Abstract
The utility model discloses an antifouling poppet gas valve, which comprises a valve seat, a bonnet, a bolt, a valve head and a spring. On the top of the valve body, an airflow hole is opened, an antifouling spray-fused coating is arranged on the surface of the valve seat, the bonnet and the airflow hole. The utility model is easy to maintain on the course of using, resulting in avoiding gas running or leakage due to wear, and have an effect of energy conservation and production cost reduction.
Description
Technical field
The utility model relates to the air valve technical field, especially a kind of air valve of the valve head of pestering.
Background technique
At present, the application of air valve and extensive relates to industry such as chemical fertilizer industry, petrochemical industry, mining and metallurgy.The national according to statistics energy that is used for Driven Compressor accounts for 10% of all power station institute generated energy greatly, and because air valve design unreasonable, energy loss accounts for the 15%-20% of compressor shaft power, the design premises of air valve is to work in cleaning ambient at present, when air valve is applied to contain a large amount of dust, in the time of in the complicated gaseous environment such as tar or active carbon, owing to contain a large amount of fouls in the compressed gas, these fouls very easily stick to the surface of air valve runner, cause the air valve wearing and tearing to be accelerated, poorly sealed, become flat, gas leakage is serious, and air valve reduces working life greatly, only is 1/100 of the ideal operation life-span.
Summary of the invention
Goal of the invention of the present utility model for provide a kind of can be under the complicated gas condition that contains fouls such as dust, tar, active carbon proper functioning, it is little to wear and tear, the air valve of long service life.
The technological scheme that realizes the foregoing invention purpose is as follows:
A kind of antifouling bacterium shape air valve comprises valve seat, valve gap, bolt, mushroom valve head and spring, has airflow hole on the valve body, is provided with antifouling sprayfused coating at valve seat, valve cover surfaces and airflow hole internal surface.Between valve seat and valve gap, be provided with locating stud.
Owing to be coated with stain-proofing layer in valve body surface, so airborne dirt is difficult for adhering on the valve body, the wearing and tearing of air valve reduce greatly, simultaneously also solved the problem of deflation, gas leakage, the energy consumption of production process is reduced greatly, energy efficient 3-8%, cost of production descends.And in use be easy to safeguard.By between valve seat and valve gap, locating stud being set, make being connected of valve seat and valve gap more stable, can not cause phenomenons poorly sealed, the air valve wearing and tearing because of displacement takes place reasons such as vibrations.Air valve improves more than 3 times working life.
