Description
Technical field
The utility model relates to field of fluid control, specifically, particularly relates to a kind of one-way non-return control valve unit.
Background technique
Safety check relies on medium itself to flow and automatic opening-closing flap, prevent the valve that medium flows backwards, belong to a kind of automatic valve, when under the fluid pressure action a direction flowing, flap is opened, when fluid flows, because the pressure of fluid and the deadweight of flap make flap act on valve seat, thus cut off the flowing of fluid in the other direction.The Swing check valve that wherein widely used flap rotates around the shaft exists when the valve is closed, reverse flow of fluids speed is fast, impact force larger is instantaneously produced to valve seat and flap, simultaneously with water hammer, easily make pipe damage, reduce the working life of valve, widely used Swing check valve prevents valve rapid-closing by increasing damping device in the market, but this type of damping device general structure is complicated, and expend height, popularity rate is low.
Summary of the invention
The utility model discloses a kind of one-way non-return control valve unit, soon, easily producing water hammer, baroque problem for solving closure of check ring in conventional art.
The utility model is achieved through the following technical solutions:
A kind of one-way non-return control valve unit, comprise valve body, valve gap, valve seat, flap, valve gap is provided with above described valve body, be bolted to connection between the two, described valve body comprises inlet passage, outlet passage, chamber, the bottom of described inlet passage is provided with valve seat, rocking bar is provided with in described chamber, one end of described rocking bar is fixedly connected with described chamber by rotating shaft, the other end has been bolted flap, described flap surface is provided with the diaphragm seal of the integral property with flap, the inner side of described outlet passage is provided with pressure lobe device, described pressure lobe device comprises a brace, two supports, a cross bar, be flexibly connected by brace between described flap with described pressure lobe device.
Pad is provided with between described valve body and described valve gap.
The two ends of described support are all fixed with resilient pad.
Described resilient pad is fixed at the upper and lower end of described outlet passage.
Cross bar is provided with between described two supports.
Described cross bar can carry out upper and lower slip between described support.
Described brace one end and described flap hinged, the other end is fixedly connected with described cross bar.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by being provided with the diaphragm seal with flap one in flap surface, when guaranteeing that flap and inlet passage close, fluid through gap reflux, cannot improve the sealing of one way stop peturn valve; And when fluid forces flap Unscrew, due to flap being hinged with brace, brace promotes on cross bar sliding, when fluid stops circulation, and fluid generation reflux, fluid forces flap is closed to inlet passage direction, cross bar glides to flap generation resistance, prevents flap to be rapidly to inlet passage and closes, and then produce water hammer, valve body is produced to the problem of greater impact power, extend the working life of valve; Pressure valve device is simpler than general buffer unit structure simultaneously, is easy to install, and can widely use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pressure valve device of the present utility model.
In figure: 1, valve body; 2, valve gap; 3, valve seat; 4, flap; 5, bolt; 6, inlet passage; 7, outlet passage; 8, chamber; 9, rocking bar; 10, rotating shaft; 11, diaphragm seal; 12, brace; 13, support; 14, support; 15, cross bar; 16, pad; 17, resilient pad.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of one-way non-return control valve unit, comprise valve body 1, valve gap 2, valve seat 3, flap 4, valve gap 2 is provided with above described valve body 1, be fixedly connected with by bolt 5 between the two, described valve body 1 comprises inlet passage 6, outlet passage 7, chamber 8, the bottom of described inlet passage 6 is provided with valve seat 3, rocking bar 9 is provided with in described chamber 8, one end of described rocking bar 9 is fixedly connected with described chamber 8 by rotating shaft 10, the other end is connected with flap 4 by bolt 5, described flap 4 surface is provided with the diaphragm seal 11 of the integral property with flap 4, the inner side of described outlet passage 7 is provided with pressure lobe device, described pressure lobe device comprises a brace 12, two supports 13, 14, a cross bar 15, be flexibly connected by brace 12 between described flap 4 with described pressure lobe device.
Pad 16 is provided with between described valve body 1 and described valve gap 2.
The two ends of described support 13,14 are all fixed with resilient pad 17.
Described resilient pad 17 is fixed at the upper and lower end of described outlet passage 7.
Cross bar 15 is provided with between described two supports 13,14.
Described cross bar 15 can carry out upper and lower slip between described support 13,14.
Described brace 12 one end and described flap 4 hinged, the other end is fixedly connected with described cross bar 15.
Utility model works principle is: when fluid flows through valve, mobilization force due to fluid self makes fluid impact flap 4, because flap 4 is connected by bolt 5 with rocking bar 9, and then horizontal Driving force is produced to rocking bar 9, simultaneously because the other end of rocking bar 9 is connected with rotating shaft 10, flap 4 and rocking bar 9 be 10 rotations around the shaft, further, brace 12 on flap 4 promotes cross bar 15 at support 13, ascending motion is there is between 14, fluid enters chamber 8, when the fluid in pipeline stops flowing, the situation of the fluid generation reflux in valve, thrust is produced to flap 4, now flap 4 moves to inlet passage 6 direction, because flap 4 drives the equidirectional motion of brace 12, cross bar 15 is then driven at support 13 by brace 12, move downward between 14, and then reciprocal resistance is produced to flap 4, flap 4 is made not produce the phenomenon of water hammer because of quick-make, avoid because flap 4 impacts inlet passage 6 and impact force is produced to valve body 1, and then the problem of damage valve.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
