Abstract

The utility model discloses a sealing impact forging welding sluice valve. The utility model is characterized in that a shell cover and a medium diameter pipe are welded integrally, and an arc-shaped bottom cover is welded at the lower port of the medium diameter pipe. The utility model has the advantages of light weight and non-leakage and is especially suitable for being used in crossover pipes.

Description

Closed throttle valve made up by impacting forging and welding

The utility model belongs to gate valve, is a kind of enclosed throttle valve made up by impacting forging and welding.

For the casting gate valve volume that overcomes industrial use in the past big, waste material, the deficiency that the inner chamber turbidity test are difficult to be up to state standards, people have worked out the valve of welding fabrication, as the patent No. 91209730.2 " throttle valve made up by impacting forging and welding ", the inner chamber turbidity test of this gate valve have been better than national A grade standard, save material, it is a kind of Updated product of gate valve, but also contain middle flange in its structure, valve gap and valve body are coupled together by middle flange, this structure can be along with the wearing and tearing in using, sealing gasket fatigue also can produce seepage, influences product quality stability.

The purpose of this utility model is, the closed throttle valve made up by impacting forging and welding of a kind of valve gap and the direct welding fabrication of valve body is provided.

The utility model can be realized with following mode:

Closed throttle valve made up by impacting forging and welding is made up of valve body, last bottom flange, flashboard, guide rail and handwheel, middle footpath pipe, path tube and bottom constitute valve body, end socket, filler chamber constitute bottom flange, it is characterized in that: described end socket and middle footpath pipe directly are welded as a whole, the lower end mouth place of footpath pipe during the arc bottom is welded in.

Valve gap of the present utility model and valve body are welded to connect, and have removed middle flange, and valve weight is lighter, save material, have also alleviated the load of pipeline, and be non-leakage, steady quality.

Fig. 1 is the utility model structural representation.

Embodiment of the present utility model is described in detail in detail in conjunction with the accompanying drawings:

As shown in the figure, middle footpath is managed 5 and is welded with path tube 6,11 respectively, form the welding track that passes through mutually, 5 lower end mouth place was managed in the footpath during arc bottom 9 was welded in, end socket 4 directly is welded as a whole with middle footpath pipe 5, end socket 4, filler chamber's 3 welding, constitute bottom flange, middle footpath pipe 5, path tube 6,11 and bottom 9 constitute bottom flange, and the utility model has removed middle flange, not only alleviated the weight of product, and avoided the tired seepage of sealing gasket, and 1 is handwheel among the figure, the 2nd, and valve rod, flashboard 12 inserts in the guide rail 8, and the 7, the 10th, flange.

Claims

1, a kind of closed throttle valve made up by impacting forging and welding, form by valve body, last bottom flange, flashboard, guide rail and handwheel, middle footpath is managed (5), path tube (6), (11) and bottom (9) and is constituted valve body, end socket (4), filler chamber (3) constitute bottom flange, it is characterized in that: described end socket (4) directly is welded as a whole with middle footpath pipe (5), the lower end mouth place of footpath pipe (5) during arc bottom (9) is welded in.
