Abstract
The invention discloses a one-way vacuum valve convenient to joint. A small needle valve and a mechanical valve are combined together by the device, the volume of the valve can be reduced by improving a handle of the mechanical valve, the device has two functions of vacuumizing and limiting the flow rate through the design of an inner pore duct of the valve, and a pipeline can be conveniently and fast installed by designing a screw cap to be matched with a brass cock.
Description
One, technical field
The present invention relates to a kind of vacuum valve that is arranged on vacuum vessel, especially refer to be arranged in refrigeration system or heat transfer system under the non-transformer environment, have limited flow and vacuumize the vacuum valve of two kinds of functions.
Two, background technique
At present, although solenoid valve, pneumatic valve, mechanical valve, glass valves kind and model are a lot, the valve that is used for vacuum equipment is few, especially the small volume vacuum valve.
The solenoid valve volume can't be accomplished very little, and multi-band has a power line, makes using and install and being restricted of vacuum vessel, is easily had a power failure and without the interference of electricity.Mechanical vacuum valve not only volume is large but also have a handle that exposes, and in vacuum, there be gas leak phenomenon and short problem of correlated parts life-span in various degree in handle shaft.
Do not need power supply in some energy-conserving product runnings, such as courage solar water heater, outdoor vacuum heat-preserving conduit pipe, vacuum heat-preserving transport pipe etc. in wall-hanging courage, all need a kind of valve that does not need that power supply, volume are little, the sealing endurance is good, vacuumizes thing bypass gas leakage.Courage solar water heater in courage particularly, heat-conducting system owing to adopting Evaporating Heat Transfer need to vacuumize after adding heat-conducting medium, and this just need to a kind ofly can control the vacuum valve that vacuumizes direction, vacuumize to control the position of being extracted at every turn, prevent medium vaporization escape.Simultaneously this vacuum valve requires to install simple, is not easy to occur leakage situation.
Three, summary of the invention
The objective of the invention is to design and a kind ofly can control the vacuum valve that vacuumizes direction, escape to prevent the medium vaporization, satisfy simultaneously the needs of fast and convenient installation.
The technical problem to be solved in the present invention is a kind of valve body of design, small-sized needle-valve and machinery valve can be combined; The valve that designs a mechanism removes the handle of machinery valve; Design a kind of vacuum valve, can control the direction that vacuumizes; Design a kind of interface, can be connected with water tank liner with water heater easily.Difficult point is, new opening ways is simple and convenient, and valve body is as far as possible little, when vacuumizing without the bypass gas leak phenomenon.
The technical solution used in the present invention:
A kind of single-way vacuum valve of convenient docking, concrete structure comprises: valve shell, nut, copper washer, valve switch, rubber washer, needle-valve and snap ring, 4 ducts are arranged in valve shell, be duct a, duct b, duct c, duct d, wherein there is screw thread duct b, c inside, duct, and four ducts are UNICOMs, and valve switch is arranged in the c of duct, duct a and duct d can be separated, needle-valve is arranged in the b of duct.There is the screw thread that matches with duct c the valve switch outside, and head has chamfering, can the chamfering bottom the c of duct be sealed and matched after screwing.After valve switch is screwed into the chamfering seal closure of bottom and duct c bottom, can be with duct d and duct a partition.The valve switch top has an interior hex slot, can rotate easily after inner insertion hexagon head handle, has a circle groove on valve switch, and rubber washer is installed.The screw thread that matches with duct b is arranged on needle-valve, and after needle valve rotary entered duct b, the top flushed with duct b.Needle-valve adopts existing standard piece on market.A outside, duct has screw thread, can coordinate with nut, in the middle of nut, a hole is arranged, and with chamfering, pipeline can pass, and can coordinate with chamfering after the pipeline opening enlarging.There is a groove c inside, duct, and snap ring is installed.Copper washer adopts red copper to make.
Beneficial effect of the present invention:
The spool of this vacuum valve and needle-valve and valve shell have lasting sealability with screw-thread fit; Because the needle-valve volume is little, and the handle that do not expose of spool, reduced the volume of vacuum valve; The drill way layout of valve shell inside makes vacuum valve have valve concurrently and vacuumizes two kinds of functions; Needle-valve is controlled with spring force, has avoided the restriction of power supply; Outside with nut, copper washer and with the copper mouth of the chamfering pipeline that is connected, easy for installation.
Four, description of drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the schematic appearance of this device.
Fig. 2 is the generalized section of this device.
In figure, the position of marking is respectively: 1, nut; 2, copper washer; 3, valve shell; 4, needle-valve; 5, valve switch; 6, snap ring; 7, rubber washer; 8, duct a; 9, duct b; 10, duct c; 11, duct d.
Five, embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
During connecting tube, pipeline passes the hole in the middle of nut 1, coordinates with chamfering on the hole after enlarging, and after screwing nut 1, copper washer 2 is connected pipeline with vacuum valve seals.Valve switch 5 tops replace mechanical handle with interior hex slot and the hexagon head handle that can separate, and have reduced the volume of single-way vacuum valve.The opening of duct c10 has draw-in groove, and snap ring 6 is housed, and prevents that valve switch 5 from withdrawing from duct c10.Valve switch 5 is screwed into the end, and the chamfering tight closure of bottom chamfer and duct c10 bottom is separated duct a8 and duct d11.The pipeline of vacuum pump is connected on needle-valve 4 and with needle-valve 4 and opens, and duct b9 can be vacuumized.Vacuumize complete after, the valve switch 5 of outwarding winding can make duct d11 and duct a8 realize being communicated with.
