2. Wire port adapter should use standard wrench uniform force tighten, not with afterburner rod afterburner slide wire to make the union, slippery edge and fracture, and to regularly check, in order to avoid causing loose off the plate or seepage.
3. taking into account the problem of aging of rubber products, so in sunny outdoor or wind pipe should build shade frame, non-exposure, rain, wind erosion is necessary.
4. Before installation, the pipeline must be based on the operating pressure, connections, media and the amount of compensation to select the right model, the number of noise displacement according to the requirements of selection.
5. Note the pressure regulator, when a momentary pressure and the conduit should be greater than the operating pressure is higher than the working pressure of a selection of gear joint.
6. Note that reusable hose fittings under pressure in the first, for example, after installation or long-term disabled before compression is enabled again, it should be re-pressurized and tighten the bolts again put into operation.
7. attention to its temperature regulation, normal for the media is 0-60 degrees Celsius temperature in ordinary water, special media.
8. When the pipe displacement greater than or equal to the maximum amount of compensation joints, should increase the number of joints to parallel displacement, non-tolerance in order to adjust the pipeline, in flexing the joint displacement and deviation from state limit, but can not exceed the limit .
9. The top water or floating water pipes should be fixed in the hanger bracket or anchor shelves and does not allow the joint to bear its own weight and axial force pipeline, or joints should be equipped with anti-pull-off device.
Accordingly, since the hose connector has a good overall performance, it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial development in different areas, fire, etc.

Residual pressure valve works?

Residual pressure valve works?
Residual pressure valve can be used in clean room or clean room, indoor and outdoor used to maintain a positive pressure, excess air from the room, to prevent outside air intrusion.
How it works: When the pressure exceeds the standard purification room pressure, valve gate automatically opens when the pressure is lower than the standard, the valve closed state recovery, to balance the pressure. Internal air pressure to prevent the purification room squeeze caused by the noise and the possibility of a burst. Residual pressure valve manifold types There are many different applications have different nuances, welcome to inquire details residual pressure valve.
Residual pressure valve characteristics
1. Installation in the form of a wall-mounted, wall thickness within 30 ~ 50mm can be adjusted.
2. Hammer position can be adjusted according to the amount of wind, pressure requirements.
3. Surface paint or electrostatic spray (spray color is generally white, can also be specified by the user). If other requirements should be stated in the order, according to the user's needs, and manufacture of various specifications. And generally use a differential pressure gauge. Can be custom made according to size.
4. In order to prevent contamination of clean rooms, indoor positive pressure must be maintained, if the clean room pressure is too high, causing the doors easy switch, thus the use of pressure relief dampers to keep the positive pressure clean room. Air flow through the pressure relief damper is generally between 100-1200m3 / h, maintaining the pressure differential between 5-40Pa.

What is the role of the expansion valve? It works?

What is the role of the expansion valve? It works?
The electronic expansion monoblock valves is a new throttle device, which is controlled by a microprocessor, it appears to achieve a computer direct control and regulation of the refrigeration cycle. Electronic expansion valve and stepper motor type solenoid type two structural forms . Strictly speaking, the electromagnetic coil is a solenoid-type expansion valve. Now we are talking about the current electronic expansion valve usually refers to the stepper motor type. It consists of the valve body, valve, bellows, transmission and pulse stepper motor and other components. Pulse stepper motor drive mechanism, the bellows is a refrigerant passage with moving parts separated to prevent refrigerant leaks. Role of the drive mechanism is rotary motion of the motor into reciprocating motion of the spool. There are two kinds of transmission, gear transmission mechanism includes gear pairs, rib pairs, such as the transmission lever. Direct-acting actuator no gear pair.
Characteristics of electronic expansion valve to regulate large-scale, rapid and sensitive action, adjust precision, stable and reliable. The refrigerant in the electronic expansion valve can be positive, the reverse flow in both directions, avoiding the disadvantages of only one direction of the thermal expansion valve. Refrigeration system can be greatly simplified for the heat pump when. The cooling system is down, the electronic expansion valve can be completely closed, so that no need to install the refrigerant inlet solenoid valve.

Sequence valve works it?

Sequence valve works it?
How it works:
According to the working principle and structure, sequence valve direct-acting and pilot sub-type categories; by pressure control mode, the sequence valve has internal and external control of the points. In the sequence valve installed in a one-way valve, can be called a reverse flow check valve composite sequence valve. Generally, the valve use more.
Functions and applications:
The basic function is to control the sequence hydraulic valve block actuators multiple sequential actions, depending on their functions, called sequence valve, back pressure valves, relief valves and balancing valves. Relief sequence valve performance and essentially the same, but because of the different functions of the sequence valve as well as its special requirements:
(1) In order to achieve accurate actuator action sequence, the order requires high precision pressure regulator valve, the deviation is small;
(2) the accuracy of the order of actions in order to require a small amount of leakage within the aluminium valves is closed;
(3) For one-way sequence valve, pressure loss and requires reverse positive pressure loss values should be compared with the school
       The main role of sequence valve are:
(1) controlling the operation sequence of the plurality of elements;
(2) for packing loop;
(3) to prevent the weight of the free-fall and cause cylinder piston do with balancing valves;
(4) with external control sequence valves do unloading valves, pump unloading;
(5) with internal sequence valve for back pressure valve.
