Abstract
The utility model discloses a material conveying valve with an L-shaped protective sleeve installed on a valve seat. The material conveying valve with the L-shaped protective sleeve installed on the valve seat solves the problems that an existing material conveying valve is inconvenient to assemble and disassemble, a ceramic valve seat is damaged due to impact, and the service life is short. Inside a shell body, the ceramic valve seat is matched with a valve plate in a sealing mode, the cross section of the ceramic valve seat and the cross section of the protective sleeve are in the L shape, the ceramic valve seat is matched with an annular groove of the protective sleeve, and the ceramic valve seat is located inside the L-shaped protective cover and 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.
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 L type protecting jacket of long service life.
The utility model is achieved in that
Have ceramic valve seat and valve plate to be sealed and matched in the housing, the cross section of ceramic valve seat and protecting jacket is L shaped, and ceramic valve seat cooperates with the circular groove of protecting jacket, and ceramic valve seat is positioned at L type protecting jacket, is connected with housing.
Step on the outer cylinder of ceramic valve seat cooperates with the interior circle of trim ring, and screw is connected trim ring, ceramic valve seat and protecting jacket and housing.
Described housing is made up of valve body and valve gap, and trim ring is connected on the valve gap by screw, has rotating shaft to be connected with pivoted arm on the valve gap, and pivoted arm is connected with valve plate.
Described 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 L type protecting jacket 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.
Embodiment:
The millstone type mass transport valve of the utility model valve seat band L type protecting jacket; ceramic valve seat 8 is L shaped with the cross section of metal protection protector 6; ceramic valve seat cooperates with the circular groove of metal protection protector; ceramic valve seat is positioned at L type protecting jacket; valve body 1 is connected with valve gap 4 usefulness bolts; one end of the lower end of rotating shaft 5 and pivoted arm 2 is connected; the other end of pivoted arm 2 is connected with valve plate 3; ceramic valve seat 8 on valve plate 3 and the valve gap 4 is sealed and matched, and ceramic valve seat 8 is connected the back and is connected on the valve gap 4 by screw 7 with metal trim ring 9 with metal protection protector 6.
