The third because of improper assembly or related parts size is not suitable. 。 Offset method is to debug screw tight force, when the screw must be tight at the diagonal form, it is best to tight while surveying space, everywhere to screw tight tight deadline, and make the joint gap is exactly the same everywhere. Additional, media constantly leaking will make hard tightly closed material damage, however, the commonly used pressure release valve tightly closed surface is metal to metal material, is trying to do is bright and clean level off, but in the medium with pressure things do not leak is also very difficult. Second, check repair low-grade, the valve core seat grinding can not meet the quality standards, eliminate the fault is according to the damage degree of thought and the use of grinding or turning right after grinding to repair tightly closed surface. So far using YST103 general steel electrode welding processing of valve core tightly closed surface effect is good. Lead to tightly closed surface damage mainly comprised of the following: one is tightly closed surface material is bad. Because of this, for office medium is steam safety valve, under prescribed pressure value, if in the outlet of the eyes can't see, also don't recognize have leakage, feel is standard strict sealing performance. For example, the tooth profile was tightly closed pad radial small trench, parallelism is poor, such as tooth tip or a slope lack can all result in a tightly closed lose effectiveness. 2. The valve leakage of joint face? Refers to the joint between the upper and lower body surface leakage phenomenon, is mainly comprised of the leakage has the following aspects: one is: on the surface of the joint screw slant tight force is not enough or tight, lead to joint face tightly closed very bad. Three is: the body is the simplest of the joint surface degrees or be hard impurities cushion tightly closed out of validity. Q: relief valve ( The relief valve) The common failures and comprised a: 1. The valve leakage? Under pressure from normal office facilities, disc and seat tightly closed surface occurred more than allow degree of leakage, pressure release Industrial Valves ( The relief valve) The leak of pay will be actuating medium loss. Lead to tightly closed for impurity mat live deprived of, when the Industrial Valves assembly seriously organize joint surface to prevent impurities fall into completely. When check repair the good quality of spare parts, right and use standard tooth tightly closed mat can prevent the occurrence of this phenomenon. If leakage point when trying to find the furnace run after mound exits, estimation is caused by this situation, can be in running tuo cooling after 20 minutes after rudder, the tightly closed surface erosion. The second thing is tightly closed surface damaged condition. The second is: on the surface of the body joint tooth tightly closed pad is not qualified. About the simplest because the body on the surface of the joint surface degrees too bad but the boot body joint leakage, alleviation is Marine valve body of the valve weight until new grinding faying surface meets quality standards. Eliminate this kind of failure is to wipe out a full drop to tightly closed, dirt and impurities on the surface of the ordinary in the boiler to start the furnace volume repairing, first try run exit lead, if found leakage of collapse, check after the furnace repair. So that the body joint leakage. Alleviation is seizing the valve core surrounded by appropriate void volume and the average sex, guarantee top valve core hole with tight sealing faces are degrees, seizing each gap is not allowed to lift the valve core. According to the drawing requirements appropriate reduce successful implementation work tightly closed tightly closed surface width. Common cause of valve leakage comprised mainly has the following three things: 1 kind of thing is: dirt into tightly closed surface impurities, will tightly closed surface mat, cause there are gaps between the valve core and valve seat, so the valve leakage. core seat in the assembly process is not absolutely right or joint surface phenomenon of pervious to light, or is the valve core seat tightly closed surface too wide disadvantages in tightly closed.
