Abstract
The utility model relates to the technical field of gate valves, in particular to a novel non-rising stem gate valve. According to the novel non-rising stem gate valve, leakage points are reduced, and the sealing effect is better ensured. The novel non-rising stem gate valve comprises a valve body, a valve rod, a valve cover, a bearing and a sheet gasket, wherein the valve body and the valve cover are mounted together; a handwheel and a valve plate are mounted at the top end and the bottom end of the valve rod respectively; the bearing is mounted between the valve body and the valve cover, and is fixed on the valve cover through a bearing gland; the bottom end of the valve rod penetrates through the bearing and extends into the valve body; and the sheet gasket is fixed between the valve body and the valve cover.
Description
Technical field
The utility model relates to the gate valve technical field, particularly relates to a kind of novel inside screw non-rising stem type gate valve.
Background technique
As everyone knows, inside screw non-rising stem type gate valve is and is the swingle gate valve; Be a kind of of valve, existing inside screw non-rising stem type gate valve comprises valve body, valve rod and valve gap, and valve body and valve gap are installed together; The top of valve rod is equipped with handwheel, and its bottom stretches to downwards in the valve body from the top of valve gap, in the bottom of valve rod valve plate is installed; And locate valve rod through the sealing locating support that is installed between valve body and the valve gap, stem shaft is provided with positioning groove, with two divided rings fixedly valve rod on valve gap; The sealing locating support cooperates the valve gap location; Valve rod can only can not move up and down with rotatablely moving behind the location, and its valve gap is that bolt is connected with the locating support Placement; Bolt can produce the scholar change when the valve working temperature rises, and the pressure in the valve pocket is easy to leak.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of leakage point that reduced, and has better guaranteed the novel inside screw non-rising stem type gate valve of its sealing effect.
The novel inside screw non-rising stem type gate valve of the utility model comprises valve body, valve rod and valve gap, and valve body and valve gap are installed together; The top of valve rod and bottom are separately installed with handwheel and valve plate; Also comprise bearing and gasket seal, said Bearing Installation and is fixed on the valve gap through bearing gland in valve gap; The bottom of said valve rod is passed bearing and is stretched in the valve body, and said gasket seal is fixed between valve body and the valve gap.
The novel inside screw non-rising stem type gate valve of the utility model, the inwall of said valve gap is provided with filler, and said filler is installed on the said valve gap through Gland, and said valve rod contacts with said filler, and said filler is graphite packing.
Compared with prior art the beneficial effect of the utility model is: be provided with bearing and gasket seal; Bearing Installation is between valve body and valve gap; And bearing is fixed on the valve gap through bearing gland, and the bottom of valve rod is passed bearing and stretched in the valve body, and gasket seal is fixed between valve body and the valve gap; Like this, locate valve rod through bearing, it has saved the sealing locating support; Reduced leakage point, the valve rod axial pressure was done entirely and is used in valve pocket inside when pressure-bearing was closed, the global reliability of sealing when having guaranteed to close; Machining is more convenient with installation, and Economy is higher, and valve rod can directly be rotated motion; The coordination performance of bearing is better, and also can strengthen sealing effect through gasket seal.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1, the novel inside screw non-rising stem type gate valve of the utility model comprises valve body 1, valve rod 2 and valve gap 3; Valve body 1 is installed together with valve gap 3, and the top of valve rod 2 and bottom are separately installed with handwheel 4 and valve plate 5, also comprises bearing 6 and gasket seal 8; Bearing 6 is installed between valve body 1 and the valve gap 3; And bearing 6 is fixed on the valve gap 3 through bearing gland 7, and the bottom of valve rod 2 is passed bearing 6 and stretched in the valve body 1, and gasket seal 8 is fixed between valve body 1 and the valve gap 3; Like this, locate valve rod through bearing, it has saved the sealing locating support; Reduced leakage point, the valve rod axial pressure was done entirely and is used in valve pocket inside when pressure-bearing was closed, the global reliability of sealing when having guaranteed to close; Machining is more convenient with installation, and Economy is higher, and valve rod can directly move up and down; The coordination performance of bearing is better, and also can strengthen sealing effect through gasket seal.
The novel inside screw non-rising stem type gate valve of the utility model, the inwall of valve gap 3 is provided with filler 9, and filler 9 is installed on the valve gap 3 through Gland 10, and valve rod 2 contacts with filler 9, and filler 9 is graphite packing.And Stem Mut is an Austenitic Stainless Steel, and like this, the serviceability temperature of this valve can reach 350 degrees centigrade, and applicable working condition is wider, safeguards that use is more convenient.
The novel inside screw non-rising stem type gate valve of the utility model adopts valve rod to install from the bottom up, and the integrated valve gap can prevent effectively that valve rod from flying out.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
