Abstract
The utility model discloses a dynamic pressure stabilizing valve, comprising a main body, a regulating rod and a spring. The main body has a liquid inlet, a liquid diverting port and a liquid outlet located between the inlet and the outlet. Between the inlet and the outlet also forms a regulating seat intercepted with the liquid path. One end of the regulating seat is closed and the other end is an open end, between which and the liquid diverting port is provided with a connecting pipe. In the regulating seat is arranged with the spring and the regulating rod, between which and the regulating seat is sealed at liquid state. A through hole is provided corresponding to the liquid path in the main body on the regulating rod, which could communicate the through hole with the liquid path by the restoration function of the spring and could deviate the through hole from the liquid path to regulating the hydraulic pressure to get a stabilized pressure by the glide in the regulating seat induced by the hydraulic pressure at the liquid diverting port. The utility model applicable to the toilet and bathroom products or other liquid pipeline equipment working in pressure could guarantee the normal function of the toilet and bathroom products and the avoidance of the permanency destruction of the configuration induced by the jump in pressure.

Background technique
At present, most of sanitaryware and some fluid pipeline equipment all have certain requirement to working pressure on the market, when intake pressure is excessive, just must have a decompressor to control, otherwise its function just can't guarantee, even may cause this mechanism to produce permanent damage.
The inventor is at this requirement to working pressure of sanitaryware and other fluid pipeline equipment, specialized designs a kind of voltage stabilizing control valve, this case produces therefrom.
The model utility content
The purpose of this utility model is to provide a kind of moving pressure maintaining valve, and it applies to sanitaryware and other requires can guarantee stability hydraulic in the fluid pipeline equipment of working pressure.
In order to achieve the above object, the technical solution of the utility model is:
Moving pressure maintaining valve, mainly by body, adjustable lever and spring are formed, body has liquid entering hole, split-flow opening and liquid outlet, split-flow opening is between liquid entering hole and the liquid outlet, also form the adjustment seat of intersecting between liquid entering hole and the split-flow opening with the liquid road, the one end sealing of this adjustment seat, the other end is uncovered, and be provided with connecting tube between uncovered and the split-flow opening, be provided with adjustable lever and spring in the adjustment seat, be liquid sealing between adjustable lever and the adjustment seat, the liquid road of corresponding body offers through hole on the adjustable lever, adjustable lever makes through hole communicate with the liquid road by the reset response of spring, and slide in adjustment seat by the hydraulic pressure of split-flow opening and to make through hole depart from the liquid road regulating hydraulic pressure, reach pressure stabilization function.
Above-mentioned adjustment seat is vertically set on the liquid road of body.
Set up an oil hydraulic cylinder between the uncovered and connecting tube of above-mentioned adjustment seat, be provided with piston in the oil hydraulic cylinder, the push rod of piston is connected on the adjustable lever, and piston end face is towards connecting tube.
Be provided with seal ring between above-mentioned adjustable lever and the adjustment seat.
Above-mentioned spring is a pressure spring, and closed end, the other end that an end of spring is against adjustment seat are against on the adjustable lever.
After adopting said structure, the liquid entering hole and the liquid outlet of body is connected on the fluid pipeline, is about to that the utility model is installed in sanitaryware and other requires in the fluid pipeline equipment of working pressure.The utility model utilization shunting pressure difference is to the variation of adjustable lever pressure, promoting adjustable lever moves in adjustment seat, change the degree that through hole departs from the liquid road, the flow area of body is changed, regulate the hydraulic pressure of liquid outlet, reach pressure stabilization function, can guarantee that functions such as sanitaryware are normal, avoid causing mechanism's permanent damage because of pressure jump.
Description of drawings
Fig. 1 is original state figure of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is adjustment state figure of the present utility model;
Fig. 4 is the partial enlarged drawing of Fig. 3.
Embodiment
As shown in Figure 1, be the preferred embodiment of the moving pressure maintaining valve of the utility model announcement, mainly form by body 1, adjustable lever 2 and spring 3.
Body 1 has liquid entering hole 11, split-flow opening 13 and liquid outlet 12.Split-flow opening 13 is between liquid entering hole 11 and the liquid outlet 12, also form the adjustment seat 14 of intersecting between liquid entering hole 11 and the split-flow opening 13 with liquid road 15, adjustment seat 14 is vertically set on the liquid road of body 1 in the present embodiment, so more helps the adjusting of liquid road flow area.The one end sealing of this adjustment seat 14, closed end can be covered by end cap 16 and realize sealing on adjustment seat 14, and the other end of adjustment seat 14 is uncovered, and is provided with connecting tube 17 between uncovered and the split-flow opening 13.Be provided with adjustable lever 2 and spring 3 in the adjustment seat 14.Be liquid sealing between adjustable lever 2 and the adjustment seat 14, present embodiment is to be provided with seal ring 18 between adjustable lever 2 and adjustment seat 14, realizes liquid sealing.Spring 3 is a pressure spring, and closed end (being end cap 16), the other end that an end of spring 3 is against adjustment seat 14 are against on the adjustable lever 2.The liquid road 15 of corresponding body 1 offers through hole 21 on the adjustable lever 2.
After the utility model is installed in the fluid pipeline equipment that sanitaryware and other require working pressure, when hydraulic pressure is less than or equal to setting value, cooperate illustrated in figures 1 and 2, adjustable lever 2 is by the reset response of spring 3, make through hole 21 communicate fully with liquid road 15, flow area is maximum, and the hydraulic pressure of liquid outlet 12 equals the hydraulic pressure of liquid entering hole 11, and the utility model does not play regulating action; At hydraulic pressure during greater than setting value, cooperate Fig. 3 and shown in Figure 4, hydraulic pressure by split-flow opening 13, adjustable lever 2 overcomes the reset response of spring 3 and slides in adjustment seat 14, through hole 21 departs from liquid road 15, automatically the flow area of regulating body 1 changes, and the hydraulic pressure of liquid outlet 12 is changed within the specific limits, thereby reach pressure stabilization function.
The utility model is that the pressure that utilizes the elastic force of spring 3 to control liquid outlet 12 is set, and utilize adjustable lever 2 hydraulic pressure of regulating liquid outlet 12 that in adjustment seat 14, slides to change within the specific limits, guarantee that thus functions such as sanitaryware are normal, avoid causing mechanism's permanent damage because of pressure jump.
More accurate in order to regulate, present embodiment is also set up an oil hydraulic cylinder 5 between the uncovered and connecting tube 16 of adjustment seat 14, be provided with piston 51 in the oil hydraulic cylinder 5, and the push rod 52 of piston 51 is connected on the adjustable lever 2, and the end face of piston 51 is towards connecting tube 16.Like this, when regulating, the hydraulic pressure of split-flow opening 13 acts on the end face of piston 51 through connecting tube 16, and the push rod 52 by piston 51 reaches adjustable lever 2 again, thereby reaches the adjusting pressure stabilization function.
