Description
Technical Field
This novel access structure that belongs to, concretely relates to Y type stop valve body lumen export access structure.
Background
The Y-shaped stop valve is a structural type of the stop valve, a middle cavity of a valve body forms an inclination angle of 45 degrees with a channel, and the Y-shaped stop valve has the characteristics of a linear flow channel and high flow capacity. The flow capacity of the Y-shaped stop valve is related to the flow passage structure of the valve body, and an inlet passage, a valve seat and an outlet passage are generally designed into basically equal flow cross sections (hereinafter referred to as equal cross sections), but researches show that the equal cross section design limits the flow capacity of the valve and cannot achieve large flow capacity; studies have also found that the main factors affecting the flow-through capacity are: valve seat inlet and outlet shape, valve seat inlet and outlet area, middle cavity and outlet channel shape and area, and valve seat position. Wherein the shape and area of the lumen outlet channel are critical factors affecting the flow-through capacity. The existing channel constant-section design has the defect that the flow capacity is limited, and the flow capacity cannot be continuously improved.
SUMMERY OF THE UTILITY MODEL
The content of this novel is to prior art's defect, provides a cavity export passageway structure in Y type stop valve body.
This is novel to realize like this: the utility model provides a Y type stop valve body lumen outlet passage structure, includes the valve body, sets up the disk seat in the valve body, the one end and the inlet channel intercommunication of disk seat, the other end and the outlet channel of disk seat together with outlet channel.
According to the Y-shaped stop valve body middle cavity outlet channel structure, the middle cavity is arranged on the valve seat, one end of the middle cavity is communicated with the inlet channel, and the other end of the middle cavity is communicated with the outlet channel.
The cavity outlet channel structure in the valve body of the Y-shaped stop valve is characterized in that the outlet channel is provided with a guide rib.
The outlet channel structure of the cavity in the valve body of the Y-shaped stop valve is characterized in that the diameter of the cavity is d.
According to the outlet passage structure of the middle cavity of the valve body of the Y-shaped stop valve, the included angle between the axial direction of the middle cavity and the valve seat is 45 degrees.
The cavity outlet channel structure in the valve body of the Y-shaped stop valve is characterized in that the flow area S of the valve seat FZ ＝πd 2 /4。
The outlet channel structure of the cavity in the valve body of the Y-shaped stop valve is characterized in that the outlet channel is an elliptical hole, the major axis of the ellipse is smaller than 2d, and the minor axis of the ellipse is smaller than d.
The cavity outlet channel structure in the valve body of the Y-shaped stop valve is characterized in that the major axis of the ellipse is transversely arranged.
This neotype effect that is showing is: the flow capacity of the valve is improved, and the amplification is about 18%.

Detailed Description
A middle cavity outlet channel structure of a Y-shaped stop valve body comprises a valve body 1, a middle cavity 2, an outlet channel 3, a guide rib 4, a valve seat 5 and an inlet channel 6,
wherein, the valve body 1, the middle cavity connects the inlet channel through the valve base, and link with outlet channel;
the bottom of the middle cavity 2 is provided with a valve seat and is connected with an outlet channel;
the outlet channel 3 is communicated with the middle cavity, and the shape and the area of the part, which is intersected with the middle cavity, determine the circulation capacity, which is the key of the novel device;
the guide rib 4 is arranged at the outlet channel in the middle cavity;
the valve seat 5 is positioned at the bottom of the middle cavity of the valve body, the diameter of a valve seat hole is d, and the flow area of the valve seat is the standard for designing a valve body flow passage and is also the standard and reference for adjusting an outlet passage structure;
an inlet passage 6, the front end of which is connected with the valve seat.
Realize this neotype structure technique:
the novel outlet channel structure is characterized in that the valve seat is used as a reference, the valve seat is used as a reference object to adjust the shape and the size, and the flow area of the outlet channel is enlarged.
1) Flow through valve seatArea S FZ ＝πd 2 (ii)/4, wherein: d is the valve seat orifice diameter, see fig. 1.
2) The shape of the outlet channel is adjusted to be an elliptical hole from a circular hole which is the same as that of the valve seat, the major axis of the ellipse is smaller than 2d, the minor axis of the ellipse is smaller than d, and d is the diameter of the valve seat hole.
3) When the flow area S of the outlet channel CK (the flow area without the guide rib) is 1.2 to 1.8 times of the flow area of the valve seat, namely S CK ＝(1.2～1.8)S FZ And the flow capacity is better.
When S is CK Close to 1.5S FZ The flow-through performance reaches an optimum value.
The outlet channel in the middle cavity is provided with a guide rib.
In addition, the present application also includes the following,
1. the valve body middle cavity is connected with the inlet channel through the valve seat and is connected with the outlet channel.
2. The bottom of the middle cavity is provided with a valve seat and is connected with an outlet channel.
3. The outlet channel is communicated with the middle cavity, and the shape of the part, which is intersected with the middle cavity, is approximately elliptical; when the outlet passage flow area S CK (the flow area without the guide rib) is 1.2 to 1.8 times of the flow area of the valve seat, namely S CK ＝(1.2～1.8)S FZ And the flow capacity is better. When S is CK Close to 1.5S FZ The flow-through performance reaches an optimum value.
4. The guide rib is arranged at the outlet channel in the middle cavity.
