Description
Technical field
The present invention relates to a kind of water stop bolt, relate in particular to the water stop bolt of the preferable sealability of a kind of tool.
Background technique
Water stop bolt is to be used in cooling of mould water channel or the heating system, the flow direction of water channel is played the metal parts of wad act.In order to control the flow direction of water channel effectively, industry has proposed higher requirement to the sealability of water stop bolt, in addition, when can water stop bolt be operated in environment its sealability that remain valid of following time that colds and heat succeed each other, also be the major criterion whether check water stop bolt performance meets the requirements.Yet, existing water stop bolt in use, its sealability is difficult to reach desirable usually and requires or standard, correspondingly, water stop bolt water leakage phenomenon may occur in use, brings negative effect to production, and may cause the product yield to descend.
Summary of the invention
In view of this, be necessary to provide the water stop bolt of the preferable sealability of a kind of tool.
A kind of water stop bolt, it comprises that one is installed ring and a seal valve.This installation ring is offered one first hole and second hole that connects with this first hole.This first hole and this place of connecting, second hole form a ladder, and this first hole has one first radius at this ladder place.The radius in this second hole is by reducing gradually away from the direction of this first hole to contiguous this first hole, and this second hole has one second radius at this ladder place, and this first radius is greater than second radius.The sealing valve has an Elastic buckle portion and a pressure section that is connected with this Elastic buckle portion.This Elastic buckle portion and this first hole are complementary and are contained in this first hole.This pressure section and this second hole is complementary and the outer surface of this pressure section compresses the inner side surface in this second hole.
With respect to prior art, the seal valve that water stop bolt provided by the present invention comprised has Elastic buckle portion and pressure section, during work, on the one hand, this Elastic buckle portion buckle is housed in first hole that ring is installed, and it not only can play blocking action but also can prevent that this Elastic buckle portion breaks away from this installation ring current; On the other hand, this pressure section compresses this installation ring, thereby further current is played blocking action, and therefore this water stop bolt has preferable sealability.

Embodiment
Below will the present invention is described in further detail with specific embodiment.
See also Fig. 1 and Fig. 2, the embodiment of the invention provides a kind of water stop bolt 100, and it comprises that one is installed ring 10 and a seal valve 20.
This installation ring 10 roughly is hollow cylindrical, and one first hole 12 and one second hole 14 are offered in its center.This first hole 12 connects with this second hole 14, and its place of connecting forms a ladder 16.In the present embodiment, this first hole 12 is coniform, and its radius is by becoming big gradually away from one of second hole 14 to contiguous this second hole 14 one, and wherein, this first hole 12 has one first radius D1 with these second hole, 14 intersections.This second hole 14 also is coniform, and its radius is by reducing gradually away from one of this first hole 12 to contiguous this first hole 12 one, and wherein, this second hole 14 has one second radius D2 with these first hole, 12 intersections.This first radius D1 is greater than the second radius D2, thereby forms this ladder 16.The outer ring of this installation ring 10 offers screw thread 18, and this installation ring 10 can be locked in the water route of mould by this screw thread 18 in use.
The outer side surface shape of the Elastic buckle ring 222 of this Elastic buckle portion 22 and this are installed first hole, 12 approximate match of ring 10, and the profile of this pressure section 24 and this are installed second hole, 14 approximate match of ring 10.In the present embodiment, form a gap 26 between this Elastic buckle ring 222 and this pressure section 24.Certainly, also can not form this gap 26 between this Elastic buckle ring 222 and this pressure section 24, promptly sealing valve 20 roughly is a cone, and its external diameter is increased to this pressure section 24 gradually by this Elastic buckle portion 22.
During work, sealing valve 20 is locked in first hole 12 and second hole 14 that ring 10 is installed.In the present embodiment, this installation ring 10 selects for use brass as material, sealing valve 20 selects for use steel as material, on the one hand, it is number (Coefficient of Thermal Expansion that brass has higher relatively thermal expansion, CTE), when this installation ring 10 is locked in the water route of mould and falls on the water temperature in the water route, water route thereby this installation ring 10 can suitably expand in the sealed mold more preferably, on the other hand, brass has preferable anti-corrosion capacity, and it can effectively prevent to corrode between this installation ring 10 and the sealing valve 20, the phenomenon that causes water stop bolt 100 to wear out.
Be understandable that this first hole 12 can also be other shape,, be not limited to present embodiment as cylindric etc.
Please one rise and consult Fig. 3, during installation, can be by using external tool (figure does not show) pulling seal valve 20 so that its second hole 14 and first hole 12 of aiming at installation ring 10 lock in this installation ring 10.This external tool specifically can be a grab, thereby it can stretch into the end face 2260 that this attachment hole 228 hooks counterbore 226, and then sealing valve 20 can be drawn in this installation ring 10 along the direction shown in Fig. 3 arrow T.As shown in Figure 3, before Elastic buckle portion 22 enters first hole 12, conflict the respectively inner side surface in this second hole 14 of this Elastic buckle ring 222 and this pressure section 24.
Please further consult Fig. 4, make it when the direction shown in Fig. 3 arrow T moves when continuing pulling sealing valve 20, this Elastic buckle ring 222 will with ring 10 mutual extrusion are installed, this Elastic buckle ring 222 pressurizeds and to the compression of the side of contiguous this main part 220, thus slide in first hole 12 along the side in second hole 14.Be understandable that, when Elastic buckle ring 222 slips into first hole 12, on the one hand, because profile and this first hole, 12 approximate match of Elastic buckle ring 222, therefore, this Elastic buckle ring 222 elasticity discharge, thereby it is housed in to contact in first hole 12 and with this installation ring 10 and forms preferable seal action; On the other hand, the outer surface of this pressure section 24 will compress the inner side surface in second hole 14, and at this moment, the brass material that ring 10 is installed deforms under the compressing of pressure section 24 steel, thereby make this installation ring 10 and this pressure section 24 form interference fit, thereby further form seal action.In the present embodiment, can form a gap 26 between this Elastic buckle ring 222 and this pressure section 24.When the brass material of this installation ring 10 deformed, the ladder 16 of this installation ring 10 was in this gap 26 and be fastened between this Elastic buckle ring 222 and this pressure section 24.This ladder 16 can form further seal action with seal valve 20, and can prevent that sealing valve 20 breaks away from this installation ring 10.Because the Elastic buckle ring 222 of seal valve 20 seals to ring 10 is installed simultaneously with pressure section 24, and the ladder 16 between Elastic buckle ring 222 and the pressure section 24 can prevent that sealing valve 20 breaks away from this installation ring 10, therefore, the sealability of this water stop bolt 100 is effectively ensured.
Be noted that above-mentioned mode of execution only is better embodiment of the present invention, those skilled in the art also can do other variation in spirit of the present invention.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
