Embodiment Construction

[0011] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] like figure 1 As shown, an overflow type 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 valve box body 1 The top is provided with an upper outlet 3, the bottom of the valve box 1 is provided with a lower outlet 4, and the moving valve stem 5 is provided with an upper linkage valve plug 6 and a lower linkage valve plug 7;

[0013] 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 that the upper and lower linkage valve plug pairs it seals;

[0014] The upper linkage valve plug 6 and the lower linkage valve plug 7 are set corresponding to the upper...

Abstract

The invention provides an overflow-type bilateral control valve case comprising a valve case body and a movable valve rod. The valve case body is provided with an inlet, an upper outlet and a lower outlet; the movable valve rod is provided with an upper linkage valve plug and a lower linkage valve plug; the upper and lower linkage valve plugs are respectively arranged corresponding to the upper and lower outlets; the distance between the upper and lower linkage valve plugs is less than the distance between the upper and lower outlets; the valve case body is provided with a filter which is arranged corresponding to the upper outlet; the upper end of the movable valve rod is arranged by passing through the upper outlet and the filter in sequence; the movable valve rod is a tube and is provided with an overflow inlet at the upper part; and the lower end part of the movable valve rod is provided with an overflow outlet which is located in the filter. The control valve case adopts the movable valve rod to realize bilateral control, and the filtering and overflowing functions are increased. The invention has the advantages of skillful conception, scientific design, flexible control and convenient use.

Description

technical field [0001] The invention relates to a valve box, in particular to an overflow type two-way 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 purpose of the present invention is to address the deficiencies of the prior art, thereby providing an overflow bidirectional control valve box with ingenious conception, scientific design, flexible control, convenient use, and filtering and overflowing functions. [0005] In order to achieve the purpose of the above invention, the present invention provides an overflow type two-way control valve box, t...
