Abstract
The utility model relates to a novel public valve station pressure oil pipeline of a pressure swing adsorption device. The public valve station pressure oil pipeline comprises a public valve station, a first oil charge valve, a second oil charge valve, a first oil return valve, a second oil return valve, a pressure oil pipe, an oil return pipe, an auxiliary oil tank and a master oil tank, wherein the pressure oil pipe is connected with the public valve station through the first oil charge valve and the second oil charge valve, one ends of the first oil return valve and the second oil return valve are respectively connected with the public valve station, the other ends of the first oil return valve and the second oil return valve are connected with one end of the oil return pipe, the other end of the oil return pipe is connected with one end of the auxiliary oil tank, and the other end of the auxiliary oil tank is connected with the master oil tank. The public valve station pressure oil pipeline adopts two program control valves to control in two ways; and when one valve is out of order, the on-line maintenance of the program control valve can be realized on the premise of not affecting the normal operation of the public valve station, the stop of the system is not required and the normal operation of the public valve station is not affected.
Description
Technical field:
The utility model relates to public valve station pressure oil pipeline, is specifically related to a kind of public valve station pressure oil pipeline of novel pressure-swing absorption apparatus.
Background technology:
The public valve station pressure oil pipeline of tradition pressure-swing absorption apparatus adopts flowing of single valve controlled pressure oil, in case break down can not on-line maintenance for sequencing valve, system shutdown just can be advanced by the time, influences the safe and stable operation at public valve station.
The utility model content:
The purpose of the utility model provides a kind of public valve station pressure oil pipeline of novel pressure-swing absorption apparatus; It adopts two sequencing valves to divide two-way to control; When breaking down, one of them valve do not influencing under the normal prerequisite of moving in public valve station; Can realize the on-bne repair of sequencing valve, need not wait until system shutdown, also not influence the normal operation at public valve station.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises public valve station 1, first oil-feed and cuts down 2, second oil-feed and cut down 3, first oil return valve 4, second oil return valve 5, pressure oil pipe 6, oil return pipe 7, auxiliary fuel tank 8, total fuel tank 9; First oil-feed of passing through of pressure oil pipe 6 is cut down 2 and is cut down 3 with second oil-feed and be connected with public valve station 1; One end of first oil return valve 4 and second oil return valve 5 is connected with public valve station 1 respectively; The other end is connected with an end of oil return pipe 7; The other end of oil return pipe 7 is connected with an end of auxiliary fuel tank 8, and the other end of auxiliary fuel tank 8 is connected with total fuel tank 9.
The utility model adopts two sequencing valves to divide two-way to control; When breaking down, one of them valve do not influencing under the normal prerequisite of moving in public valve station; Can realize the on-bne repair of sequencing valve, need not wait until system shutdown, also not influence the normal operation at public valve station.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it comprises public valve station 1, first oil-feed and cuts down 2, second oil-feed and cut down 3, first oil return valve 4, second oil return valve 5, pressure oil pipe 6, oil return pipe 7, auxiliary fuel tank 8, total fuel tank 9; First oil-feed of passing through of pressure oil pipe 6 is cut down 2 and is cut down 3 with second oil-feed and be connected with public valve station 1; One end of first oil return valve 4 and second oil return valve 5 is connected with public valve station 1 respectively; The other end is connected with an end of oil return pipe 7; The other end of oil return pipe 7 is connected with an end of auxiliary fuel tank 8, and the other end of auxiliary fuel tank 8 is connected with total fuel tank 9.
The oil that this specific embodiment is sent here by pressure oil pipe 6 cuts down 2, second oil-feed through first oil-feed and cuts down 3; Two sequencing valves get into public valve station 1 and use; The oil of returning gets into auxiliary fuel tanks 8 through oil return pipe 7 again through first oil return valve 4,5 two sequencing valves of second oil return valve, finally sends into total fuel tank 9.
This specific embodiment adopts two sequencing valves to divide two-way to control; When breaking down, one of them valve do not influencing under the normal prerequisite of moving in public valve station; Can realize the on-bne repair of sequencing valve, need not wait until system shutdown, also not influence the normal operation at public valve station.
