Embodiment 1

[0018] like figure 1 As shown, a two-way control valve box includes a valve box body 1 and a movable valve stem 5 arranged in the valve box body 1, the valve box body 1 is provided with an inlet 2, and the top of the valve box body 1 is set There is an upper outlet 3, the bottom of the valve box 1 is provided with a lower outlet 4, and the movable valve stem 5 is provided with an upper linkage valve plug 6 and a lower linkage valve plug 7;

[0019] Wherein, the upper outlet 3 and the lower outlet 4 are arranged correspondingly, that is to say: the center of the upper outlet 3 and the center of the lower outlet 4 are on a vertical line, so as to facilitate the sealing of the upper and lower linkage valve plugs ;

[0020] The upper linkage valve plug 6 and the lower linkage valve plug 7 are set corresponding to the upper outlet 3 and the lower outlet 4 respectively, and the distance between the upper linkage valve plug 6 and the lower linkage valve plug 7 less than the distanc...

Embodiment 2

[0025] The difference between this embodiment and embodiment 1 mainly lies in: as figure 2 As shown, based on the above, a filter device 8 is provided on the upper part of the valve box body 1, and the filter device 8 is provided corresponding to the upper outlet 3; the filter device 8 is a filter mesh.

[0026] Based on the above, the upper end of the movable valve rod 5 is set through the filter device 8; this structural design is mainly to facilitate the manual operation of the movable valve rod 5 to move up and down.

[0027] Based on the above, in this embodiment, the inlet 2 is arranged on the side of the valve box 1;

[0028] It should be noted that, in other embodiments, the inlet can be arranged on any side of the valve box; when the inlet is arranged on the top of the valve box, the inlet needs to be connected to the inlet connecting pipe, The inlet connecting pipe is arranged through the filtering device.

[0029] It should be noted that, in other embodiments, th...

Abstract

The present invention provides a bidirectional control valve box which comprises a valve box body and a moving valve stem that is provided in the valve box body; an inlet is provided on the valve boxbody; an upper outlet is provided on the top part of the valve box body; the bottom of the valve box body is provided with a lower outlet; and the moving valve stem is provided with an upper linkage valve plug and a lower linkage valve plug; wherein, the upper linkage valve plug and the lower linkage valve plug are respectively equipped correspondingly with the upper outlet and the lower outlet, and furthermore the distance between the upper linkage valve plug and the lower linkage valve plug is lower than the distance between the upper outlet and the lower outlet; the upper end of the movingvalve stem is equipped to penetrate the upper outlet of the valve box body; and the valve box body is equipped with a filtering device which is equipped correspondingly with the upper outlet. The bidirectional control box adopts the moving valve stem for realizing bidirectional controlling and has the advantages of ingenious conception, scientific designing, flexible control and convenient use.

Description

technical field [0001] The invention relates to a valve box, in particular to a bidirectional control valve box. Background technique [0002] In the prior art, in order to achieve bidirectional control, bidirectional control valves are mostly used, but for some technical fields, valves are not suitable for use due to complex structure, high cost, heavy weight, troublesome installation, and limited installation conditions. [0003] In order to solve the above problems, people have been seeking a more ideal technical solution. Contents of the invention [0004] The object of the present invention is to aim at the deficiencies of the prior art, thereby providing a two-way control valve box with ingenious conception, scientific design, flexible control and convenient use. [0005] In order to achieve the purpose of the above invention, the present invention provides a two-way control valve box, the two-way control valve box includes a valve box body and a movable valve rod a...
