Description
Art
The present invention relates to a kind of new automatic quick closing valve of big orifice pipeline, it is particularly applied to fluid and contains impurity
In big orifice pipeline.
Background technology
Water inlet damage pipe Measure Systems in cabin include the damaged detection of pipeline, the closing of system valve, damaged leak stopping and cabin
A series of integrated treatment measures such as draining.The automatic quick closedown technology of big orifice pipeline be belong to system valve closing measure it
One.The automatic quick closedown technology of pipeline is beyond the automatic detection control system of infringement, especially in the maritime of some non-automated
Carry out damaging the effective measure of pipe in system.The automatic quick closedown technical research of big orifice pipeline, big for future submarine are dived deeply,
The automatic quick closing valve of big orifice pipeline is designed, as a kind of new valve mechanism, due to the design feature of its own,
Breakage occurs for system pipeline, and when piping flow suddenly increases, the valve can reduce aperture automatically until closing, therefore, as pipeline
The safety device of system, research and design to quick self-closing flow control valve door have important practical significance.
China's control valve is industrial to start late.Start to develop the production such as single-seat valve, double-beat drop valve in the 1960s
Product, the product of the mainly imitated former Soviet Union.Due to mechanical industry fall behind, machining accuracy is low, therefore, product amount of leakage compared with
Greatly, the general control requirement of industrial processes at that time but can still be met.The seventies, with the expansion of commercial production scale
Greatly, the raising of industrial stokehold requirement, some control valve products have not adapted to the requirement of production process control, such as to height
The control requirement of the media such as pressure, high pressure drop, low temperature, high temperature and corrosion.Therefore, some Large Scale Petrochemical Enterprises are set in introduction
While standby, some control valves, such as the telescoping valve with balance valve core, eccentric rotary valve etc. are also introduced, for domestic control
Valve manufacturer specifies developing way.Therefore, a kind of simple in construction, the new of deep infringement pipeline technology of being dived greatly for submarine is developed
Type valve is significant.
The content of the invention
In order to overcome existing big orifice pipeline can not realize automatic quick closing valve, to meet that working environment and institute are required
The specific function possessed, the present invention provide a kind of new big orifice pipeline quick closing valve, and the rapid-closure damper in pipe to flowing
Amount, which changes, has good responding ability, and closing motion is sensitive；As far as possible small frictional force is should ensure that between valve interconnecting piece, is selected
The small material of coefficient of friction, improve the reliability of valve closing；Submarine condition of work is taken into full account, avoids valve from making malfunction
Make；Sealed reliable, reduce pollution and accident；With good reliability, less maintenance；It is with good expansibility, can root
It is extended according to the quick change of use environment.
The technical solution adopted for the present invention to solve the technical problems is：In order to effectively improve fast automatic closing valve
Shock resistance, the automatic of new structure quickly use eccentric-butterfly-valve structure；Adopt the structure and overcome other valves
It is smaller to be only applicable to be applied to latus rectum caused by structure, the shortcomings that in the hydraulic system of fluid high purity, improves pipeline and leads to
Footpath, and reduce the volume of valve.
In order to avoid impulse hole plug caused by the corrosivity due to seawater and impurity, the failures such as guiding valve is stuck, reduce and add
Work technological process difficulty, and the degree of dependence to equipment part machining accuracy, using the structure of eccentric-butterfly-valve, meanwhile, in order to
Sealing property is improved, one block is set in the centre position of valve body, spacing effect is played when valve plate rotates to closed position,
Make valve plate that valve be tightly pressed against closed mode in the static pressure of water, in valve body upper-lower position, gear is set with reference to the shape of valve plate
Plate, ensure sealing.
The invention has the advantages that novel valve sealing structure is reliable, there is good response to changes in flow rate in pipe
Ability, closing motion are sensitive；Frictional force is small between valve interconnecting piece, improves reliability；Sealed reliable, reduce pollution and thing
Therefore；With good reliability, less maintenance；It is with good expansibility, can be carried out according to the quick change of use environment
Extension.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is dish plate scheme of installation.
1. valve body in figure, 2. dish plates, 3. water (flow) directions, 4. valve body center lines, 5. sealed sections, 6. valve rods.
Embodiment
Preferably, eccentric sealed butterfly valve is mainly made up of butterfly plate, torque spring, valve rod and valve body；
