Abstract

The utility model relates to a flow control valve and structure improvement, especially applicable as a regulating valve in sectors of air volume adjustment, smoke control & fire prevention. The utility model is intended to solve such current problems as welding of upper and lower vanes of a flow control valve and complex processing associated therewith, with respect to which a flow control valve with integral vanes (upper and lower) and simple processing is presented. The utility model comprises a frame (2), a sealing component (10) positioned inside (11) the frame (2), a controlling and regulating device (4) positioned outside (3) of the frame (2) and a connecting shaft (6) specific for a sleeve (5) via a main connecting rod (8), a slave connecting rod (9), and a crutch (7). The gist of the valve structure lies in vane (1) integrating upper and lower sub-vanes.

Description

A kind of flow control valve

Technical field:

The utility model relates to the improvement of flow control valve arrangement, is particularly useful for air quantity adjusting, Smoke proofing and fire proofing modulating valve field.

Background technique:

The blade of flow control valves such as existing air quantity adjusting, Smoke proofing and fire proofing adjusting adopts upper blade 16 and lower blade 15 to constitute usually.Because upper blade 16 need be welded with lower blade 15, therefore the junction point at upper blade 16 and lower blade 15 just leaves many scraggly solder joints 17, has influenced outward appearance; Because of the welding of upper blade 16, increased the time processing process again simultaneously, made operation loaded down with trivial details with lower blade 15; The more important thing is: the weld of upper blade 16 and lower blade 15 is easy to generate looseningly in transportation and installation process, makes upper blade 16 and lower blade 15 when the regulating and controlling flow, and swoosh is moving, thus the influence use.

The model utility content:

The utility model is exactly that the upper blade, the lower blade that solve present flow control valve need be welded, the problem of processed complex, and to have proposed a kind of upper blade, lower blade be one, process simple flow control valve.

The utility model adopts following technological scheme: the utility model comprises framework, the inboard of framework is provided with Sealing, the arranged outside of framework has controlled adjuster, controlled adjuster by master connecting rod, slave connecting rod, turn head and link to each other with the axle of axle sleeve, its structure outline is that blade is that upper blade and lower blade are and are wholely set.

The draw-in groove place of the blade head of blade is provided with the annular plug of movable connection.

The beneficial effects of the utility model:

1. processing is simple:

The utility model adopts a die sinking directly to be made of one piece, and has reduced the course of working of welding, therefore processes simply, is easy to promote, is easy to make;

2. the surface aesthetic of blade:

Because blade of the present utility model is that a die sinking directly is made of one piece, therefore just reduced the course of working of welding, also avoided the scraggly solder joint on the surface of the upper blade of blade and lower blade simultaneously, thereby made blade surface smooth, attractive in appearance;

Soundness good, can use for a long time:

Because blade of the present utility model adopts a die sinking directly to be made of one piece, so soundness is good, bring great convenience for simultaneously transportation and installation, be convenient to permanently effective use.

Fig. 2 is the left view of Fig. 1;

A when Fig. 3 is 45 ° of the blade rotation of Fig. 1 is to view;

Fig. 4 is the structural representation of blade of the present utility model;

Fig. 5 is the structural representation of existing upper blade, lower blade.

Embodiment:

The utility model comprises framework 2, the inboard 11 of framework 2 is provided with Sealing 10, the outside 3 of framework 2 is provided with controlled adjuster 4, controlled adjuster 4 by master connecting rod 8, slave connecting rod 9, turn 7 and link to each other with the axle 6 of axle sleeve 5, blade 1 is that upper blade and lower blade are and are wholely set.

When actual size is slightly larger than blade 1 overall length dimension, can be provided with the annular plug 14 of movable connection at draw-in groove 13 places of the blade head 12 of blade 1.

Claims

1. a flow control valve yoke (2), the inboard (11) of framework (2) is provided with Sealing (10), the outside (3) of framework (2) is provided with controlled adjuster (4), controlled adjuster (4) links to each other by master connecting rod (8), slave connecting rod (9), the axle (6) that turns head (7) and axle sleeve (5), it is characterized in that blade (1) is that upper blade and lower blade are and are wholely set.

2. a kind of flow control valve according to claim 1 is characterized in that locating to be provided with at the draw-in groove (13) of the blade head (12) of blade (1) the annular plug (14) of movable connection.
