Abstract
The invention discloses an extensible ventilating valve which comprises a valve body. The valve body is composed of a valve body fixed section and a valve body moving section. The valve body fixed section comprises a fixed-section valve seat and a fixed-section tube mounted on the fixed-section valve seat. The valve body moving section comprises a moving-section valve seat and a moving-section tube mounted on the moving-section valve seat. A valve plate capable of opening or closing the fixed-section tube is arranged on the valve body fixed section. A plurality of reset springs are arranged between the fixed-section valve seat and the moving-section valve seat. The tube-body outer diameter of the fixed-section tube is slightly smaller than that of the moving-section tube, so that the fixed-section tube can extend into the moving-section tube when the valve body moving section moves toward the valve body fixed section along the axial direction of the valve body. A pipeline sealing ring capable of deforming in an extensible manner along the axial direction of the valve body is arranged between the moving-section tube and the fixed-section tube in a sleeved manner. The extensible ventilating valve has the advantages of capability of extensible displacement along the axial direction of the valve body and high working efficiency.
Description
Technical field
The present invention relates to a kind of scalable Ventilating valve in the deduster system.
Background technique
Present stage, in the deduster system, the structure that be used for to connect the Ventilating valve of two adjacent channels is: comprise integrated valve body, and be arranged on the valve body, can realize valve open or the valve disc of closing.The shortcoming of this Ventilating valve is: when the pipeline in the deduster system is removable pipeline, after removable pipeline moves to the Ventilating valve position, and can have the gap between the 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 influence working efficiency.
Summary of the invention
The purpose of this invention is 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 take place.
For achieving the above object, the present invention has adopted following technological scheme: described a kind of scalable Ventilating valve, comprise valve body, valve body is made up of valve body holding part and the valve body section of movement, the valve body holding part comprises the holding part valve seat and is installed on holding part body on the holding part valve seat, the valve body section of movement comprises mobile section valve seat and is installed on the mobile section body that moves on the section valve seat that 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 section of movement is axially moved to the valve body holding part along valve body, the holding part body can stretch in the mobile section body, also is arranged with the seal for pipe joints circle that telescopic shape change can axially take place along valve body between mobile section body and holding part body.
Further, aforesaid a kind of scalable Ventilating valve, wherein: the bellows of telescopic shape change for axially taking place 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 mobile section body curved flanging that bends inwards.
By the enforcement of technique scheme, the present invention has can be along valve shaft to the advantage that axial stretching displacement and high working efficiency take place.
Description of drawings
Fig. 1 is the structural representation of a kind of scalable Ventilating valve of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1 as showing, described a kind of scalable Ventilating valve, comprise valve body, valve body is made up of valve body holding part and the valve body section of movement, the valve body holding part comprises holding part valve seat 1 and is installed on holding part body 2 on the holding part valve seat 1, the valve body section of movement comprises mobile section valve seat 3 and is installed on the mobile section body 4 that moves on the section valve seat 3 that 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 section of movement is axially moved to the valve body holding part along valve body, holding part body 2 can stretch in the mobile section body 4, also is arranged with the seal for pipe joints circle that telescopic shape change can axially take place along valve body between mobile section body 4 and holding part body 2; In the present embodiment, the bellows 7 of telescopic shape change for axially taking place 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 the phase mutual friction of holding part body 2 and mobile section body 4 like this on the holding part body 2, improve service life of equipment.In practical operation, earlier valve body is engaged with air-suction duct 8 by holding part valve seat 1, again the valve body section of movement is revolved the external force that adds left, the valve body section of movement axially is moved to the left along valve body, Returnning spring 6 is compressed in the process that the valve body section of movement is moved to the left, and produces restoring force to the right; Then removable air-suction duct 9 is moved to desired location---namely be positioned at same axial location with valve after, unclamp the external force that acts on the valve body section of movement, at this moment, the valve body section of movement moves right under Returnning spring 6 restoring force effect to the right, with removable air-suction duct 9 fluid-tight engagement.The present invention has can be along valve shaft to the advantage that axial stretching displacement and high working efficiency take place.
