Abstract
The utility model discloses a static pressure stabilizing valve, comprising a main body, a regulating seat, a regulating rod and a compression spring. The main body has a liquid inlet and a liquid outlet, in the center of which is provided with a shut-off plug; the regulating seat fixed to the liquid outlet on the main body has a regulating hole corresponding to the shut-off plug; the regulating rod with pipe shape is installed in the regulating seat, and its end trough the regulating hole is opposite to the shut-off plug; the compression spring is covered on the regulating rod, and two ends of it are pressed to the hole edge of the regulating hole and the flange of the regulating rod, respectively, so that between the inner end of the regulating rod and the shut-off plug is maintained a gap by the restoration function of the compression spring. 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.
Description
Technical field
The utility model relates to the technical field of control valve, refers in particular to a kind of quiet pressure maintaining valve.
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 quiet 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:
Quiet pressure maintaining valve mainly is made up of body, adjustment seat, adjustable lever and pressure spring; Body has liquid entering hole and liquid outlet, and the center of liquid outlet is provided with the fluid stopping plug; Adjustment seat is fixedly connected on the liquid outlet of body, and corresponding fluid stopping plug forms adjustment hole in the adjustment seat; Adjustable lever in a tubular form, adjustable lever is nested with in adjustment seat, and to pass adjustment hole relative with the fluid stopping plug in the inner of adjustable lever, is liquid sealing between adjustable lever and the adjustment seat; Pressure spring is enclosed within on the adjustable lever, and the two ends of pressure spring are against respectively on the flange of the peritreme of adjustment hole and adjustable lever, makes retention gap between the inner of adjustable lever and the fluid stopping plug by the reset response of pressure spring.
Be provided with seal ring between above-mentioned adjustable lever and the adjustment seat.
The center of above-mentioned body has pillar, forms circulation liquid road between the inwall of pillar and body, and the fluid stopping plug is fixed on the pillar.
The liquid entering hole of above-mentioned body connects a universal joint, to make quiet pressure maintaining valve easy for installation, has versatility.
After adopting said structure, the utility model is installed in sanitaryware by body and adjustment seat and other requires in the fluid pipeline equipment of working pressure.When the liquid outflow pressure of quiet pressure maintaining valve is less than or equal to setting value, the gap maximum between the inner of adjustable lever and the fluid stopping plug, the utility model does not play regulating action; When the liquid outflow pressure of quiet pressure maintaining valve does not seal greater than setting value and fluid pipeline equipment, utilize the hydraulic pressure of adjustable lever outer end, adjustable lever is moved in adjustment seat, automatically regulate the inner of adjustable lever and the gap between the fluid stopping plug, thereby control the liquid outflow pressure of quiet pressure maintaining valve, reach pressure stabilization function, functions such as assurance sanitaryware are normal, avoid causing mechanism's permanent damage because of pressure jump; When the liquid outflow pressure of quiet pressure maintaining valve during greater than setting value and the sealing of fluid pipeline equipment, utilize the hydraulic pressure of adjustable lever outer end, adjustable lever is moved up to the adjustable lever outer end support fully in adjustment seat to fluid stopping beyond the Great Wall, make between the inner of adjustable lever and the fluid stopping plug being closed shape, thereby the static pressure of controlling quiet pressure maintaining valve within the specific limits.

Fig. 2 is dynamic pressure phase diagram of the present utility model;
Fig. 3 is static pressure phase diagram of the present utility model.
Embodiment
As shown in Figure 1, be the preferred embodiment of the quiet pressure maintaining valve of the utility model announcement, mainly form by body 1, adjustment seat 2, adjustable lever 3 and pressure spring 4.
Body 1 has liquid entering hole and liquid outlet.In order to make quiet pressure maintaining valve easy for installation, have versatility, connect a universal joint 5 on the present embodiment liquid entering hole.The center of liquid outlet is provided with fluid stopping plug 11, the material that this fluid stopping plug 11 can adopt rubber etc. to have seal action is made, for the ease of fixing of fluid stopping plug 11, present embodiment has pillar 12 at the center of body 1, form circulation liquid road 13 between the inwall of pillar 12 and body 1, fluid stopping plug 11 is fixed on the pillar 12.
Pressure spring 4 is enclosed within on the adjustable lever 3, and the two ends of pressure spring 4 are against respectively on the flange 31 of the peritreme of adjustment hole 21 and adjustable lever 3, and makes retention gap A between the inner of adjustable lever 3 and the fluid stopping plug by the reset response of pressure spring 4.
When the utility model is installed, be to be installed in sanitaryware by body 1 (or joint 5) and adjustment seat 2 to require in the fluid pipeline equipment of working pressure with other.
When the liquid outflow pressure of quiet pressure maintaining valve was less than or equal to setting value, as shown in Figure 1, hydraulic pressure did not need to regulate, the reset response of spring 4 by compression, and the gap maximum between the inner of adjustable lever 3 and the fluid stopping plug 11, the utility model does not play regulating action.
When the liquid outflow pressure of quiet pressure maintaining valve does not seal greater than setting value and fluid pipeline equipment, as shown in Figure 2, hydraulic pressure needs to regulate, adjustable lever 3 is subjected to the hydraulic pressure of its outer end and moves in adjustment seat 2, automatically regulate the inner of adjustable lever 3 and the gap between the fluid stopping plug 11, thereby control the liquid outflow pressure of quiet pressure maintaining valve, reach pressure stabilization function, functions such as assurance sanitaryware are normal, avoid causing mechanism's permanent damage because of pressure jump.
When the liquid outflow pressure of quiet pressure maintaining valve during greater than setting value and the sealing of fluid pipeline equipment, as shown in Figure 3, adjustable lever 3 is subjected to the hydraulic pressure of its outer end and moves in adjustment seat 2, support to fluid stopping plug 11 fully up to adjustable lever 3 outer ends, make between the inner of adjustable lever 3 and the fluid stopping plug 11 being closed shape, thereby the static pressure of controlling quiet pressure maintaining valve within the specific limits.
The utility model is that the liquid outflow pressure that utilizes the elastic force of pressure spring 3 to control quiet pressure maintaining valve is set, and utilizes adjustable lever 3 to slide in adjustment seat 2 to regulate the liquid outflow pressure and change within the specific limits.
