Abstract
The invention relates to a novel coal powder conveying angle valve, which comprises a valve core body (3). The novel coal powder conveying angle valve is characterized in that a groove is formed at the upper end of the valve core body (3), so that the valve core body (3) is connected with a valve stem (1); a flow passage is arranged at the lower end of the valve core body (3), so that a medium can flow through the valve core body; and the inner surface of the flow passage is a curved surface. By adopting the valve core of the novel coal powder conveying angle valve, the phenomenon that the valve core is damaged by scouring can be avoided, the flow capacity of the medium is improved and the occurrence of blockage is prevented; and the use proves that when the valve core of the novel coal powder conveying angle valve is used, the flow capacity of the control valve can be increased, the adjusting precision of the control valve can be improved, and the service life of the control valve is prolonged from original one month to one year, so that economic benefits of an enterprise are greatly increased.
Description
Technical field
The present invention relates to a kind of new coal powder and carry angle valve.
Background technique
The coal dust that uses is at present carried in the angle valve design; Adopt the straight passage design like Fig. 1, spool shown in 2; Connect the outlet port and have straight groove type runner, the spool nitriding is handled, and hardness has only HRC40-50; Be illustrated in figure 3 as mounting point and the operating principle of this spool in valve body, it is groove type that spool is regulated the port.Medium (coal dust) is when the spool, and is more and more serious to washing away of spool along with the increase of aperture, produces at the bit point of groove and destroys obscission (A place in destruction region in referring to Fig. 3), thereby greatly reduce the working life of valve.Have only about one month general working life, thereby directly the working life of deck valve and the economic benefit of factory are put in order in influence.
Summary of the invention
A kind of new coal powder that the purpose of this invention is to provide a kind of long service life is carried angle valve.
A kind of new coal powder is carried angle valve, comprises the spool body, and its specialization is, is connected with valve rod thereby said spool body upper end has groove, thereby and be provided with runner in spool body lower end and supply medium to circulate, and this runner internal surface is a curved surface.
Wherein runner exit place, spool body lower end is a rectangle, and four jiaos of this rectangle are arc angling.
Wherein the groove of spool body upper end is not communicated with the runner of spool body lower end mutually.
Adopt spool of the present invention can avoid spool, improve the negotiability of medium, prevent obstruction because of washing away the phenomenon of destroying; Through using proof; Spool of the present invention in use can make the negotiability of control valve increase, and degree of regulation improves; Extended to one year by original one month working life, improved economic benefit of enterprises greatly.

Embodiment
Like Fig. 4, shown in 5; A kind of new coal powder is carried angle valve, comprises columned spool body 3, and is (convenient for describing in spool body 3 upper ends; With an end that is connected with valve rod 1 on the spool body 3 is the upper end; The corresponding the other end then be the lower end, and with accompanying drawing 4,5,6 in upper and lower to being consistent) thereby in the middle of have groove and be connected with valve rod 1, thereby and be provided with runner confession medium in spool body 3 lower ends and circulate; And this runner internal surface is a curved surface, thus the identical medium circulating resistance that reduces of the bending direction of this curved surface with the medium circulating direction.
As shown in Figure 6, spool body 3 is installed in the valve body 2, and spool body 3 lower ends cooperate with valve seat 4 play open, the effect of closed dielectric circulation.As shown in Figure 4, runner exit place, spool body 3 lower end is a rectangle, and four jiaos of this rectangle are arc angling, and the groove of spool body 3 upper ends is not communicated with the runner of spool body 3 lower ends mutually in addition.As shown in Figure 6, the present invention changes the water passage surface in the spool into airflow design, has strengthened the negotiability of fluid; Prevent to stop up, spool is easy to spraying or built-up welding is handled, and hardness can reach more than the HRC70; Serviceability temperature is also brought up to 500 ℃, thereby has improved the wear-resisting property of spool.
Claims (4)
1. a new coal powder is carried angle valve; Comprise spool body (3); It is characterized in that: said spool body (3) thus the upper end has groove and is connected with valve rod (1), and at spool body (3) thus the lower end is provided with runner supplies medium to circulate, and this runner internal surface is a curved surface.
2. a kind of new coal powder as claimed in claim 1 is carried angle valve, and it is characterized in that: wherein the bending direction of runner negative camber is identical with the medium circulating direction.
3. a kind of new coal powder as claimed in claim 1 is carried angle valve, and it is characterized in that: wherein runner exit place, spool body (3) lower end is a rectangle, and four jiaos of this rectangle are arc angling.
4. carry angle valve like any described a kind of new coal powder in the claim 1 to 3, it is characterized in that: wherein the groove of spool body (3) upper end is not communicated with the runner of spool body (3) lower end mutually.
