Description
Technical field
The utility model relates to valve type technical field, relates in particular a kind of opening and closing high pressure valve easily.
Background technique
At present, high pressure technique has been widely used in the fields such as superhard material manufacture, chemical industry, petrochemical industry, powder metallurgy and geology pharmacological research.Due to being widely used of high pressure technique, the high pressure in high-pressure system or the performance of Super high pressure valve just directly affect reliability, Security and the working efficiency of whole system work.In the system of frequent supercharging and release, a kind of switch easily high pressure or Super high pressure valve more can guarantee the safety and reliability of system, also reduces artificial labor intensity simultaneously.General valve of the prior art does not have effectively to solve above-mentioned switch conveniently and safe and reliable problem.Chinese patent notice of authorization CN 201627931 U for example, November 10 2010 notice of authorization day, the name of innovation and creation is called high pressure air exhaust valve, this Patent Case discloses a kind of high pressure valve, pass through body, spool, filter screen, spring, the structure innovation of air outlet adapter and row's heart core, realize this valve and can often open and close feature easily, but the opening and closing of this Patent Case valve are realized by deadweight and the spring of spool completely, in case of emergency, this valve cannot manual control opening and closing, there is the problem that potential safety hazard and unfailing performance are low.For another example Chinese patent notice of authorization CN 201973267 U, at on 09 14th, 2011 notice of authorization day, the name of innovation and creation is called septum valve, this patent discloses a kind of high-pressure regulation valve, the combined innovation of structure and annexation by valve body and valve rod, has realized this valve and can conveniently control the feature of opening or closing, but the not innovation of the drive unit of this Patent Case valve rod, when actuate valve stem is moved, there is the problem that labor intensity is high.The utility model, by valve body, valve rod, drive unit, connecting rod and the structure of spring and the combined innovation of annexation, provides a kind of switch convenient, and working strength is low, and working efficiency is high, the high pressure valve that safety and reliability are good.
Summary of the invention
The utility model solves general valve in prior art does not have effectively to solve switch inconvenience and the low problem of safety and reliability, a kind of high pressure valve is provided, the combined innovation of structure and annexation by valve body, valve rod and drive unit, the switch of realizing this high pressure valve is convenient, working strength is low, working efficiency is high, and safety and reliability are good.
In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals: a kind of high pressure valve, comprise valve body, valve rod and drive unit, it is characterized in that, described drive unit is provided with piston rod, described valve rod penetrates in valve body, the upper end of valve rod and piston rod interlock, and the lower end of valve rod is provided with the spool suitable with valve body.
When mounted, first valve rod is penetrated to valve body, and in valve body, spool is connected with the end of valve rod, then drive unit is fixed on corresponding position, finally by the other end interlock of the piston rod of drive unit and valve rod, with regard to installation.In use, start drive unit, the piston rod of drive unit stretches out, and valve rod is protruding along with the motion of piston rod, makes the relation that is tightly connected of spool releasing and valve body, now the state of valve body in opening; Again start drive unit, piston rod is retracted, and valve rod, along with the action of piston rod is also retracted, makes spool be connected with valve seal, now the state of valve body in closing.Valve body is the core component of this high pressure valve; Valve rod and spool, for the opening and closing of valve body, valve rod outwards moves, and valve body is opened, on the contrary valve rod inwardly moves, and valve body is closed; Piston rod, with valve rod interlock, piston rod stretches out, and valve rod outwards moves, on the contrary piston rod is retracted, and valve rod inwardly moves; Drive unit, is the power source of this high pressure valve, drives piston rod to stretch out or the reset of retracting.High pressure valve of the present utility model is compared with general valve, as long as start drive unit, just can realize the opening and closing of valve, and the switch of valve is convenient, and working strength is low; Compare with the high pressure air exhaust valve in documents, owing to having increased drive unit and piston rod, in case of emergency, start drive unit, just can close at once or open valve, working efficiency is higher, and Safety performance and unfailing performance are better; Compare with the septum valve in documents, working strength is low.
Preferably, described high pressure valve also comprises connecting rod and free bearing, and one end of described connecting rod is connected with free bearing, and the other end and piston rod are hinged, and middle part and the valve rod of connecting rod are hinged.By lever principle, with less power, just can make valve rod open or valve body, thereby reduce the model of drive unit, reduce costs.
Preferably, described high pressure valve also comprises spring I and positioning plate I, described spring I and piston rod interlock, and the upper end of spring I is connected with positioning plate I.When piston rod stretches out, spring I has the effect of buffering to piston rod, reduce the speed that piston rod stretches out, and then extends the time that valve body is opened, and improves the safety and reliability of this high pressure valve; Meanwhile, when piston rod is retracted, spring I discharges elastic potential energy, increases the speed that piston rod is retracted, and then shortens the time that valve body is closed, and improves the safety and reliability of this high pressure valve.
Preferably, described high pressure valve also comprises spring II and positioning plate II, the upper end interlock of described spring II and valve rod, and the upper end of spring II is connected with positioning plate II.When valve rod outwards moves, spring II has the effect of buffering to valve rod, reduce the speed that valve rod stretches out, and then extends the time that valve body is opened, and further improves the safety and reliability of this high pressure valve; Meanwhile, when valve rod inwardly moves, spring II discharges elastic potential energy, increases the inwardly speed of motion of valve rod valve rod, and then shortens the time that valve body is closed, and further improves the safety and reliability of this high pressure valve.
Preferably, described drive unit is oil engine.Oil engine has advantages of that driving force is large, action is fast and energy consumption is low, and the cost of realizing this high pressure valve is low, and working efficiency is high.
Owing to taking above-mentioned technological scheme, a kind of high pressure valve that the utility model provides has such beneficial effect: the combined innovation of structure and annexation by valve body, valve rod, drive unit, connecting rod and spring, provide a kind of cost low, switch is convenient, working strength is low, working efficiency is high, the high pressure valve that safety and reliability are good.
