Divide length, neck 1n length is more than the length of more than half of valve body 2 in the direction of movement on open position；
As the second antihunting device of valve body 2, equipped with the guide vane 3 with widened section, the widened section is outside the valve body 2
It encloses and broadens contact width；
And the third antihunting device as valve body 2, it is arranged in the main body 1 along the outer radial periphery of the valve body 2
Containment member, the lower end of the enclosing region of containment member until the valve body on fully open position.
The bonnet B is equipped with sloped footing in the end B1 close to 1 side of main body, offers insertion valve on pedestal B1s
The hole OP of bar ST.Shown in Fig. 2 and 4, in the illustrated embodiment, the geometry of sloped footing B1s is frustro conical, and rear
The outer surface for stating conical tapered portion T fits closely, wherein the tapered portion T is formed on the first end S1a of lead ring S1, institute
It states lead ring S1 and is abutted with pedestal B1s of the bonnet B on the end B1 of 1 side of main body is formed in, shape is not limited to taper, can also
To use such as circular ring shape.
In turn, it is arranged in gap of the Y-valve of the present embodiment between bonnet B and the valve rod ST being inserted into bonnet B
Substantial cylindrical sealing mechanism (i.e. lead ring S1, and 1 or more the ring liner abutted with the other end of lead ring S1
S2), which abuts with the pedestal B1s.Lead ring S1 and the material of liner S2 are preferably heat-resist, frictional property is excellent
Different polytetrafluoroethylene (PTFE), but not limited to this, as long as the material same with PTFE all can be used.
The liner S2 is pushed to the direction of the pedestal B1s by spring SP.Here, being described in detail referring to Fig. 2, the bottom of at
Pass through washer W clamp springs SP respectively between lead ring S1 on seat B1s and liner S2 and terminal link L, wherein the pedestal
B1s is formed in bonnet B close to the end B1 of 1 side of main body, and the terminal link L, which is inserted and fixed, is installed on the another of bonnet B
It holds in B2.
Conical tapered portion T is formed in the first end of the lead ring S1, the first end is formed in bonnet B with described
Pedestal B1s on 1 one side end B1 of main body is abutted, shape on the sliding surface SL of tapered portion T contacted with the valve rod ST
At there is circular arc-shaped recess R.
In this way, being formed on the sliding surface SL of tapered portion T contacted with the valve rod ST arc-shaped recessed according to the present embodiment
Portion R, therefore the abrasion powder generated by the mutual sliding of valve rod ST and sealing mechanism can be collected, and abrasion powder is prevented to be mixed into
In fluid.It is formed with the point of circular arc-shaped recess R over time since spring constantly pushes lead ring S1 referring to Fig. 3
Thin portion T has deforming trend, as shown in Figure 3 (b).As a result, the mill that can prevent the mutual sliding because of valve rod ST and sealing mechanism from generating
Damage powder is mixed into fluid.
