Abstract
The utility model discloses a pressure reducing valve of a water purifier. The pressure reducing valve comprises a seal cover, a valve body, an upper valve cover, a lower valve cover, a main spring, a reset spring, a valve core and a spring gland, wherein the valve core comprises a circular rod and a conical plug; a hollow cylindrical bulge structure sleeved with an O-shaped ring is arranged at the upper end of the lower valve cover; and a circular hole is formed in the center of the lower end of the seal cover. The valve core and the reset spring are fixed better, so that the pressure reducing valve can control the pressure reducing effect more accurately, the pressure reducing valve of the whole water purifier is simple in structure and excellent in pressure reducing effect, and can be popularized and used widely.
Description
Technical field
The utility model relates to a kind of reduction valve, especially a kind of water purifier reduction valve.
Background technique
Reduction valve is by adjusting, and inlet pressure is reduced to the outlet pressure of a certain needs, and relies on the energy of medium itself, makes outlet pressure keep stable valve automatically.From hydromechanical viewpoint, reduction valve is the throttle element that a kind of local resistance can conversion, and changes orifice size, and the kinetic energy of flow velocity and fluid is changed, and causes the different pressure losses, thereby reaches the purpose of decompression.Rely on the adjusting of control and regulating system then, stirring with spring force of downstream pressure balanced each other, make downstream pressure keep constant within the specific limits.Reduction valve is widely used in industry-by-industry, for example water purifier now.Reduction valve can effectively be controlled the amount of flow of water in the water purifier.
Existing water purifier reduction valve generally exists the problem of effect of easing stress difference.
The model utility content
The purpose of this utility model is in order to improve the problem of water purifier reduction valve effect of easing stress difference.
In order to overcome the above problems, the utility model provides a kind of water purifier reduction valve, comprise sealing cover, valve body, bonnet, bottom flange, main spring, Returnning spring, spool, spring capping, described spool comprises round bar and conical plug, described valve body is divided into valve chamber and lower valve chamber, be provided with control hole between two valve chambers up and down, described control hole lower wall chamfering, the described valve chamber of going up is communicated with water outlet, described lower valve chamber is communicated with water intake, described valve body upside is provided with sealing cover, described sealing cover comprises lid and the seal ring that is fixed on the lid, and the described sealing cover outside is provided with bonnet, and described bonnet top is equipped with spring capping by screw thread, be provided with main spring between described spring capping and the sealing cover, described sealing cover downside and round bar offset, and described control hole downside is provided with conical plug, and described conical plug lower end is with Returnning spring, described Returnning spring lower end and bottom flange offset, and described bottom flange upper end is provided with the hollow cylinder protruding structure that an outside is with O type circle.
Center, described sealing cover lower end is provided with circular hole.
Described conical plug lower end is cylindric.
A kind of water purifier reduction valve described in the utility model, comprise sealing cover, valve body, bonnet, bottom flange, main spring, Returnning spring, spool, spring capping, described spool comprises round bar and conical plug, described valve body is divided into valve chamber and lower valve chamber, be provided with control hole between two valve chambers up and down, described control hole lower wall chamfering, the described valve chamber of going up is communicated with water outlet, described lower valve chamber is communicated with water intake, described valve body upside is provided with sealing cover, described sealing cover comprises lid and the seal ring that is fixed on the lid, the described sealing cover outside is provided with bonnet, described bonnet top is equipped with spring capping by screw thread, is provided with main spring between described spring capping and the sealing cover, and described sealing cover downside and round bar offset, described control hole downside is provided with conical plug, described conical plug lower end is with Returnning spring, and described Returnning spring lower end and bottom flange offset, and described bottom flange upper end is provided with the hollow cylinder protruding structure that an outside is with O type circle.Current enter lower valve chamber by water intake, and owing to conical plug stops up the control mouth, current can not enter valve chamber rapidly, flow out from water outlet fast, but have been slowed down flowing velocity, and flow out from water outlet the back that reduces pressure.Water purifier reduction valve described in the utility model has stable and outstanding effect of easing stress, can promote widely.
