first, u11sm / f-type internal thread plunger valve structure and working principle
by the valve body, valve cover, stem, plunger, hand wheel and other components. when the handwheel is rotated, the plunger is driven by the valve stem so that it reciprocates up and down between the two sealing rings to complete the opening and closing of the valve.
because the sealing ring is made of a new, very metallic material (ptfe), it withstands long-term high temperatures and pressures without loss of elasticity and has a large contact area between the plunger and the sealing ring. furthermore, the performance of the sealing ring-based mixed material is good therefore, the seal is reliable and durable.
second, u11sm / f-type thread plunger valve : the scope of application
the valve is suitable for metallurgy, fire protection, chemical industry, construction, fertilizer, light industry and other industries, the pressure is 1.6-4.0mpa, the temperature is below 250 ℃ water, gas, oil and other media pipeline.
