Description

The big flow vessel valve of piston type
Technical field
The present invention is novel to relate to a kind of fire protection sector that is used for, and under the active force of the pressure difference of spool upper and lower sides and spring, closes automatically at ordinary times, through electronic, pneumatic or manually opened, makes the firing-fighting medium folk prescription to a kind of quick opening valve that gets into suppression system.Belong to fire-fighting fire extinguishing, inerting protection field.
Background technique
The vessel valve of current national industry standard GA400-2002 Fire-extinguishing System of Septenary-Fluorine Propane, rated working pressure is on the low side, is 2.5Mpa, 4.2MPa; Inside nominal diameter is less than normal to be DN32, DN40.
Spool capillary tonifying Qi hole does not have filter, no pressure spring and one-way sealing structure, joins in transportation, bottle assembling, during variation of ambient temperature, and instantaneous beating appears in spool, and the extinguishing medium mistake of storage discharges, and storage pressure is can not long term maintenance constant.
The primary seal circle does not have the reinforcement steel ring, is prone to stretch distortion, spalling, repeatedly seal failure after the keying work, and reliability is relatively poor.
Be connected to the awl pitch thread with container; Screw-down torque is big; Need the configure dedicated frock, need to twine raw meal belt, brush sealer, raw meal belt, sealer are often fallen within the container; Raw meal belt relic, sealer particle often pour vessel valve, conveyance conduit, nozzle when the vessel valve unlatching is spurted, and the fire extinguishing effect is spurted in influence.
Pressure gauge and joint do not have from close structure, are one of reasons of the slow seepage of current vessel valve.
During the auxilliary container of system start-up, need configuration to start bottle group, start-up control power supply, cost rises, and it is loaded down with trivial details to construct.
Summary of the invention
Conventional vessel valve latus rectum is less than normal, pressure is on the low side in order to solve, and there is the accident of long-term slow seepage in the GAUGE CONNECTOR assembly; Stop that spool middle part pore is prone to stop up, during war preparedness on the spool side pressure can not keep constant problem; Reduce the working strength and the difficulty of the assembling of vessel valve and container.The present invention is novel to provide a kind of piston type big flow vessel valve; Valve body, valve gap and spool adopt that Cuprum alloy multiplely forges, stress-removal, passivation technology; Adopted pressure drop piston full-open type heavy caliber valve core structure; Spool capillary tonifying Qi hole adopts sintered sheets to filter, and the unidirectional conical surface linear sealing of steel ball structure is set; Primary seal circle liner strengthens steel ring; Spool primary seal circle cylindrical and the radial seal of valve body piston hole and spool bottom O RunddichtringO and valve body semicircle convex surface potted line double seal mechanism have been designed; The Interface design of valve and container is M80 * 2 straight threads, and it is convenient to install and remove; Designed conical surface round end from the GAUGE CONNECTOR of close property; Valve body has been set up the control interface of giving vent to anger.During unlatching, the diaphragm of releasing of valve body upper end punctures through external force, the top air pressure of releasing, and the pressure of spool upside descends rapidly, and spool moves up under the promotion of downside air pressure and all opens, and extinguishing medium spurts from outlet.
The present invention is novel to be achieved in that the big flow vessel valve of piston type is by valve body, spool, valve gap, primary seal circle, pressing plate, locking plug screw, the pressure cap of releasing, the diaphragm of releasing, spring, explosion diaphragm, the plug screw of releasing, sintered sheets, steel ball, O RunddichtringO, pressure gauge, form from the GAUGE CONNECTOR of close property.Spool is in the closed position under the acting in conjunction of initial tension of spring and upper and lower sides pressure reduction at ordinary times, utilizes primary seal circle cylindrical and the radial seal of valve body piston hole and spool bottom O RunddichtringO and the double seal of valve body semicircle convex surface potted line; In the closed position at ordinary times from close property meter connector, stopped the long-term slow leakage problems of GAUGE CONNECTOR assembly; Spool capillary tonifying Qi hole is provided with filters and unidirectional steel ball, in vibrations and temperature variation, guarantees that side pressure does not reduce on the spool, has solved the difficult problem that vessel valve does not open by mistake; The Interface design of vessel valve and container is M80 * 2 straight threads, and dismounting is rapid; The valve body middle and upper part is processed with the control interface of giving vent to anger, and can directly take over to start auxilliary bottle group.During unlatching; The diaphragm of releasing of valve body upper end is through electronic, pneumatic or manually bounce and puncture; The top air pressure of releasing, because the air compensation of pore is much smaller than air leakage amount, the pressure of spool upside descends rapidly; The spool unlatching that under the promotion of downside air pressure, moves up, extinguishing medium spurts from outlet.
The invention has the beneficial effects as follows: the instantaneous relase accident of having eliminated that vessel valve unloads in transportation, steel cylinder assembling, having caused when normal vibrations and variation of ambient temperature in the field-mounted process; It is big to have solved vessel valve and container assembling moment; Problem during assembly fee; Stop the long-term slow leakage problems of GAUGE CONNECTOR assembly, the intensity and the working life that have strengthened the primary seal circle, simplified the initiatively adapter configuration of the auxiliary bottle group of the chain unlatching of steel cylinder.When protecting identical protective area, reduced the quantity of bottle group.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the novel section of structure of the present invention.
