Abstract
The invention relates to a leather bag type energy accumulator. The leather bag type energy accumulator comprises a tank body, a leather bag, an air inlet and an oil inlet; the leather bag which is used for performing nitrogen filling is arranged in the tank body; the leather bag is in a plate shape; the leather bag is connected with the air inlet; the air inlet is provided with a bolt which is used for performing sealing; the outer side of the air inlet is provided with an upper end cover; a lift valve is arranged in the oil inlet; the outer side of the oil inlet is provided with a lower end cover which is used for performing sealing. The leather bag type energy accumulator has the advantages of being simple in structure, good in sealing performance, long in service life and the like.
Description
Technical field
The present invention relates to accumulator technical field, particularly bag type accumulator.
Background technique
Accumulator can be used to the hydraulic shock power produced in the pressure pulsation of absorption liquid press pump or absorption system.Bag type accumulator is the one in accumulator, and bag type accumulator is used for separation gas and liquid, and leather bag volume change is large, and absorption pressure pulsation effect is good, but the defect such as existing bag type accumulator also exists sealing difference, and sealing effect is bad.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, good airproof performance, the bag type accumulator that physical life is long.
Realize technological scheme of the present invention as follows:
Bag type accumulator, comprise tank body, leather bag, suction port and filler opening, be provided with the leather bag for inflated with nitrogen in described tank body, shape that leather bag is set to " plate ", leather bag is connected with suction port, and suction port is provided with the bolt for sealing, and is provided with and is also provided with upper end cap outside suction port, being provided with poppet valve in filler opening, outside filler opening, being provided with the lower end cap for sealing.
Described poppet valve comprises the valve block be fixedly installed on suction port, valve block is provided with fixing rod, on fixing rod, top is provided with for closed filler opening pallet, be connected by the spring of winding on fixing rod between pallet with valve block, pallet is provided with the through hole adapted with fixing rod, and advantage is that pallet can be moved up and down by spring, can be used for when pallet separates with filler opening refuel and fuel-displaced, be closed state when pallet and filler opening close contact, prevent oil leakage phenomenon from occurring.
Be provided with seal ring between described poppet valve and tank body, ensure good sealing.
Described upper end cap is all set to be threaded with filler opening with suction port, lower end cap, and advantage can form secondary seal to suction port and filler opening, is connected firmly.
Have employed above-mentioned scheme, shape that leather bag is set to " plate " can reduce the volume of accumulator on the one hand, but capacity can keep inconvenience, its weight can be alleviated accordingly on the other hand, bolt plays the effect of sealing after being used for that air bag is poured nitrogen, poppet valve in filler opening can be that fluid enters accumulator by filler opening, when also can prevent fluid from all discharging, air bag expands outside container, upper end should be form secondary seal with arranging of lower end cap on the one hand, on the other hand operator guards is formed to suction port and filler opening, prevent in atmosphere exposed for a long time and be corroded, damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, bag type accumulator, comprises tank body 1, leather bag 6, be arranged on the suction port 2 of tank body 1 upper end and the filler opening 3 of tank body 1 lower end, be provided with the leather bag 6 for inflated with nitrogen in described tank body 1, leather bag 6 is set to " plate " shape, and leather bag 6 is connected with suction port 2, suction port 2 is provided with the bolt 4 for sealing, being provided with outside suction port 2 and being also provided with upper end cap 5, in filler opening 3, be provided with poppet valve, outside filler opening 3, being provided with the lower end cap 11 for sealing.
Described poppet valve comprises the valve block 7 be fixedly installed on suction port, valve block 7 is provided with fixing rod 10, on fixing rod 10, top is provided with for closed filler opening pallet 8, be connected by the spring 9 of winding on fixing rod 10 between pallet 8 with valve block 7, pallet 8 is provided with the through hole adapted with fixing rod, advantage is that pallet can be moved up and down by spring, can be used for when pallet separates with filler opening refuel and fuel-displaced, be closed state when pallet and filler opening close contact, prevent oil leakage phenomenon from occurring.
Be provided with seal ring 12 between described poppet valve and tank body 1, ensure good sealing.
Described upper end cap 5 is all set to be threaded with filler opening 3 with suction port 2, lower end cap 11, and advantage can form secondary seal to suction port and filler opening, is connected firmly.
