Abstract
The utility model relates to a ceramic hard sealing double-eccentric dome valve which is characterized in that a valve body (1) is provided with a valve body ceramic hard sealing ring (3), a valve plate (2) is provided with a ceramic hard sealing ring (4), the valve body ceramic hard sealing ring (3) is inlaid on a valve seat (5) which is fixed on the valve body (1) through a bolt, and the valve plate ceramic hard sealing ring (4) is fixed on the valve plate through a pressure plate. A part of the valve contacting with a medium and a front cover are processed through technological ceramic coating to be manufactured to the ceramic hard sealing valve, so as to ensure the valve to stably work under harsh industrial and mining conditions for a long time, solve the disadvantages of short service life and no wear resistance of the existing valve, and achieve the effects of wear resistance, corrosion and scaling prevention, high temperature resistance and long service life; and the valve plate and the valve body ceramic hard sealing ring are fixed through the pressure plate, and can be replaced at any time under the condition of being damaged.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of ceramic hard sealing double eccentric dome valve.
Background technique
Two eccentric circle overhead-valve doors in the past, the sealing pair that adopts stainless steel or alloy to make in use, owing to reasons such as the burn into of medium wash away, damages easily at short notice and causes leakage, gives to produce normal operation and bring certain influence.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art exactly and a kind of corrosion resistance, non-damageable ceramic hard sealing double eccentric dome valve is provided.
For achieving the above object, the utility model is to adopt following scheme to be achieved in that a kind of ceramic hard sealing double eccentric dome valve, its spy is: valve body (1) is provided with the hard seal ring (3) of valve body pottery, valve plate (2) has been provided with the hard seal ring (4) of pottery, the hard seal ring (3) of valve body pottery is embedded on the valve seat (5), valve seat (5) is by being bolted on the valve body (1), and the hard seal ring (4) of valve plate pottery is fixed on the valve plate by platen.
The utility model advantage:
1, be that occurring in nature hardness is only second to adamantine characteristics according to pottery, with valve contact medium position and front cover adopting process ceramic treatment, make the hard sealed valve of pottery, can guarantee long-time stable work under harsh industrial and mineral condition, solve in the past the short not anti abrasive drawback of life of valve, thereby reached wear-resisting, corrosion protection, good antiscale property, high temperature resistant, effect that the life-span is long.
2, valve plate, the hard seal ring of valve body pottery are fixed by platen, can change at any time under damage situations.
3, this valve adopts two eccentric structures, and valve plate is the semi major axis dome structure, can effectively reduce the wearing and tearing of the hard seal ring of pottery in opening-closing process, and after the unlatching, the dome valve plate enters valve pocket, avoids medium because of washing away valve plate, causes the wearing and tearing of ceramic seal circle.
Description of drawings
Fig. 1 is the utility model structural representation
Embodiment
According to shown in Figure 1,, wear-resisting, corrosion protection, good antiscale property, high temperature resistant, effect that the life-span is grown have been reached in the course of the work because this valve body and valve plate contact medium position and front cover adopting process ceramic treatment; Valve plate, the hard seal ring of valve body pottery are fixed by platen, can change at any time under damage situations, obtain new sealing.
Claims (1)
