Technical field
The utility model belongs to the technical field of inside screw non-rising stem type gate valve, relates in particular to a kind of attached regulation locking gate valve.
Background technique
The open-shut device of gate valve is flashboard, and moving direction and the flow direction of flashboard are perpendicular.Gate valve divides by the screw position of valve rod, can be divided into Outside screw stem rising through handwheel type gate valve and inside screw non-rising stem type gate valve.Wherein, Outside screw stem rising through handwheel type gate valve be flashboard together with valve rod with respect to valve body moving linearly on the axial direction of valve rod; Inside screw non-rising stem type gate valve is located at Stem Mut on flashboard, by hand wheel rotating band ovable valve stem, is rotated flashboard is promoted, and the valve rod that is to say inside screw non-rising stem type gate valve is to be hidden in valve body all the time, makes this inside screw non-rising stem type gate valve be difficult to its open degree of judgement.Moreover gate valve does not have lock function, other people can arbitrarily open or close this gate valve.
Summary of the invention
The purpose of this utility model is to provide a kind of attached regulation locking gate valve, and it can know the open degree of this gate valve intuitively.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of attached regulation locking gate valve, this gate valve is inside screw non-rising stem type gate valve, the one end that comprises valve rod is stretched in valve body and is threaded with flashboard formation, above valve body, be also provided with dial, dial is fixedly connected with valve body, the other end of valve rod is connected through dial and from exposing with handwheel in dial, external member is enclosed within on valve rod and external member is connected with threaded stem, indicator of opening is arranged in external member, on dial, be provided with the form appearing for indicator of opening, also comprise the limting mechanism circumferentially rotating for limiting described external member.
2, attached regulation locking gate valve according to claim 1, is characterized in that: described form is formed by straight groove.
On the basis of such scheme and as the preferred version of such scheme: described indicator of opening is formed by club, and this club is fixedly connected with external member.
On the basis of such scheme and as the preferred version of such scheme: described limting mechanism is formed by straight groove and club, and described club extend in straight groove, and the sidewall of straight groove offsets for club.
On the basis of such scheme and as the priority scheme of such scheme: described position-limit mechanism is formed by external member and dial, and the cross section of described external member is polygonal, and the cross section of dial is suitable mutually with the cross section of external member, and dial is enclosed within the outside of external member.
On the basis of such scheme and as the priority scheme of such scheme: also comprise limited wheel and lock, this lock is arranged on described dial, limited wheel and valve rod are connected and on limited wheel, are provided with limited impression, and the latch of lock has the primary importance that stretches into limited impression and the second place that departs from limited impression.
The utility model compared to existing technology outstanding and useful technique effect is:
1, attached regulation locking gate valve of the present utility model, by dial, external member and the indicator structure of starting a banquet are set, makes it possible to know the open degree of flashboard, plays the effect of aperture Flow-rate adjustment, can play to user's pipe network the effect of Primary regulation flow.
2, the structure that attached regulation locking gate valve of the present utility model is also set up limited wheel and lock, can be blocked valve rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model.
Fig. 3 is the structural representation of limited wheel of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-Fig. 3;
Attached regulation locking gate valve of the present utility model, this gate valve is inside screw non-rising stem type gate valve, and the one end that comprises valve rod 1 is stretched in valve body 2 and is threaded with flashboard 3 formation, and these are prior aries, repeat no more here.As everyone knows, inside screw non-rising stem type gate valve and Outside screw stem rising through handwheel type gate valve the most significantly difference feature are in valve rod rotation process, valve rod can not change with respect to the height and position of whole valve body, makes operator can not know intuitively the open degree of flashboard in the process of opening this gate valve.And attached regulation locking gate valve structure of the present utility model can pass through a reference, make operator know intuitively the open degree of flashboard.
This reference can obtain by following technological means: in the present embodiment, be also provided with dial 4 above valve body 2, this dial 4 adopts hollow tubular thing structure, and is carved with graduation line at the outer surface of this hollow tubular thing.Dial 4 is fixedly connected with valve body 2.The other end of valve rod 1 is connected through dial 4 and from exposing with handwheel 5 in dial 4, by apply external force to handwheel, is with ovable valve stem to rotate.External member 6 is threaded with valve rod 1.On dial 4, be provided with form 7, this form 7 is formed by the straight groove being opened on dial 4.In external member 4, be fixed with club 8, this club 8 extend in straight groove, and the sidewall 71 of straight groove offsets for club 8.In the present embodiment, straight groove is to adopt groove structure.As the direct distortion of this structure, can be also the structure of groove, the form on dial is also formed by the material of transparence.The working procedure of this attached regulation locking gate valve is as follows: by rotating handwheel, make valve rod in company with hand wheel rotating, in the rotation process of valve rod, because the sidewall of club by straight groove limits, make external member under the effect of worm structure, external member moves up and down along valve rod axial direction, because the club in external member and the relative position between dial change, thereby obtained flashboard opening value.
In the present embodiment, the cooperation of sidewall 71 and club 8 by straight groove, it rotates with the subsidiary valve rod 1 of restriction external member 6 in valve rod 1 rotation process together as a limting mechanism, so that external member 6 moves along the axial direction of valve rod 1.As the direct distortion of this structure, also can adopt external member cross section exterior contour be shaped as tetragonal structure, in-profile shape and this external member of dial cross section are suitable, do circumferentially to rotate avoiding at the subsidiary valve rod of external member.Certainly, the structure that is shaped as other shape of the exterior contour of external member cross section.
In the present embodiment, club 8 is also as the parts of indicator of opening.Be understandable that, the limting mechanism feelings that have other structure at this attached regulation locking gate valve put, and indicator of opening also can be formed by indentation or the lines of describing.
In order to reach locking, the locking to valve rod, this attached regulation locking gate valve is also provided with limited wheel 9 and lock 10.Wherein, the structure of lock is prior art, repeats no more here.This lock is arranged on described dial, and limited wheel and valve rod are connected and on limited wheel 9, are provided with limited impression 91, and the latch of lock 10 has the primary importance that stretches into limited impression and the second place that departs from limited impression.For the quantity of limited impression 91, it can be also a plurality of can being one.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
