Abstract
The utility model relates to a large-caliber top-mounted fixed ball valve, which comprises a valve ball, a valve seat and a valve body, and the valve seat is arranged between the valve ball and the valve body. The large-caliber top-mounted fixed ball valve is characterized in that: the valve seat consists of two parts, i.e. a holder body and a spring retainer, and is of a split structure, the periphery of the holder body is provided with a shoulder, an external thread is machined on the periphery of the tail of the shoulder, an internal thread is machined in the spring retainer, and the holder body is screwed down in the spring retainer. The structure of the large-caliber top-mounted fixed ball valve is simple, and the production cost is low; since the valve seat is arranged as the split structure, the fixed ball valve can be top-mounted, and thereby can be maintained on line, consequently, the shutdown time is shortened, and the economic loss is reduced.
Description
Technical field
The utility model relates to a kind of valve seat of upper dress formula fixing ball valve, especially relates to a kind of valve seat that is applied to dress formula fixing ball valve on the heavy caliber, belongs to the valve design technical field.
Background technique
We know, the characteristics of the full diversion Design of fixing ball valve, and it is little, easy to operate to have a resistance of medium, and the advantage such as quick is widely used on the 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, and especially weldering connects valve, in order to keep in repair valve, have to valve is cut down from pipeline, cause the relevant tube line length time to be stopped and stop production, cause heavy economic losses.
The model utility content
Be to solve the deficiencies in the prior art, the purpose of this utility model be to provide a kind of can on-line maintenance, reduce dress formula fixing ball valve on the heavy caliber of parking economic loss.
For achieving the above object, the utility model is to realize by following technological scheme:
Dress formula fixing ball valve on the heavy caliber, comprise valve ball, valve seat and valve body, described valve seat is arranged between described valve ball and the valve body, it is characterized in that, described valve seat comprises retainer body and spring-leaf retainer two-part, be split-type structural, be provided with shoulder on the excircle of described retainer body, be processed with outside thread on the excircle of the afterbody of described shoulder, and the inside of described spring-leaf retainer is processed with internal thread, and described retainer body is connected screw-thread fit with spring-leaf retainer and is screwed connection.
Further, the end face of the spring-leaf retainer that described and valve body closes on caves inward and is formed with rectangle assembling groove, be provided with cylindrical spring in the described rectangle assembling groove, and the two ends of described cylindrical spring contacts with valve body with spring-leaf retainer respectively.
And be formed with the ring-type rectangle groove on the end face of described and the retainer body that valve ball closes on, be provided with the seal ring that is used to form valve ball and retainer body sealing in the described ring-type rectangle groove.
And also be provided with O type circle and fire prevention graphite packing on the outer circumferential face of described retainer body afterbody and between the valve body.
The beneficial effects of the utility model are: the utility model is simple in structure, cost of production is low, be set to split-type structural by valve seat, so that fixing ball valve can form the dress formula, and then can realize the on-line maintenance of fixing ball valve, reduce the parking off-time, reduced economic loss.
Description of drawings
Fig. 1 is the utility model one embodiment's structural representation.
The main mark implication is as follows among the figure:
1, valve ball 2, seal ring 3, retainer body 4, spring-leaf retainer

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Fig. 1 is the utility model one embodiment's structural representation.
As shown in Figure 1: dress formula fixing ball valve on the heavy caliber, comprise valve ball 1, valve seat and valve body 8, described valve seat is arranged between described valve ball 1 and the valve body 8, described valve seat comprises retainer body 3 and spring-leaf retainer 4 two-part, be split-type structural, be provided with shoulder on the excircle of described retainer body 3, be processed with outside thread on the excircle of the afterbody of described shoulder, and the inside of described spring-leaf retainer 4 is processed with internal thread, and described retainer body 3 is connected with spring-leaf retainer and is screwed connection by screw-thread fit.
Wherein, the end face of the spring-leaf retainer 4 that described and valve body 8 closes on caves inward and is formed with rectangle assembling groove, be provided with cylindrical spring 5 in the described rectangle assembling groove, and the two ends of described cylindrical spring 5 contacts with valve body 8 with spring-leaf retainer 4 respectively.Then be formed with the ring-type rectangle groove on the end face of the retainer body 3 that described and valve ball 1 closes on, be provided with the seal ring 2 that is used to form valve ball 1 and retainer body 3 sealings in the described ring-type rectangle groove, wherein seal ring 2 is pressed in the ring-type rectangle groove by interference fit.And also be provided with O type circle 6 and fire prevention graphite packing 7 on the outer circumferential face of described retainer body 3 afterbodys and between the valve body 8, guarantee the sealing of valve seat and valve body 8 normal temperature and the sealing under catching fire.
Assembly process of the present utility model is: at first, spring-leaf retainer 4 is rotated to the circular bead surface near retainer body 3, then, with seal ring 2, retainer body 3, spring-leaf retainer 4, cylindrical spring 5, O type circle 6 and fire prevention graphite packing 7 from valve body 8 is packed at the top of fixing ball valve into, 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 the 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 during the utility model, and then order is the above-mentioned reverse order of packing into.
The utility model is simple in structure, cost of production is low, is set to split-type structural by valve seat, so that fixing ball valve can form the 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 utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
