Description

A kind of valve opening and closing device

Technical field

The utility model relates to valve technology field, particularly, relates to a kind of valve opening and closing device.

Background technique

Along with the progress of society, various pipelines are more and more, and the keying of pipeline control unit " valve " has also been proposed higher, more requirement; Valve manual opening-closing device all is to adopt fixedly dedicated handle or handwheel devices basically in the market; The drive unit that belongs to the traditional open formula, every deck valve door all is furnished with a cover, just anyone random opening/shutting valve; Do not have the anti-function that opens by mistake; And cost is high, and it is big to take up room, and does not meet the requirement of " low-carbon environment-friendly " advocated in the world at present.In addition, " locking " installs also to have the drive unit of some valves to have in the market, but complex structure; It is more loaded down with trivial details to operate; Cost is high, therefore only on some some pipelines high-grade, particular importance, uses, and is not accepted by general marketplace.

The model utility content

To the defective that exists in the existing technology, the purpose of the utility model provide a kind of simple and compact for structure, reliability is high, versatility good, with low cost and have an anti-valve opening and closing device that opens by mistake function.

For reaching above purpose; The technological scheme that the utility model adopts is: a kind of valve opening and closing device; Comprise valve shaft, valve body, valve seat, valve plate and handle; Valve shaft is made up of valve shaft head and valve shaft body, and the valve shaft body passes the manhole that is located at valve body, valve seat and valve plate center successively and is fixedly connected with valve plate, and the valve shaft head is positioned at the valve body over top; The valve shaft head is provided with the interior six side's blind holes that match with the outer six side operating ends of handle along axis, and the valve shaft body is provided with the locking member that connects with valve body.

Further, said locking member comprise be located at valve shaft body top and from the extended fan-shaped bump of the axis of valve shaft body, be located at fan-shaped spacing hole and bolt on the fan-shaped bump; The top of valve body is provided with the scalloped recess that the fan-shaped bump stroke is provided, and is provided with screw-threaded counterbore in the scalloped recess, and bolt screws in the screw-threaded counterbore through the fan-shaped spacing hole on the fan-shaped bump.

Further again, the central angle of fan-shaped spacing hole is 90 degree, and the central angle of scalloped recess is 90 degree.

Further, the thickness of fan-shaped bump is 3-5 centimetre, and the degree of depth of scalloped recess is 5-7 centimetre.

Further, the valve shaft head is provided with the aperture indicating arrow, and the line of direction that the aperture indicating arrow is indicated and the sealing surface of valve plate are positioned at same plane.

The beneficial effect of the utility model is:

The first, simple in structure.The most outstanding characteristics of the utility model are exactly not have fixing drive unit, when valve need open and close, can operate through a portable handle of plug rapidly.

The second, highly versatile.The valve of many deck valves door or plurality of specifications can adopt same handle, thereby can effectively reduce engineering cost, and the valve of particularly big specification (DN200-DN300) only needs to plug portable handle and adds just light opening/shutting valve of suitable long sleeve.

Three, it is obvious to prevent opening by mistake effect.The valve opening and closing device that the utility model provides has locking function, can prevent effectively that other people from arbitrarily opening by mistake closing valve, is specially adapted to the equipment of no worker monitor.

Four, the utility model is few with material, has played the effect of " energy-conservation ", complies with the requirement of social progress development, and economical, societal benefits are obvious.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1; The valve opening and closing device that the utility model provided; Comprise valve shaft 1, valve body 2, valve seat 3, valve plate 4 and handle 5; Valve shaft 1 is made up of valve shaft head 105 and valve shaft body 106, and the valve plate axis hole 201 that valve shaft body 106 passes the manhole that is located at valve body 2, valve seat 3 centers successively and is located at valve plate 4 centers is fixedly connected with valve plate 4, and valve shaft head 105 is positioned at valve body 2 over top; Valve shaft head 105 is provided with the interior six side's blind holes 101 that match with the outer six side operating ends of handle 5 along axis, and valve shaft body 106 is provided with the locking member that connects with valve body 2.

Shown in Fig. 2-4, said locking member comprise be located at valve shaft body 106 tops and from the extended fan-shaped bump of the axis of valve shaft body 106 103, be located at fan-shaped spacing hole 104 and the bolt 6 of spacing usefulness on the fan-shaped bump 103; The top of valve body 2 is provided with the scalloped recess 202 that fan-shaped bump 103 strokes are provided, and is provided with screw-threaded counterbore 203 in the scalloped recess 202, and bolt 6 screws in the screw-threaded counterbore 203 through the fan-shaped spacing hole on the fan-shaped bump 103 104.
