Description

Disalignment abnormity pressure communication channel structure in cylinder housing
Technical field
The utility model discloses a kind of disalignment abnormity pressure communication channel structure be applicable in cylinder housing, belong to Machine Design and manufacture field.
Background technique
Need to be driven equipment by pressure conduction or control in some engineering goods.Especially the engineering goods limited for some overall volume, design space is limited, more particularly need the engineering goods of pressure communication channel design in housing, its design space is very limited.Conventional design method innerly installs pipeline, or holes drilled through connects each and needs conducting pressure region.Such as, China Patent No. " 200780037402.7 " discloses a kind of pressure transfer device for pressure energy to be delivered to low-pressure fluid flow from high pressure first fluid stream, publication date is 2009-10-28, wherein general cylindrical shape housing accommodates and has turning of multiple passage, described passage extend through rotor axial and around central stator or around sleeve in turn round, and a pair end cap slides and meets boundary with the respective planes end face of rotor hermetically.The appurtenances of end cap and device are configured to fill at least twice at often turn around period each passage high pressure first fluid of rotor, and therefore give off the second liquid of the pressurization of two volumes when only filling a time with high-pressure liquid.
But in actual applications, be generally not easy to when housing is thinner pipeline is installed, or due to structural design needs, be also not easy to directly bore straight line pylone.Such as, under the surface of housing, different depth place is designed with different pressure spans, need latus rectum by these two regional connectivities, because processing space is limited between this, directly can not drill with deep hole drill, also cannot lay pressure line, this is just for pressure communication channel design brings difficulty.
Summary of the invention
The purpose of this utility model is the problems referred to above overcoming prior art existence, provides the structure of the disalignment abnormity pressure communication channel in a kind of cylinder housing.The utility model achieves the connection of different depth straight hole under shell skin, and can guarantee to be communicated with effectively.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Disalignment abnormity pressure communication channel structure in a kind of cylinder housing, it is characterized in that: comprise housing, two straight holes are provided with in described housing, annular pass is provided with between two straight holes, two straight hole one end are communicated with annular pass respectively, and the other end is communicated to the pressure span at different depth place respectively.
Described housing is made up of upper connection and lower contact, upper connection and lower contact are sealedly and fixedly connected, upper connection straight hole and upper connection circular groove is provided with in upper connection, upper connection straight hole is communicated with upper connection circular groove, lower contact straight hole and lower contact circular groove is provided with in lower contact, lower contact straight hole is communicated with lower contact circular groove, and upper connection circular groove is communicated with formation annular pass with lower contact circular groove, and upper connection straight hole and lower contact straight hole are communicated to the pressure span at different depth place respectively.
Described upper connection and lower contact are threaded, and joint is provided with seal ring.
Described upper connection straight hole and lower contact straight hole are not on the same line.
Employing the utility model has the advantage of:
One, the utility model comprises housing, two straight holes are provided with in described housing, annular pass is provided with between two straight holes, two straight hole one end are communicated with annular pass respectively, the other end is communicated to the pressure span at different depth place respectively, adopt this structure to achieve the connection of different depth straight hole under shell skin, and can guarantee to be communicated with effectively.
Two, the utility model is provided with the minor diameter straight hole of two different depths in housing, straight hole has been communicated with two pressure spans that different depth place needs under surface of shell link together respectively, article two, the minor diameter straight hole of different depth is communicated with by an annular pass with the surface of contact of lower contact in upper connection, achieve the connection of different depth straight hole under shell skin, and can guarantee when upper connection links together with lower contact to be communicated with effectively.
Three, the utility model is adding man-hour by upper and lower joint junction surface brill straight hole and processing circular groove, processes convenient.
Four, in the utility model, upper connection circular groove is communicated with formation annular pass with lower contact circular groove, achieve the connection of different depth straight hole under shell skin, not only can guarantee when upper connection links together with lower contact to be communicated with effectively, and ensure that the effective connection of two straight holes under any angle of swing.
