Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
A kind of automatic drainage valve as shown in Figure 1, comprise valve body 1, valve body 1 middle part is provided with valve seat 12, valve seat 12 middle parts are provided with the shoulder hole 121 that connects valve seat 12 both ends of the surface, shoulder hole 121 outsides, be distributed with four spilled water holes 122 along valve seat 12 center circumferential, valve seat 12 is separated into valve body 1 cavity of two tubuloses, be respectively water-inlet cavity 13 and water chamber 14, in the outer mold surface of 1 two ends of valve body, be equipped with the taper pipe thread of 55 °, so that valve body 1 is arranged in pipeline, adopt taper pipe thread can play the effect of sealing simultaneously, prevent that medium from leaking outside.
In water-inlet cavity 13, be provided with spool 2, spool 2 is made up of valve rod 21 and valve block 22, valve rod 21 is provided with Compress Spring 3, the two ends of Compress Spring 3 are fixedly connected on respectively on the end face of valve block 22 and the step surface of shoulder hole 121, valve rod 21 extend in water chamber 14 through the shoulder hole 121 on valve seat 12, the end that is positioned at the valve rod 21 of water chamber 14 is provided with pin hole 211, in pin hole 211, be provided with cotter pin 4, make spool 2 can be under the effect of water-inlet cavity 13 interior pressure mediums along the action that reciprocatingly slides of shoulder hole 121 elasticity on valve seat 12, the diameter of valve block 22 is greater than the circumscribed diameter of spilled water hole 122 taking valve seat 12 centers as the center of circle on valve seat 12.In the time there is no medium in water-inlet cavity 13 or only have a small amount of medium, Compress Spring 3 supports spool 2, make whole drain valve in channel status, thereby a small amount of medium in water-inlet cavity 13 can flow out to outflow drain valve in water chamber 14 smoothly, under the logical medium state of water-inlet cavity 13, effect lower compression spring 3 at pressure medium is compressed, spool 2 moves until valve block 22 is blocked the spilled water hole 122 on valve seat 12 to valve seat 12 together with Compress Spring 3, stop medium outflow, after medium has led to, pressure medium disappears, Compress Spring 3 is replied, drain valve automatically restores to again channel status, drain valve has just been realized the function of automatic opening-closing under different operating state like this.
The inwall of the valve body 1 of water-inlet cavity 13 ingress is provided with annular groove 11, in annular groove 11, be fixed with annular back-up ring 5, back-up ring 5 cross sections are circular, are provided with opening 51 on back-up ring 5, so that back-up ring 5 is installed on valve body 1, one end of the back-up ring 5 of water-inlet cavity 13 inside is provided with filter screen 6.Back-up ring 5 mainly plays filter screen 6 is fixed on to the effect on valve body 1, and filter screen 6 can filter the water entering in water-inlet cavity 13, and it is stuck while causing spool 2 reciprocating action that the impurity in anti-sealing enters water-inlet cavity 13 inside, affects the flexible action of spool 2.
Be exactly more than a kind of structure and action effect of automatic drainage valve, its advantage is: simple in structure, and can thoroughly solve pipeline internal water accumulation and arrange sordid problem.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
