Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of reduction valve be widely used in fire-fighting system or other clean water systems.
Background technique
In the too high region of tall building, city water-supply pipe network hydraulic pressure, mine and other occasions, the outlet pressure of main valve can change because of inlet pressure change, and its outlet pressure can be changed because of the change of Main valve outlet flow, the pipeline after main valve can be made to damage because pressure is excessive, or because of pressure inequality, can not ensure that in water supply system, each water spot obtains suitable service hydraulic pressure and flow.
Summary of the invention
The purpose of this utility model be to provide a kind of have improve system conditions and potential water saving effect and the reduction valve of level after hydraulic pressure higher for pipeline before valve can being reduced to valve needed for pipeline.
In order to solve the problem existing for background technique, the utility model is by the following technical solutions: a kind of reduction valve, it valve seat 10 and spool 9 of comprising valve body 8, being located at the valve gap 2 at described valve body 8 top, being positioned at described valve body 8 inside, bottom 14 is provided with bottom described valve body 8, be provided with guide pillar 12 above described bottom 14, described guide pillar 12 is fixedly connected on bottom described valve seat 10; Described valve body 8 is provided with diaphragm 1 with the joint of described valve gap 2, and be provided with diaphragm pressing plate 3 above described diaphragm 1, described spool 9 vertically runs through described diaphragm 1, diaphragm pressing plate 3, sheathed spring 4 above the periphery of described spool 9, described diaphragm pressing plate 3.
Further, described spring 4 is provided with spring bearer plate 5 with the joint of described valve gap 2.
Further, seal ring 11 is provided with between described valve seat 10, guide pillar 12.
Further, described valve body 8 is provided with O type circle 13 with the joint of bottom 14.
Further, described spool 9 is fixedly connected on described valve gap 2 by screw rod 6.
Further, described screw rod 6 is provided with pad 7 with the joint of described spool 9.
The utility model has following beneficial effect: the utility model adopts two-piece unit structural type, have compact structure, stable performance, safe and reliable, clear up the features such as easy to maintenance, be widely used in fire-fighting system or other clean water systems; The utility model adopts single seat, spring Direct driver diaphragm to reconcile pressure, and outlet pressure amplitude of variation is little, and control accuracy is high, and compressive resistance ability is strong, and within the scope of certain flow, the inlet and outlet pressure of controllable valve is certain fixed value relatively; Valve inner piece all adopts copper or stainless steel, and valve body adopts the application of epoxy resin powder, can not produce pollution to medium.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: diaphragm 1, valve gap 2, diaphragm pressing plate 3, spring 4, spring bearer plate 5, screw rod 6, pad 7, valve body 8, spool 9, valve seat 10, seal ring 11, guide pillar 12, O type circle 13, bottom 14.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of reduction valve of the utility model, as shown in Figure 1, it valve seat 10 and spool 9 of comprising valve body 8, being located at the valve gap 2 at described valve body 8 top, being positioned at described valve body 8 inside, described spool 9 is fixedly connected on described valve gap 2 by screw rod 6, and described screw rod 6 is provided with pad 7 with the joint of described spool 9.
Be provided with bottom 14 bottom described valve body 8, described valve body 8 is provided with O type circle 13 with the joint of bottom 14, and be provided with guide pillar 12 above described bottom 14, described guide pillar 12 is fixedly connected on bottom described valve seat 10, is provided with seal ring 11 between described valve seat 10, guide pillar 12.
Described valve body 8 is provided with diaphragm 1 with the joint of described valve gap 2, diaphragm pressing plate 3 is provided with above described diaphragm 1, described spool 9 vertically runs through described diaphragm 1, diaphragm pressing plate 3, sheathed spring 4 above the periphery of described spool 9, described diaphragm pressing plate 3, described spring 4 is provided with spring bearer plate 5 with the joint of described valve gap 2.
Because diaphragm 1 area in the utility model is enough large, so can open larger main valve, and under identical line size, the reduction valve of its Capacity Ratio other types is larger.In addition, the 1 pair of pressure change of the diaphragm in the utility model is more responsive, and validity can reach +/-1%.
The utility model structure is very flexible, can adopt dissimilar pilot valve, such as supporting applicable while of pressure valve, temperature valve, air loading valve, solenoid valve or several valve.
The utility model adopts two-piece unit structural type, have compact structure, stable performance, safe and reliable, clear up the features such as easy to maintenance, be widely used in fire-fighting system or other clean water systems; The utility model adopts single seat, spring Direct driver diaphragm to reconcile pressure, and outlet pressure amplitude of variation is little, and control accuracy is high, and compressive resistance ability is strong, and within the scope of certain flow, the inlet and outlet pressure of controllable valve is certain fixed value relatively; Valve inner piece all adopts copper or stainless steel, and valve body adopts the application of epoxy resin powder, can not produce pollution to medium.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
