Abstract
The utility model discloses dress formula fixing ball valve in one, belong to valve field.Concrete, on this dress formula fixing ball valve include valve body, bonnet, the spheroid being arranged in valve body, be arranged in valve body in move back formula valve component；Move back formula valve component in described and include valve seat support ring, the valve seat being arranged on valve seat support ring；It is provided with elastic compensation element between described valve seat support ring and valve body, and has pressure ring, pressure ring to be against on compensating element, in the connection of valve seat support ring excircle, and pressure ring surface configuration has latch blind hole.This utility model is used can effectively to adjust the pretightning force of valve component.
Description
Technical field
This utility model relates to valve field, is specifically related to dress formula fixing ball valve in one.
Background technology
Upper-mounting type ball valve is the one of ball valve, and upper-mounting type ball valve is widely used on oil and natural gas pipeline, and recover the oil,
In the devices such as oil refining, petrochemical industry, chemical industry, chemical fibre, metallurgy, electric power, nuclear power, food and papermaking.Upper-mounting type ball valve is dismantled on pipeline
Simple rapidly, easy to maintenance fast.When valve break down on pipeline need repair time, it is not necessary to from pipeline dismantle valve,
Need only dismantle middle flange bolt and nut, valve gap is taken off together with valve rod group component from valve body, then take out spheroid and
Valve seat combination part.Can repair spheroid and valve seat online, this maintenance saves the time, and the loss in producing is preferably minimized
Point.But this type of ball valve generally has the drawback that initial tension of spring can not adjust and control, and when assembling, amount of spring compression is big,
Assembling difficulty.
Utility model content
This utility model aims to provide dress formula fixing ball valve in one, to solve the problems referred to above.
For achieving the above object, the technical solution of the utility model is as follows:
Dress formula fixing ball valve in one, it is characterised in that: include valve body, bonnet, the spheroid being arranged in valve body, setting
Formula valve component is moved back in valve body；Move back formula valve component in described to include valve seat support ring, be arranged on valve seat support ring
Valve seat；It is provided with elastic compensation element between described valve seat support ring and valve body, and has in the connection of valve seat support ring excircle
Pressure ring, pressure ring is against on compensating element, and pressure ring surface configuration has latch blind hole.
Further, described compensating element, includes spring base, the counterbalance spring being connected in spring base, and counterbalance spring is against
On valve body.
Further, described in move back formula valve component be two, be separately positioned on spheroid both sides.
Further, described pressure ring is threadedly attached on valve seat support ring.
Further, described valve seat is the sealing ring being embedded in valve seat support ring end.
The beneficial effects of the utility model are: the yielding formula valve seat of upper-mounting type ball valve of the present utility model can install ball
Back out to provide enough installing spaces during body to both sides, from two side contacts and hold spheroid tightly after completing sphere installation, reach
Effect that is fixing and that seal.
Secondly, this utility model connects at valve seat support ring external screw thread pressure ring, uses fine thread rotation mode to carry out
The position of regulation support ring, pressure ring even circumferential distribution latch blind hole, only need to be the pin-and-hole above the insertion of ready straight pin
In, use impact type driving force rotating missile spring abutment screw-type pressure ring at circumferencial direction, drive support ring to move axially relative to pressure ring,
Thus realize the regulation of pretightning force, it is to avoid pretightning force excessive or excessively under, and regulative mode is simple and convenient.
Accompanying drawing explanation
Fig. 1 is the upper dress formula fixing ball valve structural representation that this utility model provides.
Fig. 2 is the close-up schematic view in Fig. 1 at I.
Labelling in figure: 1 be valve body, 2 be spheroid, 3 be bonnet, 4 be spring base, 5 be counterbalance spring, 6 be pressure ring, 7 be
Latch blind hole, 8 be valve seat support ring, 9 for sealing ring.
Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, dress formula fixing ball valve in one, it is characterised in that: include valve body 1, bonnet, 3, be arranged on
Spheroid 2 in valve body 1, be arranged in valve body 1 in move back formula valve component；Move back formula valve component in described and include valve seat support ring
8, the valve seat on valve seat support ring 8 it is arranged on；Elastic compensation element it is provided with between described valve seat support ring 8 and valve body 1, and
Valve seat support ring 8 excircle connects has pressure ring 6, pressure ring 6 to be against on compensating element, and pressure ring 6 surface configuration has latch blind hole 7.
The counterbalance spring 5 that described compensating element, includes spring base 4, is connected in spring base 4, counterbalance spring 5 is against on valve body 1.Described
Inside moving back formula valve component is two, is separately positioned on spheroid 2 both sides.Described pressure ring 6 is threadedly attached in valve seat support ring 8
On.Described valve seat is the sealing ring 9 being embedded in valve seat support ring 8 end.
In use, owing to this utility model has pressure ring 6 in the connection of valve seat support ring 8 external screw thread, so using closely-pitched spiral shell
Stricture of vagina rotation mode is adjusted the position of support ring.And pressure ring 6 even circumferential distribution latch blind hole 7, only need to be ready circle
In pin-and-hole above pin insertion, use impact type driving force rotating missile spring abutment 4 screw-type pressure ring 6 at circumferencial direction, drive and prop up
Hold the relative pressure ring 6 of circle to move axially, thus realize the regulation of pretightning force, it is to avoid pretightning force excessive or excessively under, and the side of regulation
Formula is simple and convenient.It should be noted that under valve working state left and right support ring should valve driving axis relatively symmetrical, i.e. left and right
Support ring pretightning force after installing is just suitable, more can guarantee that the sealing property that existing valve is good.
The yielding formula valve seat of upper-mounting type ball valve of the present utility model can be backed out to both sides when installing spheroid 2 to provide enough
Installing space, complete after spheroid 2 is installed from two side contacts and hold spheroid 2 tightly, reaching effect that is fixing and that seal.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
