Abstract
The utility model relates to a three-position regulatable three-way change-over valve which is composed of a valve body, a valve switching regulating system, a sealing device, a pneumatic actuator, a travel switch, etc., wherein the upper surface of the valve body is provided with two chambers which are symmetrical and the lower surface is provided with one chamber. Two valve ports which are symmetrical are arranged on the upper surface of the chamber of the lower surface, and three chambers are respectively connected with an outer pipeline. A middle hole of a lever of the valve switching regulating system is arranged at the inner end of a drive shaft, and both ends are respectively contacted with a tray when the valve is opened. The upper surface of the tray is in contact with a return spring, the tray is arranged at the upper end of a valve rod and the lower end of the valve rod is in contact with a valve flap. A sealing is a seal gasket with temperature resistance and corrosion resistance which is arranged on the bottom surface of the valve clack. The seal ring and the spring are arranged in a casing tube of the valve rod. The pneumatic actuator is composed of an electromagnetic valve, a cylinder and a shifting fork, wherein the upper end of the shifting fork is clamped on a pin of a cylinder shaft and the lower end is arranged on the outer end of the drive shaft. The close of the valve is observed by the travel switch.
Description
Technical field
The utility model is fluid line valves such as liquid, high-temperature gas, combustion gas, especially for three adjustable three-way diverter valves of special use of HTAC.
Background technique
The triple valve that existing market is sold is easy to generate three chamber intercommunications (short circuit) when commutation, troublesome poeration, and fluid loss is bigger, and valve opening is observable not.
Summary of the invention
A kind of three adjustable three-way diverter valves that the purpose of this utility model designs in order to overcome existing deficiency in the above-mentioned prior art just, this valve mechanism is reasonable, and is easy and simple to handle, and the intercommunication short circuit phenomenon can not take place when commutation.
The purpose of this utility model realizes by following scheme: these three adjustable three-way diverter valves are made up of valve body, valve opening and closing regulating system, seal arrangement, pneumatic actuator, position limit switch etc., two chambers and a following chamber that symmetry is arranged above the valve body, the symmetry two valve ports be located at lower chambers above, three chambers are connected with external pipe respectively, and two valve ports contact with flap respectively when closing valve; The valve opening and closing regulating system, the lever mesopore is contained in the inner of live axle, the lever two ends contact with pallet respectively when driving valve, contact with Returnning spring above the pallet, pallet is contained in the valve rod upper end, valve rod lower end and flap flexibly connect, and spacing screw rod is equipped with on Returnning spring top, end in contact on the valve rod when spacing screw rod lower end and valve are opened; Seal arrangement, flap are equipped with heatproof, anti-corrosion sealing gasket, in the valve rod sleeve pipe of two symmetries of cavity top cover seal ring and spring are housed below the valve body; Pneumatic actuator is made up of solenoid valve, cylinder, shift fork, and the shift fork upper end is stuck on the pin of cylinder axis, and the lower end is contained on the outer end of live axle; The inner pallet during with valve closing of position limit switch contacts, and the outer end is connected with telltale.
These three adjustable three-way diverter valves compared with prior art have following advantage:
1, when commutation can the intercommunication short circuit, and be easy and simple to handle;
2, save fluent material;
3, valve opening degree adjustable size, but direct observation are closed sternly and intuitively can not known.
