Abstract
The utility model discloses a core iron of a four-way reversing valve. The core iron comprises a core iron body (1) and a positioning plate (2); a kidney-shaped through hole (3) penetrates the positioning plate (2); the positioning plate (2) is positioned on the end face of the core iron body (1); and the positioning plate (2) and the core iron body (1) form a whole. The core iron of the four-way reversing valve can ensure that the positioning plate (2) is perpendicular to the end face of the core iron body (1) and the distance between the kidney-shaped through hole (3) of the positioning plate (2) and the end face of the core iron body (1) is equal to the specified size.
Description
Technical field
The utility model relates to a kind of valve body structure, specifically is a kind of core iron of four-way change-over valve.
Background technique
Four-way change-over valve comprises valve body and the sliding fit core iron in valve body, and an end face riveted joint of core iron has a positioning plate, is penetrated with waist typed through hole on the positioning plate.Because positioning plate is riveted on the core iron; And the riveting process precision is lower, can't guarantee that positioning plate is vertical with the end face of core iron, and then can't guarantee that also the waist typed through hole of positioning plate and the distance of core iron end face meet design requirement; This will cause core iron slippage in valve pocket to have some setbacks; The poor sensitivity of whole selector valve switching-over, the product size of batch process is inconsistent, and riveting process manufacturing efficiency is low.
Summary of the invention
The technical problem that the utility model will solve is, provides the distance of the end face of a kind of waist typed through hole that can guarantee positioning plate and positioning plate vertical with core iron body end face and core iron body to equal the core iron of the four-way change-over valve of given size.
The technical solution of the utility model is; A kind of core iron with four-way change-over valve of following structure is provided, and it comprises a core iron body and a positioning plate, is penetrated with a waist typed through hole on the positioning plate; Positioning plate is positioned at the end face of core iron body, and positioning plate and core iron body are one.
After adopting above structure, the core iron of the utility model four-way change-over valve compared with prior art has the following advantages:
Because positioning plate and core iron body are one, promptly positioning plate and core iron body are the integrally casting moulding, like this; Omit the step of riveted joint positioning plate, simplified operation, improved manufacturing efficiency; And the more important thing is that can guarantee that like this positioning plate is vertical fully with the end face of core iron body, the distance of the end face of waist typed through hole and core iron body is equal to the size of designing requirement on the assurance positioning plate; So this selector valve switching-over is highly sensitive, and the size of producing in batches is unified.
As improvement, the distance of the end face of waist typed through hole and core iron body-fixed positioning plate is 6.5mm., like this, the sensitive reversing property of this four-way change-over valve is the highest.
Description of drawings
Fig. 1 is the plan structure schematic representation of the core iron of the utility model four-way change-over valve.
Fig. 2 is the sectional structure schematic representation of Fig. 1 along the A-A direction.
Shown in the figure 1, the core iron body, 2, positioning plate, 3, waist typed through hole, the distance between the end face of the length bisector of d, waist typed through hole and core iron body-fixed positioning plate.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2, the core iron of the utility model four-way change-over valve, it comprises a core iron body 1 and a positioning plate 2.Be penetrated with a waist typed through hole 3 on the positioning plate 2, positioning plate 2 is positioned at an end face of core iron body 1.Positioning plate 2 is an one with core iron body 1.Waist typed through hole 3 is 6.5mm with the distance of the end face of core iron body 1 stationary positioned plate 2.Specifically, be 6.5mm apart from d between the end face of the length bisector of waist typed through hole 3 and core iron body 1 stationary positioned plate 2.
Claims (2)
1. the core iron of a four-way change-over valve; It comprises a core iron body (1) and a positioning plate (2); Be penetrated with a waist typed through hole (3) on the positioning plate (2), it is characterized in that: positioning plate (2) is positioned at the end face of core iron body (1), and positioning plate (2) is an one with core iron body (1).
2. the core iron of four-way change-over valve according to claim 1 is characterized in that: waist typed through hole (3) is 6.5mm with the distance of the end face of core iron body (1) stationary positioned plate (2).
