Abstract
The utility model relates to a high temperature and high pressure non-wearing ball valve, which comprises a valve cover, a valve body, a valve rod, an open and close part, a bracket and a drive device for the valve rod. The bracket is arranged on the valve cover and the valve rod is connected with the open and close part in a transmission manner. The open and close part is composed of two eudipleural ball petals. A wedge part is fixedly connected with the lower end of the valve body, with is fixed provided with an end cover. The planes of the two petals cling to the sloped surface of the wedge. The lower ends of the petals are respectively provided with an axial position projection, accordingly, a groove is arranged on the end cover to match with the projection. A synchronous contracting part is arranged on the wedge to be fixedly connected with the valve rod. The upper end of the ball petal is sleeved in the middle of the synchronous contracting part and the wedge. A bended guide channel is arranged on the upper end of the valve rod, with a guide pin on the bracket. The guide pin is positioned in the guide groove which controls the movement direction of the valve rod. The utility model has the advantages of long service life and liable sealing performance, and can be used in pipes of high temperate and high pressure.
Description
Technical field:
The utility model relates to a kind of valve, relates in particular to a kind of ball valve.
Background technique:
As everyone knows, ball valve is a kind of valve commonly used, generally comprise valve body, valve rod, open-shut device, valve gap etc., be provided with stuffing box packing between valve gap and the valve rod, open-shut device is a spheroid, and valve rod and spheroid are in transmission connection, and rotating around the valve body center with spheroid reaches the purpose of opening and closing, ball valve is mainly made cut-out, throttling, distribution and change media flow direction usefulness on pipeline, have switch advantage fast.Because of the valve seat in spheroid and the valve body rubs when the switch, wearing and tearing all take place and ball valve were lost efficacy in spheroid and valve seat easily.Especially can not adapt to the requirement of high-temperature and pressure pipeline to ball valve life-span and Security.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of life-span length and the good High Temperature High Pressure of Security not to have the wearing and tearing ball valve.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: High Temperature High Pressure does not have the wearing and tearing ball valve, comprise valve gap, valve body, valve rod, open-shut device, support and valve rod driving device, support be installed in valve gap above, valve rod and open-shut device are in transmission connection, described open-shut device is made of two symmetrical ball clacks, fixedly connected with wedge in the lower end of valve rod, lower end at valve body is installed with end cap, the plane of two ball clacks is close on the inclined-plane of wedge, the lower end of ball clack is provided with the axially locating projection, correspondingly, on end cap, be provided with groove and projection is complementary, also be provided with the body that contracts synchronously and fixedly connected with valve rod on wedge, the upper end of ball clack is enclosed within contracts between body and the wedge synchronously; Be provided with the guiding groove of bending in the upper end of valve rod, correspondingly be provided with guide finger on support, guide finger places the guiding groove of control valve rod moving direction.
The beneficial effects of the utility model: because spheroid is made of two symmetrical ball clacks, during unlatching, valve rod moves upward earlier and rotates, and under the effect of valve rod, ball clack is withdrawn earlier and afterwards rotated, just in time opposite when closing, ball clack rotates the back lock sealing earlier, and the sealing coupling mechanism force can be regulated as required, in the whole switching process, relative friction does not take place with valve seat in ball clack, thereby has long and reliable sealing advantage of life-span.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion partial enlarged drawing of Fig. 1.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As shown in the figure, High Temperature High Pressure does not have the wearing and tearing ball valve, comprise valve gap 1, valve body 5, valve rod 4, open-shut device, support 12 and valve rod driving device 3, support 12 be installed in valve gap 1 above, valve rod 4 is in transmission connection with open-shut device, described open-shut device is made of two symmetrical ball clacks 2, fixedly connected with wedge 6 in the lower end of valve rod 4, be installed with end cap 7 in the lower end of valve body 5, the plane of two ball clacks 2 is close on the inclined-plane of wedge 6, the lower end of ball clack 2 is provided with axially locating projection 8, correspondingly, be provided with groove 9 and be complementary with projection 8 on end cap 7, also be provided with the body 10 that contracts synchronously and fixedly connected with valve rod 4 on wedge 6, the upper end of ball clack 2 is enclosed within contracts between body 10 and the wedge 6 synchronously; Be provided with the guiding groove 11 of bending in the upper end of valve rod 4, correspondingly be provided with guide finger 13 on support 12, guide finger 13 places the guiding groove 11 of control valve rod 4 moving direction.Valve rod driving device 3 comprises Stem Mut 14, handwheel 15 and gland 16, and Stem Mut 14 is connected with support 12 axial restraints by gland 16, radially flexibly connects, and handwheel 15 is fixedlyed connected with Stem Mut 14.
Its working procedure is as follows: in the time of opening ball valve, rotate handwheel 15, drive valve rod 4 and move along guiding groove 11, promptly rise earlier and afterwards rotate, when valve rod 4 rises, two ball clack 2 withdrawals, throw off with the sealing seat of valve body 5, drive by wedge 6 by valve rod 4 again and open ball valve after two ball clacks 2 rotate; When closing ball valve, its process is opposite with unlatching, and two ball clacks 2 rotate rear distractions earlier, still close no matter open, and has all avoided the sealing seat of ball clack 2 and valve body 5 that pivoting friction is arranged.
