Abstract
The utility model discloses a porous sleeve-type waterpower control pressure-reducing valve which comprises a valve body, a valve cover connected with the valve body, membranes arranged in the valve body and the valve cover and a valve core and flap control device, wherein a water inlet end of the valve body is communicated with a membrane upper cavity via a throttle valve, a water outlet end of the valve body is communicated with the membrane upper cavity via a pressure-reducing pilot valve, a perforated sleeve barrel is also arranged in the valve body, and the valve core and flap control device is positioned in the sleeve barrel. The utility model has the advantages that vapor etched resisting capability is strong due to that the installation of the perforated sleeve barrel causes water which flows through a valve to collide mutually for dissipating energy, meanwhile, air bubbles which are formed as a result of high pressure difference are pushed toward the center of the porous sleeve barrel, then the air bubbles break up, and gas etching is reduced, the working pressure difference is large, the pressure difference of a common waterpower control pressure-reducing valve is within 7 kg/cm <3>, but the pressure difference of the valve can achieve 30 kg/cm <3>, the mode of control is simple, the reliability is high, and the life time is long.
Description
Technical field
The utility model belongs to the waterpower reduction valve, is specifically related to the waterpower control reduction valve with pilot-actuated valve.
Background technique
The two-chamber diaphragm type reduction valve that existing market is used, its structure comprises valve body, the valve gap that is connected with valve body, barrier film in the valve body valve gap and valve shaft, flap control gear, the valve inleting water end is communicated with the barrier film epicoele by throttle valve, and the valve body waterexit end is communicated with the barrier film epicoele by the decompression pilot valve.When this valve uses, the flow direction of fluid from right to left, it is little to be suitable for pressure reduction, when the pressure reduction of import and outlet was big, the high pressure water impact valve interior wall formed bubble, forms cavitation erosion, the working life of reduction valve.
Summary of the invention
The purpose of this utility model is to design the porous sleeve formula waterpower control reduction valve of band sleeve in a kind of valve body, to overcome the defective that above-mentioned reduction valve exists.
This reduction valve is: it comprises valve body, the valve gap that is connected with valve body, barrier film in the valve body valve gap and valve shaft, flap control gear, the valve inleting water end is communicated with the barrier film epicoele by throttle valve, the valve body waterexit end is communicated with the barrier film epicoele by the decompression pilot valve, also be provided with the sleeve of perforate in the valve body, valve shaft flap control gear places sleeve.This valve has following advantage: changed the flow direction of fluid, the flow direction of fluid from left to right; The anti-cavitation ability is strong, collides energy dissipating mutually because of the sleeve of perforate being installed, having been made the flow through water of valve, and simultaneously, the bubble that forms because of High Pressure Difference is pushed to the middle cardiorrhexis of porous sleeve, has reduced cavitation erosion; Use pressure reduction is big, and the pressure reduction of general waterpower control reduction valve is at 7kg/cm
3Within, and the pressure reduction of this valve can reach 30kg/cm
3Control mode is simple, the reliability height; Long service life.

Embodiment
As shown in Figure 1, establish valve seat 2 between the water intake 20 of valve body 1 and the water outlet 21, valve gap 13 is connected with valve body 1, establish barrier film 10 in the valve gap 13, diaphragm 10 is passed in valve shaft 4 upper ends, and the lower end connection which is provided with top board 6, press table 3, the flap 7 of seal ring 5, sleeve spring 8 on the valve shaft 4, and flap 7 contacts with valve seat 2.Sleeve 14 with flap 7 and valve shaft 4, spring 8 covers within it.Offer hole 15 and relative in twos on the wall vertically of sleeve 14, sleeve 14 separates valve inleting water mouth 20 and water outlet 21, and the valve inleting water end is communicated with barrier film epicoele 19 by throttle valve 16, and valve body waterexit end 17 is communicated with barrier film epicoele 19 by decompression pilot valve 18.
The decompression principle of this valve is as shown in Figure 2: establishing inlet pressure P1, is P if obtain mouth pressure, and the spring force F of pilot valve is adjusted into P, makes F=P.
If actual outlet pressure P2＞P, P2＞F then, diaphragm are upwards, drive chock plug and upwards close pilot valve, then main valve can tend to close, and reduces the water passage hole number, thereby makes water pressure P2 be reduced to setting value P.
If actual outlet pressure P2＜P, P2＜F then, then diaphragm is downward, drives chock plug and is opened to valve downwards, and then main valve can be tending towards opening, and increases piston water passage hole number, thereby makes discharge pressure P2 be increased to the value P of setting.This valve also can subtract static pressure.
Claims (2)
1, a kind of porous sleeve formula waterpower control reduction valve, it comprises valve body, the valve gap that is connected with valve body, barrier film in the valve body valve gap and valve shaft, flap control gear, the valve inleting water end is communicated with the barrier film epicoele by throttle valve, the valve body waterexit end is communicated with the barrier film epicoele by the decompression pilot valve, it is characterized in that also being provided with in the valve body sleeve of perforate, and valve shaft flap control gear places sleeve.
2, porous sleeve formula waterpower control reduction valve according to claim 1 is characterized in that sleeve separates valve inleting water mouth and water outlet, and the hole on the sleeve is axially offered and relative in twos along sleeve wall.
