Chinese patent CN201896969 discloses techniques below content: the many ball-valve single-knob linkage control valves of refrigerant recovering machine, including valve body, described valve body is provided with the compressor inlet channel and compressor air-discharging passage that are connected with compressor and the condensation inlet channel being connected with condenser and condensation exhaust passage, it is provided with threeway air inlet ball valve between described compressor inlet channel and condensation inlet channel, the valve rod of described threeway air inlet ball valve is provided with the intake valve linkage gear of synchronous axial system, it is provided with threeway venting ball valve between described compressor air-discharging passage and condensation inlet channel, the valve rod of described threeway venting ball valve is provided with the air bleeding valve linkage gear of synchronous axial system, described condensation exhaust passage is provided with tee-joint function ball valve, the valve rod of described tee-joint function ball valve is provided with the travelling gear of synchronous axial system, described travelling gear engages with intake valve linkage gear and air bleeding valve linkage gear and synchronous axial system simultaneously.
Although it is loaded down with trivial details that above-mentioned technology contents solves control valve adjustment process when refrigerant recovering machine uses, very easily cause because of maloperation that recycling machine cannot the technical problem of normal operation, but its valve volume is bigger than normal, path is complicated, can cause that the loss of cold-producing medium or residual quantity are bigger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of easy to process, application valve body and amasss little, path and design simple two steel ball linkage controlling valves.For this, this utility model by the following technical solutions:
A kind of two steel ball linkage controlling valves, including the control valve body being connected with compressor and condenser, valve body is offered air inlet and the exhaust passage of compressor and condenser respectively, two logical air inlet ball valve and threeway venting ball valves it are provided with in described valve body, the valve rod of two logical air inlet ball valves is provided with driven synchronous pulley, the valve rod of threeway venting ball valve is provided with active synchronization belt wheel, is arranged with Timing Belt outside driven synchronous pulley and active synchronization belt wheel so that driven synchronous pulley and active synchronization belt wheel synchronous axial system；The valve stem end of described threeway venting ball valve is provided with knob.The setting of Timing Belt decreases the ball valve quantity controlled in valve body, for the medium pipeline of copper pipe link, adds its working life and safety；By the setting of master and slave synchronous pulley, when three-way bar balloon Vavle switching is turned on and off pattern, two logical air inlet ball valves can be driven simultaneously to open and to reclaim or open from cleaning function.
Adopting on the basis of technique scheme, this utility model also can adopt technical scheme further below:
Described active synchronization belt wheel and driven synchronous pulley engage with Timing Belt.
Described two logical air inlet ball valves are located between compressor inlet channel and condenser inlet channel, and threeway venting ball valve is located between compressor air-discharging passage and condenser inlet channel.
The input of described two logical air inlet ball valves is connected with compressor inlet channel, or is connected with condenser inlet channel.
The input of described threeway venting ball valve is connected with compressor air-discharging passage, or is connected with condenser inlet channel.
When medium enters the entrance of compressor inlet channel from valve body inlet channel, select to enter condenser inlet channel through two logical air inlet ball valves, when entering the exhaust passage of condenser then through condenser, it may be achieved the process of refrigerant-recovery；When medium condenser inlet channel through threeway venting ball valve select be connected with compressor time, the cold-producing medium in condenser directly from compressor air-discharging passage to outlet passageway discharge, it is achieved internal system from clear process.
Adopt the technical solution of the utility model, the knob on swivel tee ball valve is only needed during work, can be driven and driven synchronous pulley and Timing Belt engaged transmission by active synchronization belt wheel, realize the synchronous working of ball valve, operate very easy, can avoid the recycling machine that operational error causes cannot normal operation.Owing to controlling to be provided only with two ball valves in valve body, reducing the volume controlling valve body, the design between each path connects also simple, decreases loss and the residual of cold-producing medium.Meanwhile, the passage controlling size and air flue that simple structure in valve body also can better control over decrement flows to, and can avoid liquid hit phenomenon that operation causes when reclaiming owing to air inflow is excessive, the phenomenon such as the too high deadlock caused of admission pressure when clear.
