Abstract
The utility model relates to an easy dismounting fluid pipeline joint structure which is particularly suitable for a connection between a hydraulic pressure oil tank oil return filter and a valve base and also applied to a butt joint of a pipeline of a movable joint between fixed parts in middle and low pressure fluid systems. A simple connecting tube is adopted to simplify a multilevel sealing pipe thread into one level sealing pipe thread arranged at one end of the connecting tube, thereby reducing connection step and lowering oil leakage rate. The other end of the connecting tube is sealed in a sliding mode. When being installed and dismounted, the connecting tube automatically advances or withdraws by utilizing degree of tightness of the thread, and the sliding sealed end can freely extend and withdraw in a hole on a connecting piece, thereby bringing convenience to installing and dismounting. The easy dismounting fluid pipeline joint structure comprises the connecting pipe, a sealed ring and the connecting piece, wherein the oil return filter and the connecting piece are connected and sealed by the connecting pipe and the sealed ring.
Description
Technical field
The utility model provides a kind of easily detachable pipeline jointing construction, is specially adapted to connecting between hydraulic oil container return filter and the coupling, also can be used for the butt joint of pipeline between the mesolow fluid system fixed block.
Background technique
In fluid system, need frequent pulling down cleaning and safeguard that it is very high to the operation requirement in common structure, to dismantle and install these pipelines as parts such as filters, and need certain professional technique ability.Shown in Figure 1 as in the public technology: connecting between dumping car hydraulic oil container return filter and the valve seat; Can change for guaranteeing return filter 9; Make things convenient for filter core 11 to pull down cleaning, in the connection of return filter 9 and coupling 10, adopted and docked that 3,4,5,6 four parts of nut type union assembly and reducer pipe connect 1, straight coupling 2, take over 7 and weld seam 8 form jointly.Because connection and sealing part have more than 7 places, cost is high, and dismounting is numerous and diverse and generation leakage of oil probability is also very high.
Summary of the invention
The problem that the utility model solves is: a kind of easily detachable fluid circuit joint structure is provided.
A kind of easily detachable fluid circuit joint structure is characterized in that: comprise adapter, seal ring and coupling, with adapter, seal ring return filter and coupling are realized connecting and sealing.
The utility model characteristic is: 1. reduced connection sealing configuration quantity, reduced the leakage of oil probability.2. the other end of taking over and coupling are formed slipper seal, utilize screw thread rotation that it is axially moved in the coupling hole during mounting or dismounting, convenient mounting or dismounting.
Description of drawings
Shown in Figure 1 be the tank drainback filter with valve seat between the known technology structural representation that connects.1 reducer pipe connects, 2 straight couplings, 3,4,5,6 nut type union assemblies, 7 adapters, 8 weld seams, 9 return filters, 10 couplings, 11 filter cores.
Fig. 2 is the easily detachable fluid circuit structural representation of the utility model.1 adapter, 2 seal rings, 9 return filters, 10 couplings, 11 filter cores, 102-spanner groove, 101-screw thread.
Fig. 3 is the partial enlarged view at mark 14 places among Fig. 2, the 103-seal channel.
Embodiment
One of specific embodiments of the utility model is as shown in Figures 2 and 3: with take over 1,2 pairs of return filters 9 of seal ring connect with coupling 10 realizations and seal; When needs are dismantled, block spanner groove 102 with spanner, unclamp screw thread 101, and make and take over 1 A point and be inserted to the B point, 101 ports retreat to the just replaceable return filter in N-N cross section 9, cleaning filter core 11; During assembling then threaded together make and take over 1 and be anchored on the A point.
Described adapter 1 adopts the standard pipe moulding mixture directly to process, and connects sealed type pipe thread 101 according to the interface thread of return filter 9.
Described adapter 1 is provided with spanner groove 102 for ease of loading and unloading.
Described adapter 1 is provided with the seal channel 103 that seal ring is installed for the sealing that realizes the other end.
Described adapter 1 is provided with spanner groove 102 also hexagonal shaped or from all directions shape for ease of dismounting.
Described adapter 1 also can be arranged on the hole wall of coupling 10 for the sealing that realizes the other end is provided with the seal channel that seal ring is installed, then take over 1 seal groove place and about be processed as smooth cylindrical.
Claims (2)
