Abstract
The utility model relates to a ball valve. The utility model overcomes the defect that valve base of the ball valve is easy to be scratched by crystal particles in the medium. The utility model comprises a handle, a valve rod, a valve body, a valve cover, a valve seat, a ball-body valve core and a resistor ring which is designed on the inner side of the valve seat. Consequently, the prevention of the direct contact of the crystal particles and the soft seal is obtained. The utility model has the advantages of good sealing performance, long service life, etc.
Description
The utility model relates to a kind of ball valve, the ball valve of especially a kind of anti-crystal grain and impurity.
At present, the ball valve that is used for fields such as metallurgy, oil, chemical industry, pharmacy.The general soft sealing ball valve that adopts, promptly the valve seat of this valve is a soft seal.When crystalline solid particle or impurity are arranged in the medium, use this ball seat to be easy to scratch or abrasion serious, to making the ball valve premature failure, the anti-crystal property of this thus ordinary ball valve is poor, the life-span is short.As National Standard General valve flange and to welding steel ball valve the ball valve of being introduced in (GB12237-89).
The purpose of this utility model provides a kind of ball valve that can prevent dielectric crystal scratch soft seal valve seat effectively, thereby overcomes the deficiencies in the prior art part.
For achieving the above object, technical solution of the present utility model is: set up the resistance crystal rings in the inboard of valve seat one, make the crystal impurity in the medium can not be directly near the soft seal valve seat.For realizing that this scheme formation of the present utility model is; It comprises handle, valve rod, valve body, valve gap, valve seat, spheroid spool, valve seat is positioned in the body cavity by valve gap, the spheroid spool again by the valve seat positioning support on the valve rod axis of symmetry of body cavity, and closely contact with the soft seal valve seat, forming good soft seal, the soft seal valve seat is embedded in the metal seat valve, valve rod is fixed in the valve-rod cavity of valve body, its end and spheroid spool link, and the other end is connected with handle, and handle drives the rotatable several angle of spheroid spool by valve rod; Resistance crystalline substance ring has together also been set up in the inboard of valve seat, and the brilliant ring of resistance forms hard sealing by the butterfly spring of carrying on the back end with the spheroid spool and contacts, and forms two seals like this, i.e. the hard sealing of anti-crystal and the soft seal of anti-fluid.
Also be provided with the brilliant groove of appearance on the brilliant ring of resistance of the present utility model one.
Because the utility model has been set up the brilliant ring structure of resistance in the inboard of valve seat, and on the brilliant ring of resistance, also opened and held brilliant groove together, so that the crystal grain of runner medium or impurity are blocked in the brilliant ring of resistance, promptly be that trace prevents that crystal grain or impurity hinder crystal face by internal layer in the medium, also can only be contained in the brilliant groove, this has just guaranteed that the soft seal valve seat is not scratched, and keeps good sealing property muchly; Again owing to the formed hard sealing of setting up that hinders brilliant ring, so the fireproof performance of this valve is more superior.This shows that it is wide to the utlity model has using scope, good airproof performance, characteristics such as the life-span is long.
Below in conjunction with accompanying drawing the structure of model utility is done detailed explanation:
In the accompanying drawing, Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the brilliant ring of resistance;
As shown in drawings, the utility model comprises handle [11], valve rod [10], valve body [1], spheroid spool [7] and a pair of valve gap [2], valve seat [5,6] and the brilliant ring of resistance [8], valve seat is positioned in the body cavity by valve gap, the spheroid spool again by a pair of valve seat positioning support on the valve rod axis of symmetry of body cavity, valve seat is made up of soft seal valve seat [6] and metal seat valve [5], the soft seal valve seat is embedded in the metal seat valve, the spheroid spool closely contacts with the soft seal valve seat, form good soft seal, the inboard of valve seat is the brilliant ring of one resistance, resistance crystalline substance ring back of the body end has butterfly spring [3] to support adjusting, make the brilliant ring of resistance form hard sealing with the spheroid spool and contact, also have the brilliant groove [12] of appearance on the resistance crystal face [13] of the brilliant ring of resistance one, the back of the body end of valve seat also has one pad [4], valve rod is fixed in the valve-rod cavity of valve body, one end of valve rod is inserted in the square groove [9] on the spheroid spool, and the other end is connected with handle, handle with sleeve, drive the spheroid valve core rotation by valve rod, to realize the opening and closing of ball valve.
Claims (2)
1, a kind of ball valve, it comprises handle [11], valve rod [10], valve body [1], valve gap [2], valve seat [5,6] and spheroid spool [7], valve seat is positioned in the body cavity by valve gap, the spheroid spool again by the valve seat positioning support on the valve rod axis of symmetry of body cavity, and closely contact with soft seal valve seat [6], form good soft seal, the soft seal valve seat is embedded in the metal seat valve [5], valve rod is fixed in the valve-rod cavity of valve body, its end and spheroid spool link, the other end is connected with handle, handle drives the rotatable several angle of spheroid spool by valve rod, brilliant encircle [8] of resistance have together also been set up in the inboard that it is characterized in that valve seat, and the butterfly spring [3] that the brilliant ring of resistance is held by the back of the body forms hard sealing with the spheroid spool and contacts.
2, ball valve according to claim 1 is characterized in that also being provided with on the anti-crystal the brilliant groove [12] of appearance one.
