no. 1 example

[0037] Such as Figure 1 to Figure 3 As shown, the present invention discloses a waterproof hammer pressure reducing valve, which includes an upper cover 1, a bottom cover 2 matched with the upper cover 1, an adjusting piece 3 and an adjusting spring 4 located in the upper cover 1 and the bottom cover 2; wherein The adjusting piece 3 is oriented to move between the upper cover 1 and the bottom cover 2 through a guide mechanism;

[0038] Specifically, the upper cover 1 includes a cavity 10, the upper part of the cavity 10 is a baffle 12 provided with a water inlet, and the side part is an annular side wall 11, and the bottom and bottom of the side wall 11 are Cover 2 thread fit.

[0039] Cooperate figure 1 , the regulating piece 3 is a funnel-shaped structure whose diameter tapers from top to bottom inwardly, and a water hole 31 is formed in the middle; the diameter of the outer edge of the regulating piece 3 is smaller than the inner diameter of the side wall 11 of the upper...

no. 2 example

[0050] Cooperate Figure 10 and Figure 11 , in the second embodiment of the present invention, the difference from the first embodiment is that the diameter of the outer edge of the adjusting piece 3 is the same as the inner diameter of the side wall 11, so there is no protruding portion 32, and the adjusting piece 3 There are several through-holes 33 around the center of the water hole 31 on the periphery, and the through-holes 33 form the auxiliary flow channel 5; the water flow can flow through the auxiliary flow channel 5 formed by the through-hole 33, and the water flow can also be adjusted. purpose of the area.

no. 3 example

[0052] Cooperate Figure 12 and Figure 13 , in the third embodiment of the present invention, the difference from the first embodiment is that the guide mechanism is a guide protrusion 34 and a guide groove that cooperate with each other formed between the adjustment piece 3 and the side wall 11 of the upper cover 1 14. The guide protrusions 34 and the guide grooves 14 are at least two groups; the guide protrusions 34 and the guide grooves 14 can also control the directional movement of the adjusting piece 3 .

[0053] Specifically, the adjusting piece 3 extends outwards to guide the protrusions 34, and the side wall 11 of the upper cover 1 forms a guiding groove 14 inward; there is a certain gap between the adjusting piece 3 and the side wall 11 of the upper cover 1 to form a The auxiliary flow channel 5 is described.

[0054] Of course, it is also possible that the adjusting piece 3 forms a guide groove 14 inwardly, and the side wall 11 of the upper cover 1 forms a guidin...

Abstract

The invention discloses a water hammer prevention pressure reducing valve which comprises an upper cover, a bottom cover matched with the upper cover, an adjustment sheet located between the upper cover and the bottom cover, and an adjustment spring, wherein an accommodating cavity is formed in the upper cover; the upper part of the accommodating cavity is a stopping edge with a water inlet; the side surface of the accommodating cavity is an annular side wall; a water passing hole is formed in the middle part of the adjustment sheet; an auxiliary runner is formed on the outer side of the water passing hole; the adjustment sheet moves in a fixed direction between the upper cover and the bottom cover through a guide mechanism; a plurality of water outlets are formed in the bottom cover; connection bars are arranged between the water outlets; a stopping pillar connected with the water passing hole in the adjustment sheet in a sleeving manner is upwards formed in the middle of the bottom cover; an inclined stopping surface which is inwards narrowed gradually extends upwards from the stopping pillar; and the adjustment spring is arranged between the adjustment sheet and the bottom cover. Through the adjustment sheet, the adjustment spring, the inclined stopping surface and the stopping pillar, the water hammer prevention pressure reducing valve controls a water passing area and reduces water impact energy so as to control the water discharging flow and the flowing speed; and therefore, the 'water hammer effect' is well eliminated, and the service lives of a pipeline and the valve are guaranteed.

Description

technical field [0001] The invention relates to a water industry product, in particular to an anti-hammer pressure reducing valve implemented at a pipe joint. Background technique [0002] In our daily water environment, if the water pressure of the pipeline is relatively high, when we open or close the waterway, there will be a "water hammer effect", that is, the hydraulic force will reach the maximum quickly, and a large instantaneous pressure will be generated on the pipeline or valve. , this instantaneous pressure can reach dozens or even hundreds of times the normal working water pressure in the pipeline. This large pressure fluctuation can cause strong vibration or noise in the pipeline system, and may damage the valve joints and pipelines, which has a great destructive effect on the pipeline system. Contents of the invention [0003] The object of the present invention is to provide an anti-hammer pressure reducing valve implemented at the pipe joint, which can eff...
