Abstract
The utility model discloses an upper mounting type ball valve which comprises a valve body, a valve seat and a ball body. An O-shaped seal ring and a spring are arranged between the valve body and the valve seat, a chute is opened in the valve body, a knob is arranged in the chute in a penetrating mode, and the inner end of the knob is connected with the valve seat through a connection structure. According to the upper mounting type ball valve, the chute is opened in the valve body, the knob is arranged in the chute, external threads are opened in the valve seat, the knob is connected with the valve seat, and the knob can drive the valve seat to move by rotation, accordingly, the ball body can be mounted conveniently in the valve seat, and the processing of the valve seat is convenient.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of upper-mounting type ball valve.
Background technique
One of widely used valve of ball valve, its working principle is the same with stopcock, all is to make valve opening and closing by rotary spool, but lighter than stopcock switch, relative volume is little, can make big-diameter ball valve.Ball valve sealing is reliable, and is simple in structure, easy to maintenance, and sealing surface and the spheroid closed state of being everlasting is difficult for by the medium erosion, thereby is widely used in industries such as oil, chemical industry, metallurgy.
Referring to shown in Figure 1, the spheroid 3 that existing ball valve generally comprises valve body 1, valve seat 2 and seals, be provided with spring 4 and O-ring seals 5 between valve body 1 and the valve seat 2, the spheroid of ball valve is fixed, do not produce movement behind the pressurized, after valve seat is subjected to hydrodynamic pressure, produce mobile, can be pressed on the spheroid, to guarantee sealing.Valve base inner wall generally also offers an annular groove 6, when needs assembling spheroid, holds annular groove with L shaped drag hook 7, and the backward valve body direction of active force that makes valve seat overcome spring moves, and then spheroid is put into two symmetrical valve seats.But because the difficult processing of the annular groove in the valve seat, and L shaped drag hook is difficult to aim at annular groove when assembling, causes ball valve assembling difficulty.
Summary of the invention
The utility model purpose provides a kind of upper-mounting type ball valve, and by the improvement to structure, so that valve seat processing is comparatively convenient, and the assembling of ball valve is also comparatively convenient.
The technical solution of the utility model is: a kind of upper-mounting type ball valve, comprise valve body, valve seat and spheroid, described valve body and described valve base chamber are provided with O-ring seals and spring, offer chute on the described valve body, run through being provided with a knob in the described chute, described knob the inner is connected with described valve seat through linkage structure.
Further technological scheme, described linkage structure comprises the outside thread of offering on the described valve seat, described valve seat is connected with described knob through outside thread.
Further technological scheme, the outside thread of offering on the described valve seat is square threaded form.
In the technique scheme, this ball valve is made of valve body, valve seat and spheroid, and O-ring seals and spring are set between valve body and the valve seat, offers chute on the valve body, and knob runs through chute, offers outside thread on the valve seat, and knob the inner is connected with valve seat by outside thread.During knob, the active force that the drive valve seat overcomes spring moves to valve body, thereby spheroid can be put into two symmetrical valve seats, and owing to adopting square threaded form to connect, also has auto-lock function.
The utility model has the advantages that:
1. the utility model arranges knob by offering chute at valve body in the chute, offers outside thread on the valve seat, knob is connected with valve seat through outside thread, knob can drive valve seat and move, thereby so that spheroid can be packed into easily in the valve seat, and the processing of valve seat is also comparatively convenient;
2. the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is ball-valve structure schematic diagram in the prior art;
Fig. 2 is the utility model embodiment one structural representation.
Wherein: 1, valve body; 2, valve seat; 3, spheroid; 4, spring; 5, O-ring seals; 6, annular groove; 7, L shaped drag hook; 8, valve body; 9, valve seat; 10, spheroid; 11, O-ring seals; 12, spring; 13, chute; 14, knob.
Embodiment
Embodiment one: referring to shown in Figure 2, a kind of upper-mounting type ball valve, comprise valve body 8, valve seat 9 and spheroid 10,9 of described valve body 8 and described valve seats are provided with O-ring seals 11 and spring 12, offer chute 13 on the described valve body, run through being provided with a knob 14 in the described chute 13, the outside thread of offering on the described valve seat, described valve seat is connected with described knob through outside thread.
Ball valve is in when assembling, and rotation is rotated and can be driven active force that valve seat overcomes spring B direction in the figure and move, but and then spheroid put into two symmetrical valve seats along the A direction, the assembling of whole ball valve is comparatively convenient.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
