Abstract
The utility model discloses a screw air compressor machine admission valve, including admission valve body, atmospheric valve, solenoid valve, piston chamber, compressed air release pipe, be equipped with the check valve between atmospheric valve and the admission valve, the built-in check valve of admission valve body, the admission valve body is adorned on the base, and the atmospheric valve directly adorns on the base, and the atmospheric valve is connected with holding the accent valve, and the solenoid valve directly adorns on the base. The utility model discloses rational in infrastructure, connect reliably, be difficult for revealing, long service life, the performance is good.
Description
Technical field:
The utility model relates to a kind of screw-rod air compressor gas valve.
Background technique:
Suction valve on the screw-rod air compressor was normally closed piston type in the past, and valve body is arranged, and safety check, piston, piston cavity etc. are arranged in the valve body, valve body has atmospheric valve outward, solenoid valve is arranged on the atmospheric valve, and atmospheric valve is gone into the valve body suction port by external pipeline, discharges pressurized gas in the barrel of oil and gas.Valve body is generally integrated type or combined type, integrated type is made difficulty, and existing combined type valve body is near safety check, be divided into bonnet and following valve body, though this mode processing is simple, but it is unreliable to connect, and the external pipeline of atmospheric valve and valve body causes easily that the joint is loosening, pipe aging, gas leakage in addition, in addition in transportation, be installed to and cause collision, damage tube head in the process on the compressor head easily.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and performance is good, non-damageable screw-rod air compressor gas valve.
Technical solution of the present utility model is:
A kind of screw-rod air compressor gas valve, comprise suction valve valve body, atmospheric valve, solenoid valve, piston, piston cavity, pressurized air releasing tube, be provided with one-way valve between atmospheric valve and the suction valve, loaded check valve in the suction valve valve body, the suction valve valve body is loaded on the pedestal, it is characterized in that: atmospheric valve directly is loaded on the pedestal, and atmospheric valve transfers valve to be connected with appearance, and solenoid valve directly is loaded on the pedestal.
The pressurized air releasing tube of atmospheric valve and valve body suction port is directly cast in the suction valve valve body.One-way valve is housed in the safety check.Suction valve valve body and pedestal are bolted on the air compressor head by same.One-way valve between atmospheric valve and the suction valve is arranged in the valve body.Be provided with seal ring between piston and the piston cavity inwall, be provided with wear ring between piston and the piston cavity inwall.
The utility model is rational in infrastructure, connects reliably, be difficult for revealing, and long service life, performance is good.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Fig. 2 is the plan view of Fig. 1.
Embodiment:
A kind of screw-rod air compressor gas valve, comprise suction valve valve body 1, atmospheric valve 2, solenoid valve 3, piston 4, piston cavity 5, pressurized air releasing tube 6, be provided with one-way valve 7 between atmospheric valve and the suction valve, loaded check valve 8 in the suction valve valve body, the suction valve valve body is loaded on the pedestal 9, and atmospheric valve directly is loaded on the pedestal 9, and atmospheric valve transfers valve 10 to be connected with appearance, solenoid valve 3 directly is loaded on the pedestal 9, connects more reliable like this.The pressurized air releasing tube 6 of atmospheric valve and valve body suction port is directly cast in the suction valve valve body, makes outward appearance easier, does not have unnecessary joint, can not cause leakage.One-way valve 11 is housed in the safety check 8, can eliminates air compressor when unloading because of trembling that vacuum causes.Suction valve valve body and pedestal are bolted on the air compressor head by same, have reduced difficulty of processing like this, and join strength is increased, and be more reliable.One-way valve 7 between atmospheric valve and the suction valve is arranged in the valve body, and is simple in structure, reliable.Be provided with seal ring 12 between piston and the piston cavity inwall, be provided with wear ring 13 between piston and the piston cavity inwall, more effective to have slowed down wearing and tearing, life-span longer.
Claims (6)
1, a kind of screw-rod air compressor gas valve, comprise suction valve valve body, atmospheric valve, solenoid valve, piston, piston cavity, pressurized air releasing tube, be provided with one-way valve between atmospheric valve and the suction valve, loaded check valve in the suction valve valve body, the suction valve valve body is loaded on the pedestal, it is characterized in that: atmospheric valve directly is loaded on the pedestal, and atmospheric valve transfers valve to be connected with appearance, and solenoid valve directly is loaded on the pedestal.
2, screw-rod air compressor gas valve according to claim 1 is characterized in that: the pressurized air releasing tube of atmospheric valve and valve body suction port is directly cast in the suction valve valve body.
