Abstract
The utility model relates to a valve seat for a petroleum drilling slurry pump. The top of the valve seat is provided with a supporting slot matched with a supporting part of a valve body. The supporting slot comprises a supporting plane and a supporting conical surface. The center of the supporting plane is provided with a guide slot for installing a valve body guide device. The valve seat for the petroleum drilling slurry pump has reasonable structure design. The valve seat is provided with the supporting plane and the supporting conical surface. An original conical surface single support mode is changed into a plane and conical surface double-supporting mode, so that the contact surface of the valve body and the valve seat is increased and the impact of the valve body to the valve seat is reduced. The using effect is good. The service life is greatly prolonged. The time for stopping the pump to change parts is shortened. The drilling efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of mud pump for petroleum drilling accessory, particularly a kind ofly is used for the valve seat that mud pump for petroleum drilling is used.
Background technique
Valve body, valve seat are the kernel components in the fluid end clack box parts, and in use, valve body acts on up and down, and what the active force of the supporting portion on the valve body was frequent impacts on the support conical surface of valve seat, and the support conical surface of valve seat is subsided, and cause damage.Because the unreasonable valve seat that causes of structural design is short working life, needs often to change, and has directly influenced drilling efficiency.
The model utility content
The purpose of this utility model is at above-mentioned shortcoming and defect, and a kind of mud pump for petroleum drilling valve seat of reasonable in design long service life is provided.
The technical solution of the utility model is: a kind of mud pump for petroleum drilling valve seat, the top of described valve seat is provided with the support slot that matches with the supporting portion of valve body, described support slot comprises supporting plane and supports the conical surface that the center of supporting plane is provided with the guiding groove that the valve body guiding device is installed.
Preferably: the support conical surface of described valve seat is 45 ° the support conical surface.
Preferably: described valve seat is set to taper type.
The beneficial effects of the utility model are: the utility model reasonable in design, valve seat is provided with supporting plane and supports the conical surface, with the original support becoming of the conical surface list plane and conical surface dual-gripper face, increased the area of contact of valve body and valve seat, reduced the impact of valve body to valve seat, using effect is good, and improve working life greatly, shortened termination of pumping and changed the part time, drilling efficiency is significantly improved.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model:
As shown in Figure 1, valve body 1 of the prior art is installed on the valve seat 2, and the supporting portion 3 of valve body 1 is merely able to contact with the support conical surface on the valve seat 2, because valve body 1 acts on up and down, what active force was frequent impacts supporting on the conical surface 5, often causes supporting the conical surface easily and subsides, and causes damage.
As shown in Figure 2, a kind of mud pump for petroleum drilling valve seat 2, the top of described valve seat 2 is provided with the support slot 6 that matches with the supporting portion 3 of valve body, described support slot 6 comprises supporting plane 7 and supports the conical surface 5 that the center of supporting plane 7 is provided with the guiding groove 8 that valve body 1 guiding device 4 is installed.The support conical surface 5 of described valve seat is 45 ° the support conical surface.Described valve seat 2 is set to taper type.
Above illustrated embodiment is only with for conveniently illustrating the utility model, and at technological scheme category described in the utility model, the person of ordinary skill in the field does various simple deformation and modification, all should be included in the above claim.
