Description

本考案は、高圧管路放圧構造に関し、特に霧発生装置に用いられる高圧管路放圧構造に関する。   The present invention relates to a high-pressure line pressure relief structure, and more particularly to a high-pressure line pressure relief structure used in a fog generator.

一般の微粒霧発生装置は、高圧をかけて、噴射ノズルから霧を噴射する。
高圧噴射の操作中に、霧の噴射を停止すると、末端で水が止まり、管内の高圧は放圧されない。高圧ポンプは加圧を停止しているのだが、管内において内圧が充満し、霧の噴射を停止してからも、噴射ノズルから水漏れが起きることが多かった。管内における内圧の充満はポンプの管路の放圧後において、ようやく水漏れが収まる。
このような状況は、霧発生装置の使用において、大きな欠点である。ポンプが加圧していない時でも、ふつう水道の水圧は７kgf/ｃｍ２で、噴射ノズルの圧力値には達していないが、噴射ノズルから水漏れが起きることが多かった。ポンプ停止後の水漏れを防ぐため、入水管および出水管上に対応する電磁弁、タイマなどの装置を装着し、放圧を行なうこと、およびオフされた後の内圧が水漏れを起こすのを防ぐことにより、使用上の安全性および衛生管理を確保した。
しかし、装置の装着は、構造上の装置の増加と不便をもたらし、さらに組立コストおよび材料の増加を招いた。コストおよび構造の設計において、かねてから業界では解決が困難な問題であると考えられてきた。霧発生装置の使用が頻繁になり、様々な場所で使用されるにともない、いかに装置を増やさずに、構造を簡単にし、組立コストを下げるかが重要になり、効果的に従来の管路構造を改良することにより、残圧が使用上の便利さおよび安全性を妨げないようにする。従来の霧発生装置の管路の放圧構造の設計において、さらなる改良が必要である。
特開平８−１７３８６３号公報 A general fine mist generator applies high pressure and injects mist from an injection nozzle.
If the mist injection is stopped during the high pressure injection operation, the water stops at the end and the high pressure in the pipe is not released. Although the high-pressure pump stopped pressurization, water leakage often occurred from the injection nozzle even after the internal pressure was filled in the pipe and the mist injection stopped. The filling of the internal pressure in the pipe finally eliminates water leakage after the pressure of the pump line is released.
Such a situation is a major drawback in the use of fog generators. Even when the pump was not pressurized, the water pressure of the water supply was usually 7 kgf / cm 2 , which did not reach the pressure value of the injection nozzle, but water leakage often occurred from the injection nozzle. In order to prevent water leakage after the pump is stopped, install a corresponding solenoid valve, timer, or other device on the inlet and outlet pipes to release the pressure, and the internal pressure after being turned off will cause water leakage. By preventing it, safety in use and hygiene management were ensured.
However, the installation of the device has resulted in an increase in the number of structural devices and inconvenience, as well as an increase in assembly costs and materials. Cost and structure design has long been considered a difficult problem to solve in the industry. As fog generators are used frequently and used in various locations, it is important to simplify the structure and reduce assembly costs without increasing the number of devices, and effectively improve the conventional pipe structure. The residual pressure does not hinder the convenience and safety of use. Further improvements are needed in the design of the pressure relief structure of the conventional mist generator conduit.

The packing is arranged to prevent water leakage after moving the slide, and a spring is put on the outside of the chain end lump 111, and when the high-pressure water flow returns, the slide body is quickly sealed. The pressure release valve port that penetrates to one end on the water discharge side of the valve is placed, and the plug is pushed inside by a low-pressure spring to form a closure of the pressure release port.

上述したことからわかるように、本考案の高圧管路放圧構造は、高圧水流の出水を停止した時に、還流した高圧水流の圧力を放圧バルブ口から放圧し、バルブ内を低圧状態にし、噴射ノズルが水漏れを起こすのを防ぐことができる。また、高圧管路放圧構造は、構造が極めて簡単であるため、組立にも特別な技術を必要とせず、コストも安価である。   As can be seen from the above, the high-pressure line pressure release structure of the present invention releases the pressure of the refluxed high-pressure water flow from the pressure-release valve port when the high-pressure water flow is stopped, It is possible to prevent the spray nozzle from causing water leakage. Moreover, since the structure of the high-pressure line releasing structure is extremely simple, no special technique is required for assembly, and the cost is low.

