Abstract
The utility model provides a pipe joint used for the coolant side of a plate-side heat exchanger and having simple connection and high sealing performance and pressure bearing capacity. The pipe joint selected from an external screwed pipe is characterized in that an annular sealing groove is formed on the upper end face of the external screwed pipe; and an expanded-connection end edge is arranged at the lower end of the external screwed pipe. During actual connection, the pipe joint can be connected with a pipe joint at the user end by placing a sealing ring in the annular sealing groove of the pipe joint and tightly screwing the pipe joint at the user end. Accordingly, a connection pipe can be connected with the coolant side through the screwed pipe and can be sealed through a sealing ring on the end face, thereby achieving good sealing effect and solving the pressure bearing problem.
Description
Technical field
The utility model relates to a kind of pipe connection, relates in particular to a kind of pipe joint that is used for the plate type heat exchanger refrigerant side.
Background technique
The adapter of the refrigerant side of existing plate type heat exchanger connects, and normally the refrigeration agent copper pipe is inserted in the corresponding adapter of plate type heat exchanger, carries out being welded to connect with silver solder or argon arc welding, to reach the job requirement of sealing and pressure-bearing.In welding process, need heat exchanging device body to cool off, if cool off badly, then cause plate to change leakage easily; And this adapter welding is higher to welder's technical requirements, easily causes product rejection.
Connect if connect to substitute above-mentioned welded pipe with threaded pipe merely, then can't obtain desired sealing.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly connects simple and can reach the enough sealings and the pipe joint that is used for the plate type heat exchanger refrigerant side of pressure-bearing property.
Pipe joint described in the utility model is male-pipe, and the upper-end surface of described threaded pipe is provided with annular seal groove, and the lower end of threaded pipe is provided with expanded joint end limit.
When reality connects, in the annular seal groove of pipe joint described in the utility model, behind the placement seal ring, client end pipe joint and the utility model are screwed, promptly finish connection.
In order further to improve the end face seal performance, can adopt trapezoidal seal ring to insert in the annular seal groove.Described trapezoidal seal ring can be the special-purpose trapezoidal seal ring of a kind of end face that 200720018031 model utilitys are provided.
Adopt the utility model, when the adapter connection of carrying out refrigerant side is carried out, threaded pipe connection and end-face seal ring sealed junction can be lumped together, both reached sealing effect, also solved the problem of pressure-bearing.This kind Placement with respect to traditional welding manner, connects simply, and the possibility that heat exchanger is scrapped is minimum; And in corresponding manufacturing course of working, require also very low to the operator.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model plan structure schematic representation;
Fig. 2: along the sectional structure schematic representation of A among Fig. 1-A direction;
Fig. 3: the client's section pipe joint structure schematic representation that is used with the utility model.
Specific embodiment
As shown in Figures 1 and 2, the utility model is the male-pipe 1 that a lower end has flange 4, and the upper-end surface of male-pipe 1 is provided with annular seal groove 2, and the lower end mouth of flange 4 is provided with expanded joint end limit 3.
As shown in Figure 3, with the client end pipe joint that the utility model is used, be a riffled tube 5, riffled tube 5 have the inner threaded surface 6 that matches with the utility model and with the corresponding sealed upper end face 7 of annular seal groove 2 end faces.
Add man-hour carrying out the plate type heat exchanger end plate, the expanded joint end limit 3 along the lower end of pipe joint described in the utility model with pipe joint described in the utility model and end plate respective apertures place's expanded joint and firm welding, forms plate type heat exchanger end plate refrigerant side pipe joint.
When reality connects, in the annular seal groove 2 of pipe joint described in the utility model, behind the trapezoidal seal ring of placement, client end pipe joint and the utility model are screwed, promptly finish connection.
