As shown in Figure 1, control valve 10 has a valve body 16 (when control valve of the present invention is that this valve body 16 has circular cross-section when being connected in the tubular shape pipeline), also has one and is used to be provided with the chamber 17 that limits screw 15.Turnover panel 13 (referring to Fig. 3 following) has a lug 18, and an end of spring 14 (Fig. 3) connects (the other end of spring 14 is fixed on the projection 19, please referring to Fig. 3) thereon.Turnover panel 13 has hinged ear 20,21 (Fig. 2), is used for the articulated elements 22,23 that (coaxially) is hinged on articulated slab 24.

(turnover panel 13 and articulated slab 24 are illustrated separately) as shown in Figure 2 has outwardly directed hinge pin on the articulated

elements

25,26 on the articulated slab 24, is used for respectively matching with pit on the hinged ear 21,20.Articulated slab 24 and turnover panel 13 can be made as two independent parts, simultaneously articulated slab 24 can be stuck in or be pressed in the respective slot in the valve body 16 of control valve 10 or adhere in the valve body 16, thereby turnover panel 13 is hingedly fixed in the valve body 16 rightly, and can digs from panel seat 48 pivots that are formed on the valve body 16.

As shown in Figure 3, control valve body 16 has a socket end 27 and a plug end 28, and these ends guarantee that control valve body 16 can at one end be connected with corresponding pipeline, and an other end is connected with the pipe clamp (see figure 4).Be perfectly clear, this plug-socket formula Placement also can be used conversely.Spring 14 is in extended state as shown in the figure between lug 18 and the projection 19 in the inboard in the hole of valve body 16, the edge 49 of turnover panel 13 is against on the valve seat 48.In the ordinary course of things, turnover panel 13 is controlled to opening state by spring 14.The opening degree of turnover panel 13 depends on the position that limits screw 15.The articulated elements 20 of turnover panel 13 has an inclined-plane 29, and this inclined-plane 29 is used for when turnover panel 13 is opened under the pulling of spring 14, cooperates with qualification screw 15.The opening angle of turnover panel 13 limits by the cooperation of the end of inclined-plane 29 and qualification screw 15.To limit screw 15 and inwardly twist, the opening angle of turnover panel 13 is reduced.
