Abstract
A baghouse valve construction including an annular valve seat member and valve member adapted to cooperate with the same in assuming open and closed relative positions. The valve seat having a pair of annular, radially spaced resilient seal members and at least one generally rigid seal member. Retainers secure the resilient seal members in relative spaced position. The valve seat may have two generally rigid seal members. One generally rigid seal member may be adjustable relative to the position of the valve element. In a preferred form, the resilient seal members have a core composed of a first material and a tubular outer member composed of a second material.
Claims15
A baghouse valve construction comprising an annular valve seat member,
- a valve element adapted to assume a closed position in intimate engagement with said valve seat member and an open position spaced from said valve seat member,
- said valve seat having a pair of annular, radially spaced resilient seal members,
- said valve seat member having at least one generally rigid seal member;
- and
- retainer means for securing said resilient seal members in said relative radially spaced position.
A baghouse valve construction comprising
- an annular valve seat member having a base portion,
- a valve element adapted to assume a closed position in intimate engagement with said valve seat member and an open position spaced from said valve seat member,
- said valve seat having a pair of annular, radially spaced resilient seal members,
- retainer means for securing said resilient seal members in said relative radially spaced position, said retainer means having a plurality of clip members and at least a portion of said retainer means being interposed between said resilient seal members, said retainer means securing said resilient seal members to said base portion, and
- said valve seat member having at least one generally rigid seal member.
A baghouse valve construction comprising
- an annular valve seat member,
- a valve element adapted to assume a closed position in intimate engagement with said valve seat member and an open position spaced from said valve seat member,
- said valve seat having a pair of annular, radially spaced resilient seal members,
- said valve seat member having a pair of generally rigid seal members,
- a first said rigid seal member disposed generally radially inwardly of the innermost of said resilient seal members and being adjustable with respect to said resilient seal members, and
- a second rigid seal member disposed generally radially outwardly of the outermost of said resilient seal members.
