Abstract

The utility model discloses a valve baffle which comprises an annular baffle body (4), a long rod end (3) connected with a handle and a short rod end (5) connected with a valve body. The axis of the long rod end (3), a center line of the baffle body (4) and the axis of the short rod end (5) are the same axis. The long rod end (3), the short rod end (5) and the baffle body (4) are integrally formed in a die cast mode. Two axial planes (1) symmetrically distributed are arranged on the outer circumferential wall on the end portion of the long rod end (3), and two matched planes are arranged at the connection portion of the handle and the long rod end (3) correspondingly. Due to the fact that the plane contact and limit structure is adopted, the gap at the connection position of the long rod end and the handle is greatly reduced. On one hand, abrasion between the valve baffle and the execution mechanism caused by collision is reduced; on the other hand, energy dissipation is reduced.

Description

Spigot baffle

Technical field

The utility model relates to the technical field of valve, is specifically a kind of spigot baffle.

Background technique

In the structure of some valve forms, use sometimes spigot baffle, it is arranged in valve body, and upper end is the stock end being connected with handle, and lower end is the quarter butt end being connected with valve body, and centre is circular baffle body.In the spigot baffle of prior art, the end of stock end is connected with handle by flat key, and meanwhile, stock end and quarter butt end are all to weld together with baffle body.Therefore there is following shortcoming in the spigot baffle of this structure:

1), because stock end is connected with handle by flat key, therefore, in flat key joint, the gap of existence is larger, thus when operation on the one hand can and handle between because collision produces wearing and tearing, also increased on the other hand the loss of energy;

2) in addition, stock end and quarter butt end and baffle body are welded, and therefore, its cost of production is higher, meanwhile, and the poor dimensional precision of product.

Model utility content

Technical problem to be solved in the utility model is, provides a kind of fit up gap little, thereby reduces the wearing and tearing of component and the loss of energy, and the low spigot baffle of cost of production.

For solving the problems of the technologies described above, the spigot baffle that the utility model provides, the stock end that comprise circular baffle body, is connected with handle is same axis with the quarter butt end being connected with valve body, the axis of the axis of stock end, the center line of baffle body and quarter butt end; Described stock end, quarter butt end and baffle body are the integral body that die cast forms, and, on the end outer circle wall of stock end, there are two symmetrical axial planes, correspondingly handle has with the joint of stock end two planes that match.

The changeover portion of described each axial plane and stock end outer circle wall is tapered plane, and the angle of tapered plane and axial plane is 45 °.

Adopt after above structure, the utility model compared with prior art, has the following advantages:

1) owing to having adopted plane contact and spacing structure, therefore, greatly reduced the gap of the joint of stock end and handle, like this, reduced on the one hand and handle between the wearing and tearing that produce due to collision, also reduced on the other hand the loss of energy;

2) after stock end, baffle body and quarter butt end is one-body molded by die casting, guarantee the axis of stock end, the axis of the center line of baffle body and quarter butt end is same axis on the one hand, also reduced on the other hand cost of production;

3) in addition, axial plane is designed to after tapered plane with the changeover portion that is connected of the outer circle wall of stock end, has greatly reduced the shearing stress of this connection changeover portion, guaranteed intensity, avoid occurring the phenomenon of fracture.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Structural representation from the spigot baffle shown in Fig. 1 and Fig. 2, it comprises circular baffle body 4, the stock end 3 being connected with handle and the quarter butt end 5 being connected with valve body, and the center line of the axis of stock end 3, baffle body 4 and the axis of quarter butt end 5 are same axis; The integral body that described stock end 3, quarter butt end 5 and baffle body 4 form for die cast, and, on the end outer circle wall of stock end 3, have two symmetrical axial planes 1, correspondingly handle has with the joint of stock end 3 two planes that match.

Described each axial plane 1 is tapered plane 2 with the changeover portion of stock end 4 outer circle walls, and tapered plane 2 is 45 ° with the angle of axial plane 1.

Claims

1. a spigot baffle, the stock end (3) that comprise circular baffle body (4), is connected with handle and the quarter butt end (5) being connected with valve body, the center line of the axis of stock end (3), baffle body (4) and the axis of quarter butt end (5) they are same axis; It is characterized in that: the integral body that described stock end (3), quarter butt end (5) and baffle body (4) form for die cast, and, on the end outer circle wall of stock end (3), have symmetrical two axial planes (1), correspondingly handle has with the joint of stock end (3) two planes that match.

2. spigot baffle according to claim 1, it is characterized in that: described each axial plane (1) is tapered plane (2) with the changeover portion of stock end (4) outer circle wall, and tapered plane (2) is 45 ° with the angle of axial plane (1).
