Abstract
The utility model belongs to the technical field of valves, particularly relating to a lifting valve used for normally open operating status. The utility model is mainly composed of a cylinder, a valve rod, a limiting baffle plate of the valve rod, a valve holder, a valve rod seal, a valve plate, a valve seat seal, a valve seat, etc. A fixed pulley is arranged on the valve holder. One end of a lifting rope is fixed on the valve rod. The other end of the lifting rope rounds the fixed pulley and is connected with counterweight. The utility model has the advantages of low cost, safety, simple structure and convenient operation and maintenance, which can be widely used for occasions which need normally open valves in industries of metallurgy, chemical engineering, energy, machinery, etc.
Description
The utility model belongs to valve technology field, relates in particular to a kind of poppet valve of the state of doing that is used for often going into operation.
The poppet valve of the existing state of doing that is used for often going into operation mainly is made up of cylinder, valve rod, valve rod postive stop baffle, vavle shelf, valve rod sealing member, valve plate, valve base seal, valve seat etc.This valve need to apply to the normally open of valve plate lifting.The deficiency of its existence is: this valve need keep uninterrupted and more stable source of the gas, keeps the cylinder of Pneumatic actuator that valve plate is upwards promoted, and the bleed pressure of Pneumatic actuator never can lose or fluctuate excessive, otherwise valve closes automatically, influences proper functioning.
It is a kind of simple and reasonable that the purpose of this utility model is to provide, the poppet valve that not influenced by source of the gas during proper functioning.
The purpose of this utility model realizes as follows: poppet valve, mainly form by cylinder, valve rod, valve rod postive stop baffle, vavle shelf, valve rod sealing member, valve plate, valve base seal, valve seat etc., static pulley is installed on vavle shelf, lifting rope one end is fixed on the valve rod, and the lifting rope the other end static pulley of having mercy on links to each other with counterweight.Its working procedure is: the valve plate that counterweight will link to each other with valve rod by lifting rope rises to often to go into operation makes state, and when the needs throttle down, cylinder moves downward and promotes valve rod and valve plate, with valve closing.
Effect of the present utility model: owing to utilize counterweight that valve plate is risen to normally open, do not need source of the gas, and avoided because of the source of the gas excessive accident action that causes valve that loses or fluctuate; Only when valve need be closed, just need source of the gas to promote cylinder moving.This poppet valve economical operation, safe and reliable, simple in structure, the operation maintenance easy maintenance, extensively model is used for the occasion that industry valves such as metallurgy, chemical industry, the energy, machinery need often go into operation and do.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Among the figure, part 1 is a cylinder, and part 2 is valve rods, and part 3 is valve rod postive stop baffles, and part 4 is vavle shelves, and part 5 is valve rod sealing members, and part 6 is valve plates, and part 7 is valve base seals, and part 8 is valve seats, and part 9 is static pulley, and part 10 is lifting ropes, and part 11 is counterweights.
As shown in the figure, poppet valve, mainly form by cylinder 1, valve rod 2, valve rod postive stop baffle 3, vavle shelf 4, valve rod sealing member 5, valve plate 6, valve base seal 7, valve seat 8 etc., static pulley 9 is installed on vavle shelf 4, lifting rope 10 1 ends are fixed on the valve rod 2, and lifting rope 10 the other ends static pulley 9 of having mercy on links to each other with counterweight 11.During work: the valve plate 6 that counterweight 11 will link to each other with valve rod 2 by lifting rope 10 rises to often to go into operation makes state, and when the needs throttle down, cylinder 1 moves downward and promotes valve rod 2 and valve plate 6, with valve closing.
