を低下させてしまうなどの不都合があつた。 2. Description of the Related Art A device shown in FIG. 1 has been known as a device for removing oxide scales used in hot rolling of steel sheets. This removing device M has a large number of injection nozzles 1' arranged above and below the rolled material m, and high-pressure water (generally 150
Kg/cm 2 ) is sprayed, and the force of the spray removes the scale. In this case, the pressurized water reaches the injection nozzle 1' through the main pipe 30, but when the main valve 31 (spool valve) is closed and the water supply is stopped when the work is completed, the water flows from the injection port of the injection nozzle 1'. When air enters the main piping and then the main valve 31 is opened to supply water, a water hammer phenomenon occurs because the air is trapped inside the main piping 30, and the violent impact causes various parts to burst and explode. Accidents of damage occur. Therefore, as a measure to prevent this accident, conventionally,
As shown in FIG. 1, low-pressure water (30 kg/cm 2 ) was constantly supplied through an auxiliary pipe 32, and this low-pressure water was dripped from the injection nozzle 1' to prevent air from entering. However, this conventional method not only has the big problem of wasting water because it is constantly dripping, but also has a negative impact on the product because it needs to be constantly dripping even during work that does not require spraying. There were disadvantages such as deterioration of quality due to

圧力水噴射ノズル弁を提供することにある。 The present invention was made to solve these conventional problems, and its purpose is to provide the injection nozzle itself with a valve function so that when the main valve closes, the injection nozzle automatically closes. By closing the valve and preventing the inflow of air from this injection nozzle, the occurrence of water hammer phenomenon is prevented, and the opening and closing operation is performed using the water pressure accompanying the opening and closing of the main valve. An object of the present invention is to provide a pressure water injection nozzle valve which can be automatically opened and closed without using any special power and has a simple structure.

作動しないようにする。 Next, when the main valve is opened during the rolling operation, pressure water flows from the main pipe into the nozzle valve A, and the water pressure of this pressure water causes the poppet valve 18 to close to the spring 2.
1, the valve part 19a is separated from the seat 20, the flow path D is opened, and the injection port 16 at the lower end is pushed down.
Pressure water is ejected from the press to remove scale generated on the surface of the rolled material. When the main valve is closed upon completion of the work, the pressure inside the nozzle valve A decreases, and the elastic force of the spring 21 pushes the poppet valve 18 up to the state shown in FIG. is brought into pressure contact with the sheet 20 to hermetically close the flow path D and prevent air from flowing in from the injection port 16, thereby making it possible to prevent the water hammer phenomenon caused by air remaining in the main pipe. In addition, in order to deal with an unexpected accident in which the seal between the valve part 19a and the seat 20 is damaged and air inflows, low-pressure water is constantly supplied from the auxiliary pipe as in the case shown in Fig. 1 to prevent leakage. The spring 21 may be made to have a resilient force greater than the pressure of the low-pressure water so that the poppet valve 18 will not operate under the pressure of the low-pressure water. .

ンマー現象による破裂や破損を防止できる。 As explained above, according to the present invention, the injection nozzle itself has a valve function, which prevents the inconvenience of air flowing in from the injection nozzle when the water supply is stopped, thereby preventing water hammer. It can prevent rupture and damage due to phenomena.
又、圧力水の水圧を利用して弁を開放させるの

う効果を奏する。 In addition, since the valve is opened using the pressure of pressurized water, there is no need to use a separate device to open and close the valve.
Moreover, it has the effect of simplifying its structure.

Since the pressure water flowing into the flow path D is drawn into the flow path from the flow hole by the force of the pressure water flowing through the flow path D, the pressure of the pressure water does not act in the opposite direction to push up the poppet valve. Not only can the poppet valve be stabilized, but it also has the effect of preventing dirt and the like from accumulating in the space.
