Abstract
The utility model relates to a pressure and adjustable steam trap; a valve rod, a valve seat and an elastic heat-sensing deforming piece are arranged inside a valve cavity which consists of a valve body and a valve shell; a valve core sphere is arranged on the valve rod; a thread rod is arranged on the upper part of the valve rod; an adjusting nut and an adjusting seat are arranged on the thread rod; the upper end of the adjusting seat is provided with an adjusting pole and an adjusting piece; the below end of the adjusting piece is inserted inside the adjusting seat; the thread rod can be moved up or down corresponding to the adjusting nut. The utility model has the advantages that: the adjusting pole is arranged on the valve shell; so under the situation of opening the valve cavity for the valve pole and the valve core sphere, the pressure can be adjusted at any moment freely; besides, the adjustment is very convenient and saves the time and energy.
Description
Technical field
The utility model relates to a kind of valve, and is particularly a kind of with pressing adjustable Automatic steam trap Trap.
Background technique
Automatic steam trap Trap is a kind of valve of automatism, also is steam trap, is mainly used in to get rid of condensed water on steam heating equipment or the pipeline automatically, prevents steam leakage and loss.
This valve is a kind of valve open in usual under the normal temperature state, and be a kind of Normally closed type valve in hot operation state following time, according to the variation of condensed water in the valve pocket, open or close spool by the elasticity thermosensitive element, thereby in time automatically get rid of the condensed water in gas utilization unit and the steam pipe system.When steam enters valve pocket in the pipe network, under the elastic deformation force's of elasticity thermosensitive element effect, drive the spool throttle down.When producing certain water of condensation in the pipe network after work a period of time, thereby elasticity thermosensitive element resilience control valve spool reopens, the discharging condensed water.The throttle down that automatically resets again when condensed water discharging finishes with this back and forth " opening-close-open-close ", thereby plays the effect of timely discharging condensed water again again.The elasticity thermosensitive element changes according to variation of temperature in the valve control, thereby plays the effect of " opening-close-open again-close again ".
Automatic steam trap Trap is generally used for indirect heated component, and generally being boiler, the vapour source of heating plant directly send vapour or pipe network to send vapour, the normal condition downforce can be guaranteed in certain scope, but the range pressure fluctuation also can appear sometimes, will bring influence to the water displacement and the leakage vapour rate of Automatic steam trap Trap like this, at this moment, will adjust the valve core sealed cover of Automatic steam trap Trap.Moreover along with the time lengthening that uses, the sealing surface of spool also can produce certain wearing and tearing, and its sealing surface also will carry out suitable adjustment.
Present existing Automatic steam trap Trap does not have controlling device outside valve body, adjust seal spool, must open the valve control and just can adjust.Obviously, open valve pocket and must close the vapour source, pipeline quits work and just can adjust, and mostly situation next time property be difficult to adjust to the right place, need repeatedly to adjust repeatedly and on probationly just can reach requirement, obviously waste time and energy, influence work efficiency, debugging is very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of with pressing adjustable Automatic steam trap Trap, do not closing under the band pressure condition in vapour source, need not open valve pocket and can adjust the seal clearance of spool and sealing surface thereof in the outside of valve body, and regulate very convenient, time saving and energy saving.
Technical solution of the present utility model is, be provided with valve rod, valve seat and elasticity temperature-sensitive distortion sheet in the valve pocket that valve body and valve casing constitute, the lower end of valve rod is provided with the spool spheroid, connect for fork type is movable between elasticity temperature-sensitive distortion sheet and the valve rod, it is characterized in that: the upper end of valve rod is a threaded stem, its threaded stem is provided with adjusting nut and adjustment seat, and adjusting nut connects with threaded stem, and adjustment seat and valve rod are fixedly connected; The upper end of adjustment seat is provided with adjustable lever and adjustment sheet, and the lower end of adjustment sheet inserts in the groove of adjustment seat, and the upper end and the adjustable lever of adjustment sheet are fixedly connected; Adjustable lever is pressed on the valve casing by gland.
Groove on the adjustment seat is the flat groove of U-shaped.
The lower end of adjustment sheet and the flat groove bottom of the U-shaped of adjustment seat are provided with the gap.
The utility model and prior art compare, and the advantage that is possessed is that adjustable lever is located on the valve casing, and be exposed to the outside of valve casing, make the utility model under the state of not closing the vapour source, can be with pressure to transfer to other localities at any time, and regulate very convenient, time saving and energy saving in the valve body outside.
The drawing explanation
Accompanying drawing is a structural representation of the present utility model.
Number in the figure: 1-valve casing, 2-seal ring, 3-gland, 4-adjustable lever, 5-sealing gasket, 6-adjustment sheet, 7-adjustment seat, 8-Cock screw, 9-connecting plate, 10-adjusting nut, 11-valve rod, 12-valve seat, 13-spool spheroid, 14-valve body, 15-elasticity temperature-sensitive distortion sheet.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Present embodiment comprises valve body 14 and valve casing 1, in the valve pocket that valve body 14 and valve casing 1 constitute, be provided with valve rod 11, valve seat 12 and elasticity temperature-sensitive distortion sheet 15, the lower end of valve rod 11 is provided with spool spheroid 13, connects for the fork type activity between elasticity temperature-sensitive distortion sheet 15 and the valve rod 11.12 of spool spheroid 13 and valve seats constitute sealing surface.
The upper end of valve rod 11 is a threaded stem, and its threaded stem is provided with adjusting nut 10 and adjustment seat 7, adjusting nut 10 and valve rod 11 scyewed joint, and adjustment seat 7 is fixedly connected by Cock screw 8 with valve rod 11.The upper end of adjustment seat 7 is provided with adjustable lever 4 and adjustment sheet 6, and the lower end of adjustment sheet 6 inserts in the flat groove of U-shaped of adjustment seat 7, and the upper end of adjustment sheet 6 and adjustable lever 4 are connected to one.The flat groove bottom of the U-shaped of the lower end of adjustment sheet 6 and adjustment seat 7 is provided with certain stroke gap.
When the sealing surface gap that needs between regulating spool spheroid 13 and the valve seat 12, get final product with a screw-driver rotation adjustable lever 4.Its regulating method is: with screw-driver rotation adjustable lever 4, driving adjustment seat 7 by adjustment sheet 6 rotates, thereby driving valve rod 11 rotates, because of valve rod 11 is a scyewed joint with adjusting nut 10, adjusting nut 10 does not rotate under the connecting plate 9 on the elasticity temperature-sensitive distortion sheet 15 stops, so valve rod 11 moves up and down, thereby reach the desirable gap of regulating spool spheroid 13 and 12 sealing surfaces of valve seat in adjusting nut 10.
