Abstract
The utility model provides a two guide structure governing valves, including valve gap, valve body, uide bushing, case, valve rod and upper seal assembly, upper seal assembly be connected with valve body screw-thread fit, valve rod one end and case screw through two nuts, form a whole to in the valve body is packed into from the lower extreme opening of valve body, the valve rod other end passes the middle shaft hole of upper seal assembly, uide bushing and the step hole cooperation assembly on the valve body, the valve gap pass through the bolt and be connected with the valve body. The structure ensures that the valve is accurate, flexible and stable in guide and stable in adjusting performance in the whole operation process, and the valve always keeps bidirectional limiting in the operation process, thereby reducing the noise and prolonging the service life of the valve.
Description
Technical Field
The utility model relates to the valve field, a governing valve specifically says so.
Background
In the automatic control of modern plants, regulating valves play a very important role, the production of which depends on the correct distribution and control of the flowing liquids and gases. These controls, whether energy exchange, pressure reduction, or simple vessel charging, require some final control element to accomplish. The regulating valve is used for regulating the flow, pressure and liquid level of the medium. According to the signal of the adjusting part, the opening of the valve is automatically controlled, so that the adjustment of the medium flow, the pressure and the liquid level is achieved.
At present, the common regulating valve on the market can vibrate due to the guide problem of the valve rod and the impact effect of a medium, so that noise is generated, and the normal use is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a two guide structure governing valves guarantees that the valve direction is accurate, nimble steady, the regulation performance is stable at whole operation in-process, remains two-way spacing throughout the operation in-process, has reduced the production of noise, the life of the valve of extension.
The utility model adopts the technical proposal that: the utility model provides a two guide structure governing valves, includes valve gap, valve body, uide bushing, case, valve rod and upper seal assembly, upper seal assembly and valve body screw-thread fit connection, valve rod one end and case screw through two nuts, form a whole to in the valve body is packed into from the lower extreme opening of valve body, the valve rod other end passes the middle shaft hole of upper seal assembly, the uide bushing cooperate the assembly with the step hole on the valve body, the valve gap pass through the bolt and be connected with the valve body.
Preferably, a sealed cabin is arranged in the middle of the upper sealed assembly, sealed filler is arranged in the sealed cabin, the outermost surface of the sealed cabin is tightly riveted by a retainer ring, and the outer wall of the sealed cabin is provided with an external thread connected with the valve body.
The outer wall of the guide sleeve is provided with an O-shaped ring groove, an O-shaped ring is arranged in the groove, the inner wall of the guide sleeve is matched with the valve core, and the valve core can flexibly move in the guide sleeve.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, the individual numbers represent part names: 1. valve cover 2, valve body 3, guide sleeve 4, valve core 5, valve rod 6 and upper sealing assembly
Detailed Description
In order to make the purpose and technical solution of the present invention more clear, the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a double-guide structure regulating valve comprises a valve cover 1, a valve body 2, a guide sleeve 3, a valve core 4, a valve rod 5 and an upper sealing assembly 6, wherein the upper sealing assembly 6 is matched with the internal thread of the small end of the valve body 2 through external threads, one end of the valve rod 5 is installed in a shaft hole of the upper sealing assembly 6, the other end of the valve rod 5 is screwed with the valve core 4 through two nuts, the lower end opening of the valve body 2 is installed in the valve body 2, an O-shaped ring is installed in an O-shaped ring groove of the guide sleeve 3 and installed at a step hole of the valve body 2, the valve cover 1 is connected with the valve body 2 through bolts, and a tetrafluoro sealing gasket is arranged in the middle of the valve cover.
Finally, it is noted that the above examples are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
