Abstract
The invention relates to a large-caliber upwardly-installed fixed ball valve. The large-caliber upwardly-installed fixed ball valve comprises a valve ball, a valve seat and a valve body, wherein the valve seat is arranged between the valve ball and the valve body. The large-caliber upwardly-installed fixed ball valve is characterized in that the valve seat comprises a fixing device body and a spring retainer and is of a split structure, a shoulder is arranged on the outer circumference of the fixing device body, outer threads are processed on the outer circumference of the tail portion of the shoulder, inner threads are processed inside the spring retainer, and the fixing device body and the spring retainer are connected though the threads in a matching and screwing mode. The large-caliber upwardly-installed fixed ball valve is simple in structure and low in production cost, the valve seat is of the split structure so that the fixed ball valve can be upwardly installed, then online maintenance of the fixed ball valve can be achieved, the time of work stopping and production stopping is shortened, and the economic loss is reduced.
Description
Technical field
The present invention relates to a kind of valve seat of upper dress formula fixing ball valve, especially relate to a kind of valve seat that is applied to fill on heavy caliber formula fixing ball valve, belong to valve design technical field.
Background technique
the advantages such as we know, the feature of the full diversion Design of fixing ball valve has resistance of medium little, easy to operate, quick are widely used on oil and natural gas pipeline.But conventional side-mounted fixing ball valve is when breaking down maintenance, and whole valve has to pull down from pipeline, the especially soldered valve that connects, in order to keep in repair valve, have to valve to cut down from pipeline, cause the relevant tube line length time to be stopped and stop production, cause heavy economic losses.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of can on-line maintenance, reduce on the heavy caliber of parking economic loss and fill formula fixing ball valve.
For achieving the above object, the present invention is achieved by the following technical solutions:
On heavy caliber, fill formula fixing ball valve, comprise valve ball, valve seat and valve body, described valve seat is arranged between described valve ball and valve body, it is characterized in that, described valve seat comprises retainer body and spring-leaf retainer two-part, for split-type structural, on the excircle of described retainer body, be provided with shoulder, on the excircle of the afterbody of described shoulder, be processed with outside thread, and the inside of described spring-leaf retainer is processed with internal thread, described retainer body and spring-leaf retainer screw connection by screw-thread fit.
Further, the end face of the spring-leaf retainer that described and valve body close on caves inward and is formed with rectangle assembling groove, be provided with cylindrical spring, and the two ends of described cylindrical spring contacts respectively in described rectangle assembling groove with valve body with spring-leaf retainer.
And be formed with ring-type rectangle groove on the end face of the retainer body that described and valve ball close on, in described ring-type rectangle groove, be provided with the seal ring that is used to form valve ball and retainer body sealing.
And on the outer circumferential face of described retainer body afterbody and between valve body, be also provided with O type circle and fire prevention graphite packing.
The invention has the beneficial effects as follows: the present invention is simple in structure, cost of production is low, by valve seat, be set to split-type structural, make fixing ball valve can form dress formula, and then can realize the on-line maintenance of fixing ball valve, reduce the parking off-time, reduced economic loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
In figure, main mark implication is as follows:
1, valve ball 2, seal ring 3, retainer body 4, spring-leaf retainer
5, cylindrical spring 6, O type circle 7, fire prevention graphite packing 8, valve body.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Fig. 1 is the structural representation of one embodiment of the invention.
As shown in Figure 1: on heavy caliber, fill formula fixing ball valve, comprise valve ball 1, valve seat and valve body 8, described valve seat is arranged between described valve ball 1 and valve body 8, described valve seat comprises retainer body 3 and spring-leaf retainer 4 two-part, for split-type structural, on the excircle of described retainer body 3, be provided with shoulder, on the excircle of the afterbody of described shoulder, be processed with outside thread, and the inside of described spring-leaf retainer 4 is processed with internal thread, described retainer body 3 and spring-leaf retainer 4 screw connection by screw-thread fit.
Wherein, the end face of the spring-leaf retainer 4 that described and valve body 8 close on caves inward and is formed with rectangle assembling groove, be provided with cylindrical spring 5, and the two ends of described cylindrical spring 5 contacts respectively in described rectangle assembling groove with valve body 8 with spring-leaf retainer 4.On the end face of the retainer body 3 that described and valve ball 1 close on, be formed with ring-type rectangle groove, in described ring-type rectangle groove, be provided with the seal ring 2 that is used to form valve ball 1 and retainer body 3 sealings, wherein seal ring 2 is pressed in ring-type rectangle groove by interference fit.And on the outer circumferential face of described retainer body 3 afterbodys and be also provided with O type circle 6 and fire prevention graphite packing 7 between valve body 8, guarantee that valve seat and valve body 8 normal temperature seal and the sealings under catching fire.
Assembly process of the present invention is: first, spring-leaf retainer 4 is rotated to the circular bead surface that approaches retainer body 3, then, seal ring 2, retainer body 3, spring-leaf retainer 4, cylindrical spring 5, O type circle 6 and fire prevention graphite packing 7 are packed into valve body 8 from the top of fixing ball valve, and put in the valve seat orifice of valve body 8, then spheroid 1 is packed into from the top of valve body 8, then torsional spring seat ring 4, make it away from the circular bead surface of retainer body 3, make seal ring 2 press close to spheroid 1.And dismounting is when of the present invention, order is the above-mentioned reverse order packing into.
The present invention is simple in structure, cost of production is low, by valve seat, is set to split-type structural, makes fixing ball valve can form dress formula, and then can realize the on-line maintenance of fixing ball valve, has reduced the parking off-time, has reduced economic loss.
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
