Compared with prior art, the sodium filling valve of large diesel engine according to the present invention has the following beneficial effects: that this is heavy
The valve hollow space of the sodium filling valve of diesel engine consists of two parts, and bar portion is hollow and head is hollow with the shape.Hollow part
Temperature and heat transfer position, especially head of the selection when fully taking into account valve operation profile-followed hollow structure, greatly
Hollow volume and heat transfer area are increased, valve temperature can be effectively reduced, and then reduce the abrasion of valve.Do not have to adopt in this way
The requirement for reducing abrasion, the rise of the valve price avoided can also be reached with advanced material；Valve divides bottom plugging plate, in bar portion
Three sections of dead band, bar portion solid-section, are welded twice.Bar portion hollow section is welded to using bottom plugging plate, is to strictly protect
Demonstrate,prove head profile-followed hollow shape and hollow volume.The heat generated when welding is to reduce welding in two times is excessive, avoids
Sodium leakage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the sodium filling valve of large diesel engine according to an embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, the specific structure of the sodium filling valve of large diesel engine according to the preferred embodiment of the present invention includes:
Bar portion solid-section 3, bar portion hollow section 2 and bottom plugging plate 1.Wherein, the valve hollow space of bar portion hollow section 2 is hollow by bar portion
With head hollow two parts composition with the shape, temperature and heat transfer position when the selection of hollow part fully takes into account valve operation
It sets, especially the profile-followed hollow structure on head, significantly increases hollow volume and heat transfer area, valve can be effectively reduced
Temperature, and then reduce the abrasion of valve.Do not have to reach the requirement for reducing abrasion, the valve avoided using advanced material so yet
The rise of price；Bottom plugging plate, bar portion hollow section, three sections of bar portion solid-section be welded in two times, using bottom plugging plate
It is welded to bar portion hollow section, is for strict guarantee head profile-followed hollow shape and hollow volume.In two times welding be in order to
It is excessive to reduce the heat generated when welding, sodium is avoided to reveal.
Specifically, bar portion hollow section 2 includes: bar portion and the head positioned at the one end of the rod, and bar portion has bar portion hollow
21, bar portion hollow 21 be it is cylindric, it is central axial to be laid in bar portion；Head has head profile-followed hollow 22, and head is hollow with the shape
22 for profile-followed horn-like in head, one end is connected to the bar portion of bar portion hollow 21.The profile-followed hollow structure on head, greatly
Hollow volume and heat transfer area are increased, valve temperature can be effectively reduced, and then reduce the abrasion of valve.Do not have to adopt in this way
The requirement for reducing abrasion, the rise of the valve price avoided can also be reached with advanced material.
