Description

Hydraulic all-round pressure changer

The utility model relates to a kind of hydraulic pressure transformer, particularly relates to a kind of waterpower all-round pressure changer.It is that second putting chamber of matrix is located at a side into water flow passage and outlet passage, end section sidewall is provided with discharge opening, the indoor sleeve edge top of inserting the Decompression valves device that makes is provided with commentaries on classics baric flow road and outlet passage intercommunication, the bottom be provided with the pressure release runner can with go into the water flow passage intercommunication, when the hydraulic pressure in the outlet passage is increased to the pressure that sets greater than regulator, high pressure water liquid promptly presses valve stage casing small diameter part up to pass commentaries on classics pressure valve from changeing the baric flow road through changeing, so that separating with valve collar, the bottom valve plug opens path, so, going into water liquid in the water flow passage can change by the pressure release runner and flow out from discharge opening through the valve collar endoporus, and it is more smooth and easy to reach the pressure release that makes the waterpower transformer in view of the above.

See also Figure 10, shown in Figure 11, the structure of traditional high pressure relief valve 70 includes an axis body 71 substantially, its front end is installed with a pressure release pin 72, the rear end then is provided with a spring 73, its periphery movable body 74 that is pivoted again, axis body 71 hypomeres are provided with water outlet 711, and epimere is provided with the water intake 712 that water outlet 711 is connected, on movable body 74 precalculated positions, be provided with two-screw member 741 in addition, hydraulic pressure withstands movable body 74 below borrowing at ordinary times, as shown in figure 10, it is close proximity on the pressure release pin 72, so as to blocking water intake 712, when the place ahead hydraulic pressure is excessive, promptly can as shown in figure 11 movable body 74 be promoted downwards, make water intake 712 expose, water supply enters and is discharged by water outlet 711, reaches the purpose of pressure release, is closed and work as water outlet 711, top hydraulic pressure is during less than rear pressure, and movable body 74 can be pushed back original position again water intake 712 is closed.

Said structure is continued to use for a long time, but has following defective at least:

(1) if contains foreign material in the current, for example be present in the particle in the agricultural operation, or the senile abrasion fragmentation of O type rubber ring 75 etc., because of it all has viscosity, very easily be stuck on the axis body 71, and movable body 74 can't be pressed closer in pressure release pin 72 again, that is can't close water intake 712 fully, cause whole Decompression valves 70 will lose effectiveness.

(2) movable body 74 knee-action repeatedly very easily makes two-screw member 741 produce loosening phenomenon.

Main purpose of the present utility model is, overcome the defective of prior art, and provide a kind of waterpower all-round pressure changer, make it change the parallel tail end of being located at outlet passage in baric flow road, when the hydraulic pressure in the outlet passage is increased to the pressure that sets greater than regulator, can raises rapider, smoothly to change and press valve.

Of the present utility model time a purpose is, a kind of waterpower all-round pressure changer is provided, and makes discharge opening wherein be located at the nearly bottom of second putting chamber, is promptly going into the tail end of water flow passage, and water liquid can be flowed out from discharge opening swimmingly, and expedite misgivings.
