Abstract
The invention discloses a rod type square valve. The rod type square valve comprises a sleeve and a valve core in the sleeve, wherein the sleeve also serves as a valve body and is a hollow cylinder; three holes radially penetrate through the side wall of the sleeve; the valve core is a hollow round rod; the diameter of the outer circle is the same as the inner diameter of the sleeve; and two sealing rings are arranged on the valve core and cut the valve core into three sections. The sleeve also serving as the valve body and the valve core in the sleeve are both rods, so that a plurality of routes are controlled to be connected or disconnected by moving the valve core. Compared with the traditional rotating valve, the rod type square valve has the advantages that the valve core which is a rod is safer and more reliable, leakage and blockage are not easy to cause, and the rod type square valve is applied in a complex environment.
Description
Technical field
The present invention relates to a kind of multiple-way valve, be specifically related to a kind of bar type four directions valve.
Background technique
Multiple-way valve is a kind of rotary valve of controlling multiple-way duct that connects, and can control the closure of a plurality of passages, realizes the break-make control of multiple-way duct.General multiple-way valve adopts rotary spool control.But rotary spool often structure adheres to, and sealing effect is relatively poor, can not use safely for a long time in complex environment.
Summary of the invention
The object of the present invention is to provide a kind of bar type four directions valve, adopt bar type spool design, overcome the problem that existing rotary spool can not be used safely for a long time in complex environment.
For achieving the above object, technological scheme of the present invention is: bar type four directions valve, comprise the sleeve and the interior spool of sleeve that double as valve body, and described sleeve is the cylindrical body of hollow, radially runs through on the sidewall to be provided with three ducts; Described spool is the circular rod member of hollow, and the diameter of cylindrical is identical with the internal diameter of sleeve, and spool is provided with two closed loops, and described closed loop is divided into three sections with spool.
When adopting technique scheme, adopt bar type four directions valve, double as the sleeve of valve body and the spool in the sleeve and be rod member, by the break-make of moving valve core control multichannel.Than traditional rotary valve, the spool of rod member is more safe and reliable, is difficult for occuring to leak and stop up, and is adapted at using in the complex environment.
Further, there are two ducts to be positioned at a side in described three ducts, to meet the needs of use.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is bar type of the present invention four directions valve embodiment's structural representation.
Embodiment
As shown in Figure 1, bar type of the present invention four directions valve comprises the sleeve 1 that doubles as valve body and the spool 2 in the sleeve 1, and described sleeve 1 is the cylindrical body of hollow, radially runs through being provided with three ducts on the sidewall, is respectively air inlet duct 31, air inlet goes out duct 32 and vent 33.Spool 2 is the circular rod member of hollow, and internal cavities is as passage, and the diameter of cylindrical is identical with the internal diameter of sleeve 1, and spool 2 is provided with two closed loops 21, and described closed loop 21 is divided into three sections with spool, forms to advance switching construction.
Adopt bar type four directions valve, double as the sleeve 1 of valve body and the spool 2 in the sleeve 1 and be rod member, by the break-make of moving valve core 2 control multichannels.Than traditional rotary valve, the spool of rod member is more safe and reliable, is difficult for occuring to leak and stop up, and is adapted at using in the complex environment.
Above-described only is preferred implementation of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. bar type four directions valve comprises the sleeve and the interior spool of sleeve that double as valve body, it is characterized in that, described sleeve is the cylindrical body of hollow, radially runs through on the sidewall to be provided with three ducts; Described spool is the circular rod member of hollow, and the diameter of cylindrical is identical with the internal diameter of sleeve, and spool is provided with two closed loops, and described closed loop is divided into three sections with spool.
2. the cubic valve of bar type according to claim 1 is characterized in that having two ducts to be positioned at a side in described three ducts.
