Problems solved by technology

[0002] The straight-through valve seat is a part in the valve, which is used to support the fully closed position of the valve core and form a seal. Generally, the diameter of the valve seat is the maximum flow diameter of the valve. It is used to control the flow of fluid or change the flow of fluid in the fluid control pipeline. The flow direction has a good use effect, but the existing straight-through valve seat has certain shortcomings that need to be improved; the existing straight-through valve seat has certain disadvantages in use, and the existing straight-through valve seat usually adopts a The elastic sealing material is used for sealing, and it is usually a split structure. Under long-term use of this structure, the aging of the sealing material will cause water leakage, the sealing effect will be affected, and the use effect is average, which brings certain disadvantages to actual use. Therefore, we propose an integral straight-through valve seat for ultra-high pressure plunger pressure pumps for shale gas exploitation

Abstract

The invention discloses an integral straight-through valve seat for an ultrahigh-pressure plunger pressure pump for shale gas extraction. The integral straight-through valve seat comprises a valve seat body, a first water inlet is formed in the surface of one side of the valve seat body, a first water outlet is formed in the surface of the other side of the valve seat body, a second water inlet isformed in the front surface of the valve seat body, and a second water outlet is formed in the rear surface of the valve seat body. A turn-on opening is formed in the lower surface of the valve seatbody, the outer surface of the valve seat body is coated with antirust coating, the valve seat body is of an integral structure, and the first water inlet is communicated with the first water outlet.According to the integral straight-through valve seat for the ultrahigh-pressure plunger pressure pump for shale gas extraction, the whole valve seat is changed into the integral structure, compared with a traditional split structure, the parallelism precision of a sealing face is easier to guarantee, and the sealing effect is better. Meanwhile, the situation that due to the fact that a traditional sealing material is aged, water leakage is caused is avoided, it is avoided that repairing work is increased, use is more convenient, higher practicality is achieved, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of straight-through valve seats, in particular to an integral straight-through valve seat for an ultra-high pressure plunger pressure pump used in shale gas exploitation.
