Abstract

The utility model provides a slide throttle structure of a knife switch. A vertical slide groove and the other radial throttle channel are built in a valve body, wherein the vertical slide groove and the radial throttle channel are communicated. A knife switch type air blocking plate is arranged in a slide mode in the slide groove, an air-tight rubber pad is arranged on the air blocking plate, a stroke hole is arranged on the valve body and can be penetrated by a deflector rod, and the deflector rod is locked on the air blocking plate. Therefore, operators can easily operate the deflector rod to control the opening of the throttle channel, when the throttle channel is closed, the air blocking plate can provide better air tightness to block bidirectional air current in the throttle channel.

Description

Sliding type plug-in strip throttle structure

Technical field

The utility model relates to a kind of guillotine type throttle structure, particularly is provided with in valve body and can controls the plug-in strip form choke plate of air door passage open amount easily, and can effectively intercept the sliding type plug-in strip throttle structure of the two-way airflow in the air door passage when closing.

Background technique

Throttle structure is one to be widely used in the control member of air-conditioning, smoke evacuation and the water conservancy diversion of building or factory; As shown in Figure 1 more common, it is construction goes out to be connected in a valve body 10 chute 110 and another air door passage 120, and these air door passage 120 bilateral ends are connected with two airducts 40 respectively; Be slidingly equipped with a choke plate 20 in this chute 110, this choke plate 20 be can by by and chute 110 between friction, and be positioned arbitrary position in the chute 110, to adjust or to intercept the two-way airflow in the airduct 40.

Yet this kind group mode because choke plate is long-term and chute rubs and cause both losses, causes choke plate easily to cause loosening and landing voluntarily, thereby can't effectively adjust the two-way airflow in the airduct easily on the implementation; In addition, above-mentioned choke plate group mode is the airtight effect of tool not also, and it is desirable not to the utmost to cause this air door to intercept the effect of air-flow.

Summary of the invention

The purpose of this utility model is the defective that overcomes above-mentioned prior art, and a kind of guillotine type throttle structure is provided, and it is that a plug-in strip form choke plate is set in valve body, can effectively be positioned in the chute, and have airtight effect when closing air door.

The purpose of this utility model realizes by following technical proposals, sliding type plug-in strip throttle structure provided by the utility model, it is radially air door passage of construction goes out to be connected in a valve body a vertical chute and another, be slidingly equipped with the choke plate of a plug-in strip form in this chute, and this valve body is provided with the one stroke hole, and lock is organized on choke plate for a driving lever stretches through; In view of the above, but operator's easy operation driving lever with the open amount of control air door passage.

In addition, choke plate is provided with airtight rubber cushion, and when desiring to close the air door passage, airtight rubber cushion can provide preferable tightness, to intercept the two-way airflow in the air door passage.

For understanding structural feature of the present utility model and effect more, also in conjunction with the accompanying drawings it is carried out further detailed description below by embodiment.

Primary clustering symbol description: 1,10 valve bodies; 11,110 chutes; 12,120 air door passages; 121 air doors; 13 valve pipes; 131,43 flanges; 14 stroke holes; 2,20 choke plates; 21 airtight rubber cushions; 22 screws; 3 driving levers; 31 packing rings; 32 bolts; 40 airducts; 41 first airducts; 42 second airducts.

Embodiment

At first referring to shown in Figure 2, it is the three-dimensional exploded view of the utility model guillotine type throttle structure, its vertical chute 11 that mainly is that construction goes out to be connected in a valve body 1 and another air door passage 12 radially, and in this chute 11, be slidingly equipped with the choke plate 2 of a plug-in strip form; Wherein,

This air door passage 12 is the both ends of the surface of passing valve body 1, and on the both ends of the surface of valve body 1, form an air door 121 respectively, and these air doors 121 are connected with a valve pipe 13 respectively, and an end of this valve pipe 13 is provided with flange 131, again with bilateral flange 131 respectively lock organize on the flange 43 of first airduct 41 and second airduct 42 (as shown in Figure 3); This choke plate 2 is provided with airtight rubber cushion 21, in order to blocking the air-flow from first airduct 41 or second airduct 42, and is provided with a screw 22 on this choke plate 2 in addition; This valve body 1 is provided with one stroke hole 14 to guide a driving lever 3, one end of this driving lever 3 has a bolt 32, this bolt 32 is arranged with a packing ring 31, and this driving lever 3 is lock onto on the end face of valve body 1, and this bolt 32 can stretch through stroke hole 14 and lock is organized in the screw 22 of choke plate 2; In view of the above, can unscrew driving lever 3 and in chute 11, back and forth pass, and can effectively locate choke plate 2 by screwing driving lever 3 to drive choke plate 2.

When the air communication of desiring to make maximum flow is crossed air door passage 12 (as shown in Figure 3), the operator is by rotating driving lever 3 to unscrew bolt 32, and to pressing to 14 bottoms, stroke hole, rotate driving lever 3 again to screw bolt 32, and this choke plate 2 is located, cause this first airduct 41 to be connected, to obtain maximum throughput with the air-flow of second airduct 42; Change when the throughput of air door passage 12 is passed through in the desire adjustment (as shown in Figure 4), the operator only need rotate driving lever 3 conveniently to unscrew bolt 32, and upwards be pushed into 14 middle parts, stroke hole, with drive choke plate 2 in chute 11 inter-syncs to top offset, rotate driving lever 3 again to screw bolt 32, and make this choke plate 2 location, cause the air-flow of this first airduct 41 and second airduct 42 can be subjected to the effect of damming of choke plate 2, and obtain reducing the effect of throughput; In addition when desiring to close air door channel 12 (as shown in Figure 5), the operator also can control driving lever 3 in this way to close air door passage 12, and the airtight rubber cushion 21 that causes the air-flow of this first airduct 41 and second airduct 42 can be subjected on the choke plate 2 blocks; During this time, utilize to screw driving lever 3 and can effectively prevent choke plate 2 landings, therefore can control the throughput by air door passage 12 and close air door passage 12.

Comprehensive above-mentioned explanation believe that disclosing the utility model in detail can supply the usability of enforcement, and above-mentioned accompanying drawing that discloses and explanation only is embodiment of the present utility model, and be non-for limiting embodiment of the present utility model; All personages who is familiar with this skill, it complies with feature category of the present utility model, and other equivalence of being done changes or modifies, and all should be encompassed in the claimed claim of following the application.
