Abstract
The utility model relates to a filter impulse -type trap, especially relates to and discloses a filter impulse -type trap. The filter impulse -type trap comprises an inlet joint (1), an outlet joint (2), branch pipes (3) which are sequentially arranged between the inlet joint and the outlet joint, and an impulse -type trap. The filter impulse -type trap is characterized in that the branch pipes are arranged on the bottom of the inlet valve body in an inclination mode, the branch pipes are connected with the outlet joint in a clamping mode and has an intersection angle of 30 degrees to 60 degrees, and the structure of the intersection angle is compact. A filter net is positioned on the inlet valve body passageway and has the advantages of filtering impurities and enabling users to clean impurities conveniently, and the trap is avoided being polluted and blocked, thereby improving reliability and prolonging the service life of the vapor barrier drainage. The filter impulse -type trap combines the function of a filter, the function of an impulse -type trap and the function of a movable joint into a whole. Besides, the filter impulse -type trap has the advantages of being small and exquisite in volume, beautiful in appearance, low in hydraulic resistance, large in drainage flow and little in probability of leakage, and therefore time and space are saved. Meanwhile, the filter impulse -type trap further has the advantages of being low in manufacturing costs and long in service life, and therefore the filter impulse -type trap is widely used for vapor barrier 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 filtered pulse formula drain valve.
Background technique
The function of drain valve is the condensed water that can automatically get rid of in steaming plant or the steam conveying pipe, can stop again steam to spill, therefore claim again steam trap.The pulsed STEAM TRAP is to utilize the different block steam and drain water purposes that reach of Thermodynamic Criteria of steam and condensed water.After condensed water entered valve body, static pressure was large, spool can be held up to lift off a seat, and drainage channel is opened, and condensed water is got rid of.When steam entered drain valve, because the steam static pressure that acts on below the spool is little, steam can be scurried into the spool upper space again because viscosity is little, so that control room pressure raises above the spool, spool falls rapidly and is stuck on the valve seat, and the throttle down passage stops steam to spill.Along with the prolongation of time, the impurity that contains in vapour, the water can be gathered 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.If the condensed water of getting rid of enters house steward, 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, 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, be necessary to cooperate Impulse steam trap, at entrance point filtrating equipment be set, outlet end arranges union, and filter, drain valve, union function are concentrated on one, effective conserve space and cost, life-saving.
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 filtered pulse formula 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 filtered pulse formula drain valve, comprise the inlet union (1) that straight line is communicated with, outlet connection (2) is disposed with arm (3) and Impulse steam trap (4) between the described inlet-outlet connector, 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.
Filtered pulse formula 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 with 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.When the drain valve front valve is closed, open that pipe end-cap is desirable to go out filter screen cleaning impurity.
Compared with prior art, the utlity model has following features and beneficial effect: described arm directly is inclined 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 integrates filter, Impulse steam trap and union function, and volume is small and exquisite, and is aesthetic in appearance, and fluid resistance is little, and drain discharge is large, 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 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 filtered pulse formula drain valve is arranged at described arm (3) and Impulse steam trap (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 drain valve front valve is closed, open that pipe end-cap is desirable to be gone out filter screen cleaning impurity or change filter screen.
Claims (3)
1. filtered pulse formula drain valve, comprise the inlet union (1) that straight line is communicated with, outlet connection (2), be disposed with arm (3) and Impulse steam trap (4) between the described inlet-outlet connector, 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. filtered pulse formula 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 with internal thread is connected with valve body.
