Flap drive unit, described flap drive unit drive described flap and do up and down and to move, and insert or break away from the described valve seat;
Form plural patchhole on the described valve seat, the relevant position of described flap is provided with similar number, is fit to insert the insertion rod different in size in the corresponding described patchhole.
Described throttle valve, also form suitable described flap on the described valve body and stretch into the interior insertion mouth of described inner chamber, described insertion mouth is provided with valve gap, moulding is fit to the through hole that described flap drive unit passes on the described valve gap, the top of described through hole is provided with internal thread, described flap drive unit is an end and inserts in the described flap, be connected with described flap rotationally, and drive described flap and move up and down, the other end is provided with the valve shaft of handwheel, form outside thread on the relevant position of described valve shaft with described screw-internal thread fit, and described outside thread is provided with the flow mark line identical with described insertion rod radical, and the distance between the adjacent two described flow mark lines equals the length difference of two corresponding described insertion rods.
Described patchhole is provided with three that area does not wait, and described insertion rod is provided with three, and described flow mark line is provided with three.
Described throttle valve, the inwall of described patchhole is provided with seal ring.
Technique scheme of the present utility model has the following advantages compared to existing technology, 1, in the utility model, form plural patchhole on the valve seat, the relevant position of flap is provided with similar number, be fit to insert the insertion rod different in size in the corresponding patchhole, can realize the adjusting of multiple numerical value flow, and regulate flow at every turn that the area of the patchhole by not being inserted with insertion rod and number decide the numerical value of the flow after the adjusting; 2, in the utility model, the setting of flow mark line can make things convenient for the flow that the throttle valve user accesses very soon to be needed on the valve shaft.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the schematic representation of throttle valve of the present utility model.
Reference character is expressed as among the figure: 1-valve body, 2-water intake, 3-water outlet, 4-valve seat, 5-flap, 6-patchhole, 7-insertion rod, 8-valve gap, 9-valve shaft, 10-flow mark line, 11-seal ring, 12-handwheel.
Embodiment
As shown in Figure 1, a kind of throttle valve of embodiment 1 comprises valve body 1, flap 5, and the flap drive unit forms inner chamber in the wherein said valve body 1, is provided with the valve seat 4 that the water intake 2 of described valve body 1 and water outlet 3 are separated in the described inner chamber; Described flap 5 is suitable for inserting in the described valve seat 4, stops the water section at described water intake 2 places or all flows to described water outlet 3; Described flap drive unit drives described flap 5 and does up and down and to move, and inserts or breaks away from the described valve seat 4; Form plural patchhole 6 on the described valve seat 4, the relevant position of described flap 5 is provided with similar number, be fit to insert the insertion rod different in size 7 in the corresponding described patchhole 6, can realize the adjusting of multiple numerical value flow, and regulate flow, the area of the described patchhole 6 by not being inserted with described insertion rod 7 and number decide the numerical value of the flow after the adjusting at every turn.In the present embodiment, described patchhole 6 is provided with three that area does not wait, and described insertion rod 7 is provided with three, when rotating described valve shaft 9, thereby when driving in the described patchhole 6 on the described valve seat 4 of the longest described insertion rod 7 elder generations insertion on the described flap 5, be first flow; Continuing the described valve shaft 9 of rotation, when the described insertion rod 7 of the vice-minister on the described flap 5 is also inserted in the described patchhole 6 on the described valve seat 4, is second flow; At last, when the shortest described insertion rod 7 is inserted in the described patchhole 6 on the described valve seat 4 again on the described flap 5, be whole throttlings.
