Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a low temperature ball valve, as shown in fig. 1-4, a low temperature ball valve, including hand wheel 4, valve rod 3, valve body 1, valve gap 2 and be located the valve ball 11 of valve body 1, valve body 1 is equipped with passageway 12 on the both sides inner wall that corresponds with valve ball 11 positions, and the both ends opening part of shown passageway 12 is equipped with the sealed lid 6 with the 1 outside threaded connection of valve body, passageway 12 is equipped with breach 121 with the position in the inner wall outside, the bottom is equipped with recess 122 in the breach 121, passageway 12 still includes the annular cover 5 with the 12 inner wall shape looks adaptations of passageway, be equipped with the cooperation piece 51 with recess 122 interference fit on the annular cover 5, shown cooperation piece 51 is the rubber material, and the outer end of annular cover 5 is equipped with the kink 52 of inside bending type. Magnets are embedded at the bottom of the groove 122 and at one end of the matching block 51 facing the groove 122. The center position of the outer surface of the sealing cover 6 is provided with a hexagonal prism 61. The side walls of the hexagonal prism 61 are provided with a stepped hole 611 extending transversely therethrough. Two springs 7 are circumferentially distributed on the side of the annular sleeve 5 facing the sealing cover 6. The side walls of the hexagonal prism 61 are provided with a stepped hole 611 extending transversely therethrough.

The working principle of the utility model is, as shown in fig. 1 and fig. 3, the valve ball 11 is linked together with the fluid passage 12 under the normal use state, is used for sealed disk seat (not marked in the figure) between valve ball 11 and the valve body 1, after being plugged up by impurity when valve ball 11, can rotate hand wheel 4 to drive valve rod 3 and rotate, make valve ball 11 rotate 90 degrees, valve ball 11 can take some rivers out at the pivoted in-process. As shown in fig. 2 and 4, the passage 12 is communicated with the interior of the valve ball 11. Rotate hexagonal prism 61 with the spanner, thereby unscrew sealed lid 6 from valve body 1, valve ball 11 has formed the passageway 12 that both ends all external intercommunication, earlier after the moisture discharges in passageway 12, stretch into valve ball 11 with burnisher through passageway 12 again, scrape down toward one side direction with the impurity in the valve ball 11, thereby the impurity that is scraped down also can be pushed to in passageway 12 and fall on annular cover 5 and pile up impurity, annular cover 5 is fixed in on the inner wall of passageway 12 through the buckle cooperation, after the cleanness is accomplished, thereby can stimulate kink 52 on the annular cover 5 and tear annular cover 5 down alone from the inner wall of passageway 12, wash the impurity on the annular cover 5, also can change alone after annular cover 5 damages. Has the effects of convenient cleaning and convenient operation, and improves the working efficiency.

In the above structure, when the annular sleeve 5 needs to be taken out, the annular sleeve 5 can be pulled out after the bending part 52 is pinched, so that the annular sleeve 5 can be detached more conveniently and quickly. Through setting up magnet, cooperation piece 51 can be laminated tighter with recess 122, prevents that annular sleeve 5 from dropping, and valve body 1 is also the metal material moreover, can adsorb each other with magnet. When covering sealed lid 6, spring 7 compresses, can extrude sealed lid 6 and annular cover 5 respectively to both sides, and after sealed lid 6 received axial extrusion force, the screw-thread fit between sealed lid 6 and the valve body 1 was inseparabler, has increased sealed effect, and annular cover 5 received the extrusion force to recess 122 direction, and the recess 122 between the complex inseparabler. By providing the stepped hole 611, a handle-like cleaning tool can be placed on the hexagonal prism 61 through the stepped hole 611, and can be easily taken when needed.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
