Embodiment Construction

[0010] Description of the preferred embodiment

[0011] One embodiment of the two-way valve will be described below with reference to the drawings.

[0012] in figure 1 In and 2, reference numeral 10 denotes a two-way valve according to an embodiment of the present invention.

[0013] The two-way valve mainly includes a connecting part 14 detachably mounted on a pair of tubes 12a and 12b, a valve mechanism 16 placed above the connecting part, and a control pressure supply part for supplying control pressure to activate the valve mechanism 16. 18.

[0014] The connecting part 14, the valve mechanism 16, and the control pressure supply part 18 are assembled into a whole.

[0015] As shown in FIG. 2, the connecting portion 14 has a first opening 20a and a second opening 20b on opposite ends thereof, respectively. In addition, the connecting part 14 includes a body 24, a pair of inner members 26 and a pair of lock nuts 28. The body 24 has a fluid passage 22 defined in its interior to...

Abstract

A two-way valve has a valve mechanism comprising a displacement mechanism for opening and closing a fluid passage by an action of a pilot pressure from a pilot port. The pilot port is formed on an annular member disposed between a body and a bonnet and is rotatable circumferentially by the annular member.

Description

Invention field [0001] The present invention relates to a two-way valve having a first opening and a second opening for introducing and discharging pressurized fluid in two directions. Background of the invention [0002] Usually two-way valves have been used in fluid lines. The two-way valve has a first opening and a second opening for introducing and discharging pressurized fluid, and has a valve body that opens and closes a communication passage between the first opening and the second opening. The valve body is operated by the control pressure supplied through the control port. [0003] In the traditional two-way valve, the control port is fixed at the predetermined position of the valve body. If the installation space is small, it is difficult to connect the pipe to the control port during the pipe connection operation. Because the direction of the pipe is limited, it is difficult to connect the pipe to the control port. It is difficult to freely change the direction of the ...
