Abstract
The utility model relates to the pressure control for the gas and fluid, in particular to a pressure balanced valve provided with a valve body which is respectively provided with an inflow port and an outflow port. The valve body is also provided with a pressure regulation hole whose periphery is connected with the external periphery of an elastic membrane ring whose internal periphery is connected with a pressure regulation plate which is connected with a valve rod whose the other end is provided with a valve core which is matched with the valve body at the inflow port or outflow port to proceed with the pressure regulation to ensure the stable pressure of the inflow port or outflow port. The utility model adopts atmospheric pressure to proceed with the relative control of the pressure in the valve body with the atmospheric pressure, the pressure of the inflow port or outflow port is stable, so the utility model has the advantages of simple structure, low cost, difficult damage, long service life, stable and accurate pressure control, etc.
Description
Technical field
The utility model relates to the pressure control of gas and fluid, specifically a kind of equilibrated valve.
Background technique
As everyone knows, existing various pressure controlled valve all is to use elastic element to set and regulate pressure, also do not use atmospheric pressure to make the pressure controlled valve of control power, use elastic element set and regulate pressure have complex structure, cost height, fragile, working life is short, pilot pressure is unstable, deficiency such as inaccurate.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, long service life, pressure control stable, equilibrated valve accurately.
The utility model can reach by following measure:
A kind of equilibrated valve, be provided with valve body, be respectively equipped with inflow entrance and outflow opening on the valve body, it is characterized in that also being provided with on the valve body pressure regulating hole, the outer periphery of elasticity zona is connected with the periphery of pressure regulating hole, and the inner periphery of elasticity zona is connected with pressure regulator panel, pressure regulator panel is connected with valve rod, the other end of valve rod is provided with spool, and spool matches with the valve body at inflow entrance or outflow opening place and carries out the pressure adjusting, to guarantee the pressure stability of outflow opening or inflow entrance.
The utility model is regulated in order to make, pilot pressure is more accurate, and the area of elasticity zona is greater than the section area of the valve body touching position at spool and inflow entrance or outflow opening place.
In addition, the utility model can be provided with between pressure regulator panel and valve body regulates the elastic element that pressure is used, and realizes other pressure control that controlled chamber is relevant with atmospheric pressure, to enlarge using scope of the present utility model.
The utility model is owing to adopt said structure, adopt atmospheric pressure that the valve body internal pressure is carried out the pressure control relevant with barometric pressure, the pressure stability that keeps inflow entrance or outflow opening has advantages such as simple in structure, with low cost, not fragile, long service life, pressure control are stable, accurate.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
A kind of structural representation when Fig. 1 is the utility model spool formal dress.
A kind of structural representation of Fig. 2 when to be that the utility model spool is counter adorn.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings: a kind of equilibrated valve, be provided with valve body 1, be respectively equipped with inflow entrance 2 and outflow opening 3 on the valve body 1, also be provided with pressure regulating hole 4 on the valve body 1, the outer periphery of elasticity zona 5 is connected with the periphery of pressure regulating hole 4, and the inner periphery of elasticity zona 5 is connected with pressure regulator panel 6, pressure regulator panel 6 is connected with valve rod 7, the other end of valve rod 7 is provided with spool 8, and spool 8 matches with the valve body 1 at inflow entrance 2 places and carries out the pressure adjusting, to guarantee the pressure stability of outflow opening or inflow entrance.
The utility model is regulated in order to make, pilot pressure is more accurate, and the section area of elasticity zona 5 is greater than the section area of spool 8 with valve body 1 touching position at inflow entrance 2 or outflow opening 3 places.
In addition, the utility model can be provided with between pressure regulator panel 6 and valve body 1 regulates pressure with elastic element 9, realizes other pressure control that controlled chamber is relevant with atmospheric pressure, to enlarge using scope of the present utility model.
The utility model is owing to adopt said structure, adopt atmospheric pressure and the pressure relevant that pressure in the valve body is controlled with barometric pressure, outflow opening or inflow entrance pressure stability have advantages such as simple in structure, with low cost, not fragile, long service life, pressure control be stable, accurate.
Working procedure of the present utility model is: 1, during the spool formal dress, as shown in Figure 1, the pressure P of inflow entrance 2
1With barometric pressure P
0Relatively, if P
1≤ P
0, spool is closed, and works as P
1＞P
0The time, spool is opened, P
1The segment fluid flow in chamber flows into P
2The chamber, (P
1＞P
2Condition under), so just make P
1The chamber maximum pressure maintains P
0If spool 8 is compared and can be ignored with the section area of elasticity zona with the section area of valve body 1 touching position at inflow entrance 2 or outflow opening 3 places, the perforate of spool only and P so
1Cavity pressure is relevant, if add the elastic element 9 (as shown in Figure 3) of a pressure regulation between elasticity zona and valve body, can also realize P
1Chamber (inflow) maximum pressure is stabilized in the pressure of another setting; 2, spool is anti-when adorning, and as shown in Figure 2, works as P
2＞P
0The time, spool is closed, and works as P
2＜P
0The time spool open (P
1＞P
2), so just make P
2The minimum pressure in chamber maintains P
0If, between diaphragm and valve body, add the elastic element of a pressure regulation, can also realize P
2The chamber minimum pressure is stabilized in the pressure of some settings.
