Abstract
The utility model relates to a filtering corrugated pipe type drain valve which comprises an inlet joint (1) and an outlet joint (2). The inlet joint (1) and the outlet joint (2) are communicated in a perpendicular mode. A branch pipe (3) and a corrugated pipe type drain valve body (4) are arranged between the inlet joint and the outlet joint in sequence. The filtering corrugated pipe type drain valve is characterized in that the branch pipe is directly arranged at the bottom of an inlet valve body in an inclined mode, an included angle formed between the branch pipe and the outlet joint is in the range of 30 degrees to 60 degrees, and the structure is compact. A filter screen in the branch pipe is arranged in an inlet valve body channel, can effectively filter impurities, and facilitates cleaning of the impurities, the corrugated pipe type drain valve body is prevented from pollution and blocking, thus, reliability of steam blocking drainage is improved, and the service life is prolonged. An outlet is connected by the adoption of a movable joint, only a joint nut needs to be screwed in a closed system threaded connecting pipeline, and disassembly and assembly can be convenient. The filtering corrugated pipe type drain valve combines the function of a filter, the function of the corrugated pipe type drain valve body and the function of the movable joint into a whole, is small and exquisite in size, attractive in appearance, small in fluid resistance, large in amount of drainage and small in probability of leakage, saves time and space of installation, is low in cost and long in service life, and is widely applied to steam blocking drainage in a steam pipe system.
Description
Technical field
The utility model relates to a kind of pipeline valve, is specifically related to a kind of filtration bellow type drain valve.
Background technique
The function of drain valve is the condensed water that can get rid of automatically in steaming plant or the steam conveying pipe, can stop steam to spill again, so claim steam trap again.The thermal expansion type drain valve is the temperature difference of utilizing steam and condensed water, makes the expansion element action, drives flap and opens automatically or close, to reach the purpose of block steam and drain water.The thermal expansion type drain valve mainly contains double-metal sheet type and bellow type.The heat-swelling element of bellow type drain valve is the copper bellows of sealing, the expansive liquid of interior dressing.When collecting condensed water in the valve body, because temperature is lower, the pressure in the bellows is reduced, so bellows contract, the drive flap rises and lifts off a seat, and makes the condensed water discharge.Treat the condensed water emptying and during steam leakage, because the temperature of steam is higher, the liquid evaporation swelling pressure in the bellows are increased, descend so drive spool, valve passage is closed.Along with the prolongation of time, the impurity that contains in vapour, the water can accumulate on valve opening or the 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 be equipped with the filter impurity screening.Drain valve is installed on steaming plant or the pipeline minimum point waste pipe usually, and front and back arrange the cut-off valve easy access, and the drain valve that is threaded should be equipped with union and be convenient to dismounting.The condensed water of getting rid of is if enter house steward, and for preventing that condensed water flows backwards in the pipe network, the drain valve outlet should be equipped with safety check.Drain valve group parts are many like this, and it is big to take up room, and the installation time is long, the expense height, and steam seepage probability is big.
Therefore, for solving the problems of the technologies described above, be necessary to cooperate the bellow type drain valve, at entrance point filtrating equipment be set, outlet end arranges union, and filter, drain valve, union function are concentrated on one, and effectively conserve space and cost prolong life of valve.
The model utility content
The purpose of this utility model is to provide a kind of to be had filtration and can be used for the be threaded filtration bellow type drain valve of pipeline of locking system.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of filtration bellow type drain valve, the inlet union (1) that comprises vertical connection, outlet connection (2) is disposed with arm (3) and bellow type drain valve (4) between the described import and export joint, it is characterized in that being provided with filter screen in the entrance point arm, effective impurity screening, drain valve can be not contaminated and be stopped up, and is reliability and durability, and outlet connection is set to union and connects and be convenient to dismounting.
Filtration bellow type drain valve of the present utility model, described inlet union (1) is provided with internal thread; Outlet connection (2) is provided with outside thread, and by nut the external piece that has internal thread is connected with valve body.
Described arm (3) is downward-sloping to be arranged on import valve body bottom, and the outlet connection angle is between 30 °-60 °.The built-in filter screen of arm (5), filter screen is positioned at the import valve channel.The arm bottom is provided with end cap (6).Be provided with seal ring (7) between described end cap and the arm.During the preposition valve closing of drain valve, open that a pipe end-cap is desirable to go out filter screen cleaning impurity.
Compared with prior art, the utlity model has following characteristics and beneficial effect: described arm directly is obliquely installed at import valve body bottom, compact structure.Filter screen is positioned at the import valve channel in the arm, can effectively filter and easy cleaning impurity, drain valve is exempted from pollute and obstruction, thereby improve the block steam and drain water reliability, increases the service life.Outlet adopts union to connect, and only the swivel joint nut is just conveniently detachable in locking system is threaded pipeline.This valve collection filter, bellow type drain valve and union function are one, and volume is small and exquisite, and is aesthetic in appearance, and fluid resistance is little, and water displacement is big, and the seepage probability is little, save installation time and space, and cost is low, and the life-span is long, is widely used in block steam and drain water in the steam pipe system.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
With reference to Figure of description 1, the utility model embodiment further describe into:
A kind of filtration bellow type drain valve is arranged at described arm (3) and bellow type drain valve (4) between inlet union (1) and the outlet connection (2).Described inlet union has internal thread, and outlet connection is set to union.Filter screen (5) is packed in the arm (3), and filter screen is positioned at the import valve channel just, effectively impurity screening.Seal with screwed joint is adopted with end cap (6) and seal ring (7) in the arm bottom.When the preposition valve closing of drain valve, open that pipe end-cap is desirable to be gone out filter screen cleaning impurity or change filter screen.
Claims (3)
1. one kind is filtered the bellow type drain valve, the inlet union (1) that comprises vertical connection, outlet connection (2), be disposed with arm (3) and Impulse steam trap (4) between the described inlet/outlet joint, it is characterized in that being provided with filter screen in the entrance point arm, and outlet connection is set to the union connection.
2. filtration bellow type drain valve as claimed in claim 1, it is characterized in that: described inlet union (1) is provided with internal thread; Outlet connection (2) is provided with outside thread, and by nut the external piece that has internal thread is connected with valve body.
