DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for a Y-strainer impurity outlet (hereinafter referred to as a cap).

[0002]

2. Description of the Related Art A cap of this kind has a structure in which a cap with a nut provided with a screw tube at a screw hole (screw) of an outlet is made detachable. Therefore, when removing or attaching the cap (hereinafter, in principle, the removal will be described) to remove fluid, residue (impurities), and the like (residual liquid) remaining on the strainer, Since there is no configuration for removing the fluid or the like, when removing the cap, there is a possibility that the fluid or the like may be blown out at once, and danger, scattering problems, and the like have not been sufficiently avoided. On the other hand, when removing the cap, usually, the spanner is fitted over the nut and the spanner is gently turned. Therefore, in situations where the cap is frequently attached, when the spanner does not fit, etc., the head of the nut may be damaged,
There are issues such as being troublesome.

[0003] As a technical document for resolving the above disadvantages,
The following ideas and inventions are available. In other words, 7-
The structure disclosed in the strainer structure of the circulating liquid cooling device of No. 33846 is that a plurality of grooves are formed in the male screw portion (screw cylinder), and the remaining liquid is removed little by little through the grooves. The structure is such that a residual liquid is removed or a filter is cleaned by using a small amount of liquid drainage by operation. The configuration disclosed in the strainer of Japanese Patent Application Laid-Open No. Hei 6-154521 provides a passage for draining a liquid in a plug of a cap. It is an easy cylindrical structure. JP-A-7-
The structure disclosed in the valve member built-in type strainer of No. 303806 is a structure in which a plug (cap) is formed in a cylindrical shape that is easy to attach and detach. The structure disclosed in the strainer structure of Japanese Patent Application Laid-Open No. 5-337309 is a structure in which a cap or a lid plate has a cylindrical shape that is easy to attach and detach.

[0004]

According to the technical literature, since a plurality of grooves are formed in the male screw portion, even if the rotating portion (cap) is slightly unscrewed, the residual liquid is removed. There are problems such as the necessity of prompt response and the frequency of failure increasing. The rotating part is a conventional cap with a nut, and has a similar problem. Is for draining the liquid from the passage of the plug, but has a different structure from the cap, is troublesome, and has a problem that some problems remain in securing safety when removing the cap. still,
Although the cap is considered to be a structure for gripping, it does not have a grip dimension, and thus has a problem that lacks ease, ease, quickness, and the like of removal. Although the plugs and caps are considered to have a structure for gripping, they do not have grip dimensions, and thus have a problem of lacking in easiness, easiness and quickness of removal.

DISCLOSURE OF THE INVENTION The present invention is intended to reliably and simply eliminate residual liquid and residual pressure of a strainer, to avoid danger, scattering problems, and the like, and to provide a cap body with a grip dimension. It is intended to facilitate, speed up and simplify the removal of the cap to solve the conventional problems.

According to a first aspect, one end of the strainer is fitted inside.
The cap detachably attached to the Y-strainer impurity outlet is a screw tube screwed to the screw of the impurity outlet, and the base tube portion of the screw tube is left except for the base tube portion of the screw tube.
A plurality of grooves vertically extending toward the free end of the screw cylinder, a cylindrical cap body larger than the screw cylinder having a grip size of 3 cm to 6 cm connected to the screw cylinder, and One or several holes provided in the cap body,
And a sealing means provided on a base end surface of the screw cylinder .

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, since the cap body of the cap provided at the Y-type strainer impurity outlet has a grip size, it can be easily and reliably gripped by hand.
The cap and strainer can be removed. Therefore, the residue of the strainer can be eliminated simply and quickly. At this time, since a groove is formed in the screw cylinder, residual liquid, residual pressure, and the like can be removed little by little, so that there is a feature that danger, scattering problems, and the like can be avoided. When the cap is removed, the sealing means is buried in the base end surface of the screw tube, so that the cap can be easily and reliably removed regardless of the sealing means. By repeating the above operation, the cap can be removed, the strainer (filter body) is removed and the outlet and the Y-type strainer are cleaned as in the conventional case. For screwing the cap to the outlet, first, a strainer is fitted to the cap and attached (hereinafter, referred to as fitting), and then the cap is screwed to the outlet. At this time, since the cap body has a grip dimension, it can be easily and reliably grasped by hand, and the cap and the strainer can be attached. Therefore, cleaning / replacement of the outlet and the Y-shaped strainer, the strainer, and attachment of the cap can be performed easily and quickly.

When the cap has a hole, it is removed by using the rod inserted into the hole. It is also possible to provide anti-slip means on the cap body. Further, holes and anti-slip means can be used together.
