Abstract
The utility model discloses a PPR is by disk seat for stop valve, connect including water supply connector, water connectors and valve gap, the water supply connector is linked together with inhalant canal, water connectors and exhalant canal are linked together, the valve gap connects and is linked together with valve rod channel, the inhalant canal end is located the exhalant canal below, and forms a toper return water chamber that the top is mellow and full, internal screw thread metal connecting sleeve was taken in the embedding in the valve gap connected. The utility model discloses a disk seat adopts PPR material producing, makes the valve body have a rust -resistant function, can not pollute water, possess apparent economic benefits and social.
Description
Technical field
This utility model relates to water supply line valve, particularly relates to a kind of PPR for stop valve and ends valve seat.
Background technology
At present, the valve seat of water supply line stop valve is cast steel or cast iron manufacture, there is manufacturing cost and use cost
Height, the problem of the polluted water that easily gets rusty.And owing to seat of stop valve is changed by variations in temperature, the pressure of fluid media (medium), wash away, grinds
Damage, particulate matter accumulates extruding and corrodes and causes valve component spot corrosion, defect, impression and depression, and then generation faying face seals
The tightest interior leakage problem, becomes one of reason of affecting stop valve service life.
Utility model content
The purpose of this utility model is to provide a kind of PPR for stop valve to end valve seat.
In order to achieve the above object, the technical scheme that this utility model provides is: a kind of PPR stop valve for stop valve
Seat, including water supply connector, water out adapter and valve head connection, described water supply connector is connected with intake tunnel, described water out adapter
Being connected with exhalant canal, described valve head connection is connected with valve stem passage, and described intake tunnel end is positioned under exhalant canal
Side, and form the taper backwater cavity that a top is mellow and full, described valve head connection has been embedded in tapped metal adapter sleeve.
It is embedded with sealing ring below described metal adapter sleeve.
Described sealing ring is carbon seal ring.
Described water supply connector and water out adapter outer surface all offer anti-slip veins.
The beneficial effects of the utility model are: compared with traditional metal stop valve, this utility model is by PPR material system
Become, cheap for manufacturing cost, more easy-formation, also protect water quality and do not polluted by the corrosion of valve body.Valve head connection is embedded in threaded
Metal adapter sleeve threaded assembling with extraneous valve gap so that install, connect easier.It addition, backwater cavity in valve seat
Design slow down the liquid impact to valve base channel inwall, keeps stablizing of in-channel water stream, slow down current to valve rod and valve
The impact of lid, protects threaded valve gap to a certain extent, is allowed to not loosen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional structure schematic diagram of this utility model valve head connection.
Detailed description of the invention
Embodiment 1
A kind of PPR for stop valve ends valve seat, connects including water supply connector, water out adapter and valve gap
1, described water supply connector is connected with intake tunnel 2, and described water out adapter is connected with exhalant canal 3, described valve head connection 1
Being connected with valve stem passage 4, described intake tunnel 2 end is positioned at below exhalant canal 3, and forms the taper that a top is mellow and full
Backwater cavity 5, described valve head connection 1 has been embedded in tapped metal adapter sleeve 11.
It is embedded with sealing ring 12 below described metal connection 11 set.
Described sealing ring 12 is carbon seal ring.
Described water supply connector and water out adapter outer surface all offer anti-slip veins 6.
Valve seat of the present utility model uses PPR material to make, and coordinates extraneous valve gap, valve rod and handwheel etc. time actually used
Forming complete stop valve, wherein, the parts such as valve gap and valve rod can use rustless steel manufacture, the design of fitted seal circle 12, makes
Valve body has antirust function, will not polluted water, possess significant economic benefit and social benefit.Meanwhile, valve head connection 1 is embedded
Enter threaded metal adapter sleeve 11, is connected with extraneous valve gap be use threaded make to install, connection easier.Separately
Outward, in valve seat, the design of backwater cavity 5 slow down the liquid impact to valve base channel inwall, keeps stablizing of in-channel water stream, subtracts
Delay current to valve rod and the impact of valve gap, protected threaded valve gap to a certain extent, be allowed to not loosen.
