方式やコツク方式であり、構造が複雑で、部品点
数が多くて、製造コストが高くなる欠点がある。 Ordinary metal valves cannot be used in water pipes, ventilation pipes, etc. in septic tanks because they have low chemical resistance.
Therefore, valves with a plastic coating or the like are used for applications requiring such chemical resistance, but this type of valve is extremely expensive. Valves made entirely of plastic have also been proposed, but these are of the ball valve type or the pot type, and have the drawbacks of complex structures, a large number of parts, and high manufacturing costs.
更に、弁体をネジ方式で上下動させるバルブ

る。 The technical means of the valve of the present invention includes a valve body having a plurality of flow ports, a valve body with a handle fitted into the valve body, and a nut loaded into the valve body.
All of the above-mentioned members are made of plastic, and a valve seat is provided at the inner bottom end of the valve body, and the flow port communicates through this valve seat, and the tip of the valve body. A valve seat joint is formed in the valve seat, and when this valve seat joint comes into contact with the valve seat, the flow is cut off.The nut is a split nut divided into two along the diameter line, and this nut has a A protrusion is formed on the side surface, and this protrusion is fitted into a groove formed on the inner surface of the valve body, and a nut holder is also fitted and fixed inside the valve body to prevent the nut from slipping out. In addition, a male thread is formed on the outer surface of the valve stem portion of the valve body, and this male thread and a nut are screwed together, and an O
A ring is inserted to prevent water leakage.

ない。 The function of the valve of the present invention is as follows. The two-part nut is fitted into the valve body. Since the protrusion of the nut is fitted into the groove on the inner surface of the valve body, the nut cannot rotate within the valve body. The nut is locked from the outside by the nut holder, so
It does not come out of the valve body. In this way, the nut is held fixed within the valve body. Since the valve stem of the valve body is screwed into the nut, when the valve body is rotated by the handle, the valve body moves in the axial direction. When the valve body is moved to bring the valve seat joint at the tip of the valve body into contact with the valve seat, the flow is blocked, and on the other hand, when the valve body is separated from the valve seat, the flow is enabled. Since an O-ring is provided between the valve body and the inner surface of the valve body, water will not leak through this gap.

Reference numerals 2 and 3 are communication ports opening laterally and downward, and 4 and 5 are pipe connection parts. A pipe (mainly made of plastic) is connected to the inner or outer wall of the pipe connecting portions 4 and 5 using an adhesive. Further, for this purpose, both the inner and outer wall surfaces of the pipe connecting portions 4 and 5 are tapered. 6 is a valve seat, and when the valve body comes into contact with this, the valve closes. Reference numeral 7 denotes the inner wall of the cylinder, and the O-ring of the valve body comes into contact with this wall to prevent the conveyed fluid from leaking to the outside. 8 is a nut loading part, and 9 is a nut presser fitting part. 10 is a valve body, 11 is a valve seat joint, 12 is an O-ring fitting groove, 13 is a valve stem portion having a male thread 14 formed on its outer surface, and 15 is a handle. Such a valve body 10 is integrally molded from plastic. Reference numeral 16 indicates a hole provided for weight reduction and prevention of deformation after molding, and reference numeral 17 indicates an O-ring.
Numeral 18 is a nut to be loaded into the valve body, which is made of plastic and is a split nut divided into two along the diameter line. Reference numeral 19 denotes a rotation prevention protrusion formed on the outer peripheral edge of the nut 18. This nut 18 is fitted into the nut loading portion 8 of the valve body 1 in a circularly joined state. At this time, the protrusion 19 of the nut 18 is fitted into the groove 20 of the valve body 1, and the nut 18 is fixed so as not to rotate within the valve body 1. A nut holder 21 is fitted into the upper end of the valve body 1 after the nut 18 is loaded into the valve body 1 to prevent the nut 18 from slipping out from the valve body 1. Note that the nut retainer 21 is fixed to the valve body 1 using adhesive.

製造が容易である。 A plastic valve made of the parts described above is assembled as shown in FIG. The male thread 14 of the valve body 10 is screwed into the female thread of a nut 18, and the nut 18 is supported within the valve body 1 in a state in which it cannot move up and down and cannot rotate.
5, the valve body 10 moves vertically within the valve body 1 along with this rotation. and,
When the valve body 10 is lowered to its lowest position, the joint 11 at the tip of the valve body 1 comes into contact with the valve seat 6, and the valve is closed. Conversely, when the valve body 10 is raised, the joint 11 moves away from the valve seat 6. Leave and the valve will open. As described above, since the valve of the present invention is entirely made of plastic, it has high chemical resistance and is resistant to corrosion, and is suitable for use in locations where metal products are not suitable, such as inside a septic tank. Furthermore, the valve body of the present invention is not a ball valve type but a vertically moving type, and the number of parts is extremely small, so the structure is simple and manufacturing costs can be reduced. Furthermore, the valve of the present invention does not form the female thread directly on the valve body, but uses a separately molded nut to fix this nut to the valve body, and this nut is split into a split nut. As a result, manufacturing costs can be significantly reduced compared to forming female threads directly on the valve body, and the split nut can be manufactured by molding and does not require cutting.
Easy to manufacture.
