Abstract
A valve(1) for a pressure container(4) serving for distributing a liquid, e.g. beer, under pressure of a gas, e.g. CO2. The valve has a valve seat(8) defining a valve axis(27), an elastomeric valve ring(2) placed coaxially to the valve seat with a preferably coaxially embedded reinforcing ring(17) of e.g. metal, a gas passage(7) which is formed between the valve-ring seat(8) and the valve ring(2) when opening the valve(1), and a liquid passage(10) which is formed at the same time through the central opening(13) of the valve ring. The rim(21) of the reinforcing ring(17) is divided into three sectors(24) of a circle with a larger diameter than the opening(25) of the valve seat(8). The circle sectors(24) are again divided by three curved recesses(26). When the pressure in the container(4) exceeds a preselected permissible overpressure, the elastomeric material in the recesses is deformed to such an extent that openings(29) are made for relieving the overpressure. Thus, the valve according to the invention can function as a very efficient relief valve.
Description
Technical field
The present invention relates to a kind of safety valve that is used for the pressure container of dispensing liquid under gaseous tension, this valve contains the fluid passage of a valve seat that limits valve axis, and this valve seat elastomeric material valve collar coaxial setting and that have ring stiffener, a gas passage that forms and a centre hole that passes through valve collar of formation when valve is opened between valve seat and valve collar when valve is opened.
Background technology
Movable pressure container is used for the beverage (as: beer) that several parts are sold in restaurant for example, and in the time will use said vesse, just connector of installation on its valve, this connector make and be contained in pressure gas and (be generally CO
2) pressure bottle or jar be connected so that extract beverage with cooperage spigot.In connector, there is one can move by handle and open the axle pipe of valve.
In order in transportation and storage process, to make beverage freshness remaining, must keep gaseous tension, so its valve must always remain on sealing state fully closely.So common valve collar all uses elastomeric material (for example: rubber) make, abut against respectively on the above-mentioned gas passage and fluid passage thereby elastic deformation can take place by the loading of at least one compression spring the valve collar of this elastomeric material.
The necessary condition of security seal is, valve collar will be subjected to its elastomeric material and just be difficult to the bigger power of bearing when not curved.Therefore, gas passage and/or fluid passage are sewed easily, and can force valve collar to leave its position in valve.
Therefore, the tabular ring stiffener made from a kind of strong and hard material (as corrosion-resistant steel) increases above-mentioned common valve collar rigidity.During fabrication adhesives is coated on the ring stiffener, it and elastomeric material are bonded together becomes a single piece then.
Without any danger, its operation pressure has only number crust to movable Pressure vessels to surrounding environment, and the size of container is made have big safety factor with respect to above-mentioned pressure.But, if container is subjected to strong heating (for example building situation about burning), the pressure in the container will raise so that container is blasted and impact and grievous injury near the crowd.
When above-mentioned pressure container was used for the splendid attire beverage, they were difficult to load onto the special safety valve too high pressure of releasing.In other words, in other situation, because the following fact, promptly safety valve is a kind of quite complicated mechanism efficiently, it has many parts and many out of reach bent angles is arranged, this just makes and is difficult to even may not clear up safety valve satisfactorily when the cleaning empty receptacle, is that this safety valve may become the vegetative source that for example can damage or stain the beverage of storing in the container so always there is a kind of danger.
Common valve arrangement means and can effectively and safely clear up this valve under the situation of not pulling down valve in the cleaning empty receptacle.But this structure means simultaneously that also valve just cut out tightlyer when pressure raise.Therefore, the common valve of this class itself can not guarantee that container does not explode when superpressure.
Summary of the invention
The safety valve that the purpose of this invention is to provide a kind of pressure container, this valve have whole advantages of common valve, cleaning well equally easily, and can guarantee that structurally container do not blast under very high superpressure.
For realizing above-mentioned purpose of the present invention, the invention provides a kind of safety valve that is used for the pressure container of dispensing liquid under the pressure of gas, this valve contains: the valve seat of a regulation valve axis; One with above-mentioned valve collar seat elastomeric material valve collar coaxial arrangement and that have ring stiffener; , a gas passage that when valve is opened, between valve seat and valve collar, forms; Fluid passage with a centre hole that passes through valve collar that when opening above-mentioned valve, forms, it is characterized in that, the neighboring of ring stiffener forms a curved surface, and this curved surface contains at least one first farther apart from the valve axis ratio apart from the inner edge of valve collar seat and the nearer second portion of at least one distance.
