Background technique

Pneumatic Transmission and control technique are called for short pneumatics, refer to pressurized air to be that working medium carries out energy and signal transmission, realize a special kind of skill of production process mechanization, automation, and it is an important component part of Fluid Transmission and Control subject.Because pneumatics has many outstanding advantages with respect to mechanical transmission, fax for the moving and hydraulic transmission, thereby development in recent years is very rapid, pneumatics combines numerous advantages of hydraulic pressure, machinery, Electrical and Electronic technology now, and it is additional mutually with them, become an important means that realizes process automation, be widely used in each departments such as machinery, metallurgy, weaving, food, chemical industry, communications and transportation, Aero-Space, national defense construction.

Typical pneumatic system comprises air machinery, pneumatic apparatus (as cylinder), pneumatic control components (as solenoid valve, Flow valve etc.), pneumatic auxiliary (gas source purification, element connection, noise elimination etc.), sensor and conversion element etc. now.Typical case's pneumatic structure is: manually operated valve is the interface of source of the gas and equipment pneumatic system, only closes when equipment is installed or keep in repair and dies, and often opens at ordinary times.Usual work rest outage period, whole pneumatic system still has been full of the pressurized air of high pressure, even the pneumatic system Security is higher, but the potential safety hazard of cylinder misoperation is arranged.Having a kind of in the prior art is to increase by two throughway valves, and the outage back cuts off gas circuit, still, still has pressurized air in the pneumatic circuit, has potential safety hazard.

The model utility content

Cut off gas circuit in order to overcome pneumatic circuit outage of the prior art back, but, still have pressurized air in the pneumatic circuit, have the deficiency of potential safety hazard, the purpose of this utility model is to provide a kind of air-balance control system that can improve pneumatic system Security and reliability.

To achieve these goals, to solve the technological scheme take as follows for the utility model:

Air-balance device control system comprises: total source of the gas, two accurate voltage regulating valves (two can be identical, also can one big add one little), one or valve, two-bit triplet manually operated valve, one-way valve, executive component, total air outlet; The input end UNICOM of the output terminal of described or valve and total air outlet, with the output terminal UNICOM of total air outlet be executive component; It is characterized in that: two interfaces of an accurate voltage regulating valve in described two accurate voltage regulating valves respectively with or the input end of valve and total source of the gas UNICOM, form idle loop; Two interfaces of another accurate voltage regulating valve respectively with an interface UNICOM of total source of the gas and one-way valve, an interface UNICOM of another interface of one-way valve and two-bit triplet manually operated valve, another interface of two-bit triplet manually operated valve with or the input end UNICOM of valve, be formed with and carry a main air circuit; The 3rd interface of two-bit triplet manually operated valve is pressure relief opening.

Below technique scheme is further elaborated:

Come gas can divide two pneumatic circuits from total source of the gas: a pneumatic circuit is the idle loop of controlling no-load running; Another pneumatic circuit is the main air circuit of carrying that has of controlling on load operation.Can by or valve carry out the conversion of two pneumatic circuits; Require to have when being zero load and carry main air circuit cut-out, idle loop is logical, and what at this moment come out from total air outlet is little air pressure, and air-balance device control system is in unloaded state of suspension, can be used to the weight of the frock clamping on the balance cylinder; When being has to require to have when carrying to carry main air circuit ventilation, what at this moment come out from total gas port is barometric pressure, and air-balance device control system is in the state of suspension of carrying, and can be used to balance frock clamping and load transported weight.

Have to carry on the main air circuit one-way valve is installed, be used for safety effect.When total gas circuit was died suddenly, main gas circuit did not have return-air, thereby general export air pressure is kept operation machinery was failure to actuate, and left the certain reaction time to the operator.

Further, in order to make whole atmospheric control safer, also can install a gas holder additional in the front of total source of the gas simultaneously.

Further, the pressure relief opening of described two-position three-way valve also with baffler UNICOM.

The utility model adopts happy one-way valve to carry out safety protection, makes pneumatic circuit and whole air-balance control system avoid potential safety hazard, has improved device security and reliability; And whole air-balance control system is simple in structure, adopts the normal component assembling to get final product, and no longer needs to carry out machining, can effectively reduce cost, easy-to-operat.
