Abstract
The utility model discloses an anti-scratching wear-resistant ball valve, and relates to the field of valves. The conventional ball valve usually adopts a hard-seal valve seat, and the sealing surfaces of a valve element and the valve seat easily contact a medium, and are easily corroded, so that the conventional ball valve is short in service life and high in use cost. The anti-scratching wear-resistant ball valve comprises a ball core, a valve seat, a valve body, a valve cover and a valve rod, wherein the valve body is provided with two medium circulation channels; the valve seat is arranged at internal openings of the medium circulation channels, and is in close fit with the ball core; a double-sealing ring is arranged on the sealing working surface, which is combined with the ball core, of the valve seat; and a transit circular arc is respectively reserved on the main sealing surface, which contacts the ball core, of the double-sealing ring and the secondary sealing surface, which contacts the ball core, of the double-sealing ring. According to the ball valve, the double-sealing ring is used for sealing, so that the abrasion and damage of granular impurities to the sealing surfaces are reduced; and moreover, regardless of whether the ball valve is opened or closed, the sealing surfaces of the ball core and the valve seat are separated from a medium, so that the service life of the ball valve is prolonged.
Description
Technical field
The utility model relates to valve, is specifically related to a kind of anti-scraping wear resistance ball valve.
Background technique
The hard seal valve seat of the many employings of traditional ball valve; The structure of its seal ring is as shown in Figure 3 usually, and spool is prone to contact with medium and be corroded with the sealing surface of valve seat, and when bad particle gets into the sealing surface of spheroid and valve seat; Hard impurity in the medium also can scratch sealing layer; Shorten ball valve working life, increased user cost, do not meet the requirement of setting up conservation-minded society.
Summary of the invention
The purpose of the utility model is that the valve seat and the spool that solve existing ball valve existence are hard, contacts easy to wear, corrosion for a long time, ball valve short problem in working life.
The utility model adopts technological scheme following:
A kind of ball valve; Comprise ball core, valve seat, valve body, valve gap, valve rod; Described valve body has two MEDIA FLOW circulation passage, and the internal orifice of MEDIA FLOW circulation passage is provided with valve seat, and valve seat and ball core closely cooperate; The sealed working face that described valve seat combines with the ball core is provided with the double density seal, the primary sealing area that this double density seal contacts with the ball core, with secondary sealing area that valve seat contacts on all offer transition arc.
The utlity model has following advantage:
1, sealing is reliable.Adopt double density seal sealing, when bad foreign material particle was arranged in the medium, the foreign material particle was when the primary sealing area place that contacts with valve seat through the ball core; The foreign material particle can be trapped in transition arc, has reduced wearing and tearing and the destruction of foreign material particle to sealing surface accordingly, the working life of having improved ball valve; No matter and be to open or close; The sealing surface of ball core and valve seat all separates with medium, so medium can the etch valve sealing face, the ball valve long service life.
2, easy to operate, open and close rapidly, from the standard-sized sheet to the full cut-off, need only rotation 90.At a distance, control is convenient.
The utility model also has the beneficial effect that the ball valve resistance is low, simple in structure, compact, weight is lighter.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment
A kind of ball valve; Comprise ball core 1, valve seat 2, valve body 3, valve gap 4, valve rod 5, described valve body 3 tops are provided with valve gap 4, and valve body 3 inside have two MEDIA FLOW circulation passage; The internal orifice of MEDIA FLOW circulation passage is provided with valve seat 2; Valve seat 2 closely cooperates with ball core 1, and the sealed working face that described valve seat 2 combines with ball core 1 is provided with double density seal 6, the primary sealing area that this double density seal 6 contacts with ball core 1, with secondary sealing area that valve seat 2 contacts on all offer transition arc 7.Ball core 1 top is connected with valve rod 5, and valve rod 5 tops are provided with handle 8.
From the above mentioned, the utility model adopts double density seal 6 sealings, when bad foreign material particle is arranged in the medium; The foreign material particle is through ball core 1 during with primary sealing area place that valve seat 2 contacts; The foreign material particle can be trapped for 7 li at transition arc, has reduced wearing and tearing and the destruction of foreign material particle to sealing surface accordingly, the working life of having improved ball valve; No matter and be to open or close; The sealing surface of ball core 1 and valve seat 2 all separates with medium, so medium can the etch valve sealing face, prolongs the ball valve purpose in working life thereby reached.
The utility model only describes with the foregoing description; The structure of each parts, the position is set and connects and all can change to some extent; On the basis of the utility model technological scheme; All improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside the protection domain of the utility model.
