Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

Known by fig. 1 to 4, slag discharging valve, including valve body 1, install valve plate 2 in the

valve body

1, 1 top of valve body is connected with valve gap 3, it has valve rod 4 to run through in the

valve gap

3, 4 lower extremes of valve rod and 2 fixed connection of valve plate, 3 tops of valve gap are equipped with the drive arrangement 5 of being connected with valve rod 4, be equipped with the sealing washer 6 that sets up with the laminating of valve plate 2 in the valve body 1, valve plate 2 deviates from sealing washer 6 one side and is equipped with first inclined plane 7, be equipped with the recess 8 that is located 2 bottoms of valve plate in the valve body 1, recess 8 is equipped with the sealed lid 9 that articulates on valve body 1 outward, be equipped with wedge 10 on the valve body 1, be equipped with on the wedge 10 with first inclined plane 7 complex second inclined plane 11, wedge 10 is at 1 internal horizontal slip of valve body, wedge 10 is.

The driving device 5 is a manual device.

And chamfers are arranged on the inner side and the outer side of the sealing ring 6.

And a sealing gasket is arranged between the sealing cover 9 and the groove 8.

The hinged end of the sealing cover 9 and the valve body 1 is positioned at one side of the valve body 1, which is internally provided with a wedge-shaped block 10, and the other end of the sealing cover 9 is fixed on the valve body 1 through a screw 14.

The inner end of the wedge block 10 is connected to the valve body 1 through a spring 13, and the spring 13 pushes the wedge block 10 outwards.

The limiting rod 12 is located above one end, hinged to the valve body 1, of the sealing cover 9 after sliding, the sealing cover 9 cannot rotate, and after the limiting rod 12 slides away from the sealing cover 9, the sealing cover 9 can rotate.

When the utility model is used in a concrete way,

when this device is in the state of opening, drive arrangement 5 drives valve rod 4 and rises for valve plate 2 breaks away from the contact with 1 inner chamber bottom sealing washer 6 of valve body, open 1 interior passageway of valve body, the sediment powder passes through in the valve body 1, after valve plate 2 rises, wedge 10 stretches out under the effect of spring 13 from the valve body 1 in, gag lever post 12 removes to sealed 9 top positions of covering, prevent sealed lid 9 and rotate, sealed lid 9 can not be opened under operating condition promptly, open sealed lid 9 when avoiding normal work and influence the normal discharge of sediment powder.

When the slag powder does not need to be discharged, the driving device 5 controls the valve rod 4 to descend, the valve rod 4 drives the valve plate 2 to move downwards, the lower end of the valve plate 2 enters the groove 8, a sealing space is formed after one side of the valve plate 2 is contacted with the sealing ring 6, the effect of blocking the flow of the slag powder is achieved, the valve body 1 is provided with a sealing surface matched with the valve plate 2 above the wedge-shaped block 10, when the valve plate 2 moves to the bottom end, the sealing surface is contacted with the valve plate 2, a sealed cavity is formed inside the groove 8, the wedge-shaped block 10 is pushed to move towards the valve body 1 after the first inclined surface 7 on the valve plate 2 is contacted with the second inclined surface 11 of the wedge-shaped block 10, the limiting rod 12 is far away from the sealing cover 9, at the moment, the sealing cover 9 can be opened.

Be equipped with the packing chamber that is located the valve rod 4 outside above valve gap 3, inside packing plays the effect of striking off valve rod 4, guarantees the inside sealed effect of valve body 1.

The sealing surface above the wedge-shaped block 10 can achieve the sealing effect after contacting the valve plate 2, and can also enable slag powder to be smoothly discharged in the working process.

The sealing cover 9 is fixed on the valve body 1 by a screw 14, and a sealing gasket is arranged between the sealing cover and the valve body 1, so that the sealing of the interior of the sealing cover is ensured, and the sealing cover is convenient to remove.

Compared with the prior art, the utility model, following beneficial effect has: can be under the condition that does not influence row sediment normal clear up the accumulational sediment powder in the valve body, avoid its long-time corrosion damage to the valve body, prolong the life of sediment valve.
