Description
Technical field
The invention belongs to the pipeline valve technology, be specifically related to a kind of pressure security bleeder valve of protecting webmaster.
Background technique
The pipeline bleeder valve is a kind of valve of protecting the pressure security of webmaster.When the pressure of pipeline exceeded setting pressure, this valve opening gave vent to hydraulic pressure, the protection pipeline.The bleeder valve of present domestic manufacturing all is that direct-acting type changes up pass type or leading type bleeder valve soon.Promptly after pipeline had the water hammer high pressure wave to arrive, direct-acting type changes up the pass type soon can open (but the leading type opening time is slow relatively) by induction pipe pressure fast, but after pipeline pressure returned to below the setup pressure value, bleeder valve can quick closedown.The fast opening and closing of above-mentioned valve causes pipe network to form the secondary instantaneous high pressure; This secondary instantaneous high pressure forms owing to the bleeder valve closing velocity is too fast, and pipe network is also had certain destruction.
Summary of the invention
The object of the present invention is to provide a kind of bleeder valve, the quick unlatching release when it can realize pressure protect, when closing, slowly action is closed, thereby overcomes the defective of above-mentioned existing bleeder valve.
The scheme of technology of the present invention is: fast-opening slowly-closing water hammer bleeder valve, and it comprises valve body, connects valve gap on the valve body; The valve body inner flow passage is provided with valve seat; Be provided with in the valve body can with the flap of the switching of valve base sealing, flap is connected with valve rod, it also comprise pass valve gap and with valve gap between the sleeve of the end opening that is fixedly connected; Valve rod movably stretches in the sleeve, seals between valve rod sidewall and the sleeve inner hole wall; Connect the driven medium pipeline on the sleeve wall, the driven medium pipeline communicates with the sleeve endoporus; The other end of pipeline connects UNICOM's container, is connected with one-way throttle valve on the pipeline.
Said sleeve endoporus is connected with axle sleeve, contact guidance sealing between axle sleeve and the valve rod.
Be provided with preloading spring between flap and the valve gap inwall.
The lid inwall is connected with guide sleeve, is arranged with pressing plate in the guide sleeve, and preloading spring is located between flap and the pressing plate; Pressing plate contacts with the pretightening force controlling mechanism.
Said pretightening force controlling mechanism comprises the adjusting screw rod that passes valve gap, and adjusting screw rod is connected with adjusting nut, and the adjusting screw rod end contacts with pressing plate.
Limit on a sleeve step and valve gap simultaneously contacts spacingly, establishes draw-in groove on the sleeve wall, establishes snap ring in the draw-in groove, and snap ring contacts spacing with the valve gap another side.
Sleeve passes pressing plate, and preloading spring is enclosed within sleeve outer wall.
Above-mentioned one-way throttle valve is when valve closing, to realize the damping throttling, and during valve opening, one-way valve is opened.
Above-mentioned driven medium is a hydraulic oil, and container is a fuel tank.
The working principle of this valve is: when upstream pressure is higher than the security settings pressure of water hammer bleeder valve, (can be the pressure of preloading spring; Also can pass through driven medium and container setting); After the safety pressure value that spring is set; Hydraulic type fast-opening slowly-closing system does not hinder the opening process of spool basically, and the assurance valve can be opened fast and carry out pressure release, eliminates the safety of water hammer protection pipe network.
Be lower than the safety pressure value of water hammer bleeder valve setting when upstream pressure after, hydraulic type fast-opening slowly-closing system can control the closing velocity of spool, close slowly by valve through the flow of control oil channel, and closing velocity is adjustable.
The water hammer bleeder valve can be opened the elimination water hammer fast, and slow Slow Close has simultaneously avoided producing owing to valve closing is too fast the secondary water hammer.It is simple and compact for structure.
Description of drawings
Fig. 1 water hammer bleeder valve structural representation.
Embodiment
As shown in Figure 1, connect valve gap 2 on the valve body 1, valve body 1 inner flow passage is provided with valve seat 2, be provided with in the valve body can with the flap 3 of the switching of valve base sealing, said structure is existing routine techniques.Flap 3 is connected with valve rod 14, and the sleeve 11 of offering hole 15, one end openings on the valve gap 2 passes hole 15 and sealing with it on the valve gap 2, and sealing configuration can be the sealing configuration of seal ring or seal ring.Limit on the sleeve 11 step 17 and valve gap simultaneously contacts spacingly, establishes draw-in groove 18 on the sleeve wall, establishes snap ring 19 in the draw-in groove 18, and snap ring contacts spacing with the valve gap another side.
The opening of sleeve 11 is in valve body 1, and the open section of the endoporus 16 of sleeve 11 is connected with axle sleeve 5.
Axle sleeve 5 with seal being connected between the surface of contact of endoporus 16 of sleeve 11, sealing configuration can be the sealing configuration of seal ring or seal ring.
Valve rod 14 passes axle sleeve 5, extend in the endoporus 16 of sleeve 11, is provided with sealing configuration between the surface of contact of valve rod 14 and axle sleeve 5, as establishing seal groove at axle sleeve 5 inner hole walls, establishes seal ring in the seal groove.
Valve gap 8 inwalls are connected with guide sleeve 7, are arranged with pressing plate 6 in the guide sleeve 7, and preloading spring 4 is located between flap 3 and the pressing plate 6; Pressing plate 6 contacts with the pretightening force controlling mechanism.Sleeve 11 passes pressing plate 6, and preloading spring 4 is enclosed within sleeve outer wall.
The pretightening force controlling mechanism comprises the adjusting screw rod 10 that passes valve gap 8, and adjusting screw rod 10 is connected with adjusting nut 9, and adjusting screw rod 10 ends contact with pressing plate 6.Adjusting nut 9 is fixed on the valve gap 8.
Sleeve 11 is connected with hydraulic control mechanism.Like Fig. 1, shown in 2, hydraulic control mechanism comprises connection driven medium pipeline 21 on the sleeve wall, and driven medium pipeline 21 communicates with sleeve endoporus 16; The other end of pipeline 21 connects UNICOM's container 13 (fuel tanks), is connected with one-way throttle valve 12 on the pipeline.
In the water hammer bleeder valve valve spring is housed, through adjusting screw rod can setting spring elastic force, the elastic force value of this spring corresponding the force value (safety pressure setting value) before the valve.
Oil pressure fast-opening slowly-closing system is connect etc. by fuel tank, one-way throttle valve 12 and pipe and forms.When hydraulic oil flowed into fuel tank in sleeve 11, one-way throttle valve 12 runner spaciousnesses were without hindrance.When hydraulic oil was flowed in the sleeve 11 by fuel tank, one-way throttle valve 12 played a part current limliting, and hydraulic oil can only slowly flow in the sleeve, thus flap 3 can only move slowly in closing closed procedure with valve rod 14, until closing.
The structure that the safety pressure setting value is set through driven medium and container can be: prefastening force spring is located between valve rod 14 end faces and sleeve endoporus 16 end faces of sleeve 11; Perhaps on pipeline 21, connect one-way pressure valve.
