Detailed description of the invention

See shown in accompanying drawing 1-4.

A kind of overall-in-one control schema valve group, including safety valve, check (non-return) valve, ball valve, is characterized by: described safety valve include nameplate 1, Snap ring 2, bonnet 3, adjusting screw rod 4, ABS clamping cap 5, spring compression ring 6, push rod 7, compression spring 8, abs valve lobe 9, rubber Glue flap 10, integrative valve body 11；Described check (non-return) valve B include bonnet the 12, first O 13, compression spring 14, flap 15, Second O 16, valve seat the 17, the 3rd O 18；Described ball valve include PTFE valve seat 19, spool 20, PTFE valve seat 21, Plug 22, valve rod the 23, the 4th O 24, screw 25, handle 26, connection swivel nut 27；Abs valve in wherein said safety valve Lobe 9 and rubber flap 10 are seated in integrative valve body 11, and bonnet 3 is threaded connection with integrative valve body 11, and by rubber valve Lobe 10 is pressed in valve body, and compression spring 8 is placed in the cavity of abs valve lobe 9, and there is a spring compression ring 6 upper end, adjusting screw rod 4 with ABS clamping cap 5 is threaded connection, and the end of adjusting screw rod 4 is placed on spring compression ring 6, rotates adjusting screw rod 4 thus drives Spring compression ring 6 lifts, thus regulates the pretightning force of compression spring 8.

Operation principle is as follows:

When being in normal operational condition by protection system, the compression spring 8 in safety valve is utilized to act on abs valve lobe 9 and rubber Power on flap 10, makes rubber flap 10 be in closedown, sealing state.The decrement of compression spring 8 can be by rotating above it Adjusting screw rod 4 regulate, utilize this structure just can correct the unlatching pressure of safety valve as required.When system pressure liter Up to when opening pressure, abs valve lobe 9 and rubber flap 10 are backed down, and a part of compressed air i.e. enters air from valve port；When When bleed pressure is less than safety value, compression spring 8 drives abs valve lobe 9 and rubber flap 10 to move down, close port.

In check (non-return) valve, bonnet 12 is connected with integrative valve body 11 by screw thread, and by the second O 16, valve seat the 17, the 3rd O Shape circle 18 is pressed in integrative valve body.Flap 15 is seated on the sealing surface of valve seat 17.Flap 15 can freely lift, stream Body pressure makes flap 15 lift from valve seat 17 sealing surface, and medium back flow causes flap 15 to fall back on valve seat 17, and cuts off flowing. According to the condition of use, flap can be all-metal construction, it is also possible to be the form inlaying rubber blanket or rubber ring on valve petal shelf.

In ball valve, connect swivel nut 27 and be threaded connection with integrative valve body 11, and by PTFE valve seat 19, spool 20, PTFE Valve seat 21 is pressed abd fixed on integrative valve body 11, and handle 26 and valve rod 23 is fixed as one by screw 25, valve rod 23 square Head coordinates with the square opening of spool 20, when handle 26 band ovable valve stem 23 rotates, then spool 20 is driven by valve rod 23, and around ball valve axle Line rotates, it is achieved the opening and closing of ball valve 3.

These control valve group two ends are threaded connection and are connected with channel bend.

Elaborate a lot of detail in the above description so that fully understanding the utility model.But above description is only this The preferred embodiment of utility model, the utility model can implement to be much different from alternate manner described here, because of This utility model is not limited by disclosed above being embodied as.The most any those skilled in the art are without departing from this reality In the case of new technique aspects, technical solutions of the utility model are done by the method and the technology contents that all may utilize the disclosure above Go out many possible variations and modification, or be revised as the Equivalent embodiments of equivalent variations.Every without departing from the utility model technical side The content of case, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, All still fall within the range of technical solutions of the utility model protection.
