Abstract
The utility model relates to a valve component, in particular to a throttling orifice plate unit and consists of a throttling orifice plate and a magnifying tube connected with the throttling orifice plate. The utility model is characterized in that the throttling orifice plate is a round tube. An orifice plate is arranged inside the round tube at interval, a through hole is arranged on the orifice plate and the through holes on the adjacent orifice plates are arranged in the way of counterchaning up and down. The valve component has the advantages of simple structure, convenient manufacture and long service life. Throttling and depressurization can be realized for high-pressure fluids by putting the valve component into use combined with the prior throttling valve.
Description
Technical field
The utility model relates to a kind of valve member, specifically a kind of restricting orifice group.
Background technique
Throttle valve is industrial widely used a kind of valve, and it is mainly used in the conveying and the control of fluid.Generally adopt throttle valve to carry out the adjustment and the control of pressure when the pressure of fluid being dropped to when hanging down by height.Existing throttle valve structure is generally fairly simple, and their generally suitable pressure falls under the little situation of difference and uses.For example often need hydraulic pressure is reduced to 2.5Mpa by 25Mpa in the actual production of iron and steel and power industry, general throttle valve does not then satisfy requirement.Therefore inventing a kind of novel throttle valve is highly profitable.
The model utility content
Goal of the invention of the present utility model is exactly the defective that exists at existing product, and a kind of restricting orifice group is provided, and itself and existing throttle valve are used in combination, and can realize the throttling step-down of high-pressure liquid, thereby remedy the deficiency of existing product.
The technical solution of the utility model is achieved in that it comprises that restricting orifice puts pipe with the expansion that is connected with restricting orifice, it is characterized in that: restricting orifice is a circular pipe, be interval with orifice plate in the circular pipe, have through hole on the orifice plate, the through hole on the adjacent orifice plate shifts to install up and down.
Described restricting orifice is put pipe with expansion and is connected by stud bolt; Described restricting orifice and expansion are put and are provided with O-ring seals between the pipe, are provided with 8 restriction portions in the described restricting orifice.
The utlity model has simple in structurely, easily manufactured, the advantage of long service life is used in combination itself and existing throttle valve, can realize the throttling step-down of high-pressure liquid.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the utility model A-A is to sectional view
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprise restricting orifice 1 and the expansion that is connected with restricting orifice 1 put the pipe 5, restricting orifice 1 is a circular pipe, is interval with orifice plate 6 in the circular pipe, has through hole 7 on the orifice plate 6, the through hole 7 on the adjacent orifice plate shifts to install up and down.Described restricting orifice 1 and expansion are put pipe 5 and are connected by stud bolt 2; Described restricting orifice and expansion are put and are provided with O-ring seals 4 between the pipe, are provided with 8 restriction portions 3 in the described restricting orifice.
High-pressure liquid flows into from the left end of restricting orifice 1 during work, and through the throttling of 8 restriction portions 3, the pressure of fluid is reduced to about 2.5Mpa from 25Mpa, puts pipe 5 from expansion and flows out.After throttling, can protect the facility at rear not to be hit.
