Abstract

A ceramic hard-seal triple eccentric telescopic valve consists of a valve body (1), a valve plate (2) and a telescopic tube (6), and is characterized in that a valve body ceramic hard sealing ring (3) is arranged on the valve body (1); a valve plate ceramic hard sealing ring (4) is arranged on the valve plate (2); the body ceramic hard sealing ring (3) is embedded in the valve seat (5) which is fixed on the valve body (1) through bolts; the plate ceramic hard sealing ring (4) is fixed on the valve plate through a pressure plate; a telescopic rubber sealing ring (7) is arranged on the telescopic tube (6) and is fixed on the telescopic tube (6) through the pressure plate; the part of the valve contacted with a medium and a sealing surface are subjected to process ceramic treatment and produced into the ceramic hard-seal valve; and the long-time stable work of the valve can be ensured under the harsh industrial and mining condition, and the defects that the present valve has short service life and cannot resist wear can be overcome, therefore the valve achieves the effects of wear resistance, corrosion resistance, fouling resistance, high temperature resistance and long service life.

Description

The hard sealing of a kind of pottery three eccentric extension valves

Technical field

The utility model relates to a kind of valve, the hard sealing of particularly a kind of pottery three eccentric extension valves.

Background technique

Hard sealed valve in the past, the sealing pair that adopts stainless steel or alloy to make, in use, owing to the burn into of medium such as washes away at reason, damage easily at short notice and cause leakage, conventional valve causes valve can't install or the method hurdle is broken in use because piping erection error and variation of temperature can cause the pipeline axial displacement, brings certain influence for the normal operation of production.

Summary of the invention

The purpose of this utility model be to overcome above-mentioned deficiency of the prior art exactly and a kind of corrosion resistance be provided, prevent to reveal, the hard sealing of non-damageable pottery three eccentric valves.

For achieving the above object, the utility model is to adopt following scheme to be achieved in that the hard sealing of a kind of pottery three eccentric extension valves, it is made up of valve body (1), valve plate (2), telescopic pipe (6), its spy is: valve body (1) is provided with the hard seal ring (3) of valve body pottery, valve plate (2) is provided with the hard seal ring (4) of valve plate 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; Telescopic pipe (6) is provided with telescopic rubber seal ring (7), and telescopic rubber seal ring (7) is fixed on the telescopic pipe (6) 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, telescopic rubber seal ring are fixed by platen, can change at any time under damage situations.

3, this valve can compensate automatically because the piping displacement that temperature variation causes can be adjusted structure length according to the mounting point in installation process.

4, adjustable platen structure is adopted in flexible sealing, in use can obtain rational seal pressure by adjusting the platen bolt, guarantees to work long hours not have and reveals.

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, telescopic rubber seal ring are fixed by platen, can change at any time under damage situations, obtain new sealing.Adjustable platen structure is adopted in flexible sealing, in use can obtain rational seal pressure by adjusting the platen bolt, guarantees to work long hours not have and reveals.

Claims

1. a pottery seals three eccentric extension valves firmly, it is made up of valve body (1), valve plate (2), telescopic pipe (6), its spy is: valve body (1) is provided with the hard seal ring (3) of valve body pottery, valve plate (2) is provided with the hard seal ring (4) of valve plate 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; Telescopic pipe (6) is provided with telescopic rubber seal ring (7), and telescopic rubber seal ring (7) is fixed on the telescopic pipe (6) by platen.
