Abstract
(B, ) the utility model provides a hangingly in small -bore valve clack can dismantle check valve fast, including valve body, valve gap, valve clack, the round pin axle, its characterized in that: valve body inside sets up a recess, the one end of valve clack is opened there is the through -hole, the round pin axle passes the through -hole is placed in in the recess the valve gap bottom is equipped with a boss, works as the valve gap with when the valve body cooperatees, the boss is pressed on the terminal surface of recess. Compared with the prior art, the utility model discloses a round pin axle is placed inside the valve body, has reduced by possible revealing a little to only need pull down the valve gap, can accomplish whole valve dismouting, convenient and fast has reduced the installation maintenance cost. (B, )
Description
Technical field
the utility model relates to safety check technical field, especially relates to a kind of small-bore flap internal hanging type quick release safety check.
Background technique
safety check is as a kind of common valve, and market demand is huge.But what now commercially use more safety check mostly to adopt has two kinds of structures, and one is bearing pin external structure, and this structure valve easily produces leakage.Another kind of structure adopts rocking bar hanger to connect, and be fixed by bolts on a boss of valve body, this structure disassembly process all compares to waste time and energy.
Model utility content
in order to overcome above deficiency, the purpose of this utility model is to provide a kind of small-bore flap internal hanging type quick release safety check, it can avoid the safety check of bearing pin external structure, the leakage problem of generation, and can solve bearing pin embedding structure safety check produce do not allow dismounting problem.
for achieving the above object, the utility model can adopt following technological scheme: a kind of small-bore flap internal hanging type quick release safety check, comprise valve body, valve gap, flap, bearing pin, described valve inner arranges a groove, and one end of described flap has through hole, described bearing pin passes described through hole and is placed in described groove, bottom described valve gap, be provided with a boss, when described valve gap matches with described valve body, described boss is pressed in the upper-end surface of described groove.
further, the two ends of described bearing pin are provided with axle sleeve.
compared with present technology, the beneficial effects of the utility model are:
1, adopt technical solutions of the utility model, bearing pin is placed on valve inner, decreases a possible leak point.
2, adopt technical solutions of the utility model, only need pull down valve gap, whole valve dismounting can be completed, convenient and swift, decrease installation and maintenance cost.
according to hereafter by reference to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Accompanying drawing explanation
hereinafter describe specific embodiments more of the present utility model with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference character identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:
fig. 1 is structural representation of the present utility model;
fig. 2 is the enlarged partial sectional view in the utility model A-A direction.
Embodiment
below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
small-bore flap internal hanging type quick release safety check as depicted in figs. 1 and 2, comprise valve body 1, valve gap 3, flap 2, bearing pin 4, described valve body 1 inside arranges a groove 5, and one end of described flap 2 has through hole, is provided with a boss 6 bottom described valve gap 3.During installation, bearing pin 4 is passed described through hole and is placed in described groove 5, and be then arranged on by valve gap 3 on described valve body 1, described boss 6 is pressed in the upper-end surface of described groove 5, avoids when flap 2 moves and comes off in groove.During dismounting, only need pull down described valve gap 3, from described groove, take out the work that namely bearing pin 4 and flap 3 complete whole dismounting.
in a specific embodiment of the present utility model, the two ends of described bearing pin 4 are provided with axle sleeve 7.The use of axle sleeve avoids flap moving axially in groove 5, makes the work that safety check is more stable.
so far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
Claims (2)
1. a small-bore flap internal hanging type quick release safety check, comprise valve body (1), valve gap (3), flap (2), bearing pin (4), it is characterized in that: described valve inner arranges a groove (5), one end of described flap (2) has through hole, described bearing pin (4) is through described through hole and be placed in described groove (5), a boss (6) is provided with bottom described valve gap, when described valve gap (3) matches with described valve body, described boss is pressed in the upper-end surface of described groove (5).
