Abstract
The utility model discloses a sealing device on a self-supporting control valve. The sealing device on the self-supporting control valve comprises a pipe body communicated with a valve seat of the control valve. A valve rod is arranged in the pipe body, and a sealing plug is arranged at the lower end of the valve rod. The pipe body comprises a cylindrical pipe communicated with the valve seat and a conical pipe arranged at the lower end of the cylindrical pipe. The upper end of the conical pipe is fixedly connected with the cylindrical pipe through a ring. An elastic rubber mold used for secondary sealing is arranged on the portion, located at the upper end of the sealing plug, of the valve rod. Compared with the prior art, the sealing device on the self-supporting control valve has the advantages that water leakage caused by aging of the sealing plug can be prevented so that the utilization rate of the self-supporting control valve can be improved, and water resources are saved.
Description
Technical field
The utility model relates to valve field, particularly relates to the seal arrangement on a kind of self-erecting type control valve.
Background technique
Seal arrangement on current existing self-erecting type control valve comprises the valve rod being connected with spool, and valve rod is provided with metal bellows, and the lower end of valve rod is provided with the sealing plug for sealing.The sealing plug of this structure easily causes sealing plug aging after long-term use, thereby causes control valve not close, and causes the waste of water resources.
In sum, for the defect of prior art, need especially the seal arrangement on a kind of self-erecting type control valve, thereby solve above-mentioned problem.
Model utility content
The utility model provides the seal arrangement on a kind of self-erecting type control valve in order to solve the problem of prior art.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the seal arrangement on a kind of self-erecting type control valve, comprise the body being communicated with control valve valve seat, in body, be provided with valve rod, the lower end of valve rod is provided with sealing plug, described body comprises the cylindrical tube being communicated with valve seat and is arranged on the conical pipe of cylindrical tube lower end, the upper end of conical pipe is fixedly connected with cylindrical tube by annulus, and the upper end that is positioned at sealing plug on described valve rod is provided with for the flexible rubber pattern of having of secondary seal.
In preferred embodiment of the utility model, described sealing plug semi-surrounding is in the inside of rubber pattern.
In preferred embodiment of the utility model, described rubber pattern is hemisphere.
In preferred embodiment of the utility model, the bottom surface of described rubber pattern is provided with annular seal pad.
The utility model compared with prior art, the advantage having is, in the process using, when valve rod drives in the process of sealing plug decline, drive rubber pattern to decline, in the time of sealing plug and conical pipe sealing, the sealing gasket of rubber pattern lower end will be close to the upper surface of annulus simultaneously, the secondary seal simultaneously forming, so just can prevent by aging and the leaking of causing of sealing plug.Can improve like this utilization rate of self-erecting type control valve, save water resources.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, seal arrangement on a kind of self-erecting type control valve described in the utility model, comprise the body 2 being communicated with control valve valve seat 1, in body 2, be provided with valve rod 3, the lower end of valve rod 3 is provided with sealing plug 4, described body 2 comprises the cylindrical tube 2-1 being communicated with valve seat 1 and is arranged on the conical pipe 2-2 of cylindrical tube 2-1 lower end, the upper end of conical pipe 2-2 is fixedly connected with cylindrical tube 2-1 by annulus 2-3, and the upper end that is positioned at sealing plug 4 on described valve rod 3 is provided with for the flexible rubber pattern 5 of having of secondary seal.
By a kind of preferred version of the present utility model, described cylindrical tube 2-1, conical pipe 2-2 and annulus 2-3 integrated setting.
By a kind of preferred version of the present utility model, described sealing plug 4 semi-surroundings are in the inside of rubber pattern 5.
By a kind of preferred version of the present utility model, described rubber pattern 5 is hemisphere.
By a kind of preferred version of the present utility model, the bottom surface of described rubber pattern 5 is provided with annular seal pad 6.
The utility model compared with prior art, the advantage having is, in the process using, when valve rod drives in the process of sealing plug decline, drive rubber pattern to decline, in the time of sealing plug and conical pipe sealing, the sealing gasket of rubber pattern lower end will be close to the upper surface of annulus simultaneously, the secondary seal simultaneously forming, so just can prevent by aging and the leaking of causing of sealing plug.Can improve like this utilization rate of self-erecting type control valve, save water resources.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
