Abstract
A transmission enhancing grinding one-way valve includes a valve seat, a valve ball and valve-oriented packages. The valve is characterized in that the seat (1) is the sub-structure, and the hole of the seat is embedded with the carbide central (5).
Description
Technical field:
The utility model relates to valve, particularly one-way valve.
Background technique:
Be used to carry the one-way valve of tempering property medium by force to be the common one-way valve of general structure at present, and by force tempering property medium because its nature and characteristic, this class medium is in the valve events process, especially when valve fell valve seat after rise, the high speed of medium refluxed valve and valve seat is produced strong erosion, very easily causes the damage of valve or valve seat, no matter be valve or valve seat damage, all need to change whole one-way valve, on the whole, be used to carry the one-way valve of tempering property medium by force very low working life.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of one-way valve of tempering property medium by force of carrying is provided, and rational in infrastructure simple, wear resistance is strong, long service life.
The technological scheme that the utility model is adopted for achieving the above object is: carry the one-way valve of tempering property medium by force, comprise valve seat, valve ball and valve guide sleeve, valve seat is for dividing body structure, and the valve seat orifice place is inlaid with carbide ring.
Described valve ball is ceramic valve ball.
Described valve seat and valve guiding hollow pin link into an integrated entity.
Be set with the valve guide sleeve in the described valve seat and fix by gland; Sealing gasket is equipped with in the valve seat outside.
The utility model is at the one-way valve damageable zone, it is the valve seat orifice place tungsten carbide button ring that valve seat contacts with valve ball, because Hardmetal materials is wear-resisting especially material, therefore reduce wear, prolong its working life, other parts of valve seat still adopt general seat material, also minimize cost when guaranteeing wear-resisting property, in addition, valve ball is selected ceramic valve ball for use, the pottery valve ball is not only very wear-resisting, and it is bright and clean, has self-cleaning property, and the two is used the wearing and tearing that guaranteed to greatly reduce valve, increase the service life, when being used for high-pressure delivery, valve seat is connected with valve guiding hollow pin, when being used for low-pressure delivery, suit valve guide sleeve and be connected and fixed the valve guide sleeve by gland and valve seat in the valve seat assembles easy to use.The experiment proved that the working life of the utility model one-way valve is than improving nearly a hundred times the working life of common one-way valve.
Description of drawings:
Fig. 1 is the utility model high pressure valve structural representation.
Fig. 2 is the utility model low pressure valve structural representation.
Embodiment:
Conveying as shown in Figure 1 is the high pressure one-way valve of tempering property medium by force, valve seat 1 is fixedlyed connected by straight pin 4 with valve guide sleeve 3 and is constituted valve pocket, ceramic valve ball 2 is housed in the valve pocket, valve seat is for dividing body structure, rigidity valve seat valve seat orifice place is inlaid with carbide ring 5, and carbide ring can be that the high abrasion resisting material of different shape is made.
Conveying as shown in Figure 2 is the low pressure check valve of tempering property medium by force, be set with " n " type valve guide sleeve 3 in the valve seat 1, gland 6 is fixedly connected to form valve pocket then, ceramic valve ball 2 is housed in the valve pocket, valve seat is for dividing body structure, the valve seat orifice place is inlaid with carbide ring 5, and sealing gasket 7 is equipped with in the valve seat outside, sealing during convenient the use.
Claims (5)
1, carry the one-way valve of tempering property medium by force, comprise valve seat, valve ball and valve guide sleeve, it is characterized in that: valve seat (1) is for dividing body structure, and the valve seat orifice place is inlaid with carbide ring (5).
