Description
Technical field
The present invention relates to a kind of control device that is used for dental therapeutic tool, be specifically related to a kind of pneumatic combination valve that is used for interlock control hand-held apparatus on the dental therapeutic apparatus.
Background technology
In dental treatment, most crucial on the dental therapeutic apparatus, the most frequently used therapeutic appliance is exactly a hand-held apparatus, and general standard is formulated as: one three ways syringe, two high speed air turbine mobile phone, low speed gas motor mobile phone, the machine that cleans one's teeth.The driving gas of these hand-held apparatus, the output of blowing bits gas, press water, pressure gas and electricity all need by gas signal and signal of telecommunication control, thereby reach the purpose of logic output.
On current dental therapeutic apparatus, usually adopt many pneumatic apportion elements or simple combination valve to add pneumatic apportion element both at home and abroad, outside by pipeline connects, realize driving gas, blow the input control hand-held apparatus of considering gas, power and water to be worth doing, this form had both been wasted space limited in the apparatus dish and had been connected the trachea cabling attractive in appearance, should form the loaded down with trivial details hidden danger that causes air water to drip, leak, run of pipeline connection again.Therefore, highly integrated combination valve is applied on the dental therapeutic apparatus, has high practicality and economy.
Summary of the invention
Purpose of the present invention just is to change the deficiency of control device of the dental therapeutic tool of present use, and a kind of pneumatic combination valve that is used for interlock control hand-held apparatus on the dental therapeutic apparatus is provided.
Pneumatic combination valve provided by the invention be mainly used in control one three ways syringe, two high speed air turbine mobile phone, low speed gas motor mobile phone, a handle machine that cleans one's teeth.Wherein be divided into three kinds of control types again, the first kind one tunnel control one is three ways syringe, second class three tunnel control respectively two high speed air turbine mobile phone and low speed gas motor mobile phone, the 3rd class one tunnel control one handle machine that cleans one's teeth.Carry out the output of some auxiliary gas signals simultaneously.Combination valve is one road pressure gas (0.5Mpa) and one road press water (0.2-0.4Mpa) to be arranged as entering combination valve total road input, export one road pressure gas and press water supply three ways syringe respectively by the passage of valve inner, produce gas, water, three kinds of functions of mist by the air water button on the operation three ways syringe.Realize that one group of control one of the first kind is the three ways syringe function.Second class independent three tunnel is by the input of gas signal separately, form through inner all kinds of pneumatic operated valves and to supply with the required driving gas of mobile phone separately, blow bits gas and press water passage, at this moment, action peripheral components foot control, make mobile phone obtain required driving gas, blow bits gas and press water, combination valve is exported force value signal gas and machine chair interlocking electric switch signal gas at random simultaneously.The 3rd class is leaded up to the input of gas signal and is formed through inner all kinds of pneumatic operated valves and supply with the required press water of the machine that cleans one's teeth and the machine electric switch signal gas passage that cleans one's teeth, move the peripheral components foot control this moment, make the machine that cleans one's teeth obtain the required press water and the machine electric switch signal gas that cleans one's teeth, the triggering machine electric switch that cleans one's teeth satisfies the machine work duty of needs press water and power supply simultaneously that cleans one's teeth.The machine of combination valve output simultaneously chair interlocking signal gas.When the machine of cleaning one's teeth was in off working state, the unloader inner independent by the machine that cleans one's teeth discharged the machine electric switch signal gas that cleans one's teeth, and guarantees to close the dynamo-electric source that cleans one's teeth.
The present invention is by regulating the adjustment screw of combination valve, and the inner corresponding choke valve of control combination valve is controlled each group gas, water and the flow that blows bits gas.Wherein, second class three tunnel three mobile phone and the 3rd class one tunnel one input different of the machine gas signal that cleans one's teeth, be divided into two kinds of forms again, thereby form two types combination valve: automatically controlled combination valve and gas control combination valve.
Ecp combination valve provided by the invention is: miniature electromagnetic valve directly is housed in combination valve, drives miniature electromagnetic valve through external electric signal, produce input gas signal.Pneumatically controlled combination valve provided by the invention is: the gas signal input interface is arranged in combination valve, through the input of peripheral components signal gas, produce input gas signal.More than two kinds of combination valves multiple functional, compact conformation, volume is little, suitable maintaining.
Below, the present invention is further illustrated with embodiment in conjunction with the accompanying drawings.
