Abstract
The utility model relates to a valve stem structure for a butterfly valve. The structure is characterized in that an upper valve stem is connected with a lengthening bar, and a connector is arranged between the upper valve stem and the lengthening bar. When the structure is in use, the butterfly valve can be embedded underground through the arrangement of the connector and the lengthening bar; moreover, operation can be carried out through a valve opening degree indicator connected with the lengthening bar, which can intuitively reflect the opening degree of the valve; and meanwhile, the needed rotation direction and cycle number of the valve in a whole course can be known, thereby providing convenience for future repair and maintenance.
Description
Technical field:
The utility model relates to the technical field of valve, specifically a kind of stem structure that can buriedly be used for butterfly valve.
Background technique:
Existing reed valve generally is used for the connection of ground pipeline at present, the valve rod of butterfly valve only is exposed to the surface of valve body, owing to water delivery and all buried reason of distributing pipe line, existing reed valve is installed in the underground utility, operation inconvenience, the work effect stability is poor, brings greater inconvenience in the future maintenance and maintenance, can not satisfy the needs that reality is used.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved butterfly valve, and it can overcome, and butterfly valve is installed in the underground utility in the prior art, operation inconvenience, the some shortcomings of work effect stability difference.
To achieve these goals, the technical solution of the utility model is: a kind of stem structure that is used for butterfly valve, it mainly comprises upper valve rod, it is characterized in that: upper valve rod links to each other with an extension bar, is provided with connector between upper valve rod and the extension bar.
Butterfly valve of the present utility model is by the setting of connector and extension bar during use, it is underground that butterfly valve is imbedded, and can operate by the valve opening indicator that links to each other with extension bar, the aperture that can reflect valve intuitively, can also know simultaneously the omnidistance needed sense of rotation of valve and the number of turns, make things convenient for maintenance and maintenance in the future.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises upper valve rod 1, and its difference with the prior art is: upper valve rod links to each other with an extension bar 2, is provided with connector 3 between upper valve rod and the extension bar.Attachment hole between upper valve rod and the connector is oval, and the attachment hole between extension bar and the connector is a square hole, and extension bar and connector external packets are wrapped with guide bushing.Extension bar is a square shaft, and square shaft is of a size of 40*40mm, and the attachment hole between extension bar and the connector is of a size of 40*40mm.The top of extension bar is provided with a valve opening indicator.
In force, for the ease of installing and using, extension bar and connector outer wrapping guide bushing, terrestrial operation person handles underground butterfly valve for convenience simultaneously, a valve opening indicator (the valve opening indicator here is a prior art, has just repeated no more its working principle here) has been installed on the top of extension bar, has solved butterfly valve and has been installed on unhandy phenomenon in the underground utility, have good practicability, and the work effect stability.
