Regarding the self-blade tightening structure of the gland packing described above for various types of valves with a common structure (hereinafter simply referred to as "grand packing valves"), the internal fluid applied to the valve body etc. by the valve pressing blade by the handle etc. when the valve is closed, and the valve body etc. when the valve is opened. Due to the self-tightening effect of pressure, the gland packing is constantly tightened appropriately,
The present invention provides a novel self-closing gland packing valve that can reliably prevent leakage of internal fluid.

にしたものである。Conventionally, in relatively large high-temperature/high-pressure gland seal valves, gland seals, back sheets, etc. have been used as sealing means to prevent leakage of internal fluid from the valve stem penetration part. Grand Patsukin is generally
A plurality of annular packings surrounding the valve stem are installed in a stationary state in the stuffing box through which the valve stem is inserted, and the packing is held down and tightened by tightening and compressing the packings using bolts, etc.・It is designed to prevent leakage of internal fluid.

せるなど、種々の問題点が見られたものである。However, when tightening the gland packing with bolts, the pressure is always constant regardless of the vertical movement of the valve.
If internal fluid leakage occurs due to the elasticity of the gland packing, it is necessary to apply so-called additional pressure to obtain a tight state again, which accelerates the deterioration of the gland packing material and In addition to causing leaks, the gland buffing, which had hardened due to repeated tightening, caused various problems, including a significant decrease in work efficiency when disassembling the valve and replacing the packing. be.

である。In view of these circumstances, the present invention provides the above-mentioned so-called gland packing valve, which includes a valve body, a ring ring provided at the lower end of the valve body that engages with the valve body, and a rim fitted around the valve stem. The lower part of the gland packing holder is inscribed in the bonnet and can be raised and lowered freely, and the gland packing holder attached to the ring edge can be elastically clamped by the packing holder, which solves the problem mentioned above. This has completely solved the problem.

るという格別の作用を奏するものである。[Function] In the self-closing gland packing valve of the present invention having the configuration described above, the packing holder that descends when the valve is closed tightens the gland packing between the rims of the valve stem and tightens the valve body. While lowering and seating the gland packing to provide the necessary tightness to the gland packing, when the valve is opened, the internal fluid pressure applied to the valve body presses the gland packing upward from its bottom via the ring edge, and the self-cutting blade constantly presses the gland packing upward from its bottom. It has a special effect of maintaining a stable state of occlusion of the nucleus.
以下、本発明の構成を図面に示す一つの実施例に従って
更に具体的に述べると、図は玉型弁への適用例を示した
ものであって、図中１は弁面、２は弁座、３は上記弁面

支承するヨークである。Hereinafter, the structure of the present invention will be described in more detail according to one embodiment shown in the drawings. The drawing shows an example of application to a globe valve, in which 1 is the valve surface and 2 is the valve seat. , 3 is a bonnet inserted and welded to the valve surface 1, 4 is the bonnet 3
This is a yoke that is screwed onto the outer periphery of the yoke and supports a bush, a sleeve, etc., which will be described later.
又、５は下端に弁体６を係着し、上記ボンネット３に昇

たものである。Reference numeral 5 denotes a valve body having a valve body 6 attached to its lower end and penetrating the bonnet 3 so as to be able to rise and fall freely, and a ring rim that can slide closely against the inner wall of the bonnet 3 at the lower part of the valve stem. 7 is integrally formed, and the gelande pad 7kin 8 on the ring rim 7,
It is designed to be clamped and locked with a packing holder 9 which is fitted onto the outside of the valve body 5 and slidably fitted into the bonnet 3.

端に螺着されるバネ押え１０、皿バネ１１等を介して上
述したように、弁体の輪縁７とパツキン押え９によって
圧締するようにしたものである。The gland packing 8 is composed of, for example, a plurality of annular packings 8a, and is connected to the washer 8b, the spring retainer 10 screwed onto the upper end of the valve stem 5, the disc spring 11, etc., as described above. It is designed to be clamped by the ring edge 7 of the valve body and the seal holder 9.
尚、上記皿バネ１１は、グランドパツキン８の最低締付
は面圧を維持すると共に、該グランドパツキン８の弾性
を補償するものである。The disc spring 11 maintains the surface pressure of the gland packing 8 when tightened to the minimum, and also compensates for the elasticity of the gland packing 8.

したものである。Next, reference numeral 12 denotes a sleeve which is screwed onto the upper half of the packing presser 9, and is connected to the yoke 4 through a bushing 13.
By rotating a handle 14 fixed to the upper end of the handle 14 in the forward and reverse directions, the valve stem 5 can be moved up and down together with the packing holder 9, allowing the valve to be opened and closed freely. .

のである。Furthermore, 15 is a locking plate attached to prevent the puffkin presser 9 from rotating together with the sleeve 12 when the handle 14 is rotated, and for example, the - end is fixed to the yoke 4, and the other end is fixed to the yoke 4. The end is fitted in advance into a guide groove 9' provided in the axial direction at the middle part of the packing presser 9, so that the packing presser 9 can be slid up and down by a certain amount without rotation.
尚、図中１６．１７はそれぞれ０リングを示す。In addition, 16 and 17 in the figure each indicate a 0 ring.
ところで、ハンドル１４を一定方向に回動させて閉弁す

座２に当接してそれ以上下降しないから、パツキン押え
９のみが下降し、グランドパツキン８を更に圧締してボ
ンネット３との緊塞をより増強し得るのである。By the way, when the handle 14 is rotated in a certain direction to close the valve, the gland packing 8 on the rim 7 at the bottom of the valve stem is tightened in the compression direction as the packing presser 9 descends, and the valve body is lowered and seated. When the handle 14 is further rotated at this time, the valve body 5 comes into contact with the valve seat 2 and does not descend any further, so only the seal presser 9 is lowered and the gland seal 8 is lowered. By further tightening the bonnet 3, the tightness with the bonnet 3 can be further strengthened.
又、弁の全開時等、ハンドル１４の操作を停止している

得られるものである。In addition, since the seal retainer 9 does not move upward when the handle 14 is not operated, such as when the valve is fully opened, the valve stem 5 is moved by internal fluid pressure acting on the lower surface of the valve body 6 and the rim 7 of the valve stem. The chisel is pushed up, slides upward within the bow ring presser 9, and the gland seal 8 is tightened with its own blade between the ring rim 7 and the seal presser 9, and a tightening effect corresponding to the internal pressure is obtained. .

果が期待できるものである。As described above, the self-closing gland puffkin valve according to the present invention sandwiches the gland packing between the gland holder, which moves up and down according to the rotation of the handle, and the ring ring provided at the bottom of the valve stem. Therefore, whether the valve is opened or closed, the gland packing is always tightened with a constant pressure, and an exceptional effect can be expected in that it provides a particularly high tightening effect. be.

の優れた効果を奏するものである。Furthermore, since the valve body, rim, gland packing, and packing retainer are all fitted in contact with the inner wall of the bonnet, when disassembling the valve or replacing the gland packing, all you need to do is remove the bushing and locking plate. This makes it possible to take out all parts from the handle to the valve body directly from the bonnet, and compared to conventional valves, not only disassembly and assembly of the valve, but also replacement of the gland packing etc. can be done from the valve surface or the bonnet. It has various excellent effects, such as being able to do it outside and making it easier to dig.
