Embodiment Construction

[0026] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, the pressure regulator is mainly composed of a body 1, a throttle valve 2, a limit platform 3, a conical platform 4, a positioning seat 5, a spring 6, and a screw 7. The throttle valve 2 further includes a conical body 21, Protrusion 22, valve rod 23, described positioning seat 5 is placed on the limit platform 3, described valve rod 23 passes through the central hole of positioning seat 5 from the outlet end to the inlet end, the screw 7 passes through the spring 6, rotates Tightly on the internal screw hole of valve stem 23. The body 1 is made of plastic, and the outer surface is provided with sealing folds 11 .

[0027] More than three elongated protrusions 22 parallel to the tapered slope of the cone 21 are provided on the tapered slope of the tapered body 21 .

[0028] The protrusions 23 are symmetrically arranged with the central axis of the cone as the axis.

Abstract

A pressure adjustor mainly comprises a body, a throttling valve, a limiting platform, a tapered plate, a positioning seat, a spring and a screw. The body is made of plastic, and the outer surface of the body is provided with seal folds which are adaptive to tolerance of inner diameters of pipelines and joints manufactured by different manufacturers so as to achieve excellent airtightness. The throttling valve is provided with projections, and when pressure is overhigh, a tapered part is embedded to an outlet end, liquid or gas flows out from gaps between the outlet end and the projections, and accordingly pressure stabilization and flow control can be realized.

Description

technical field [0001] The invention relates to a pressure regulator capable of automatically adjusting water pressure and air pressure, especially the adjustment of water pressure, which belongs to the technology of automatic pressure adjustment. Background technique [0002] In the existing liquid or gas delivery systems, most of the connections between the ends and specific appliances do not have pressure regulating devices. Such as the connection between the faucet and the water pipe, the connection between the air pump and the air pressure nail gun, etc. [0003] Taking tap water as an example, the connection between the tap water pipes and the connection between the water pipe and the faucet are all realized through joints. At present, these joints mainly play the role of connection and do not have other functions. There are generally two ways to supply water to buildings at present, one is to use a booster pump to send water from bottom to top, and the other is to p...
