Abstract
A kind of non-return overflow combiner valve.Mainly solve existing valve interface many, easily leak, safeguard problem frequently.It is characterized in that: in main body (1), have 1 above inlet opening (2) and 1 above delivery outlet (6) and be connected, input relief valve (3) is gone up and be connected with in inlet opening (2), on inlet opening (2), be serially connected with input safety check (4), on delivery outlet (6), be serially connected with output safety check (7), input between safety check (4) and output safety check (7) and be connected with Pressure testing mouth (5).This non-return overflow combiner valve has the advantages that interface is few, be difficult for leakage, maintenance phase length.
Description
Technical field:
The utility model relates to oil extraction in oil field field valve used, especially non-return overflow combiner valve.
Background technique:
In the pipeline of controlling at fluid, often run into safety check, relief valve and pressure gauge etc. and install concentratedly, and single-piece assembling forms many interfaces, is unfavorable for sealing, easily produces and leak, need to safeguard frequently.For better this class problem that solves, designed this non-return overflow afflux assembly.
Model utility content:
In order to solve many, the easy leakages of existing valve interface, to safeguard problem frequently.The utility model provides a kind of non-return overflow combiner valve.This non-return overflow combiner valve has the advantages that interface is few, be difficult for leakage, maintenance phase length.
The technical solution of the utility model is: this non-return overflow combiner valve comprises main body.In main body, there are 1 above inlet opening and 1 above delivery outlet and are connected, on inlet opening and be connected with input relief valve, on inlet opening, be serially connected with input safety check, on delivery outlet, be serially connected with output safety check, input between safety check and output safety check and be connected with Pressure testing mouth.
On Pressure testing mouth in such scheme, be communicated with pressure gauge.
The utlity model has following beneficial effect: this non-return overflow combiner valve is first owing to having 1 above inlet opening and 1 above delivery outlet in employing main body and being connected, on inlet opening and be connected with input relief valve, on inlet opening, be serially connected with input safety check, on delivery outlet, be serially connected with output safety check, input safety check with export between safety check and be connected with the structure of Pressure testing mouth, to input relief valve, input safety check and output safety check are all placed in main body, and then minimizing interface, reducing interface reaches more than 50 percent, greatly extend maintenance period, finally reduce costs.This non-return overflow combiner valve has the advantages that interface is few, be difficult for leakage, maintenance phase length thus.
Accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
1-main body in figure, 2-inlet opening, 3-inputs relief valve, and 4-inputs safety check, 5-Pressure testing mouth, 6-delivery outlet, 7-exports safety check.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this non-return overflow combiner valve comprises main body 1.In main body 1, there are 1 above inlet opening 2 and 1 above delivery outlet 6 and are connected, inlet opening 2 is connected with pipeline with adapter cap by union nut, on inlet opening 2 and be connected with input relief valve 3, input relief valve 3 is comprised of valve ball, overflow spring, seal ring, relief valve body, tightening cap, relief valve valve nozzle, and is placed in main body 1.On inlet opening 2, be serially connected with input safety check 4, input safety check 4 is comprised of valve ball, check spring, seal ring and clamping cap, and is placed in main body 1.Delivery outlet 6 is connected with pipeline with adapter cap by union nut, is serially connected with output safety check 7 on delivery outlet 6, and output safety check 7 is comprised of valve ball, check spring, seal ring and clamping cap, and is placed in main body 1.Input between safety check 4 and output safety check 7 and be connected with Pressure testing mouth 5, on Pressure testing mouth 5, being communicated with pressure gauge.
Claims (2)
