Abstract
An asphalt and heat conduction oil composite rotary valve comprises a valve casing, a valve core, a joint and a bearing. The valve casing and the valve core are provided with inlets and outlets connected with asphalt and heat conduction oil pipes. Four asphalt and heat conduction oil passages which are mutually insulated and formed by the valve casing, the valve core and O-shaped rings are arranged in the rotary valve. A connector on the valve core is connected with a rotary pipeline, a connector on the valve casing is connected with a fixed pipeline, and the bearing is mounted between the valve core and the valve casing. A locking screw used for limiting the valve core from moving axially is mounted on the valve casing which is formed by connecting an upper valve casing with a lower valve casing through screws. The side wall of the upper valve casing is provided with two heat conduction oil pipe connection outlets which are connected with heat conduction oil fixed pipelines respectively, and the side wall of the lower valve casing is provided with two asphalt pipe connection outlets which are connected with asphalt fixed pipelines respectively. The asphalt and heat conduction oil composite rotary valve has the advantages of simple structure, convenience in manufacturing, integration of the asphalt and heat conduction oil pipes on one part, remarkably prolonged service life of equipment, improvement on reliability of the equipment and the like.
Description
Technical field
The utility model relates to a kind of machinery control rotary valve that supplies two kinds of flow of fluid simultaneously, the compound rotary valve of especially a kind of asphalt heat conducting oil.
Background technique
On the pouring machine in road building machine field, realize the heating of embedding pipeline usually with Electric heating, guarantee that cementation of fissures agent pipeline is unimpeded; Though this simple in structure, practical application has difficulties, often take place in the course of the work that electric heating device damages or flexible pipe damages and produce to leak and cause and to work, even entire equipment can not be used.
The model utility content
The purpose of the utility model is the deficiency that exists to existing technology, provide a kind of easy to use, sealing is reliable, the compound rotary valve of pipeline asphalt heat conducting oil anti-blocking, long service life.
For addressing the above problem; The utility model provides a kind of mobile control rotary valve of two kinds of liquid (pitch, conduction oil) that supplies simultaneously; It is the compound rotary valve of asphalt heat conducting oil; It is made up of valve casing, spool, joint, bearing, and the import and export that can be connected with pitch, heat-conducting oil pipes are arranged on described valve casing, the spool; Said rotary valve set inside is by be made up of isolated each other four pitches, conduction oil passage valve casing, spool and O type circle; Interface on the said spool links to each other with the rotation pipeline, and the interface on the valve casing links to each other with fixing tube, and said bearing is loaded between spool and valve casing; Be equipped with on the said valve casing and be used to limit the axially movable lock screw of spool.
Described valve casing is joined through screw by last valve casing and following valve casing and forms; The sidewall of wherein going up valve casing is provided with two heat-conducting oil pipes that link to each other with the conduction oil fixing tube respectively and is connected outlet, and the sidewall of following valve casing is provided with two pitch pipes that link to each other with the pitch fixing tube respectively and is connected outlet.
The utility model adopts easy sealing configuration, makes the simple in structure of valve, and is easily manufactured, and pitch, thermal conductive oil pipeline are compounded on the parts, significant prolongation the working life of equipment, improved the reliability of equipment.

Embodiment
To combine below accompanying drawing to the utility model make detailed introduction: Fig. 1,2, shown in 3, the utility model mainly is made up of valve casing, spool 3, joint 1, bearing, and the import and export that can be connected with pitch, heat-conducting oil pipes are arranged on described valve casing, the spool 3; Said rotary valve set inside is by be made up of isolated each other four pitches, conduction oil passage valve casing, spool 3 and O type circle 8; Interface on the said spool 3 links to each other with the rotation pipeline, and the interface on the valve casing links to each other with fixing tube, and said bearing is loaded between spool and valve casing, comprises upper bearing (metal) 7 and lower bearing 11; Be equipped with on the said valve casing and be used to limit spool 3 axially movable lock screws 6.
Described valve casing is joined through screw 9 with following valve casing 4 by last valve casing 2 and forms; The sidewall of wherein going up valve casing 2 is provided with two heat-conducting oil pipes that link to each other with the conduction oil fixing tube respectively and is connected outlet, and the sidewall of following valve casing 4 is provided with two pitch pipes that link to each other with the pitch fixing tube respectively and is connected outlet.
Four annular passs that valve casing shown in the figure and spool 3 forms link to each other with import and export passage separately, and four passages are 10 isolated by six O type circles, seal.The import and export of four passages are connected with spool 3 with valve casing respectively.
Its groundwork principle is following:
Valve casing is fixed, and spool can rotate with respect to valve casing.Conduction oil, the passage of cementation of fissures agent in valve body seal isolated each other, and each passage still keeps sealing isolated in the valve core rotation process.In the embedding operation process, spool rotates with jar seam bar synchronously, does not produce the mechanical interference phenomenon.
More than the disclosed preferred implementation that is merely the utility model; But the utility model is not limited thereto; Any those skilled in the art can think do not have a creationary variation; And, all should drop within the protection domain of the utility model not breaking away from any improvement and the retouching of being done under the utility model principle prerequisite.
