Abstract
The utility model provides a gate valve which can be quickly connected with a pipeline. The quickly-mountable gate valve for the pipeline comprises a valve body having a water inlet and a water outlet at the two ends, a valve cover which is hermetically connected with the valve body, a valve rod connected with the valve cover by screw threads and a flashboard connected to the lower end of the valve rod and positioned in a valve chamber of the valve body; the inner holes of the water inlet and the water outlet are both conical holes; sealing rings are arranged in the conical holes; the outer circumferences of the water inlet and the water outlet are connected with a screw cap by screw threads; a fastening ring is arranged on the inner bottom surface of the screw cap; the fastening ring and the sealing rings have contact with each other in axial direction; when the screw cap is rotated, the screw cap pushes the sealing rings to move along the axial direction by the fastening ring., so that the sealing rings are tightly pressed on the outer circumferential surface of a water inlet tube extending into the water inlet or a water outlet tube extending into the water outlet, thereby forming sealed contact.
Description
Technical field
The utility model relates to a kind of gate valve.
Background technique
Existing gate valve, the water intake at its valve body two ends generally links to each other with pipeline through flange with water outlet.This linkage structure connects inconvenient.
Summary of the invention
The purpose of the utility model provides a kind of gate valve that can link to each other with pipeline fast.
This pipeline quick mounting gate valve; Comprise that two ends have the valve body of water intake and water outlet; The valve gap that links to each other with valve seal with the valve rod of valve gap through being threaded, is connected the flashboard of the valve pocket valve rod lower end, that be positioned at valve body; The endoporus of water intake and water outlet is cone shape hole, and seal ring is arranged in the cone shape hole; The periphery of water intake and water outlet is through the nut that has been threaded; The inner bottom surface place of nut is provided with collar, and collar is axially contacting with seal ring; During rotating screw cap, nut promotes seal ring through collar and moves vertically, thereby makes seal ring be pressed on to stretch into the intake pipe of water intake or stretch on the outer circumferential face of outlet pipe of water intake, forms the sealing contact.
The beneficial effect of the utility model: through rotating screw cap; Promoting seal ring moves vertically; Because seal ring is provided with in the endoporus of water intake and water outlet of taper; So tighten in the seal ring break-in, thereby make seal ring be pressed on intake pipe or stretch on the outer circumferential face of outlet pipe of water intake, formation is tightly connected.Therefore this gate valve is connected fast with pipeline, and sealing is reliable.
Above-mentioned pipeline quick mounting gate valve, the inner bottom surface of nut and collar outer circumferential face all are corresponding tapers.
Above-mentioned pipeline quick mounting gate valve, the bottom of valve pocket is not less than the bottom of water intake and water outlet.Like this, valve body bottom has been avoided accumulating the slag thing and the secondary pollution that causes water quality, and it is impaired and cause leakage phenomenon that flow velocity accelerates to wash away the unlikely flashboard that causes of foreign material when closing flashboard simultaneously.
Above-mentioned pipeline quick mounting gate valve, the valve pocket internal surface is coated with health level epoxy resin layer.Effective like this pollution that prevents the corrosion of iron pressure part to medium, the friction between medium and the valve is reduced on simultaneously lubricious surface, reduces the flow resistance of medium effectively.
Above-mentioned pipeline quick mounting gate valve, flashboard adopt the outer whole sulfuration bag EPDM rubber of copper core.Like this, not perishable rust of flashboard and sealing effect are better.
Description of drawings
Fig. 1 is the schematic representation of the utility model.
Embodiment
Referring to shown in Figure 1, connect through screw 7 between valve gap 10 and the valve body 1; Connect through trapezoidal thread between flashboard 6 and the valve rod 9; When handwheel 13 rotations, drive valve rod 9 and rotate, valve rod 9 drives flashboard 6 through trapezoidal thread and moves up and down, thereby realizes the open and close of gate valve.
Between valve gap 10 and the valve body 1, between valve gap 10 and the joint 12 through rubber washer 8 sealings; Seal through three road O type circles 11 between valve rod and the joint.
Valve body 1, valve gap 10 inside and outside spray health level epoxy resin powders effectively prevent the pollution of the corrosion of iron pressure part to medium, and the friction between medium and the valve is reduced on simultaneously lubricious surface, reduces the flow resistance of medium effectively.Flashboard 6 adopts the outer whole sulfuration bag EPDM rubber of copper core, and not perishable rust and sealing effect are better.
Adopt and the pipe identical flat design in the end valve body 1 bottom, avoids accumulating the slag thing and the secondary pollution that causes water quality, and it is impaired and cause leakage phenomenon that the flow velocity quickening washes away the unlikely flashboard that causes of foreign material when closing flashboard 6 simultaneously.
During pipe laying, directly pipe 3 is inserted valve body 1 inside through collar 4, seal ring 5, nut 2 is screwed to get final product.Drive collar 4 when nut 2 is screwed with seal ring 5 compressions, guarantee the sealing between seal ring 5 and the pipe 3, prevent that medium from leaking outside.
Claims (5)
1. pipeline quick mounting gate valve; Comprise that two ends have the valve body of water intake and water outlet; The valve gap that links to each other with valve seal with the valve rod of valve gap through being threaded, is connected the flashboard of the valve pocket valve rod lower end, that be positioned at valve body; It is characterized in that: the endoporus of water intake and water outlet is cone shape hole, and seal ring is arranged in the cone shape hole; The periphery of water intake and water outlet is through the nut that has been threaded; The inner bottom surface place of nut is provided with collar, and collar is axially contacting with seal ring; During rotating screw cap, nut promotes seal ring through collar and moves vertically, thereby makes seal ring be pressed on to stretch into the intake pipe of water intake or stretch on the outer circumferential face of outlet pipe of water intake, forms the sealing contact.
2. pipeline quick mounting gate valve as claimed in claim 1 is characterized in that: the inner bottom surface of nut and collar outer circumferential face all are corresponding tapers.
3. pipeline quick mounting gate valve as claimed in claim 1, it is characterized in that: the bottom of valve pocket is not less than the bottom of water intake and water outlet.
4. pipeline quick mounting gate valve as claimed in claim 1 is characterized in that: the valve pocket internal surface is coated with health level epoxy resin layer.
5. pipeline quick mounting gate valve as claimed in claim 1 is characterized in that: flashboard adopts the outer whole sulfuration bag EPDM rubber of copper core.
