Self-reliance type temperature control pneumatic valve using descriptive information < / div >

self-reliance type temperature control pneumatic valve can automatically without external energy, temperature control is widely used in domestic hot water, heating, air conditioning and heat exchange occasion and chemical industry, textile, printing and dyeing, pharmaceutical and other production process, applicable medium can be steam, hot water, hot oil, cooling water, chilled water, etc.


self-reliance type temperature control pneumatic valve working principle is introduced:
thermal fluid expansion shrinkage caused by the temperature variation. At higher temperatures, the thermal fluid expansion, promote executing agency action, will adjust the pneumatic valve pneumatic valve down, reduce heat medium flow; On the other hand, the temperature falls, feeling turbid liquid contraction, took the original spring push regulating pneumatic valve pneumatic valve reverse action, open the pneumatic valve, increases heat medium quality traffic, so as to realize the secondary water temperature and stable in set range.

self-reliance type temperature control pneumatic valve parts is introduced:




self-reliance type temperature control pneumatic valve assembly instructions:

1. Will adjust the pneumatic valve pneumatic valve body part of the protection of the casing is removed ( Large diameter pneumatic valves) 。
2。 Actuator must be perpendicular to the ground during installation.
3。 Temperature 40 ℃, the sensor will be pleasing to the pneumatic actuator on the valve body. When installation to push actuator pneumatic valve body parts, insulation support completely and pneumatic valve body contact, use 4 mm hexagon wrench tight support ( In figure 1 (5) To ensure the actuators are not loose.

self-reliance type pneumatic valve temperature control instructions:

1. Before products leave the factory has been in accordance with the requirements of the users and USES set temperature, the user after close beside the pathway, can directly use this product.
2。 Suggest open PI order: first open the circulation pump, make whole heated water system is increased. Stay close to set temperature, all the open by the pneumatic valve.
3。 Initial enabled, temperature fluctuations, can be used for a short-term operation, can achieve stable working condition. Temperature indicating standard on this product card for factory set temperature, we request for the user to adjust the reference, it does not represent the actual temperature and actual temperature to the scene of the thermometer readings shall prevail.
4。 If there is any deviation in the use of temperature or the user needs to change the set temperature, can be adjusted. Insert the adjusting spanner (sliding temperature knob In figure 1 (1)) Adjust the hole, from low to high temperature adjustment anticlockwise when adjustment at lower temperature, will adjust the wrench clockwise.
5。 System to stop running, turn off heat medium imported by the pneumatic valve, then close system circulating pump.
( Note: this product can not be used as pneumatic valve, the system stops running, HTM pipeline must be turned off by the pneumatic valve. ）

self-reliance type temperature control pneumatic valve common troubleshooting methods:

1. Pneumatic valve spool is action: will support wire loosen, remove the bracket the part above, with the hand down activity core rod, observe whether activities freely. If stuck,
reinforcement with a little oil, slight rotation pneumatic valve rod, can, until I can move to install the control part.
2。 Controller is not action: mother will stand united to loosen and remove the controller, after waiting for system temperature drop down down to adjust the temperature knob, observe whether the plunger. Plunger start can stop adjustment after the activity, install the control part. After normal working temperature can be adjusted according to the demand value.
3。 : beyond set temperature to low temperature regulation is invalid, according to the above two steps to check, if all normal, then shut down regulate before back by pneumatic valve, pneumatic valve check by-pass line
heat medium leakage.
4。 Below the set temperature, the temperature regulation is invalid, will support wire loosen and remove the actuator, pneumatic valve core rod to the service to the highest position, make the hot medium quality all inflows.

warm prompt: this information is only applicable to our factory for temperature control of pneumatic valve.
