Description
Technical field
Terminal core pipe valve of the invention belongs to valve field, is that the branch of the core pipe stem nut series of my original invention is whole
Core pipe valve series is held, terminal drainage valve, safety valve are related to.
Background technique
Existing terminal drainage valve, open and close torque are big.
Existing terminal security valve, spring are easy fatigue, erosion of the spring by medium, pressure medium under critical conditions
There is discontinuously leakage, is not suitable for heavy caliber.
Currently, acting on the safety valve in boiler, pressure vessel and other compression equipment with the direct load formula of compressed spring
Based on safety valve and pilot operated safety valve.Its Reliability of Microprocessor and performance quality are directly related to the safety of equipment and the person, and
It is closely related with energy conservation and environmental protection.
Compressed spring Direct loaded safety valve disadvantage: load lotus can change with unlatching, i.e., compression spring force is being opened
It is that gradient type increases during opening, causes to discharge unsmooth, Lift, drain time, speed can not Field adjustment；It was using
The fatigue variation of compression of metals spring is big in journey and keeps pressure limiting parameter fluctuation big, and often to adjust can guarantee the normal use, no
It then will appear drain charge in advance, or extend drain charge.
Pilot operated safety valve, the disadvantage is that: O-shaped sealing rubber ring temperature tolerance is poor；Structure is complicated, and manufacturing cost is high；Reliably
Property is influenced by main valve, auxiliary valve, power drive mechanism many factors；The poor sensitivity under the operating condition of low pressure and mass flow.
Large-scale drain valve opening and closing torque is larger, the mating actuator of some need, and opening and closing time is long.
Summary of the invention
The object of the present invention is to provide terminal core pipe valve, overcome the shortcomings of existing terminal valve, meet production need and
Energy conservation needs.
Terminal core pipe valve is mainly technically characterized by: valve core tube is that single head is connected to pressure vessel, press device and medium tube
The fixing piece of net is perpendicular to ground through the sleeve I of valve body, body cavity, II throat of sleeve for touching valve body；Valve core tube has
At least two radial recirculation holes and end spool；The annular of at least one sleeve throat of end spool and sleeve I and sleeve II
Valve seat constitutes sealing pair；Valve core tube and sleeve I are that shaft hole mode cooperates the setting of its engaging portion to seal；In I internal diameter of sleeve >=sleeve II
Diameter；Under the action of both direction potential energy, valve body makees axial reciprocating movement relative to valve core tube to realize opening and closing.
The axial inner ends face of the end spool is ligulate triangle slope surface.
The axial inner ends face of the end spool is also possible to spherical surface, can also be the conical surface；End spool and valve core tube pipe
Section part can be integrated, is also possible to two components and constitutes.
It is described that at least one piece of ring-shaped weight is set on valve body.
It is described that extension spring is set between spool tube end and valve body outside.
What the setting of the upper end outside valve core tube made valve body axial movement is fixed pulley and rope, and one end of rope connects sleeve
Pipe I, the other end connect pull ring.
I internal diameter of sleeve is greater than II internal diameter of sleeve, is successively set with a butterfly spring from bottom to up in spool tube end
And permanent magnet.
It is described that studs is set between I end of spool tube end and sleeve.
Described that electromagnet is arranged between I end of spool tube end and sleeve, plug one end of electromagnet connects outside sleeve I
Portion.
Bellows pressure chamber is arranged in the engaging portion of the valve core tube and sleeve I, and bellows pressure chamber inner cavity passes through valve core tube
The preceding pressure in radial communication hole and valve on ring wall communicates.
Bellows pressure chamber is arranged in the engaging portion of the valve core tube and sleeve I, and bellows pressure chamber inner cavity passes through communicating pipe
It is communicated with the preceding pressure of valve.
The elastic element, it is contemplated that they are adjusted axially in actual design.
The bellows can be metal bellows, be also possible to the nonmetallic bellows such as plastics.
In conclusion terminal core pipe valve of the invention has the active effect that
1, structure is simple, convenient for manufacture；
2, body cavity is convenient for cleaning；
3, long service life, cost performance are high；
4, it adapts to from miniature to the various bores of ultra-large type；
5, valve body is turned off formula to medium flow field as opening and closing element when closing valve, and opening and closing resistance is small；
Even if operability can be still good 6, under high-pressure medium state；
7, axial circulation, flow resistance is small, reduces energy consumption；
8, annual test is reduced, production efficiency is improved；
9, using reliable.

It puts.
This terminal core pipe valve belongs to from force control valve, is applied to safety relief, can use counterweight 708 when actually needed
Pressure release value is adjusted, can also be exerted a force on the mobile apparatus using extension spring to valve body 2, counterweight can also be added using permanent magnet
708 or permanent magnet add extension spring.
Embodiment nine
Referring to attached drawing 15,16, terminal core pipe valve described in the present embodiment, for discharging；The valve core tube 1 hangs down for fixing piece
Directly in ground it is coaxial from bottom to up through the sleeve I 2 of valve body 2 ', 2 inner cavity 200 of valve body, the II 2 " larynx of sleeve for touching valve body 2
Portion；There are two radial recirculation hole 103 and end spools 101 ' for valve core tube 1；The axial inner ends face of end spool 101 ' is ligulate
Triangle slope surface 100 ', outer end face are spherical surfaces；" ring-shaped valve seats 201 of throat constitutes sealing pair for end spool 101 ' and sleeve II 2；
Valve core tube 1 and sleeve I 2 ' for shaft hole mode cooperate its engaging portion that bellows pressure chamber 306 is arranged, and 306 inner cavity of bellows pressure chamber is logical
The preceding pressure for spending communicating pipe 600 and valve communicates, and triple valve 603 is arranged in the middle part of communicating pipe 600；101 ' top of end spool connection one
A umbrella shape part 101 ", it hides ash and keeps off the rain；At least one piece of ring-shaped weight 708 is set in 2 shoulder of valve body.
It is open state shown in attached drawing 15, at this point, the pressure medium of pipe network is normal, opens triple valve 603, bellows pressure
The thrust that pressure medium in power cabin 306 is formed is greater than the gravity from gravity+counterweight 708 of valve body 2, and valve body 2 is axial to be moved up, and tucks inside the sleeve
Pipe II 2 " ring-shaped valve seats 201 of throat leaves end spool 101 ', and medium is through recirculation hole 103, inner cavity 200 and sleeve II 2 " row
It puts.
It shown in attached drawing 16, is in off state, at this point, closing triple valve 603, and bleeds off in bellows pressure chamber 306
Pressure medium, since valve body 2 is from the gravity of gravity+counterweight 708, valve body 2 is axial to be moved down, " the ring-shaped valve seats of throat of sleeve II 2
201 are closely affixed with end spool 101 '.
The triple valve 603 of this terminal core pipe valve can be controlled remotely.
