Abstract
The utility model discloses a stretchable ventilation valve. The stretchable ventilation valve comprises a valve body, wherein the valve body is composed of a valve body fixed section and a valve body movable section, the valve body fixed section comprises a fixed section valve seat and a fixed section pipe body installed on the fixed section valve seat, the valve movable section comprises a movable section valve seat and a movable section pipe body installed on the movable section valve seat, a valve disk which is capable of opening or closing the fixed section pipe body is arranged on the valve body fixed section, a plurality of reset springs are arranged between the fixed section valve seat and the movable section valve seat, the outer diameter of the fixed section pipe body is slightly smaller than the inner diameter of the movable section pipe body so that the fixed section pipe body can stretch into the movable section pipe body when the valve body movable section moves towards the valve body fixed section in the axial direction of the valve body, and a pipeline seal ring which can stretch or contact in the axial direction of the valve body is further arranged between the movable section pipe body and the fixed section pipe body in a sleeved mode. The stretchable ventilation valve has the advantages of being capable of stretching or contracting in the axial direction and high in working efficiency.
Description
Technical field
The utility model relates to a kind of scalable Ventilating valve in duster system.
Background technique
Present stage, in duster system, be used to the structure of the Ventilating valve that connects two adjacent channels be: comprise integrated valve body, and be arranged on valve body, can realize valve open or the valve disc of closing.The shortcoming of this Ventilating valve is: when the pipeline in duster system is removable pipeline, after removable pipeline moves to the Ventilating valve position, and can have gap between Ventilating valve, generation is leaked out, for hidden danger has been buried in the safety in production of factory; And when there is error in the length dimension of removable pipeline, removable pipeline can't move to the Ventilating valve position and engage with Ventilating valve, greatly affect working efficiency.
The model utility content
The purpose of this utility model be to provide a kind of can be along valve shaft to a kind of scalable Ventilating valve that axial stretching displacement and high working efficiency occur.
For achieving the above object, the utility model has adopted following technological scheme: described a kind of scalable Ventilating valve, comprise valve body, valve body is comprised of valve body holding part and valve body mobile section, the valve body holding part comprises the holding part valve seat and is installed on the holding part body on the holding part valve seat, the valve body mobile section comprises the mobile section valve seat and is installed on the mobile section body on the mobile section valve seat, on the valve body holding part, is provided with the valve disc that can open or close the holding part body; Between holding part valve seat and mobile section valve seat, be provided with some Returnning springs; The body external diameter of holding part body is slightly less than the internal diameter of tube body of mobile section body, when the valve body mobile section is axially moved to the valve body holding part along valve body, the holding part body can stretch in the mobile section body, between mobile section body and holding part body, also is arranged with the seal for pipe joints circle of telescopic shape change can axially occur along valve body.
Further, aforesaid a kind of scalable Ventilating valve, wherein: the bellows of telescopic shape change for can axially occur along valve body in described seal for pipe joints circle, and an end of bellows is sheathed on the outer wall of mobile section body, and the other end of bellows is sheathed on the outer wall of holding part body.
Further, aforesaid a kind of scalable Ventilating valve, wherein: on the holding part body in order to the edge of the mouth of pipe that the stretches into the mobile section body curved flanging that bends inwards.
By the enforcement of technique scheme, the utlity model has can be along valve shaft to the advantage that axial stretching displacement and high working efficiency occur.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of scalable Ventilating valve described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1 if shown, described a kind of scalable Ventilating valve, comprise valve body, valve body is comprised of valve body holding part and valve body mobile section, the valve body holding part comprises holding part valve seat 1 and is installed on the holding part body 2 on holding part valve seat 1, the valve body mobile section comprises mobile section valve seat 3 and is installed on the mobile section body 4 on mobile section valve seat 3, on the valve body holding part, is provided with the valve disc 5 that can open or close holding part body 2; Between holding part valve seat 1 and mobile section valve seat 3, be provided with some Returnning springs 6; The body external diameter of holding part body 2 is slightly less than the internal diameter of tube body of mobile section body 4, when the valve body mobile section is axially moved to the valve body holding part along valve body, holding part body 2 can stretch in mobile section body 4, between mobile section body 4 and holding part body 2, also is arranged with the seal for pipe joints circle of telescopic shape change can axially occur along valve body; In the present embodiment, the bellows 7 of telescopic shape change for can axially occur along valve body in described seal for pipe joints circle, one end of bellows 7 is sheathed on the outer wall of mobile section body 4, the other end of bellows 7 is sheathed on the outer wall of holding part body 2, this bellows 7 is simple in structure, cost is low, and installation and maintenance are convenient; In the present embodiment, in order to the edge of the mouth of pipe that the stretches into mobile section body 4 curved flanging that bends inwards, can reduce like this phase mutual friction of holding part body 2 and mobile section body 4 on holding part body 2, improve service life of equipment.In practical operation, first valve body is engaged with air-suction duct 8 by holding part valve seat 1, then the valve body mobile section is revolved to the external force added left, the valve body mobile section axially is moved to the left along valve body, Returnning spring 6 is compressed in the process that the valve body mobile section is moved to the left, and produces restoring force to the right; Then removable air-suction duct 9 is moved to desired location---after namely with valve, being positioned at same axial location, unclamp the external force that acts on the valve body mobile section, now, the valve body mobile section moves right under Returnning spring 6 restoring force effect to the right, with removable air-suction duct 9 fluid-tight engagement.The utlity model has can be along valve shaft to the advantage that axial stretching displacement and high working efficiency occur.
