Abstract
The invention discloses a voltage regulation valve, which comprises a valve body, wherein a liquid inlet and a liquid outlet are arranged in the valve body, and a spool is arranged in the valve body. The voltage regulation valve has the innovative points that the liquid inlet and the liquid outlet in the valve body are vertically communicated with each other, and the top end of the valve body is fixedly connected with an upper cover; a baffle is arranged at the liquid inlet of the valve body, and a tapered hole is arranged in the baffle; the inner surface of the upper cover is propped against one end of a spring, and a spring seat is also arranged in the valve body; the other end of the spring is propped against the spring seat, and the spring seat is fixedly connected with the spool through a connecting rod; and the spool is a frustoconical body and slides in the tapered hole, and the diameter D of the lower bottom surface of the frustoconical body is greater than the small inner diameter d1 of the tapered hole and is smaller than the large inner diameter d of the tapered hole. The voltage regulation valve provided by the invention has the characteristics of simple structure and low production cost.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of pressure maintaining valve for the stable flow.
Background technique
At present, in the transportation process of liquid, all adopt pipeline to connect and carry.This just requires well to control the pressure in the conveyance conduit, when manifold pressure is excessive, again always to transportation pressurization in the pipeline, can impact pipeline, form pipe explosion accident, thereby affect delivery safety, this just needs a kind of valve that can control liquid pressure in the pipeline to control the pressure of pipeline.Existing pressure maintaining valve adopts electronic control flow and flow velocity mostly, its complex structure, and control program is loaded down with trivial details, and manufacture cost is large.
Summary of the invention
The object of the present invention is to provide a kind of pressure maintaining valve of simple in structure, low cost of manufacture.
In order to achieve the above object, technological scheme of the present invention is: a kind of pressure maintaining valve has valve body, have liquid entering hole and liquid outlet on the valve body, spool is housed in the valve body, and its innovative point is: the liquid entering hole on the described valve body communicates with liquid outlet is vertical, and the top of described valve body is fixedly connected with loam cake; The liquid entering hole place of valve body has plate washer, has taper hole on the plate washer, and an end of the inner face of loam cake and spring offsets, and also is provided with spring seat in the described valve body, and the other end and the spring seat of described spring offset; Described spring seat is fixedly connected with spool by connecting rod, and described spool is cone table, and spool is slippage in taper hole, and the diameter D of cone table bottom surface is greater than the little inner diameter d of taper hole
1And the large diameter d less than taper hole.
The place, lower end surface that is positioned at spring seat of described valve body is provided with stop.
The periphery of described loam cake is fixedly connected with valve body by bolt, and the height at loam cake middle part is higher than limit section.
Has seal ring between described valve body and the spring seat.
After adopting said structure, because the liquid entering hole on the described valve body communicates with liquid outlet is vertical, the top of described valve body is fixedly connected with loam cake; The liquid entering hole place of valve body has plate washer, has taper hole on the plate washer, and an end of the inner face of loam cake and spring offsets, and also is provided with spring seat in the described valve body, and the other end and the spring seat of described spring offset; Described spring seat is fixedly connected with spool by connecting rod, and described spool is cone table, and spool is slippage in taper hole, and the diameter D of cone table bottom surface is greater than the little inner diameter d of taper hole
1And the large diameter d less than taper hole.By the slippage in taper hole of spring band movable valve plug, the elastic force that spring is intrinsic so that spool can guarantee in taper hole, and leave the gap between spool and the taper hole, liquid is from the liquid entering hole feed liquor, enter valve body by the gap between spool and the taper hole after, flow out from liquid outlet.When current broken hair was given birth to the fault obstruction, the pressure in the valve body was excessive, and liquid pressure holds out against spring, and the spring band movable valve plug upwards holds out against, so that spool and taper hole are fitted fully, liquid just can not flow to valve body more like this, has played the effect of damming.The present invention has well controlled the pressure of liquid in the valve body, and it is simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of working state of the present invention;
Fig. 2 is the structural representation that is in current floe condition of the present invention.
Embodiment
The present invention is further detailed explanation below in conjunction with embodiment that accompanying drawing provides.
As shown in Figure 1, 2, a kind of pressure maintaining valve of the present invention has valve body 1, have liquid entering hole 2 and liquid outlet 3 on the valve body 1, spool 4 is housed in the valve body 1, it is characterized in that: the liquid entering hole 2 on the described valve body 1 and liquid outlet 3 vertical communicating, the top of described valve body 1 is fixedly connected with loam cake 5; Liquid entering hole 2 places of valve body 1 have plate washer 6, have taper hole 6-1 on the plate washer 6, and an end of the inner face of loam cake 5 and spring 7 offsets, and also are provided with spring seat 8 in the described valve body 1, and the other end of described spring 7 and spring seat 8 offset; Described spring seat 8 is fixedly connected with spool 4 by connecting rod 9, and described spool 4 is cone table, spool 4 slippage in taper hole 6-1, and the diameter D of cone table bottom surface is greater than the little inner diameter d of taper hole 6-1
1And the large diameter d less than taper hole 6-1.The present invention only need directly cooperate with taper hole 6-1 by spool 4, drive by spring 7, so that spool 4 can move up and down along with the pressure of liquid entering hole 2 interior liquids, when valve body 1 interior liquid pressure is excessive, liquid pressure holds out against spring 7, so that spool 4 fits with taper hole 6-1, so just so that cut off by spool 4 between liquid entering hole 3 and the liquid outlet 2, played the effect of the interior liquid pressure of stable valve body.Of the present invention simple in structure, fabricating cost is low, and is easy to use.
As shown in Figure 1, 2, the place, lower end surface that is positioned at spring seat 8 of described valve body 1 is provided with stop 12.Can prevent like this spring seat 8 when moving down, be slipped to the intersection gap between liquid entering hole 2 and the liquid outlet 3 and cause spring seat 8 not reset.
As shown in Figure 1, 2, the periphery of described loam cake 5 is fixedly connected with valve body 1 by bolt 10, and the height at loam cake 5 middle parts is higher than limit section.Can conveniently install and remove loam cake 5, can adjust and change spring 7 behind the loam cake 5 of dismantling, and the middle part of loam cake 5 highly be higher than limit section, have mounting or dismounting conveniently, the effect of being convenient to install.
As shown in Figure 1, 2, has seal ring 11 between described valve body 1 and the spring seat 8.Prevent that the liquid in the valve body 1 from flowing into the top of spring seat 8, causes the phenomenon of leakage.Accordingly, above valve body 1 upper spring seat 8 or on loam cake 5, can have air hole, the space that prevents spring seat 8 tops form be difficult to after the vacuum mobile, stuck.
