The utility model relates to an automatic reversing valve which comprises a valve body and a valve core, wherein the valve core is arranged in the valve body, the valve core is connected with a valve rod, the valve rod comprises an upper valve rod and a lower valve rod, the lower valve rod is connected with the valve core, the upper valve rod is connected with a driving mechanism, the driving mechanism is controlled by a controller, and the upper valve rod is detachably connected with the lower valve rod. The valve rod is designed in a split way, and the main components of the controller and the valve body can be assembled and disassembled as two discrete components: therefore, during production, parallel line production can be carried out to improve the efficiency; and in maintenance, the component with the problem can be independently removed for maintenance, and the time cost is saved by replacing the spare component.
Description
Technical Field
The utility model relates to an automatic reversing valve.
Background
The existing automatic reversing valve generally comprises a valve body, an opening and closing part, a valve cover, a valve rod, a transmission mechanism, a controller, a sealing part and an installation part, wherein the lower end of the valve rod is fixedly connected with the opening and closing part through a connector, the valve rod and the valve cover are compressed and sealed through a packing gland, and the upper end of the valve rod is fixedly connected with the transmission mechanism through the connector. Because the valve body main body is integrally connected with the controller through the valve rod, in the production and assembly link, the valve body main body and the controller must be sequentially assembled as a whole, the assembly operation cannot be performed in parallel, and the production efficiency is low; in the maintenance and overhaul link, any part has a problem, and must be integrally dismantled and maintained, so that the normal use is influenced, and the cost is high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects pointed out by the prior art, the utility model provides an automatic reversing valve which is realized by the following technical scheme.
The automatic reversing valve comprises a valve body and a valve core, wherein the valve core is installed in the valve body, the valve core is connected with a valve rod, the valve rod comprises an upper valve rod and a lower valve rod, the lower valve rod is connected with the valve core, the upper valve rod is connected with a driving mechanism, the driving mechanism is controlled by a controller, and the upper valve rod is detachably connected with the lower valve rod.
Further, lower valve rod is provided with positioning groove, it is provided with the reference column to go up the valve rod, positioning groove is provided with first mounting hole, the reference column is provided with second mounting hole, the reference column is arranged in positioning groove, first mounting hole and second mounting hole aim at and pass the screw, screwed connection has the nut to the realization is fastened up last valve rod and lower valve rod.
The utility model has the beneficial effects that: compared with the prior art, the valve rod is designed in a split manner, and the main components of the controller and the valve body can be assembled and disassembled as two discrete components: therefore, during production, parallel line production can be carried out to improve the efficiency; and in maintenance, the component with the problem can be independently removed for maintenance, and the time cost is saved by replacing the spare component.

Detailed Description
The present invention is further illustrated by the following examples, which are only a part of the examples of the present invention, and these examples are only for explaining the present invention and do not limit the scope of the present invention.
As shown in fig. 1, an automatic reversing valve comprises a valve body 1 and a valve core 2, wherein the valve core 2 is installed in the valve body 1, the valve core 2 is connected with a valve rod 3, the valve rod 3 comprises an upper valve rod 31 and a lower valve rod 32, the lower valve rod 32 is connected with the valve core 2, the upper valve rod 31 is connected with a driving mechanism 4, the driving mechanism 4 is controlled by a controller 5, and the upper valve rod 31 is detachably connected with the lower valve rod 32.
The valve rod is designed in a split way, and the main components of the controller and the valve body can be assembled and disassembled as two discrete components: therefore, during production, parallel line production can be carried out to improve the efficiency; and in maintenance, the component with the problem can be independently removed for maintenance, and the time cost is saved by replacing the spare component.
Further, referring to fig. 2 and 3, the lower stem 32 is provided with a positioning groove 321, the upper stem 31 is provided with a positioning column 311, the positioning groove 321 is provided with a first mounting through hole 322, the positioning column 311 is provided with a second mounting through hole 312, the positioning column 312 is disposed in the positioning groove 321, the first mounting through hole 322 and the second mounting through hole 312 are aligned and pass through a screw 6, and the screw 6 is connected with a nut 7 to fasten the upper stem 31 and the lower stem 32.
Further, as shown in fig. 4, the valve body 1 is a four-way valve body, outlets of the four-way valve body 1 are distributed along the circumference at equal intervals, and the valve core 2 rotates in the valve body to change the circulation direction of the four-way valve body.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
