Abstract
The utility model discloses an abrasion-resistant anti-blockage slag discharge gate valve, which comprises a valve body, a valve cap, a valve rod, a hand wheel, a valve plate and a seal device. The abrasion-resistant anti-blockage slag discharge gate valve is characterized in that the valve body is in a combined structure and comprises a liquid inlet valve body and a liquid outlet valve body in connection through a fastener, adjacent end faces of the liquid inlet valve body and the liquid outlet valve body are provided with seal surfaces respectively, the valve plate is positioned between the two seal surfaces, the liquid outlet valve body is provided with a slag discharge runner positioned below the valve plate, and the runner is communicated with an inner cavity of the liquid outlet valve body. The abrasion-resistant anti-blockage slag discharge gate valve can avoid impurities from flushing the seal surfaces from the front, and sealing performance of the gate valve can be guaranteed for a long time.
Description
Technical field
The utility model relates to a kind of gate valve, belongs to valve technology field.
Background technique
Gate valve is widely used in fields such as chemical industry, metallurgy, hydraulic engineering, and existing gate valve comprises valve body, valve gap, valve rod, handwheel, flashboard and seal arrangement, and its valve body is monolithic construction, is provided with two sealing surfaces in the valve body, and flashboard is between two sealing surfaces; When gate valve was opened, flashboard rose, and flowing medium flows out; But when containing more impurity in the flowing medium, impurity washes away sealing surface with the front, not only causes sealing surface easy to wear; And when gate valve was closed, the impurity alluvial can't be discharged, and was prone to attached on the sealing surface; Stop up the flashboard passage, make flashboard not close and put in place, reduced the sealing of gate valve; And mostly the cross section of valve gap is square, and its intensity is lower.
The model utility content
The purpose of the utility model is the above-mentioned deficiency to existing technology, provides a kind of wear-resisting deslagging not have the obstruction gate valve, and it can avoid the impurity front to wash away sealing surface, and guarantees the sealability of gate valve for a long time.
For achieving the above object, the wear-resisting deslagging of the utility model does not have the obstruction gate valve, comprises valve body, valve gap, valve rod, handwheel, flashboard and seal arrangement; It is characterized in that said valve body is a fabricated structure; It comprises liquid entering hole valve body and the liquid outlet valve body that connects through fastening piece, and the adjacent face of liquid entering hole valve body and liquid outlet valve body is equipped with sealing surface, and flashboard is between two sealing surfaces; The liquid outlet valve body is provided with the deslagging runner that is positioned at the flashboard below, and this runner communicates with the inner chamber of liquid outlet valve body.
During use; Impurity is discharged through deslagging runner, liquid outlet body cavity under the effect of pressure automatically, can avoid the impurity front to wash away sealing surface, when gate valve is closed; Impurity also is difficult for attached on the sealing surface; Avoid the flashboard channel jam, make flashboard to close and put in place, can guarantee the sealability of gate valve for a long time;
As the further improvement of the utility model, the cross section of said valve gap is circular; Than square cross section, its intensity is higher, long service life.
In sum, the utility model can avoid the impurity front to wash away sealing surface, and guarantees the sealability of gate valve, long service life for a long time.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
By shown in Figure 1; This wear-resisting deslagging does not have the obstruction gate valve, comprises valve body 1, valve gap 2, valve rod 3, handwheel 4, flashboard 5 and material filling type seal arrangement 6, and said valve body 1 is a fabricated structure; It comprises through the liquid entering hole valve body 1a of Bolt Connection and liquid outlet valve body 1b; The adjacent face of liquid entering hole valve body 1a and liquid outlet valve body 1b is equipped with sealing surface, and flashboard 5 is between two sealing surfaces, and liquid outlet valve body 1b is provided with the deslagging runner 7 that is positioned at the flashboard below; This runner 7 communicates with the inner chamber of liquid outlet valve body 1b, and the cross section of said valve gap 2 is circular;
During use; Impurity is discharged through deslagging runner 7, liquid outlet body cavity under the effect of pressure automatically, can avoid the impurity front to wash away sealing surface, when gate valve is closed; Impurity also is difficult for attached on the sealing surface; Avoid the flashboard channel jam, make flashboard 5 to close and put in place, can guarantee the sealability of gate valve for a long time.
Claims (2)