When the superpressure in the container reached predetermined value, the elastomeric material of valve collar partly was forced to begin by valve seat till first peripheral part of ring stiffener is close to valve seat, and prevent safety link be pressed into can infringement around in the space of part.Under sufficiently high superpressure, ring stiffener deforms, and the elastomeric material of valve collar bends at its second periphery, thereby forms the opening of the superpressure in the release container between valve collar and valve-ring seat.Therefore, safety valve of the present invention plays the effect of highly effective safety valve.
Do not blast in order fully to guarantee container because of too high superpressure, distance between valve axis and the peripheral curve first is made be 0.9～1.2 times of distance between (preferably 1.0～1.1 times to) valve axis and valve seat inside circumference, be made the distance of valve axis and above-mentioned second portion make 0.75～0.95 times of distance between (preferably 0.8～0.9 times to) valve axis and valve seat inside circumference simultaneously.
One simple especially and in the advantageous embodiments, the first of the curved surface that is formed by the neighboring of ring stiffener is positioned on the circumference, and its second portion is made the curved recessed portion on this circle neighboring.
In fact, if make the neighboring of ring stiffener make by a plurality of the composition by the spaced circumference of many recesses be favourable.
For can be by the opening of the above-mentioned recess too high superpressure in the container of releasing, each above-mentioned recess must be crossed over enough big area, simultaneously, the material thickness of ring stiffener is too thick scarcely, proved already, when the maximum width of each recess doubled the thickness of ring stiffener at least, above-mentioned valve collar just can play the effect of safety valve effectively.
If above-mentioned recess also has sharp keen edge, effect can be better, because above-mentioned edge can completely or partially be cut in the elastomeric material.
Above-mentioned ring stiffener is preferably made a plate with bottom and annular lip.Because ring stiffener has the two-fold curved-surface structure, so it has the big section modulus of bearing axial load, therefore, under the superpressure effect in container, ring stiffener forces the hole of elastomeric material by valve seat in advance.
When valve collar has a protruding circle in the face of valve seat, the annular lip of ring stiffener is preferably from being fit into one section short range less than 2mm in the above-mentioned protruding circle with above-mentioned protruding circle in the face of the opposite side of a side of valve seat, so as to make in each recess and each recess on the thickness of elastomeric material enough be thinned to and have little section modulus, thereby make material that enough distortion can take place under the effect of predetermined excess.

The specific embodiment
Movable container is used at CO
2Pressure under beverage (as: beer, cola, soft drink and grape wine etc.).But this container also can be used for transporting many other liquid, and described gas is except CO
2Also can be other gases in addition.Described container is also not necessarily movable, and it also can be fixed.
Safety valve 1 of the present invention can be a structure shown in the drawings, still, also can have other many structures.Therefore, embodiment shown in Figure 1 only is used in the following description as example of the present invention, and, because structure itself is known, so the following brief description of only doing.
Safety valve 1 mainly is made up of a valve body 5 and a stalk 6 (its part only is shown) that is installed in movably in the valve body that is screwed in the attaching parts 3 on the pressure container 4 by screw thread.Fig. 1 left side illustrates valve 1 and is in opening, and the right then illustrates valve 1 and is in closed condition.In addition, settled a valve collar 2 that is used to open and close the elastomeric material of valve in the valve seat 8 in valve 1 coaxially, Fig. 2 illustrates the enlarged drawing of this valve collar 2.
When valve 1 is opened (shown in Fig. 1 left side), form a gas passage 7 between the valve seat 8 in valve body 5 and the contact surface 9 of valve collar 2.Form a fluid passage 10 in addition between valve-ring seat 12 in valve plug 11 and valve collar centre hole 13.If when wanting shutoff valve (state shown in Fig. 1 the right),, till the contact surface 9 of valve collar is close to valve seat 8, thereby gas passage 7 is closed just stalk 6 is moved with valve collar 2 by first compression spring 14.Meanwhile, move valve plug 11, make it to be close to valve-ring seat 12, thereby also closed fluid passage 10 by second compression spring 15.
