Abstract
The utility model discloses a slide valve with rolling wheels. The slide valve with the rolling wheels comprises a valve casing and s slide plate, wherein the valve casing is rectangular, the left and right sides inside the valve casing are provided with rolling wheels, the slide plate is in sliding connection with the rolling wheels, and the length of the valve casing is twice of the length of the slide plate. The slide valve with the rolling wheels has the advantages that the slide valve is provided with the rolling wheels, the friction force of the slide plate during opening and closing can be remarkably reduced, labor is saved during operation, noise is small, the edge of the slide plate is not easily abraded, and the service life is long.
Description
Technical field
The utility model relates to a kind of guiding valve, more precisely a kind of guiding valve with roller.
Background technique
Guiding valve is that a kind of structure is comparatively simple, lower-cost valve, but because the pressure of the suffered fluid of sled surface is larger, guiding valve of the prior art, when opening and closing, is sliding friction between slide plate and valve casing, not only operation is comparatively required great effort, noise is larger, and the chute on slide plate easy to wear and edge and valve casing, causes leakage, cause the working life of slide plate shorter, need periodic replacement.
Model utility content
The utility model is mainly to solve the existing technical problem of prior art, thereby provides a kind of with roller, can significantly reduce the frictional force of slide plate when opening and closing, operate comparatively laborsaving, noise is less, is difficult for the edge of friction slide plate, the guiding valve with roller that working life is long.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of guiding valve with roller, comprise a valve casing and a slide plate, described valve casing is rectangle, and the left and right sides of the inside of described valve casing is provided with roller, described slide plate and described roller roll and are connected, and the length of described valve casing is the twice of the length of described slide plate.
As the utility model preferred embodiment, the middle part of described valve casing is provided with a contiguous block, is provided with a slide plate through gap on described contiguous block, and described slide plate equates with the thickness of described slide plate through the width in gap.
As the utility model preferred embodiment, the described guiding valve with roller also comprises a screw rod and a handwheel, one end of described slide plate is provided with attaching nut, on described valve casing, be provided with an attachment hole, described screw rod is threaded with described attaching nut, described screw rod and described attachment hole are rotationally connected, and described handwheel is fixedly connected with the end of described screw rod.
The advantage of the guiding valve with roller of the present utility model is: with roller, can significantly reduce the frictional force of slide plate when opening and closing, operate comparatively laborsavingly, noise is less, the edge of the slide plate that is difficult for rubbing, and working life is longer.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
The advantage of the guiding valve with roller of the present utility model is: with roller, can significantly reduce the frictional force of slide plate when opening and closing, operate comparatively laborsavingly, noise is less, the edge of the slide plate that is difficult for rubbing, and working life is longer.
As shown in Figure 1, a kind of guiding valve with roller, comprise a valve casing 1 and a slide plate 2, this valve casing 1 is rectangle, and as shown in Figure 2, the left and right sides of the inside of this valve casing 1 is provided with roller 13, this slide plate 2 rolls and is connected with this roller 13, the length of this valve casing 1 is the twice of the length of this slide plate 2, makes this slide plate 2 can complete in the inside of valve casing 1 operation of opening and closing, can make this slide plate 2 can both be subject to the supporting effect of this roller 13 simultaneously in the whole process opening and closing.
As shown in Figure 2, the middle part of this valve casing 1 is provided with a contiguous block 11, is provided with a slide plate through gap 111 on this contiguous block 11, and this slide plate equates with the thickness of this slide plate 2 through the width in gap 111.This contiguous block 11 is set not only can increase this with the area of contact of guiding valve and the pipeline of roller, improves join strength, can increase the intensity of this valve casing 1 simultaneously.
As shown in Figure 1, should also comprise a screw rod 3 and a handwheel 4 with the guiding valve of roller, as shown in Figure 3, one end of this slide plate 2 is provided with attaching nut 21, as shown in Figure 2, is provided with an attachment hole 12 on this valve casing 1, as shown in Figure 1, this screw rod 3 is threaded with this attaching nut 21, and this screw rod 3 is rotationally connected with this attachment hole 12, and this handwheel 4 is fixedly connected with the end of this screw rod 3.The technology of screw connecting structure is mature and reliable comparatively, and cost is lower, rapid operation.
Below only with a mode of execution, mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to external more function module simultaneously, thereby expands to greatest extent its function.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
