Description
Technical field
The present invention relates to pressurized container, relate in particular to fiber reinforced plastic pressure container.
Background technique
Reverse osmosis unit is used fiber reinforced plastic pressure container, is widely used in electric power, electronics, metallurgy, chemical industry, medicine, instrument, and industrial sewage is handled, fields such as desalination of sea water.Said fiber reinforced plastic pressure container when work the pressure more suffered than general water treatment vessels big, so the inlet/outlet positional structure intensity of its water of guarantee and the sealing of joint, the convenience of ne-leakage and installing/dismounting, in service, particularly important in whole system.At present, the main structure and the installation form of reverse osmosis fiber reinforced plastic pressure container lateral opening, as shown in Figure 1; Side mouth spare 1 is cylindric, the inner flange that forms, and the Kong Youyi that connects of container (putamina) 3 connects hole and counterbore formation; The counterbore shaft shoulder butt that the flange shaft shoulder of side mouth spare 1 and container connect the hole; The outside attaching nut of side mouth spare 1, thus side mouth spare is fixed on connecing in the hole of container 3, and the gap is through Sealing 2 sealings between side mouth spare and flange and the counterbore.Sealing part gap and seal ring thickness are owing to the difficult control of foozle, so can cause operational failure or assemble difficult.More disadvantageously be; As shown in Figure 2, the hole wall that connects to container in the container has outward pressure P, forms an angle of 90 degrees because container connects the counterbore in hole; An angle of 90 degrees is the stress concentrated position; As shown in Figure 3, an angle of 90 degrees causes the hole wall that connects of container to produce inefficacy crack 10 easily, and cylindrical bore is fatal to the weakening of glass fibre reinforced plastics structure of container intensity.
Summary of the invention
The object of the present invention is to provide a kind of fiber reinforced plastic pressure container, its joint is modified with the composite structure that connects the hole, thus the voltage endurance capability of reinforcing glass steel pressurized container.
Fiber reinforced plastic pressure container of the present invention has connecing the hole and being fixedly mounted on the joint that connects in the hole on the putamina side, is characterized in; Connecing the hole inner is internal diameter flaring portion, and internal diameter flaring portion increases towards the direction internal diameter in the putamina gradually, and joint the inner is an external diameter flaring portion; External diameter flaring portion increases towards the direction external diameter in the putamina gradually; The external diameter flaring portion of joint is accepted by the internal diameter flaring portion that connects the hole, and this internal diameter flaring portion contacts with this external diameter flaring portion face face, is sealed by Sealing between contact gap.
Described fiber reinforced plastic pressure container, its further characteristics are that this internal diameter flaring portion or external diameter flaring portion are conical surface, parabolic or arc surface.
Described fiber reinforced plastic pressure container, its further characteristics are to connect the hole for conical.
Described fiber reinforced plastic pressure container, its further characteristics be, connects Kong Youyi section cylindrical bore wall and this internal diameter flaring portion formation of joining, and the minimum diameter of this internal diameter flaring portion equals the internal diameter of cylindrical bore wall.
Described fiber reinforced plastic pressure container, its further characteristics are that internal diameter flaring portion is conical.
Described fiber reinforced plastic pressure container, its further characteristics are that conical bus is a smoothed curve.
The invention has the beneficial effects as follows:
Internal diameter flaring portion increases towards the direction internal diameter in the putamina gradually; External diameter flaring portion increases towards the direction external diameter in the putamina gradually, and the external diameter flaring portion of joint is accepted by the internal diameter flaring portion that connects the hole, and this internal diameter flaring portion contacts with this external diameter flaring portion face face; The pressure that promptly is applied on the joint will be delivered to external diameter flaring portion and the internal diameter flaring portion that the face face cooperates; Because the diameter of each flaring portion gradually changes, therefore can not form the wedge angle that causes stress to be concentrated, so the voltage endurance capability of fiber reinforced plastic pressure container.Said flaring is meant that the sudden change of step evolution can not appear in diameter.

Embodiment
As shown in Figure 4, be formed with on the sidewall of fiber reinforced plastic pressure container putamina 5 and connect hole 4, connect hole 4 and be roughly the taper shape (internal diameter flaring portion) of decaptitating, clipped a part of putamina 5 among Fig. 1, so that observe the shape that connects hole 4.The big end 20 that connects hole 4 is positioned at putamina 1 inboard, and small end 21 is positioned at putamina 1 outside.Connect the edge chamfer of the small end 21 in hole 4, form a bit of columned sidewall 210.The small end 21 that connects hole 4 along the circumferential direction also is evenly equipped with a plurality of keyways 211.
From Fig. 5 and Fig. 6, can more be clear that the shape that connects hole 4.Fig. 5 is along being parallel to the sectional drawing that face that putamina 5 axial passing through connect the centre in hole 4 is cut open.Fig. 6 is along being parallel to the sectional drawing that face that putamina 5 passing through radially connect the centre in hole 4 is cut open.
Like Fig. 7 and shown in Figure 10; Joint 6 is fixed on and connects in the hole 4; Joint 6 is a tubular, and the inner of joint 6 part outer side surface at least is the conical surface (external diameter flaring portion) of decaptitating, and the tapering of the conical surface of joint 6 is roughly the same with the tapering that connects hole 4; The conical surface of joint 6 contacts with the wall surface of the hole face that connects hole 4, and is provided with seal ring 8 between the contact gap.
The said conical surface restriction that the degrees of freedom that joint 6 moves outside putamina 5 is engaged; The outer end of joint 6 is connected with fastening piece 7; Fastening piece 7 for example is threaded with joint 6 outer ends, degrees of freedom fastener 7 restrictions that joint 6 moves in putamina 5, so fastening piece 7 is fixed on and connects in the hole 4.The outer periphery of joint 6 also is evenly equipped with keyway, rotates in connecing hole 4 in order to prevent joint 6, strong 212 be placed on joint 6 keyway, connect in the keyway in hole 4, promptly key jointing 6 with connect hole 4.
Shown in figure 12, applied pressure P can be decomposed into axial thrust load P at joint 6 and the contact position that connects between the hole 4 in the putamina 5 on joint 6
qWith radial component P
t, be compared to structure shown in Figure 2, owing to stress surface increases, and putamina 5 there is the power P of destruction
tReduced not for a short time, stressing conditions is greatly improved.
As shown in Figure 8, the hole 4 that connects of putamina 5 is made up of a cylindrical hole and cone shape hole and is formed.As shown in Figure 9, putamina 5 connect hole 4 for being similar to the hole of taper, only the bus of taper becomes camber line by straight line.
Internal diameter flaring portion and the joint 6 external diameter flaring portions that connect hole 4 are other shapes also, for example be flaring type curved surfaces such as conical surface, parabolic perhaps arc surface, and for example bus is the cylinder shape of smoothed curve again.
To be used to accept the wedge angle that does not concave on the hole wall of joint 6 just passable as long as connect the hole wall in hole 4, and this wedge angle for example is right angle shown in Figure 3, and perhaps angle is less than the angle of 90 degree.
The internal diameter flaring portion that connects hole 4 is similar or identical in fact shapes with joint 6 external diameter flaring portions, to realize that the face face is fitted or the effect of contact.
The hole that connects among aforementioned each embodiment for example is to process with broaching tool.
