Abstract
The utility model relates to a pipeline valve, and specifically relates to and discloses an automatic evacuation heat power dewatering valve. The automatic evacuation heat power dewatering valve comprises a valve body (1), a valve base (2), a valve block (3) and a valve cover (4), and the automatic evacuation heat power dewatering valve is characterized in that a permanent magnet alloy is inlaid on the eccentric position of the valve cover; when the gas supply in a pipe net is stopped, the pressure is reduced, and after the dewatering valve stops operating, the valve block rises so as to leave from the valve base under the magnetic force attraction of the permanent magnet alloy, and condensate water left in the dewatering valve is automatically evacuated; a filter is directly arranged on the bottom of the valve body in an inclined manner, and the structure is compact, a filter screen in the filter is positioned in an inlet valve body channel, the filter can effectively filter and conveniently clean impurities, the dewatering valve is free from pollution and blocking, the steam blocking drainage reliability is improved, and the service life is prolonged; the valve has an automatic evacuation function, the volume is small, the appearance is beautiful, the hydraulic resistance is small, the drainage flow is large, the drainage is in time, the leakage probability is small, the installation time and space are saved, the construction cost is low, the service life is long, and the automatic evacuation heat power dewatering valve is widely applied to block steam, drain and evacuation in steam equipment and the pipe net.
Description
Technical field
The utility model relates to a kind of pipeline valve, is specifically related to a kind of automatic-discharging thermodynamic trap.
Background technique
The function of drain valve is automatically to get rid of the condensed water in steaming plant or steam conveying pipe, can stop steam leakage again, therefore claim again steam trap.Thermodynamic trap is most widely used at present, and it is the different block steam and drain water purposes that reach of Thermodynamic Criteria of utilizing steam and condensed water.After condensed water enters valve body, static pressure is large, and valve block is held up and lifts off a seat, and drainage channel is opened, and condensed water is got rid of.When steam enters drain valve, because the steam static pressure acted on below valve block is little, steam can be scurried into the valve block upper space again because viscosity is little, make control room pressure above valve block raise, valve block falls rapidly and is stuck on the valve seat circular groove, closes drainage channel, stops steam to spill.But while stopping the reduction of air feed build-up of pressure in pipe network, drain valve will quit work, and the condensed water remained in drain valve just can't be discharged.In addition, along with the prolongation of time, the impurity contained in vapour, water can be gathered on valve opening or valve seat, causes internals pollution effect life-span, valve opening obstruction impeded drainage or valve to fit badly and leaked steam, so the drain valve entrance point should have filtrating equipment.Drain valve is arranged on steaming plant or pipeline minimum point waste pipe usually, and front and back arrange the cut-off valve easy access, and the drain valve be threaded also should be equipped with union and be convenient to dismounting.If the condensed water of getting rid of enters house steward, for preventing that in pipe network, condensed water flows backwards, loaded check valve is also answered in the drain valve outlet.Drain valve group parts are many like this, take up room large, and the installation time is long, and expense is high, and steam seepage probability is large.
Therefore, for solving the problems of the technologies described above, in conjunction with the structural feature of drain valve, be necessary magnet is set on valve gap, make drain valve that the automatic-discharging function be arranged after stopping the supple of gas or steam.And at valve inlet channel setting filtrating equipment, guarantee that valve is not polluted by granule foreign and stops up, effectively conserve space and cost, extend life of valve.
The model utility content
The purpose of this utility model is to provide a kind of thermodynamic trap that has the automatic-discharging function itself.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of automatic-discharging thermodynamic trap comprises valve body (1), valve seat (2), valve block (3), valve gap (4), is characterized in that on valve gap inlaying a permanent magnetic alloy, and the valve body bottom is provided with filter, existing automatic-discharging function, effective impurity screening again, drain valve can be not contaminated and be stopped up, reliability and durability.
Automatic-discharging thermodynamic trap of the present utility model, described valve body (1) two ends, left and right are provided with inlet-outlet connector (5), and bottom is provided with filter (6).
Described filter (6) is downward-sloping is arranged on the valve body bottom, and the outlet connection angle is between 40 °-50 °, is the Y type.The built-in filter screen of filter (7), filter screen is positioned at the import valve channel.Filter bottom end is provided with end cap (8).When the drain valve front valve is closed, open that end cap is desirable goes out filter screen cleaning impurity.
Described valve seat (2) is placed in valve body, and upper end is provided with circular groove (9), and circular groove is communicated with outlet connection.
Described valve block (3) is set to discoid, is placed on valve seat, and lifting flexibly in the control room (10) formed at valve seat (2) and valve gap (4).
Inlay a permanent magnetic alloy (11) on described valve gap (4) eccentric position, stop supply gas pressure and reduce in pipe network, after drain valve quits work, under the permanent magnetic alloy magnetic attraction, valve block rises and lifts off a seat, and remains in the condensed water automatic-discharging in drain valve.
Compared with prior art, the utlity model has following features and beneficial effect: inlay a permanent magnetic alloy on described valve gap eccentric position, stopping supply gas pressure in pipe network reduces, after drain valve quits work, under the permanent magnetic alloy magnetic attraction, valve block rises and lifts off a seat, and remains in the condensed water automatic-discharging in drain valve.And described filter directly is inclined at valve body bottom, compact structure.In filter, filter screen is positioned at the import valve channel, can effectively filter and easy cleaning impurity, drain valve is exempted from and pollute and stop up, thereby improve the block steam and drain water reliability, increases the service life.This valve has the automatic-discharging function, and volume is small and exquisite, aesthetic in appearance, and fluid resistance is little, and drain discharge is large, and draining is timely, and the seepage probability is little, saves installation time and space, and cost is low, and the life-span is long, is widely used in steaming plant and pipe network and hinders vapour, draining, emptying.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
