Abstract
The utility model relates to a pipeline opening and closing mechanism which comprises a valve, a bonnet, a valve spool, a valve stem, a steel ball, a hose, a sleeve, a reset spring and an adjusting screw. The valve and the bonnet are connected together, the valve spool directly penetrates the valve to be axially fixed on the valve, a spherical groove is formed in the outer circle of the valve spool, the steel ball is arranged in the sleeve which is fixedly connected with the valve, the steel ball sinks into the spherical groove of the valve spool through an opening of the sleeve, the lower end surface of the steel ball is tangent to the upper end surface of the valve stem, the lower end surface of the valve stem is fitted to the rubber hose, the adjusting screw is mounted under the hose and is in threaded connection with the valve, and open degree of the hose can be controlled through the adjusting screw; when the steel ball is in the spherical groove, the hose is in the open state, and the valve stem is rotates; when the steel ball is popped up, the hose is in the closed state. The pipeline opening and closing mechanism has the advantages that an on-off switching function of solutions in pipelines is realized, and the solutions are prevented from mixing and leaking; the pipeline opening and closing mechanism is especially applicable to special connection environments of small space, low pressure, low flow rate, no leakage and no mixed solutions.
Description
Technical field
The utility model relates to a kind of pipeline opening/closing mechanism, particularly a kind of pipeline opening/closing mechanism for multi-pipeline liquid small flow.
Background technique
At present, hydraulic control valve internal structure all adopts valve body and the sealing of spool taper fit, and liquid paths hole directly, radially through valve body and spool, to suitable angular orientation, is carried out shutoff port hole liquid line structure form by spool radial rotary.In engineering application, spool frictional rotation moment is large, and especially machining accuracy is high, coordinates and requires tightly, easily to occur the fault such as leakage and mixed liquid.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of novel hydraulic control valve pipeline opening/closing mechanism, overcomes the defect that the fault such as leakage and mixed liquid easily appears in prior art.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: pipeline opening/closing mechanism, comprise valve body and spool, described spool passes valve body and is axially fixed on valve body, it is characterized in that, described pipeline is elastic hose, described elastic hose is vertical through described valve body, described valve body internal recessing, installs start-stop device in described groove, described spool connects described elastic hose outer wall by described start-stop device.
Described start-stop device comprises steel ball, sleeve, valve rod, elastic element and adjusting screw, on described spool cylindrical, have ball recess, described steel ball is placed in described sleeve, described sleeve is fixedly connected with described valve body, described steel ball sinks to by the opening of sleeve in the ball recess of spool, described steel ball lower end surface and valve rod upper-end surface are tangent, the upper end of described valve rod and described sleeve Spielpassung, described elastic element is enclosed within on valve rod, the upper end of described elastic element connects described valve rod top, the lower end of described elastic element connects described valve body, described valve rod lower end surface and the laminating of described elastic hose, described adjusting screw is installed described elastic hose below, described adjusting screw is connected with valve body screw thread, adjusting screw can be controlled the opening degree of elastic hose.
Pipeline opening/closing mechanism also comprises valve gap, and described valve body and valve gap link together.
Use principle of the present utility model is, in the time that steel ball is in ball recess, the valve rod lower end surface and the elastic hose that are positioned at steel ball below are tangent, and pipeline is opening state; Rotation valve rod, when steel ball is ejected, steel ball band ovable valve stem produces downward displacement, and pressure elasticity flexible pipe makes pipeline closure; Rotation valve rod, in the time that steel ball is placed in the ball recess of spool, valve rod moves up under the acting in conjunction of Returnning spring and elastic hose elastic force, and now pipeline is open mode.
The beneficial effects of the utility model are to have realized the break-make switching function of solution in pipeline, simple to operation, prevent that solution from mixing liquid, leakage, be particularly useful for that space is little, low-pressure, small flow, without leaking, the special JA(junction ambient) of mixed liquid not.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
Fig. 1 is the structural representation of pipeline opening/closing mechanism of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel hydraulic-control valve pipeline opening/closing mechanism, together with valve body 9 is connected by screw with valve gap 1, spool 2 is directly axially fixed at one through valve body 9 by plain washer, spring washer, nut.Valve body 9 structures employing pipe passage modes as for wherein, have been avoided the play of rubber hose 7 in valve body 9 by rubber hose 7, have ensured the reliability of the normal break-make of pipeline.On spool 2 cylindricals, have ball recess, steel ball 3 is placed in sleeve 4, sleeve 4 is fixedly connected with valve body 9, steel ball 3 sinks to by the opening of sleeve 4 in the ball recess of spool 2, steel ball 3 lower end surfaces and valve rod 6 upper-end surfaces are tangent, the upper end of valve rod 6 and sleeve 4 Spielpassung, elastic element 5 is enclosed within on valve rod 6, the upper end of elastic element 5 connects valve rod 6 tops, the lower end of elastic element 5 connects valve body 9, valve rod 6 lower end surfaces and rubber hose 7 are fitted, adjusting screw 8 is equipped with in flexible pipe 7 belows, adjusting screw 8 is threaded with valve body 9, adjusting screw 8 can be controlled the opening degree of flexible pipe, in the time that steel ball 3 is in ball recess, flexible pipe 7 is in open mode, rotational valve core 2, when steel ball 3 is ejected, flexible pipe 7 is in closed condition.
The utility model has been realized the break-make switching function of solution in pipeline, simple to operation, prevents that solution from mixing liquid, leakage, be particularly useful for that space is little, low-pressure, small flow, without leaking, the special JA(junction ambient) of mixed liquid not.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
