Negative pressure rubber connector is a rubber joints to resist suction, when the external pressure is greater than the internal pressure(rubber joint head/soft joint rubber shock absorber), laryngeal.
1.Negative pressure resistant rubber joint rubber made ofdifferent materials can be made resist to Acid and alkali, corrosion, oil, heat and a variety of media and the environment.
2.Rubber joint material is a polar rubber, rubber joint is sealing well and light weight, rubber joint installation is Convenient. It has long service life it shall avoid contact with sharp metal instruments, so as not to puncture the rubber ball joint.
3.Rubber joints installed overhead can use elastic support, rubber joint installation installaion shall be bolted by diagonal Method of tightening.
4.Rubber joints used on high pressure pipe line shall be connected with limit bolts at both ends of the flange.
5.Rubber joint flange connection adopt the GB4216.3-4216.5 standard, otherwise shall be specified separately.
The working pressure of the product Grade 0.6Mpa,1 Mpa,1.6 Mpa,2.5 Mpa.
The use of negative pressure ball can be used in vacuum to avoid the sphere deformation and damage.