以下、本考案の実施形態を図面に基づいて説明する。
図１は本考案の一実施形態による放圧部を示す斜視図である。図２は本考案の一実施形態による放圧部を示す斜視図である。図３は本考案の一実施形態による放圧座（閉鎖状態）を示す断面図である。図４は本考案の一実施形態による放圧座の入水および出水の流動状態を示す断面図である。図５は本考案の一実施形態による還流した高圧水流の水圧が放圧される状態を示す断面図である。
本考案の放圧構造は、中空管状のバルブ１０にまず組立式スライド体１１を装着し、次にスライド体１１内部にはプラグ１３およびスプリング１４を流通孔１２上に装着する。
流通孔１２はT字状を呈しスライド体１１の内部にある。プラグ１３およびスプリング１４は、適時に流通孔１２を閉鎖し、水流の制御を行なう。スライド体１１の入水側の一端に円錐状で硬質プラスチック製のプラグ１５を装着し、入水口を塞ぐ。スライド体１１の出水側の一端には鎖合端塊１１１があり、内部には貫通孔１１２があり、スライド体１１と内部で繋がり一体となり、出水の通路を形成する。
スライド体１１がスライド移動する時に、水流の流動を制御することができるように、スライド体１１の両端にパッキング１６を配置しスライド移動後の水漏れを防ぐ。入水および出水時のスライド移動が迅速に行なわれるように、鎖合端塊１１１の外側にスプリング１７を被せる。スプリング１７の役割は、出水が止まり、高圧水流が還流した時に、迅速にスライド体１１を入水の封鎖をする位置に戻し、同時にポンプが加圧するのを止める。
機械がオフされた時、スプリング１７は即時に水道の中圧または低圧の水流が入水するのを防ぎ、管路が低圧で、噴射ノズルの出口が水漏れしない状態を確保する。バルブ１０の出水側の一端に貫通した放圧バルブ口が配置され、その内部には低圧力のスプリング２１が配置され、放圧口の閉鎖をつかさどるプラグ２２を押し込める。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a pressure relief part according to an embodiment of the present invention. FIG. 2 is a perspective view showing a pressure relief part according to an embodiment of the present invention. FIG. 3 is a cross-sectional view showing a pressure release seat (closed state) according to an embodiment of the present invention. FIG. 4 is a cross-sectional view showing the flow state of water entering and discharging water from the pressure release seat according to an embodiment of the present invention. FIG. 5 is a cross-sectional view illustrating a state in which the water pressure of the refluxed high-pressure water flow is released according to an embodiment of the present invention.
In the pressure relief structure of the present invention, the assembly type slide body 11 is first attached to the hollow tubular valve 10, and then the plug 13 and the spring 14 are attached to the flow hole 12 inside the slide body 11.
The circulation hole 12 has a T shape and is inside the slide body 11. The plug 13 and the spring 14 close the flow hole 12 at appropriate times to control the water flow. A conical hard plastic plug 15 is attached to one end of the slide body 11 on the water inlet side to close the water inlet. There is a chain end lump 111 at one end of the slide body 11 on the water discharge side, and there is a through hole 112 inside, and the slide body 11 is connected to and integrated with the inside of the slide body 11 to form a water discharge passage.
Packing 16 is disposed at both ends of the slide body 11 to prevent water leakage after the slide movement so that the flow of the water flow can be controlled when the slide body 11 slides. The spring 17 is put on the outside of the chain end lump 111 so that the sliding movement at the time of entering and exiting water can be performed quickly. The role of the spring 17 is to quickly return the slide body 11 to the position where the incoming water is blocked when the water discharge stops and the high-pressure water flow returns, and at the same time, the pump stops pressurizing.
When the machine is turned off, the spring 17 instantly prevents the mid- or low-pressure water stream from entering the water, ensuring that the line is low pressure and the outlet of the injection nozzle does not leak. A pressure relief valve port penetrating at one end of the water discharge side of the valve 10 is disposed, and a low pressure spring 21 is disposed inside the valve 10 to push in the plug 22 that controls the closure of the pressure relief port.

