Detailed Description
Specific embodiments of the present invention will be described below with reference to fig. 1 to 3.
(as shown in fig. 1) the titanium alloy overflow prevention float valve storage vessel, including the storage vessel 1, it should be understood that any vessel structure that can perform the storage function is suitable for this case.
The top end of the storage container 1 is provided with a fluid medium injection port 2; the fluid medium injection port 2 is of a hollow circular tube structure which is straight up and down. The hollow circular tube which is straight up and down determines the shape and the vertical state of the fluid medium injection port 2. So that the lower end of the hollow circular tube of the fluid medium injection port 2 is used as a sealing valve seat.
The center of the fluid medium injection port 2 is matched with a coaxial gap to fixedly support and install the guide post 3.
The guide post 3 is preferably made of a titanium alloy material to improve corrosion resistance. The coaxial gap of the fluid medium injection port 2 is matched with the fixed supporting and mounting guide column 3: the gap adaptive structure is adopted, on one hand, the guide post 3 can only be vertically arranged; on the other hand, the guide pin 3 has a clearance which can be large enough to allow the fluid medium to be continuously injected from the clearance of the fluid medium inlet 2 into the storage container 1 as shown in fig. 1.
The upper end of the guide column 3 extends out of the fluid medium injection port 2 and is fixedly supported and installed in a fixed position, so that sufficient injection gaps and spaces are reserved, and injection operation is facilitated.
The lower end of the guide column 3 is vertically and fixedly connected with the bottom end of the inner side wall of the storage container 1 into a whole. The orientation of the guide post 3 is defined, i.e. the guide post 3 is vertically fixed supported.
And a sealing ball 4 is coaxially, slidably, hermetically and fittingly arranged on the outer side of the column body of the guide column 3. I.e. the sealing ball 4 is vertically displaced up and down along the guide post 3.
And polishing the outer cylindrical surface of the guide column 3. Namely, the sealing ball 4 is coaxially and hermetically matched with the guide column 3 in a sealing way with high precision, so that the sealing ball 4 is vertically lifted along the guide column 3 under the action of buoyancy.
The diameter of the sealing ball 4 is larger than the inner diameter of the lower end opening end of the fluid medium injection inlet 2, so that a ball sealing structure is realized. That is to say: the sealing ball 4 is used for sealing and blocking the lower end of the fluid medium injection port 2.
In the above embodiment, further: the inner side wall of the lower end opening end of the fluid medium injection port 2 is provided with an inner conical surface 2-1 which is small at the top and big at the bottom in the orientation shown in figure 1. The internal conical surface 2-1 is used for 4-position cut-off sealing of the sealing ball.
The inclination of the inner conical surface 2-1 is equal to that of the sealing surface of the sealing ball 4.
The inner conical surface 2-1 is adopted for positioning and sealing, so that the sealing reliability is favorably improved. Wherein the slope of the inner conical surface 2-1 is equal to the slope of the sealing conical surface of the sealing ball 4 (as shown in fig. 2), i.e. the positioning sealing of the sealing ball 4 on the inner conical surface 2-1 is realized by adopting surface contact sealing instead of line contact sealing, and the reliability of the anti-overflow cut-off type sealing is improved by increasing the sealing contact area.
The buoyancy of the sealing ball 4 is always larger than the gravity borne by the sealing ball 4; so that the anti-overflow sealing function of the floating ball of the sealing ball 4 can be realized when different fluid media are loaded.
The outer surface of the ball body of the sealing ball 4 is made of a titanium alloy material subjected to polishing treatment, so that the erosion resistance of a fluid medium on the surface of the ball body of the sealing ball 4 is improved, and the service life of the stop valve is prolonged.
In the above embodiment, preferably: the surface roughness Ra of the ball body of the sealing ball 4 is 0.0762-0.0127 mu m and comprises a top value. Thereby improving the self-cleaning performance of the sealing ball 4 and avoiding the liquid hanging problem of the sealing ball 4.
In the above embodiment, further: the sealing ball 4 (shown in fig. 3) is composed of a titanium alloy ball shell 401 with a spherical structure and a sliding sleeve 402 with a straight cylindrical structure; on one hand, the buoyancy of the sealing ball is increased, and on the other hand, the consumption of titanium materials is saved, and the cost is controlled.
In addition, the sliding sleeve 402 is fixedly connected with the titanium alloy spherical shell 401 in a coaxial sealing manner, specifically, the sliding sleeve can be fixedly connected in a sealing manner in a bonding manner, so that leakage at the matching connection position is prevented.
The sliding sleeve 402 is connected with the guide column 3 in a coaxial sliding sealing matching mode in a sleeved mode, and the sealing and leakage-preventing functions are achieved in a finish machining high-precision matching mode.
The utility model discloses a theory of operation does: the fluid medium is injected from the fluid medium inlet 2 of the storage container 1 toward the small flow and low pressure in the storage container 1. Because the buoyancy of the sealing ball 4 is always greater than the gravity of the sealing ball 4, the sealing ball 4 always floats above the liquid level and does not deviate from the guide column 3 to vertically float and rise along a straight line. Along with the continuous injection of the fluid medium, the liquid level continuously rises, the pushing sealing ball 4 continuously moves upwards along the pushing part 3 until the small upper part of the sealing ball 4 is attached to the inner conical surface 2-1 at the opening at the lower end of the fluid medium injection port 2, and therefore the stopping function of the fluid medium injection port 2 is achieved. At the same time of stopping sealing, the fluid medium injected by small flow can be partially gathered at the upper half part of the sealing ball 4 of the fluid medium injection port 2, and the pressure of the injected fluid cannot push the sealing ball 4 to move downwards, so that the reliability of the sealing position of the sealing ball 4 on the inner conical surface 2-1 is maintained. It should be noted that: because the liquid level in the storage container 1 does not exceed the horizontal center line position of the sealing ball 4 all the time, the automatic anti-overflow stop sealing function of the injected liquid is realized when the fluid medium is injected from the fluid medium injection port 2. Even if the storage container 1 is in a shaking and conveying state, the sealing ball 4 does not deviate from the inner conical surface 2-1 due to the linear guiding effect of the guide column 3, and the sealing and blocking stop state is always kept, so that the sealing reliability of overflow prevention is ensured.
From the above description it can be found that: the utility model discloses a titanium alloy ball sealer is sealed, satisfies special fluid medium's corrosion-resistant user demand, and then improves valve life.
The utility model discloses sealed ball sphere finish reaches the requirement, and sealed ball sphere surface itself possesses the self-cleaning function that special fluid is situated between, avoids the hanging liquid, guarantees the sealing reliability.
The utility model discloses the ball sealer provides the location direction through the guide post, and the ball sealer is just all the time to the fluid medium filling opening removal that rises, treats that fluid medium liquid level propelling movement seals the floater and rises when supporting fluid medium filling opening lower extreme, realizes the anti-overflow of fluid medium filling opening and cuts sealing function, stops the filling simultaneously, does the fluid medium that the unnecessary injection of suction ball sealer upper half slightly, accomplishes the autonomous and cuts sealing function.
To sum up, the utility model discloses simple structure, sealed guide orientation of automatic ending type of ball sealer 4 is reliable, and ball sealer 4 has self-cleaning nothing and hangs the liquid sealing function, and ball sealer corrosion resisting property is good, and is longe-lived.
