Abstract
The utility model relates to a vertical angle stop valve, a triangle valve and a vertical angle type reversing multiple-way valve, providing a simple vertical angle type fast plug cock valve which is characterized in that A plug cock conical surface cuts to small ends from the upper end of a passageway mouth along the direction of big ends closing the plug cock contacted with a horizontal passageway mouth to form a transferring passageway communicated with the inlet and outlet mouth passageways. The utility model has the advantages of simple structure, convenient operation, small fluid resistance, short start-stop time, easy adjustment and easy casting or compression molding into an information. The utility model just needs a valve body, a plug cock and an axially adjusting screw or nut, being used for reversing allocation multiple-way valves.
Description
The present invention relates to angle shut-off valve, triangle vavle and right-angle type commutation multiple-way valve device.
Heating installation angle shut-off valve now (look into " 80 year June 24,44 of practical five metals handbook Shanghai five metals purchasing and supply station), triangle vavle (the same 25,3), right-angle type stop valve (looking into " mechanical engineering manual " Figure 78,7-4) are all realized opening and closing by lifting screw.Their fluid resistance maximum, opening and closing time are grown (" mechanical engineering manual " table 78,7-1), and complex structure, and part is more.
Purpose of the present invention provides a kind of quick stopcock of easy right-angle type that has improved, and it can fast and effeciently realize opening and closing.
Invention is achieved in that adopts cock to open and close, the cock conical surface from the upper end, passway of the big extreme direction of nearly cock of horizontal channel mouth corresponding position with the bottom by the cock small end.The space of reserving after cutting constitutes can connect the gangway for transhipment of importing and exporting passage; The full surface that cock has at least part to be close to the rotation entity can cover in the horizontal channel mouth where necessary fully, to realize closing of valve.
The present invention only needs valve body, cock and adjusting screw or three parts of nut, and is simple in structure, is easy to casting or compression molding forming, easily processing, and weight/power ratio is lighter mutually with other cock in this cock; Fluid resistance is less, and opening and closing time is short, and the present invention also can be used for commutation and distributes multiple-way valve.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing of the quick stopcock of right-angle type of proposition according to the present invention.
Describe detail and the working condition that proposes according to the present invention in detail below in conjunction with Fig. 1.
This valve comprises a valve body (1), is shaped on the conical bore that cooperates with circular cone cock (2) in its Vertical direction, and circular cone cock (2) is housed in the hole.The top of conical bore has step hole, is shaped on screw thread in the hole, and axial adjustment screw (3) is by being threaded into step hole, with realize to the qualification of cock axial position or when requiring sealability higher to the compacting that screws of stuffing box packing (4); The below of conical bore has vertical passage; The direction vertical with the conical bore shaft axis has the horizontal channel that communicates with conical bore.Cock among the figure (2) is in the full open position, and the improvement face (being gangway for transhipment) of cock this moment is over against the horizontal channel mouth.Gradually during the steering horizontal passway, rate-of flow will be reduced until zero along axis when rotating the cock sealing cone that cock makes part be close to the full surface shape of rotation entity gradually.
According to same design principle, the present invention also can be applicable to commutation and distributes multiple-way valve.It below is the logical valve arrangement that proposes according to same design principle.
Fig. 2 distributes three-way valve for the right-angle type commutation.
Fig. 3 distributes four-way valve for the right-angle type commutation.
Fig. 4, Fig. 5 distribute five-way valve for the right-angle type commutation.
Fig. 6 ends valve for right-angle type five roads.
The common trait of above multiple-way valve is: have a plurality of horizontal channels that communicate with conical bore on the valve body (1); Valve body conical bore below has vertical passage, and the circular cone cock has a plurality of gangway for transhipments of importing and exporting passage that are used to connect.
The operating principle of above multiple-way valve is the same with the operating principle of the quick stopcock of right-angle type of Fig. 1, valve full open when cock improves face over against the horizontal channel mouth; When the not improved outer conical surface of cock gradually during the steering horizontal passway, valve medium stream flow will reduce gradually until zero.
Cock among Fig. 4 (2) is also applicable to a tool even numbers horizontal channel valve, as two horizontal channels valve, and four horizontal channel valves or the like.
The axial position of cock also can limit by the structural type of axial adjusting nut (5) among Fig. 2, and realizes the compacting to stuffing box packing (4).
Claims (3)
1, the quick stopcock of a kind of right-angle type comprises valve body (1), is shaped on the conical bore that cooperates with circular cone cock (2) in the Vertical direction of valve body (1), and cock (2) is housed in the hole.The axial position of cock screws in the interior or valve body conical bore outside thread realization of step tapped hole on corresponding conical bore top by adjusting screw (3) or adjusting nut (5).Cock (2) and adjusting screw (3) or adjusting nut (5) but between casting resin in case of necessity (4).The below of taper hole has vertical passage, and the direction vertical with the conical bore shaft axis has the horizontal channel that communicates with conical bore.It is characterized in that: the cock conical surface from the upper end, passway of the big extreme direction of nearly cock of horizontal channel mouth corresponding position with the bottom by the cock small end, the space of reserving after cutting constitutes the gangway for transhipment that can connect the import and export passage.
2,, it is characterized in that to have a plurality of horizontal channels on the valve body (1) according to the quick stopcock of the described right-angle type of claim 1.
3,, it is characterized in that the circular cone cock can have a plurality of gangway for transhipments according to the quick stopcock of the described right-angle type of claim 1.
