Description
Technical field
The utility model relates to valve technology field, particularly a kind of can the valve of pilot line pressure.
Background technique
Under normal circumstances, fluid main pipe's discharge pressure is higher, pipeline all can be costly on use material, but in our actual using process, too high pressure is not needed time a lot, and the pressure that different users needs also is different, therefore in order to economize on resources and protective conduit system, we install relief valve unit at main pipeline and time pipeline junction, it can not only convert the high pressure of main pipeline to low pressure, and the stable of outlet pressure can also be kept, outlet pressure not with main pipeline pressure and flow change and change, user-friendly.When using even without user, ducted pressure also can keep stable simultaneously, brings impact can not to valve rear line.Because pipe diameter is different, on small-bore pipeline, we directly can install reduction valve, but in order to meet usage requirement on the pipeline of large bore, reduction valve also can be connected with main valve as pilot valve and to be installed on pipeline and to use as reduction valve by we.There is the reduction valve of many types in the market, although can use, what precision, sensitivity and stability were done is not also very desirable yet.Therefore need to overcome existing technological deficiency, provide a kind of more accurate, stability more outstanding can the valve of pilot line pressure.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of valve of pilot line pressure, and no matter how inlet pressure and flow change, and maintains outlet pressure all the time constant; Meanwhile, even if outlet line is closed (not having user to use) completely, also the constant of outlet pressure can be maintained; This reduction valve both can be installed on small pipe-line and be used alone; Also main valve can be installed on for heavy-caliber pipeline as accessory.
For solving the problems of the technologies described above, the embodiment of the present application provide a kind of can the valve of pilot line pressure, comprise valve body, valve gap and spool, described valve body and valve gap are fixed by fastening piece, described valve gap upper end is provided with locking nut, adjusting screw has been threaded connection in locking nut, adjusting screw lower end apical grafting is on the top of the spring bearer plate of valve gap inner spool, the bottom of spring bearer plate is connected with spring, the other end apical grafting of spring is on the top of diaphragm pressing plate, diaphragm is arranged between diaphragm pressing plate and valve rod, diaphragm pressing plate and valve rod are fixed by butterfly spring and nut, the lower end of valve rod is threaded connection flap, metallic shim is provided with between flap and valve body, and be provided with plug screw outside valve body.
As the preferred embodiment of this programme, the outlet conduit in described valve body is rectangular in shape, and lower proper in flap, described valve rod lower end is threaded with flap through outlet.
As the preferred embodiment of this programme, described valve gap top is also provided with sheath.
As the preferred embodiment of this programme, described valve body, valve gap are by precision stainless steel casting.
As the preferred embodiment of this programme, described diaphragm adopts NBR+Nylon hangings lay.
The beneficial effects of the utility model are: structure is simple, easy for installation, and be easy to regulate, long service life, flap is workpiece vulcanized rubber, makes it have very high fatigue life, and no matter how inlet pressure and flow change, and maintain outlet pressure all the time constant; Meanwhile, even if outlet line is closed (not having user to use) completely, also the constant of outlet pressure can be maintained; This reduction valve both can be installed on small pipe-line and be used alone; Also main valve can be installed on for heavy-caliber pipeline as accessory.

Embodiment
The utility model provides a kind of valve of pilot line pressure, and no matter how inlet pressure and flow change, and maintains outlet pressure all the time constant; Meanwhile, even if outlet line is closed (not having user to use) completely, also the constant of outlet pressure can be maintained; This reduction valve both can be installed on small pipe-line and be used alone; Also main valve can be installed on for heavy-caliber pipeline as accessory.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete mode of execution, technique scheme is described in detail.
Embodiment one:
In embodiment one, as Fig. 1, present embodiments provide a kind of can the valve of pilot line pressure, comprise valve body 13, valve gap 5 and spool, described valve body 13 is fixed by fastening piece 10 with valve gap 5, detachably, easy to maintenance, described valve gap 5 upper end is provided with locking nut 3, adjusting screw 2 has been threaded connection in locking nut 3, adjusting screw 2 lower end apical grafting is on the top of the spring bearer plate 4 of valve gap 5 inner spool, the bottom of spring bearer plate 4 is connected with spring 6, the other end apical grafting of spring 6 is on the top of diaphragm pressing plate 9, diaphragm 11 is arranged between diaphragm pressing plate 9 and valve rod 12, diaphragm pressing plate 9 is fixed by butterfly spring 8 and nut 7 with valve rod 12, the lower end of valve rod 12 is threaded connection flap 14, metallic shim 15 is provided with between flap 14 and valve body 13, and be provided with plug screw 16 outside valve body 13, flap 14 separates with spool and is threaded connection, when flap is damaged or cut when be conducive to dismounting and maintenance, turn clockwise adjusting screw, after valve, setting pressure increases, be rotated counterclockwise, after valve, setting pressure reduces.Close import when outlet conduit to continue to keep 10Bar pressure, now outlet pressure can increase, and diaphragm 11 moves, and drive on flap 14 and move, flap 14 and valve seal, outlet pressure can reduce and continue to be stabilized in 3Bar, and outlet pressure reaches static equilibrium.
