Abstract
The utility model relates to a high temperature and high pressure resistant two-way zero wear ball valve. The utility model is composed of a valve body, a valve cover and a control end, wherein, a spherical body and a valve seat are arranged in the valve body, the control end is assembled by a support sleeve, a support seat, a support block, a valve rod and a sealing piece, the support sleeve, the support seat and the support block are arranged in the valve cover, the sealing piece is arranged outside the valve cover, the lower end of the valve rod is connected with a bias groove arranged at the upper end of the spherical body, a sealing pad and a pressing cover of the sealing piece are arranged outside the middle position of the valve rod, and the upper position of the valve rod is provided with a slide groove. The end part of the valve rod is provided with a hand wheel sleeve and a hand wheel, the inner side of the hand wheel sleeve is provided with a bead ball which rotates and slides in the positioning manner, and the center of the end part of the hand wheel is provided with a rotating and positioning bolt of the spherical body. The utility model has the advantages of compact structure, zero wear, reliable seal, high temperature and high pressure resistance, quick opening and closing operation and portable operation.
Description
The utility model relates to a kind of two-way nothing wearing and tearing of high temperature high voltage resistant ball valve that is used for industries such as oil, chemical industry, electric power, metallurgy, papermaking.
Present employed ball valve can only be applicable under the normal temperature and pressure and to open and close, and when ducted fluid temperature (F.T.) and pressure are higher than normal temperature and pressure, produces hot affinity, opens and closes slowly, rotates that to turn round torch big, the operation effort; Spool produces friction with valve seat in rotation process, serious wear easily causes leakage; Easily accumulate medium in the valve body, hindered the rotation of spool, thereby can't in the high-temperature, high pressure fluid medium pipeline, install and use.
The purpose of this utility model provides the two-way nothing of a kind of high temperature high voltage resistant wearing and tearing ball valve, and it can keep good sealing property under the High Temperature High Pressure operating conditions, have do not deposit medium, do not have wearing and tearing, bidirectional flow is to, moment of torsion is little, operation is light, safe and reliable usefulness.
The purpose of this utility model is achieved in that the two-way nothing wearing and tearing of a kind of high temperature high voltage resistant ball valve, by valve body, valve gap and control end constitute, through hole spheroid and valve seat are housed in the valve body, it is characterized in that control end comprises the spider that is equipped with by the valve gap internal upper part, a bearing that be equipped with the bottom and a piece, the Sealing card of being lived admittedly by bolt that be equipped with in the outside seals, seal, pad, collar and the middle valve rod group that is equipped with are dressed up, valve rod lower end and spheroid upper end groove partially link, the outside, valve rod intermediate portion is provided with the Sealing pressure pad, packing, gland and sealing adjusting element pull bar and pin, it is connected with valve gap by nut, valve gap is affixed by bolt and spider, the valve rod upper part is provided with " the type concave slide groove; handwheel sleeve and handwheel are equipped with in the valve rod upper end; the handwheel sleeve lower inside is provided with pearl ball pin and the jackscrew that slides in the valve rod location; pearl ball pin end embeds in the concave slide groove of valve rod; reduce the power of holding tightly that valve rod slides up and down; inside upper part is provided with the pearl ball and the jackscrew of valve rod position rotating, and the holding down bolt of regulating spheroid rotational position degree is equipped with at center, handwheel end.Its working principle is as follows: shake handwheel, coupled valve rod moves in concave slide groove by location turn of positioning bead ball and pearl ball pin, and valve rod is up, prop up piece thereupon, bearing also moves up, because the both sides exchange top power effect of propping up piece makes bearing and spheroid off center, spheroid and valve seat produce the gap, valve rod half-twist then, spheroid and then changes 90 °, does not produce friction with valve seat, wearing and tearing have been reduced, its spheroid through hole is consistent with pipe diameter, is opening state, and medium can flow.Otherwise after 90 ° of rotations that reset of do earlier, valve rod is to lower slider, bearing moves down simultaneously, props up on a left side under the top power effect of piece, makes spheroid compress valve seat and is closed state, promptly cut off flowing of medium, the position degree of its spheroid rotation is regulated by the holding down bolt at center, handwheel end.
This model utility compact structure, sealing are reliable, no wearing and tearing, high temperature high voltage resistant, keying rapidly, operation is light, is the ideal product of replacement gate valve.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the two-way nothing wearing and tearing of a kind of high temperature high voltage resistant ball valve, by valve body (26), valve gap (10) and control end constitute, through hole spheroid (24) and valve seat (15) are housed in the valve body (26), its control end comprises the spider (22) that is equipped with by valve gap (10) internal upper part, a bearing that be equipped with the bottom (23) and a piece (25), what be equipped with in the outside seals (14) by the solid Sealing card firmly of bolt (9), seal (13), pad (12), collar (11) and the middle valve rod (3) that is equipped with are assembled into, valve rod (3) lower end and spheroid (24) upper end groove partially link, the outside, valve rod (3) intermediate portion is provided with Sealing pressure pad (5), packing (6), gland (4) and sealing adjusting element pull bar (20) and pin (21), it is connected with valve gap (10) by nut (19), valve gap (10) is affixed by bolt (7) and spider (22), valve rod (3) upper part is provided with " type concave slide groove (27); handwheel sleeve (28) and handwheel (16) are equipped with in valve rod (3) upper end; handwheel sleeve (28) lower inside is provided with the pearl ball pin (2) and jackscrew (8) that slides in the valve rod location; pearl ball pin (2) end embeds in the concave slide groove (27) of valve rod; inside upper part is provided with the pearl ball (18) and jackscrew (1) of valve rod position rotating, and the holding down bolt (17) of regulating spheroid rotational position degree is housed in handwheel (16) end in the heart.