高圧噴霧管路の装着は、本考案のバルブ１０をポンプの出水口に直接装着することがポイントである。バルブ１０内の還流した高圧水流が入水を止めると、ポンプの加圧操作が中止され、全システムの安全性が確保される。
使用時においては、高圧水流がポンプからバルブ１０内に入れられると、まず高圧水流はスライド体１１全体をバルブ１０の底部押し込み、鎖合端塊１１１の円錐面とバルブ１０内部とを結合させ密閉状態にする。高圧水流はバルブ１０の中空部に流れ込み、続けてスライド体１１の流通孔１２から流れ込み、バルブ１０内部を閉鎖しているプラグ１３を押し開け、水流をプラグ１３の表面の溝１３１を通して迅速に噴射ノズルに連結する管路に流れ込み、最後に各噴射ノズルにより噴霧されるという完全な高圧噴霧システムが形成される。噴霧が停止されると、高圧水流はバルブ１０内に還流するが、その後、バルブ１０の内圧が上昇し、鎖合端塊１１１の外側にあるスプリング１７の弾性が迅速にスライド体１１を入水側の一端に押し込み、同時に入水口を封鎖し、ポンプの出水操作をオフにする。還流した高圧水流は、閉鎖しているプラグ２２を押し上げ、バルブ１０の側面に配置された放圧バルブ口により内部の高圧を迅速に放圧する。
プラグ２２を押し上げる圧力は主にスプリング２１によるもので、その圧力値は常に低めに設定されており、一般的に約２kgf/ｃｍ２ぐらいで、還流した高圧水流が放圧されて、設定されている圧力になった時、自動的にプラグ２２が封鎖され、バルブ１０全体の圧力も低圧の状態で維持され、全システムの送水管路の内圧は極めて低く維持され、噴射ノズルが水漏れを起こすことはなくなる。再び入水が行なわれると、バルブ１０内部は既に低圧状態にあるため、迅速に加圧を行ない噴霧操作ができ、水流がバルブ１０内部を満たし加圧する時間を必要としない。 The point of installing the high-pressure spray line is that the valve 10 of the present invention is directly attached to the water outlet of the pump. When the refluxed high-pressure water flow in the valve 10 stops entering water, the pressurizing operation of the pump is stopped, and the safety of the entire system is ensured.
In use, when a high-pressure water flow is introduced from the pump into the valve 10, the high-pressure water flow first pushes the entire slide body 11 into the bottom of the valve 10, and the conical surface of the chain end lump 111 and the inside of the valve 10 are joined and sealed. Put it in a state. The high-pressure water flow flows into the hollow portion of the valve 10, then flows from the flow hole 12 of the slide body 11, pushes open the plug 13 closing the inside of the valve 10, and quickly jets the water flow through the groove 131 on the surface of the plug 13. A complete high-pressure spraying system is formed in which it flows into a line connected to the nozzle and is finally sprayed by each spray nozzle. When the spraying is stopped, the high-pressure water flow returns to the valve 10, but then the internal pressure of the valve 10 rises, and the elasticity of the spring 17 outside the chained end lump 111 quickly causes the slide body 11 to enter the water inlet side. At the same time, block the water inlet, and turn off the pump water operation. The refluxed high-pressure water stream pushes up the plug 22 that is closed, and quickly releases the internal high pressure by the pressure relief valve port arranged on the side surface of the valve 10.
The pressure that pushes up the plug 22 is mainly due to the spring 21, and the pressure value is always set to a low value. Generally, the pressure value is set to about 2 kgf / cm 2 , and the high-pressure water stream that has circulated is released. When the pressure reaches a certain pressure, the plug 22 is automatically sealed, the pressure of the entire valve 10 is maintained at a low pressure, the internal pressure of the water supply line of the entire system is kept extremely low, and the injection nozzle causes water leakage. Things will disappear. When the water is introduced again, the inside of the valve 10 is already in a low pressure state, so that the pressure can be quickly applied and the spray operation can be performed.
