Abstract

The utility model relates to a high voltage material angle valve with spoilers. The high voltage material angle valve comprises an angle valve body. The angle valve body takes the shape of the right angle. A valve seat is arranged at the outlet of the angle valve body, and a valve core is installed in the valve seat. A valve rod is arranged in the angle valve body; the valve rod and the valve spool form an integral structure; and the top end of the valve rod passes through the angle valve body. The high voltage material angle valve is characterized in that the spoilers are arranged on the internal cavity wall of the angle valve body. The spoilers are respectively arranged on the internal cavity wall on the surface opposite to the inlet of the angle valve body, on the internal cavity wall on the left side surface and on the internal cavity wall on the right side surface of the angle valve body. The valve seat is sealed with the outlet of the angle valve body by a sealing gasket. The high voltage material angle valve has the advantages of simple structure and good safety and reliability and greatly reduces the production cost.

Description

High-pressure material angle valve with turbulence blades

Technical field

The utility model relates to a kind of high-pressure material angle valve, specifically a kind of high-pressure material angle valve with turbulence blades.

Background technique

Along with improving constantly of domestic industry automatization level, modulating valve is as the most frequently used, most important final controlling element in the process control, its overall development speed is very quick, but the material angle valve development speed at harsh operating modes such as high temperature, High Pressure Difference is but slow relatively, most of high-pressure material angle valve trim is washing away and serious wear because of the high speed MEDIA FLOW all, significantly reduce the working life of product, brought the tremendous economic loss.Step-down, the noise-reduction method that high-pressure material angle valve is commonly used generally adopts and installs orifice sleeve, labyrinth group etc. additional at present, though the portioned product using effect is comparatively desirable, cost of production is too high.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of stable, safe and reliable high-pressure material angle valve with turbulence blades is provided.

According to the technological scheme that the utility model provides, a kind of high-pressure material angle valve with turbulence blades comprises the angle valve valve body, and described angle valve valve body is a rectangular shape, is provided with valve seat in the outlet port of angle valve body, and spool is installed in valve seat; In the angle valve valve body valve rod is housed, described valve rod and spool are integral structure; Feature is: on the internal chamber wall of described angle valve valve body turbulence blades is set.

Described turbulence blades is separately positioned on the internal chamber wall of angle valve valve body import right opposite, on the left surface internal chamber wall and on the right flank internal chamber wall.

Seal with gasket seal between described valve seat and the angle valve valve body.

Compared with the prior art the utility model has the following advantages:

1, adopts body cavity flow-disturbing technology, can be good at the flow velocity of control media, reduce the erosion effect of MEDIA FLOW, prolong the working life nearly 30% of product trim;

2, avoid the vortex phenomenon of high speed MEDIA FLOW initiation, improved the dynamic stability of valve, degree of regulation improves about 20%;

3, product structure is simple, and is safe and reliable, significantly reduced cost of production.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A view of Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As Fig. 1～shown in Figure 2: the high-pressure material angle valve with turbulence blades comprises turbulence blades 1, angle valve valve body 2, valve rod 3, spool 4, valve seat 5, gasket seal 6 etc.

The utility model comprises angle valve valve body 2, and described angle valve valve body 2 is a rectangular shape, is provided with valve seat 5 in the outlet port of angle valve valve body 2; Valve rod 3 is housed in angle valve valve body 2, and valve rod 3 is an integral structure with spool 4, and the top of valve rod 3 passes angle valve valve body 2, and described spool 4 is installed in the valve seat 5, seals with gasket seal 6 between valve seat 5 and the angle valve valve body 2; Be provided with turbulence blades 1 in the angle valve valve body 2, described turbulence blades 1 is separately positioned on the angle valve valve body 2 import right opposite internal chamber walls, on the left surface internal chamber wall and on the right flank internal chamber wall.

Working principle of the present utility model: the turbulence blades 1 in the body cavity described in the utility model amounts to three, directly is made in angle valve valve body 2 inner chambers right opposite that the location arrangements of turbulence blades 1 is washed away in MEDIA FLOW, left surface and right flank during the die sinking tool.When high speed MEDIA FLOW entering angle valve body 2 inner chambers are flowed through turbulence blades 1, turbulence blades 1 can be divided into the high speed MEDIA FLOW multi beam MEDIA FLOW, the damping function of turbulence blades 1 makes the flow velocity of medium reduce greatly, and medium obviously reduces the erosion effect meeting of trim like this; Can avoid simultaneously the eddy current that causes because of the high speed MEDIA FLOW, eddy current can produce great uneven moment of torsion to valve rod, mangetic core assembly, can cause the generation of situations such as valve rod distortion, fracture, trim vibration like this, have a strong impact on the degree of regulation and the safety in utilization of product.
