Abstract
The utility model relates to a kind of head valve of can high pressure changing airtight and watertight padding.Mainly solve that existing head valve need to be closed pipe network when changing airtight and watertight padding and to the problem of field produces inconvenience.It is characterized in that: described valve gland (6) lower inside has counterbore, counterbore inside has been threaded connection sealing block (9), described leading screw (10) bottom is provided with the boss matching with sealing block (9), and is provided with sealing ring between sealing block (9) and leading screw (10).This head valve can replace with pressure airtight and watertight padding, does not need to close pipe network, to field produces, can not impact.
Description
Technical field
The utility model relates to field, a kind of oil field, specifically a kind of head valve of can high pressure changing airtight and watertight padding.
Background technology
Oil field shaft mouth valve has a variety of, and the most frequently used is 250 valves, and the airtight and watertight padding after long time running of this valve is worn, and for guaranteeing sealing, needs to change filler.But current head valve, when changing airtight and watertight padding, need to stop producing, closing pipe network, to field produces, makes troubles, and affects output, reduces production efficiency.
Summary of the invention
In order to overcome that existing head valve need to be closed pipe network when changing airtight and watertight padding and to the deficiency of field produces inconvenience, the utility model provides a kind of head valve of can high pressure changing airtight and watertight padding, this head valve can replace with pressure airtight and watertight padding, do not need to close pipe network, to field produces, can not impact.
The technical solution of the utility model is: a kind of head valve of can high pressure changing airtight and watertight padding, comprise valve gland, leading screw, described valve gland internal whorl is connected with filler briquetting, between described filler briquetting and leading screw, be equipped with airtight and watertight padding, described valve gland lower inside has counterbore, counterbore inside has been threaded connection sealing block, and described leading screw bottom is provided with the boss matching with sealing block, and is provided with sealing ring between sealing block and leading screw.
Between described filler briquetting lower plane and valve gland, be provided with airtight and watertight padding.
The utlity model has following beneficial effect: owing to taking such scheme, valve gland lower inside has counterbore, in counterbore, be provided with sealing block, when the wearing and tearing of the airtight and watertight padding between filler briquetting and leading screw need to be changed like this, do not need leading screw to take out, only need be by the bearing gland on top, after bearing and copper sheathing take off, just filler briquetting can be taken out, change airtight and watertight padding, now, between the sealing block of bottom and leading screw and valve gland, same maintenance, seals, realization needn't be closed pipe network just can under high pressure change the object of airtight and watertight padding, can not impact producing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-handwheel pressure cap in figure, 2-handwheel, 3-bearing gland, 4-copper sheathing, 5-bearing, 6-valve gland, 7-filler briquetting, 8-airtight and watertight padding, 9-sealing block, 10-leading screw.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of head valve of can high pressure changing airtight and watertight padding, comprise valve gland 6, leading screw 10, described valve gland 6 internal whorls are connected with filler briquetting 7, between described filler briquetting 7 and leading screw 10, be equipped with airtight and watertight padding 8, between filler briquetting 7 lower planes and valve gland 6, be provided with equally airtight and watertight padding.Leading screw 10 external screw-threads connect copper sheathing 4, between copper sheathing 4 and valve gland 6, be provided with bearing 5, bearing 5 tops are provided with bearing gland 3, and are threaded connection between bearing gland 3 and valve gland 6, copper sheathing 4 external stabilities have handwheel 2, and copper sheathing 4 tops are connected with handwheel pressure cap 1.Described valve gland 6 lower inside have counterbore, counterbore inside has been threaded connection sealing block 9, on sealing block 9, between plane and the plane of counterbore, be equipped with sealing ring, described leading screw 10 bottoms are provided with the boss matching with sealing block 9, and between sealing block 9 inside and leading screw 10, be provided with sealing ring, two above-mentioned place's sealing rings can guarantee sealing between sealing block 9 and leading screw 10 and valve gland 6.
When needs are changed airtight and watertight padding 8, do not need to close pipe network, only need swivel bearing gland 3, after handwheel 2, copper sheathing 4 and bearing 5 are taken out successively, by special tool, filler briquetting 7 is taken out, with regard to replaceable airtight and watertight padding 8.And now, between the sealing block 9 of bottom and leading screw 10 and valve gland 6, still keep sealing.After airtight and watertight padding 8 is changed, then filler briquetting 7 is installed.This valve also can be applicable to two cun of above slide valve or stop valves, has wide range of applications.
