Description
Technical field
The utility model belongs to plumbing technical field, particularly relates to the pressure-limit valve used in a kind of water system.
Background technique
Along with the improvement of people's life, the pressure of supply water rising day by day of water system.But along with the increase of water supply pressure, high hydraulic pressure proposes requirements at the higher level to water system, and the pressure of supply water increased very easily damages water system simultaneously, cause leaking in a large number.Need a kind of scheme to reduce for this reason and limit the hydraulic pressure in water system, ensureing the safety of water system.
Model utility content
The purpose of this utility model is to provide a kind of for the pressure-limit valve in water system, can reduce and limit the hydraulic pressure in the water system of pressure-limit valve water outlet end.
To achieve these goals, the utility model takes following technical solution:
A kind of pressure-limit valve, the valve gap comprising valve body and be connected with described valve body, is provided with axially extended water portion excessively in described valve gap, described water portion of crossing stretches in described valve body, and described water portion is excessively hollow article; Pressure governor is provided with in described valve body, described pressure governor comprises pressure regulator body and sealing gasket assembly department, described pressure regulator body is sheathed on described end, water portion excessively, described sealing gasket assembly department is connected with described pressure regulator body end, described sealing gasket assembly department is provided with and can closes the described sealing gasket crossing water portion, between described sealing gasket assembly department and described pressure regulator body, be provided with water passage hole; Described mistake in water portion is provided with level pressure spring, and one end and the described pressure governor of described level pressure spring are supported, the other end and described valve gap inwall are supported; Described pressure governor can move back and forth described mistake in water portion, makes the water route distance between the modified water portion of described sealing gasket and pressure governor.
Seal ring is equipped with between pressure governor of the present utility model and described valve interior wall, between described pressure governor and described mistake water portion end outer wall.
It is peripheral that water passage hole of the present utility model is positioned at described sealing gasket assembly department.
From above technological scheme, in the inner chamber that the utility model is formed at valve body and valve gap, water portion was set, cross in water portion and pressure governor is set, pressure governor can move by axial reciprocating, when the hydraulic pressure of valve body waterexit end changes, the hydraulic pressure of waterexit end makes setting sealing gasket thereon can change regulator and crosses the size of the distance between water portion, thus the pressure loss that can change pressure governor and cross between water portion, and then the hydraulic pressure of reduction and limiting valve body waterexit end, reach the hydraulic pressure reduced and in restriction water system.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in more detail.
Embodiment
As shown in Figure 1, the pressure-limit valve of the present embodiment comprises valve body 1, valve gap 2, pressure governor 3, sealing gasket 4, level pressure spring 5 and multiple O-ring seals (non-label), and pressure-limit valve of the present utility model is arranged at (water inlet be connected with tap is taken over) in water system.Valve body 1 is connected with valve gap 2, forms the space holding pressure governor 3 and level pressure spring 5.The periphery wall of the connecting end that valve body 1 is connected with valve gap 2 is processed with outside thread, and the inner circle wall of the connecting end that valve gap 2 is connected with valve body 1 is processed with internal thread, and valve body 1 is connected by screw thread with valve gap 2, is sealed and matched between valve body 1 and valve gap 2 by O-ring seals.
Be provided with in valve gap 2 and axially extendedly cross water portion 2a, cross water portion 2a and stretch in valve body 1, crossing water portion 2a is hollow tubular, and the water in water inlet adapter passed through water portion 2a and flows in valve body 1.Pressure governor 3 is arranged in valve body 1, and it was sheathed on 2a end, water portion.Level pressure spring 5 cover was arranged on water portion 2a, and one end and the pressure governor 3 of level pressure spring 5 are supported, the other end and valve gap 2 inwall are supported, and pressure governor 3 can move by axial reciprocating under the elastic force effect of level pressure spring 5 on mistake water portion 2a.O-ring seals is equipped with between pressure governor 3 and valve body 1 inwall, between pressure governor 3 and mistake 2a end, water portion outer wall.
Pressure governor 3 is hollow article, it comprises pressure regulator body 3-1 and sealing gasket assembly department 3-2, pressure regulator body 3-1 was enclosed within water portion 2a, sealing gasket assembly department 3-2 is connected with pressure regulator body 3-1, be positioned at the central authorities of pressure regulator body 3-1, be provided with water passage hole 3a between sealing gasket assembly department 3-2 and pressure regulator body 3-1, it is peripheral that water passage hole 3a is positioned at sealing gasket assembly department 3-2.Sealing gasket 4 is arranged on sealing gasket assembly department 3-2, the size of sealing gasket 4 adapts with the size crossing water portion 2a, when pressure governor 3 moves axially with the pressure change of valve body waterexit end, sealing gasket 4 can change (opened or closed) the water route distance between water portion and pressure governor.
Below the working principle of the utility model pressure-limit valve is described:
Water in water system entered in water portion 2a inner chamber, then entered in pressure regulator body 3-1, then flow to the waterexit end B of pressure-limit valve through the water passage hole 3a of pressure governor 3 after flowing into the feed-water end A of pressure-limit valve.The hydraulic pressure of the waterexit end B of pressure-limit valve can produce pressure to pressure governor 3, level pressure spring 5 also can produce active force to pressure governor 3 simultaneously, under the effect of water pressure and elastic force, there is axial displacement in pressure governor 3, thus the water route distance between water portion 2a and sealing gasket 4 was changed in valve body 1.When valve body waterexit end pressure increase, sealing gasket 4 is in time crossing water portion 2a, and distance diminishes, and pressure governor and the pressure loss crossed between water portion increase, thus are limited by the hydraulic pressure of valve body waterexit end.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the field are to be understood that, still can modify to embodiment of the present utility model or equivalent replacement, and not departing from any amendment of the utility model spirit and scope or equivalent replacement, it all should be encompassed among right of the present utility model.
