The plunger pump pressure regulating valve is provided with a water inlet and a water return, characterized in that the valve body is a four-way structure, separately connecting with the water inlet, the manual water return, the automatic water return and the crown bar channel, the steel ball on the upper end of the spring arranged in the water inlet is sealing engaged with the lower valve seat of the four-way valve body, the cone valve positioned in the manual water return is sealing engaged with the right valve seat of the four-way valve body, the conical shaft shoulder on the lower end of the crown bar is sealing engaged with the upper valve seat of the four-way valve body, the right valve cavity is communicated with the upper valve cavity via the through-hole. The utility model makes the automatic, manual water return and the pressure regulating function in one body and has pressure stabilization function.
Description
Technical field:
The utility model relates to pressure control equipment, particularly the pressure regulator valve on the plunger pump.
Background technique:
Pressure regulator valve on the used plunger pump of existing high-pressure fog machine generally has automatic backwater function.When in use, if nozzle switch is beaten when half-open or the closed condition, automatically can not aristogenesis hydraulic pressure in the water recovery apparatus, the current stabilization poor performance also causes the too early wearing and tearing of inner body easily.And some simple and easy type is only adorned manual backwater switch, can the fast adaptation variation in water pressure.But because no automatic backwater mechanism, steady flow result is relatively poor.
Summary of the invention:
The utility model provides a kind of and integrates automatically, manually backwater and voltage regulation function and the pressure valve of voltage stabilizing function is arranged.
Solution of the present utility model is: valve body is the four-way structure, connect water intake, manual backwater mouth, automatic backwater mouth respectively, the push rod passage, be arranged on the steel ball of the spring upper end in the water intake and the lower valve base fitted seal of four-way valve body, be arranged on the interior cone valve of manual backwater mouth and the right valve seat fitted seal of four-way valve body, the taper shaft shoulder of push rod lower end and the upper valve base fitted seal of four-way valve body are led to logical by the hole between right valve chamber and the uuper valve chamber.Be positioned at uuper valve chamber push rod position and be shaped on the shaft shoulder, its sectional area is greater than withstanding steel ball one end cross-sectional area.Screw thread is carved with in the push rod upper end, and vestlet and nut are fixedly connected, nut and push rod scyewed joint, and spring housing is outside push rod, and the one end withstands on the vestlet, and an end withstands on the nut, and nut places on the pressure cap; Locating stud is arranged on the push rod; Between pressure cap and the valve body seal ring is arranged, between pressure cap and the depression bar seal ring is arranged, push rod shaft shoulder downside groove is equipped with seal ring, and the spool head has seal ring, between pressure cap and the valve body seal ring is arranged.
By hole link, played voltage stabilizing function between horizontal cavity volume of the manual backwater mouth of the utility model and the uuper valve chamber, realized voltage regulation function by rotation vestlet Regulation spring extending amount, thus automatic backwater.Manually backwater, pressure regulation, voltage stabilizing function are in one.Because manually the elastic coefficient is very little in the backwater spool, so manually pressure of return water is very low, realize the low pressure backwater, reduce energy consumption.Stable working pressure is provided, prolongs atomizing sprayer and sebific duct working life.
Description of drawings:
Fig. 1 is the utility model embodiment's a sectional view.
Embodiment:
With reference to accompanying drawing, pressure spring 17 places in the water intake 22, there is steel ball 19 on its top, upper end, water intake 22 inner chambers top has right valve chamber 23, spool 15 is housed in it, and spool 15 left ends are with seal ring 16, and core chamber Nei Ding has spring 13, pressure cap 11 constitutes the spring seat of spring 13, and its two ends are threaded with valve body 10, manual return pipe 21 respectively.Be equipped with seal ring 14 between pressure cap 11 and the valve body 10, manually on the return pipe 21 hand switch 12 arranged.Right valve chamber 23 tops have duct 20 and are communicated with uuper valve chamber 25.Push rod 4 lower ends are passed pressure cap 6 and are withstood steel ball 19, and push rod 4 positions that are positioned at uuper valve chamber 25 are shaped on the platform shaft shoulder 26, and its section area withstands steel ball 19 1 end section areas greater than push rod 4, and shaft shoulder below has groove, is embedded with seal ring 9 on the groove.Push rod 4 upper ends are shaped on screw thread, and push rod 4 is threaded with nut 2, and vestlet 1 is fixedlyed connected with nut 2, and spring 3 is enclosed within outside the push rod 4, and an end withstands on the vestlet 1, and an end withstands on the nut 27, and nut 27 places on the pressure cap 6, have locating stud 5 to run through push rod 4 between the two.
When press water is entered by water intake 22, steel ball 19 is cooperated with valve body 10 play seal action.Under water pressure, spool 15 is backed down, and opens switch 12 and realizes manual backwater, because the elasticity coefficient of spring 13 is very little, so pressure of return water is very low.Off switch 12, press water enters uuper valve chamber 25 by 20 and forms hyperbaric chamber, this moment, steel ball 19 place cavity volume hydraulic pressure were strong identical by force with uuper valve chamber 25 hydraulic pressure, withstood steel ball one end and were subjected to the hydraulic pressure area, so just produced a pressure difference because of push rod 4 is subjected to the hydraulic pressure water area to be far longer than push rod 4 at uuper valve chamber 25 again, when hydraulic pressure enough big, the pressure that the pressure difference that produces produces greater than spring 3 and spring 17 and, make push rod 4 move down, back down steel ball 19, water is gone out from backwater mouth 24, realize automatic backwater.The decrement of adjusting spring 3 when rotation vestlet 1 produces different pressure, and it is strong to form different hydraulic pressure in uuper valve chamber 25, thereby realizes voltage regulation function.When work, the water pressure size variation directly can reach uuper valve chamber 25, by spring 3 automatically flexible balances, push rod 4 is fluctuated, and realizes voltage stabilizing function.
