Abstract
The utility model relates to a differential pressure bypass valve regulation mechanism capable of not generating incrustation, belonging to the technical field of gas stove equipment. The differential pressure bypass valve regulation mechanism mainly comprises a pressure regulation rod, an iron spring and a valve core, wherein the lower end of the pressure regulation rod is connected with the valve core, the pressure regulation rod is provided with a pressure regulation rod boss, the valve core is provided with a valve core boss, the iron spring is installed between the pressure regulation rod and the valve core, the upper end of the iron spring is contacted with the pressure regulation rod boss, and the lower end of the iron spring is contacted with the valve core boss. The differential pressure bypass valve regulation mechanism has a simple, compact and reasonable structure; and with the adoption of the differential pressure bypass valve regulation mechanism, the pressure regulation rod and the valve core are made of engineering plastics, so that the incrustation is prevented from forming on the valve core, the service life is prolonged, the maintenance cost of a gas stove is reduced, and use is environment-friendly and saving.
Description
Technical field
The utility model relates to a kind of not incrusted differential-pressure bypass valve controlling mechanism, belongs to the gas range equipment technical field.
Background technique
At present both at home and abroad gas combustion wall hanging stove, solvation and the factors such as dipole effect and dissolved oxygen of all not considering water in the stove in the differential-pressure bypass valve design of stove of landing, copper spool and irony spring can produce battery chemistries and react during actual motion.Because copper spool, copper pressure adjusting lever directly contact with the irony spring; Constitute the loop and produced the galvanic couple electric current; Make the iron molecule of the lower irony spring of electrode potential lose iron ion that electronics becomes to the higher copper spool of electrode potential, the migration of copper pressure adjusting lever; Accelerated the oxidation reaction of irony spring, the hydroxyl in iron ion and the water generates iron hydroxide.Because the flocculation of iron hydroxide, the impurity in the cohesion water and separating out forms incrustation scale on copper spool, spool tripping when serious, the differential-pressure bypass valve that makes gas range lost effect and report to the police, self-locking.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Thereby a kind of not incrusted differential-pressure bypass valve controlling mechanism is provided; Pressure adjusting lever and spool all adopt engineering plastics to make, and on spool, can not form incrustation scale, have prolonged working life; Reduced the gas range maintenance expenses, helped environmental protection and economize on resources.
According to the technological scheme that the utility model provides, a kind of not incrusted differential-pressure bypass valve controlling mechanism mainly comprises pressure adjusting lever, irony spring and spool, and said pressure adjusting lever lower end connects spool.Said pressure adjusting lever is provided with the pressure adjusting lever boss, and spool is provided with the spool boss.Said irony spring is installed between pressure adjusting lever and the spool, and its upper end contacts with the pressure adjusting lever boss, and its lower end contacts with the spool boss.
Said pressure adjusting lever lower end is provided with directed cavity, and the upper end of spool is installed in the directed cavity of pressure adjusting lever and can be free to slide.
Said pressure adjusting lever side is provided with the seal ring mounting groove, and the O RunddichtringO is installed in the seal ring mounting groove.
Said pressure adjusting lever and spool all adopt engineering plastics to make.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Pressure adjusting lever and spool adopt engineering plastics to make, and prevent on spool, to form incrustation scale, have prolonged working life; Reduce the gas range maintenance expenses, used environmental protection and saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-pressure adjusting lever, 2-O RunddichtringO, 3-irony spring, 4-spool, 5-directed cavity, 6-pressure adjusting lever boss, 7-spool boss, 8-seal ring mounting groove.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, the utility model mainly comprises pressure adjusting lever 1, irony spring 3 and spool 4, and said pressure adjusting lever 1 lower end connects spool 4.Said pressure adjusting lever 1 is provided with pressure adjusting lever boss 6, and spool 4 is provided with spool boss 7.Said irony spring 3 is installed between pressure adjusting lever 1 and the spool 4, and its upper end contacts with pressure adjusting lever boss 6, and its lower end contacts with spool boss 7.
Said pressure adjusting lever 1 lower end is provided with directed cavity 5, and the upper end of spool 4 is installed in the directed cavity 5 of pressure adjusting lever 1 and can be free to slide.
Said pressure adjusting lever 1 side is provided with seal ring mounting groove 8, and O RunddichtringO 2 is installed in the seal ring mounting groove 8.
Said pressure adjusting lever 1 all adopts engineering plastics to make with spool 4; Engineering plastics have insulating property (properties), can not produce electrochemical reaction with irony spring 3, can on spool 4, not form incrustation scale; Stopped gas range and lost effect warning, self-locking because of producing incrustation scale on the differential-pressure bypass valve; Prolonged the working life of differential-pressure bypass valve, reduced the gas range maintenance expenses, helped environmental protection and economize on resources.
