Abstract
The utility model relates to a ball valve, in particular to a four-way ball valve comprising a valve body, a valve seat, a ball body, a valve rod and an operation mechanism, wherein four portholes are arranged on the valve body and each porthole is connected with a flange; and a sealing part matched with the ball body for sealing is arranged at the front end of the valve seat. The four-way ball valve is characterized in that the valve seat is arranged in a channel of the valve body; and a compression spring is arranged between the valve seat and the end face of the flange. With the compression spring arranged between the valve seat and the end face of the flange, the sealing capability of the sealing part of the valve seat can be compensated in case of wearing; moreover, the compression spring can be conveniently changed after demounting the flange in case of fatigue failure caused by repeated use; and the operation is very convenient.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of four way ball valve.
Background technique
In the existing four way ball valve, its valve seat does not have compensate function usually, promptly after wearing and tearing appear in the sealing surface of valve seat, just valve seat can only be pulled down again sealing surface is changed, and operation is trouble very.
The model utility content
The purpose of this utility model is to solve the deficiency of existing four way ball valve, and provides a kind of valve seat to have the four way ball valve of compensate function.
The purpose of this utility model is achieved by the following technical solution: a kind of four way ball valve, comprise valve body, valve seat, spheroid, valve rod and operating device, on valve body, be provided with four passwaies, respectively be connected with flange at each place, passway, front end at valve seat is provided with the Sealing that is sealed and matched with the spheroid formation, be characterized in: described valve seat is installed in the passage of valve body, is provided with pressure spring between the end face of valve seat and flange.
Further, valve seat before and after described valve seat includes, the outside, rear end of preceding valve seat is provided with the ring-type short slot, and the corresponding annular boss that is provided with of the front end of described rear valve base is placed in this ring-type short slot, annular boss and, ring-type jar groove and conduit wall constitute a cavity volume, is filled with graphite in the cavity volume.
Further, described Sealing is a teflon seal.
Beneficial effect: the utility model is owing to be provided with pressure spring between valve seat and end face of flange, therefore behind the sealing part abrasion of valve seat, can compensate it, in addition, when fatigue failure appears in pressure spring in using process repeatedly, can unload lower flange easily and just can change pressure spring, operation is very easy.
Description of drawings
Fig. 1 is the utility model four way ball valve embodiment's a structural representation
Fig. 2 is the I place enlarged view of Fig. 1
Embodiment
Now in conjunction with the accompanying drawings mode of execution of the present utility model is further described:
As shown in Figure 1 and Figure 2, the embodiment of a kind of four way ball valve of the utility model, comprise valve body 3, valve seat 4, spheroid 5, valve rod 2 and operating device 1, this operating device 1 can for pneumatic, surge or variety of way such as manual, on valve body 3, be provided with four passwaies, respectively be connected with flange 7 at each place, passway, front end at valve seat 4 is provided with the teflon seal 43 that is sealed and matched with spheroid 5 formations, described valve seat 4 is installed in the passage of valve body 3, is provided with pressure spring 6 between the end face of valve seat 4 and flange 7.After Sealing 43 wearing and tearing of valve seat 4, can utilize this pressure spring 6 that it is compensated, in addition, when fatigue failure appears in pressure spring 6 in using process repeatedly, can unload lower flange 7 easily and just can change pressure spring, operation is very easy.
In the diagram, valve seat 41,42 before and after described valve seat 4 includes, the outside, rear end of preceding valve seat 41 is provided with ring-type short slot 411, the corresponding annular boss 421 that is provided with of the front end of described rear valve base 42 is placed in this ring-type short slot 411, annular boss and, ring-type jar groove and conduit wall constitute a cavity volume, is filled with graphite 8 in the cavity volume.Realize sealing between valve seat and the valve body by plumbago, thus applicable to the high temperature media occasion, and adopting the mode of forward and backward valve seat, dress graphite is also very convenient.
