Abstract
The utility model discloses a novel plunger control valve, and relates to the field of processing and manufacture for fluid valves. The novel plunger control valve is characterized in that a valve body of the novel plunger control valve is integrally divided into an upper portion and a lower portion and is fixed via a bolt, space between an inlet and an outlet which are arranged at two ends of the valve body is of a straight-through type, a vertical cylindrical cavity is arranged in the valve body, a valve bonnet is arranged at the upper end of the cylindrical cavity, a sealing ring is embedded on side walls of the cylindrical cavity, a hand wheel is fixed to the upper end of a valve stem, the valve stem penetrates through the upper end of the valve bonnet to be connected with a plunger nut, a cap nut is arranged on the inner side of the valve bonnet, the plunger nut is fixed to the upper end of a plunger, the plunger is arranged in the cylindrical cavity and is positioned between the inlet and the outlet of the valve body, and a gasket is sleeved on the plunger nut. As the novel plunger control valve is of a straight-through type, the novel plunger control valve is low in fluid resistance and friction force and is not easy to block, the service life of the novel plunger control valve is greatly prolonged, the novel plunger control valve is convenient to manufacture and maintain, good in sealing performance and short in working stroke and starting time, and the flow rate can be effectively controlled according to actual requirements.
Description
Technical field:
The utility model relates to a kind of manufacturing field of Fluid valve, is specifically related to a kind of improvement of Novel plunger control valve.
Background technique:
Common plunger control valve in the market; because what its inner chamber adopted mostly is bent chamber, fluid resistance is larger, and required strength is larger when closing; especially be not suitable for being with particle; viscosity is larger, the liquid that easily condenses, and can not carry out Flow-rate adjustment; usually can because wear out leakage accident comparatively fast occur in the using process for a long time; reduced utilization ratio, reduced greatly the Security when using, and maintenance and cost of upkeep are higher.
The model utility content:
The purpose of this utility model provides a kind of Novel plunger control valve, and it adopts the straight-through type design, so its fluid resistance is less, frictional force is also less, and difficult the obstruction increased working life greatly, and it is also comparatively convenient to make and keep in repair.
In order to solve the existing problem of background technique, the utility model by the following technical solutions: it comprises valve body 1, circular cylindrical cavity 2, seal ring 3, plunger 4, pad 5, post nut 6, valve gap 7, valve rod 8, cap nut 9, handwheel 10 and bolt 11; Valve body 1 integral body is divided into up and down two parts, and fixing by bolt 11, its two ends are straight-through type between importing and exporting, be provided with a up and down vertical circular cylindrical cavity 2 in this valve body 1, the upper end of this circular cylindrical cavity 2 is provided with valve gap 7, be embedded with a circle seal ring 3 on its sidewall, handwheel 10 is fixed on the upper end of valve rod 8, valve rod 8 pass valve gap 7 the upper end, be connected with post nut 6, the inboard of valve gap 7 is provided with cap nut 9, post nut 6 is fixed on the upper end of plunger 4, plunger 4 is arranged in the circular cylindrical cavity 2, and between valve body 1 import and outlet, pad 5 is enclosed within on the post nut 6.
Stagger up and down between the import medial axis of described valve body 1 and the outlet medial axis.
Be interference fit between described seal ring 3 and the plunger 4.
The utlity model has following beneficial effect: owing to be straight-through type, fluid resistance is less, frictional force is also less, so be difficult for stopping up, has increased greatly working life, it is also comparatively convenient to make and keep in repair, and sealability is better, and working stroke is little, and starting time is short, can be according to actual needs, the size of effective coutroi velocity.
Description of drawings:
Fig. 1 is the structural representation of the first embodiment of the present utility model;
Fig. 2 is the structural representation of the second embodiment of the present utility model.
Embodiment:
The first embodiment of the present utility model is by the following technical solutions as shown in Figure 1: it comprises valve body 1, circular cylindrical cavity 2, seal ring 3, plunger 4, pad 5, post nut 6, valve gap 7, valve rod 8, cap nut 9, handwheel 10 and bolt 11; Valve body 1 integral body is divided into up and down two parts, and fixing by bolt 11, its two ends are straight-through type between importing and exporting, be provided with a up and down vertical circular cylindrical cavity 2 in this valve body 1, the upper end of this circular cylindrical cavity 2 is provided with valve gap 7, be embedded with a circle seal ring 3 on its sidewall, be interference fit between sealing ring 3 and the plunger 4, handwheel 10 is fixed on the upper end of valve rod 8, valve rod 8 pass valve gap 7 the upper end, be connected with post nut 6, the inboard of valve gap 7 is provided with cap nut 9, and post nut 6 is fixed on the upper end of plunger 4, and plunger 4 is arranged in the circular cylindrical cavity 2, and between valve body 1 import and outlet, pad 5 is enclosed within on the post nut 6.
Stagger up and down between the import medial axis of described valve body 1 and the medial axis of outlet, preferred import is positioned at the below of outlet, and the lower wall of its middle outlet ends to extending to plunger 4 to the importer, and extension is connected with the lower wall of import vertically downward.
Fig. 2 shows the second embodiment of the present utility model, a cavity is extended at the middle part of valve body 1 downwards, the diameter of this cavity is identical with the diameter of circular cylindrical cavity 2, when being in closed condition, plunger 4 inserts in this cavity, and other constituent elements is identical with the first embodiment shown in Fig. 1 with annexation.
This embodiment mode has following beneficial effect: owing to be straight-through type, fluid resistance is less, frictional force is also less, so be difficult for stopping up, has increased greatly working life, it is also comparatively convenient to make and keep in repair, and sealability is better, and working stroke is little, and starting time is short, can be according to actual needs, the size of effective coutroi velocity.
