Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As shown in Fig. 1 ~ Fig. 3,1. valve body, 11. horizontal cavities, 12. air cavitys, 13. water cavities, 14. water ports, 15. spacing interior shoulders, 16. female thread structures, 2. "O"-ring, 3. valve gap, 4. spring, 5. piston, 6. convex, 7. mounting groove is installed.
Water hammer-resistant valve, it is that a kind of being arranged in pipe-line system also effectively can prevent the interior valve mechanism producing water hammer of pipeline, is mainly made up of valve body 1, valve gap 3, spring 4 and piston 5 etc.
Described valve body 1 had both adopted three way valve as shown in Figure 1, also two-way valve body as shown in Figure 3 can be adopted, the present embodiment is described in detail for three way valve, the horizontal cavity 11 and vertical cavity that interconnect in " ┻ " type is provided with in it, the two ends of this horizontal cavity 11 are respectively equipped with water intake and the water outlet of female thread structure 16, so that connect pipeline.
The valve gap 3 that described vertical cavity top is connected by thread seal is closed, the piston 5 that upper and lower activity is installed also is provided with in this vertical cavity, the outer peripheral surface of piston is provided with two pass "O"-ring 2, and two pass "O"-ring is mainly as the dynamic seal of piston 5 seal-moving, they all contact as movable sealing with the inwall of vertical cavity, therefore can be separated into mutual disconnected air cavity 12 and water cavity 13 by vertical cavity respectively according to upper and lower position by piston 5.
Arrange spring 4 in described air cavity 12, this spring upper end is fitted in the default mounting groove 7 of valve gap 3 inner bottom surface, arranges the installation convex 6 for spring 4 upper end portion pushing installation at the bottom land of this mounting groove simultaneously; This spring 4 lower end is also fitted in the mounting groove 7 that piston 5 end face presets, and simultaneously arranges the installation convex 6 for spring 4 underpart pushing installation at the bottom land of this mounting groove, therefore piston 5 under normality possesses all the time by the elasticity pushing tow of spring 4 and moves downward driving force.
