Abstract

The utility model discloses a single valve manifold valve. The single valve manifold valve has the technical proposal that a revolving sphere is installed inside a valve body, and a channel is arranged in the revolving sphere. The channel is communicated with an external connection pipeline by an oblique hole. The revolving sphere is driven by an operating valve rod to rotate, and a plurality of fluid pipelines can be synchronously switched.

Description

Single valve manifold valve

The utility model belongs to the multiple-way valve technical field, is used to control the path of a plurality of fluids.

At present, in fluid delivery system, mostly adopt several stop valves or threeway, four-way, multiple-way valve to realize switching to several pipelines, its shortcoming one is that valve quantity is big in the system, the 2nd, can not accomplish that several valves is synchronous fully during operation, be prone to error.At above-mentioned shortcoming, someone has designed a kind of multiple way and multiple switching valve, this valve mainly is a valve plug to be installed constitute in valve body, is provided with in the valve plug to have two not connected passages at least, and the rotation valve plug can make between two imports and two export pipelines synchronously switch at least at least.The shortcoming of this valve is: in order realizing and being connected of external pipeline, must to process several auxiliary holes on valve body, all to want the installing technological hole plug in each auxiliary hole, and to install sealing gasket additional, so not only make complex structure, processing is inconvenient, and easily causes the seepage of fluid in the using process.

The purpose of this utility model is that design is a kind of simple in structure, easy to process, but can switch the single valve manifold valve of many pipelines and eliminate fluid seepage simultaneously.

The utility model comprises the valve body that is made of upper valve body and following valve body, the single-revolution spheroid is installed in the valve body, be provided with in this revolution spheroid and have two not connected passages at least, on the revolution spheroid valve rod that stretches out valve body is installed, on the valve body of revolution around the spheroid, be provided with valve seat, be provided with in it when turn round spheroid when rotateing in place can with the pipeline of channel alignment; Connecting-tube nozzle is installed on the valve body, it is characterized in that between connecting-tube nozzle and pipeline, having the inclined hole that the two is communicated with.

Have at least in the passage in the utility model revolution spheroid two not connected, can switch simultaneously several pipelines by rotating this revolution spheroid, connecting-tube nozzle is communicated with by the inclined hole between them with pipeline on the valve seat, cancelled auxiliary hole, also just cancelled the auxiliary hole plug, both made the simple in structure of product, be convenient to processing, cancelled again because of being provided with the seepage that auxiliary hole brings.

Be example with the single valve manifold valve that replaces three valve groups below, preferred embodiment of the utility model is described.

Fig. 1 is embodiment's a structural representation;

Fig. 2 is the plan view of Fig. 1;

Fig. 3 is the plan view of revolution spheroid;

Fig. 4 is the A-A sectional view of Fig. 3;

Fig. 5 is the B-B sectional view of Fig. 3;

Fig. 6 is the C-C sectional view of Fig. 3.

Embodiment shown in the accompanying drawing has a valve body that is made of upper valve body (12) and following valve body (13), and single-revolution spheroid (8) is installed in the valve body, is locating to be provided with seal ring (11) near revolution spheroid (8) between the valve body up and down.In revolution spheroid (8) valve rod (1) that stretches out valve body is installed, rotates this valve rod (1) and can make revolution spheroid (8) press assigned direction and angle rotation with the change station.Valve body is equipped with plug (3) and is provided with seal ring (4) on the position that valve rod (1) is installed, and is filled with sealing material (2) in the plug (3).Be provided with in revolution spheroid (8) and have two not connected passages (10) at least, by Fig. 3-Fig. 6 as can be seen, the angle between three sections of revolution spheroid (8) is 60 °, is provided with passage (10) on its different section.Be provided with four valve seats (7) on revolution spheroid (8) valve body on every side, be provided with pipeline (9) in it, when turning round spheroid (8) when rotateing in place, this pipeline (9) can be aimed at passage (10) and be communicated with, and valve seat is embedded with sealing material in (7).4 connecting-tube nozzles (5) are installed on the valve body, between its mouthful end and pipeline (9), have and make the two inclined hole that is communicated with (6).Like this, external pipe can directly be communicated with by this inclined hole (6) with passage (10), thereby does not need to establish auxiliary hole and installing technological hole plug again.

At present, people are combined together differential pressure transmitter, three valve groups and throttling arrangement usually, are used for measuring flow, pressure of fluid etc.Three valve groups wherein are equivalent to three stop valves.After replacing three valve groups with the utility model, can make operation synchronously, easy to operate, error is little.Turning round the residing section of spheroid (8) among Fig. 1 also is the halted state that the section shown in Fig. 4 is equivalent to three valve groups.Press among the figure direction of arrow when valve rod (1) and rotate 60 °, when making revolution spheroid (8) be in the residing section of Fig. 5, the zero-bit that promptly is equivalent to three valve groups is adjusted state; When being rotated further revolution spheroid (8), promptly be equivalent to the running state of three valve groups to section shown in Figure 6.

The single valve manifold valve can be designed to various ways according to the specific requirement of a plurality of fluids of need switching, and a plurality of fluids that is switched needs several connected states, it can be designed to several stations.

Claims

1, a kind of single valve manifold valve, comprise the valve body that constitutes by upper valve body (12) and following valve body (13), single-revolution spheroid (8) is installed in the valve body, be provided with in this revolution spheroid (8) and have two not connected passages (10) at least, on the revolution spheroid (8) valve rod (1) that stretches out valve body is installed, on revolution spheroid (8) valve body on every side, be provided with valve seat (7), be provided with the pipeline (9) that to aim at passage (10) when rotateing in place when revolution spheroid (8) in it, connecting-tube nozzle (5) is installed on the valve body, it is characterized in that between connecting-tube nozzle (5) and pipeline (9), having and make the two inclined hole that is communicated with (6).

2, by the described single valve manifold valve of claim 1, it is characterized in that described inclined hole (6) has 4, the pipeline (9) in four valve seats (7) is communicated with respectively with 4 connecting-tube nozzles (5).
