Embodiment
The present invention will be further described below in conjunction with Figure of description.
Referring to Fig. 1, one-way valve of the present invention has two kinds of structural types, it is just like shown in the label among Fig. 11, be to comprise valve seat 2, sealed valve core 3, pressure spring 4, valve gap 5, offer valve opening 6 on the valve seat 2, valve gap 5 is connected on the valve seat 2, and pressure spring 4 supports between sealed valve core 3 and valve gap 5 and by valve gap 5 and makes sealed valve core 3 draw close to valve opening 6, outlet 7 is set on the valve gap 5, and sealed valve core 3 has the coniform sealed department 9 of contact valve opening 6 port edges.Can reach the better seal effect by this coniform sealed department 9 with contacting of valve opening 6 port edges, be difficult for leaking.Further, sealed valve core 3 has a guide rod 10 that extends back from sealed department 9, has a guide hole 11 on the valve gap 5, and guide rod 10 is positioned at guide hole 11, so that sealed valve core 3 is avoided skew to sealed valve core 3 guiding when movable.Pressure spring 4 is enclosed within on the guide rod 10, and it is even to apply elastic force, compact structure.Putting between valve gap 5 and the valve seat 2 has seal ring 12, guarantees sealing.
The another kind of structural type of one-way valve of the present invention is shown in the label among Fig. 1 01, comprise valve seat 02, sealed valve core 03, pressure spring 04, valve gap 05, offer valve opening 06 on the valve gap 05, valve gap 5 is connected on the valve seat 02, pressure spring 04 supports between sealed valve core 03 and valve gap 05 and by valve seat 02 and makes sealed valve core 03 draw close to valve opening 06, import 08 is set on the valve gap 05, and sealed valve core 3 has the coniform sealed department 09 of contact valve opening 6 port edges.Can reach the better seal effect by this coniform sealed department 09 with contacting of valve opening 06 port edge, be difficult for leaking.Further, sealed valve core 03 has a guide rod 010 that extends back from sealed department 09, has a guide hole 011 on the valve seat 02, and guide rod 010 is positioned at guide hole 11, so that sealed valve core 03 is avoided skew to sealed valve core 03 guiding when movable.Pressure spring 04 is enclosed within on the guide rod 010, and it is even to apply elastic force, compact structure.Putting between valve gap 05 and the valve seat 02 has seal ring 012, guarantees sealing.
Shown in Figure 1 is that the one-way valve of two kinds of structures of the present invention is applied in a schematic representation on the raw water service pump, in the figure, the valve seat 2 of the one-way valve of two kinds of structures of the present invention and 02 and the pump housing of raw water service pump make one, when pump housing upper piston move down make the pump chamber volume increase, when pressure reduces, under the pressure difference effect in the pump chamber pressure and the external world, sealed valve core 03 is pushed open from valve opening 06, and sealed valve core 3 is more reliable with valve opening 6 shutoff, thereby can fluid such as water be sucked pump chamber by import 07; Make when pump housing upper piston moves up that the pump chamber volume reduces, when pressure increases, under the pressure difference effect in the pump chamber pressure and the external world, sealed valve core 3 is pushed open from valve opening 6, and sealed valve core 03 is more reliable with valve opening 06 shutoff, thereby can fluid in the pump chamber such as water be transferred out by exporting 7.In the working procedure of this raw water service pump, can reach the better seal effect by coniform sealed department with contacting of valve opening port edge, be difficult for leaking.
Fig. 2 is applied in schematic representation on the steam ouput of a Heating core (Heating core 13 is heater 15 to be set and water intake 16 and steam ouput 17 are being set on the housing 14) with 1 one-way valve of label among Fig. 1 in the inner space of housing 14: with valve seat 2 with the housing 14 of Heating core 13 built in, promptly utilize housing 14 to make valve seat 2, with the steam ouput 17 of Heating core 13 as valve opening 6, then when transporting water stream is through heater 15 heating generation steam in Heating core 13 by water intake 16, because pressure spring 4 is pressed in sealed valve core 3 elasticity on the valve opening 6 (being steam ouput 17), therefore valve opening 6 is temporarily by shutoff and can not steam discharge, along with producing increasing of steam in the Heating core 13, vapor pressure raises, until the elastic force that can overcome pressure spring 4 and sealed valve core 3 can be pushed open from valve opening 6 and opened valve opening 6, released vapour, so the steam that discharges has certain pressure (therefore this pressure can determine the pressure of valve opening 6 released vapours by the pressure spring of selecting different elastic force for use by the elastic force decision of pressure spring 4) and this pressure can keep stable; And, just in case Heating core 13 stops up, can the steam in the Heating core 13 be discharged pressure release by one-way valve 1, avoid explosion risk, jeopardize personal safety.Owing to can reach the better seal effect with contacting of valve opening port edge by coniform sealed department, be difficult for leaking, guarantee that the vapor pressure that discharges is stable.
The sealed valve core that core of the present invention is with valve opening cooperates has the coniform sealed department that contacts the valve opening port edge.Especially, sealed valve core has a guide rod that extends back from sealed department.Therefore; though above introduced application example of the present invention; but can not be interpreted as limiting the scope of the invention; in every case possessed sealed valve core and had the structure of the coniform sealed department of contact valve opening port edge, all can be considered according to claim of the present invention and fall into protection scope of the present invention.
