Description

The quick access device of valve body valve port and pipe fitting

Technical field

The utility model relates to the connection set of a kind of valve body valve port and pressure pipe fitting, especially refers to the fast access node structure technology of this connection set.

Background technique

In pneumatic and technical field of hydraulic elements, valve body often is provided with a plurality of valve ports, and people are connected by these valve ports and pipe fitting, and pneumatic or hydraulic pressure signal source are delivered to the mechanical function parts to realize automatic control.The early stage valve body valve port and the Placement of pipe fitting are fairly simple, only process internal thread in valve port, and the outside thread with pipe fitting end directly is rotatably connected in the valve port then, mounts and dismounts cumbersome.The someone had invented a kind of quick access device afterwards, relatively more typical as State Intellectual Property Office in notice of authorization on August 29 calendar year 2001, the patent No. is called " connecing straight-through pipe fitting and valve soon " utility model patent product for the ZL00260211.3 name, it " is equipped with Sealing; fastening piece is connected with link; have rational in infrastructure; easy for installation; processing is simple; with low cost successively on the tube head on connecting tube top, sealing is strong, latus rectum is constant, flow is unobstructed, pipeline is not made silk, connect characteristics such as fast firm, traditional pipe fitting and valve processed complex have been solved, trouble is installed, of poor quality, problems such as the life-span is short have been simplified the operation that pipeline connects." just the Placement of this product still continue to use engage thread and connect, pipe fitting needs certain distance that moves axially when dismounting, so be difficult to be applied to the pneumatic or hydraulic pressure installation that part valve body mounting point compactness, the axial spare bits of connection pipe fitting are equipped with limit.

The model utility content

The technical problems to be solved in the utility model is defective and the deficiency that is applied to being difficult to of overcoming that existing like product exists in the pneumatic or hydraulic pressure installation that part valve body mounting point compactness, the axial spare bits of connection pipe fitting be equipped with limit, provide a kind of need to vertically move the quick access device that can finish the pipe fitting dismounting to society, satisfying part valve body mounting point compactness, the axial spare bits of connection pipe fitting, to be equipped with the supporting application of pneumatic or hydraulic pressure installation of limit required.

The technological scheme that its technical problem that solves the utility model adopts is: the quick access device of valve body valve port and pipe fitting, the piece that connects that comprises the valve port of valve body and connection pipe fitting, the described piece dual-side that connects is connected to fixture block by screw threads, and the wedge dop of symmetry is established at described fixture block two ends; The described piece dual-side that connects is provided with and the corresponding wedge groove of described wedge dop, and the wedge draw-in groove of symmetry is established in described valve port both sides, and described wedge draw-in groove is corresponding with described wedge dop; The described piece end face that connects is embedded seal ring.

Cross groove is established in described valve port lower end, describedly connects the end face lower edge that piece is embedded described seal ring and is provided with flange.

The quick access device of the utility model valve body valve port and pipe fitting, the piece that connects that connects the pressure pipe fitting is vertically to connect valve port from valve body top; By the described cross groove that piece lower edge flange snaps in described valve port lower end correspondence, the vertical height position consistency that assurance is installed of connecing; Again by screwing the screw of both sides, the wedge draw-in groove inclined-plane that utilizes described wedge dop and described valve port both sides is with valve port end face, seal ring and connect piece and be strained and fixed the valve port after guaranteeing to install and the coaxality of pipe fitting.This product mounts and dismounts the pressure pipe fitting by vertically moving the mode that connects piece, is particularly suitable for the pneumatic or hydraulic pressure installation that part valve body mounting point compactness, the axial spare bits of connection pipe fitting be equipped with limit and uses.Compare than existing product, this product has simple in structure, easily manufactured advantage.

Embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, the quick access device of the utility model valve body valve port and pipe fitting comprises with the pipe fitting end screw thread joins connecing piece 6 that described piece 6 one ends that connect are established internal thread 11, the other end is embedded seal ring 5, and the edge, below of described seal ring 5 is provided with flange 10; Described piece 6 dual-sides that connect are connected with fixture block 7 by screw 8, and the wedge dop 9 of symmetry is established at described fixture block 7 two ends; Described piece 6 dual-sides that connect are provided with and described wedge dop 9 corresponding wedge grooves 12; Establish the wedge draw-in groove 2 of symmetry in valve port 3 both sides of valve body 1, cross groove 4 is established in described valve port 3 lower ends.

Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.During installation, end thread with the pressure pipe fitting is tightened in the described internal thread 11 that connects piece 6 in advance, unscrew two screws 8 then, the described fixture block 7 that connects piece 6 dual-sides unclamps, vertically that the wedge dop 9 of described fixture block 7 one ends is corresponding with the wedge draw-in groove 2 of described valve port 3 both sides along valve body 1 top; In the process that moves down, described the join end face lower edge flange 10 of a side of piece 6 and valve port 3 that connects snaps in the corresponding cross groove 4 in described valve port 3 lower ends, has guaranteed the vertical height position consistency of valve port and pipe fitting.Screw the outer screw 8 of described fixture block 7 then respectively, wedge draw-in groove 2 inclined-planes that utilize described wedge dop 9 and described valve port 3 both sides are with valve port 3 end faces, seal ring 5 and connect piece 6 and be strained and fixed, and guaranteed the left and right horizontal position consistency of valve port and pipe fitting simultaneously.
