Introduction PVC tee
PVC tee is also called pvc fitting tee or tee pvc pipe fitting. pvc Tee joint is used at the branch pipe of main pipe. It has three openings, that is, one import and two exports, or two imports and one export.
PVC tee is a kind of PVC chemical pipe fitting, which is used to change the direction of fluid. There are T-shaped and Y-shaped pipes, equal diameter pipe orifices and reducing orifices. It can be used for water transmission pipeline, oil transmission pipeline and various liquid chemical material transmission pipelines. It is mainly used in medicine, water conservancy (water-saving irrigation, water supply and drainage), energy (oil, natural gas, nuclear industry), construction and other engineering fields.
Tee can be divided into metal material and non-metal material according to material. The metal tees are carbon steel, stainless steel, alloy steel, etc., and the screw tees; the non-metal tees are PVC, UPVC, CPVC,IPS,PPR,PP etc. According to the connection mode, it can be divided into two types: snap type and threaded connection. According to the shape, it can be divided into T type and herringbone type.
Tee is classified according to pipe diameter:
1. Tee with the same diameter: tee with the same diameter of main pipe and branch pipe
2. Reducing tee: tee with branch pipe diameter smaller than main pipe diameter
The tee is classified according to the docking form:
1. Butt welded tee: refers to the tee pipe fittings welded after butt joint with the connecting pipe fittings.
2. Socket tee: it is a tee pipe that is welded or welded after the connecting pipe is inserted into each end of the tee.
3. Ferrule tee: it is a tee fitting with ferrule connector at each end, which is inserted and then tightened.
4. Threaded tee: a tee fitting that is threaded to a fitting.
Tee is classified by material and branch type:
It can be divided into stainless steel tee, carbon steel tee, copper tee, PVC tee, etc.
1. Straight tee: it is the tee fitting of vertical main pipe of branch pipe.
2. Inclined tee: it is a tee fitting with a certain angle between the branch pipe and the main pipe.
Precautions when purchasing tee
The renovation of waterways is the most important part, which should not be neglected at all. To do a good job in waterway reconstruction, the selection of waterway decoration materials is very important. Many owners may think it’s better to buy a good water pipe. In fact, in addition to the water pipe, various water pipe fittings are also needed during the water transformation. Although these fittings are not impressive, they are indispensable.
(1) First, determine whether the controlled medium is oil or water.
(2) Calculate the flow of controlled medium m3 / h.
(3) According to the controlled medium and its design flow, choose the diameter of three-way temperature regulating valve.
(4) According to the valve body material (cast copper or t cast iron), connection type (f flange, G pipe thread, ZG taper pipe thread), valve structure type (Z rotary valve type, H slide valve type), temperature regulating range and installation type, determine the model of three-way regulating valve.
(5) According to the different flow directions of the three valve ports, the three-way temperature regulating valve can be used in the confluence or shunt control occasions.
(6) The function of the combined three-way temperature regulating valve is to mix two different temperature fluids through the valve into the third temperature fluid whose temperature is between the first two. The valve has two inlets (B is the high temperature inlet, C is the low temperature inlet) and one outlet (a). The temperature sensing element is installed at the outlet (a). The function of the shunt type three-way temperature regulating valve is to divide a kind of fluid into two ways in proportion after passing through the valve. When the valve closes one outlet, it opens another outlet. This valve has one inlet (a) and two outlets (B is the bypass return port, C is the shunt cooling port).
(7) The three-way temperature regulating valve can replace a two-way valve and a three-way connecting pipe.
(8) There are six installation types of rotary valve type three-way temperature regulating valve, which are suitable for any pipe connection. The installation type is selected according to the actual pipe connection of the system.
(9) The three-way temperature regulating valve can be installed at any position, but the emergency manual device surface shall be installed at the position convenient for operation.
(10) In order to prevent the impurities in the medium from jamming or blocking, a filter should be set in front of the three-way temperature regulating valve.
