Abstract
The utility model relates to a three-way valve set, and belongs to the technical field of oil gas recovery equipment through an adsorption method in a gas station. The three-way valve set can be widely used in the petroleum industry, the chemical industry, the natural gas industry, power stations, the metallurgy industry, the light industry, the manufacturing industry, the refrigeration industry and other industries. The three-way valve set comprises three three-way ball valves, a connecting rod box and a connecting rod, wherein the three three-way ball valves are fixed on the connecting rod box, and a valve rod of each three-way ball valve is connected on the connecting rod in the connecting rod box. Considering that the three three-way ball valves are switched at the same time, the three three-way ball valves are combined into the three-way valve set through the valve rods, the connecting rod, the connecting rod box and other structures, an actuator is used for controlling the three-way valve set, and therefore a whole adsorption system is enabled to be more compact in structure, lower in manufacturing cost and running cost and more flexible in operation.
Description
Technical field
The utility model belongs to gas station's adsorption method oil-gas recovery device technical field, relates in particular to a kind of three-way valve group, can be widely used in the industries such as oil, chemical industry, rock gas, power station, metallurgy, light industry, manufacturing, refrigeration.
Background technique
The adsorption tanks that two alternations are arranged in gas station's Vapor Recovery Equipment with Adsorption, satisfy its job requirement, need to install two electric/pneumatic valves on the air inlet pipeline, need to install two electric/pneumatic valves on the gas exhaust piping, two electric/pneumatic valves also need be installed on the desorb pipeline, consider that it is economical, the requirement such as sealability and flexible operation, we have designed a kind of patent No. is 200820034510.0 T-shaped tee ball valve, and we only need three T-shaped tee ball valves just can satisfy its need of work like this.
Above-mentioned three T-shaped tee ball valve work need be controlled respectively and take up room greatly, and complete sets of equipment is not compact.
The model utility content
For above-mentioned technical problem, the utility model provides the three-way valve group of a kind of compact structure, low cost of manufacture.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of three-way valve group comprises three tee ball valves, and described three-way valve group comprises connecting rod case and connecting rod, described three tee ball valves are fixed on the connecting rod case, and its valve rod is connected on the interior connecting rod of described connecting rod case.
Consider that these three tee ball valves all switch at the same time, we are by structures such as valve rod, connecting rod, connecting rod casees, three tee ball valves are combined into a three-way valve group, realize control to this three-way valve group with a final controlling element, thereby so that whole adsorption system structure is more compact, manufacture cost is less, operating cost is lower, the operation is more flexible.
Description of drawings
Fig. 1 is the utility model three-way valve group perspective view;
Fig. 2 is the utility model three-way valve group side structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As depicted in figs. 1 and 2, the utility model three-way valve group comprises three tee ball valves 1, and described three-way valve group comprises connecting rod case 2 and connecting rod 3, and described three tee ball valves 1 are fixed on the connecting rod case 2, and its valve rod 4 is connected on the interior connecting rod 3 of described connecting rod case.
The utility model three-way valve group has two working positions, nine paths, and three three-way valve are respectively exhaust three-way valve, desorb three-way valve, air inlet three-way valve from top to bottom.The three-way valve group connects respectively air inlet master gas phase pipeline, adsorption tanks suction port, air-inlet of vacuum pump, adsorption tanks relief opening and exhaust main gas phase pipeline.
When the air inlet three-way valve was communicated with gas phase pipeline and adsorption tanks A air inlet pipeline, desorb this moment three-way valve was communicated with adsorption tanks B air inlet pipeline and air-inlet of vacuum pump, and exhaust three-way valve then is communicated with adsorption tanks A gas exhaust piping and exhaust main gas phase pipeline; When adsorption tanks A adsorbs saturated need and switches to the B tank and adsorb, final controlling element work, the spool of sequence tape ovable valve stem, connecting rod and three tee ball valves, thereby the working position of switching three three-way valve.
Adopt after the three-way valve group final controlling element 5 to control because three three-way valve are merged into, this spline structure is more compact, the control simple and flexible, make the operating cost reduction, and can satisfy the operating mode needs, has good Economy and practicability.
Above embodiment's description is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
