Abstract
The utility model relates to an integral type reciprocating pump valve. The integral type reciprocating pump valve is composed of a valve body and a valve seat. A metal reinforcing plate is arranged in the valve body. The metal reinforcing plate and an elastic sealing member are vulcanized together to form an integral body. Compared with the existing valve, the integral type reciprocating pump valve has simple structure, convenient installation, and light weight. The opening resistance and the inertia wastage of the integral type reciprocating pump valve are reduced, the suction performance of the integral type reciprocating pump valve is improved, and the service life of the integral type reciprocating pump valve is enhanced.
Description
The utility model relates to the cone valve that drilling pump is used in a kind of reciprocal pump valve, particularly oil drilling and the geological exploration field, and it is made up of valve seat, valve body.
At present, domestic and international widely used Drilling Pump Valve, its structure is made up of valve seat, valve body, valve rubber and gland nut.This class Drilling Pump Valve complex structure uses also inconvenient.This kind valve is when being in free state, and the conical surface of valve rubber exceeds the valve body conical surface 0.3～0.7mm, plays buffer function.During valve work, owing to the souring of liquid stream, make valve rubber damage in advance easily, simultaneously, because the cyclonic action of liquid stream, therefore the also easy back-off of gland nut, causes and directly impacts contact between the metal covering, has influenced the working life of valve.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of structure more simple back and forth pump valve.
The utility model is characterised in that valve body ［ 2 ］ is an integral body, metal reinforcing plates ［ 3 ］ is arranged in the valve body ［ 2 ］, metal reinforcing plates ［ 3 ］ sulfides with elastomer seal ［ 4 ］, elastomeric material is nonmetal, can be polyester, rubber, reach the purpose of this utility model with this measure.This valve does not have gland nut, therefore, and no back-off phenomenon.Because the utility model valve body is whole nonmetallic material, does not produce yet and directly impact contact between the metal.Metal reinforcing plates is arranged, so that valve body has enough impact resistances in the valve body.
Description of drawings:
［ 1 ］ valve seat ［ 2 ］ valve body ［ 3 ］ metal reinforcing plates ［ 4 ］ elastomer seal ［ 5 ］ guide rod
A kind of embodiment of the present utility model, first processing metal stiffening plate, and on stiffening plate 6～18 in staggered hole of boring φ 4～φ 10, again guide rod ［ 5 ］ is welded on the stiffening plate, at last metal reinforcing plates and nonmetallic material are sulfided in mould.
The utility model has the following advantages than prior art:
1. simple in structure, use, easy for installation;
2. weight reduction, minimizing valve body opening resistance and inertia loss improve suction performance;
3. increase the buffer function of valve, improved the working life of valve.
Claims (3)
1, the reciprocal pump valve of a kind of integrated type is made up of valve seat [1], valve body [2], it is characterized in that valve body is an integral body, has metal reinforcing plates [3] in the valve body.
2, valve according to claim 1 is characterized in that metal reinforcing plates ［ 3 ］ and elastomer seal ［ 4 ］ sulfide.
