For solving above-mentioned technical problem, this utility model realizes as follows: a kind of plough groove type setting gate valve of elasticity rising stem (RS.) of design, its by handwheel, bracing frame, location nut, valve rod, valve gap, valve body, valve plate, fixing bolt, let out dirty hole and form；The top of valve gap is bracing frame, and the two is structure as a whole；Support frame as described above is provided with valve stem nut, and described valve rod upper end is formed with locking nut and threadeds after sequentially passing through valve stem nut and handwheel；Handwheel and valve rod are fixed on bracing frame by described valve stem nut and locking nut jointly, and valve stem nut is formed with valve rod and threadeds；The lower end of valve rod, through the valve gap below bracing frame, enters the valve body below valve gap；Valve gap is fixedly connected with the valve body；Described valve inner is provided with valve plate, and valve plate is formed with valve rod and is flexibly connected；It is provided with in the position that valve body lower portion is corresponding with valve rod and lets out dirty hole；On described valve rod, bracing frame be additionally provided with location nut between the upper and lower ends.
Further, in order to the sealing property making gate valve is better, described valve gap and valve body junction are provided with O RunddichtringO.
Further, in order to blowdown is convenient, described in let out dirty hole downwardly projecting, and be provided with a circle external screw thread at its outer surface, letting out, sealing cap be installed outside dirty hole, and seal cap inner surface and be provided with the female thread coordinated with the external screw thread letting out dirty hole.
Further, in order to the sealing property of gate valve is better, described in let out dirty hole and seal and be provided with O RunddichtringO between cap.
Further, in order to allow the more specific position determining location nut of user, described location nut is outside is band coloured paint surface.
Further, in order to make valve body more durable, described valve body can adopt the one in magnesium iron, carbon steel.
Further, in order to make valve rod more durable, described valve rod adopts straight-chromiun stainless steel material.
Good effect of the present utility model: in technical solutions of the utility model, provide that a kind of elastic memory is good, long service life, not easily alluvial foreign material and sealing property are reliable, also has the plough groove type setting gate valve of elasticity rising stem (RS.) of the advantage that the duty of gate valve easily identifies simultaneously, the valve rod of the setting gate valve of this rising stem (RS.) is provided with location nut, user can see the duty of gate valve very intuitively, simultaneously it is connected with firth outlet hole at valve body, firth outlet hole can be opened when valve inner has deposited more dirt, get rid of dirt, it is ensured that the sealing of gate valve.
