Abstract
A check valve comprises a valve body, a valve cap, a sealing ball, a medium inlet and a medium outlet, wherein the sealing ball is installed in the valve body; the valve cap is installed on the valve body; an inclined guide track is arranged in the valve body; the lower end of the guide track is close to the medium inlet, and the higher end of the guide track is close to the medium outlet; the sealing ball is arranged on the guide track and can move along the guide track; the lower end of the track is hinged with a supporting plate; the supporting plate is installed at the bottom of the valve body; the higher end of the track is connected through a connecting plate; a kidney-shaped hole is formed in the connecting plate; one end of an adjusting rod is inserted into the kidney-shaped hole and is fixedly connected with the connecting plate; however, the adjusting rod can swing inside the kidney-shaped hole; the other end of the adjusting rod penetrates into a valve cap hole and is in threaded connection with the valve cap; a screwed plug is arranged at the upper end of the adjusting rod; and the screwed plug and the valve cap are in threaded connection, so that sealing is realized. The check valve has the benefits as follows: the adjusting rod is enabled to move up and down through rotation, so that the inclined angle of the guide track is changed, the pressure caused when the valve is opened is adjusted further, and the check valve is convenient to use for customers.
Description
Art
The present invention relates to a kind of safety check, particularly relate to a kind of ball check valve of adjustable cracking pressure.
Background technique
Existing ball check valve is when there is pressure pipeline medium entrance one end, ball sealer moves upward along ball orbit space, medium goes into circulation, during adverse current, ball sealer is fallen by eminence automatically due to inertia, because bulb diameter is greater than entrance diameter, and sphere and valve body inflow entrance just intimate contact, can seal action be played, stop fluid backflow.At present, the cracking pressure of ball check valve is all unadjustable, in the pipeline that some are special, needs, through changing cracking pressure to meet the demands, just to need integral replacing valve, use inconvenience.
Summary of the invention
In order to overcome the above-mentioned shortcoming of existing ball check valve, the invention provides a kind of can the safety check of regulating valve cracking pressure.
The technical solution adopted for the present invention to solve the technical problems is, a kind of safety check, comprise valve body, valve gap, ball sealer, medium entrance, media outlet, ball sealer is arranged in valve body, valve gap is arranged on valve body, the guide rail of one inclination is set in valve body, the low side of guide rail is near medium entrance, the high-end close media outlet of guide rail, ball sealer is placed on guide rail, and can move along guide rail, low side and a dunnage of track are hinged, dunnage is arranged on body base, the high-end of track is connected by connecting plate, connecting plate has a waist shaped hole, adjustable lever one end is inserted in waist shaped hole and is fixedly connected with connecting plate, but adjustable lever can swing in waist shaped hole, the adjustable lever the other end to penetrate in valve cover hole and is threaded connection with valve gap, plug is provided with in adjustable lever upper end, be threaded between plug with valve gap, realize sealing.
The invention has the beneficial effects as follows: by tuning pole, adjustable lever is moved up and down, thus change the angle of inclination of guide rail, and then pressure when regulating valve is opened, can step-less adjustment be realized, make valve Applicable scope wider, facilitate client to use.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is the plan view of Fig. 1.
In figure: 1. valve gap; 2. plug; 3. valve cover hole; 4. adjustable lever; 5. guide rail; 6. ball sealer; 7. medium entrance; 8. media outlet; 9. valve body; 10. dunnage; 11. connecting plates; 12. waist shaped holes.
Embodiment
As Fig. 1, shown in 2, a kind of safety check, comprise valve body 9, valve gap 1, ball sealer 6, medium entrance 7, media outlet 8, ball sealer 6 is arranged in valve body 9, valve gap 1 is arranged on valve body 9, the guide rail 5 of one inclination is set in valve body 9, lead the low side of 5 rails near medium entrance 7, the high-end close media outlet 8 of guide rail 5, ball sealer 6 is placed on guide rail 5, and can be extended down to guide rail 5 and move, low side and a dunnage 10 of track 5 are hinged, dunnage 10 is arranged on bottom valve body 9, the high-end of track 5 is connected by connecting plate 11, connecting plate 11 has a waist shaped hole 12, adjustable lever 4 one end is inserted in waist shaped hole 12 and is fixedly connected with connecting plate 11, but adjustable lever 4 can swing in waist shaped hole 12, adjustable lever 4 the other end to penetrate in valve cover hole 3 and is threaded connection with valve gap 1, plug 2 is provided with in adjustable lever 4 upper end, be threaded between plug 2 with valve gap 1, realize sealing.
After medium enters from medium entrance 7, promote ball sealer 6 thus Open valve, behind the angle of inclination of adjustment guide rail 5, also namely have adjusted the cracking pressure of valve, achieve step-less adjustment.
