Abstract
The utility model relates to a loose joint valve; under the utilization of the utility model, a pipe which needs installing does not need putting into the operation of threading. The input end of the utility model is composed of a plug screw, a sealing ring and an adapter sleeve, and the output end of the utility model is composed of screw caps, a sealing ring and an adapter sleeve. When the utility model needs installing, a pipe is directly inserted in a valve, and then, the plug screw and the screw caps are respectively screwed. Sealing pressure is greater than 2.4MPa, and receiving pull force in an axial direction is greater than 1000 newton.
Description
The utility model relates to a kind of valve, and it is applicable to inside nominal diameter Dg15-50mm, and nominal pressure is less than or equal to 0.8MPa, and medium temperature is no more than 100 ℃ general pipeline such as transporting water, air and coal gas.
The valve that is adopted on the at present general pipeline is to belong to the wire connection link that pipe when installing needs mantle fiber, and not only installation efficiency is low, and valve breaks easily when installing.For this reason, pipe has been applied for multinomial patent without the Connecting valve that is referred to as of mantle fiber during a kind of the installation.But these patents are not applied.One of these patent shortcomings are darker in the pipe insertion valve body, are difficult to form loose joint, also need to install in addition union in pipeline.Two of shortcoming is poor performance, only relies on the crush seal circle to finish sealing and fastening effect to pipe, and it bears pressure is 0.9-1.2MPa, axially bears pulling force and has only 3000 newton, poor reliability.
The purpose of this utility model is to overcome the deficiency of prior art, proposes direct insertion loose joint valve for this reason.
Design of the present utility model realizes by structure shown in the drawings.The input end of valve body is to belong to plug screw type structure.Seal ring is arranged in valve body, and the outside is furnished with an adapter sleeve, and the conical surface of adapter sleeve matches with the plug screw conical surface of its outside.Because adopt plug screw type structure, the valve body input end is a female thread, polygon just can be made in its outside, such as octagon.When the both sides pipe was installed, this octagon just can play the fixedly effect of spanner.The output terminal of valve body just can adopt the nut type structure like this, thereby realizes end face seal, reaches the loose joint purpose.At output terminal, the seal ring sub-fraction is positioned at the end face chamfering of output terminal, and all the other major parts are in the valve body outside.The seal ring outside is furnished with an adapter sleeve equally.The conical surface of adapter sleeve matches with the nut conical surface of its outside.During installation, the neat mutually or pipe of pipe end face and seal ring end face exceeds a bit slightly, thereby forms end face seal, makes valve have the loose joint function with this.
In addition, the two ends of valve respectively have an adapter sleeve, and it is the cone shaped opening ring of being made by steel, and its internal surface has annular tooth.In the installation process, turn plug screw and nut respectively, they then promote adapter sleeve and come the crush seal circle, make it to play the effect of sealing pipe.When further tightening plug screw and nut, then adapter sleeve will slide along the conical surface that cooperates plug screw and nut with it, thereby adapter sleeve produces radial contraction, with its simultaneously the annular tooth of its internal surface be carved into outer tube surface, then pipe and valve are fixed together securely.Thereby make the joint sealing load greater than 2.4MPa, axially bear pulling force greater than 13000 newton.
Description of drawings:
1---valve body 2---seal ring
3---adapter sleeve 4---plug screw
5---nut 6---pipe
Embodiment:
The stop valve that adopts on supply channel.As shown in drawings, successively plug screw 4, adapter sleeve 3 and seal ring 2 are enclosed within on the pipe 6, are inserted into then in the input end of valve body, tighten plug screw.Successively nut 5, adapter sleeve 3 and seal ring 2 are enclosed within on another root pipe 6 again, place it in the output terminal of valve body then, again tightening nuts.
Advantage of the present utility model:
1. pipe is without mantle fiber when installing, and is time saving and energy saving. Valve can not when mounted
Generation is broken.
2. owing to adopt the loose joint structure, form one dual-purpose, save at pipe Lu Shangke
Economize union.
3. good seal performance, the reliability height.
4. compact structure is in light weight.
Claims (1)
- Pipe is without the direct insertion loose joint valve of mantle fiber during a kind of the installation, the input end that it is characterized in that valve body is to belong to plug screw type structure, seal ring is arranged in valve body, the outside is furnished with an adapter sleeve, the conical surface of adapter sleeve matches with the plug screw conical surface of its outside, output terminal adopts the nut type structure, the seal ring sub-fraction is positioned at the end face chamfering of output terminal, all the other major parts are in the valve body outside, the seal ring outside is furnished with an adapter sleeve, the conical surface of adapter sleeve matches with the nut conical surface of its outside, and adapter sleeve is the cone shaped opening ring, and its internal surface has annular tooth.
