Abstract
The invention discloses a one-way vacuum valve. According to the one-way vacuum valve, a small-size needle valve and two mechanical valves are combined together. Handles of the mechanical valves are improved so that the size of the one-way vacuum valve is reduced. By means of the design of an inside pore passage inside a valve body, the one-way vacuum valve has two functions of vacuum pumping and flow limiting.
Description
Technical field
The present invention relates to a kind of vacuum valve that is installed on the vacuum vessel, especially refer under the non-transformer environment, be installed in refrigeration system or the heat transfer system, have limited flow and vacuumize the vacuum valve of two kinds of functions.
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, not and entrusted a power line, does not make using and install and being restricted of vacuum vessel, and 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 the 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 the 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 the courage particularly, owing to adopting the heat-conducting system of Evaporating Heat Transfer, need to after adding heat-conducting medium, vacuumize, this just need to a kind ofly can control the vacuum valve that vacuumizes direction, vacuumize the position of being extracted to control at every turn, prevent medium vaporization escape.
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.
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.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, concrete structure comprises: valve shell, spool, needle-valve and snap ring, 5 ducts are arranged in the valve shell, be duct a, duct b, duct c, duct d, duct e, wherein there is screw thread duct a, duct b, c inside, duct, among the b of duct spool are installed, and among the c of duct needle-valve are installed, duct d is communicated with duct a with duct b, duct e is communicated with duct c with duct b.Duct b head has groove, and snap ring is equipped with in inside, prevents that spool from withdrawing from duct b.There is the screw thread that matches with duct b the spool outside, and the spool head has chamfering, can be sealed and matched with duct b bottom chamfer after screwing.After spool is screwed into the chamfering seal closure of bottom and duct b bottom, duct d and duct e can be cut off.The spool top has an interior hex slot, can rotate easily behind the inner insertion hexagon head handle.The screw thread that matches with duct c is arranged on the needle-valve, and after needle valve rotary entered duct c, the top flushed with duct c.Needle-valve adopts existing standard piece on the market.A inside, duct has screw thread, and the outside of duct e has screw thread, can connect pipeline.
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 is so that vacuum valve has valve concurrently and vacuumizes two kinds of functions; Needle-valve is controlled with spring force, has avoided the restriction of power supply.
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.
Fig. 3 is that this device A is to local pipe fitting schematic diagram.
The position of marking is respectively among the figure: 1, duct a; 2, duct d; 3, snap ring; 4, spool; 5, needle-valve; 6, duct e; 7, spool chamfering; 8, interior hex slot; 9, valve shell; 10, duct b; 11, duct c.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Spool 4 tops replace mechanical handle with interior hex slot 8 and the hexagon head handle that can separate, and have reduced the volume of single-way vacuum valve.The opening of duct b10 has draw-in groove, and snap ring 3 is housed, and prevents that spool 4 from withdrawing from duct b10.Spool 4 is screwed into the end, and the chamfering tight closure of spool chamfering 7 bottom the b of duct separated duct e and duct d.The pipeline of vacuum pump is connected on the needle-valve 5 and with needle-valve 5 and opens, and duct e can be vacuumized.Vacuumize complete after, the spool 4 of outwarding winding can make duct d and duct e realize being communicated with.
