Description
Technical field
The utility model relates to pressure regulator field, particularly relates to a kind of pressure regulator containing single spring structure.
Background technique
At present, the reduction valve generally used comprises two spring structures usually, the spring of bottom and spring above with plunger center dynamics for balancing, upper end is moved on to by barrier film cut-out pressure, when entrance adds high pressure, plunger moves on to upper end and outlet passage mouth can be diminished, and therefore prevents the rising of outlet pressure; When contrary entrance adds low pressure, plunger moves down and outlet passage mouth can be become large, therefore prevent the decline of outlet pressure; Although the pressure according to above operating principle entrance changes to some extent, but outlet maintains certain pressure.But this reduction valve needs 2 springs, complex structure, must need to use high voltage bearing barrier film, the expense of barrier film is higher, therefore causes holistic cost higher, and need to use screw fixed installation assembly wherein, that has assembled manually must adjust screw in order to Adjustment Performance; Therefore cannot accomplish the uniformity of product and not reach quality requirement, also wanting assembling nut, reduce manufacturing efficiency, causing operating cost too high.
How to found a kind of structure simple, easy for installation, with low cost, the pressure regulator of the single spring structure that manufacturing efficiency is high, tool is of great significance.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of pressure regulator containing single spring structure, make its structure simple, easy for installation, can only use a spring structure to realize pressure adjusting function, thus overcome existing reduction valve or other pressure regulator complex structures, need by two spring controlled deficiencies.
For solving the problems of the technologies described above, the utility model provides a kind of pressure regulator containing single spring structure, comprise entrance, outlet, valve body, axle, slide block, spring, sealing gasket, described axle is arranged on the upper end of valve body, the lower end of axle is provided with slide block, spring is provided with between axle and slide block, described slide block inside is provided with center hole, slide block top is provided with groove port and diverter module, diverter module is provided with sealing gasket, also be provided with the first seal ring between described axle and slide block, between described slide block and valve body, be provided with the second seal ring.
Further, the upper end of described axle is provided with the 3rd seal ring, and the bottom of described valve body is provided with the 4th seal ring, and the top of the 3rd described seal ring and the lower end of the 4th seal ring are equipped with pad.
After adopting such design, the utility model at least has the following advantages:
The utility model utilizes 1 spring adjustment pressure to reach desired object, and structure is simple, easy to assembly, the shortcoming of loaded down with trivial details, the manual tune of the assembling of pressure regulation device before can overcoming, convenient disassembly, long service life, failure rate is low, and convenient for maintaining, change, user cost is low.
Each parts are connected and have picked out seal ring or sealing gasket, have efficient sealing effect.
Can use the manufacture of common reduction valve material, manufactured materials is conveniently easy to get.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the internal structure schematic diagram of a kind of pressure regulator containing single spring structure of the utility model.
Fig. 2 is package assembly schematic diagram of the present utility model.
Fig. 3 is the structural representation of slide block of the present utility model.
Wherein, 1 is entrance, and 2 is outlet, and 3 is axle, and 4 is pad, and 5 is the 4th seal ring, and 6 is valve body, and 7 is the second seal ring, and 8 is slide block, and 9 is the first seal ring, and 10 is sealing gasket, and 11 is spring, and 12 is the 3rd seal ring.
Embodiment
With reference to shown in Fig. 1-3, the utility model provides a kind of pressure regulator containing single spring structure, comprise entrance 1, outlet 2, valve body 6, axle 3, slide block 8, spring 11, sealing gasket 10, described axle 3 is arranged on the upper end of valve body 6, the lower end of axle 3 is provided with slide block 8, spring 11 is provided with between axle 3 and slide block 8, described slide block 8 inside is provided with center hole 82, slide block 8 top is provided with groove port and diverter module 81, diverter module 81 is provided with sealing gasket 10, the first seal ring 9 is also provided with between described axle 3 and slide block 8, the second seal ring 7 is provided with between described slide block 8 and valve body 6.
Preferably, the upper end of described axle 3 is provided with the 3rd seal ring 12, and the bottom of described valve body 6 is provided with the 4th seal ring 5, and the top of the 3rd described seal ring 12 and the lower end of the 4th seal ring 5 are equipped with pad 4.
Leave certain distance between diverter module 81 and the center hole of slide block, gas or liquid flow in slide block from center hole 82 after diverter module 81 is shunted.
During use, gas or liquid are from entering, 1 passage flowed into through slide block 8 flows to outlet port, when entrance 1 place's pressure increase, export 2 place's pressure and also can increase, this can make to receive bottom slide block 8 to upward pressure, slide block moves to entrance 1 direction, gas or fluid flow paths mouth are diminished, and flow diminishes, thus reduces the pressure at outlet 2 place; Contrary, when the pressure at entrance 1 place reduces, the pressure exporting 2 places also can reduce, the pressure be subject to bottom slide block 8 reduces, and slide block 8 moves down under the active force of spring 11, makes gas or fluid flow paths mouth become large, flow increases thereupon, thus increase the pressure at outlet 2 place, by the position of adjusting slider 8 repeatedly, maintain outlet pressure balance.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
