Description
Technical field
This utility model belongs to valve technology field, is specifically related to a kind of have anti-blocking and current stabilization effect integrated type valve filter element.
Background technology
Valve especially regulates valve and causes because of the blocking under small guide vane stuck or damage etc. to be common problem, solves this problem most efficient method for using defecator.At present, defecator both domestic and external is typically provided separately within pipeline, and it has a disadvantage in that (1) this defecator is separate accessories, takes up room and cost；(2) impurity (such as welding slag etc.) between filter screen and regulation valve cannot be avoided to enter regulation valve；(3) this defecator is made up of steel wire, is washing away for a long time and cracky under the impact of big impurity particle, is causing filtering function to lose efficacy.
On the other hand, flow field instability is the major reason causing the problems such as pipe-line system erosion corrosion and noise.Avoid merely flow field instability difficulty very big from system design because bend pipe and cut-off, shunt, the function element such as throttling all can cause flow field unstable.For regulation valve, its noise is also had a significant impact by flowing field stability.
For this reason, it may be necessary to a kind of valve mechanism, both can avoid the use of defecator, i.e. can be integrated with filtration, flow stabilizing function on valve with steady flow condition again.
Summary of the invention
In place of the purpose of this utility model is contemplated to overcome aforementioned the deficiencies in the prior art, and provide a kind of and there is anti-blocking and current stabilization effect integrated type valve filter element, can effectively solve defecator take up room, easily lost efficacy and valve upset flow field, cause the problems such as noise.
The purpose of this utility model is achieved by the following technical measures: a kind of integrated type valve filter element, is integrated in valve internal, is made up of round buss and hemisphere end cap；Described round buss end face is connected with hemisphere end cap；Aperture is had on described hemispherical ends lid.
In technique scheme, Internal Spherical Surface and the spherical outside surface of described hemisphere end cap are concentric, inner sphere radius is not less than 1.05 times of valve latus rectum, spherical outside surface radius should mate with the aperture size on hemispherical ends lid with the difference of inner sphere radius, structurally form elongated hole, ensured the realization of current stabilization ability by elongated hole.
In technique scheme, depending on the aperture size on described hemispherical ends lid is by using the size that there is impurity particle in environment, all orifice cross sectional of quantitative commitments of aperture amass 1.1 times more than valve maximum open area of sum.
The operation principle of the integrated type valve filter element that this utility model provides is: medium, before flow valve runner, first filters through this accessory structure；Diameter is more than its contaminant filter at valve inlet by the aperture on accessory structure, it is to avoid it enters runner and results in blockage；When medium flows out valve, when this accessory structure, owing to elongated hole has dispersion runner effect, the flow field making outflow valve is more stable.
This utility model simple in construction, can be integrated in valve internal easily, saves space, and service life is long, can be prevented effectively from valve simultaneously and especially regulate valve clogging under small guide vane, and can provide steady flow condition for valve downstream.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model integrated type valve filter element.
Fig. 2 is that this utility model integrated type valve filter element uses example schematic.
Wherein: 1. round buss, 2. hemisphere end cap, 3. aperture, 4. sealing ring, 5. valve seat.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present embodiment provides a kind of integrated type valve filter element, it is made up of round buss 1 and hemisphere end cap 2；Described round buss 1 end face is connected with hemisphere end cap 2；Aperture 3 is had on described hemisphere end cap 2.
In the above-described embodiments, described round buss 1 inner surface is inner cylinder face, and outer surface is external cylindrical surface.The internal diameter of described round buss 1 should ensure that valve circulation area, and external diameter should ensure that structural strength.
In the above-described embodiments, described hemisphere end cap 2 is closed by Internal Spherical Surface and spherical outside surface and is constituted, described Internal Spherical Surface and spherical outside surface are concentric, inner sphere radius is not less than 1.05 times of valve latus rectum, spherical outside surface radius ratio inner sphere radius big 5～10mm, spherical outside surface radius should be greater than the hole diameter on hemispherical ends lid with the difference of inner sphere radius, structurally forms elongated hole, i.e. ensured the realization of current stabilization ability by elongated hole, typically take 5～10mm.
In the above-described embodiments, depending on aperture 3 size on described hemispherical ends lid is by using the size that there is impurity particle in environment, typically taking aperture 3 diameter 3-5mm, all orifice cross sectional of quantitative commitments of aperture 3 amass 1.1 times more than valve maximum open area of sum.
It is illustrated in figure 2 this utility model and uses example schematic, the present embodiment integrated type valve filter element is integrated in valve internal, valve import and export respectively set a set of, with holes hemisphere end cap 2 and are connected with round buss 1, realize sealing by sealing ring 4 and valve seat 5 between round buss 1 and other parts of valve.
Medium, before flow valve runner, first filters through this integrated type valve filter element；Diameter is more than its contaminant filter at valve inlet by the aperture on integrated type valve filter element, it is to avoid it enters runner and results in blockage.
When medium flows out valve, through this integrated type valve filter element, owing to elongated hole has dispersion runner effect, the flow field making outflow valve is more stable.
This utility model can be arranged separately in valve inlet or outlet, it is also possible to is simultaneously attached to valve inlet and outlet；Both can apply to ball valve, it is also possible to be applied to other forms such as butterfly valve.
This utility model is applied to regulate during valve etc. respond well.
This utility model includes but not limited to above example; every any equivalent carried out under spirit of the present utility model and principle or local improvement; as changed circular hole into square hole; or two these valve mechanisms are manufactured as an entirety, all will be regarded as within protection domain of the present utility model.
