Abstract
The invention relates to an atmosphere exhaust valve. The atmosphere exhaust valve comprises a valve element, a valve seat and a valve deck, wherein the valve element is arranged inside the valve seat, a cage cover is arranged on the upper portion of the valve seat, the valve deck is hollow and is located above the cage cover, a guide sleeve and a valve deck gasket are arranged between the valve deck and the cage cover, the valve deck and the cage cover are fastened together through a fastening device, a support is arranged above the valve deck, a locking nut is arranged on the support, and a valve rod is connected between the locking nut and the valve element. According to the atmosphere exhaust valve, the over-entering and down-out mode is adopted, no crack is generated during atmosphere exhaust, the safety performance is high, noise is low, vibration is low, and market requirements are met.
Description
Technical field
The present invention relates to a kind of exhaust steam valve, be specifically related to a kind of air-out tube valve.
Background technique
In station boiler system, generally all adopt stop valve to sky exhaust, during valve closing, the pressure that spool bears is large, very easily produce leakage, cause erosion, due to for once step-down during unlatching, can not High Pressure Difference be born, thus generation cavitation phenomenon, cause vibrations, noisiness is large, and valve is easily bad.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, propose a kind of air-out tube valve, described exhaust steam valve can bear high temperature, high pressure and high pressure differential environment.
Technological scheme of the present invention is: a kind of air-out tube valve, comprises spool, valve seat and valve gap, and spool is arranged on valve seat inside, is provided with shrouds on the top of valve seat; Described valve gap is hollow, it is positioned at and shrouds top, a guide sleeve and a bonnet gasket is provided with at described valve gap and between shrouding, valve gap is tightened together by securing means with shrouding, a support is provided with above valve gap, be provided with locking nut on the bracket, between locking nut and spool, be connected with a valve rod.
Filler is provided with between described valve rod and valve gap.
Described support is tightened together with valve gap by screw.
The present invention has following beneficial effect:
1) Safety performance of the present invention is high, noise is little, it is little to shake, and meets the need of market.
2) the present invention adopts three telescopicly to shroud structure, can repeatedly step-down, plays good regulating action.
3) valve of the present invention adopts upper entering and lower leaving, does not crack time emptying.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Accompanying drawing is the main TV structure schematic diagram of the present invention.
In figure, 1, filler; 2, valve rod; 3, guide sleeve; 4, valve gap; 5, shroud; 6, locking nut; 7, hold-down grid; 8, support; 9, bonnet gasket; 10, valve seat; 11, spool.
Embodiment:
Shown in accompanying drawing, the present invention includes and comprise spool 11, valve seat 10 and valve gap 4, spool 11 is arranged on the inside of valve seat 10, is provided with shrouds 5 on the top of valve seat 10; Described valve gap 4 is hollow, it is positioned at the top shrouding 5, a guide sleeve 3 and a bonnet gasket 9 is provided with at described valve gap 4 and between shrouding 5, valve gap 4 with shroud 5 and tightened together by securing means, a support 8 is provided with above valve gap 4, described support 8 is provided with locking nut 6, a valve rod 2 is connected with between locking nut 6 and spool 11, the lower end of described valve rod 2 is screwed in the top of spool 11, the upper end of described valve rod 2, through after guide sleeve 3, is screwed together by the screw thread on valve rod 2 top and locking nut 6.In order to reduce vibrations, between described valve rod 2 and valve gap 4, be provided with filler 1.Described support 8 is tightened together with valve gap 4 by screw.Be provided with hold-down grid 7 on the top of filler 1, described hold-down grid 7 by bolt and support 8 fastening.The present invention adopts three telescopicly to shroud structure, can repeatedly step-down, and play good regulating action, during work, valve of the present invention adopts upper entering and lower leaving, does not crack, Safety performance of the present invention is high, noise is little, shakes little, meet the need of market time emptying.
