EXPLOSION-PROOF SPHERICAL HEAD

摘要

An explosion-proof spherical head comprises: a spherical head body (100), a valve body (200), and a pressure relief unit (500). The spherical head body (100) is provided with a water path and a drainage hole (130) penetrating through the interior to exterior of the water path. The water path has a water inlet (110) and a water outlet (120). The valve body (200) is provided with a water inlet channel (210) and a water outlet channel (220) that are independent of each other, and is connected in the spherical head body (100). The water inlet channel (210) is a part of the water path. One port of the water outlet channel (220) is communicated with the water outlet (120), and another port of the water outlet channel (220) is communicated with the drainage hole (130). The pressure relief unit (500) is connected in the valve body (200) and at least comprises a sealing member (520) and an elastic member (530) pressing against the sealing member (520) to enable the sealing member (520) to seal a port of the water outlet channel (220). When a shower head is blocked, pressure relief can be performed through the pressure relief unit (500), so as to reduce the pressure borne by a shower head body, and achieve the objective of protecting the shower head. In addition, the structure of the spherical head is simple and the cost is low.
