First, detailed materials of the product [the relying on oneself type regulating valve of automatically controlled temperature ]: Type of the products: ZZWPE Name of product: Relying on oneself type regulating valve of automatically controlled temperature Characteristic of the products: ZZWPE automatically controlled temperature regulating valve of relying on oneself etc. (suitable for heavy-calibre and heat conduction oil control relatively), this greatest characteristic of valve only needs ordinary 220V power, utilize the one's own energy of medium adjusted , implement to steam , steam , hot oil and gas temperature of medium automatic controlling directly, can also use preventing from to the overheated or hot exchange occasion , this valve is of simple structure, easy to operate, it is wide that select the temperature adjustment range for use, the response time is fast, the sealing property is reliable , and can regulate at will in running , therefore apply to the hot water supply of such departments as the chemical industry , petroleum , food , light textile , hotels and restaurants ,etc. extensively. Characteristic of the products: This series of products nominal coherent foot-path to 200mm, nominal pressure have 1.0 - 1.6 - 4.0 , 6.4MPa from 20, use temperature range from- 20 copies of 350 degrees Centigrade, accept the signal and come to change the flow of medium adjusted for 00mA.DC or 40mA.DC , make and is accused of the craft parameter keeping in setting value , among them the regulating type of the single seat is suitable for pressing difference smaller, medium viscidity is bigger or has a particle impurity occasion slightly. Greater occasion that the regulating type of the collet is suitable for pressing difference.

( 2) The temperature adjustment valve should be vertical and mounted on horizontal pipeline, the medium should point to unanimity with the arrow point on the body of the valve while flowing into. ( 3) For make automatic control system or can run in succession still at overhauling valving , should set up the by-pass valve , must install the filter in front of the valve, the manometer, installed and examined counting warmly near the sensor , monitor and establish with temperature at the convenient scene. See the picture below: ( 4) Sensor must all submergenc of accusing of the medium , in competence or slope and install upwards. (1)Before installation , check whether the part of the complete machine is flawed or damaged and became flexible , should be washed the pipeline, the medium should point to unanimity with the arrow point on the body of the valve while flowing into. (2)Is it install in is it advise and bump into light place to shake , when conducting oneself with dignity amount relatively heavy valve having to try one's best, there should be regular support frames. Should consider that easy to operate in the installation place , favorable to maintenance again. (3)In order to make the automatic control system can still run in succession when not working or overhauling the valve, should set up the manual valve of the bypass . Overhaul and at using manual valving , should close valve , and then stop valve first. (4)Warm bag all submergenc in transfer into medium , in competence or slope and install upwards (5)The crooked radius of the capillary can't be smaller than 75mm, place it in the natural state, forbid folding or twisting. (6)To facilitate monitoring establishing with temperature at the scene, should set up the manometer with inserting the position and setting up the thermometer in the warm bag in front of the valve, operate the system of installing live |
