Description
The utility model relates to a kind of valve, the particularly a kind of valve of locking closure and unlatching key of this valve of having.
The valve that uses in pipework at present has a variety of, more common a kind of valves to comprise valve body, is installed in the spherical valve core in the valve body, the valve rod that links together with spool; Valve body is a threeway shape, and a liquid entering hole, a liquid outlet and a valve rod mount inlet are arranged; Be shaped on circular groove on the valve rod, be provided with seal ring in the circular groove, the valve rod that has seal ring is inserted in the valve rod mount inlet of valve body, rotates spherical valve core by pulling valve rod during use, reaches the purpose of opening and closing valve; As time goes on, people have installed lockset on the valve of said structure, with lockset opening and closing valve; In use the valve of said structure has following shortcoming: 1. foreign matter stops up lockhole, and 2. available ten thousand is key operated, and 3. people can open with instruments such as spanners.
The purpose of this utility model is to overcome above-mentioned defective, provide a kind of easy to operate, encryption is strong, survivable pipeline locking valve and its are opened key.
For achieving the goal, the utility model adopts following technological scheme: the valve rod that this pipeline locking valve comprises valve body, be installed in spherical valve core in the valve body, link together with spool; Valve body is a threeway shape, and a liquid entering hole, a liquid outlet and a valve rod mount inlet are arranged; Be shaped on circular groove on the valve rod, be provided with seal ring in the circular groove, the valve rod that has seal ring is inserted in the valve rod mount inlet of valve body; The pipe shape of valve rod mount inlet on the valve body for protruding, outside the pipe shape valve rod mount inlet that protrudes, be with the interior cover of a ∏ shape with a gap, the top of valve rod is connected with the inside top of cover in the ∏ shape, be shaped on blind hole and hole on the same position radially of in pipe shape valve rod mount inlet that protrudes and ∏ shape, overlapping, pressure spring and permanent magnetism post are installed in blind hole and the hole successively; Have a central angle on the cross section of in ∏ shape, overlapping simultaneously and be 90 ° annular groove perpendicular to valve rod, on the pipe shape valve rod mount inlet sidewall that protrudes, with central angle is that the corresponding fixed-site of 90 ° of grooves has a pin, and this pin insertion central angle is in 90 ° the annular groove; The outer gapped ∏ shape overcoat that is with of cover in ∏ shape, ∏ shape overcoat is stuck in the ∏ shape in the annular groove on the cover outer side wall by pin, and concordant bottom being enclosed within ∏ shape overcoat and the ∏ shape; The lower bottom part edge that overlaps in ∏ shape overcoat and ∏ shape all is shaped on radially outer flange, and the axisymmetric same position of cover flange is shaped on two grooves that concave respectively in ∏ shape overcoat and ∏ shape.
The unlatching key of this pipeline locking valve comprises ring key body and the key bar that is connected on the ring key body, and is shaped on two projectioies of axially stretching out axisymmetrically at sidewall one end of ring key body, is embedded with the permanent magnetism post in the sidewall of ring key body; When putting outside the ring key body is enclosed within the pipeline locking valve, two of ring key body sidewall one end projectioies are inserted in the groove of cover same position in ∏ shape overcoat and the ∏ shape, and permanent magnetism post position is corresponding in above-mentioned permanent magnetism post and the pipeline locking valve, magnetic pole is identical.
The pipeline locking valve of employing said structure in use, the ring key body is enclosed within the outer of pipeline locking valve to put, two projectioies of ring key body sidewall one end are inserted in the groove of cover same position in ∏ shape overcoat and the ∏ shape, and, above-mentioned permanent magnetism post is corresponding with the permanent magnetism post position in the pipeline locking valve, and magnetic pole is identical; This moment, two permanent magnetism posts repelled mutually, permanent magnetism post in the pipeline locking valve is repelled in the blind hole of the pipe shape valve rod mount inlet sidewall of protrusion into, make the clip restriction that loses the permanent magnetism post between the pipe shape valve rod mount inlet of protrusion and the interior cover, thereby make the interior cover of ∏ shape in 90 ° of annular groove scopes, to rotate relative to the pipe shape valve rod mount inlet that protrudes, cover drives the valve rod rotation in the last ∏ shape, reaches the purpose of opening and closing valve.From the structure of the utility model pipeline locking valve, be embedded in the pipeline locking valve and key in the permanent magnetism post can have than multiposition, and burial place can't see from appearance, encryption is strong; Do not have the problem of opening with instruments such as spanners, this pipeline locking valve does not have lockhole again, does not exist to stop up lockhole and with the problem of unlocked by universal key.
Below by drawings and Examples the utility model pipeline locking valve is described further:
Fig. 1 is the sectional structure schematic representation of the utility model pipeline locking valve
Fig. 2 is the A-A sectional view of pipeline locking valve shown in Figure 1
Fig. 3 is the B-B sectional view of pipeline locking valve shown in Figure 1
Fig. 4 is the sectional structure schematic representation of pipeline locking opening of valves key shown in Figure 1
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the valve rod 6 that this pipeline locking valve comprises valve body 12, be installed in spherical valve core 11 in the valve body 12, link together with spool 11; Valve body 12 is threeway shape, and a liquid entering hole 20, a liquid outlet 21 and a valve rod mount inlet 7 are arranged; Be shaped on circular groove on the valve rod 6, be provided with seal ring 9 in the circular groove, the valve rod 6 that has seal ring 9 is inserted in the valve rod mount inlet 7 of valve body 12; The pipe shape of valve rod mount inlet 7 on the valve body 12 for protruding, outside the pipe shape valve rod mount inlet 7 that protrudes, be with the interior cover 2 of a ∏ shape with a gap, the top of valve rod 6 is connected with the inside top clip of cover 2 in the ∏ shape, in pipe shape valve rod mount inlet 7 that protrudes and ∏ shape, be shaped on blind hole and hole on the same position radially of cover 2, pressure spring 8 and permanent magnetism post 5 are installed in blind hole and the hole successively; In ∏ shape, have simultaneously a central angle on the cross section of cover 2 and be 90 ° annular groove 30 perpendicular to valve rod 6, on pipe shape valve rod mount inlet 7 sidewalls that protrude, with central angle is that the corresponding fixed-site of 90 ° of annular grooves 30 has a pin 4, and these pin 4 insertion central angles are in 90 ° the annular groove 30; The cover 2 outer gapped ∏ shape overcoats 1 that are with in ∏ shape, ∏ shape overcoat 1 is stuck in the ∏ shape in the annular groove 10 on cover 2 outer side walls by pin 3 is sliding, and ∏ shape overcoat 1 and ∏ shape interior overlap 2 concordant in the bottom; The lower bottom part edge of cover 2 all is shaped on radially outer flange in ∏ shape overcoat 1 and ∏ shape, and the axisymmetric same position of cover 2 base flange is shaped on two grooves that concave 31,32 respectively in ∏ shape overcoat 1 and ∏ shape.
