Abstract
The utility model relates to a novel wedge gate valve of removable disk seat device, including valve body, flashboard, disk seat, rectangular sealing washer, locking screw, valve rod, valve gap, valve -stem nut and hand wheel, the valve gap passes through threaded connection on valve body upper portion, inside the valve body was arranged in to the flashboard, the flashboard top was equipped with the T -slot, is connected with the valve rod head, the valve rod passes valve gap inside and is connected with valve -stem nut, valve -stem nut top and hand wheel connection, when the hand wheel rotated, valve -stem nut drove the valve rod and rotates, and the rotation of valve rod drives reciprocating of flashboard, realizes opening and closing of wedge gate valve, disk seat and valve body threaded connection are equipped with the rectangular sealing washer between disk seat and the valve body, the disk seat is connected the position with the valve body and is equipped with locking device. The device's advantage lies in: the disk seat separately is connected with the valve body, and cost of maintenance reduces, installing and removing and unloading simple, the convenience of spare part, sealed and locking safe and reliable for production and operator saving cost, eliminates the accident potential, has improved work efficiency and economic benefits.
Description
Technical field
This utility model belongs to field of petroleum machinery, relates to a kind of Wedge Gate Valves, particularly to the wedge of a kind of Novel replaceable valve seat
Formula gate valve.
Background technology
At present, in the actual production process of oil field, traditional Wedge Gate Valves, valve seat is integrated with valve body, and once sealing surface damages
Bad, need to change whole valve.So in maintenance process, add maintenance cost, increase the labor intensity of operating personnel,
It it is insoluble problem in maintenance process.Therefore a kind of wedge-type separated by valve body thus realize that valve seat is changed is invented with valve seat
Gate valve, in maintenance process, can be cost-effective, alleviate the labor intensity of operating personnel simultaneously, be to produce and use unit altogether
With the problem needing to solve.
Summary of the invention
This utility model is in order to solve the tradition technical problem that Wedge Gate Valves maintenance efficiency is low, cost is high, labor intensity is big, it is provided that
A kind of Wedge Gate Valves of Novel replaceable valve seat.
To achieve these goals, this utility model takes techniques below scheme to implement:
The Wedge Gate Valves of a kind of Novel replaceable valve seat, including valve body, flashboard, valve seat, valve rod, valve gap, valve stem nut and hands
Wheel, valve gap is threadedly attached in valve body top；Flashboard is placed in valve inner, and flashboard top is provided with T-slot, with valve rod head
Connect；Valve rod is connected through valve gap is internal with valve stem nut；Valve stem nut top is connected with handwheel；When hand wheel rotating, valve rod
Nut band ovable valve stem rotates, and rotating of valve rod drives the moving up and down of flashboard, it is achieved the opening and closing of Wedge Gate Valves；Valve seat with
Valve body screw thread connects, and is provided with square RunddichtringO between valve seat and valve body；Valve seat and valve body connecting portion are provided with locking device.
Preferably, locking device is that valve seat is provided with lock-screw with valve body connecting portion.
This utility model arranges removable valve seat, and valve seat is connected with valve body screw thread, is provided with square RunddichtringO between valve seat and valve body,
Ensureing to seal, valve seat and valve body connecting portion are provided with locking device, limit valve seat, prevent valve seat from loosening.The advantage of this device exists
In: valve seat is connected by screw thread and valve body, and dismounting is simple, safe and reliable, easy to maintenance, and then has saved cost, reduces
The labor intensity of staff, improves work efficiency and economic benefit.
Accompanying drawing explanation
Accompanying drawing 1 regards sectional structure schematic diagram for this utility model master；
Accompanying drawing 2 is I enlarged section structural representation in accompanying drawing 1.
In accompanying drawing 1,1, valve body, 2, valve seat, 3, square RunddichtringO, 4, lock-screw, 5, flashboard, 6, valve rod, 7,
Valve gap, 8, valve stem nut, 9, handwheel.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is further described.
As shown in Figure 1 and Figure 2, this utility model include valve body 1, valve seat 2, square RunddichtringO 3, lock-screw 4, flashboard 5,
Valve rod 6, valve gap 7, valve stem nut 8 and handwheel 9, valve gap 7 is threadedly attached in valve body 1 top；Flashboard 5 is placed in valve body
1 is internal, and flashboard 5 top is provided with T-slot, is connected with valve rod 6 head；Valve rod 6 is internal and valve stem nut 8 through valve gap 7
Connect；Valve stem nut 8 top is connected with handwheel 9；When handwheel 9 rotates, valve stem nut 8 band ovable valve stem 6 rotates, valve rod
6 rotate drives moving up and down of flashboard 5, thus realizes opening and closing of Wedge Gate Valves；Valve seat 2 is with valve body 1 screw thread even
Connect, between valve seat 2 and valve body 1, be provided with square RunddichtringO 3；Valve seat 2 and valve body 1 connecting portion are provided with locking device.Locking
Device is that valve seat is provided with lock-screw 4 with valve body connecting portion.
Fig. 2 show the embedded valve seat mechanism of several parts composition.Valve seat 2 by being threadably mounted in valve body 1, valve seat with
Valve body connecting portion is provided with seal groove, and square RunddichtringO 3 is arranged in the seal groove of valve inner, joins with valve seat 2 and valve body 1
Close, it is achieved seal.Valve seat and valve body connecting portion are provided with lock-screw 4, limit valve seat 2, prevent valve seat 2 from loosening.Need
During dismounting valve seat 2, unclamp lock-screw 4, rotary valve base 2, it is achieved thereby that change the purpose of valve seat.
This utility model advantage is: valve seat 2 is connected by screw thread and valve body 1, and dismounting is simple, safe and reliable, easy to maintenance,
And then saved cost, reduce the labor intensity of staff, improve work efficiency and economic benefit.
