Abstract
The utility model relates to a shearing flow valve, which is characterized in that a T-shaped groove is formed on a wedge disc; the wedge disc is connected with a valve rod through the T-shaped groove; a valve cap is arranged on the valve rod; and an upper packing opening is formed on the valve cap; and a packing fixing part is arranged in the upper packing opening. When the shearing flow valve is used, the valve rod is inserted into the T-shaped groove of the wedge disc, so as to effectively reduce space, improve the width and thickness of the wedge disc, enable the valve body structure to be greatly reduced compared with the traditional valve body, save materials and achieve a simpler structure, and convenient operation and use. At the same time, the combination of a hold-down nut and a copper bushing serves as the packing fixing part, so that the installation is facilitated, the material is saved, and the upper sealing performance of the valve is enhanced through a sealing ring added to the top part of a joint of the valve rod.
Description
Technical field:
The utility model relates to the technical field of mechanical valve, specifically a kind of flow cutting valve.
Background technique:
Present existing flow cutting valve, gate valve by valve rod connecting band thread bush, the size of flashboard will consider that not only the thickness of valve rod also must consider the surplus of connecting head, and the size of flashboard connecting head, determine the thickness of flashboard, caused the flashboard volume big, waste of material, the thickness of flashboard has then determined the middle-grade size of valve body, just makes whole valve mechanism complexity, heavier, the waste material of weight.The fixing of filler fixed with earrings and swing bolt simultaneously, in use operates more complicated, brings greater inconvenience.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved flow cutting valve,, it can overcome in the prior art, and the flashboard volume is big, waste of material, valve mechanism complexity, the heavier some shortcomings of weight.
To achieve these goals, the technical solution of the utility model is: flow cutting valve, it mainly comprises valve body, with the flashboard and the valve rod that are located in the valve body, it is characterized in that: flashboard is provided with T type groove, and flashboard links to each other by T type groove with valve rod, and valve rod is provided with valve gap, valve gap is provided with feeding port, and last feeding port is provided with the filler fixed block.
Valve rod of the present utility model inserts in the T type groove of flashboard during use, can reduce the space effectively, make the scantling of flashboard be improved, the traditional relatively valve body of valve body structure is reduced greatly, and structure is also more simple when saving material, easy-to-operat and use, select for use gland nut and copper lining to cooperate simultaneously as the filler fixed block, not only make things convenient for installation but also saved material, and increase seal ring one, make the last sealability of valve improve by connecting head top at valve rod.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Fig. 2 is the side view of Fig. 1
Fig. 3 is a flashboard structure schematic representation of the present utility model
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises valve body 7 and is located at flashboard 6 and valve rod 9 in the valve body, and it is characterized in that: flashboard is provided with T type groove, and flashboard links to each other by T type groove with valve rod, and valve rod is provided with valve gap 1, and valve gap is provided with feeding port, and last feeding port is provided with the filler fixed block.The filler fixed block is formed by connecting by copper lining and the gland nut 3 that cooperates with copper lining 2.Valve rod is formed by connecting by threaded stem, polished rod and connecting head three parts, and the connecting head of valve rod is provided with seal ring.Seal ring adopts the O RunddichtringO.The diameter of valve rod is greater than the width of T type groove, and flashboard is made by iron core, outer wrapping rubber.
In force, the slightly larger in diameter of valve rod is in the width of T type groove, valve rod inserts T type groove, driving flashboard opens and closes, valve rod is divided into threaded stem, polished rod and connecting head three parts, the top of valve rod connecting head is provided with an O type circle, goes up sealing together to increase, and forms disposable sealing with the back seal of valve gap., valve gap is provided with feeding port, and last feeding port is provided with the filler fixed block.The filler fixed block is formed by connecting by copper lining and the gland nut 3 that cooperates with copper lining 2.One end of valve rod is provided with Stem Mut 4 and handwheel 5, because Stem Mut 4 and handwheel 5 all are prior arts, has just repeated no more its working principle and structure here.
