Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
A pulse decompression integrated valve is combined with a figure 1-3 and comprises a main valve body 1, wherein a water inlet chamber A and a water outlet chamber B are arranged on the main valve body 1, a middle chamber inlet C1 is arranged between the water inlet chamber A and the water outlet chamber B, and the water inlet chamber A, the middle chamber inlet C1 and the water outlet chamber B are arranged in parallel; the water inlet chamber A is arranged in the center, and the middle chamber inlet C1 and the water outlet chamber B are symmetrically distributed on two sides of the water inlet chamber A. The middle chamber inlet C1 functions to connect the inlet chamber a and the outlet chamber B; 3-5, a vacuum breaker is arranged at the upper end of the middle chamber inlet C1 and is used for controlling the connection and disconnection of the water outlet chamber B and the middle chamber inlet C1; a concentric annular outlet is arranged on the main valve body 1 at the lower end of the middle chamber inlet C1, the inner space of the inner ring is the inlet of the middle chamber inlet C1, and a water inlet chamber outlet A1 is arranged between the inner ring and the outer ring; the concentric ring-shaped outlet is covered with a pulse valve 2, and the on-off of the inner ring space and the outer ring space is controlled by the opening and closing of a pulse valve membrane 2 a.
With particular reference to FIG. 4, the vacuum breaker is arranged as follows: a valve cover 7 with an atmospheric pressure port 3 is arranged at the upper end of the main valve body 1, and two passages are arranged inside the valve cover 7 respectively and are used for communicating the atmospheric pressure port 3 to the upper part of a piston valve plate 11. The piston valve plate 11 is arranged at the joint of the middle chamber inlet C1 and the water outlet chamber B, when water flows through the corresponding middle chamber inlet C1, the piston valve plate 11 overcomes the action of atmospheric pressure to jack up, the atmospheric pressure inlet is sealed, and the middle chamber inlet C1 is communicated with the water outlet chamber B; when the middle chamber inlet C1 is not filled with water, the water inlet pipeline may generate vacuum due to water flow backflow, and at this time, the piston valve plate 11 moves down to cover the water outlet of the middle chamber inlet C1 under the action of atmospheric pressure to avoid water refilling of the water outlet chamber B. The upper end of the piston valve plate 11 is provided with an upper guide frame 12 extending into an atmospheric pressure inlet, and the lower end of the piston valve plate 11 is provided with a lower guide frame 13 extending into an outlet of the middle chamber inlet C1, so that the smoothness of the action of the piston valve plate 11 can be further ensured.
Furthermore, a check valve 8 with a V-shaped top is arranged at the inlet of the water inlet chamber A, and a slit is arranged at the top to play a role in one-way communication. The check valve 8 is matched with the piston valve plate 11, so that double guarantee can be realized, and water backflow of the water outlet cavity B is avoided. The top of the one-way valve 8 is provided with a support column 9, and the support column 9 is supported on the top of the water inlet chamber A in an upward mode to play a role in stabilizing the one-way valve 8.
With reference to fig. 3 and 4, a pressure relief valve 10 is provided between the water inlet chamber a and the water outlet chamber B, so that when the water pressure in the water inlet chamber a is too high, the pressure can be relieved in time, and the safety of the pulse valve 2 is ensured.
As shown in fig. 3, the main valve body 1 is provided with a third outlet 1a at the rear side of the check valve 8, the third outlet 1a is connected with a spray valve body 4 in a hard manner, and the spray valve body 4 is provided with an electromagnetic valve 5 and a pressure reducing valve 6; the opening and closing of the third outlet 1a are controlled through the electromagnetic valve membrane 5a, and the water pressure is controlled through the pressure reducing valve 6, so that the stability of the water pressure at the spray cleaning interface 4a is guaranteed.
