Abstract
The utility model relates to a bidirectional gate valve for slurry, which comprises a rigid valve body (5) provided with a flow channel (10) for being passed through by fluid. The inner side of the valve body (5) is provided with a U-shaped gate valve groove (11), in the groove, an elastic valve seat (6) is arranged, the upper part of the valve body (5) is provided with a filler chamber for placing sealing filler and a sealing gland (2). The utility model is characterized in that the sealing filler is composed of a sealing ring (3) whose section is O-shaped and a sealing ring (4) whose section is y-shaped which are combined. The utility model has advantages that the utility model can not only effectively avoid the leakage problem of upper sealing, but also solves the problem of tightly clamped gate which is caused by packing with lacked elasticity and too big friction force existing in prior art.
Description
The utility model relates to a kind of gate valve, particularly a kind of two-way slurries gate valve that is suitable in the use of two-way flow occasion.
Parallel Slide Valves is since the eighties begins to produce, uses in China, and with low cost with it, volume is little, and easy for installation receiving an acclaim is widely used in the industries such as metallurgy, electric power, chemical industry, mine.Up to the present, having designed and produced the Parallel Slide Valves of numerous species, is exactly wherein the most representative a kind of and adopt the gate valve of U type seal valve seat.Advantages such as this kind valve is simple in structure with it, sealability reliable, preparation process tube list account for tool always and leading position.But always being for many years, the last sealing of mentioned kind Parallel Slide Valves adopts that traditional sealing material--asbestos packing or pledget are as Sealing; because this type of sealing material lacks flexibility; sealability is relatively poor; leakage phenomenon appears in regular meeting after using a period of time; in addition, going back regular meeting in the use occurs because of the excessive phenomenon that flashboard is stuck of frictional force.
The purpose of this utility model provides a kind of structure more reasonable with regard to being to overcome above-mentioned deficiency of the prior art, and sealability is reliable, the two-way easily slurries gate valve of installation, maintenance.
The purpose of this utility model can adopt following measure to realize:
Two-way slurries gate valve of the present utility model comprises the rigidity valve body that is provided with the runner that passes through for fluid, be provided with in the valve body inboard one and the U type of runner concentric explain the plate groove, in this groove elastic seat is housed, is provided with filler chamber and the sealing gland of laying stuffing box packing on the top of valve body; Its stuffing box packing is to be that the seal ring of O type and seal ring that section is the y type combine by section.
Furtherly, the y RunddichtringO is positioned at the bottom of filler chamber, and its opening surface is downward, and featheredge is near flashboard; The O RunddichtringO be placed on the y RunddichtringO above; Y RunddichtringO and O RunddichtringO preferably adopt elasticity preferably tartan be made.
But in order to guarantee flashboard smooth running when doing upper and lower opening movement, influence sealability and be unlikely to swing in the flashboard chamber, the two ends up and down in the flashboard chamber of the utility model above valve flowing channel are provided with the upper and lower seam that play the guiding role.
The y RunddichtringO that the utility model adopted has the function of sealing voluntarily under the pressure voluntarily of medium, the favorable elasticity that self possessed of O RunddichtringO in addition, this just makes the utility model not only can stop the leakage problem of sealing effectively, and can solve because of prior art exist because of packing lacks flexibility, the excessive stuck problem of flashboard that causes of frictional force.In addition, but being provided with of the upper and lower seam in flashboard chamber guarantees flashboard smooth running when doing upper and lower opening movement, avoided making the deficiency of sealability decline because of flashboard swings in the flashboard chamber.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a main sectional view of the present utility model, has saved the operation opening device that is installed in valve body top among the figure.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the partial enlarged drawing of upper gland packing chamber among Fig. 1.
The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):
From above accompanying drawing as can be seen, two-way slurries gate valve of the present utility model comprises the rigidity valve body (5) that is provided with the runner (10) that passes through for fluid, be provided with one and the U type flashboard groove (11) of runner (10) concentric in valve body (5) inboard, elastic seat (6) is housed in this groove, top at valve body (5) is provided with the filler chamber of laying stuffing box packing, by section be the seal ring (3) of O type and seal ring (4) that section is the y type be combined into and combination seal be placed in the filler chamber, combination seal is fitted in by sealing gland (2) and constitutes the sealing of going up of explaining plate (1) in the filler chamber.
Y RunddichtringO (4) in the combination seal is positioned at the bottom of filler chamber, and its opening surface is downward, and featheredge is near flashboard; O RunddichtringO (3) be placed on the y RunddichtringO above; Y RunddichtringO and O RunddichtringO preferably adopt elasticity preferably tartan be made.
But in order to guarantee flashboard smooth running when doing upper and lower opening movement, influence sealability and be unlikely to swing in the flashboard chamber, the two ends up and down in the flashboard chamber (8) of the utility model above valve flowing channel are provided with the upper and lower seam (9) (7) that play the guiding role.
Claims (4)
1, a kind of two-way slurries gate valve, comprise the rigidity valve body (5) that is provided with the runner (10) that passes through for fluid, be provided with one and the U type flashboard groove (11) of runner (10) concentric in valve body (5) inboard, elastic seat (6) is housed in this groove, be provided with filler chamber and the sealing gland (2) of laying stuffing box packing on the top of valve body (5), it is characterized in that: stuffing box packing is to be that the seal ring (3) of O type and seal ring (4) that section is the y type combine by section.
2, two-way slurries gate valve according to claim 1, it is characterized in that: y RunddichtringO (4) is positioned at the bottom of filler chamber, and its opening surface is downward, and featheredge is near flashboard; O type sealed picture (3) be placed on the y RunddichtringO above.
