Embodiment
In order to make those skilled in the art person better understand the utility model scheme,, the technological scheme among the utility model embodiment is carried out clear, complete description below in conjunction with the accompanying drawing among the utility model embodiment.
As shown in Figure 1, a kind of angle gate valve, comprise valve body 1, the bonnet 3 that is connected with valve body 1 and the valve rod 2 that places valve body 1, be formed with a passage 11 for the medium circulation in the valve body 1, valve rod 2 is provided with perpendicular to the media flow direction, and the lower end of valve rod 2 flashboard 4 that is used to open and close passage 11 that is threaded is during rotation valve rod 2, flashboard 4 can move up or down, to reach the effect of opening and closing passage; The upper end of valve rod 2 is passed bonnet 3 and is connected with one handle 25, and the entrance point of described valve body 1 is a bending extension part 13, and this bending extension part is communicated with passage 11.One end and the valve body 1 of bending extension part 13 are structure as a whole, and the other end is connected with pipeline.
When needing to use valve in the pipeline of turning, only need two ends with this valve directly be connected and get final product with pipeline, need not to set up elbow and connecting tube, reduced the generation of leakage accident, saved material, and easy for installation, quick.If desired, in other embodiments, the entrance point and the outlet end of valve body 1 all can be made as the bending structure, perhaps only outlet end be made as the bending structure.
And in the present embodiment, valve body is a metal material, existing pipeline is generally joint for plastic tube, being connected between metal valve and the plastic piping for convenience, optionally, the entrance point of described valve body (being bending extension part 13) is connected a joint for plastic tube 5 by a locking nut 7 respectively with outlet end 14, joint for plastic tube 5 is provided with a seal ring 8 with the junction of valve body, realize that joint for plastic tube is connected with reliable sealing between the valve body, during connecting pipeline, joint for plastic tube is connected with the pipeline hot melt gets final product, practical very convenient, good seal performance; And cooperate with valve body by a screw-nut, joint for plastic tube, when the valve damage maybe needs to change, only need back out locking nut 7, new valve can be installed, need not to cut off being connected between joint for plastic tube and the pipeline body, easy for installation, connect soon, and improved working efficiency.Moreover in other embodiments, this valve body can be plastic material, then adopt said structure after, also can carry out demolition and replacement fast.
Further, for the sealing between joint for plastic tube 5 and the valve body is improved, as shown in the figure, the contact segment with locking nut 7 on the outer wall of described joint for plastic tube 5 is provided with an annular convex shoulder 51, and the inboard of locking nut 7 is provided with the retaining that cooperates with annular convex shoulder 51 along 71; Described seal ring 8 is circular cone shape, and valve body 1 inwall is provided with the conical surface 61 that matches with the circular cone table top with the seal ring contact segment, conflicts with annular convex shoulder 51 end faces in 8 mouthfuls of edges of seal ring; Concrete, described annular convex shoulder 51 is positioned at the end of joint for plastic tube 5, and annular convex shoulder 51 front ends are provided with an annular boss 9, and seal ring 8 is sheathed on this annular boss 9.
In order to save installing space and versatility, optionally, described bending extension part 13 is an elbow bend, the one end is connected with valve body 1, the other end is provided with perpendicular to the horizontal plane direction, and this structure is a vertical structure, also can be horizontal type structure as required, be that its other end is parallel to the setting of horizontal plane direction, perhaps become other angles all can with horizontal plane.
