Abstract
The invention relates to a sleeve valve, which comprises an outer barrel (1) and an adjustment barrel (2) which can relatively slide up and down in the outer barrel (1), wherein a sealing device consisting of a flange (3), an upper sealing ring (4) of which the inner edge is upwards bent and a pressing plate (5) is arranged at the end of the outer barrel (1); and a lower sealing ring (8) of which the inner edge is downwards bent is arranged between the upper sealing ring (4) and the flange (3). An oil storage tank can store more lubrication oil, and the sealing effect is relatively good.
Description
Technical field
The present invention relates to a kind of valve, especially relate to a kind of telescoping valve.
Background technique
Telescoping valve claims to promote valve again, generally is used for the sludge from sedimentation tank well and carries out spoil disposal outside the pond, because its structure is inside and outside extension sleeve; So also can be used for regulating water level in distribution well or the wet well; For example single-tube suction dredge mud extraction, air supporting water outlet etc. are generally made by carbon steel or stainless steel.But owing in the distribution well elevator pump is installed usually; Therefore when elevator pump needs repairing for a certain reason; Then need telescoping valve to have the effect of two way sealed; Can prevent that sealing pours in down a chimney, can prevent that again water in the secondary precipitating tank from leaking in the blowoff chamber, makes the attendant can in blowoff chamber, safeguard elevator pump on the spot.
Seal ring as shown in Figure 3, that the telescoping valve seal arrangement of existing technology has only an inner edge to be bent upwards can only prevent that therefore the water of outside from getting into barrel bore, and the water capacity of barrel bore is prone to flow out the outside, can not effectively realize two way sealed.
Summary of the invention
The purpose of this invention is to provide a kind of telescoping valve, can prevent that the water in the blowoff chamber from pouring in down a chimney, can prevent that again water in the secondary precipitating tank from leaking in the blowoff chamber, can effectively realize two way sealed.
For solving the problems of the technologies described above; Telescoping valve of the present invention; Comprise urceolus, can in urceolus, make the adjusting tube of slide relative up and down; Be provided with the seal arrangement that the upper sealing ring that is bent upwards by flange, inner edge and pressing plate are formed in the urceolus end, it is characterized in that: between said upper sealing ring and flange, also establish the reclinate lower sealing ring of an inner edge.
The such structure that adopts, upper sealing ring and lower sealing ring cooperatively interact, and can realize the two way sealed of sleeve; The upper sealing ring inner edge is bent upwards, the downwarping of lower sealing ring inner edge; Between two seal ring inner edges, just become along regulating the tube excircle to oil storage tank; Can storing lubricating oil in oil storage tank, can prevent that the water in the blowoff chamber from pouring in down a chimney, can prevent that again water in the secondary precipitating tank from leaking in the blowoff chamber; And reduce seal ring and regulate wearing and tearing between the tube, sealability is better.
As improvement, between said upper sealing ring and lower sealing ring, be provided with pad.Be provided with pad upper and lower seal ring is cut off, prevent to produce and disturb.
As further improvement, between described lower sealing ring and flange, be provided with offset plate.Offset plate is set can makes reclinate lower sealing ring have bigger bending radius, can in oil storage tank, store more lubricating oil, sealing effect is better.

Embodiment
Shown in Fig. 1, Fig. 2 telescoping valve structural representation of the present invention; Structural sleeve valve of the present invention comprises urceolus 1, regulates tube 2, screw mandrel 20 and hoist 21; Regulate the external diameter of tube 2 external diameters less than urceolus 1; Urceolus 1 is inserted in regulates tube 2, and under the driving of hoist 21 and screw mandrel 20, adjusting tube 2 urceolus 1 is relatively done relative movement up and down.Be provided with seal arrangement 22 in urceolus 1 upper end portion; Seal arrangement 22 comprises flange 3, packing ring 9, lower sealing ring 8, pad 7, upper sealing ring 4, pressing plate 5 and bolt 6; The external diameter of flange 3 internal diameters and urceolus 1 is suitable and be welded on the urceolus 1, bolt 6 flange 3, packing ring 9, lower sealing ring 8, pad 7, upper sealing ring 4, pressing plate 5 be linked together.The outer surface of regulating tube 2 contacts with the inner peripheral surface of upper sealing ring 4 and lower sealing ring 8, is divided in urceolus 1 inside with at urceolus 1 top two-part regulating tube 2, thus the sealability of realization seal arrangement 22.Upper sealing ring 4 inner edges are bent upwards, lower sealing ring 8 inner edge downwarpings; Between two seal ring inner edges, just become along regulating the tube excircle to oil storage tank 10; Can storing lubricating oil in oil storage tank 10, reduce seal ring and regulate the wearing and tearing between the tube 2, can prevent that the water in the blowoff chamber from pouring in down a chimney; Can prevent that again water in the secondary precipitating tank from leaking in the blowoff chamber, sealability is better.Between said upper sealing ring 4 and lower sealing ring 8, be provided with pad 7, upper sealing ring 4, lower sealing ring 8 are cut off, prevent to produce and disturb.Be provided with packing ring 9 between lower sealing ring 8 and the flange 3, can make reclinate lower sealing ring 8 have bigger bending radius, can in oil storage tank 10, store more lubricating oil, sealing effect is better.
Claims (3)
1. telescoping valve; Comprise urceolus (1), can in urceolus (1), make the adjusting tube (2) of slide relative up and down; Be provided with the seal arrangement that the upper sealing ring (4) that is bent upwards by flange (3), inner edge and pressing plate (5) are formed in urceolus (1) end, it is characterized in that: between said upper sealing ring (4) and flange (3), also establish the reclinate lower sealing ring of an inner edge (8).
2. telescoping valve according to claim 1 is characterized in that: between said upper sealing ring (4) and lower sealing ring (8), be provided with pad (7).
