Abstract
The utility model discloses a modified outer sliding sleeve type throttling valve. A valve seat (2) is arranged in a valve cavity of a valve body (1); a valve stem (4) is inserted in the valve body (1); and a bonnet (12) is arranged on the valve body (1) via a nut (11). The modified outer sliding sleeve type throttling valve is characterized in that an outer sliding sleeve body (3) is integrally formed on the bottom of the valve stem (1); stuffing box packing (5) is arranged at the upper end of the bonnet (12); a stuffing box gland (6) is in threaded connection to the inside of the bonnet (12); a positioning block (10) is arranged in a groove of the stuffing box gland (6); a bearing block (7) is in threaded connection with the bonnet (12); a crossover coupling (8) is connected to the bearing block (7) via a bearing (9); and the bearing (9), the crossover coupling (8), the positioning block (10), the stuffing box gland (6) and the stuffing box packing (5) are shielded by the bearing block (7). The using performance of the outer sliding sleeve type throttling valve can be realized; the structure of the outer sliding sleeve type throttling valve is simplified; the failure rate is reduced; repair procedures are reduced; and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of modified model exterior sliding bush type throttle valve.
Background technique
At present, easily there is outer sliding sleeve and stem dropping phenomenon in known exterior sliding bush type throttle valve, and stuffing box packing change need to remove valve gap, valve rod etc., operation is more loaded down with trivial details.
Summary of the invention
The purpose of this utility model is: a kind of modified model exterior sliding bush type throttle valve is provided, can realizes outer sliding sleeve throttle valve usability, also can simplified structure, and reduce rate of fault, reduce maintenance procedures, increase work efficiency.
Technical solution of the present utility model is: this throttle valve comprises valve body, valve seat, valve rod and valve gap, and valve seat is arranged in the valve pocket of valve body, and valve rod inserts to be installed in valve body, and valve gap is arranged on valve body through nut; It is characterized in that: the bottom integral forming outer sliding sleeve body of valve rod, stuffing box packing is arranged on the upper end of valve gap, Gland is threaded in valve gap, positioning block is arranged in the groove of Gland, the bearing support valve gap that is threaded, crossover sub is on bearing connection bearing seat, and bearing support gets up bearing, crossover sub, positioning block, Gland and stuffing box packing cover.
The utlity model has following advantage: 1, outer sliding sleeve body and valve rod are integrated integratedly, solve the outer sliding sleeve body problem that comes off; 2, stuffing box packing mounting point is moved on to valve gap upper end by valve gap lower end, solve the loaded down with trivial details problem of safeguarding; 3, Gland and valve gap, with being threaded togather, are fixed on stuffing box packing in valve bonnet seal region; 4, positioning block is arranged in Gland groove, and effect is mainly that valve rod allows outer sliding sleeve body and valve gap coaxial in rotation process, guarantees that outer sliding sleeve body moves up and down, and prevents from occurring scuffing between outer sliding sleeve body and Gland; 5, crossover sub rotatablely moves handwheel to convert outer sliding sleeve body to and move up and down; 6, bearing has been born the load that valve cavity pressure produces, and reduces the strength of valve switch, reduces switching torque; 7, bearing support gets up bearing, crossover sub, positioning block, Gland, stuffing box packing cover, prevent the frequent switch of throttle valve and cause Gland obscission occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 valve body, 2 valve seats, 3 outer sliding sleeve bodies, 4 valve rods, 5 stuffing box packing, 6 Glands, 7 bearing supports, 8 crossover subs, 9 bearings, 10 positioning blocks, 11 nuts, 12 valve gaps.
Embodiment
As shown in Figure 1, this throttle valve comprises valve body 1, valve seat 2, valve rod 4 and valve gap 12, and valve seat 2 is arranged in the valve pocket of valve body 1, and valve rod 4 inserts to be installed in valve body 1, and valve gap 12 is arranged on valve body 1 through nut 11; It is characterized in that: the bottom integral forming outer sliding sleeve body 3 of valve rod 1, stuffing box packing 5 is arranged on the upper end of valve gap 12, Gland 6 is threaded in valve gap 12, positioning block 10 is arranged in the groove of Gland 6, bearing support 7 valve gap 12 that is threaded, crossover sub 8 is in bearing 9 coupling shaft bearings 7, and bearing support 7 gets up bearing 9, crossover sub 8, positioning block 10, Gland 6 and stuffing box packing 5 covers.
