Description

Stop valve body

Technical Field

The utility model relates to the technical field of valves, concretely relates to stop valve body.

Background

The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so when the valve is closed, pressure must be applied to the valve clack to force the sealing surface not to leak. When the medium enters the valve from the lower part of the valve clack, the resistance to be overcome by the operating force is the friction force between the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod buckling can occur.

The existing stop valve generally comprises a transverse valve body and a vertical valve body which are vertically arranged, the whole stop valve is of a T-shaped structure, a medium channel is arranged in the stop valve, and a valve seat is arranged in the medium channel. When the valve is installed in a non-horizontal mode, the valve clack deviates from the valve seat due to the action of gravity and is difficult to center, and therefore the using effect of the valve is affected.

SUMMERY OF THE UTILITY MODEL

To the not enough in the background art, the utility model provides a stop valve body.

The utility model adopts the technical proposal that: the utility model provides a stop valve body, includes the horizontal valve body and the vertical valve body of perpendicular setting, be equipped with the inlet channel and the exit channel of intercommunication in the horizontal valve body, be equipped with partition wall and disk seat between inlet channel and the exit channel, partition wall and disk seat structure as an organic whole, the vertical valve body in be equipped with the valve clack installation cavity, the disk seat upwards extend and have the direction flaring, contained angle gamma between the side of direction flaring and the vertical axis is 25-35, horizontal valve body and vertical valve body between be equipped with the strengthening rib.

Further, the angle γ between the side of the pilot flare and the vertical axis is 30 °.

Further, the partition walls comprise an inlet partition wall and an outlet partition wall, and included angles beta between the inlet partition wall and the axis of the transverse valve body and included angles beta between the outlet partition wall and the axis of the transverse valve body are 120 degrees.

Furthermore, connecting flanges are integrally formed at the upper end of the vertical valve body and the two ends of the transverse valve body.

Further, the thickness of the outlet partition wall is larger than that of the inlet partition wall.

The utility model has the advantages that: the utility model discloses a set up the direction flaring on the disk seat, play the guide effect, avoid the valve clack to take place the skew under the action of gravity, effectively improve valve result of use.

In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided.

The present invention will be described in further detail below with reference to the drawings.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a transverse valve body; 2. a vertical valve body; 3. an inlet channel; 4. an outlet channel; 5. a valve seat; 6. a valve clack installation cavity; 7. guiding flaring; 8. an included angle gamma; 9. reinforcing ribs; 10. an inlet partition wall; 11. an outlet partition wall; 12. the included angle beta; 13. and connecting the flanges.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a stop valve body.

In this embodiment, referring to fig. 1, this stop valve body, including the perpendicular horizontal valve body 1 and the vertical valve body 2 that set up, be equipped with the inlet channel 3 and the exit channel 4 of intercommunication in the horizontal valve body 1, be equipped with partition wall and disk seat 5 between inlet channel 3 and the exit channel 4, partition wall and disk seat structure as an organic whole, vertical valve body 2 in be equipped with valve clack installation cavity 6, disk seat 5 upwards extend and have direction flaring 7, contained angle gamma 8 between the side of direction flaring 7 and the vertical axis is 25-35, horizontal valve body and vertical valve body between be equipped with strengthening rib 9.

Among the above-mentioned technical scheme, through set up the direction flaring on the disk seat, play the guide effect, avoid the valve clack to take place the skew under the action of gravity, effectively improve valve result of use.

In addition, because the holistic "T" type structure of stop valve body forms the stress of corner between its horizontal valve body and the vertical valve body and too concentrates, long-term the use leads to warping easily and the problem that sealing performance descends appears, the utility model discloses a be equipped with the strengthening rib between horizontal valve body and the vertical valve body, improve its mechanical strength, reduce the influence that the valve body received stress.

Preferably, the angle γ between the side of the pilot flare and the vertical axis is 30 °.

Specifically, the partition walls comprise an inlet partition wall 10 and an outlet partition wall 11, and included angles beta 12 between the inlet partition wall and the outlet partition wall and the axis of the transverse valve body are 120 degrees; the upper end of the vertical valve body and the two ends of the transverse valve body are integrally formed with connecting flanges 13; the thickness of the outlet partition wall is larger than that of the inlet partition wall. The connecting flange is convenient to be connected with other pipelines.

The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited to the embodiments, and any modifications that utilize the inventive concepts are intended to be included within the scope of the appended claims.
