Abstract
The invention discloses a novel swing check valve, relating to a check valve. The novel swing check valve consists of a valve cap (1), a hinge pin (2), a rocking bar (3), a valve clack (4), a valve body (5) and an auxiliary valve (6), wherein the valve cap (1) is arranged on the upper end of the valve body (5), the hinge pin (2) is arranged on the upper end of the interior of the valve body (5), the rocking bar (3) is connected with the hinge pin (2), the auxiliary valve (6) is arranged on the lower side of the valve clack (4), and the valve clack (4) is connected with the rocking bar (3). The auxiliary valve is additionally arranged, thus the novel swing check valve has the advantages that the water hammer which damages a pipeline system and is caused by the traditional similar check valve is solved; the use range of the check valve is expanded; and the novel swing check valve is convenient to use.
Description
Technical field:
The present invention relates to a kind of safety check, be specifically related to a kind of novel Swing check valve.
Background technique:
Safety check is the self-acting valve that prevents that the medium in the pipeline from flowing backwards, and the bottom valve that pump sump closes also belongs to the safety check class.Its open-shut device is opened voluntarily or is closed by media flow and strength, flows backwards to prevent medium.Safety check belongs to the self-acting valve class, opens during as the pipe-line system following current, and the valve of closing during adverse current is mainly used in and prevents that medium from flowing backwards, and prevents that pump and drive motor from reversing and container inner medium is released; Using the most at present, flap centers on the Swing check valve of valve body bearing pin rotation and the Lift check valve that flap moves along the valve body vertical center line, but the valve of above 2 kinds of structures all exists when closing medium refluence speed to reduce to zero rapidly from maximum, cause to press rapidly in pipe water pipe one side and raise, thereby produce the water hammer that pipe-line system is had destruction, so it is 50～500mm that general safety check is produced bore, but such structural limitations the using scope of safety check.
Summary of the invention:
The purpose of this invention is to provide a kind of novel Swing check valve, it has set up secondary valve, can solve traditional similar safety check and can produce the water hammer that pipe-line system is had destruction, has enlarged the using scope of safety check, more convenient use.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it is made up of valve gap 1, bearing pin 2, rocking bar 3, flap 4, valve body 5 and secondary valve 6, valve gap 1 is arranged on valve body 5 upper ends, bearing pin 2 is arranged on valve body 5 inner upper end, rocking bar 3 is connected with bearing pin 2, secondary valve 6 is arranged on flap 4 downsides, and flap 4 is connected with rocking bar 3.
Described secondary valve 6 is made up of secondary valve gap 6-1, seal ring 6-2, piston 6-3, piston rod 6-4, secondary flap 6-5 and auxiliary valve body 6-6, secondary valve gap 6-1 is arranged on the upper end of auxiliary valve body 6-6, be provided with seal ring 6-2 between secondary valve gap 6-1 and the auxiliary valve body 6-6, piston 6-3 is arranged on the inner upper end of auxiliary valve body 6-6, piston rod 6-4 is arranged on the lower end, central position of piston 6-3, and secondary flap 6-5 is arranged on the outside of piston rod 6-4.
The present invention sets up secondary valve 6 on former Swing check valve flap 4, secondary valve 6 is installed in main valve flap 4 downsides or both sides and uses scyewed joint, during medium proper flow valve opening, pressure medium is opened secondary valve 6, medium flows into the main valve outlet end by secondary valve 6 apertures, make the release of main intake valve end, main valve flap 4 is opened, and pressure tends to balance before and after the main valve; During medium counter flow, main valve flap 4 quick closedown under the counter-flow media effect, and secondary valve 6 valve body tops are cushion dashpot, secondary valve 6 valve gaps screw in valve body top, and it has covered an aperture, secondary flap 6-5 and its piston rod 6-4 of secondary valve 6 are set with certain interval, adopting O RunddichtringO 6-2 sealing between piston 6-3 and the cushion dashpot, is plane sealing between piston 6-3 bottom and the secondary flap 6-5; When secondary flap 6-5 closes with main valve flap 4 and when closing, effect because of secondary valve gap 6-1 aperture, medium flows into secondary valve 6 cushion dashpot upper cavities gradually by aperture, and a part of medium flows backwards by the gap between secondary flap 6-5 and the piston rod 6-4, so the piston 6-3 of secondary valve 6 slowly closes.
The present invention has set up secondary valve, can solve traditional similar safety check and can produce the water hammer that pipe-line system is had destruction, has enlarged the using scope of safety check, more convenient use.
Description of drawings:
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the structural representation of secondary valve 6 among the present invention.
Embodiment:
With reference to Fig. 1-2, this embodiment is by the following technical solutions: it is made up of valve gap 1, bearing pin 2, rocking bar 3, flap 4, valve body 5 and secondary valve 6, valve gap 1 is arranged on valve body 5 upper ends, bearing pin 2 is arranged on valve body 5 inner upper end, rocking bar 3 is connected with bearing pin 2, secondary valve 6 is arranged on flap 4 downsides, and flap 4 is connected with rocking bar 3.
Described secondary valve 6 is made up of secondary valve gap 6-1, seal ring 6-2, piston 6-3, piston rod 6-4, secondary flap 6-5 and auxiliary valve body 6-6, secondary valve gap 6-1 is arranged on the upper end of auxiliary valve body 6-6, be provided with seal ring 6-2 between secondary valve gap 6-1 and the auxiliary valve body 6-6, piston 6-3 is arranged on the inner upper end of auxiliary valve body 6-6, piston rod 6-4 is arranged on the lower end, central position of piston 6-3, and secondary flap 6-5 is arranged on the outside of piston rod 6-4.
This embodiment is set up secondary valve 6 on former Swing check valve flap 4, secondary valve 6 is installed in main valve flap 4 downsides or both sides and uses scyewed joint, during medium proper flow valve opening, pressure medium is opened secondary valve 6, medium flows into the main valve outlet end by secondary valve 6 apertures, make the release of main intake valve end, main valve flap 4 is opened, and pressure tends to balance before and after the main valve; During medium counter flow, main valve flap 4 quick closedown under the counter-flow media effect, and secondary valve 6 valve body tops are cushion dashpot, secondary valve 6 valve gaps screw in valve body top, and it has covered an aperture, secondary flap 6-5 and its piston rod 6-4 of secondary valve 6 are set with certain interval, adopting O RunddichtringO 6-2 sealing between piston 6-3 and the cushion dashpot, is plane sealing between piston 6-3 bottom and the secondary flap 6-5; When secondary flap 6-5 closes with main valve flap 4 and when closing, effect because of secondary valve gap 6-1 aperture, medium flows into secondary valve 6 cushion dashpot upper cavities gradually by aperture, and a part of medium flows backwards by the gap between secondary flap 6-5 and the piston rod 6-4, so the piston 6-3 of secondary valve 6 slowly closes.
