Description

A kind of well head inside screw nonrising stem type gate valve
Technical field
The utility model relates to head valve technical field more particularly to a kind of well head inside screw nonrising stem type gate valves.
Background technique
At present in the operation of exploitation petroleum, when thering is the oil-water well of pressure to need construction operation at well head, the dark lever brake of well head Valve is marine and the drilling of land petroleum and natural gas and production system important component, is played in the sealing of wellhead assembly to pass Important role, existing well head inside screw nonrising stem type gate valve is in use, poor sealing performance, and opening and closing is cumbersome, and using effect is poor, and it is raw to influence oil field It produces.
Utility model content
Goal of the invention: well head inside screw nonrising stem type gate valve leakproofness to be solved in the utility model is poor, opens and closes cumbersome and using effect The technical problem of difference, the utility model provide a kind of well head inside screw nonrising stem type gate valve.
4, technical solution: a kind of well head inside screw nonrising stem type gate valve, comprising: valve body, valve deck, valve seat, waveform spring, flashboard, is led at screw Plate, valve rod, valve stem nut, handwheel, rolling bearing, bearing mounting base, valve rod base, feeding port pass through spiral shell on the upside of the valve body Nail is connected with valve deck, and the inside of the valve body is equipped with valve seat, is equipped with waveform spring between the valve body and valve seat, on the valve seat Flashboard is slidably connected, guide plate is installed on the valve seat on the downside of the flashboard, valve rod, the valve are connected on the upside of the flashboard The upper end of bar is connected by valve stem nut with handwheel, and rolling bearing is equipped on the valve stem nut, the rolling bearing Outside is connected with bearing mounting base, and valve rod base is equipped on the valve rod on the upside of the valve deck, and the valve rod base is equipped with feeding port.
Preferably, it is connected between the valve rod and flashboard by trapezoidal thread.
Preferably, pin is connected between the valve rod and valve stem nut.
The utility model has the beneficial effects that a kind of well head inside screw nonrising stem type gate valve is compact-sized, easy to operate, design cost is low, work It is fast to make speed, good airproof performance is opened flexibly, and using effect is good.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of well head inside screw nonrising stem type gate valve of the utility model.
Specific embodiment
The utility model is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this For the common process personnel of technology field, without departing from the principle of this utility model, to the various of the utility model The modification of equivalent form falls within the application range as defined in the appended claims.
Embodiment
As shown in Figure 1, a kind of well head inside screw nonrising stem type gate valve, comprising: valve body 1, screw 2, valve deck 3, valve seat 4, waveform spring 5, lock Plate 6, guide plate 7, valve rod 8, valve stem nut 9, handwheel 10, rolling bearing 11, bearing mounting base 12, valve rod base 13, feeding port 14, institute State the upside of valve body 1 and valve deck 3 be connected with by screw 2, the inside of the valve body 1 is equipped with valve seat 4, the valve body 1 and valve seat 4 it Between be equipped with waveform spring 5, flashboard 6 is slidably connected on the valve seat 4, guide plate 7 is installed on the valve seat 4 of 6 downside of flashboard, The upside of the flashboard 6 is connected with valve rod 8, and the upper end of the valve rod 8 is connected by valve stem nut 9 with handwheel 10, the valve Rolling bearing 11 is installed, the outside of the rolling bearing 11 is connected with bearing mounting base 12, on the valve deck 3 on stem nut 9 Valve rod base 13 is installed, the valve rod base 13 is equipped with feeding port 14 on the valve rod 8 of side.
Preferably, it is connected between the valve rod 8 and flashboard 5 by trapezoidal thread 15.
Preferably, pin 16 is connected between the valve rod 8 and valve stem nut 9.
The utility model has the beneficial effects that a kind of well head inside screw nonrising stem type gate valve, handwheel 10 is rotated with ovable valve stem 8, by valve rod 8 with Trapezoidal thread 15 between flashboard 6 realizes the up and down motion of flashboard 6, to operate the on and off of valve.When valve wide open state, into Outlet pressure is equal, and the waveform spring 5 between valve seat and valve body can make 4 self-aligning of flashboard 6 and valve seat.When valve full off state, Flashboard 6 is pressed under the collective effect of valve seat 4 and spring thrust, and reaches necessary seal pressure, realization is sealed in valve seat and valve One flexible compensation performance high waveform spring 5 is set between body, valve seat 4 can be made to realize axial floating, and be able to achieve diameter To floating, guarantee that valve seat 4 does not block when work, and make valve seat 4 with pretightning force, to make between valve seat 4 and flashboard 5 in low pressure Good sealing performance can also be kept when power.Equipped with the guide plate 7 that can accommodate flashboard 6 on valve seat 6,6 skew of flashboard is eliminated A possibility that.Load when bearing absorbs the opening and closing of flashboard 6 is installed, thus the torque that handwheel will be operated on valve stem nut 9 It minimizes.
