The adjusting device comprises a valve core and a valve seat. The valve seat is fixedly connected with a cylinder cap, and the inner wall of the valve core is in surface contact seal with the external surface of the valve seat; a compression bar connected with a piston is arranged on the valve core which can reciprocate in the axial direction through the piston and the compression bar; the valve core which is provided with a plurality of limiting bolts is integrated with the valve seat through the limiting bolts, and springs are arranged on the limiting bolts between the valve core and the valve seat; a plurality of windows are evenly distributed on the external surface of the valve seat; an end cap in which the piston is arranged is fixedly connected with the cylinder cap, and the end cap is also provided with a connection pipe connected with pressurized gas. According to the utility model, the ground plane seal between the valve core and the valve seat can reduce the impact and damage caused by the opening and closing of the valve core; the positioning between the valve core and the valve seat is correct, the contact of the sealing plane is close, and the assembly difficulty is greatly reduced.
Description
Technical field
The utility model relates to the fixedly controlling device of clearance volume of gas compressor, specifically a kind of clearance valve-regulated devices of regulating cylinder clearance volume and then regulating compressor volume efficient.
Background technique
At present, the clearance valve that is used to regulate cylinder clearance volume comprises the spool and the valve seat of split, and spool inwall and valve seat outer wall are the conical surface, and seal form between the two then adopts conical surface contact seal.Because spool and valve seat are splits, just spool is enclosed within on the valve seat or with spool vertically and opens by the pull bar on the spool, there is not accurate in locating between spool and the valve seat.Therefore, be difficult to realize line contact sealing completely between spool and the valve seat.And through long-term use, the conical surface surface of contact of spool and valve seat is easy to produce impact failure, thereby produces gas leakage, influences the proper functioning of compressor.
In addition, when spool is in the closed position, gas pressure in the cylinder need be born, when in-cylinder pressure is higher, the spool operation easier can be increased.
The model utility content
In order to solve the problem of existing clearance valve seal form defective, the purpose of this utility model is to provide a kind of reliable sealing clearance valve-regulated devices.
Another purpose of the present utility model is to provide a kind of clearance valve-regulated devices that can keep the long-term operation reliability.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises spool and valve seat, and valve seat is fixed on the cylinder cap, and the inwall of described spool and the outer surface of valve seat are face contact seal; Spool is provided with the depression bar that connects piston, and spool can move back and forth vertically by piston and depression bar.
Wherein: described spool is provided with a plurality of caging bolts, and spool connects as one by caging bolt and valve seat, is provided with spring on the caging bolt between spool and the valve seat; The outer surface of valve seat is evenly equipped with a plurality of windows; Be provided with a plurality of seal rings between described spool inwall and the valve seat outer surface; Be connected with end cap on cylinder cap, piston is placed in the end cap, also is provided with the adapter that is connected with compressed gas on the end cap.
Advantage of the present utility model and good effect are:
1. be plane sealing between spool of the present utility model and the valve seat, reduced the impact failure that the keying because of spool brings through grinding.
2. spool of the present utility model and valve seat are assembled into one by caging bolt, the keying of spool realizes by depression bar and Returnning spring, can guarantee the accurate location between spool and the valve seat, guarantee that spool contacts tightly with the sealing surface of valve seat, and greatly reduced assembling difficulty.
3. valve seat external peripheral surface of the present utility model is uniform a plurality of windows, spool no longer needs to bear gas force, bringing great convenience for the keying operation of spool.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial enlarged drawing among Fig. 1;
Fig. 3 is that the A of Fig. 2 is to view;
Wherein: 1 for taking over, and 2 be piston, and 3 is depression bar, and 4 is spool, and 5 is seal ring, and 6 is window, and 7 is valve seat, and 8 is caging bolt, and 9 is spring, and 10 is cylinder cap, and 11 is fixing clearance chamber, and 12 is end cap.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～3, the utility model comprises that radial cross section is circular spool 4 and valve seat 7, and valve seat 7 is fixed on the sidewall of cylinder cap 10.Be provided with clearance chamber 11 in the cylinder cap 10, be connected with end cap 12 with bolt, which is provided with the adapter 1 that is connected with compressed gas at the opposite side of cylinder cap 10.The seal form of the outer surface of the inwall of spool 4 and valve seat 7 is the face contact seal through grinding, and is provided with a plurality of seal rings 5 between spool 4 inwalls and valve seat 7 outer surfaces.Spool 4 is provided with depression bar 3, and the other end of depression bar 3 is connected with the piston 2 that is placed in the end cap 12.Spool 4 can move back and forth vertically by piston 2 and depression bar 3.Spool 4 is provided with a plurality of caging bolts 8, and spool 4 connects as one by caging bolt 8 and valve seat 7, is provided with spring 9 on the caging bolt 8 between spool 4 and the valve seat 7, is used for spool 4 and resets.The outer surface of valve seat 7 is evenly equipped with a plurality of windows 6.
Working principle of the present utility model is:
When spool 4 was opened, the gas in the cylinder communicated by the window on the valve seat 76 and cylinder cap 10 interior fixedly clearance chambeies 11, realizes the adjusting of cylinder clearance.When cylinder needs less clearance volume, earlier compressed gas is charged in the chamber, left side of end cap 12 and piston 2 formation by taking over 1, compressed gas promotes piston 2 and depression bar 3 moves to the right, and then promotion spool 4 pressure springs 9, the spool 4 and the abradant surface of valve seat 7 are compressed, and spool 4 is enclosed within the outside of valve seat 7 gradually.Window 6 on the valve seat 7 is closed gradually, makes that gas and the fixedly clearance chamber in the cylinder cap 10 11 in the cylinder is isolated.When cylinder needs big clearance volume, the left side cavity emptying that piston 2 and end cap 12 are formed earlier, compressed gas is in the quilt process of emitting, spool 4 is subjected to the power to the right that compressed gas applies and reduces gradually, and under the elastic force effect of spring 9, spool 4, depression bar 3 and piston 2 are moved to the left gradually, window 6 on the valve seat 7 is opened gradually, by emptying, spool 4 limited bolts 8 block until chamber, piston 2 left side, and window 6 reaches maximum.At this moment the gas in the cylinder communicates by window 6 and cylinder cap 10 interior fixedly clearance chambeies 11, and cylinder clearance increases to maximum gradually.