In the time that container 4 will be used, a connector (not shown) that has movable pivoting axis pipe 16 (its underpart only is shown among Fig. 1) is installed removably on its valve 1 just.The bottom of this axle pipe 16 places on valve plug 11 and the valve collar 2, and valve plug 11 and valve collar 2 can move apart their base 8,12, and therefore, the handle (not shown) on being operatively connected head is when moving down axle pipe 16 among the figure, and valve 1 is just opened.
The connector that is connected with pressure bottle that fills pressure gas or pressure measuring cylinder (not shown) during by work infeeds gas in valve and the container 4.In like manner, liquid is then derived from the axle pipe 16 of valve 1 and connector, and the tube among above-mentioned axle pipe 16 and the figure on the appropriate location is filled in a (not shown) and is connected.
The elastomeric material that surface treated first ring stiffener 17 (for example ring stiffener of stainless steel) that has lining cement is embedded valve collar 2 coaxially is for example in the polysulphide rubbers.
The inward flange district 19 that be clamped on the elastomeric material of valve collar 2 by a part, a part of crimping encases first ring stiffener 17 for example stainless second ring stiffener 18 is fixed on the valve collar 2.
Two ring stiffeners 17 and 18 stress that the axle pipe 16 that is used to strengthen valve collar 2 and bear connector produces when opening valve that combines.
The shape of first ring stiffener 17 is as a plate that has bottom 20 and annular lip 21, and described flange 21 stretches into the distance of one section weak point from the bottom of the protruding circle 22 of valve collar 2.
Fig. 3 illustrates the backplan of ring stiffener 17.On ring 17, make a plurality of transverse holes 23, be used to disconnect the joint between two parts elastomeric material of ring stiffener 17 both sides of valve collar 2.
The flange 21 of ring stiffener 17 is divided into 3 circular fan-shaped section 24, and every section diameter is greater than the diameter of the opening 25 of valve seat 8.Circular fan-shaped section 24 is separated by 3 curved recessed portion 26 again.In the time of in valve collar 2 is inserted valve 1, each above-mentioned curved recessed portion 26 is shorter with the distance of axis 27 than the edge 28 of the opening 25 of distance valve seat 8 with the distance of the axis 27 of valve.
Figure 4 and 5 are illustrated in the part amplification view of valve collar 2 when working under the superpressure that is higher than permissible value.
At first, the pressure of superelevation forces the opening 25 of the main portion of the protruding circle 22 of the elastomeric material of valve collar 2 by valve seat 8, till the circular fan-shaped section 24 of ring stiffener abuts against the bottom surface of valve seat 8.
At last, the opening 25 of valve seat 8 was also upwards pressed in the bottom 20 of valve collar.Its protruding circle is then blocked by valve seat 8, thereby makes valve collar 2 become shape shown in Figure 4.
As previously mentioned, 22 times the skim elastomeric material is only arranged at the protruding circle of valve collar, so under this material stress that superpressure produces in container and the pulling force between the elastomeric material on protruding circle of valve collar and the valve seat and in the recessed groove 26.And, because the edge of groove 26 is sharp keen, so when above-mentioned elastomeric material enters groove, the elastomeric material that is arranged in groove will be partially or even wholly cut on the groove limit.
Consider the situation of each side, the result of said process is exactly that elastomeric material in the groove deforms, thereby forms opening 29 in groove, and gas just flows along direction shown in the arrow by this opening 29.Therefore, the overvoltage in the container is removed.
Therefore, under predetermined superpressure value, valve of the present invention plays a kind of effect of highly effective safety valve.
In above-mentioned and embodiment shown in the drawings, valve collar 2 has second ring stiffener 18 that is positioned at face outside first ring stiffener 17, and this ring stiffener 18 only is to be stuck on the elastomeric material part of valve collar 2.When valve collar 2 distortion, the protruding circle of its elasticity will be forced to leave ring stiffener 18, as shown in Figure 2.
It is also noted that in above-mentioned connection the function that valve of the present invention has a safety valve does not depend on the setting of second ring stiffener 18, and other can not belong in the scope of the present invention with the embodiment of the valve collar 2 of above-mentioned ring stiffener yet.
In addition, the embodiment of the ring stiffener 17 that illustrates above and illustrate only is used to illustrate example of the present invention.Therefore, the neighboring of valve collar can be designed to many other forms, can have greater or less than 3 recesses, and each recess might not be a curved surface, and the peripheral fan-shaped section between the recess is also not necessarily circular.
