Embodiment
Below by embodiment also in conjunction with the accompanying drawings, technological scheme of the present invention is further described in detail.
Embodiment:
Adjustable pressure release/holding valve as shown in Figure 1, valve body 1 is a right angle threeway, is made up of upper valve body and horizontal valve body, and horizontal valve body has the screw 17 of a setting pressure table by the water intake direction, by the water outlet direction one next door 16 is arranged, directly flow to water outlet from water intake in order to stop medium.There is an osculum c with horizontal valve body axis oblique upper valve body and horizontal valve body joint by the water outlet direction in next door, so that medium is communicated with water intake and water outlet behind valve open.Conical bore a has been sent out at the middle part of horizontal valve body; Slide in the valve opening of upper valve body and joining regulating sleeve 3, sending out between fitting surface has O-ring seals 1, and it can move up and down with regulating sleeve 3, in case medium leaks; Spacing back-up ring 8 has been sent out on upper valve body top, and the adjusting height that restriction regulating sleeve 3 makes progress is when regulating sleeve 3 transfers to the extreme higher position, the shaft shoulder in tool stage casing just in time contacts with the lower end surface of back-up ring 8, limit it and continue upwards, this moment spring 4 the setting height(from bottom) maximum, rigidity is minimum.Otherwise, when locking nut 10 and handwheel 5 when being adjusted downward to extreme lower position, the setting height(from bottom) of spring 4 is the shortest, the rigidity maximum; Poppet shaft 2 is installed in the central authorities of regulating sleeve 3, its center line is consistent with the center line of upper valve body, on 1/2nd length of the axostylus axostyle of poppet shaft 2 upper ends, is carved with two triangular grooves in diametric(al), the gas-tight phenomenon of top cavity volume when moving to eliminate it improves the sensitivity of motion.The upper end cunning of poppet shaft 2 fits among the pilot hole d of regulating sleeve 3, and the axostylus axostyle cunning of its lower end fits in the pilot hole of guide plate 14, can slide up and down along the upper valve body center line at free state lower valve core axle 2.The stage casing of poppet shaft 2 is provided with cone plug b, and its tapering is identical with the tapering of the conical bore a at horizontal valve body middle part, and spool b middle part is provided with O-ring seals 2 11; Spring 4 skies are enclosed within on the axostylus axostyle of poppet shaft 2 upper ends, one end is located on the shoulder of spool b, and the other end is located on the end face of respective interior bores of regulating sleeve 3, and certain pre compressed magnitude is arranged after the assembling, therefore, spring 4 has a thrust that makes spool b press to taper hole a all the time; The internal thread of handwheel 5 and the external thread rotary of upper valve body lump together, and the endoporus of its upper end next door central authorities slides on the axostylus axostyle of regulating sleeve 3 upper ends, and with back-up ring one 6 location, so during handwheel 5 rotations, regulating sleeve 3 can and then not rotate, and can only move up and down.Can clockwise or rotate counterclockwise handwheel 5 according to different cracking pressures, adjust and finish back locking nut 10 lockings.All rolled straight burr on the excircle of handwheel 5 and locking nut 10.There is a lug below at horizontal valve body middle part, is screwing bottom 12 in the lug, and the top of bottom 12 is provided with guide plate 14, guide plate 14 usefulness back-up rings 2 15 location, and sealing gasket 13 leaks in order to prevent medium.
Working principle of the present invention:
When intake pressure did not reach cracking pressure, the conical surface of spool b had been pressed under the pressure of spring 4 on the conical surface of valve opening a, at this moment, valve closing, O-ring seals 2 11 seals, and prevents dielectric leakage; When hydraulic pressure reaches or during greater than cracking pressure, high-pressure medium overcomes the pressure of spring 4, promote poppet shaft 2 and move up, spool b leaves valve opening a, valve open, high-pressure medium flows out from water outlet through gap between the two and inclined hole c.Like this, in water system, can prevent the rapid rising of pressure and damage pipeline and equipment or keep pressure of supply water stable.Improve if desired or reduce cracking pressure, after unscrewing locking nut 10, clockwise or rotate counterclockwise handwheel 5 to correct position and get final product, because the change of spring setting height(from bottom), its rigidity is also change thereupon of cracking pressure.The cracking pressure value when water outlet has the water ejection, can be read from pressure gauge after feeding high pressure water.After adjusting end, must lock with locking nut 10.
