Abstract

PURPOSE:To enable a steam pressure reducing valve to be completely closed, by providing a means for inducing a swirl flow between a strainer and a valve port in the reducing valve so that foreign matter and dust are separated from steam together with a condensate. CONSTITUTION:Steam entering into an annular space 26 from an inlet port 13 passes a screen 10 and then enters in an annular passage 11. This steam is curved in a predetermined direction under action of a turning blade 12 to induce swirl motion when a valve port 8 is opened, and therefore, condensate, fine dust and foreign matter pass around the outside along the outer peripheral wall and drop into a trap valve chamber 19. A float 20 which is floated on condensate so that it is vertically movable, is lifted from and seated on a valve seat 21 to automatically discharge condensate, etc. without releasing steam.

Description

【発明の詳細な説明】 技術分野 本発明は蒸気系に用いる減圧弁に関し、減圧弁に復水と

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a pressure reducing valve used in a steam system, and relates to preventing condensate, dust and foreign matter from entering the pressure reducing valve.

技術的背景 減圧弁は二次側の圧力を検出して、被制御流体の圧力エ

Technical background A pressure reducing valve is a self-cutting adjustment valve that detects the pressure on the secondary side and operates using the pressure energy of the controlled fluid.
If dust or foreign matter gets caught between the valve body and valve seat, damages the valve surface, or gets caught in the sliding parts of the pressure-receiving piston and cylinder, complete closing will not be possible, and the pressure on the secondary side will be lower than that on the primary side. Problems such as rising pressure may occur.

また、蒸気は冷却されると復水になり、特に、通気初期
は配管系が低鍋であるので多量の復水が発生し、蒸気用
減圧弁には多かれ少なかれ蒸気と共に復水が流入する。
In addition, when steam is cooled, it becomes condensate, and in particular, at the beginning of ventilation, a large amount of condensate is generated because the piping system is a low pot, and more or less condensate flows into the steam pressure reducing valve together with the steam.

Due to this condensation, vibrations occur in the pressure reducing valve due to hunting and jitter, which not only hinders operation but also
Water hammer can occur in the piping system, damaging connected equipment, and parts that come into contact with condensate are more likely to corrode, shortening the service life.

従って、蒸気用減圧弁では、塵埃・異物ばかりでなく、
復水の流入も防がなければならない。
Therefore, steam pressure reducing valves are not only susceptible to dust and foreign matter.
Inflow of condensate must also be prevented.

Conventional techniques and their problems Therefore, in the past, a strainer was placed in the primary piping on the upstream side of the pressure reducing valve, and a falling piping was branched to the piping on the upstream side, and a strainer was placed in the piping on the upstream side. A steam trap was placed. Therefore, first, condensate is removed from the system by a steam trap, then dust and foreign matter mixed in with the steam are filtered out by a strainer, and only the steam that does not contain condensate, dust, or foreign matter is introduced into the pressure reducing valve. That will happen.

しかし、この場合でも、完全閉止ができず、漏れが生じ

However, even in this case, complete closure may not be possible, causing leakage and increasing pressure on the secondary side.

This is due to fine dust and parabolites passing through the strainer. It would be possible to reduce the size of the strainer screen's strainer holes and the mesh size, but this also has a practical limit in terms of pressure loss and clogging.

Technical Problem The technical problem of the present invention is to eliminate fine dust and foreign matter that have passed through the strainer out of the system before reaching the pressure reducing valve.

Technical Means The technical means of the present invention taken to solve the above technical problems are as follows: (a) A swirling flow is generated between the strainer and the valve opening of the pressure reducing valve to remove dust and foreign matter from the steam together with condensate. (b) A valve is installed to remove condensate, dust, and foreign matter from the system.

Here, the swirling flow can be generated by directing the fluid in a predetermined direction by the inner wall of the fluid passage, the vane, or the direction of the hole. For example, an annular passage may be formed around the valve opening, in which vanes may be placed or holes may be provided.

また、ストレーナは、例えば、円筒形状のスクリーンを
上記の環状通路を囲んで配置する。
Further, the strainer includes, for example, a cylindrical screen arranged surrounding the annular passage.

The condensate removal valve may be a valve that is manually opened and closed at appropriate times, or an orifice that always releases a constant amount of water, but preferably a steam trap, especially a float type steam trap that does not cause pressure fluctuations in the valve chamber. .

技術的手段の作用 上記の技術的手段の作用は下記の通りである。Action of technical means The operation of the above technical means is as follows.

蒸気は先ずストレーナに入り、スクリーンのこし孔にり
も大きい塵埃・異物はそこでスクリーンに補足される。
Steam first enters the strainer, where the screen captures dust and foreign matter that are too large to fit through the strainer holes in the screen.

周囲の壁を伝わって落下し、排除弁で系外に排除される
。蒸気は旋回流の中央部にあって弁口に向かう。
Steam and condensate that have passed through the screen, as well as fine dust and foreign matter, are rotated by the action of vanes and holes that direct the flow in a predetermined direction, and the condensate, dust, and foreign matter are rotated around the outside by the action of centrifugal force.
It falls along the surrounding walls and is removed from the system by the exclusion valve. The steam is in the center of the swirling flow and heads toward the valve port.

特有の効果 ストレーナのスクリーンを通過する微細な塵埃・異物の
多くが減圧弁の弁口に至るまでに、蒸気から分離されて
系外に排除されるので、弁部や摺動部での挾み込み、弁
部の摩耗・損傷が少なくなり、不完全閉止が少なくなる
Unique Effect: Most of the fine dust and foreign matter that pass through the strainer screen are separated from the steam and removed from the system by the time they reach the valve opening of the pressure reducing valve. This reduces wear and damage to the valve part and reduces incomplete closure.

フルート式スチームトラップ等の復水排除弁はストレー
ナの下流に位置するので、ストレーナを減圧弁と排除弁

Since a condensate removal valve such as a fluted steam trap is located downstream of the strainer, the strainer can be used both as a pressure reducing valve and as a removal valve.

旋回流を起こして復水と微細な塵埃・異物を分離するの
で、分離効率が極めて良くなる。
Separation efficiency is extremely high because it creates a swirling flow to separate condensate from fine dust and foreign matter.

Steam enters the annular space 26 through the inlet 13 and enters the screen 1
0 and enters the annular passage-11. A portion of the steam in the annular passage 11 is supplied to the pilot valve 2 through the passage 6. When the valve port 8 is opened, most of the other steam is transferred to the swirl vane 12.
The trap is bent and rotated in a certain direction by the action of the trap, and by the action of the centrifugal force, the condensate, fine dust, and foreign matter go around the outside and fall along the outer circumferential wall into one valve v of the trap. Steam inside is barrier 1
6 and enters its interior, passing through the vent hole 17 and the valve port 8 to the outlet 14.

The condensate adhering to the swirl vane 12 is blown out to the outside of the swirl by the action of the draining member 15. The condensate enters the valve chamber through the space on the outer periphery of the canopy 18, is lifted up by steam, and is not carried to the valve port 8 of the pressure reducing valve. At the same time, the influence of the swirling flow is blocked by the canopy 18 and does not reach the float 20.

As in this embodiment, an annular passage is provided around the valve port to cause swirling therein, and a cylindrical screen is placed surrounding the annular passage 41! , If you set it to 31,
It has a compact structure and is small, and since steam flows in from all around the screen, the speed at which the screen gets clogged is slowed down, and the interval between blowing dust and foreign matter can be extended.
