Abstract
The utility model provides an axial compressor is adjustable to delay closed check valve, which comprises the following components: a valve body, a spring, the valve clack, a valve sea, adjust the case, bearing and gland, be equipped with a baffle in the valve body, first cavity and second cavity are kept apart into with the valve body to this baffle, offer the passageway that is used for feeding through first cavity and second cavity on the baffle, the spring has set gradually between the opening part valve body port of first cavity place passageway, case and disk seat, it rotatably sets up in the passageway belongs to the baffle perpendicularly to adjust the case, the one end of adjusting the case lies in the passageway, the other end of adjusting the case loops through the bearing and fixes in the valve body outside with the gland, and still offer a through -hole that is used for adjusting passageway flow area on the regulation case that lies in the passageway. Through set up the flow area who adjusts the case and adjust the passageway on the passageway to the pressure of the medium backward flow in the control second cavity, thus realize adjusting the speed of closing the check valve, the utility model discloses simple structure is very practical.
Description
Technical field
The utility model relates to valve technology field, more specifically, particularly relates to a kind of axial flow adjustable slow-closure formula safety check.
Background technique
Safety check is quite general in the prior art, but technically also there is certain room for improvement what control safety check, particularly realizes at low cost controlling the speed of safety check, and this is a problem needing to improve.
Model utility content
In view of the above, the purpose of this utility model is to provide a kind of axial flow adjustable slow-closure formula safety check, is to carry out the problem that speed effectively regulates for solving safety check in prior art closing.
For achieving the above object and other relevant objects, the utility model provides following technological scheme:
A kind of axial flow adjustable slow-closure formula safety check, comprise valve body, spring, flap, valve seat, regulating spool, bearing and gland, a dividing plate is provided with in valve body, valve body is isolated into the first cavity and the second cavity by this dividing plate, dividing plate offers the passage for being communicated with the first cavity and the second cavity, spring is disposed with between the opening valve body port of the first cavity place passage, spool and valve seat, regulating spool is rotatably vertically set in the dividing plate of passage place, one end of regulating spool is positioned at all, the other end of regulating spool is fixed on valve body outside by bearing and gland successively, and on the regulating spool being positioned at passage, also offer one for regulating the through hole of channel cross-sectional flow area.
Preferably, the guide groove that one supplies flap movement is provided with around access portal in the first cavity, one end of spring is arranged on the opening of the first cavity internal channel, and the other end is arranged on the side of flap, the opposite side of flap be suitable for closed first cavity determine lean against on valve seat.
Preferably, passage is circular channel.
Preferably, the through hole offered in one end of regulating spool is manhole, the diameter of manhole and the equal diameters of circular channel.
As mentioned above, the utility model has following beneficial effect: the circulation area regulating passage by arranging regulating spool on passage, thus controls the pressure of the medium back flow in the second cavity, thus realizes regulating to the speed of closure of check ring, the utility model structure is simple, very practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the scheme in the utility model embodiment, be briefly described to describing the required accompanying drawing used in specific embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those skilled in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the main TV structure figure of a kind of axial flow of the utility model adjustable slow-closure formula safety check.
Fig. 2 is shown as the sectional structure chart of regulating spool.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on embodiment of the present utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, belong to the scope of the utility model protection.
Please refer to Fig. 1, for a kind of main TV structure figure of axial flow adjustable slow-closure formula safety check, as shown in the figure, this axial flow adjustable slow-closure formula safety check comprises valve body 1, spring 2, flap 3, valve seat 4, regulating spool 5, bearing 6 and gland 7, a dividing plate is provided with in valve body 1, valve body 1 is isolated into the first cavity 11 and the second cavity 12 by this dividing plate, dividing plate 8 offers the passage 9 for being communicated with the first cavity 11 and the second cavity 12, spring 2 is disposed with between opening valve body 1 port of the first cavity 11 place passage 9, spool and valve seat 4, regulating spool 5 is rotatably vertically set in passage 9 place dividing plate 8, one end of regulating spool 5 is positioned at passage 9, the other end of regulating spool 5 is fixed on valve body 1 outside by bearing 6 and gland 7 successively, and on the regulating spool 5 being positioned at passage 9, also offer one for regulating the through hole 10 of passage 9 circulation area.
Particularly, at composition graphs 1, passage 9 around openings in the first cavity 11 is provided with the guide groove that supplies flap movement, one end of spring is arranged on the opening of the first cavity 11 internal channel 9, the other end is arranged on the side of flap, the opposite side of flap be suitable for closed first cavity 11 determine lean against on valve seat.
In concrete enforcement, this passage 9 is circular channel, referring again to Fig. 2, for the sectional structure chart of regulating spool, as shown in the figure, the through hole 10 offered in one end of regulating spool is manhole, the diameter of this through hole is identical with the diameter of circular channel, passage can be closed completely and open.
Incorporated by reference to Fig. 1, the principle of such scheme is, when the end having medium by valve body 1 enters the first cavity 11, the pressure of medium itself can promote spool extrusion spring 2, thus make medium enter in the first cavity 11 by flap 3, and entered in the second cavity 12 by the passage on dividing plate 8, thus realize medium and be smoothly through valve body 1, when the medium entering the first cavity 11 reduces or stops, the pressure promoting flap 3 extrusion spring 2 diminishes, pressure medium in the reaction force and the second cavity 12 of spring 2 will promote flap 3 and move towards valve seat 4, when flap 3 leans against on valve seat 4 completely surely, cut-off is flowed by medium, practical part of the present utility model is the area being changed passage flow by the regulating spool 5 be rotatably provided in passage, thus regulate medium in the second cavity 12 to flow into the speed of the first cavity 11, thus adjustment pressure medium, and then realize the speed of flap 3 to valve seat 4 movement, namely the speed of closure of check ring is realized, thus play the effect that can slowly regulate.
In sum, the utility model achieves the adjustment to closure of check ring speed very dexterously.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
