Abstract
The utility model discloses a needle valve clack check valve which comprises a valve body (1), a valve clack (2), a valve rod (3), a valve cover (4), a stuffing ring (5), a nut (6) of the stuffing ring, and a handwheel (7); the inner hole of the end part which faces to the handwheel (7), of the valve cover (4) is provided with a gland box (8) and is pressed on the stuffing inside the valve cover by the stuffing ring (5); the nut (6) of the stuffing ring is matched with the thread on the outer circle of the valve cover (4) and presses the stuffing ring (5). When the technical scheme is employed, the valve rod employs a lower thread to be transmitted and connected with the valve cover; the gland box is directly processed on the valve cover; the stuffing ring is directly clamped on the valve cover by the nut of the stuffing ring, thus leading the valve to have the advantages of compact and small structure, simple manufacture and low cost; moreover, a valve clack head capable of freely moving along the axis direction of the valve rod leads the valve to be more easily and reliably sealed.
Description
Technical field
The utility model belongs to the technical field of valve mechanism, and specifically, the utility model relates to a kind of aciculiform valve flap stop valve.
Background technique
Stop valve is a kind of common valve, generally comprise valve body, valve gap, valve rod and open-shut device (flap) etc., open-shut device (flap) moves and the function that realizes opening and closing along the Vertical direction of path center line, on pipeline main rise to cut off or regulate be transferred flowing and throttling action of medium.Valve rod axis is vertical with sealing surface of seat.Valve rod unlatching or shutoff stroke are shorter relatively, and have cut-out action very reliably.In a single day stop valve is in opening state, just no longer includes contact between its valve seat and the flap sealing surface, thereby its sealing surface mechanical wear is less.Variation has taken place in the flow direction of medium during by this type of valve, so the flow resistance of stop valve is higher than other valve.The open-shut device of valve (flap) is made simple, highly versatile.
But stop valve at present commonly used, because Stuffing box will be set separately, valve rod also will form screw-thread fit with special Stem Mut, the linkage structure of flap is very big, thus agree with the complex structure of whole valve, volume big, the cost height.
The model utility content
Problem to be solved in the utility model provides a kind of aciculiform valve flap stop valve, its objective is to make the simple in structure, compact of stop valve.
To achieve these goals, the technological scheme taked of the utility model is:
This aciculiform valve flap stop valve provided by the utility model, comprise valve body, flap, valve rod, valve gap, Gland, gland nut, handwheel, described valve gap is provided with Stuffing box in the endoporus of the end of handwheel, and be pressed on its inner filler by described Gland, screw-thread fit on the cylindrical of described gland nut and valve gap, and Gland compressed.
For making the utility model more perfect, more detailed and concrete technological scheme below also further having proposed, to obtain best practical effect, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
Described valve gap is fixedlyed connected by the mode that is threaded with valve body.
Described flap is conical valve core structure.
Described valve rod and valve gap are for being threaded.
Described valve rod and flap adopt the flexible connection of mechanical stitch formula.
The utility model adopts technique scheme, and valve rod adopts screw thread and valve gap transmission joint down, and Stuffing box is directly processed on valve gap, and Gland is directly pieced together tightly on valve gap by gland nut, makes the valve arrangement compactness, and is small and exquisite, and manufacturing simply, cost is low; Can make valve seal easier, more reliable by movable arbitrarily flap head along the valve rod axis direction.
Description of drawings
Below expressed content of this Figure of description and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model.
The mark that adopts among this figure is respectively:
1, valve body; 2, flap; 3, valve rod; 4, valve gap; 5, Gland; 6, gland nut; 7, handwheel, 8, Stuffing box.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, the utility model is a kind of aciculiform valve flap stop valve, comprises valve body 1, flap 2, valve rod 3, valve gap 4, Gland 5, gland nut 6, handwheel 7.Handwheel 7 adopts with valve rod 3 fixedlys connected.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize making simple in structure, the compact goal of the invention of stop valve, the technological scheme that the utility model is taked is:
As shown in Figure 1, this aciculiform valve flap stop valve provided by the utility model, described valve gap 4 is provided with Stuffing box 8 in the endoporus of the end of handwheel 7, and be pressed on its inner filler by described Gland 5, screw-thread fit on the cylindrical of described gland nut 6 and valve gap 4, and Gland 5 compressed.Be enclosed within gland nut 6 on the valve rod 3 and compress Gland 5 and screw on valve gap 4 with screw thread, with valve gap 4 for flexibly connecting.
The utility model proposes the technological scheme that the roll extrusion of a kind of aciculiform flap is movably connected in the aciculiform stop valve on the valve rod.Stuffing box is directly processed on valve gap, and Gland is directly pieced together tightly on valve gap by gland nut, makes the valve arrangement compactness, and is small and exquisite, make simple, cost is low; Can make valve seal easier, more reliable by movable arbitrarily flap head along the valve rod axis direction.
The utility model has also proposed various exemplifying embodiment as described below, makes things convenient for those skilled in the art to use when implementing the utility model:
Embodiment one:
Between valve gap 4 described in the utility model and the valve body 1 for fixedlying connected.It is that mode by being threaded is carried out fixedly connected that valve gap 4 and valve body 1 concrete is connected., valve body 1 screws with valve gap 4 usefulness screw threads fixedlys connected, convenient for maintaining dismounting and fastening.
