Abstract
The utility model discloses a valve which is arranged at the coupling parts of a liquid conveying pipeline which needs frequent assembling and disassembling or a gas conveying pipeline. The utility model is composed of a casing body, a special catheter with a connection horizontal rod, a shutter, a compression spring, etc. The casing body and the special catheter have a butt-joint by adopting a socket joint mode, liquid conveying and gas conveying can be realized after the shutter is pushed away; because an n-shaped notch whose shape is like the bayonet notch of a bayonet lamp socket is opened on the casing body, when the connection horizontal rod goes into the bottom part of the notch, the casing body and the special catheter can reliably combined together under the function of the compression spring. The utility model has the advantages of simple structure, reliable connection, quick assembling and disassembling, and time saving; the utility model is particularly suitable for the butt-jointed part of the brake conduit of automobiles and tractors and the scoops hung on the automobiles and tractors.
Description
The utility model relates to a kind of transfusion or gas pipeline end-to-end joint part that is installed in the frequent dismounting of needs.And this butt joint must very reliable (security insurance) valve.Hang brake pipeline between the trailer as automobile, tractor and its, all need this butt joint.
At present, this butt joint generally is to adopt be threaded (joint is an external screw thread, and another joint is a female thread) to add the method for sealer circle.Undoubtedly, this butt joint not only need be unscrewed (or tightening) nut when dismounting, nor is very reliable (having loosening possibility because of being threaded).
The purpose of this utility model be to provide a kind of be adapted to be mounted within the transfusion that needs frequent dismounting or gas pipeline end-to-end joint part and this butt joint must very reliable valve.In use, its dismounting rapidly, and do not need to open other valves, can realize safe transfusion or gas transmission rapidly; After it is opened, can realize sealing rapidly, make liquid or come gas no longer to continue outflow.
The purpose of this utility model is achieved in that valve housing import one end that this technological scheme provides is equipped with a valve (circular cone valve or steel ball valve) that relies on pressure spring, hydraulic pressure or air pressure to recover closed position; Its inside diameter surface is equipped with (or one a group) O-ring seal, so as to make its with the special intubate of valve export one end (on the cross bar of connection is arranged) butt joint after be in sealing state.Valve housing exports an end, and then to have two one-tenth along circumference centrosymmetric
V notch v (bayonet slot of shape such as bayonet socket) is so that block connection cross bar on the special intubate.
When valve inlet one was brought in liquid or come gas, valve was at pressure spring.Close (sealing voluntarily is called for short " self-styled ") under the effect of hydraulic pressure or air pressure, liquid or gas just do not flow out.
After the special intubate of outlet one end is inserted housing and backed down valve, can realize transfusion or gas transmission.After special intubate is inserted into the position, as long as rotate to an angle in the direction of the clock, under the effect of pressure spring.Connection cross bar on the special intubate promptly may be stuck in housing and exports an end
The bottom of v notch v.
Advantage of the present utility model is: simple structure connects reliable; Dismounting is quick, saves time.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Accompanying drawing is the structural representation (valve is in the working state of transfusion or gas transmission) of the clamping-type fast assembling-disassembling enclosed valve that proposes according to the utility model.
Among the figure: (1) is housing; (2) be special intubate; (3) for connecting cross bar; (4), (5) are O-ring seal; (6) be valve; (7) be pressure spring; (8) be sheath.
Below in conjunction with structure detail and the working condition thereof of accompanying drawing detailed description according to the concrete valve that the utility model proposed.
Enter at valve before the working state of transfusion or gas transmission, valve housing (1) is what to be separated with special intubate (2).They link to each other with the conduit on the forward and backward both sides of transfusion or gas pipeline end-to-end joint part respectively.Need to prove that herein it is flexible pipe that the conduit on these both sides should have one at least, so just be convenient to implement butt joint.
When valve inlet one was brought in liquid or come gas, valve (6) tightly had been pressed under the effect of pressure spring (7), hydraulic pressure or air pressure on the O-ring seal (5) that housing (1) inwall inlays.So just, liquid or come work import one side of door (6) of sealing gland in the future makes it and can not outflow.
When the connection cross bar (3) on the special intubate (2) is aimed on the housing (1)
V notch v and insert housing after (will be inserted into position), will overcome the elastic force of pressure spring (7), back down valve (6), realize transfusion or gas transmission.At this moment, again with special intubate (2) edge in the direction of the clock
V notch v rotates to an angle (rotate to can not rotate till), under the effect of pressure spring (7), connects cross bar (3) and is just arrived along with special intubate (2) rebounds
The bottom of v notch v and firmly by " lock " reliably.Undoubtedly, when special intubate (2) by after being rebounded, valve (6) must be in the transfusion of being backed down or the working state of gas transmission.In addition, the field also is in sealing state in the seal action of O-ring seal (4) between housing (1) and the special intubate (2).
When needs are taken (valve) apart, special intubate (2) edge is entered housing (1)
The opposite direction of v notch v withdraws from, and itself and housing (1) can be drawn back; And valve (6) will weigh under the effect of pressure spring (7) and gets back to initial sealing state.
It should be noted that at last two part applied metal manufacturings also adopt the method for soldering to be obturaged in order to ensure connecting the sealing of cross bar (3) with special intubate (2) junction point.In order to increase
The rigidity of v notch v, and prevent to connect the touched accident that causes of cross bar (3), so also can increase a tubular sheath (8) in the outside of housing (1).But this sheath embedding is pressed or is sticked with glue knot on housing (1), so that make it to form one.
Claims (3)
1, a kind of be installed in the transfusion that needs frequent dismounting or gas pipeline end-to-end joint part and this butt joint must very reliable valve; This valve by housing (1), special intubate (2), connect cross bar (3), valve (6) (cone gate or steel ball valve), pressure spring (7), O-ring seal (4) and (5) are formed; It is centrosymmetric to it is characterized in that housing (1) outlet one end has two one-tenth along circumference
V notch v (bayonet slot of shape such as bayonet socket), and the last soldering of special intubate (2) has one to connect cross bar (3), it can the edge
V notch v moves, and is stuck in the bottom of this breach under the effect of pressure spring (7).
2, valve as claimed in claim 1 is characterized in that special intubate (2) insertion housing (1) and is compressed spring (7) bounce-back returning, i.e. the connection cross bar (3) of soldering on it is stuck in housing (1)
Behind the bottom of v notch v, still just valve (6) is in the transfusion of being backed down or the working state of gas transmission.
3, valve as claimed in claim 1 or 2 is characterized in that the design of housing (1) outer rim has a tubular sheath (8).
