Description
The utility model relates to a kind of valve, particularly about a kind of heating installation locking valve.
China city dweller's heating at present, all be to adopt heating installation, and the valve that is provided with in heating pipeline all is general shutoff valve, this valve resident can random free opening and closing, are unfavorable for management, particularly in recent years, outstanding problem in the urban heat supplying is, heating fee is difficult to take over, and most of residents do not hand over the heating installation expense, and heating department can not selectively close the user who does not hand over the heating installation expense.The building that also has part newly to build up gives the phenomenon of the whole heating of entire building customary especially owing to only selling the part house, and this certainly will cause a large amount of energy wastes.
But the purpose of this utility model provides a kind of heater control valve of locking.
Technical solution of the present utility model is: a kind of heating installation locking valve, substantially be by spool 2 is housed in the valve body 1, and one end and spool 2 join, the other end is positioned at valve body 1 outer valve rod 4 and constitutes, between valve body 1 and the spool 2 seal ring 3 is housed, valve rod 4 is provided with sealing gasket 5 with valve body 1, and fastening piece 6 is housed on the sealing gasket 5.It is characterized in that: be provided with sheath 7 around the valve rod 4 outside valve body 1, sheath 7 upper ends are connected to protecting cover 8, and protecting cover 8 outer ends are connected to the helmet 10 that is connected with connecting pin 11 by spring ring 9.
The utility model compares with prior art that to have a locking safe and reliable, and the layman can't arbitrarily open, and is rational in infrastructure, easy to use, low cost and other advantages.
Accompanying drawing 1 is the utility model embodiment's a structural representation.
Below in conjunction with description of drawings embodiment:
Valve body 1 adopts cast iron to be processed into two-part, and a part one end wherein is processed with internal thread, and another part joins with it by screw thread, and is processed with internal thread in the end.Earlier the seal ring 3 of an end is loaded onto during installation, and then the spool 2 that will adopt copper to process is loaded onto, put into again in the other end connection of a seal ring 3 with valve body 1, load onto valve rod 4, sealing gasket 5 and fastening piece 6, sheath 7 and valve body 1 consubstantiality, in sheath 7, be processed with internal thread, helmet 10 adopts cast iron to process, relevant position on the sidewall of helmet 10 internal upper parts is processed with groove, protecting cover 8 helmet 10 internal upper parts of packing into, be processed with on protecting cover 8 outer walls with sheath 7 inwalls on the corresponding outside thread of internal thread, protecting cover 8 upper ends and helmet 10 upper bottom portion adopt connecting pin 11 to be connected, spring ring 9 is equipped with at the groove place on protecting cover lower edge, 8 upper end and helmet 10.When this valve uses, earlier valve rod 4 is screwed to the position closed and then helmet 10 is screwed on the sheath 7 by protecting cover 8, just connecting pin 11 is twisted into two parts after the locking, helmet 10 just twists not got off like this, thereby reach the purpose of locking, have only during unlatching helmet 10 usefulness special tools broken protecting cover 8 could being screwed down of folder exposed valve rod 4.
