Abstract
The utility model relates to a DC globe valve with the valve sealing face replaceable; the globe valve is formed from an upper part and a lower part, both of which are provided with a flange; the upper valve and the valve cover is connected together and form the valve cover body, the lower valve and the middle flange are connected together and form the lower valve body; rabbets are opened on the surface where the lower valve body and the valve cover body are jointed; the rabbet is provided with a valve seat with sealing face; a gasket is positioned between the valve seat and the lower valve body and the valve cover body. The center of the joint connecting the lower valve body and the valve cover body excurses towards on the end of the flange of the lower valve body; the outer end of the lower valve body and the valve cover body is respectively provided with a reinforcing rib, and the reinforcing ribs are fixed and connected by a removable mount. Only the valve seat is needed to be replaced in case that the sealing surface of the globe valve is damages and if the globe valve needs to be used in different medium. Therefore, the globe valve is reusable, which reduces consumption, greatly saves cost and expands the scope of application of the globe valve.
Description
(1) technical field:
The utility model relates to a kind of valve, particularly a kind of Oblique Stop Valve with interchangeable valve sealing face after the valve fractionation.
(2) background technique:
Existing direct current type by sealing pair normally by flap sealing surface and built-up welding on the valve body or the sealing surface that is pressed on the valve body form.Because sealing surface is on valve body, after stop valve uses, because of being subjected to washing away of flowing medium, and under the extruding of grit when valve closing influences in the medium, make stop valve close inefficacy.At this moment stop valve need be changed whole valve body or whole stop valve usually.Again when the Chemical composition of flowing medium changes, when being not suitable for this medium, the sealing material of built-up welding on valve body also need change whole valve body or whole deck valve door usually.
(3) model utility content:
The utility model will provide a kind of need only change the stop valve sealing surface, need not change valve body and just can keep in repair because of valve body sealing surface damages the leakage that causes, and the sealing surface of changing different materials just is adapted at the stop valve that uses in the different chemical composition medium.
The stop valve of replaceable sealing surface, comprise valve body, valve gap, flap, valve rod, described valve body be divided into respectively with a flange up and down two partly, upper body and valve gap are fixed with one and form the valve gap body, lower body and middle flange are fixed with one and form the valve lower body, on the interface that valve lower body and valve gap body dock each other, all offer seam, be provided with a valve seat that has sealing surface in the seam.
Be provided with seal ring between valve seat and valve lower body and the valve gap body.
Flange one end skew on the middle mind-set valve lower body of valve lower body and valve gap body docking port.
The external end of valve lower body and valve gap is respectively equipped with stiffening rib, is connected by detachable fixed block between the stiffening rib.
Because this stop valve is taked valve body is resolved into three partly, when the sealing surface of stop valve rapid wear damages, the damage valve seat need only be replaced with qualified valve seat and get final product, make the repeated use of this stop valve become possibility, reduced consumption, greatly provide cost savings.When stop valve uses in different medium, also only need corresponding valve seat of replacing and seal face materials to get final product, thereby enlarged a kind of using scope of stop valve.
(4) description of drawings:
Fig. 1 is the structural representation of a kind of mode of execution of the utility model;
Fig. 2 is the A-A direction sectional view of mode of execution shown in Figure 1.
(5) embodiment:
The stop valve of this replaceable sealing surface, identical with traditional stop valve, also comprise valve body, valve gap, flap, valve rod, but described valve body be divided into respectively with a flange up and down two partly, upper body and valve gap are fixed with one and form valve gap body 1, lower body and middle flange are fixed with one and form valve lower body 2, on the interface that valve lower body 2 and valve gap body 1 body dock each other, all offer seam 3, be provided with a valve seat 4 that has sealing surface 8 in the seam 3, be provided with seal ring 5 between valve seat 4 and valve lower body 2 and the valve gap body 1, be two end flange of assurance valve and the installation of pipeline, reduce the flow resistance of flowing medium to greatest extent, the utility model with the closing center of valve to valve lower body 2 side shiftings, be valve lower body 2 with the middle mind-set valve lower body 2 of valve gap body 1 docking port on the skew of flange one end, for guaranteeing the bulk strength of the utility model valve, between valve lower body 2 and valve gap body 1, increase stiffening rib 6, be connected as being fastenedly connected with hex screw and hexagon nut by detachable fixed block 7 between the stiffening rib 6, this eliminates simultaneously to stiffening rib, and 2 bodies and valve gap body 1 relatively rotate on the valve rod shaft axis under the valve.
The utility model valve, also keeping the keying custom of conventional valves perpendicular to conduit axis, this keying custom, can eliminate relatively moving of two end flange, improve the bulk strength of this valve, because valve seat 4 is to be embedded in valve gap body 1 and valve lower body 2 seams 3, when valve sealing face 8 damages, need only change valve seat 4 and flap 9 gets final product, when the valve of demand different materials sealing surface, equally also need only change valve seat 4 and flap 9 gets final product, thereby improve the maintenance of valve and enlarged the using scope of valve.
