Further, described handwheel, valve rod are fixedly connected with by screw thread successively with spool.
Further, described lower handwheel, lower valve rod and lower valve core are fixedly connected by welding successively.
Further, the threaded upper end of described valve rod is provided with baffle plate, and described valve gap is also provided with jack, and the jack on described valve gap is fixedly connected with described baffle plate by pin.
Further, the quantity of described stationary platen is two, and the upper surface of described lower valve core is greater than the cavity between described two stationary platens.
Further, between described spool and described valve gap, be provided with sealing gasket, between described lower valve core and described valve body, be provided with lower seal pad.
The advantage that the utility model has and good effect are:
1, the valve in the utility model adopts multi-part to be fixed connection by screw thread or fastening piece, achieves the target that all parts is changed separately; Have additional the lower valve core, lower valve rod and the assistant's wheel component that are welded to connect in this valve and have structure simply, antiwear property is strong, serves the effect of damming of auxiliary-valve in prior art on the one hand, makes valve mechanism more perfect, cost-saving on the other hand.
2, valve of the present utility model has valve gap, cover plate and pin simultaneously, achieves when changing valve part and optionally dismantles valve, do not affect the work of miscellaneous part.
3, the valve in the utility model is also provided with upper and lower sealing gasket on vibrational power flow, ensure that the normal use of valve; Valve has the features such as structure is simple, for convenience detach and safe and reliable.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is illustrated:
As shown in Figure 1, a kind of valve for convenience detach, comprise valve body 1, valve gap 2, valve rod 4, spool 7, handwheel 8 and the valve seat 9 being positioned at described valve body 1 inside, the top of described valve body 1 is provided with mounting platform 10, the inside of described valve body 1 is provided with stationary platen 15, described stationary platen 15 is positioned at the below of described valve seat 9, the mounting platform 10 of described valve body 1 is fixedly connected with described valve gap 2 by bolt, the top of described valve gap 2 is provided with cover plate 3, described valve gap 2 is fixedly connected with described cover plate 3 by bolt, described valve rod 4 is flexibly connected with described valve gap 2 by screw thread, the top of described valve rod 4 is flexibly connected with described handwheel 8, the bottom of described valve rod 4 is flexibly connected with described spool 7, the below of described valve body 1 is also provided with the lower valve core 11 connected successively, lower valve rod 12 and lower handwheel 13, described lower valve core 11 is positioned at the below of described stationary platen 15.
Described handwheel 8, valve rod 4 are fixedly connected with by screw thread successively with spool 7.Described lower handwheel 13, lower valve rod 12 are fixedly connected by welding successively with lower valve core 11.
The threaded upper end of described valve rod 4 is provided with baffle plate 16, and described valve gap 2 is also provided with jack, and the jack on described valve gap 2 is fixedly connected with described baffle plate 16 by pin 6.
