Abstract
Move back formula top dress fixing ball valve in the utility model discloses a kind of valve seat, belong to valve field.Concrete, move back in this valve seat formula top dress 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；Described valve seat support ring is externally connected with draw-ring type spring base, and spring base excircle is provided with chain mounting groove, and spring base end face is provided with the lug with pin-and-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, moves back formula top dress fixing ball valve in being specifically related to a kind of valve seat.
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 moves back formula top dress fixing ball valve in aiming to provide a kind of valve seat, to solve the problems referred to above.
For achieving the above object, the technical solution of the utility model is as follows:
Formula top dress fixing ball valve is moved back in a kind of valve seat, it is characterised in that: include valve body, bonnet, be arranged in valve body
Spheroid, be arranged in valve body in move back formula valve component；Move back formula valve component in described to include valve seat support ring, be arranged on valve seat
Valve seat on support ring；Described valve seat support ring is externally connected with draw-ring type spring base, and spring base excircle is provided with chain
Mounting groove, spring base end face is provided with the lug with pin-and-hole.
Further, being provided with counterbalance spring in described spring base, counterbalance spring is against on valve seat support ring.
Further, described in move back formula valve component be two, be separately positioned on spheroid both sides.
Further, described valve seat is the sealing ring being embedded in valve seat support ring end.
Further, it is provided with multisection type chain in described chain mounting groove.
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 is provided with the lug of band pin-and-hole on spring base, and in use, available latching connects specially
Frock, make left and right valve seat be close on sphere completely, and chain be installed.And when needing repairing, utilize frock to take out chain
After, support ring pusher, spheroid standard-sized sheet ball mouth is vertically completely exposed, i.e. can be taken off spheroid, simple to operate, pretightning force is adjustable.
Accompanying drawing explanation
Fig. 1 be this utility model provide valve seat in move back formula top dress fixing ball valve structural representation.
Fig. 2 is the close-up schematic view in Fig. 1 at I.
Fig. 3 is the valve seat construction schematic diagram that this utility model provides.
Labelling in figure: 1 be valve body, 2 for spheroid, 3 for bonnet, 4 for spring base, 5 for valve seat support ring, 6 for chain, 7
For counterbalance spring, 8 be sealing ring, 9 be lug, 10 for chain mounting groove.
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, Figure 2, Figure 3 shows, move back formula top dress fixing ball valve in a kind of valve seat, it is characterised in that: include valve body 1, on
Valve gap 3, the spheroid 2 being arranged in valve body 1, be arranged in valve body 1 in move back formula valve component；Formula valve component bag is moved back in described
Include valve seat support ring 5, the valve seat being arranged on valve seat support ring 5；Described valve seat support ring 5 is externally connected with draw-ring type spring base 4,
And spring base 4 excircle is provided with chain mounting groove 10, spring base 4 end face is provided with the lug 9 with pin-and-hole.
Being provided with counterbalance spring 7 in described spring base 4, counterbalance spring 7 is against on valve seat support ring 5.Formula valve is moved back in described
Holder assembly is two, is separately positioned on spheroid 2 both sides.Described valve seat is the sealing ring 8 being embedded in valve seat support ring 5 end.Institute
Multisection type chain 6 it is provided with in stating chain mounting groove 10.
When mounted, successively spring base 4, counterbalance spring 7, valve seat support ring 5, spheroid 2 are installed in valve body 1.Hereafter,
Special tooling joint can be utilized to be connected on spring base 4 ground lug 9 through latching, front and back synchronize dextrorotation adjusting screw rod, until left
Right valve seat is close on sphere completely, it was observed that the chain mounting groove 10 above spring base 4 cylindrical has been completely exposed the chain on valve body 1
Bar 6 bearing-surface, can pull out as required in this state or load chain 6.Finally install valve gap 3 again and valve rod is
Can.
And when needing repairing, left and right chain 6 now should be pulled out.After mounting tool, front and back synchronize left-handed adjusting screw rod, suitable
Taking off frock, the most half-open spheroid 2 after strutting, from top, copper rod class material taps support ring front/rear end gently,
Support ring is pushed in valve seat orifice, until spheroid 2 standard-sized sheet ball mouth is vertically completely exposed
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.
