A kind of stop valve that can change valve seat online, it includes: valve body, be arranged in valve body by valve head, steel ball and valve rod group
The valve rod group component become, stem outer circumference is provided with filler seat, filler seat is provided with filler, filler is provided with gland,
Gland is installed on gland, connects fixing by stud and hex nut between gland and valve body；
Valve rod top is provided with valve stem nut by screw thread, and pedestal lower end is arranged on valve body by threaded engagement, and pedestal upper end leads to
Cross and be threadably mounted at valve stem nut periphery；Between described pedestal upper end and valve stem nut, limit screw is installed；
Valve rod upper end is provided with handwheel by hex nut, is provided with the first spring washer between hex nut and handwheel；
The bottom of described valve body is provided with screwed hole, and seal plug is arranged in the screwed hole of body base；
Described valve head lower thread is provided with valve seat plug.
Preferably, the above-described stop valve that can change valve seat online, install between described stud and hex nut
There is the second spring washer.
Preferably, the above-described stop valve that can change valve seat online, auxiliary is installed between seal plug and valve body
Sealing member.
Preferably, the above-described stop valve that can change valve seat online, it is provided with between described valve seat plug and valve body
Valve seat auxiliary sealing member.
The stop valve that can change valve seat online that this utility model provides, when sealing surface goes wrong, can back out seal plug,
Change auxiliary sealing member, or valve seat plug backed out, change valve seat auxiliary sealing member, change such that it is able to realize Fast-Maintenance,
Cost is greatly reduced.
Beneficial effect: compared to the prior art the stop valve that can change valve seat online that this utility model provides has the advantage that
The stop valve that can change valve seat online that this utility model provides, reasonable in design, good airproof performance, security performance is high,
It is easy to process, by valve seat plug and valve seat auxiliary sealing member, seal plug and auxiliary sealing member are screwed into valve body lower portion screw thread respectively
On, make valve body cavity airtight, keep in repair and change conveniently, cost can be greatly reduced.
