The pull rope switch is also the control device of the fast rolling shutter door switch. Its special feature is that it pulls the rope on the forklift or behind the door to realize the door opening and closing.

  4。 When the screw type injection machine nozzle is used, the hole diameter should be large to prevent dead angle stagnation. No inserts, if any, should be preheated.

The protective safety door is a device used to block or close an area. It is mainly composed of the door body and the door frame. The construction of any building needs the door. With the development of society and the continuous improvement of people's living standard, the manufacturer and designer of the door are constantly improving and innovating on the door. A kind of door is disclosed, including the door frame, door leaf and opening and closing The door leaf is hinged on the door frame, a secondary sealing structure is adopted between the door leaf and the door frame, the door leaf comprises a base body and a heat insulation layer, the opening and closing mechanism comprises a rotating shaft, a connecting flange, a connecting rod and a guide sleeve, the rotating shaft passes through a smooth hole through the door leaf and can rotate in the light hole, and the rotating shaft is threaded connected with the connecting flange at the inner side of the door leaf, and the connecting flange is threaded The upper part is hinged with a connecting rod which passes through the guide sleeve arranged on the door leaf. The door designed in the above technical scheme is mainly used as the door of mine rescue cabin, so as to solve the problems of complex structure, poor sealing and heat insulation effect of the door opening and closing mechanism of the existing mine rescue cabin. It can also be used as the door of cabin and cold storage, with the advantages of simple structure of opening and closing mechanism, good sealing and heat insulation effect.

The fast rolling shutter door is generally used in large-scale industrial workshops. Its firmness and long service life are the reasons why manufacturers prefer to choose. It takes no space and can be fully integrated with the building public, which makes the manufacturers prefer. The fast rolling shutter door is controllable, and the door body is composed of door frame, door leaf, upper and lower rotating shafts, electric bolt, door opener, sealing element, etc. The door switch is controlled by a motor. There is an electric plug in the middle of the door, which can lock the door with the motor. In case of emergency, the door can be opened and closed manually. Therefore, there is a certain guarantee on safety. Moreover, because it is an electric equipment, the single air shower room is much more labor-saving and convenient for the users.

There are not many interlocking devices in the application of fast rolling shutter doors. It is only applicable to the doors with at least two or more high-speed rolling shutter doors. When one fast door is open, the other one will be closed.

  2。 Due to its corrosion and fluidity, special equipment and mould are suitable. All products should be added with different kinds and quantities of additives according to the needs!

With the development of the door frame, the door frame is mainly used to block the door frame in the building, including the door frame The door leaf is hinged on the door frame, and a secondary sealing structure is adopted between the door leaf and the door frame. The door leaf comprises a base body and a heat insulation layer. The opening and closing mechanism comprises a rotating shaft, a connecting flange, a connecting rod and a guide sleeve. The rotating shaft passes through the smooth hole through the door leaf and can rotate in the light hole. The door company is in the inner side of the door leaf, and the rotating shaft is connected with the connecting flange in thread The connecting flange is hinged with a connecting rod which passes through the guide sleeve arranged on the door leaf. Fire proof curtain has high flame retardancy. It is qualified by bt-test of Japan Fire Protection Association and approved by Japanese fire department ae-13-0279. It is suitable for chemical factories and buildings (flame retardant index jisd1201) to prevent wind and dust Overlapped (overlap) installation structure, good air tightness, with the weight of the curtain itself, in adverse weather wind speed, will not reach the degree of bending and affect normal operation. It has non flammability, high strength, weather resistance and excellent geometric stability. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. What conditions should the wind resistant rolling shutter door device meet? 1、 Installation conditions: 1, in the use of wind resistant shutter, if it has a fault, do not remove it privately yo, should find professional staff to solve the problem.

  1。 Amorphous material, less moisture absorption, poor fluidity. In order to improve the fluidity and prevent bubbles, the plastic can be pre dried. The gating system should be short and thick, and the gate section should be large without dead angle. The mould of air shower room must be cooled and the surface should be chrome plated?

Features: excellent mechanical and electrical properties, strong acid and alkali resistance, good chemical stability, insulation layer of wires and cables, sealing elements of air shower chamber, etc.

The function of geomagnetic induction is similar to that of radar, but it is mainly aimed at metal objects. When the wind shower room, such as vehicles, is approaching, the magnetic field of the geomagnetic ring will be induced, and the high-speed door will be opened immediately.

The air bag is the protection device of the fast rolling shutter door. It is the pressure air feeling installed at the bottom of the high-speed rolling shutter door. When the object under the door is pressed in the descending process of the fast door, it will automatically bounce back to the safe height, which is an important guarantee for the safety of the high-speed rolling shutter door.

  3。 Very easy to decompose, at 200 ℃ with steel. Copper contacts are more likely to decompose, and corrosion escapes during decomposition. Irritant gas. Molding temperature range is small!
