The anti-exploding protection device comprises a U-shaped structure, a pressure plate, locking screws and nuts. The height of the U-shaped structure is equal to the external diameter of a valve body of the protected PPR stop valve, the width of the top end of the U-shaped structure is equal to the external diameter of the valve body of the protected PPR stop valve, the locking screws are respectively welded to the middle parts of two tops ends of the U-shaped structure, the middle parts of two ends in the length direction of the pressure plate are respectively provided with a small round hole, the central part of the pressure plate is provided with a larger round hole, the locking screws penetrate through the small round holes of the pressure plate respectively, and the nuts are arranged at the upper ends of the screws to enable the pressure plate and the U-shaped structure to be connected to be a whole. The anti-exploding protection device for the PPR stop valve solves the problems met with in production, and the protection device formed by utilizing the prior art and materials guarantees safety of devices and workers and smooth running of production. The product is firm, durable, convenient to use and remarkable in protection effect.
Description
Technical field
The utility model relates to a kind of flame proection, particularly a kind of PPR stop valve flame proection.。
Background technique
In actual use, the service condition difference of PPR plastic stop valve, the pressure that the gland of PPR plastic stop valve and valve seat connection part are subjected to has nothing in common with each other, and the material quality of valve is also inequality, the aged deterioration time can not determine, occurs the valve seat fault that pops easily.
PPR stop valve in actual the use, when waterpipe uses, need higher hydraulic pressure owing to produce, and the hydraulic pressure that water utility carries is on the low side, just need install supercharging device additional at the water main line, the pressure that bears of the gland of PPR stop valve and valve seat will be a lot of greatly like this; If the PPR stop valve is used on the feed channel, the pressure that the gland of PPR stop valve and valve seat bear will increase 2～3 times.According to above two kinds of situations, add plastic article and wear out easily, be easy to take place the danger that the PPR stop valve pops.Can cause the damage of equipment and personnel's injury.Therefore need solve the problem that runs in the use of PPR stop valve according to a kind of flame proection of the autonomous processing of field condition, assurance equipment and personnel's safety ensures carrying out smoothly of producing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of flame proection of PPR stop valve, satisfies the security needs of equipment and personnel in the actual production.
For the purpose that realizes solving the problems of the technologies described above, the utility model has adopted following technological scheme:
The flame proection of a kind of PPR stop valve of the present utility model comprises U-shaped structure, pressing plate and locking screw, nut; Wherein:
The height of U-shaped structure is identical with the valve body outer diameter of protected PPR stop valve, and the top width of U-shaped structure is identical with the valve body outer diameter of protected PPR stop valve; Locking screw is two, is welded on the intermediate portion, two tops of U-shaped structure respectively, uses as locking;
Intermediate portion, pressing plate length direction two ends respectively arranges a small sircle hole that can pass locking screw, and the centre distance of two small sircle holes is identical with the locking screw centre distance of U-shaped structure top welding;
The pressing plate center portion arranges big hole, and the big hole diameter is fit to PPR valve gland extending area and passes;
Locking screw passes the small sircle hole on the pressing plate respectively, in the screw rod upper end nut is set pressing plate and U-shaped structure are connected as a single entity.
Concrete, the flame proection outer surface of PPR stop valve of the present utility model arranges the plating armour metal layer.Armour metal layer can be zinc coat, nickeling layer or chromium coating.Working life that like this can extension fixture.
Further concrete, the flame proection of PPR stop valve of the present utility model, the diameter of described small sircle hole are 8.5mm.
The processing method of the PPR stop valve flame proection of model utility is: at the PPR stop valve of different tube diameters, flame proection different length, width and thickness of material; Material is used galvanized steel plain sheet, for the PPR stop valve of D20, D25 and D32, selects width 30mm for use, the galvanized steel plain sheet of thickness 3mm; The U-shaped structure length cuts according to different valves with pressing plate length, and pressing plate length exceeds U-shaped structure width 30mm; For D40 and above PPR stop valve, use width to be 50mm, thickness is the galvanized steel plain sheet of 5mm.
By adopting technique scheme, the utlity model has following beneficial effect:
The flame proection of the PPR stop valve of this patent has solved the problem that runs in producing, and the protective gear that utilizes prior art to become with materials processing has guaranteed equipment and personnel's safety to have guaranteed carrying out smoothly of production.Product is durable, and is easy to use, and the protection effect is remarkable.

Embodiment
Further specify this patent below in conjunction with accompanying drawing.But the protection domain of this patent is not limited to concrete mode of execution.
To shown in Figure 4, the flame proection of a kind of PPR stop valve of this patent is made of U-shaped structure 7, pressing plate 4 and locking screw 5 as Fig. 1.U-shaped structure 7 is inserted in from the valve below; remove valve handle; pressing plate 4 is inserted in from the valve top; two root beads that the small sircle hole 2 of both sides is inserted in U-shaped structure 7 connect on the screw rod 5; circular hole 3 broad in the middle is enclosed within on the gland 8, with nut 1 pressing plate 4, U-shaped structure 7 and valve is tightened, and the gland 8 of valve is locked on the valve base by pressing plate 4 and U-shaped structure 7 like this; can not throw off fully, play the protective action that is perfectly safe.
