Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 3, according to the multi-functional flow control valve of the one of the specific embodiment of the invention, comprise valve body 1, air inlet adjustment pointer 2, exhaust joint 6 and enclosed switch 3, wherein, the inside of valve body 1 has chamber (space residing for enclosed switch 3), one end of valve body 1 has suction port 11, suction port 11 is by gas-entered passageway (unmarked in figure) and chamber, and the jointing of gas-entered passageway and chamber has intake valve port (see Fig. 2, the left end sealing surface of enclosed switch 3 and intake valve port are fitted and then are sealed gas-entered passageway), the bottom of valve body 1 has air outlet 13, air outlet 13 and chamber.Air inlet adjustment pointer 2 is located at the intermediate portion of gas-entered passageway, and it is used for the size of adjusting air inflow quantity.Exhaust joint 6 is located at the other end of valve body 1, and the front end of exhaust joint 6 has exhaust valve port 62 (see Fig. 1, right-hand member sealing surface and the exhaust valve port 62 of enclosed switch 3 are fitted and then seal exhaust passage), exhaust valve port 62 and chamber.Enclosed switch 3 is movably located in chamber, the front-end and back-end of enclosed switch 3 have the seal face that can fit with intake valve port and exhaust valve port 62 respectively, the sidewall of enclosed switch 3 has the elastic edge wing 31, the elastic edge wing 31 is fitted with the inwall of chamber, and in the present embodiment, enclosed switch 3 can make for rubber.
In such scheme, exhaust joint 6 is with externally threaded taper sheath, exhaust joint 6 is installed as follows: have the mounting hole communicated with chamber at the other end of valve body 1, the bore portions of mounting hole has internal thread, taper sheath to be arranged in mounting hole by screw thread and to seal with mounting hole (marking seal ring 8 in figure), exhaust is installed in the endoporus 61 of taper sheath and regulates pointer 5, exhaust regulates pointer 5 to be used for regulating the openings of sizes of exhaust valve port 62, particularly, the axial vent holes 52 that exhaust regulates the front end of pointer 5 to have rod radial air vent 51 and be communicated with rod radial air vent 51, axial vent holes 52 communicates (see Fig. 2) with the external world.
In addition, air inlet adjustment pointer 2 is threaded taper, and it is installed as follows: be protruding with installation sleeve in the upper end of valve body 1 near suction port 11, the upper end part of the endoporus of installation sleeve there is internal thread and the end portion of its endoporus to downward-extension.Now, gas-entered passageway comprises perpendicular straight part 14 and horizontal segment part 15, and the sidewall of intake valve port with the endoporus of installation sleeve is communicated with by horizontal segment part 15, and perpendicular straight part 14 is through with the front end of endoporus, and suction port 11 is through with perpendicular straight part 14.When taper is screwed into installation sleeve, the opening of perpendicular straight part 14 is aimed in the front end of taper, the intermediate portion of taper is provided with the seal ring 9 (see Fig. 1) coordinated with the hole wall of endoporus, can be adjusted the openings of sizes (regulation range: 0 to the maximum diameter flow in perpendicular straight part 14 hole) of gas-entered passageway by rotating cone body, the opening of installation sleeve is provided with jump ring 4 and is used for taper gear in the endoporus of installation sleeve.Also have, valve body 1 part at air outlet 13 place has extended outward outgoing gas connection tube 12, the outer wall of outgoing gas connection tube 12 has outside thread, outside thread is screwed with locking nut 7, valve can directly be arranged on cylinder by outgoing gas connection tube 12 by user, locking nut 7 has locking function, ensure this valve can 360 degree freely install.
When concrete this valve of use, pressurized air enters valve body 1 from suction port 11, when flowing through the pointed cone position of lower end of air inlet adjustment pointer 2, air inlet adjustment pointer 2 can regulate the air velocity flowed through herein (specifically seeing foregoing description), the aperture of air-flow on the right side of pointer (horizontal segment part 15) after regulating enters lower chambers, promote the exhaust valve port 62 that enclosed switch 3 makes it prop up exhaust joint 6 simultaneously, and then close this exhaust valve port 62.Under the influence of air pressure, the limit wing 31 of enclosed switch 3 is pressed inwardly the formation path that contracts, and is entered cylinder by the passage that the air-flow of speed governing flows through air outlet 13 through this path.When the Pressure Drop of suction port 11 end is to a certain degree, the air pressure of air outlet 13 end produces an active force to enclosed switch 3, the limit wing 31 of interior pressure is opened and blocks intake valve port simultaneously, and exhaust valve port 62 is opened, and the passage that air-flow regulates pointer 5 and exhaust joint 6 to be formed by exhaust is discharged to air.Exhaust regulates pointer 5 to be adjustable, and it is opened completely just quick exhaust function, the passage of exhaust valve port 62 is diminished just had exhaust throttle function, just made this valve become two one-way throttle valves through overregulating.
In a word, the multi-functional flow control valve that the present embodiment provides regulates pointer 5 and exhaust joint 6 by design air inlet adjustment pointer 2, exhaust, there is the function of air inlet restriction and Quick air-discharge simultaneously, also there is the function of relief opening throttling, that is, as long as with a multi-functional flow control valve, both can work as an one-way throttle valve and add a rapid escape valve use, also can work as two one-way throttle valves to use, convenient and practical, cost-saving.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
