Compared with prior art, the utility model has the following beneficial effects:
The bar shaped screw thread adjustable plate of the utility model is connect with valve chamber inner thread, and the precession that screw thread adjustable plate can be changed is deep Degree carrys out the compression degree of adjustment spring, to play the role of adjusting the conducting pressure of check valve;One-way sealing spool is by sealing Head and bar portion composition, bar portion are threaded through in spring and screw thread adjustable plate, can play guiding role well, can prevent spring from losing Surely, also it can prevent seal head skew from causing sealing tight;The utility model structure is simple, and various pieces are all connected through a screw thread, It is convenient to disassembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the screw thread adjustable plate structural schematic diagram of the utility model.
Wherein, the corresponding title of appended drawing reference are as follows:
1- valve chamber, 2- valve body, 3- screw thread adjustable plate, 4- spring, 5- imbibition import, 6- connector, 7- imbibition outlet, 8- are logical Hole, 9- seal head, 10- bar portion, the first sealing ring of 11-, the second sealing ring of 12-.
Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, the embodiments of the present invention Include but are not limited to following embodiment.
As shown in Figure 1, a kind of fire-fighting suction type proportion mixer adjustable pressure check valve, including it is interior equipped with valve chamber 1 Valve body 2, one-way sealing spool, screw thread adjustable plate 3 and spring 4 in valve chamber 1 be set, and setting is in 2 front end of valve body and and valve The imbibition import 5 that chamber 1 is connected to, and the connector 6 being threadedly coupled with 2 rear end of valve body.
Wherein, 6 one end of connector is provided with connects with the matched external screw thread of the internal screw thread of valve chamber 1 and the end and 2 screw thread of valve body It connects, 6 other end of connector is provided with external screw thread, is used for external equipment, second for sealing is provided between connector 6 and valve body 2 Sealing ring 12;One-way sealing spool include seal head 9 and with the integrally formed bar portion 10 of seal head 9, screw thread adjustable plate 3 is provided with Mounting hole, mounting hole aperture are slightly larger than 10 diameter of bar portion, can play the role of being oriented to the axial direction that bar portion 10 is also convenient for bar portion 10 Mobile, bar portion 10 sequentially passes through spring 4 and mounting hole setting, and connector 6 axially penetrates through the imbibition outlet for being provided with and being connected to valve chamber 1 7,1 inner wall of valve chamber is provided with internal screw thread, screw thread adjustable plate 3 be provided with the matched external screw thread of internal screw thread and with 1 inner wall spiral shell of valve chamber Line connection, screw thread adjustable plate 3 are provided through the through-hole 8 passed through convenient for gas, and valve chamber 1 is divided into and is inhaled by screw thread adjustable plate 3 The imbibition chamber and the water conservancy diversion chamber being connected to imbibition outlet 7, through-hole 8 that liquid import 5 is connected to are connected to imbibition chamber and water conservancy diversion chamber, Diameter is greater than 5 internal diameter of imbibition import in imbibition chamber room, and is equipped with the necking section mistake from imbibition chamber to imbibition import 5 therebetween It crosses, seal head 9 is tapered and taper and the matching of necking section taper, 9 diameter of seal head are greater than 10 diameter of bar portion, are formed therebetween Cushion cap face, spring 4 is between screw thread mounting plate 3 and cushion cap face and seal head 9 is pushed to fill in the closure imbibition import 5 of necking section.
