Abstract
The utility model discloses a material conveying valve with a protective sleeve installed on a valve seat. The material conveying valve with the protective sleeve installed on the valve seat solves the problems that due to the fact that an existing material conveying valve is impacted by media and foreign matters in a repeated mode during use, a rigid and fragile ceramic valve seat is broken, seal can not be achieved after the valve is closed, inner leakage and outer leakage of materials occur, and pollution is caused. Inside a shell body, the ceramic valve seat is matched with a valve plate in a sealing mode, the ceramic valve seat is matched with an annular groove of the protective sleeve, the ceramic valve seat is located inside the annular groove of the protective sleeve, and the protective sleeve is connected with the shell body.
Description
Technical field:
The utility model is relevant with the valve in ash transfer storehouse pump, pipeline and the grey storehouse in thermal power plant, and is especially relevant with the mass transport valve.
Background technique:
Existing mass transport valve, ceramic valve seat is bonded on the housing, ageing of binders after use a period of time, ceramic valve seat is subjected to displacement or breaks away from, and working life is short.In use be subjected to the bump repeatedly of medium and foreign matter; make hard crisp ceramic valve seat break; can not seal behind the valve closing; material forms the high speed narrow slit from rent and washes away; destroy shell flange, make and carry pulverized fuel ash to leak in producing and leak outside, cause environmental pollution; run counter to the protection environment of country, eliminate the requirement that debirs cause environmental pollution substantially.Ceramic valve seat separates with trim ring, assembling and dismounting inconvenience.
The model utility content:
The purpose of this utility model provides a kind of simple in structure, easy installation and removal, the ceramic valve seat destruction that is not hit, the mass transport valve of the valve seat band protecting jacket of long service life.
The utility model is achieved in that
Ceramic valve seat and valve plate are sealed and matched, and ceramic valve seat cooperates with the circular groove of protecting jacket, and ceramic valve seat is positioned at the circular groove of protecting jacket, and protecting jacket is connected with housing.
The cylindrical wall of the circular groove of protecting jacket is terminal to be cooperated with trim ring, has step to cooperate with the interior circle of trim ring on the outer cylinder of ceramic valve seat, and some first screws are connected trim ring and protecting jacket.
Described housing is made up of valve body and valve gap, and protecting jacket is connected on the valve gap by second screw, has rotating shaft to be connected with pivoted arm on the valve gap, and pivoted arm is connected with valve plate.
In the peripheral groove of described housing valve plate is arranged; there is first and second ceramic valve seat to be sealed and matched with the left and right sides of valve plate respectively in the peripheral groove; first and second ceramic valve seat is connected with first and second protecting jacket respectively; between first and second protecting jacket and peripheral groove are axial the O RunddichtringO is arranged, the upper end of valve plate is connected with valve rod.
Protecting jacket and trim ring are formed from steel, and the hardness of protecting jacket and trim ring is greater than the hardness of housing, less than the hardness of ceramic valve seat.
The utility model has following advantage:
(1) ceramic valve seat is protected with the metal seat valve cover; under the collision of medium and foreign matter, can not be damaged, thereby put forward working life and the sealability of having done valve; do not leak in use can not producing and leak outside, can not cause pulverized fuel ash to the pollution of atmosphere environment.
(2) valve seat of band protecting jacket is integrated package, and is simple in structure, and it is convenient to make, mount and dismount.
(3) the long-term use of ceramic valve seat is not shifted or breaks away from, and sealing is reliable, uses not have 3 years more and damages, and receives praises from customers.The ceramic valve seat of existing mass transport valve uses be damaged half a year.
Description of drawings:
Fig. 1 is one of structural drawing of the present utility model.
Fig. 2 is two of structural drawing of the present utility model.
Embodiment:
Embodiment 1:
