Abstract
The utility model is related to a kind of upper-mounting type ball valve, including valve body (1) and valve seat (2), wherein described valve seat (2) outside, right-hand member are provided with external screw thread (3), the external screw thread (3) is corresponding with locking nut (4), the valve seat (2) is arranged on valve body (1), and the locking nut (4) can drive valve seat (2) to be moved to the left.The utility model disclosure satisfy that the use requirement of valve through overtesting and checking, and rational in infrastructure, the convenient and dismounting and maintenance of valve in use, reduces use cost, at the same time also solves this problem for dismounting maintenance in the duct.
Description
Technical field
The utility model belongs to ball valve technical field, more particularly to a kind of upper-mounting type ball valve.
Background technology
The closure member spheroid of existing upper-mounting type ball valve is installed from valve body middle chamber, because the spring at the two valve seat back sides is due to multiple
Position, in the case of spring elemental height, two valve base chambers distance is less than the mounting distance of spheroid, is accomplished by when installing spheroid by outer
Spring-compressed is made the distance of two valve base chambers be more than the mounting distance of spheroid, is that this opens a technique on the inside of valve seat runner by power
Groove (as shown in Figure 3 and Figure 4), makes two valve seats to two ends movement come real with special tooling at valve body two ends with nut when installing spheroid
Existing, this structure is complex, and cost is higher and is only applicable to the assembling of single valve, is not suitable for dismounting in the duct
Safeguard.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of upper-mounting type ball valve, by setting outer spiral shell in valve body both sides
Line, when solving existing upper-mounting type ball valve installation spheroid, structure is complex, and cost is higher and is only applicable to the dress of single valve
Match somebody with somebody, the problem of dismounting not being suitable in the duct is safeguarded.
The utility model solves the technical scheme that its technical problem used：A kind of upper-mounting type ball valve, including valve are provided
Body and valve seat, wherein valve seat outside, right-hand member are provided with external screw thread, the external screw thread is corresponding with locking nut, the valve seat
On valve body, the locking nut can drive valve seat to be moved to the left.
Further technical scheme of the present utility model is provided between the valve seat and valve body, with locking nut corresponding position
Spring.
Further technical scheme of the present utility model is, stepped for three on the outside of the valve seat.
Further technical scheme of the present utility model is that the second ladder of the valve seat is provided with two grooves.
Further technical scheme of the present utility model is that the external screw thread on the valve seat is arranged on the 3rd ladder.
Further technical scheme of the present utility model is that when the locking nut is simultaneously tight, valve seat is moved to the left.
Further technical scheme of the present utility model is, when the locking nut unclamps, valve seat under the action of the spring to
Move to right dynamic sealing.
Beneficial effect
The utility model disclosure satisfy that the use requirement of valve through overtesting and checking, and rational in infrastructure, convenient and valve
Dismounting and maintenance in use, reduce use cost, at the same time also solve this that dismount maintenance in the duct
Problem.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment 1
As depicted in figs. 1 and 2, a kind of upper-mounting type ball valve, including valve body 1 and valve seat 2, wherein the outside of the valve seat 2, right-hand member
Provided with external screw thread 3, the external screw thread 3 is corresponding with locking nut 4, and the valve seat 2 is arranged on valve body 1, the locking nut 4
Valve seat 2 can be driven to be moved to the left, spring 5 is provided between the valve seat 2 and valve body 1, with the corresponding position of locking nut 4.
As shown in Fig. 2 the outside of valve seat 2 is stepped for three, the second ladder of the valve seat 2 is provided with two grooves 6,
External screw thread 3 on the valve seat 2 is arranged on the 3rd ladder.
When the locking nut 4 is simultaneously tight, valve seat 2 is moved to the left；When the locking nut 4 unclamps, valve seat 2 is in spring effect
Under move right sealing.
The utility model by valve seat Excircle machining into screw thread (as shown in Figure 2), during installation, with locking nut by itself and it is tight,
Valve seat will be moved to direction end direction before, and the mounting distance for meeting spheroid is realized with this, locking nut is unclamped afterwards,
Valve seat realizes sealing according to spring reset, even if after valve is arranged on pipeline, arbitrarily can also carry out spheroid and accessory
Dismounting, the convenient and dismounting and maintenance of valve in use reduces use cost.
