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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, the invention has the advantages that: 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 present invention 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.
