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
The present invention relates to a kind of adjustment that automatically can adjust the pressure regulator, particularly hydraulic pressure of hydraulic pressure, air pressure, belong to pressure automatic adjustment technology.
Background technique
In the transporting system of existing liquid or gas, mostly there is no pressure controlled device in the connection of end and concrete apparatus.As tap and the connection of water pipe, the connection etc. of air pump and air pressure nail gun.
For tap water, the connection between water supply pipe, the connection between water pipe and tap, is all realized by joint.These joints mainly play the effect of connection at present, do not possess other functions.Current building supplies water, and generally has two kinds of modes, a kind of be use suction booster from bottom to top send water mode, one settles water tank at roof, utilizes the mode that water-head is carried from top to bottom.Be no matter anyly send water mode, different floor hydraulic pressure also can be different, thus cause different floor water-outlet quantity different.
Be disclose a kind of water-saving type pipe joint and unlatching or method for closing in the patent document of 200910098530.3 at application number, advantage is the dual functions with pipe joint and stop valve, and deficiency is the ability not possessing pressure adjusting.
Be disclose a kind of water pipe adapter in the patent document of 201020694127.5 in the patent No., can along with the change of hydraulic pressure, water yield adjusting, when hydraulic pressure is excessive, throttle valve clogs water outlet, and water can only flow out from the spilled water hole throttle valve, play the effect of pressure control current stabilization, reach the object of water saving.But in the application of reality, when the installation of water system completes, the water pipe adapter of part water outlet is embedded in wall, reequip and just difficult for very much.
Therefore, need to find a kind of installation more simple, do not need voltage stabilizing throttle device supply system being done to large transformation.
Summary of the invention
The object of this invention is to provide a kind of installation simply, do not need voltage stabilizing throttle device existing system being done to large transformation.
Technological scheme of the present invention is: pressure regulator forms primarily of body 1, throttle valve 2, limiting platform 3, taper platform 4, positioning seat 5, spring 6, screw 7, described throttle valve 2 comprises again taper 21, projection 22, valve rod 23, described positioning seat 5 is placed on limiting platform 3, described valve rod 23 passes the center hole of positioning seat 5 from outlet end to entrance point, screw 7, through spring 6, is tightened on the inner bolt hole of valve rod 23.Described body 1 adopts plastic production, and outer surface is provided with sealing pleat 11.
The tapered slope of described taper 21 is provided with more than three elongated projection 22 parallel with the tapered slope of taper 21.
Described projection 23, symmetrically arranges for axle center with the axis of taper.
Described valve rod 23 is provided with the positioning key 231 matched with the locating slot 51 on positioning seat 5 center bore inner wall.
Described limiting platform 3 is positioned at body 1 inwall, is the hollow cylindrical coaxial with body 1; The entrance point of described taper platform 4 connects with the outlet end of limiting platform 3.
The entrance point aperture of described taper platform 4 is greater than the aperture of outlet end.
The maximum diameter of described taper 21 is less than the maximum diameter of hole of taper platform 4, and the tapered slope of described taper 21 is parallel with the tapered slope of taper platform 4.
The invention has the beneficial effects as follows:
1, can in mounted pipe network system, do not need to do and significantly reequip, change, only need in pipe coupling, install pressure regulator of the present invention additional, just can play the effect of voltage stabilizing flow control.
2, outside body, be provided with sealing pleat, can self adaption different manufacturers produce pipeline, joint id tolerance, play the effect of well sealing.
3, on throttle valve, be provided with projection, when pressure is excessive, taper embeds outlet, and liquid or gas flow out from the gap between outlet and projection, effectively prevent the generation of shutoff phenomenon.

Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, pressure regulator forms primarily of body 1, throttle valve 2, limiting platform 3, taper platform 4, positioning seat 5, spring 6, screw 7, described throttle valve 2 comprises again taper 21, projection 22, valve rod 23, described positioning seat 5 is placed on limiting platform 3, described valve rod 23 passes the center hole of positioning seat 5 from outlet end to entrance point, screw 7, through spring 6, is tightened on the inner bolt hole of valve rod 23.Described body 1 adopts plastic production, and outer surface is provided with sealing pleat 11.
The tapered slope of described taper 21 is provided with more than three elongated projection 22 parallel with the tapered slope of taper 21.
Described projection 23, symmetrically arranges for axle center with the axis of taper.
Described valve rod 23 is provided with the positioning key 231 matched with the locating slot 51 on positioning seat 5 center bore inner wall.When liquid or gas flow through taper time, under the effect of the pressure, likely rotate and cause screw to get loose, valve rod 23 arranges positioning key 231 and interacts with the locating slot 51 on positioning seat, the generation rotated can be prevented.
Described limiting platform 3 is positioned at body 1 inwall, is the hollow cylindrical coaxial with body 1; The entrance point of described taper platform 4 connects with the outlet end of limiting platform 3.
The entrance point aperture of described taper platform 4 is greater than the aperture of outlet end.
The maximum diameter of described taper 21 is less than the maximum diameter of hole of taper platform 4, and the tapered slope of described taper 21 is parallel with the tapered slope of taper platform 4.
Before using, pressure regulator is filled in the hole of pipeline, joint by flow direction.
As shown in Figure 1, for current, when current flow through outlet end 13 from the entrance point 12 of pressure regulator, the pressure of water makes throttle valve 2 move to the direction of taper platform 4.When the pressure of current is less, the underpressure that current produce on taper 21 is to overcome the pressure of spring, and the position of throttle valve 2 can not change, and flows through to smooth in water flow positioning seat 5, taper 21, flows out from outlet end 13; When the pressure increase of current, the pressure that current produce on taper 21 overcomes the pressure of spring, taper 21 is moved to the direction of outlet end 13, cause the distance of taper 21 and outlet end 13 along with the increase of pressure more and more less, until taper 21 embeds taper platform 4 completely, projection 23 makes to form gap between the outer rim of taper 21 and taper platform 4, as shown in Figure 2, at this moment, current can only be flowed out by the gap between taper 21 and taper platform 4.
Taper by above-mentioned motion, thus reaches the effect of voltage stabilizing flow control.
Above-described embodiment is only used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
