Abstract
The utility model relates to a quick joint for making one-way valve forepart can not to contain pilot valve when system or pipe line has pressure, which comprises a positive connector and a negative connector connected with the positive connector via an O-shape sealed ring 8. Steel balls 9 in the negative connector runs into a V-shape groove provided on the positive connector 14 under the force of an outer sleeve. A negative pusher bar 6 is oppositely contacted to a positive pusher bar 12 to compress a pair of one-way valves 3 respectively provided at the end thereof fallback. The positive connector is communicated with the negative connector. The utility model has the advantages of quickly connection and reliably connection is achieved when system has pressure. The quick joint can not be broken when system has pressure so that a reliably connection is achieved. The main valve of the utility model has a lead valve to divide the main valve into a frontal portion and a rear portion, wherein the lead valve is placed at the rear portion of the main valve instead of the frontal portion thereof that has not enough space. The structure of the utility model has the same size with the conventional quick joint without pressure function so that the utility model can be substituted for the conventional quick joint but achieves basic performance, qualification and external shape of the conventional quick joint.
Description
Technical field
The utility model relates to the rapid pipe joint technical field, and the one-way valve leading portion can't hold the rapid pipe joint of pilot valve when specifically a kind of system or pipeline had pressure.
Background technique
Rapid pipe joint is a kind of any instrument that neither needs to use, can realize fast quick-mounting, the pipe joint of tearing open again, and the rapid pipe joint of two ends band one-way valve does not almost have working medium to flow out when disconnecting and does not almost have air to sneak into when being connected in the pipeline, be widely used in hydraulic pressure, Pneumatic Transmission and lubricate, in the fluid delivery pipeline system such as water cooling.
The rapid pipe joint of traditional two ends band one-way valve after disconnection because the overbottom pressure (when especially being medium with liquid) in system or the pipeline causes one-way valve to open, so usually wanting that earlier system or pipeline are bled off the part medium connects to discharge overbottom pressure again, thereby limited the quick advantage of joint, more can't satisfy some usage requirement that needs rapid pipe joint still can reliably connect when system or pipeline have pressure (working pressure or overbottom pressure).
Summary of the invention
The purpose of this utility model is that a kind of system or pipeline realized of design has the reliable connection when pressing; The having of model specification that keep being correlated with is with the pressure linkage function to press the consistent of two kinds of joint Conncetion cimension of linkage function with not having band, and the one-way valve leading portion can't hold the rapid pipe joint of pilot valve when the system of realization exchange or pipeline had pressure.
The one-way valve leading portion can't hold the rapid pipe joint of pilot valve when the utility model system or pipeline had pressure, and comprising: negative joint comprises; Spring is housed in the end connector, in the negative joint body check valve body is housed, spring and pilot valve pearl (ball valve or cone valve), negative joint push rod are housed in the check valve body, and negative joint body and end connector be with being threaded, and seal with O-ring seals, steel ball is contained in the taper hole of negative joint, outer casing spring is enclosed between the internal diameter of the external diameter of negative joint body and overcoat, and overcoat is enclosed within on the external diameter of negative joint body, can endwisely slip, jump ring is stuck on the jump ring groove of negative joint body, and blocks overcoat.
Male connector comprises: spring is housed in the end connector, guide's valve ball (ball valve or cone valve) and spring are housed in the male connector body, male connector body and end connector be with being threaded, and seal with O-ring seals.
When being connected with negative joint, male connector seals by O-ring seals, the plurality of steel balls that is circle distribution on the negative joint body radially contracts to when overcoat moves to right in the V-shaped groove of male connector body, the negative joint push rod contacts with the male connector push rod the top, the two ends check valve body is retreated simultaneously, and the internal channel of yin, yang joint is connected.
Pilot valve comprises: ball valve or cone valve, guide's spring.
Outer jacket member comprises: be contained in outer casing spring and jump ring on the negative joint body, steel ball.
One-way valve (main valve, below complete with) respectively is housed in the yin, yang joint, when in the V-shaped groove of radial contraction at male connector under the effect of the plurality of steel balls on the negative joint at overcoat, realizes the connection of rapid pipe joint, this moment, the one-way valve at two ends was opened voluntarily, connected passage; When radial separation under the effect of the plurality of steel balls on the negative joint at overcoat goes out in the V-shaped groove of male connector, realize the disconnection of rapid pipe joint, this moment, the one-way valve at two ends was closed closed channel voluntarily.
The very little one-way valve of guide effect and area (pilot valve, below complete with) has been housed on the main valve, and after opening pilot valve earlier system or pipeline being bled off the part medium and discharge overbottom pressure, main valve gets final product smooth opening, thereby implements to connect.
The advantage that the utility model system or pipeline have one-way valve leading portion when pressing can't hold the rapid pipe joint of pilot valve is: expand the rapid pipe joint function, there is the reliable connection when pressing in the realization system; Can not be disconnected when system or pipeline have the rapid pipe joint of when pressure, keep the reliability that connects; The rapid pipe joint of this structure is because the main valve front end can't hold pilot valve, so main valve is divided into forward and backward two sections, back segment installs pilot valve additional, does not have band with the same model specification and presses the joint of linkage function to keep Conncetion cimension in full accord, all can realize reliable the exchange; Do not change rapid pipe joint key property, technical order and external shape before this.
Description of drawings
The one-way valve leading portion can't hold the quick coupling structure schematic representation (coupled condition) of pilot valve when Fig. 1 pressed for system or pipeline have.
