Abstract
The present invention discloses a double-cup double-passage transversal fat filling method for performing a sealing action between an upper inner cavity and a lower inner cavity of a valve type orifice plate throttling device. Sealing fat can be filled in by two fat filling cups, the sealing fat is delivered into grooves positioned at both sides of each inner cavity on the sealing surface of a sealing slide seat in a lengthwise direction by the grooves positioned at both sides of each inner cavity on the sealing slide seat in a lengthwise direction, and the sealing fat is filled up in the grooves. The present invention has the advantages of good sealing effect, simple structure and low cost.
Description
The present invention relates to flow measurement primary instrument class, the horizontal grease injection methods of two cup Twin channel of the valve-type orifice-plate throttling arrangement in a kind of especially flow measurement that is used to gas such as rock gas and liquid widely.
The grease injection method of existing valve-type orifice-plate throttling arrangement is a single channel, be provided with a pair of lateral trench in the opposing one side of sealing slide sealing surface, its seal gease can not be full of the sealing surface groove fully during greasing, do not reach good sealing effect, easily cause valve-type orifice-plate throttling arrangement upper and lower cavity dielectric leakage, make the valve-type orifice-plate throttling arrangement inaccurate when metering, error is big, can't satisfy the accurate requirement of device, " being applicable to the profiled seal slide plate of valve-type orifice-plate throttling arrangement " that the applicant " is applicable to the horizontal grease fillers of two cup Twin channel of valve-type orifice-plate throttling arrangement " and is mated use declared utility model patent, improve from apparatus structure, improve the validity of sealing effect and device.
The purpose of this invention is to provide a kind of horizontal grease injection method of two cup Twin channel that is applicable to the valve-type orifice-plate throttling arrangement, the two cup horizontal grease fillers of Twin channel and the profiled seal slide plate that are applicable to the valve-type orifice-plate throttling arrangement that this grease injection method and the applicant propose are used, can guarantee that valve-type orifice-plate throttling arrangement upper and lower cavity medium does not leak, good sealing effect, improve valve-type orifice-plate throttling arrangement measuring accuracy and Security, and grease injection method is simple, convenient operation and control.
The object of the present invention is achieved like this: the present invention includes greasing cup, the greasing passage, groove, greasing hole and profiled seal slide plate, its grease injection method is: under specific temperature-20 ℃-160 ℃, seal gease is injected by two greasing cups simultaneously, the pressure that injects seal gease is greater than 0.2 MPa, seal gease by the greasing passage in the sealing slide bottom surface between the lower inner cavity on the valve-type orifice-plate throttling arrangement, be positioned at the groove of inner chamber both sides and, seal gease delivered to sealing slide sealing surface be positioned at the groove of inner chamber both sides and be full of groove fully by sealing slide upper edge length direction along length direction perpendicular to some greasings hole of groove.When moving the special-shaped close slide plate be close on the sealing slide sealing surface, seal gease can evenly laterally inject on the sealing surface, thereby is sealing between the inner chamber on the valve-type orifice-plate throttling arrangement.
Greasing cup of the present invention is positioned at totally 2 of bonnet lower both sides, and the greasing passage is communicated with greasing cup, is positioned at the sealing slide, the lower end is communicated with the groove that is positioned at the inner chamber both sides, the opposing one side of sealing surface at the sealing slide has a pair of lateral trench, the vertical and groove in greasing hole, and more than at least 2.Seal gease laterally injects on the sealing surface of sealing slide, the profiled seal slide plate is to have the long strip groove on the square bar of a block length along its length in the neutral position, respectively there is the geometrical shape of a boss below, edge, both sides along its length, the profiled seal slide plate is used with the sealing slide, its amount of deformation is little, good airproof performance.
Its seal gease can be full of the sealing surface groove fully during greasing of the present invention, plays good sealing effect, and medium does not leak measuring accuracy and the Security that has improved the valve-type orifice-plate throttling arrangement, and grease injection method is simple, convenient operation and control.
